President’s Message
T
he President's message is often really difficult for me to write for some reason. There is so much information to relay to you that it is overwhelming sometimes and really difficult to narrow the focus. This message is a little different. It is a little easier because I have a lot of people to thank for helping me through this past year as your President. But then it gets difficult again because there are so many people to thank and I am sure that I will overlook someone. We have a wonderful organization composed of everyone from the Past Presidents to our newest member, and it has been my pleasure to serve as your President. I thank you, all of you, for the support and advice you have given me over the past year. The Texas Section has a wonderful leadership team. The Executive Committee and Board of Direction have been welcomed to voice their opinions on everything from committee structure to budget items. We have not always agreed and there have been some lively discussions that have pushed our meetings to the limits, but all in the interest of doing what is best for the Texas Section and what our founding members almost 100 years ago envisioned. I thank each of you for your participation, dedication and responsibility to the positions you serve.
Ralph M. O’Quinn PE Texas Section President
I thank you, all of you, for the support and advice you have given me over the
We accomplished most of our goals this year including updating the Infrastructure Report past year. Card and involving students more in the meetings. If you were at the San Antonio meeting luncheon, you saw a video presentation by middle school students that literally was out of this world. The Infrastructure Report Card is on track to be released at the Texas Section Fall Conference in Fort Worth with a follow up media event on the steps of the Capitol in January as part of the Centennial year celebration. The Centennial Planning Committee has been working very hard to gear up for the Centennial year. You will have plenty of opportunities to participate either at the local or state level. See page 38 for additional information on the Centennial CELEBRATION.
Last but certainly not least, it would have been very difficult to perform the duties of this job without the assistance of the Texas Section office staff of Cres, Elizabeth and Kathryn. They are a tremendous asset to the organization and we are blessed to have them with us. My thanks to you all for your support during this year. I look forward to seeing you all in Fort Worth!

We have a fantastic Fall Conference coming up in November in Fort Worth and it is one that you will not want to miss. The Fort Worth Host Committee has done a tremendous job of making this THE conference that will establish how our conferences are done in the future. This will be three conferences in one with the Construction Institute and the International Committee on Sustainable Design, Engineering and Construction partnering with the Section and providing lots of additional content for attendees.

Message from the Executive Director "The only constant in life is change." Crespin Guzman PE Executive Director
No doubt you have heard this old saying. Well, earlier in the fiscal year I told you about some changes that were to come as the year rolled along and now some of that has happened. So guess what—more are on the way. This is no time to rest on our laurels, but instead to get up a full head of steam and focus on what lies ahead!
Civil Engineering Trivia
Name the three oldest ASCE Texas Section Branches.
www.texasce.org
See page 41 for the answer

And what is ahead of us you ask? Only the most significant period of preparation in establishing an enhanced "paradigm" to our conferences that makes partnering and sharing into winwin situations for the Branches, the Institutes and the Section. If this sounds like increased opportunities for networking, then it is; if it sounds like opportunities for greater learning, then it is that also. It is everything that is good about being a part of a larger group of peer professionals with new, different and exciting programming activities. Just check out the Fall Conference program schedule (on page 15) and you'll see what I mean. So where else will our paradigm transform? Look at the Section office, the communications hub for the membership and what is in the works there to improve communications with, and for, our members. Our website is being redesigned for a more contemporary look and to have advanced capabilities that will benefit you; the redesign is planned to be complete this fall in advance of the Fall Conference in Fort Worth. Then comes the Texas Civil Engineer magazine (TCE) and how it's going to look and fare in its electronic format, which we will hopefully roll out in time for the Centennial year. We want your feedback on this matter so please share your opinion with us. And what better way to make your voice heard than to use our social media platforms. The Texas Section's many ways to share and interact with each other facilitates greater communication amongst all members in Branches and Sections within Region 6. So how do these changes affect you? If you do not participate even in the slightest of all changes, then it probably won't have an effect. However, if you get involved and become an active member at the Branch or Section level, you can expect to experience a shift in "your paradigm" of the ASCE in Texas. And that is a good thing, because the change will provide you with opportunities to become a potential leader as we usher in our Centennial Celebration in 2013! What are you waiting for?

A New Vision for For t Wor th By the Trinity River Vision Authority
When Texas residents hear about waterfront development, "tubing" on the river, canals, sustainable growth and watersports such as kayaking or stand up paddle boarding, they naturally think of places like Austin or San Antonio. However, the Trinity River Vision project has brought all of this to "Cowtown," and you're going to have to add one more city to that list: Fort Worth.
Trinity River Vision Master Plan

The Trinity River Vision (TRV) Master Plan connects Fort Worth neighborhoods to the 88 miles of river and tributaries that run throughout the city. In addition to community events that celebrate the river, the TRV delivers over 90 capital improvement projects that enhance open spaces, add user-recommended recreational amenities, provide more river access, inspire public art projects, create waterfront development opportunities and build out some of Fort Worth's most cherished urban parks along the river.
Trinity Uptown

Central to the plan is "Trinity Uptown," which is an 800 acre underutilized industrial area located along the Trinity River adjacent to downtown. Through enhanced flood control, smart growth planning and critical transportation improvements, Fort Worth is fostering a walkable, high-density, mixed-use neighborhood in the central city - a viable, sustainable alternative to suburban sprawl. The $909 million infrastructure project includes the construction of a 1.5 mile bypass channel, isolation gates, three vehicular bridges, dams, and a vibrant urban waterfront and Town Lake. The new flood control system provides flood protection and allows massive levees to be removed allowing development to occur along the riverfront. Upon completion, this project will nearly double the size of the central business district, create over 16,000 permanent jobs and add over 3 million square feet of commercial, retail and educational space.
Partnerships
www.texasce.org
Fort Worth has seen a staggering 39 percent population increase in just 10 years, just over 250,000 people. To accommodate for this growth and address long-term transportation and growth patterns for our region, a cooperative partnership including City of Fort Worth (CFW), Tarrant Regional Water District (TRWD), Tarrant County (TC), U.S. Army Corps of Engineers (USACE) and Texas Department of Transportation (TXDOT) have committed to the construction of infrastructure associated with Trinity Uptown.

The partners have used numerous programs and policies to control development and implement sustainable practices.
The Trinity River Vision Authority (TRVA) was created to provide a vertical management system for the project. The TRVA Board is made up of a top-ranking elected officials and top-ranking staff from each local partner. Monthly meetings allow partners to review schedules, financials, policies and progress, assuring accountability for each agency's contribution.
Development Land use is regulated through mixed-use zoning promoting a live, work, play envibased code requires private development to conform to design ronment. A form-b principles that enable a pedestrian-oriented, dense neighborhood to function. Minimum height requirements ensure high-density, compact urban development in
FALL 2012 • VOLUME 82 • NUMBER 4 Fort Worth's central city where resources and services are already in place. Development standards allow incentives for the construction of LEED certified buildings and require the use of quality materials in new construction. Shared public parking garages built through public/private partnerships utilize less space and reduce the need for surface parking. An innovative stormwater management system will manage runoff through a series of canals, replacing conventional underground conveyance systems. The canals will provide a continuous public boardwalk, enabling activities along the water's edge. New roads and bridges will accommodate a future mass transit system that will connect Trinity Uptown to downtown establishing efficient access. Future local streets will be purposely narrowed to a small footprint to ensure pedestrian activity and comfort. A circulator road around the perimeter will connect development nodes. The new infrastructure combined with the development standards will create an attractive neighborhood with a strong sense of place.
Sustainability It is because of these initiatives that the project has been recognized for Modern streetcar. Image courtesy of Trinity River Vision sustainable practices. In 2011, Authority. USACE awarded the Trinity River Vision Central City Project Delivery Team the National Green Gov Good Neighbor Award to recognize and reward their excellence in the development, management and transferability of activities, and programs that improve environmental quality, enhance the mission and help USACE reach its sustainability goals. Additionally, the North Central Texas Council of Governments, American Planning Association, International Waterfront Center and numerous other organizations have recognized the planning and public policy efforts associated with the project.
Recently, a $22.3 million commitment was made to commence construction of the White Settlement Bridge and Roundabout in 2013, the third and final Trinity Uptown Bridge that has yet to receive full funding. U.S. Transportation

Community Activities
The Trinity River Vision project truly is transformational for the City of Fort Worth. It isn't just one policy that promotes one aspect of smart growth; it combines multiple policies, programs and projects to deliver future viability and sustainability for the city. Urban living, transportation alternatives, environmental clean up and quality of life elements like the riverwalk have to be in place to continue to bring growth back to the central city.

Even before the infrastructure is in place, there is energy and excitement growing in Trinity Uptown. TRVA programs the public spaces to foster a sense of place and community connection to the area in the interim. TRVA coordinates events at the Panther Island Pavilion - a waterfront stage and festival area in the heart of the neighborhood. Events such as the "Rockin the River" summer tubing and music events have provided an opportunity for all ages to enjoy the river. An annual Fourth of July celebration takes place at Panther Island Pavilion with free music and family activities. In addition, numerous concerts, festivals, mud runs and 5K races are held in the area each year. Panther Island Pavilion is the home to stand up paddle board and kayak rentals, making it a one-stop shop for watersports. These activities strengthen community connection to the river and the neighborhood. A food truck park and a new urban model drive-in theater are also opening in the district, approved as temporary uses until the development goes vertical.

A Vik K. Verma PE, SECB VP Professional Affairs
fter three years and nine extensions, Congress passed a 2-year transportation bill at the end of June that has been signed into law by President Obama. The Moving Ahead for Progress in the 21st Century Act (MAP-2 21) reauthorizes taxes that support the Highway Trust Fund through September 30, 2016, and the authority to make expenditures from the Highway Trust Fund through September 30, 2014. MAP-21 is not as long as would be desired—the SAFTEA-LU transportation bill that preceded MAP-21 was a 4-year bill. However, it will provide additional certainty that will allow for greater planning ability as it relates to transportation. And it now gives us a launching pad to work for more—far more.
So let's keep talking to our legislators. Let's give them our expertise. Let's move the needle.
As we move forward, there is a definite need for a long-term six-year bill that addresses funding issues and makes further progress in addressing our infrastructure issues. We also need to push for greater levels of funding on an annual basis. I hope that ASCE at the national level moves forward to produce a model bill that can be presented to our legislators in time for 2014, when a new transportation bill will need to be passed. While this model bill may not end up being passed as actual legislation, it can and should serve as a driving force for the discussion moving forward. As ASCE members, we definitely have the expertise and passion to help shape this discussion, and we should be involved in this process. So let's keep talking to our legislators. Let's give them our expertise. Let's move the needle. On another note, the 2013 Texas legislative session will be here before we know it. Committees will begin meeting this fall to discuss what legislation will be introduced. The ASCE Texas Section will be monitoring the progress of these committees and keeping you posted on what is transpiring.
www.texasce.org
Also, work on the ASCE Texas Section Infrastructure Report Card is proceeding nicely and will be ready for unveiling at the Texas Section Fall 2012 Conference in Fort Worth. The Infrastructure Report Card Committee led by David Calabuig, in conjunction with our consultant Susan K. Roth Consulting, has done a great job putting this report card together and doing the extensive research necessary to make it happen. Once published, this will give us a powerful tool to use when we talk to our legislators about improving our infrastructure.
12
Finally, the ASCE Texas Section is undertaking an initiative to improve and enhance our community involvement efforts statewide. In particular, a Community Involvement Committee will be developed that includes members from each branch. The plan is to have a Community Involvement Chair for each branch and have events statewide. Community Involvement is an integral part of the strategic plan of the Texas Section, so we encourage all members to get involved in these worthy endeavors.

Grant, and was developed by the ASCE CI Crane Safety Committee, based on Manual 93: Crane Safety on Construction Sites. Recent costly and high profile crane accidents demonstrate a need for specialized training and certification for crane erection, jumping, and dismantling. The objective of the CI training course is to provide a program for Project Managers, Project Engineers and others whose responsibility includes the installation, movement, use and dismantling of cranes and lifting devices utilized on construction sites. With a focus on raising awareness of safety issues and the causes and cost of crane accidents, while addressing the changes put forth with OSHA's updated rule for cranes and derricks, this program increases the ability of engineers and supervisors to utilize their technical training and management skills on the construction site, in order to implement safe crane operations.

Automated Development of As-B Built Construction Schedules Danny L. Kahler PE As-built project schedules are necessary to close out construction projects, defend against disputes, and provide feedback to improve the estimates of future construction project schedules. However, the development of the as-built schedules is typically left until the end of the project, is often prepared with bias, and usually does not accurately represent the actual schedule performance of the project due to subjective and outdated information. This session will present a method of automatically building as-built construction project schedules from the traditional daily inspection reports that almost all transportation agencies use. The advantages of this method are: 1) Development of the as-built schedule does not add any additional workload to the project staff, since it is built from data that is already collected by inspectors and project engineers 2) Multiple stops and starts of project activities can be captured, as well as daily production rates 3) The actual progress of schedule activities are automatically updated based on cost-loaded work or pay items with quantities and unit prices 4) Inspectors and project engineers become immersed in the CPM schedule as a part of their daily routine, improving the control of the project 5) The information that builds the schedule is current and objective.

Prioritizing Project Requirements Through Risk Engineering Danny L. Kahler PE The traditional approach to verifying project requirements has often been based on the concept of mass inspection; more reviewers and more inspectors means better compliance and reduced risk. Owners, however, have discovered the diminishing return of paying armies of full-time staff to verify routine or low-risk requirements. Since the main goal of verifying project performance is to reduce the risk of failure, why don't we manage our project requirements according to risk? This session will present innovative concepts in assigning risk values to project requirements in all areas of construction, including performance, quality, and specifications. These risk values are based on an objective, scientific approach to both actual failure and the likelihood of the constructor not meeting the requirements. Verification is tightened for high risk requirements, relaxed on low risk ones. This standard methodology helps to avoid the normal tendency of personnel to focus energy on verifying requirements based on individual perceptions, such as failures on past projects, pressure from management preconceptions, or a person's comfort level within a particular technical area. This engineering-based risk analysis method also provides a plat-
form for objectively analyzing how to install detection control reduce the severity or probability of failures. Methods for Fabrication of Polyurethane-S Stabilized Ballast Dr. Randall W. Brown; Dr. Tuncer B. Edil; Andrew K. Keene; Dr. James M. Tinjum Between 1980 and 2008, traffic on Class 1 railroads has increased 93 percent and total track length has decreased 42 percent, leading to a substantial increase in traffic density and maintenance requirements. To improve maintenance techniques for problematic rail infrastructure elements (i.e., bolted rail joints, intersections, bridge approaches, etc.), a method involving polyurethane reinforcement of the ballast layer is proposed. Presented are a set of criteria by which the mechanical properties of the ballast layer were improved with polyurethane injections. These criteria include: (1) extent that the void space of ballast was filled by the RPF, (2) strength and degree of bonding that occurred between the ballast particles and RPF, and (3) limiting volumetric expansion of ballast during RPF injection. Injection of the polyurethane into the ballast layer creates a composite material of ballast bound with the polyurethane. Injection quantities used during laboratory specimen fabrication were evaluated to minimize polyurethane expansion/reaction pressure. The developed procedure is aimed at optimum void filling behavior that would resemble best practice for a field procedure. Ideal field practice involves filling the ballast pore space in targeted areas while producing minimal expansion thereby preserving ballast layer mechanical properties and geometry and minimizing quantity of polyurethane injected. Procedures developed and presented herein reveal that strategic polyurethane injections can be achieved so that quantified injections are conducted and ballast layer mechanical properties enhanced. Evaluating the Impact of BIM on Construction Accidents Happening Mohammad Kasirossafar The idea of Prevention through Design Addresses occupational safety and health in the design process to prevent or decrease the work-related hazards and risks associated with the construction, manufacture, use, maintenance, and disposal of facilities, materials, and equipment. Prevention through Design can be used to achieve sustainability through design and ensure that the resulting safety, energy and environmental benefits can be at their highest levels for workers, the public and the environment. 3D/4D Computer-Aided Design software and Building Information Modeling are the newest types of Prevention through Design tools. 75% of the respondents to a survey thought that construction accidents

Heavy Crane Lift Selection Richard L. Mikut Jr A myriad of factors must be looked at simultaneously to properly select a heavy lift crane for a specific job. There are various types of cranes including crawler, tower, ringer, derricks and more. The type of crane, the size of the load, site constraints, rigging deducts, ground-bearing pressures, crane efficiency and rental costs must all be taken into account. This paper will discuss how to take all of these issues and constraints into account when selecting the proper heavy lift crane. Knowing the weight and dimensions of the component to be lifted is a critical element, but there are many other items that should be considered. Site constraints may actually impact the selection of the crane more than the lifted element itself. Also, when sizing the crane, the weight of the rigging, the crane block, line weight and other items below the boom point must be added to the load weight. Another major factor during crane selection is the groundbearing pressure imposed by the crane and the ground preparation needed. These costs can add up depending on what crane is selected. Cost must be heavily considered. Taking these and other factors into account, a properly sized heavy lift crane is an important component to completing a job safely and effectively. Four major takeaways: 1) Groundbearing pressure matters, more research is needed. 2) More than just the load, remember your deducts. 3) Site constraints may have more to do with sizing the crane than the load itself. 4) Lowest rental cost isn't always the best cost. Using Digital Design Data in Construction Danny L. Kahler PE Almost all design is done in 2D digital files, yet most activities in construction still rely on analog plans sheets, whether copied directly from mylars or printed from PDF files. This legacy practice results in bottlenecks to schedule and efficiency, loss of value as information in the design files has to be re-created by the contractor from the analog plans, and the introduction of additional errors and omissions as contractors try to reverse-engineer these analog plans back into constructible digital models. While there has been a lot of excitement, most of it hyped, about the potential of delivering fully-integrated 3D models directly to construction, there may be overlooked opportunities to immediately use the 2D information that is already being created by existing design processes. Discovering new technologies and practice methods that can make immediate use of the 2D information created in the typical modern design process can produce faster
returns on investment, as well as provide a stronger base for the long-term goal of more sophisticated and integrated design information transfer. These practice methods and technologies could include, but not be limited to, Geospatial PDF Plans, Direct Importing of Design Files and Coordinate Geometry, Use of GIS in Construction, and Improving Design File Quality This subject is relevant to design engineers who currently produce the design files, the owners who will review the design files, the surveyors who will use the design files to lay out the work, the contractors who will use the design files to construct the work, the construction engineers who will use the design to inspect and accept the work, and the hardware and software vendors who will provide the tools. This session will focus on the potential of existing technologies and practice methods, already being used in other areas of engineering such as military mapping, oil and gas production, and manufacturing, that could be quickly adapted for design and construction in the built environment. Some technologies may be immediately usable but require improved engineering and survey practice methods, while other technologies may need to be modified to conform to those legacy practice methods that have greater inertia. The goal of this session will to be focus on those opportunities that have the best chance of being deployed and used by mainstream practitioners, given the current constraints of owner agency organizations, legacy practice methods, and technology reliability and cost. Evaluating Alternative Quality Management Systems for Civil Engineering Construction Danny L. Kahler PE Traditional quality management systems for civil engineering have been based on the idea that more is better. In other words, the perception has been that more inspection, more sampling, and more testing results in more quality. However, stakeholders are beginning to learn that there is not a direct relationship between this brute force approach to controlling and assuring quality and the actual quality of the project. At the same time, stakeholders are also slashing budgets to reduce any activity that isn't critical to the short term success of their projects, even if may threaten long term success and sustainability, which are ultimately the goals of modern quality management. Faced with the obsolescence of these traditional and legacy approaches to managing quality, civil engineers need the ability to objectively evaluate alternative methods to avoid shooting in the dark, i.e. picking an unfamiliar system without knowing its ultimate effect on the project goals. This session will present an approach to evaluating these alternative systems based on the their positive and negative characteristics within three areas: 1) Efficiency—the basic cost effectiveness of the system relative to the cost of the project, 2) Effectiveness—the reliability of the control and assurance of the system in preventing defects that could result in short or long term failures, and 3) Accountability— the clear assignment of responsibilities within the system to people who are not only qualified but publicly and professionally accountable. Using these three criteria for evaluation of a system will help to match the capabilities of any system to the unique risks and constraints of the type of project that's being constructed.

can be eliminated or lessened through using Building Information Modeling and visualization technologies. The highest three ranking in order of most preventable category of accidents were falls from height, cuts or blows from objects and tools, and thermal contacts or electrical shocks. Building Information Modeling analysis improves design team member's ability to visualize and conceptualize the construction process, which decreases the rate of interpretation and makes easier and better communication among various stakeholders. This will make ease in correct choices among different designing options and in some cases even would be ended in the new design suggestions.

Sugar Land's Integrated Surfacewater Treatment Plant Delivery Approach: Saving Cost Jessie Li PhD, PE; Christopher Steubing PE CFM; Michael Lucchesi PE The City of Sugar Land considered multiple project delivery options for the new 9 million gallon per day (MGD) surface water treatment plant (SWTP) developed to meet Fort Bend Subsidence District groundwater consumption reduction mandates. The SWTP, with an initial capacity of 9 million gallons per day (mgd) expandable to 22 mgd, allows the City to meet requirements of providing 30% and 60% groundwater reduction by the year 2013 and 2025, respectively. The plant incorporates conventional pre-treatment followed by robust microfiltration and granular activated carbon (GAC) to treat raw surface water from the Brazos River. In order to ensure on-schedule and cost-effective delivery of the first SWTP, the City chose to implement the construction manager at risk (CMAR) delivery method combined with a 1-year period of extended plant contract operations. The CMAR delivery approach combined with initial contract plant operations allowed close coordination between the City and the CMAR's value engineering (VE) and water plant operations specialists during the pre-construction phase of the project. Through a detailed review of the initial SWTP design documents, the team identified over 25 individual value engineering and operational cost savings ideas while maintaining compliance with treated water quality goals developed during SWTP pilot testing, resulting in approximately $25 million in capital and operation cost savings without impacting or sacrificing the design or functionality of the plant. This paper highlights the benefits of this innovative alternate project delivery approach which integrates pre-construction, construction, and plant operations to achieve significant lifecycle cost savings in a collaborative Owner–Designer–CMAR relationship. Demonstrated capital and operational cost benefits are highlighted along with a detailed description of the delivery process, plant operational review/philosophy and unique water utility advantages gained from this innovative delivery approach.

Successful Installations of Polypropylene Pipe in Demanding Sewer Applications Daniel Currence PE Though utilized globally for over 40 years, pipe made of polypropylene has recently joined the list of viable storm and sanitary sewer materials in the United States. The material characteristics of polypropylene make it ideal for sanitary trunk sewer and demanding storm sewer applications. Pipe made with polypropylene combines the pipe stiffness and beam strength expected in a PVC pipe with the ease of handling, chemical resistance, and impact resistance valued in a high-density polyethylene (HDPE) pipe. Advanced Drainage Systems, Inc. (ADS) manufacturers profile wall polypropylene pipe that meets all requirements of ASTM F-2736 in 12-inch to 30-inch diameters; larger 30-inch to 60-inch diameter polypropylene pipes are manufactured with a unique triplewall design meeting the requirements of ASTM F-2764. The SaniTite HP is manufactured in Ennis, Texas in 13-foot and 20-foot standard lengths. The SaniTite HP pipe includes a robust joint with an extended reinforced bell and an extended spigot with double gaskets. This joint has passed a rigor-
ous 1000-hour pressure testing, far exceeding the requirements of ASTM D3212 and the expectations of other pipe joints. Increasingly, agencies and design engineers are recognizing the value pipe material competition brings to a pipe installation project. For many communities, large diameter trunk sewer projects occur infrequently and consume budgets that are already stretched. Therefore, engineers look for sanitary sewer materials that will maximize design service life and competition among viable pipe types to lower costs. This was indeed the case on a project installed in 2012 in Grimes, Iowa, a suburb of Des Moines. Fox Engineering evaluated SaniTite HP to be an equal alternative and incorporated it into the design for 5,000 of 36-inch and 48-inch diameter outfall sewer. Based on historic regional bids, it was determined that polypropylene pipe saved approximately 30 percent compared to traditional materials. The contractor, Keller Excavating was able to begin construction during the winter of 2012 and concluded in May. Engineers and contractors are also selecting polypropylene because of its ease of handling and the ability to accelerate construction. The 5,600 feet of 60-inch West Side Interceptor sewer in Portland, ME, was completed in October 2010 after just five months of construction. The City and Woodward & Curran included SaniTite HP as an equal alternative to epoxy-coated, reinforced concrete and centrifugally-cast glass fiber reinforced polymer. The contractor, R.J. Gronlin & Sons Inc., selected SaniTite HP in large part due to the ease of handling in restricted areas, the ease of tying HP pipe into T-bases and Inserta-Tee fittings and the overall resulting speed of installation. Demanding storm sewer projects may also be appropriate for polypropylene pipe. Storm drainage improvements at Port Columbus International Airport required over three miles of 30-inch through 60-inch diameter storm sewer. The CH2M Hill and the Airport concluded ADS HP pipe could be used as an equal to Class IV reinforced concrete pipe. The contractor, George J. Igel & Co., Inc., preferred the polypropylene because of it is resilient to the harsh environment of job-sites, light-weight, and easily maneuverable, even the 60-inch diameter sections. In Texas, polypropylene pipe has been used for a sanitary sewer trunk line in Waco, designed by LAN, and as a by-pass line in Dallas for the Trinity River Authority. The University of Houston is also conducting an extensive evaluation of polypropylene pipe. The ADA and the FHA: What Civil Engineers Must Know Mark J. Mazz The Americans with Disabilities Act (ADA) and the Fair Housing Act (FHA) are civil rights laws that provide freedom of movement for individuals with disabilities. Most civil engineers involved in commercial and residential construction do not know how much the ADA and FHA affect their work. These laws require all commercial development and most multifamily and attached-dwelling sites to be accessible to persons in wheelchairs. All multifamily buildings must comply. FHA considers townhouse developments as multifamily when there are at least four attached dwelling units with at least one single story ground floor unit or at least one dwelling unit has an elevator option. Until recently, the Department of Justice (DOJ) and disability advocates focused their energies on architects and developers. Now they have

The Use of Linear Regression to Estimate the Actual Hourly Production of Wheel-T Type Loader in Construction Projects H. Nabizadeh Rafsanjani; Sh. Shahrokhabadi; A. Hadjahmadi The hourly production of heavy construction machinery is generally one of the key factors in the success of construction projects. It is clear that the nominal hourly production of the machinery provided by manufacturers differs from the actual hourly production at project sites. This paper presents a linear regression model to estimate the actual hourly production of wheel-type loader. The data of actual hourly production were gathered from literatures. The model establishes a practical link between engine power and actual hourly production of machine. The introduced regression model is certainly useful in planning machinery and can be a great help to the project management team.
Approach to Create a Generalized Stable Unsteady HECRAS Model Fari Nouri; Andres Salazar PhD, PE; Charles Penland PE; Andy Yung PE In large unsteady HEC-RAS models, substantial effort may be dedicated to stabilize one run. Models with hundreds of hydraulics elements are challenging and usually one particular scenario, say the 100-year event, is tackled at a time. Walter P Moore and Dodson Associates overcame this complexity in an unsteady HEC-RAS model of Buffalo Bayou and White Oak watersheds in Harris County that required high stability for any possible hydrograph entry, even no flow conditions. This paper summarizes the team's experience to solve key complexities of the HEC-RAS elements that cause instability and the approach taken to create a model suitable for real-time applications.
Incorporating Peanut Hull Fibers within Concrete for Strength Gain Halie Schmidley; Patrick Ryan; Daniel Steinbreche; Jason Charalambides Sustainability, waste management, and recycling of waste product were the concerns that lead to the concept of this paper. Peanut hulls are typically found in mass quantities therefore finding a means of reusing them in a sustainable manner was the approach of this research. The hulls contain cellulose, which has been proven to be a strengthening component found in peanut hulls among other organic substances. The study conducted lead to experimentation of possible recycling methods for the use of the available cellulose in peanut hulls to be incorporated within a concrete mix. It has been evidenced that under specific scenarios the contents of the peanut hull can impact the formation and strength of the concrete mix. In one specific setting the incorporation of hull fibers provided a higher compressive strength capacity to the mix, but caused side effects in the formation, leading to a very evident case of honeycombing. Nonetheless, with such a severe side effect, it was evidenced during compression tests on cylinders that the specific option raised the strength of the mix by approximately 20%. The actual transfer and mix of the cellulose within the cementicious mix is not observed, as the fibers were simply added unground. The use of extruded hull fibers was initially evaluated as possible minor aid toward hairline crack control but actually yielded a significant strength gain in compression. Although material that would have been rejected as waste was used, it should be noted that the focus of this study was
Receiving Stream Quality Impact from a Large Storm Water Siphon C. Raajan Mehta PE; Todd Woodson PE The City of Dallas is proposing a 30 ft. diameter, 2-mile long storm water tunnel which will operate under gravity, conveying collected storm water from a 3,200 acre basin and diverting it to White Rock Creek. This is segment 0827 of a TCEQ classified stream that has defined stream standards that must be maintained. Standards include maximum levels of chloride, sulfate, dissolved solids and coliforms, as well as a minimum dissolved oxygen concentration. Because the tunnel operates as a siphon, stormwater may be stored in the tunnel for long periods of time, and dissolved oxygen levels will sink. Stormwater discharges must not combine with baseline stream flow to the extent that predefined stream standards are not maintained. The primary objective of this report is to study potential impacts of the tunnel discharge into White Rock Creek and to determine an acceptable maximum rate of discharge. To accomplish this, samples of storm water runoff were collected, as well as samples from the receiving stream. Samples were "incubated" under conditions similar to those in the tunnel for period of 30 days. They were then analyzed for dissolved oxygen and other parameters. Data from the samples was used as input parameters to calculate the effect of the tunnel discharge on the receiving stream water quality. Two methods of analysis were required: 1) Streeter Phelps Calculation: This is required to determine the effect of the tunnel discharge on the receiving stream dissolved oxygen concentration, 2) Mass Balance Calculation to determine additional parameters.

begun targeting engineers. Therefore, it is important for civil engineers to understand the ADA and FHA accessibility requirements. Accessible routes cannot slope more than five percent unless handrails and landings are provided. Additionally, the accessible route cannot cross slope more than two percent. (Try that in asphalt over non-engineered soil!) Landings at doors cannot slope more than two percent. In addition, the accessible means of egress must extent to a public way or end at an area for assisted rescue. Consequently, civil engineers can no longer rely solely on standard curb ramp details and general notes about slopes and cross slopes. Potentially, every design tweak made by the owners and architects can affect the accessibility of the site design.

TEXAS CIVIL ENGINEER The Elusive 100-yyear Flood, Why Does It Keep Changing? T. Lynn Lovell PE, CFM; Walter Skipwith PE, CFM, D.WRE; Craig Loftin PE Data for the computed or published one percent (100-year) flood for many Texas creeks and rivers seems to be in an almost constant flux of change, usually increasing in discharge and elevation at many locations. The predominant use of the 100-year flood is for the National Flood Insurance Program and the floodplain maps that are published for FEMA. Many Texas cities and other agencies also use this particular flood event as a design flood for bridge openings, stormwater programs, and development criteria. The many factors that can cause these changes in published 100-year flood discharges and elevations are often represented by technical parameters in the computation and re-computation of the floods. What are the primary causes of these changes, over time? This paper will explore factors such as changes in urbanization, streams/floodplains, topographic data, modeling software, reservoir operation, historical flood records, as well as others that arise from time to time in the development of this information. A comparison of several case studies of streams and rivers in Texas where the 100-year flood has changed, over time, will be made. Historical and recent Corps of Engineer studies and data prepared by other federal, state, and local entities will be the source of this data set. The most probable factors for these changes will be enumerated and discussed and a set of conclusions regarding the subject will be made. Comments on the impacts to the public caused by these changes will be discussed also. The Green at College Park Larry Stone PE; Janna Tidwell RLA The Green at College Park is a showpiece for transforming a brownfield site into an artful solution of stormwater management. This three-acre passive park includes trails, benches, shade structures, and a large oval lawn area. For the students, it's a great place to hang out, study, or enjoy some Frisbee football with friends, but this is more than just a park. Along with structural drainage improvements, a number of surface enhancements play a significant role in cleaning the runoff and increasing infiltration. The project met a series of Sustainable Sites Initiative (SITES) performance bench marks and guidelines. The Green at College Park recently received a one-star certification and is currently one of three projects in the world certified by SITES.

Field Evaluation of Stabilization in Swelling Clay for Concrete Pavement Liong So PE, PMP This report contains field evaluations and multiple independent laboratory studies on subgrade stabilization of highly expansive clays found in the Dallas area. In the residential concrete pavement studies, two chemical additives were used: (1) an in-organic liquid soil stabilizer; and, (2) a liquid
polymer sealant. The field results showed dramatic improvement of subgrade stability for five alleys built in 2008 and a street constructed in 2009. Strength, stiffness, and durability were improved, while permeability and swelling potential were greatly reduced. Laboratory test results of samples gathered from the field proved that strength continued to increase after six months of stabilization. With the in-organic liquid soil stabilizer and liquid polymer sealant, subgrade stabilization does not need to be re-mixed, re-worked or allow 72 hours for curing, which is required when using the alternate conventional lime stabilization method. One hour after the subgrade is sealed with the liquid polymer sealant, as a fog seal, the treated subgrade may be opened to traffic. The two chemical additives were independently tested and found to be environmentally friendly with no danger to aquatic life. Both chemicals act as a non-toxic sealant and dust control. This eliminates particulate matter (PM10 and PM2.5) at construction sites. In residential concrete pavement, stabilization with these two additives provides less disruption to adjacent properties and energy conservation through the reduction of time, water, machinery, and labor. Structural Contribution of Lime Stabilized Soils Davor Simic PhD; Dallas Little PhD, PE Stabilization of fine-grained soils with lime is common practice throughout the world and especially in Texas due to the expansive characteristics of some Texas soils. The purpose of subgrade stabilization with lime, whether performed in situ or from borrow materials, is three-fold: to substantially reduce soil plasticity, and consequently its expansivity; to provide a moisture-stable layer that substantially reduces moisture fluctuations in the underlying expansive soils; and to significantly improve structural properties (compressive, tensile and flexural strength and resilient modulus or stiffness [MR]) of the soil stabilized. In fact, lime stabilization as proposed in this project transforms marginal soils into a subbase material with structural properties comparable with those of a granular base. Another important contribution of the lime stabilized soil (LSS) to the pavement structure is long-term strength: the pozzolanic reactions that take place between lime and soil and which can continue to develop and "heal" damage for many years. Although these reactions between lime and soil have long been recognized, the structural benefits of lime have seldom been considered in structural design. The structural benefits of LSS are described following the AASHTO 1993 Guide for Design of Pavement Structures. A rigorous quality assurance (QA) protocol, implemented by the "Developer", is described and results of the QA program are presented that demonstrate the success in achieving the target AASHTO structural layer coefficient for the LSS. The QA protocol is based on a systematic plan containing compressive strength testing and back-calculations for Falling Weight Deflectometer (FWD) testing and in some cases Dynamic Cone Penetrometer (DCP) validation.

Optimizing Designs to Accommodate Dwindling Resources Michael D. Roland PE; Mark J. Farrow PE Due to a troubled economy, trends are likely to continue related to reductions in available construction budgets as well as available supplies of natural resources. Significant construction savings can be achieved at sites underlain by deep expansive clay soils by an improved understanding of the anticipated behavior of expansive clay soils. Two of the most debated design requirements include the following: a.) Soil swell uplift forces on drilled piers; b.) Excavation requirements for slab-on-grade construction. This paper addresses issues related to both of these design requirements as well as a few examples of how the understanding of these issues have reduced construction costs. The first example will be the Grapevine Mills Mall. For this project, two previous geotechnical engineering studies recommended a pier and beam foundation system with structural floors due to deep highly expansive clay soils (including a significant deep seated swell potential due to deep seated swelling below depths of 10 feet). Through a combination of excavation and moisture conditioning of the upper layers of on-site soil, shallow foundations were able to be used for the Grapevine Mills Mall. Other examples will include projects where excavation and moisture conditioning of onsite soils were used for office and retail buildings in combination with either drilled piers or shallow footings as alternatives to deep select fill placement and/or pier supported structural floors.
History and Heritage Military Engineering—A Forerunner to the Civil Engineering Discipline Robert C. Burton PE Here in the United States (as well as many nations around the world) the early military engineers set the stage for the Civil Engineering profession to become entrenched and respected across our great nation. From the early days of the Army Corps of Engineers and the Navy Bureau of Yards & Docks (which later become the Navy Facilities Engineering Command), the history books are filled with military engineers setting the stage for a prosperous future. From design-

This paper will bring this important history lesson to light for our young new engineers. As a Navy Captain (O-6) with 20+ years in the Civil Engineer Corps, I have the personal experience and keen interest in this topic. The Social Responsibility of Engineering Danny L. Kahler PE Recent engineering failures have lead to costly disasters around the world. Many failures may be attributed to engineers, employed within corporations or government organizations, who are exempt from professional regulation or accountability to either the public at large or their respective professional societies. The historical social responsibility of engineers can be traced to the Code of Hammurabi, which established strict disciplinary actions for the negligent practice of law, medicine, and engineering. To be socially responsible in a global market, engineers are in need of an updated, comprehensive, and potentially international system that reasonably assures competence, transparently notifies the public of who is qualified to practice, and hold engineers personally accountable for their work. Loammi Baldwin Sr - Revolutionary War Hero/Civil Engineer Cliff Schexnayder Loammi Baldwin Sr., Revolutionary War hero, became America's first native born civil engineer. Baldwin, the future father of an engineering dynasty, quickly assembled the Woburn militia companies and met the British as they returned from Concord on that fateful morning of April 19, 1775. Years before he had walked eight miles to Harvard so he could listen to Professor John Winthrop's Experimental Philosophy lectures. Following the Revolution there were very few trained engineers in the new Federation. So in 1793 when a group of Medford men, led by James Sullivan, the Attorney General of Massachusetts, were successful in petitioning the General Court of Massachusetts to grant them incorporation for building a canal from the Merrimack River to Boston, Loammi Baldwin became America's first homegrown civil engineer. Baldwin's Middlesex Canal was recognized by ASCE in 1967 as a National Historic Civil Engineering Landmark but success did not come easily.

Houston, Texas. The principal challenges of designing an economical foundation system for twin 26-storey towers orthogonally positioned with two basement levels in the heart of the Medical Center CBD were magnified by the unforeseen underground conditions, adapting a common skin to accommodate both towers, and the potential Harris Bayou flooding. The tallest Houston building on shallow foundations ever built against by a basement supported structure flanked the new facility and formed a broader challenge because of the past differential movement. Larger in space than the world's tallest suburban office building, Williams Tower (formerly Transco Tower) the economy of the reinforced concrete structures focused on combining the temporary retention system with the permanent basement. Classical analysis and Terzaghi Construction Geotechnical Engineering were essential to the successful foundation design.

TEXAS CIVIL ENGINEER drilled piers (up to eight feet diameter) into the rock. The structure has a small shear wall core, columns with post-tensioned flat slab floor system. The floor span has a span of almost 30 feet and an 8.5-thick post-tensioned floor slab was used. The shear wall core is only 30 feet wide. In order to stabilize the building under high wind loads, a 17 foot nine inch deep set of outrigger walls were built (between the 31st and 32nd floors) to connect the core to the exterior columns. Since the tower is very narrow for its height, extensive wind tunnel tests were conducted to obtain wind loads on cladding, base shears and overturning moments, and to reduce the motion perception under high wind loads. A tuned sloshing damper has been provided at the top of the tower. The article describes the engineering and construction of this unique tower.

Post Tensioning of Wood Beams Nic Nitti; Chandrasekhar Putcha PhD Throughout the lifetime of a building it may see differences in its loading conditions than were anticipated in the original design. Additional loading may be added to a structure, such as new mechanical units placed on the roof or hung from beams. In addition, buildings built decades ago were designed under less vigorous building codes. Therefore, often times these buildings will need to be retrofitted and upgraded to meet the additional loading and new codes. Post tensioning of existing wood beams is an efficient and effective method of reinforcing these existing wood members. The main objective of this research work is to analyze a fully loaded wood beam after post tensioning. A comparison will be made between the analysis and design of the post tensioning system, and the actual results from tensioning an existing beam. Existing conditions shall be idealized for analyses by two methods. First by hand through Matrix Methods procedures using a computer-oriented direct stiffness method, and second by using a finite element analysis program for an in depth investigation. The bending moment of the beam before post tensioning shall be found, and then the required amount of tensioning shall be determined through calculations. The required amount of tension is the tension necessary to overcome the loads imposed on the beam. Finally, both the hand calculations and the computer modeled analysis will be compared with data compiled from an actual post tensioned beam. The actual tension applied and the resulting decrease in overall deflection will be compared with those predicted in the calculations.

Civil Engineering Responsibilities in Special Inspection Danny L. Kahler PE; Charles J. Kanapicki PE The International Building Code contains requirements for detailed structural inspection of buildings that are critical for public safety, or exceed a certain threshold for occupancy. These requirements are detailed in Chapter 17, Structural Tests and Special Inspections. This type of activity, the verification that the constructed work conforms to the approved plans and specifications, is part of the practice of engineering as defined by NCEES Model Law and the statutes of most States. However, the implementation of Special Inspection
varies widely across jurisdictions across the country. In some cases, local certification for Special Inspectors allows vocational practitioners to be responsible for this activity, without being licensed as either a Professional Engineer or Registered Architect. The issue of civil engineering responsibility in Special Inspection of critical structures was a factor in the recent half billion dollar controversy involving the Harmon Hotel in Las Vegas. This session will cover some of the history of special inspections, an overview of the responsibilities established within the building code, and its implications on the responsibility of civil engineers to protect the public health, safety, and welfare. This session will not be a detailed description of all of the tasks involved in Special Inspection, but will focus on the larger professional practice issues. Estimation of Wind load on Tall Structures: SPH method; Part: II Ananna Ahmed; Abdullah-Hil-Baki; Munaz Ahmed Noor PhD Popular methods of calculating wind load is Wind tunnel test and FEM. Specification codes have been set to avoid disparity in individual design of same locality. In this two methods, one is extensive and another is expensive. In this research, to eliminating few drawbacks of these methods and providing a visual interpretation of wind flow for the first time, a third method is introduced by using Smooth Particle Hydrodynamics (SPH). SPH is a mesh free Lagrangian method. A model simulation was performed by a SPH based software named SPHysics to calculate the pressure exerted on the structure and to derive a graphical interpretation of wind flow pattern. In the first part of this research, values of pressure at different elevation of the building that actually occurs when wind with certain velocity flows through a tall building are found. Height vs. pressure and velocity vs. pressure graphs are generated which clearly supports the typical proportional relationship between these parameters even with triangular and parabolic variation. The first part of this research was only qualitative and in this part, few limitations of simulations are resolved and one set of values of wind pressure is cross checked with values found from local building code (BNBC’93). In future, with intricate detailing and suitable 3D modeling, authors believe a very user-friendly method can be derived with wide range of applicability, which will introduce a new dimension in this field.
Transportation and Development Institute Innovative Quality Management for Transportation DesignBuild Danny L. Kahler PE The engineering practice models for design–bid–build are well established and documented. However, these same practice methods may not be a good fit for innovative delivery, such as design-build and concession. These delivery types introduce major philosophy changes such as the design and construction quality assurance engineers working for the contractor and total responsibility of the design–builder for quality. Civil engineers will need new practice models of
Settlement of Highway Embankments Constructed with Reclaimed Asphalt Shingles Ali Soleimanbeigi PhD, PE, Tuncer Edil PhD, PE, D.GE Asphalt shingle waste has been identified by Environmental Protection Agency (EPA) as top five priority material for reuse application. While shear strength and hydraulic conductivity of reclaimed asphalt shingles (RAS) are comparable to those of granular materials, significant compressibility is the main issue for use of RAS as structural fill applications. In this study, compressibility of RAS mixed with foundry slag (FS) was investigated to develop design guidelines for use of RAS in construction of highway embankments. Results showed that compressibility is reduced to below allowable limit by increasing granular additives (e.g., FS) to more than 50% by weight of the RAS:FS mixture. The secondary compression index is a power function of stress level indicating that the RAS containing embankment settles at different rates along the height of the embankment. Use of asphalt shingle waste in the construction of highway embankments involving large quantity of materials, will contribute to more sustainable roadway infrastructure. Implementing Federal Requirements for Quality Assurance/Acceptance on Innovative Delivery Projects J. Jeffrey Seiders Jr, PE; Chien-Nan Fu PE; Newel White PE With advances and increased use of innovative project delivery methods for transportation projects, DOTs and contractors have been able to realize the advantages of risk transfer to accelerate schedules, control costs, and improve quality on large complex projects. With experiences on over $5 billion of innovative delivery projects, Raba Kistner Infrastructure (RKI) has served in various design and construction quality roles including Quality Control, Quality Assurance, Independent Assurance, Owner Acceptance/Verification and Independent Engineer. These projects often require the contractor perform the Quality Assurance testing as part of the acceptance decision. In this scenario, the federal regulations require statistical validation of the Contractor Quality Assurance and Owner Quality Acceptance/Verification test results. RKI's broad experiences afforded a very unique and robust perspective on federal requirements compliance. The success of using contractor performed tests starts with merging Quality Assurance and Owner Quality Acceptance/Verification processes, working as one project team. Common to all innovative project delivery methods, communication is paramount to overcome the technical and human element challenges. The culmination of these experiences has repeatedly shown us that implementing the detailed processes needed to achieve statistical validation will require a high level of coordination of the materials engineering and testing personnel at all levels. Beyond the basic requirement of reporting accurate and complete test results, it is essential to maintain the integrity of the test data by using timely reporting and efficient management of the electronic data.
FALL 2012 • VOLUME 82 • NUMBER 4 This paper relates several of these lessons learned and provides a basis for recommendations to modify existing requirements. Risky Business - Managing Owner P3 Project Risk Michael Hasen PE; David Weeks PE; Brett Haggerty PE; James Travis PE P3 projects are diverse and the risk profile for each project is unique. Risk management is an important aspect of both procurement and construction. This paper highlights the varying risk profiles for three projects: (1) a pass through toll project with no maintenance after construction, (2) a designbuild project with 15 years of maintenance after construction, and (3) a concession project with a maximum of 52 years maintenance after construction. The various elements of owner risk will be identified and means to manage risk discussed including the length of maintenance and exposure of public funds such as Highway Trust Fund or TIFIA loan assistance.
Poster Session Proactive Environmental Permitting Strategies for LargeScale Projects Therese M. Baer PE; Rosemary Wyman PG; W. Ryan Metz; Brian K. Reis PE Proactive environmental permitting strategies help identify and resolve environmental issues, while avoiding schedule and budget issues. Proactive permitting strategies require five basic steps: 1) Identify natural/cultural resources, and other permitting considerations. 2) List regulatory requirements and determine their interaction with the project. 3) Perform an environmental impact analysis. 4) Plan to avoid impacts, and plan appropriate mitigation for unavoidable impacts. 5) Coordinate with regulatory agencies throughout the planning process. The design team for the Waller Creek Tunnel Project in Austin, Texas, used this strategy successfully. They suggest others adopt this strategy to improve permitting practices that are typically reactive. Using Infrared Thermography to Detect Water Feature Failure Therese M. Baer PE; Michael Peatross RRO, LEED AP Baer Engineering and Environmental Consulting, Inc. used infrared thermography to detect structural deficiency of the water features at the Austin–Bergstrom International Airport. The infrared thermography measured the distribution of radiant thermal energy emitted from each water feature surface and converted this to a surface thermogram. The thermal capacity of water exceeds that of common building materials; therefore, water is slower to absorb and radiate heat than most common building materials. This differential, visible on the thermogram, allowed us to identify temperature anomalies, indicating structural deficiencies. The application of infrared thermography in evaluating existing structures for defects and efficiency provides a useful, cost-effective, and nondestructive method for civil engineering.

Good Luck!
Texas Section 2012 Infrastructure Report Card Update By David Calabuig PE, 2012 Infrastructure Report Card Committee Chair
S
usan K. Roth Consulting, LLC has updated all 13 infrastructure categories of the 2012 Report Card for Texas Infrastructure (roads and highways; bridges; transit; aviation; schools; drinking water; wastewater; dams; solid waste; hazardous waste; navigable waterways; flood control and energy).
www.texasce.org
The consultant contacted many state and federal agencies having jurisdiction over the 13 categories of the Report Card, requesting they provide updated information since these categories were last reviewed in 2004 or 2008. The consultant then updated the fact sheets for the 13 categories.
30
The Infrastructure Report Card Committee (IRCC) reviewed and finalized each of the 13 updated fact sheets. The IRCC then presented them to an independent panel that was tasked with giving each infrastructure category a grade ranging from A to F. The IRCC has produced a pocket size Report Card that will be distributed to our state legislators prior to the Texas 83rd Legislative Session (which begins January 8, 2013) and to ASCE Texas Section members attending the Fall 2012 Conference in Forth Worth November 7–10. The IRCC will release the 2012 Report Card for Texas Infrastructure at a press conference on November 8 at the Fall 2012 Conference. Following the press conference, a special session will present the findings in the Report Card in greater detail and include a panel discussion with representatives from several agencies that provided information.

Region 6 Governor’s Update By Martha F. Juch PE CFM, Region 6 Society Director Region 6 represents three Sections (Oklahoma, New Mexico and Texas), 20 Branches, and 18 Student Chapters. We are one of the largest Regions in terms of populations, and we are definitely one of the most complex in terms of the number of geographic units represented.
ASCE Board of Direction Meeting in New York City, July 2012 The ASCE Board of Direction met in New York City on July 19 and 20, 2012. The Directors were briefed on the status of our three Strategic Initiatives: Raise the Bar, Infrastructure and Sustainability. The Raise the Bar initiative is currently focused on gaining support for the concept of advanced education for Professional Engineers by conversations with other engineering professional societies and targeted state Board of Registrations. It's a slow process, but ASCE leadership is committed to pushing this initiative forward. The Infrastructure initiative is successfully completing the fourth of the Failure to Act Economic Studies and is focused on the 2013 Report Card for America's Infrastructure, which will have many new features, including an electronic app. The Sustainability initiative has seen the formation of the Institute of Sustainable Infrastructure (ISI), the development of the project sustainability rating tool, and the role-out of the first training module for the Sustainable Infrastructure Certification Program. ASCE is committed to taking a leadership role in certification of engineers in the design of sustainable infrastructure and is excited about the progress of this initiative. To address a need to streamline the twenty three committees reporting to the Board, the Board reviewed the work of the Task Committee on Committee Restructuring and approved the changes to the Society's Bylaws to remove the existing standing Board Committees and create four standing Board Committees and five standing Society Committees effective October 20, 2012. Functions currently being addressed by existing committees will be defined under these committees and the reorganized constituent committees which report through the Society Committees. Additionally, the Board approved the formation of a Strategic Initiative Committee, approved changes to the Society's Rules of Policy and Procedure, and established requirements for committee reporting, periodic review of committee structure, term limits for committee members, and the committee appointment process.
www.texasce.org
The Board also reviewed the Society's financial status and the proposed budget for fiscal 2013 with operating revenue of $49,446,000 and operating expense of $49,656,000. Although the staff, senior leadership, Programs Committee and Finance Committee have spent many hours reducing operating expenses and programs as much as possible, revenues will not cover expenses and the Board reluctantly voted to increase membership dues by $15. This will cover losses experienced by not adjusting dues consistently in the past to keep up with inflation, and, together with funds from the reserves, will enable the Society to continue to provide high quality services to its members while staying aggressively engaged with the three Strategic Initiatives and in modernizing Publications and Continuing Education. To address the ageing of our membership base, the Board also increased the requirement for Life Members to have paid dues for at least 35 years and increased the Life Member Service Fee to $50 per year or a one-time fee of $500.
32
This is just a brief summary of a very intense Board meeting. I encourage you to go to the ASCE website to read about the Strategic Initiatives and other items considered by the Board. The Region 6 Board of Governors met with the Oklahoma Section on September 7, 2012 in Stillwater, OK, and the ASCE Board of Direction will meet next at the annual meeting in Montreal, Canada on October 16–17. All meetings are open to the membership, so I encourage you to attend if you are available. If you need additional information on any of these topics, please contact me, one of the Region 6 Governors, or the Texas Section office. Martha F. Juch PE CFM, Region 6 Director 2010–2013, mfjuch@austin.rr.com

Are you STEM enough? By Martin J. Pflanz PE Vice President Educational
The U.S. has been ranked 52nd in "quality of mathematics and science education" among the other global countries. Not the Olympic-e esque placing you expect, is it?
L
ast month I had the opportunity to attend the National STEM Solutions Summit in Dallas with 1,500 other industry professionals, education and STEM focused non-profit organizations. The primary focus of the event was to build a solution around the critical need to rapidly grow the skilled workforce required to sustain America. During the summit, large industries such as AT&T, Boeing, Dell, Wells Fargo and others shared stories of change throughout their communities - some really amazing projects! There was also clear evidence presented on the growth of STEM academy schools from the elementary level to high school that did not exist two years ago.
Infographic courtesy of Knewton. To see the full graphic, visit www.knewton.com/stem-education/.
The problem is that as Baby Boomers retire, the lack of STEM graduates to replace them leads to a drop in a skilled workforce. Meanwhile, a demand for that skilled workforce continues to grow. ASCE's Infrastructure Report Card for the nation confirms this critical need. Check it out at: http://www.infrastructurereportcard.org.

After speaking with many attendees, the responses were clear: "We need engineers to get involved!" and "Where are the engineers?" There is definite pressure for volunteers and mentors to get involved and help nurture the professionals of tomorrow. Each of you, as a member of ASCE, is a part of the solution to this serious problem. The good news is that there are several great, well-organized programs in which you can get involved with right now!

ASCE Texas Section Executive Committee Meeting Summary
T
he Executive Committee met on June 30, 2012 from 8:30 AM to 2:00 PM at the Homewood Suites, Bedford, Texas and by webcast teleconference on August 2, 2012, from 4:00 PM to 5:30 PM. June 30, 2012: Guests in Bedford included the Fall 2012 Conference host committee representatives Mark N. Assaad PE and Curtis B. Beitel PE, Spring 2013 Conference host committee representative and VP Tech Nominee John D. Garcia PE, Region 6 Governor Nancy S. Cline PE, Director at Large Nominee Brett A. Pope PE, President Elect Nominee Tim C. Newton PE and Centennial Event Planning Assistant Paula J. Rigling. The Executive Committee approved the final budget, registration form and promotional items for the Fall 2012 Conference in Fort Worth. This has become a three-in-one conference with the participation of the ASCE Construction Institute (CI) and the International Conference for Sustainable Design, Engineering, & Construction (ICSDEC). ASCE's PR University is being offered, in advance of the 2012 Texas Infrastructure Report Card release during the conference. The finals of the North Texas Land/Water Sustainability Forum Low Impact Development (LID) Design Competition will also be held. The members were reminded of the revenue sharing arrangements for this conference: any profit made by the conference will be divided with the Fort Worth Branch retaining 40% and the Texas Section and CI receiving 30% each. The Branch is further protected with a cap on its maximum financial responsibility if the conference shows a loss.
www.texasce.org
Promotional items for the Spring 2013 Conference in Corpus Christi were approved; action on the budget and registration form were postponed pending input from the Centennial Planning Committee. Due to the earlier than normal conference dates the registration form and other promotional items for the TCE magazine will be in the winter 2012 issue.
34
The Executive Committee approved both the budget and sponsorship program for the Centennial. Sponsorships from corporate and individual donors are targeted for $270,000 with an additional $25,000 to be raised from grants and merchandise sales. All revenue is expected to be applied to Centennial projects and programs. Extensive recognition of corporate sponsors is planned throughout the centennial year. The Executive committee endorsed the recommendation that both the Margaret Hunt Hill Bridge in Dallas and the Hamilton Pool Restoration Project west of Austin receive the 2012 Texas OCEA Award to be presented at the spring con-
ference in Corpus Christi with recognition at the fall conference in Dallas. Nancy Cline, as chair of the Section Meetings' Format Change Task Committee, provided a verbal report on the committee. Volunteers are stepping up and more are welcome to join this effort. A recommendation is planned for the Board in the fall. Centennial Celebration Planning progress was reported by Paula Rigling. Ideas for centennial merchandise were solicited and the library banners project was discussed. Other projects being developed at this time are the Geocaching Challenge, the legislative day at the capital and media event for the infrastructure report card, and the "Day without civil engineers" video contest for students. President Elect Furlong outlined his goals for the coming year: support the Centennial Celebration, and focus on ASCE's sustainability, infrastructure and "Raise the Bar" initiatives. VP Professional Verma presented a plan to develop the Community Involvement initiative identified by the Section's Strategic Plan. After discussion the proposal will assign the oversight of a Community Involvement program to the VP Professional who will coordinate directly with the Branch presidents to develop local programs. The preliminary 2012-2013 Operating Budget was presented. Discussion centered on the interim report from the auditor and the contract for publishing the TCE magazine which expires September 30. A new writer for the centennial history book has been identified after the original author resigned from the project. August 2, 2012: The Spring 2013 Conference budget and registration form were revised and approved as was the 2012 Texas Excellence in Journalism Award, this pending no further nominations being received before August 31. Treasurer Matocha opened discussion on transferring some of the Section's mutual funds to new accounts. The Budget Finance Committee will meet to explore this further. A final audit report and progress on TCE collections by the end of September was requested with the Executive Committee reconvening by webcast in early October to review and vote on endorsement of the 2012-2013 Operating Budget. The recommendation to continue publication of the TCE magazine with the current publisher next year was received favorably after some discussion because of the perceived advantage of staying with a familiar provider during the centennial year and as the TCE transitions to a digital edition. Respectfully submitted, Board Secretary Elizabeth Greenwood

Physical Security of Design– Part IV By Donald E. Willhouse PE F.ASCE Chair, Texas Section Infrastructure and Security Committee
T
he modern world is not the one in which many of us grew to adulthood. Today we have a world-wide problem with domestic and international terrorism that threatens our way of life. This has been demonstrated in many venues, the most obvious being the attack on the World Trade Center on 9/11. Let's look at the complete project management plan. First, we do a background check on the engineers (and others) designing or having access to plans for a public building, facility, or some part of the infrastructure. The reason for this is to weed out anyone who has a criminal background or to try to detect someone on a law enforcement watch list. One city in Texas a few years ago had an engineer (PE with a lapsed license) on staff charged in a federal indictment for terrorist activities. The design should have the level of physical security measures necessary to protect the facility or delay criminal or terrorist activity until law enforcement or security can respond. Barriers may be a combination of readily seen obstacles or may be camouflaged so that they may not be easily bypassed. They may be part of the landscape design as well. All barriers to a facility should have passive and active detection systems for observation to ensure the physical security of the facility. The level of protection is based on the possible threat and the importance of the facility to the local population. Finally, the computer operating systems need to be protected from intrusion and access limited to those few essential people. A well-known case is the recent computer attack on the new nuclear facility in Iran. Computers are used to run many of the environmental systems at a facility as well as the energy resource needed to operate. They need to have tightly controlled firewalls and access whether they are internal to the facility or access is allowed from offsite to manage a system, such as the Heating, Ventilation, Air Conditioning (HVAC) system.
www.texasce.org
The security for the designed facility should be a part of the design and approved, or disapproved, by the building owner as a part of the contract. Today, we must think outside the box and be aware of threats as noted by law enforcement. This is the next step in protecting the health, safety, and welfare of the public.

Fort Worth: From “Panther City” to “Cowtown” an excerpt from a historical impression by Travis N. Attanasio PE CFM The Fort Worth Stockyards hold a distinction that not too many others can claim: it created a city.
Early History:
Fort Worth began as a small military outpost in 1849 to protect settlers from attacks during the Mexican War. When military operations ended, the barracks were taken over by businesses, which would serve the tiny community and travelling cowboys on the Chisholm Trail. In 1875, flooding in the Trinity River drove a panther into the streets where it wandered at its leisure. Seeing the chance to poke fun at Fort Worth the Dallas Herald published an article by a former resident who claimed "things were so quiet, I saw a panther asleep on Main Street, undisturbed by the rush of men or the hum of trade." The Fort Worth Democrat responded to the insult by changing the paper's motto to "Where the Panther Laid Down." The residents of Fort Worth then nicknamed Fort Worth as "Panther City."
Cattle grazing on a Texas ranch.
The Stockyards Build a City:
Fort Worth was the last stop on the Chisholm Trail before cattle drivers crossed into Indian Territory. Texans started calling it "Cowtown" when cattle-drivers began herding cattle from South Texas northward, stopping for supplies and spending time gambling in the saloons that lined the town streets. The railroad came to Fort Worth in 1876, and replaced traditional cattle drives. Fort Worth businessmen made plans for stockyards and slaughterhouses, which would put it permanently on the map as a center for the cattle industry. The first such company operated without a profit for three years due in part to a quick turnaround of livestock from higher prices in the north. In 1892 the owners of the company invited a capitalist to visit with the hope of investment. When the investor showed the pens were brimming full of cattle and the investor decided that Fort Worth represented a good market and incorporated the Fort Worth Stock Yards Company. In 1896 the company began a fat-stock show that has survived to the present as one of the largest livestock shows in the nation. It soon became apparent that instead of shipping to other markets to process the cattle, it would be much more desirable to keep more of the business in Fort Worth by having local packing plants. A search began to lure major meatpackers to the City. In 1900, the two largest meatpacking companies, Armour & Co. and Swift & Co. were persuaded to build plants adjacent to the Stockyards. While construction was underway, the Fort Worth Stock Yards Company incorporated much of the area north of the river adjacent to the Stockyards as North Fort Worth. In 1909 the City of Fort Worth annexed North Fort Worth, with the exception of the Stockyards and the packing house property. Fearing that the City of Fort Worth would try to annex more of the area, Niles City was incorporated in February 1911. The town was called "the richest little city in the state of Texas" because of the high value of several corporations within its boundaries which were valued at over $12 million roughly equating to $277 million today.

In 1921, the Texas legislature passed a bill which allowed any city with a population of more than 50,000 to take any adjacent territory that did not contain a town of more than 2,000 inhabitants. This bill enabled Fort Worth to annex Niles City. To block annexation, Niles extended its city limits and gained the needed population. However, a second bill was passed that raised the population needed to block annexation to 5,000. In spite of litigation to block annexation, Niles City became a part of Fort Worth in 1923.

As one technological innovation in the railroads brought success to the stockyards, another would contribute to the decline. The rise of the trucking industry on the newly paved roads after World War II lowered operating costs and greater flexibility, and the advantage that railroads had in bulk shipping was lost. Both Armour and Swift had huge outdated plants that were straddled with rising expenses. Armour was the first to close their Fort Worth plant in 1962 with Swift closing in 1971. Today the Fort Worth Stockyards Historic District is one of Texas' most popular tourist destinations. Would you like to know more?
