ARCHITECTURAL FACADES UNLIMITED Sherman Clay Building Restoration
211 Sutter Street, San Francisco, California Architectural Precast Association Awards Architectural Facades Unlimited in two catagories.
• GFRC Excellence • Craftsmanship JURY COMMENTS: Fantastically detailed renovation of a classical building using GFRC. The castings matched the original details and were able to do so without any noticeable transitions. The elegance of the original design is restored to this treasure of a building.
ARCHITECTURAL FACADES UNLIMITED RESTORATION CASE STUDY: Sherman Clay Building is a turn of the 20th century 18 story building. Exterior facade consists of ornamental terra cotta spandrels, jambs, sills, fluted and tapered columns, Doric capitols, ornamental shell parapet castings. Using the original materials, in most cases would make restoration costs prohibitive. The use of GFRC for restoration allows for the historical preservation of our nations landmarks.
Water intrusion at the top four floors created severe corrosion to the structural steel members and to the terra-cotta anchors weakening the structure. Architectural Facades performed selective removal of several of the original terra-cotta castings that were then repaired and readied for the mold making process. Polyurethane rubber molds were made over the high quality terra-cotta castings - columns, capitol & base, rosettes, shell and facial ornaments, dentals, egg and dart moldings to replicate to exact detail of original terra-cotta castings.
GREEN AND SUSTAINABLE
Responsible - Using Lehigh White Portland Limestone Cement (PLC) is an environmentally responsible choice. Production of this earth friendly cement generates about 10% less CO2 than other Portland Cements, while still delivering the consistency, versatility and performance Lehigh customers, like Architectural Facades Unlimited, come to expect.
The GFRC system reduces onethird of original terra-cotta weight. Light weight GFRC castings are anchored to a new metal stud steel framing system designed by Architectural Facades. The anchorage design for GFRC units are flexible allowing for thermal and seismic movement.
Green Building - Lehigh White Portland Cement allows for the production of a more sustainable concrete product for owners and designers who want a green option in architectural concrete products.
RESTORATION TEAM Architectural Facades Unlimited, Inc.
Architectural Precast GFRC • 600 East Luchessa Ave., Gilroy, CA 95020
1,800 pieces were cast for this project.
The challenge in this project is to produce castings with the exact color, shape, and finish of the original terra-cotta castings. Architectural Facades Unlimited’s creation of the perfect GFRC color match and mix design to the original terra-cotta was accomplished in eight sample runs. Lehigh White Portland Limestone cement, is a key component in Architectural Facades Unlimited’s achievement of batch color and texture consistency throughout this project. The contractor applied a glaze and seal coating over the GFRC units. The final appearance of the GFRC and Terra-Cotta is indistinguishable.

Through the Lens of Trade Shows
Cory Sekine-Pettite, editor To make comments or suggestions, send e-mail to cory@lionhrtpub.com.
In the world of B2B and trade publications such as ours, editors and publishers often gauge the health of the industries they cover through the lens of trade shows. We look at the number of attendees and exhibit hall vendors, and deduce from those figures if our industry is doing well. Mind you, these aren’t scientific studies, but the determinations we make generally are accurate. Sometimes, however, our instincts can be wrong. Case in point: Earlier this year, I attended a large, annual trade show for the construction industry. Throughout my week there, I noticed that the show seemed both smaller in scale and hosted fewer attendees than in years past. Other attendees and exhibitors confirmed my feelings. Could it be true? Could all the industry reports and forecasts be wrong? Is the construction industry really hurting? Well, no. In conversation with one vendor, he and I determined that attendance was down at this trade show—and probably others—because people are actually busy. They’re working and don’t have the time to travel. Imagine that! In fact, according to Dodge Data & Analytics, most of the leading U.S. metropolitan areas for commercial and multifamily construction starts showed substantial gains in 2016 compared to the previous year. Construction starts in these categories were valued at $186.3 billion, up 7 percent from 2015. So while this bodes well for the industry as a whole, it may not be the best news for trade show attendance. (Not to mention the projected loss in skilled labor, but that’s a topic

New FAA Rules Impacting the Use of Drones Over Construction Sites
By George Jiang, attorney
Eckert Seamans Cherin & Mellott LLC
About the author: George Jiang focuses his practice on commercial litigation and construction matters. He also possesses experience counseling clients regarding environmental matters and white-collar criminal defense. Before joining Eckert Seamans, George served as a judicial law clerk for the Hon. Nora Barry Fischer of the U.S. District Court for the Western District of Pennsylvania, and for the Hon. Brian L. Owsley of the U.S. District Court for the Southern District of Texas. In addition, he served as executive articles editor for the Journal of Legislation while he attended law school.
Recent innovations in small, unmanned aircraft (more popularly known as “drones”) have given construction contractors the ability to cheaply and efficiently conduct site surveys, inspect otherwise inaccessible areas, monitor progress, aid in the early identification of potential deficiencies, and ensure that the project is completed on time and within budget. In response to the surging popularity in the commercial operation of drones, the FAA implemented new rules (1) addressing who is qualified to fly a drone for commercial purposes and (2) imposing operational limitations on the use of a drone. Accordingly, contractors that operate drones should be aware of the potential impact these rules may have on the way that drones can be used on construction sites. The most significant constraint imposed by the new FAA rules is the requirement that all commercial drone operators must either obtain a remote pilot certificate or be directly supervised by a person who has obtained the certification. To obtain a remote pilot certificate, an applicant must pass an aeronautical knowledge test as well as a background check. Unlike the manned aircraft certification process, flight training is not necessary, and a practical examination in unmanned aircraft flight proficiency will not be administered. Applicants with an existing pilot certificate for manned aircraft can obtain a remote pilot certificate if they have completed a flight review within the past two years and finish an online training course. Commercial drone operators also must comply with new restrictions on how and when drones may be used. In particular, those considering using drones on construction sites should be aware that the new FAA rules prohibit a drone from being flown: • Outside of the operator’s visual line of sight • When visibility is less than three miles • Less than 500 feet below a cloud or within 2,000 feet horizontally from a cloud • At night • Directly over people not directly participating in the drone’s operation • Higher than 400 feet above either ground level or a structure, whichever is higher • Without permission in controlled airspace In addition, each drone must weigh less than 55 pounds, regardless of whether it is carrying a pay-

load. The FAA also requires all commercial drones to be registered and marked. The practical effect of the FAA’s new regulations for drone operations over construction sites can be significant. The visual line of sight requirement may limit the most potentially useful applications for drones, such as using a drone to inspect an inaccessible area from a vantage point that also is beyond the operator’s line of sight. It also may be impractical to use a drone on a busy site because of the risk that it will be flown above other people working on the premises, and the regulations make no exception for sites where people are required to wear hardhats. Furthermore, drones cannot participate in nighttime construction activities, and operators must be aware of whether the site is situated below or near restricted airspace, such as airports or other sensitive areas. In areas with inclement weather or low cloud cover, drone operations may effectively be grounded, even though the construction site itself is unaffected and visible to the drone pilot. Fortunately, all of the significant operational restrictions listed above can be waived by applying for a certificate of waiver demonstrating that the proposed drone operation can be safely conducted. This request for a certificate of waiver must contain a complete description of the proposed operation and justification for why the operation can be conducted safely. Drone operators seeking a waiver should therefore consider offering to take specific precautions depending on the type of waiver requested. For example, a request for a waiver of the visual line of sight restriction could include a statement that the drone operator will be using reliable first-person-view technology to maintain full awareness of the drone’s location and surroundings. Similarly, a request for waiver of the restriction against operating drones directly overhead other people is more likely to be granted if it is accompanied by assurances that all personnel on the site will be forewarned about drone activities and are required to wear hardhats during the flight. As the benefits of using drones for construction projects become increasingly clear, their presence at work sites will become the norm rather than the exception. Contractors should be mindful of any potential FAA restrictions that apply to any planned drone flights and make sure to apply for the proper waivers given the particular project at hand. wMD Materials • Technolog y • Trends

2017 Brick Trends Show Whites, Thin Brick and Rustic Textures Hot trends in fired clay brick show preferences for whites, greys and lighter colors, thin brick, rustic/weathered textures, and larger brick sizes. Brick Industry Association (BIA) member manufacturers around the country report that residential and commercial trends include whites, light greys, ivories, rough-hewn textures, glazed brick, and larger brick sizes. “As an abundant natural resource made in America, brick options continue to evolve for virtually endless aesthetic flexibility,” said Ray Leonhard, BIA’s president and CEO. “Our whites, ivories, and light greys are being requested more and more, either as a full project or to complement a darker, more traditional brick on a project,” said Dawn Henning, director of marketing and retail sales, General Shale. “Secondly, thin brick is probably the biggest trend that is catching on everywhere. I get requests from all over the world for our thin brick.” In addition to greys and creamy neutrals as a base color, Triangle Brick adds modern farmhouses and bungalows pairing brick with subtle exterior tones. Larger brick sizes also are trending, according to Stephanie Kennedy, marketing manager at Redland Brick Inc., The Belden Brick Company. The company’s Cushwa plant (Williamsport, Md.) now offers Molded Roman face brick with longer

and more linear dimensions than those of standard modern brick. Acme Brick Company echoes trending colors, textures and sizes. “We are still seeing a trend to lighter colors or white-washed looking brick,” said John Brewer, Acme’s Central Texas regional sales manager. “Residentially, King Size brick is still the largest in demand,” he said. “Everyone wants a very rustic, beat-up finish.” The Belden Brick Company reports that thin brick and glazed brick also continue to rise, along with clay pavers in diverse sizes. “Thin brick continues to sell,” said Mark Britko, Belden’s manager, strategic markets, whose company has expanded its glazed brick offerings and capabilities. Trends also include clay paver patterns using other sizes with the normal 4 X 8s. wMD

Health & Wellness Center Benefits from State-of-the-Art Thin Stone System
Project: Virtua Health and Wellness Center, Washington Township, N.J.
Architect: HGA Architects, Milwaukee, Wis.
Product: ARRIS-clip Renaissance Units, Custom Color
The healthcare industry is about more than helping the sick or injured get better; it also involves providing positive environments for healing and wellness. Building designers create healthcare facilities with user experience top-of-mind and seek high performance masonry products to execute their modern, inviting designs. Virtua Health & Wellness Center in Washington Township, N.J., is a 300,000-square-foot facility providing a variety of services to help people get well and stay well. Patients have easy access to physician offices, specialty services such as sameday surgery, a pharmacy, a community meeting space, a retail shop and more.

HGA Architects in Milwaukee, Wis., created state-of-theart, healthy designs for Virtua Health & Wellness Center; in particular, for the building’s exterior. These designs called for ARRIS-clip Renaissance® units from Arriscraft to perform as a major part of the exterior façade to achieve their overall design vision. Several Virtua group properties feature Arriscraft thin stone. According to the manufacturer, Arriscraft delivers uniform color and format, for a consistent design approach across numerous projects—even if they are built years apart. Due to the deep stone soffits and the large spans between columns, there were few options available to support a traditional 4” thick unit masonry veneer façade. This left only one option for the designers—curtain wall construction. This led to 34,000 square feet of ARRIS-clip Renaissance Units being specified. The use of the lighter ARRISclip units allowed for lighter structure resulting in significant cost savings and greater design flexibility. Materials • Technolog y • Trends
Project Highlights: • 34,000 sq. ft. of ARRIS-clip Renaissance units Smooth finish. Custom color. • The first of four Virtua facility buildings on three separate campuses with 180,000 square feet of ARRIS-clip Renaissance units being specified. • Joints were finished with backer-rod and silicone sealant. • Return Corner Units were utilized at the corners of the building. • The suspended stone soffits were critical to the design intent so that stone appeared to be “floating” over the store front windows below. • Since the joints were not mortared, the use of the ARRIS-clip.

“The project began as a renovation plan to address the maintenance and repairs recommendations from a previous Façade Inspection & Safety Program report, required by the New York City Department of Buildings,” explained CTA Principal G. Douglas Cutsogeorge, AIA. “While preparing for the renovations, CTA performed a new survey that discovered additional required repairs. Our team’s report also outlined long-term facility maintenance and upgrade needs. CTA, in collaboration with MHHC, then developed the final list of the necessary work that optimized the budget, while addressing the short- and long-term safety and physical plant operational needs,” he added. The CTA team, which also included Senior Project Manager Frank Scanlon, AIA, and Designer and Construction Administrator Ana Ribeiro, designed the repairs program and served as the construction administrator for the project. Goldstein Associates Consulting Engineers, DPC (GACE) was the structural engineer.
The project repaired 560,000 square feet of façades and 80,500 square feet of roofs. The renovations included repairs to and repointing of the brick façades that addressed spalling and other weather damage; replacement and repairs of deteriorated and delaminated metal-clad blue stone window sills; renovations to selective flashings, lintels, and concrete balconies and rails; gutter and scupper drain repairs; waterproofing of roofs; replacement of all roof rails; and repairs to rooftop elevator bulkheads. As part of repairs to the roofs, the crews installed Siplast adhesive bitumen membrane waterproofing system on all six buildings. Brend construction crews used Glen Gery 4HB and 47HB jumbo size brick with Glen Gery G-302 mortar color to replace damaged brick and complete repointing. The roof drains are cast iron, model 1010C; and scupper drains are cast iron, model 1510T; both by Jay R. Smith Mfg. Co. Brend Renovation fabricated copper bulkhead gutters and downspouts. wMD

Decorative Concrete Brings Hockey Imagery to Life at Boston Bruins Practice Facility When the Warrior Ice Arena in Boston was built, the architect wanted to bring the imagery of hockey from the interior to the exterior of the complex. With a landmark 68-foot-high hockey stick, the new 75,000-square-foot practice complex of the Boston Bruins hockey team includes an ice rink with seating for 660 fans, a lobby featuring displays of Bruins accomplishments, a modern locker suite, and team lounge and expansive training and weight rooms. Aggregate Industries US (AIUS), a subsidiary of LafargeHolcim Ltd., designed and developed the product that allowed the vision to come to life. To achieve the aesthetic and LEED-certification goals of the project, AIUS created custom-designed mixes of its Artevia brand of decorative concretes that contained unique colors, aggregates and textures, as well as treatments to reduce the urban heat island effect. The Warrior Ice Arena hardscape was awarded the Scofield Decorative Concrete Award during the 2017 World of Concrete show in Las Vegas, Nevada for its creative and sustainable sidewalks and courtyards. “We’re proud to have played a part of this project which, for Boston, is closely tied to our passion for sports,” said René Marais, Ready Mix sales manager for the Northeast Region of AIUS. “The hockey imagery concepts for the arena’s main entrance were very detailed and creative. For example, the curvature lines by the hockey stick reflect the lines a player makes when he cuts hard on the ice, and the additional exposed white

stones illustrate ice shavings kicked over by the skating blade.” To achieve the design goals for the hardscape, AIUS developed Artevia Color and Artevia Exposed samples with white and gray cement. The specialized concrete mix incorporated an integral coloring admixture from L. M. Scofield Company to create vibrant solar-reflective colors that conform to LEED 2009 requirements for reducing the urban heat island effect. This cool pavement technology helps keep concrete temperatures lower and provides a high solar reflective index value that qualifies the arena for a credit under the sustainable sites section of LEED. AIUS also collaborated with Massachusettsbased Triad Associates, Inc. to produce mockup panels to ensure alignment with the design the customer intended. Due to uniform aesthetics and consistency, the finished decorative hardscape included Artevia Color and Artevia Exposed aggregate concretes, which combined design flexibility and strong visual appeal with low maintenance and durability. The Artevia Color concrete, with onyx black and custom gray alternating strips, was placed at street level, while the Artevia Exposed concrete, with colored stones and glass, was used for the elevated 2,000-square-foot courtyard. “The vibrant color and textured effects of our Artevia concrete enabled the architects to create visually stimulating and architecturally exceptional hardscape that is built to last,” commented Marais. “All this landscaping creativity helps make the Warrior Ice Arena a unique, desirable, and a pleasant place to visit and watch Boston Bruins hockey.” wMD Materials • Technolog y • Trends

FLASHING:
RULES NEVER TO BE BROKEN By Steven Fechino, Engineering and Construction Manager, Mortar Net Solutions
THE MASONRY INDUSTRY IS A PROUD GROUP OF PROFESSIONALS who build extraordinarily durable structures using timehonored techniques that have spanned generations. Discipline and mentoring are the keys to learning the rules that make up the complex trade. As with all things, masonry has rules that will and will not change over time. • Rule No. 1—Masons get paid for what they lay on the wall, not for effort. • Rule No. 2—Completing a job correctly will cost the mason four times more than doing it correctly the first time: One: removal of defective work. Two: replacement of defective work. Three and four: the two jobs that were not completed while the repair work was being performed. • Rule No. 3—A wall without properly completed flashing has a high chance of leaking, while a wall that is flashed correctly has almost no chance of leaking. Now let’s address some rules that are changing. Sealants and flashing technology have recently seen some positive process changes. Products designed to improve the workmanship and quality—compared to what has been available in the past—are now available to both residential and commercial masonry contractors.

MATERIALS | FLASHING For example, new sealants, flashing fabrics, membranes, and composites give masonry and roofing contractors better options to serve their building owners. SEALANTS Early in my career, prior to the sealants that had evolved into what we see used today, bituminous mastics were commonly used to lap flashings, patch around dowels, and seal wall penetrations. Bituminous mastics, when used now, should be checked for compatibility with today’s polymer-based flashing membranes and components. It is typically the responsibility of the manufacturer to determine the compatibility between sealants and other wall components. Simply call the manufacturer and ask. Once the question is answered, it is common to request a letter stating the status of approval or disapproval of the product. Sealants fall into several general categories depending on chemical make-up and formulations by the individual manufacturers. The characteristics listed in this article are based on a wide range of chemical formulations and not specific products, with the understanding that each product can be formulated to achieve different results. Specialty conditions that exist under difficult jobsite restrictions can in in some cases be formulated to offer longer or shorter tack times, more forgiving installation temperatures or cure ranges, as well as abilities to adhere to products that exhibit higher-than-standard surface energy ratings. Butyl
[BELOW] Mortar Net butyl sealant
Developed in 1937, butyl has had a long run in the construction industry. A product that has been around for that long either delivers consistent performance or it does not stay active within an industry. Butyl is successful primarily due to its adaptability to the needs of the roofing and masonry industries. It is an uncured synthetic rubber and is available in sealant tube form as well as convenient tape rolls. It is typically more economical for the contractor to use in the correct application than some of the other sealants on the market. When making a flashing lap or sealing around dowels, butyl is a smart choice. However, it should not be used for general joint sealing, expansion joints or any exposed joints, as this material remains mostly in a “tacky” state throughout its life. Butyl is compatible with today’s polyvinyl chlorides (PVC), thermoplastic polyolefin (TPO), ethylene propylene diene monomer (EPDM), laminated copper fabrics, and most rubberized asphalts (RA) with excellent adhesion to all of these products. Polyurethanes
Polyurethane elastomeric sealants are the sealant of choice by many architects and specifiers for masonry construction because they provide quality expansion, control, jamb and head joints found in masonry-to-masonry and masonry-to-dissimilar material joints. Polyurethanes typically are one- or two-part sealants that have a large variance in tack time, and they offer a wide range of colors. Polyurethanes do not perform well as a lap sealant with many of today’s flexible flashing membranes, as the high surface energy ratings will not allow for anything but a very short-term adhesion. Polyurethanes offer a life span ranging from six to 10 years, depending on exposure and geographical location. Their working temperature 18 |

Polyethers are modified silicones that have the gunnability of silicone and the best characteristics of polyurethanes when installed within the proper temperature range. is between 40 and 95 degrees Fahrenheit, a range that is truly within the useable “gunnable” range for the product. Single-part polyurethane elastomerics typically are moisture cured. Moisture curing begins when the material is released from the packaging tube in a viscous form and reacts with the humidity. Two-component sealants begin as separate, individually packaged products that are mixed thoroughly just before application. Components consist of a base, an activator (sometimes called a hardener), and an optional color pack. The product can be applied several different ways, but the most common ways are to use a bulk gun or a knife—equally important methods depending on the location of the joint to be sealed. Curing begins immediately once the materials have been combined, but tack free and cure times are based on the formulation, and individual product technical data sheets will provide a range of expected cure times. Modified Polyether (Polyether)
Modified polyethers have become a new option in the joint sealant and flashing industry. Polyethers are modified silicones that have the gunnability of silicone and the best characteristics of polyurethanes when installed within the proper temperature range. Polyethers do not migrate oils into porous masonry so they won’t cause staining, and they can be installed in harsh climates at temperatures down to 15 degrees Fahrenheit. With low VOCs and an available quick, tack-free time, polyethers could one day replace today’s polyurethanes because of superior joint material performance and their ability to bond to a wide variety of membranes and substrates. Polyether used with a primer will seal thermoplastic polyolifins with excellent results and can replace heat welding when necessary to meet installation restrictions. FLASHINGS Flashings have seen the biggest change in the market during the last few years with the introduction of time-tested and proven roofing industry products into the masonry industry. Copper Laminate
The tried-and-true copper laminate we all used for years still is on the market, and two manufacturers have made their products much more durable and desirable by laminating reinforced fabrics on both sides of the copper. One of the manufacturers utilizes a fiberglass mesh and the other offers a polymer fabric. These products are durable, nearly impossible to cut with a trowel, and as good a material as any that can be found on the market. They are premium flashing materials that will perform well for years to come. Many of the copper laminates of today do not contain asphalt as a binder, making them compatible with most building products. w w w.masonr ydesignmaga zine.com

MATERIALS | FLASHING
Modern PVCs stay flexible and will not break down and become brittle, which would allow cracks and create leaks.
Rubberized Asphalt
Rubberized asphalt is the most common flashing on the market today, with several major brands offering products in the United States. Commonly installed “Sticky Back” rubberized asphalt is a good, stable material that performs well when installed properly. Primers are sold by some manufacturers as part of every application, and other companies will allow the omission of the primer if the membrane is installed with a termination bar. Installation details for this membrane should be discussed with the project contractor and manufacturer prior to installation. It is critical that the mason contractor read the fine print for each product, as warranty coverage can depend on the use of primers and full adherence to the substrate. Rubberized asphalt is UV sensitive, so extended exposure to sunlight is not recommended. Compatibility between rubberized asphalt and PVC-molded corner boots and end dams should be investigated prior to construction as plasticizers can migrate from the PVC and reduce the plasticity of the rubberized asphalt over time. This causes the potential for a leak down the road. Metal drip edges typically are used at the face of the wall when installing rubberized asphalt, as many manufacturers require that the membrane be held back from the brick face +/- 1/2 inch. Polyvinyl chloride (PVC)
[ABOVE] Unitized flashings are factory-assembled flashing systems that can be manufactured with any of the different flashing membranes that have been discussed.
Today’s PVCs combine old and new technology to create strong, durable and flexible materials, thanks to the addition of non-migratory plasticizers, which will not leach out of or evaporate from the material. Modern PVCs stay flexible and will not break down and become brittle, which would allow cracks and create leaks. PVCs are as good a membrane as any on the market. A crossover from the roofing industry, PVC membranes have proven their durability, workability and economy on roofs all around the world for many years. Thermoplastic Polyolifin (TPO)
TPO is another product that we inherited from the roofing industry. It is a flexible membrane that has a 30-year life span when installed on a roof, and an unlimited life span when placed in the cavity of a building. TPO has an advantage over all other membranes on the market because laps can be sealed using a butyl sealant or primed polyether, or they can be heat-welded. Heat-welding eliminates the need for separate sealants at the heat-welded locations and uses nothing but a hot air gun and a roller to produce excellent, leak-free results. Low-cost equipment for heat-welding can be purchased for under $100 and reduces the sealant requirements for installing flashing. Unprimed polyethers and polyurethanes cannot be used for sealing this membrane, as surface energy of the membrane will not allow a durable, long-term bond. 20 |

EPDM is yet another roofing crossover material that has entered the masonry industry during the last several years. Comparable to the tire tube material we are all familiar with, EPDM is flexible and easy to cut, and installs easily as it has little memory to the roll in hot or cold temperatures. EPDM is a rubber that bonds well with certain polyethers and butyls when used as a lap and general installation sealant. It is not compatible with PVC-molded corner boots or end dams. EPDM must have similar EPDM components for terminations and corners applications, and it is compatible with most air barriers on the market. Unitized Flashing Solutions

Another improvement in the flashing industry is the introduction of unitized flashing solutions. Unitized flashings are factory-assembled flashing systems that can be manufactured with any of the different flashing membranes that have been discussed. The systems include a membrane, pre-designed membrane laps, screws, weep tabs, termination bar, drip edge, and a mortar collection device that has passed the requirements of the ASTM E-514 water test. Unitized flashing solutions also come with manufacturer-supplied, pre-engineered flashing take-offs, and custom-cut panels for window and door heads delivered to the jobsite. Custom cutting gives the contractor a fully assembled masonry opening head flashing for each exterior wall opening right out of the box. Each custom-cut flashing section is installed as a complete unit, reducing the costs of labor time, equipment rental and general conditions. Technical supervision and training also is provided, with video-based instruction, and live streaming, phone and onsite visits available to assist the architect and contractor. Unitized flashing has a higher initial material cost than
Materials • Technolog y • Trends
field-assembled pieces-and-parts, but with the labor cost savings, plus the reduction in material waste, equipment rental and general conditions costs, unitized flashing solutions are proven to save the contractor time and money over the course of the project. Roll flashing with the mortar collection system factory-assembled to the membrane, but with no attached termination bar or drip edge, also is available. Any of the membranes and composites discussed earlier are offered for this system, which allows the design or construction team to choose the correct membrane for the project. All of the flashing membranes mentioned in this article are compatible with all of the high-loft, non-woven, and unilateral mesh products used in mortar-collection devices and mesh-wall fabrics that cover the entire inner wythe of the structure. It is critical that the wall mesh not be placed behind the termination bar. The mesh should extend over the termination bar and lap about one inch over the flashing. A final major improvement in the sealant and flashing market is that contractors can now obtain answers to their technical questions about nearly anything related to masonry wall construction and design. For example, Mortar Net Solutions maintains a specialized staff who can answer masonry-related questions posed by architects, specifiers, and masons. The flashing and sealant industry is constantly evolving, and the rules determining what makes the best building design and the best building techniques also are evolving. It’s important to keep up with the changes this evolutionary process produces, but all the changes are being made with the intention of helping construction industry professionals prevent every leak, every day for the life of each building. wMD

MESA COMMUNITY COLLEGE (MCC) IN MESA, ARIZ., SERVES THE ACADEMIC NEEDS OF NEARLY 26,000 STUDENTS by offering more than 200 degrees and certificates in everything from biotechnology, computer science, and dental hygiene to mortuary science and urban horticulture. However, it was a re-dedication to music and the arts that gave birth to a new Performing Arts Center, acoustically fine-tuned with an inner and outer shell of sound-reflective masonry. It was not only functional, but artfully designed with musical themes. Inside, the theater is embedded in acoustical-enhancing masonry supplied by Oldcastle Architectural’s Echelon brand, where unique Trenwyth Trendstone walls—in the Black Canyon color pattern—support symphony, choir, band, jazz, percussion, and voice. It also blends seamlessly into the design scheme with the outer walls’ Architectural CMUs in Black Integral Color and Standard Gray. The transformation began when the college purchased the Harkins Movie Theatre, a vacant movie house built in 1979, to drive student interest in the

arts and to offer a broad range of musical, dance, and theatrical performances. Designed by Jones Studio of Phoenix, the $10.3-million, multi-purpose facility, opened as the MCC Performing Arts Center in 2014, an enduring public face of the institution’s music and theater programs. In addition to a 462-seat main theatre, the new 44,000-square-foot structure features a full complement of classrooms, practice spaces, faculty offices, shops, and a lobby. Serving as the project’s lead designer, Brian Farling, AIA and a Principal at Jones Studio, modeled the center’s architecture on the creative repurposing of cherished songs and a deep respect of the Sonoran Desert. Comprising the center’s inner and outer shell, the variety of masonry was chosen both for structure and finish. For example, the architectonics of the new performance hall was defined by two separate enclosure shells and a steel frame. The exterior shell is a composition of exposed masonry and raked, unpainted cement stucco over metal stud framing. The second is an interior exposed masonry enclosure that defines the primary acoustic volume of the hall. The sound chamber also was designed by Farling so that its Echelon Trendstone ground-face masonry units would strategically bump from the walls and serve as an excellent sound reflector. Moving north along the side walls, the bumps change from a module of five masonry units wide by five units tall, all the way down to a single 8x8x16 offsetting in and out to create small bumps.

The side walls of the hall also were scalloped TRANSITIONS TO THE in a series of convex curves to ensure sound waves are sprayed evenly throughout the EXTERIOR SHELL.. audience chamber. While the exterior shell features the standard gray 8x8x16 CMU block that transitions to charcoal color with graphics depicting the opening notes of Gershwin’s “Rhapsody in Blue,” the interior acoustic shell utilizes the same charcoal color, but with Trendstone’s smooth, polished ground face. This acoustic masonry shell has many jobs to accomplish: sound distribution, interior structure, a durable finish, and a visually rich interior. The Trendstone’s density provided an excellent surface for the reflection of sound. The north and east exterior walls of the new performance hall also were arranged with a running bond pattern and sloped and folded to both emphasize the vertical marquee sign marking the main entry courtyard. The folded masonry wall slopes away from the sign, lifting it up to emphasize its presence. The slope is two-degrees off the horizon and was achieved by carefully cutting the stem courses of the masonry at the footing. This “marquee” wall was folded by virtue of an offset coursing detail that slips each block a maximum of 5/8” off center from the one below. The line of the fold ascends diagonally across the north elevation and has no offset. As the wall splays out in either direction, the offset goes from zero to 5/8”, creating the fold. This is further supported by the blending of gray- and charcoal-colored 8x8x16 concrete masonry units at this diagonal. Another integral design component is the interior transitions to the exterior shell, which were constructed with Echelon’s matching colored concrete blocks featuring an integrated water repellent, as does the Amerimix mortar used to install it. Arizona is mostly thought of as a dry, sun-drenched geographic area. But according to Farling, “When you have heavy, violent, and sustained downpours on a building that sits in the sun and bakes most of the time, the results can be rapid degradation. Unlike buildings in other climates, the sun and Materials • Technolog y • Trends
rain work together in a dance that can be very hard on the exterior envelope. For that reason, water repellency in both the block and mortar were essential.” Arizona’s powerful rains were prominently referenced in the form of sloped folds that capture and funnel the rainwater into a flowing waterfall found at the northwest corner of the new building. “We passively harvested rain from 17,000 square feet of the roof, which drains into a sort of ‘knuckle’ with a hole in it—so with every rainfall you get a waterfall, emphasizing the infrequent occurrence,” said Farling. The waterfall’s downspout was also designed as the counterpoint to the vertical marquee sign marking the main entry courtyard. Another interesting highlight is the role of music in the building’s design. Each of the patterns within the new masonry, exterior ornamentation, interior lighting, tile, and carpet were developed to reflect the diversity of the college’s character and as visual expressions of the influential music derived from MCC faculty and staff. “We found the variety of musical styles—Gershwin’s ‘Rhapsody in Blue,’ Mozart’s ‘Cosi Fan Tutti,’ ‘YYZ’ by Rush—to reflect the diversity of the college’s character,” explained Farling. Farling and Jones Studio considers the MCC facility to be one of their most challenging and breathtaking accomplishments. Taking two years to complete (2012-2014), the center has already garnered numerous awards. Among them are the 1st Place Award of Excellence from The National Concrete Masonry Association Design Awards, 2015 Excellence in Masonry Award, and many national and regional merits. “It all came together beautifully,” said Farling. “The masonry was key to the acoustics and physical design elements—it’s an enduring legacy for the college.” wMD To learn more about the MCC’s masonry features, visit www.EchelonMasonry.com.

How laser scanning can aid complex renovations

ON THE NATIONAL REGISTER OF HISTORIC PLACES, THE ATTUCKS SCHOOL IN KANSAS CITY, MO., was built in 1905
for a cost of $36,811. By 1950, it enrolled more than 1,000 AfricanAmerican students before becoming a desegregated elementary school in the 1960s. With potential plans to transform the building into a community performing arts center and offices for the Kansas City Jazz District Redevelopment Corporation (JDRC), the Lee’s Summit, Mo.-based Dalmark Group signed up in 2016 to provide analysis of the building’s structural integrity and to determine whether the space was suitable for adaptive reuse.

While the Attucks School’s history was well known, documentation of the building’s original construction or any of its 100 years’ worth of renovation was hard to find—much less transfer—into a reliable building information modeling (BIM) model. Dalmark’s solution was to turn to Overland Park, Kan.-based engineering and survey firm BHC Rhodes. Armed with a Leica P40 and ZEB-REVO laser scanners, BHC Rhodes was able to create a level 200 BIM model of the interior shell and exterior façade of the building. The team used 25 tripod stations for the P40s to scan the outside and walked the ZEB-REVO to map the inside, according to Robby Dudley, North American channel manager for Bingham, England-based GeoSLAM, maker of the ZEB-REVO scanner and a joint venture between Australia’s GeoSLAM Commonwealth Scientific and Industrial Research Organization (CSIRO) and UKbased 3D Laser Mapping. “Those two point clouds are stitched together and you have a complete interior and exterior BIM model to start any renovations, begin materials estimations, and manage building operations in the future with a very clean, accurate picture,” Dudley said.

The process is being used to create BIM models as well as 3D and 2D as-built project schematics, and it is quickly becoming a beneficial tool in the AEC technology arsenal. Combined with hygrothermal imaging or integrated into remote robotics or drones, laser scanners can provide a full data ecosystem to enable efficient project collaboration, precise construction methods, and a shell and systems blueprint for facilities managers and future building renovators.
Laser scanning is beginning to see widespread use in large, complex institutional and adaptive reuse projects—particularly where historical preservation is a concern.
Precision for preservation High accuracy and fast data capture have differentiated laser scanners from conventional measurement and mapping methods, particularly in construction, according to a December report from Transparency Market Research. The report noted the construction sector stands to reduce process costs and project labor hours as proliferation of the technology grows from a global market worth $959 million in 2016 to an estimated $2.5 billion by the end of 2023. “We’re doing 3,600 scans per week in the U.S., Canada, and Mexico and still see a huge market for laser scanners,” said Ken Smerz, CEO and president of Phoenix, Ariz.–based Eco3d, a provider of topographic, structural, mechanical, and architectural condition capture via laser scanner and other imaging technologies. “But there still aren’t a lot of line items in new construction budgets for laser scanning, so we’re seeing it mostly in retrofit and preservation.” w w w.masonr ydesignmaga zine.com

Omaha, Neb.–based Leo A Daly is blending technologies to produce a highly detailed BIM model. The architecture, engineering, planning, design and program management firm merged laser surveying and point cloud model assembly with hygrothermal wall analysis, groundpenetrating radar and CCT camera surveying to compile the BIM model as the basis for the retrofit of the building into GWU’s art academy. The gallery itself also remains as a tenant. According to Leo A Daly associate and architect Andrew Graham, the project involved replacing a large, old utility and infrastructure component with a modern MEP system in a building where 90 percent of the interiors and the complete exterior were listed on the National Historic Register. “To be successful in meeting those needs, we can’t just go out there with measuring tapes and pencils,” Graham said. “The level of error when you are laser scanning is incredibly minute over hundreds of feet and captures existing surfaces conditions to an incredible level of accuracy.” A mechanical attic pocket above the gallery with skylights, catwalks, and historic iron roof trusses became one of the main locations to run distribution for HVAC and fire protection—and Graham said an additional laser scan of that

space was critical to the team’s understanding of how to make the overall design work. “Laser scan allows us to analyze that at a high level of detail by pulling it into a point cloud that puts us leaps and bounds ahead,” Johnson said.
Part of the BIM conversation According to Dudley, laser scanning is simply part of the larger, growing language of BIM that is enabling greater efficiency and collaboration among project stakeholders and providing a mechanical level of detail that is already proving useful to building operations for facilities managers. “There are so many changes that go on within a structure’s life, and the ability to map those changes prior to a sale or purchase, or prior to renovations in a quick, efficient, accurate way is becoming a key plug-in to BIM,” Dudley said. “BIM is fundamentally a communication technology, so everyone—electrical, MEP, HVAC, the architect, and the GC and the wall guy—can all see the changes going on, enabling as-

designed with as-built construction and saving projects thousands of dollars simply in mapping alone.” Particularly for facilities managers looking to improve operational efficiencies, BIM models and 2D schematics generated from full building laser scans are providing holistic, up-to-date construction documentation for greater asset intelligence. “There is an instant interest in cataloging mechanicals to track maintenance and life-span. So what is initially intended as the basis of construction documentation has ended up being used to manage the —Ken Smerz maintenance processes as well,” said Shawmut VP of New England Ron Simoneau. According to Smerz, the use of laser scanning data output by broader AEC project demographics also could help popularize the technology by spreading costs and providing value across the design and construction process. And the ability to convert point cloud data to two-dimensional construction documentation could hasten the process even faster than BIM. “If 2D output is democratized, we anticipate rapid growth,” Smerz said. “It’s the simplest and least expensive use-case to use that 3D scanner to create accurate 2D deliverables.”
“It’s the sim plest and least expensive usecase to use that 3D scanner to create accurate 2D deliverables.”
What’s next for laser scanning tech Incorporating laser scanners into construction drone and robotics units is likely to further expand AEC use cases for the technology. Both Eco3d and GeoSLAM are exploring applications for drone-mounted scanners, providing some mobility to hardware that is mostly tripod mounted. GeoSLAM also has partnered with Mound, Minn.based Black Dog Robotics to develop a law enforcement and all-terrain exploratory robot for remote laser scanning infrastructure after a natural or manufactured disaster. Outfitted with thermal sensors and a camera, the team hopes to advance prototypes to a deployable unit that could explore and map hazardous areas and help emergency responders determine the structural integrity of buildings before putting human lives at risk. According to Smerz, laser scanning shows high retention among first users, with full adoption following one-time use, and the Shawmut team agrees. “In New England we use it to its fullest capabilities,” Simoneau said. “But out of 500 total projects a year, we have not scaled it yet across the entire organization. There is a cost, and if there is not a corresponding ROI to get to that level of detail we might forego it—but we’re getting a lot smarter about what projects get the best bang for the buck.” wMD w w w.masonr ydesignmaga zine.com

Dryvit President and CEO Mike Murphy called Dryvit’s patentpending NewBrick product a significant advancement in the way buildings are constructed. “We are very excited about the opportunities NewBrick presents for architects, installers, and building owners,” said Murphy. “With NewBrick, we are providing contractors an exciting new product that improves daily productivity, reduces occupational injury, provides greater creative flexibility, and results in a better building process. For owners and architects, NewBrick results in a better building envelope at a lower installed cost.

“Although NewBrick can be installed directly over tilt-wall, precast and concrete masonry units, the larger benefits can be realized when NewBrick is installed over an Outsulation® system,” tt Murphy continued. These benefits include the following: “EVERYONE INVOLVED • Full system warranty for 10+ years, depending on system, including the air/water-resistive barrier IN A PROJECT IS • Continuous Insulation (CI), meeting IECC requirements ALWAYS LOOKING TO • Compliance with NFPA 285 fire testing • Compliance with California’s Title 24, Part 6 Energy Code SAVE MONEY WHILE • Can contribute to LEED points

Weight Matters At 1/12 the weight of conventional face brick and 1/4 the weight of thin brick, NewBrick provides significant advantages to the installer, particularly in multi-story construction. Heavy materials require extra handling and equipment. With NewBrick, it is easy to handle on the jobsite and easy to apply without strain. This results in a fasterto-the-wall methodology for installers, which increases daily production. Bill Gatto, the VP of MGM Masonry, Inc. in Schenectady, N.Y., recently installed [ABOVE] 12,000 square feet of NewBrick on a new-build, multi-story, mixed12,000 square feet of NewBrick use project over the Outsulation Plus MD System by Dryvit. “Everyone was installed over the Outsulation Plus MD involved in a project is always looking to save money while constructing System by Dryvit on this new-build, multi-story, a quality building,” said Gatto. “The biggest selling point for Dryvit’s mixed-use project in Schenectady, N.Y. NewBrick was me telling the owner that it would cost less than thin brick because we could eliminate a whole step in the process since we didn’t need to prep the wall to accommodate the heavier thin brick. The second piece was me telling him that we could match the selected thin brick with 44 |

respect to color and texture. He gave me a brick and Dryvit matched it, and he was very happy with that.” Gatto underscored the time savings associated with the lightweight NewBrick when positioning the product on the job site compared to clay brick. “Getting NewBrick to the wall itself is a much easier process than clay brick,” said Gatto. “Clay brick comes on pallets and you always have to be concerned with how much weight is being put on scaffolding. With NewBrick you never have to worry about this. They are lightweight and easy to move around the scaffold. Loading a scaffold with clay brick takes a substantial amount of time, especially on multi-story buildings, and it involves significant lift equipment costs.” “There’s a huge market for thin brick right now with mixed-use buildings and hotels,” said Gatto. “If Dryvit can tap into that market and give you the same look for a lower cost and a higher R-value, I think NewBrick is going to crush the market.” About Dryvit Systems, Inc.

Watershed Block has introduced a new line of block all made using local materials that celebrate the region of their origin, all produced with the latest in sustainable building materials technology. The Lime White Watershed Block offers a zero-cement formula, a glacier-white appearance, and a novel mix design with a dramatically increased sustainability profile. The block uses no Portland cement, instead deriving strength from the high compression lithification of lime, recycled ground granulated blast furnace slag, and natural clays. The Stanford Watershed Block’s color palette is inspired by the rich reddish-brown sandstone beneath the Stanford University campus. The block’s warm hue emerges as red clay from Amador County is mixed with crushed basalt from Mark West Springs, west of Calistoga, and quarry fines from Nun’s Canyon in the Mayacamas Mountains of Sonoma County. Finally, the Sweetwater Watershed Block (pictured) is comprised of mostly rhyolitic fines from Nun’s Canyon with a touch of crushed rhyolite from the BoDean quarry, both in the Mayacamas Mountains of eastern Sonoma County. The sunrise hue of the Sweetwater Block surfaces as the warm, almost peach color of the Nun’s Canyon fines overpowers the gray basalt from Mark West Springs. Materials • Technolog y • Trends

Why Finance Should be a Part of Your Project Management Strategy When it comes to being successful in business, money matters. In construction (and the masonry industry specifically), budget is especially important. In a time when approximately 85 percent of projects go over budget, it is important to understand how finance fits into the overall project management strategy for each job. Stone is an expensive material to incorporate into a project and its installation requires the work of a skilled craftsman. According to the Project Management Institute, there are four phases of a project’s cash cycle: financing, investing, operating, and returning. The structure of a project should be shaped around this cycle. This cycle likely feels familiar. However, that first step in the process often stifles progress for many construction businesses. The financing step involves selecting a project and securing the capital necessary to complete it. Investing occurs when the contractor invests capital in labor and materials to complete the project. The operating phase encompasses the time that the company is working on the project using financing in addition to working capital. In the returning phase, the company pays back interest on financing and provides a return on investment to shareholders if necessary. You may have the skills and the employees to get a project started and to move through the operating phase, but if you lack financial backing it can be tough to complete the investing and returning phases and grow your business. How do you escape this vicious cycle? Here are a few ways to break down the financing portion of your payment cycle and smooth out your project management strategy. Select the right projects Project selection has its roots in finance; without the proper financial support, you will not be able to hire or pay employees, buy materials, or complete the project. The project selection process should be a strategic one that requires continual evaluation of your business and its readiness to take on a proposed project. In addition to financing, the project selection process should include an analysis of your current portfolio of projects to determine whether your company has the right expertise and that your team can work with the proposed project schedule. |

Estimate accurately Estimation is a part of the bidding process and determines the initial budget and timeline for the project. Accurate estimates can save time, money, and stress during the project’s operation stage if something goes awry. During the estimating process, account for potential change orders and situations that could derail the project budget and timeline. You should be prepared to cover the costs of the most expensive and drastic changes. In this instance, it is important to have experience with the project at hand in order to fully understand the types of roadblocks you may encounter. However, many contractors do not have a large sum of working capital available. They invest it in materials and employees for current projects and must wait until they are paid to replenish capital and increase cash flow. That setup can put a strain on businesses in any industry. The solution to these periodic cash flow issues is simple: secure solid financing before every project. This is nothing new—contractors have been using financing from banks, credit card companies, trade credit, and other third parties to pay for projects. Financing increases cash flow and allows contractors to be more agile and flexible throughout a project cycle. Incorporating financing into your project bids and estimates will allow you to mitigate risk and expand your cash flow so you can take on bigger projects. Keep track of your projects A strong project management strategy can help your team work more efficiently, which may allow you to take on additional projects that increase revenue. Make sure to take a step back and get a bird’seye view of each project you are working on. This practice helps ensure that projects do not go over budget and that they stick to the original timeline—the more closely you adhere to the project scope, the easier it will be for you to deliver the best possible final product. I don’t need to remind you of this, but finances are important. Set yourself up for success by putting in the work to create a sound project management strategy with money at the helm. wMD Materials • Technolog y • Trends
