Feasibility Study Foundation Evaluation Regulatory Review Energy Audit Constructability Review
LOCATION: St. John, U.S. Virgin Islands
Langan, working in conjunction with a team consisting of Clean Planet Funding (a renewable energy financing company) and Vanguard Energy partners (solar installer), completed an energy audit and preliminary feasibility study for a resort owner in St. John’s Virgin Islands. The resort and the people of St. John’s are under a state of emergency because of unreliable and costly electric power, costing nearly five times what the US is paying per kilowatt. The feasibility study consisted of an evaluation of multiple renewable energy options for consideration for the resort owner. Options considered included wave action, solar, geothermal, wind, and utilization of existing onsite backup generation. Key considerations were given to renewable energy cost, energy demand, and available space, regulatory acceptance, facility interruption during construction, storm impacts, and further investigation requirements for the selected alternatives. The results indicated that solar energy is the most practical means for energy and cost savings, along with wind energy to make-up for non-solar energy demands. The ultimate goal is to make the resort a “net-zero” renewable energy resort (able to generate as much energy as the resort uses). As a first step to achieving this goal, the Team focused on the most practical and cost-effective renewable energy systems. Based on our observations and discussions with the client, regulators, and local representatives, the Team proposes solar energy as the primary renewable source of energy and wind as a potential secondary source (for night-time demand). It was estimated that the proposed renewable energy alternative could reduce energy costs saving several million dollars per year.

LOCATION: Port Saint Joe, Florida CLIENT: HB White Investments Port Saint Joe is a small marina city located along the Gulf of Mexico in the heart of “Florida’s Great Northwest.” It’s also the future home of the Northwest Florida Renewable Energy Center, a 45 megawatt biomass-to-energy power facility. Langan has been retained to provide land development engineering services for the proposed facility. These engineering services will address items such as site layout, drainage and stormwater management, as well as potable water, grey water, and wastewater layout. The project site, positioned on 45 acres of land that previously served the community as a dry bulk materials transfer facility, has direct access to County Road 382 and the Gulf County Canal, and also includes on-site rail infrastructure. In substantial supply because of its geographic location, the woody biomass will be delivered to the site via truck with the future options of using both the existing onsite railway connection and the Gulf County Canal for feedstock delivery. Langan will secure permits for the facility through the Florida Department of Environmental Protection (FDEP) and the City of Port Saint Joe.

Site/Civil Engineering Geotechnical Engineering Environmental Engineering Natural Resources Permitting Services
LOCATION: Tallahassee, Florida CLIENT: Biomass Gas & Electric
Biomass Gas & Electric is proposing to construct a biomassfueled electrical generating power plant. The proposed project will generate a nominal net 42 megawatts of electricity. Components of the project consist of a biomass fuel delivery/handling system, a biomass gasification system, a biomass dryer, a gas cleanup system, gas combustion turbines, heat recovery steam generators, and cooling towers. Langan was hired by Biomass Gas and Electric to provide site/civil engineering, geotechnical engineering, environmental engineering, natural resources and associated permitting services. The site is approximately 23 acres and contains wetlands, and an existing high voltage transmission line. The site has approximately 25 feet of grade change from one end to the other, and is known to be in a geologically karst sensitive area. Langan has designed the site to accommodate the most efficient use of the land for the power plant while avoiding impacts to wetlands and balancing earthwork. Langan also designed the horizontal and vertical geometry of the proposed rail spur, which will be used to transport the raw material to the site. Extensive coordination with CSX and the City of Tallahassee was required during the design of the rail spur and the relocation of the existing transmission poles. Langan was responsible for obtaining an Environmental Resource Permit from the Florida Department of Environmental Protection, as well as local permitting. An industrial wastewater discharge permit was needed from the local treatment plant, along with the additional permitting that was required from the Federal Aviation Administration due to the height of the gasifier.

This facility, which boarders the Bronx River, serves as the base for the Bronx River Alliance’s 20-person staff. The building stores canoes and kayaks, provides laboratory spaces for environmental studies, and provides a place for the community gathering. Multiple eco-friendly components were incorporated into the design of the 7,000-SF site. A 10,000-gallon tank was buried to collect rainwater that can feed plants, wash boats and flush toilets. Additionally, a geothermal system helps heat and cool the building and solar panels provide 60 percent of the building’s energy. Langan geotechnical engineers performed a subsurface investigation for the site including foundation design and soil & erosion control services. Site/civil engineering services included DEP water and sewer permitting and site design including grading layout. Value engineering services were provided to design a shallow foundation along the river in order to avoid more expensive piles. Langan surveyors completed topographic (including preparation of “on-ground” site surveys), boundary (property lines and easements), and utility surveys (manholes, catch basins, inlets, and underground pipes/utilities).

Standing Column Test Well Installation
Langan environmental engineers incorporated geothermal energy protocols into the design and renovation of the landmark Lion House located on the historic Astor Court at the Bronx Zoo. The wildlife Conservation Society, which achieved its LEED Gold-rated certification, selected Langan to be on the team to provide geothermal evaluation and design services, among other engineering disciplines. Langan initially reviewed published hydrogeologic data and reports for the Lion House project, which showed conditions favorable for an open loop or standing column well (SCW) groundwater source heat exchanger. Langan subsequently coordinated a seismic reflection geophysical survey to investigate the depths, orientation, and degree of interconnection of water–bearing fractures and faults. A conceptual design of the various heat exchangers that could be utilized led to selection of a SCW system to satisfy the 160-ton heating and cooling load. A 1,300 foot standing column test well was installed and pump tested to establish the sustainable yield of the bedrock. Langan’s final design was for five SCW’s each to a depth of 1,300 feet. Well Installation is scheduled to start in April 2005. Langan will shortly perform similar services for the WCS Institute building.

The $20 million modern structure is located on a tight site. The new structure is surrounded by trees at the top of the hill. That location allowed nearly half of the building to be underground but still exposed to natural light, a key to qualifying for LEED certification. Other green features include a geothermal well system which help heat and cool the building. Langan was the geotechnical engineer and site/civil engineer for the design team led by Ennead Architects. Our geotechnical engineering services included a site subsurface investigation, development of foundation requirements and recommendations, and preparation of foundation-related technical specifications. During the foundation construction, Langan was instrumental in developing revised foundation design criteria for unforeseen conditions. This allowed for foundation construction to continue with minimal delay and extra cost claims. A geothermal well system was included into the building MEP system to eliminate the need for an unsightly cooling tower on top of the building. Langan contributed to the geothermal well system by designing and executing a test well drilling and groundwater pumping program. Two wells were drilled to a depth of 1,500 feet into bedrock. The groundwater flow from the bedrock formation was determined by drawdown and steady state pump tests over the course of several days. The flow rates and the drawdown levels were used by others to design the geothermal well system. The Heimbold Visual Arts Center is the first LEED-certified visual arts center in America (Certified for New Construction).

Standing Column Well for Geothermal Cooling Due Diligence Permitting Design Construction Administration Vibration Monitoring
LOCATION: New York, New York CLIENT: The Moinian Group
A standing column well (SCW) was identified as the best option to provide cooling for a 9,000 SF residential unit located at East 67th Street and Park Avenue in New York, New York. The SCW geothermal system was selected because of aesthetic considerations given the historical and architectural significance of the building; no cooling system structures were acceptable outside the building. Langan was retained to conduct a feasibility study to determine if siting a SCW was possible given the spatial constraints of the project. After determining that the SCW was feasible, Langan prepared the fillings for the required permits from the following agencies: New York State Department of Environmental Conservation (NYSDEC), US Environmental Protection Agency (EPA), New York City Department of Environmental Protection (NYCDEP), New York City Department of Transportation (NYCDOT). Langan designed the SCW and developed a specification and bid sheet to secure a contractor. Langan provided part-time construction oversight and coordinated with co-op management. Project challenges included coordinating with co-op management to close the front door of the building during drilling operations. Equipment had to be staged in a relatively tight area and the building needed to be protected from potential damage during construction. All the construction work needed to be conducted between late May and September. The project was completed to the client’s and co-op board’s satisfaction.

Langan conducted a feasibility study and cost analysis for the various heat exchangers that may be used to satisfy the 100ton geothermal cooling load of the planned Butler Houses Community Center. Open loop, standing column well, and closed loop systems, both horizontal OCiand vertical, were evaluated. Each system was analyzed for its benefits, limitations, site considerations, and relative costs. An open loop system looks promising from a water supply PROJECT SITE perspective, as the site is underlain by the most prolific waterbearing rock formation in the Bronx, the Inwood Marble. However, it is expected that the groundwater will contain elevated hardness, which could lead to scaling of the system components exposed to the groundwater, and result in significant future operations and maintenance. The horizontal closed loop system was found to be infeasible due to Cm insufficient available land area and potential conflicts with Yfc existing utilities.
