WASTEWATER TREATMENT FACILITY EXPANSION
Stanley Consultants was contracted by the City of Surprise, Arizona, to provide design services to expand the city’s 0.8 mgd treatment facility to a 2.4 mgd plant. In an effort to meet city requirements, the existing undersized plant chlorination system was replaced with a low-intensity, vertical lamp ultra-violet disinfection system. All new unit processes installed under this project (#12745) were required to interface with the existing PLC control system.
PROVIDING CONSTRUCTION ADVICE to the CHINESE
Stanley Consultants was retained to provide construction supervision for a massive navigation and hydroelectric project in Hunan Province, China (project #13106). The project was funded by the World Bank and contained the provision that an international consultant work with the project supervisory staff. Minneapolis office member Craig Johnson was selected to fulfill the advisory role. He made 13 three-week trips over a five-year period. Services included establishing systems to monitor construction activities based on Western contract and supervision practices.
RECONSTRUCTING the I-15 CORRIDOR in SALT LAKE CITY
This project, #13143, for the Utah Department of Transportation involved the reconstruction of 1.5 miles of 6-lane divided freeway to a 12-lane freeway, including two high occupancy vehicle lanes. The project included the reconfiguration of the existing conventional diamond interchange to a Single Point Urban Interchange (SPUI). The company performed design for the roadway and the new interchange. This project was the company’s first work for the Utah Department of Transportation and led to opening of the Salt Lake City office in 1996.
ORWELL DAM SPILLWAY
Orwell Dam’s spillway couldn’t safely release enough water during major floods. Stanley Consultants provided engineering services to the U.S. Army Corps of Engineers to help remedy the problem. The solution was an innovative tailwater control structure, which corrected the dam’s safety deficiencies for a fraction of the standard price.
The 765-foot long tailwater control structure spans the Otter Tail River 300 yards downstream of the eastern Minnesota dam. Water usually flows unrestricted through its five large box culverts. However, during flooding the new concrete structure will restrict extreme flows, forcing the water level between the structure and the dam to rise. The resulting water level increase will prevent streambed erosion and make it possible to safely release a sufficient volume of floodwater through the spillway. The project, #13334, won several design awards.
RE-DESIGN of MOSCOW CHEMICAL WEAPONS DESTRUCTION LAB
The project (#13374) was a design-build contract with the U.S. Army Corps of Engineers Middle East District. Stanley Consultants provided design services for remodeling of 1950s laboratory in Moscow. The laboratory is used to monitor the neutralization of Russian chemical and biological weapons which are destroyed through the Cooperative Threat Reduction agreement between Russia and the United States. The 38,000 square-foot space was renovated into a modern facility to house $15 million of lab equipment.
CENTRAL CHILLED WATER PLANT in PENNSYLVANIA
The project (#13661) provided architectural and engineering services for a fast-track design-build central chilled water plant for an industrial client in Pennsylvania. The plant was designed for an ultimate cooling capacity of 14,000 tons with an option for expansion. Phase I included the installation of both steam turbine-driven and electric motor-driven centrifugal chillers for an initial installed cooling capacity of 12,000 tons.
DEVELOPING SUN CITY GRAND
Sun City Grand is a master planned community encompassing 3,700 acres and a projected residential yield of more than 9,500 dwelling-units. The development, project #13866, is an age-restricted community, which focuses on an active adult lifestyle.
Stanley Consultants was the primary consulting engineer at Sun City Grand since its inception in the mid-1990s, providing infrastructure and subdivision master planning and design, drainage and flood control facilities, water systems, sewer collection system, construction phase engineering and observation services for water supply facilities, complete staking services for all construction.
IMPROVING JAMAICA’S NORTH COAST HIGHWAY
The North Coast Highway is Jamaica’s only arterial highway connecting major cities on the east and west coasts. The government of Jamaica retained Stanley Consultants for the planning, design, and construction management services along the entire length of the highway. This project, #13981, replaced the unsafe road with 168 miles of two-lane asphalt highway with asphalt shoulders and a drainage system to prevent flooding. The three-segment, $220 million project took nearly a decade to complete.
The new highway has improved the country’s economy to such an extent that it is called a national treasure. The Jamaican government recently retained Stanley Consultants to provide design services for the South Coast Highway based on the success of the North Coast Highway project.
INNOVATIVE POWER PLANT DESIGN at INDIANA STATE UNIVERSITY
An illuminated clock tower conceals three 85-foot tall boiler flue gas stacks at the $16 million, 25,000 square-foot power plant on the campus of Indiana State University in Terra Haute, Indiana. Stanley Consultants designed the plant (project #14039), which replaced a 50-year-old facility. The new plant provides heating and electrical distribution for two million square feet of academic and residential-life facilities.
ABBOTT POWER PLANT EXPANSION
Stanley Consultants provided design of a $50 million expansion to the Abbott Power Plant at the University of Illinois at Urbana and Champaign (UIUC). The expansion includes two 12.5 MW combustion turbines, each with a supplementary fired steam generator; two 12.5 MW steam turbines; a 7 MW steam turbine; and cooling towers.
This is the first major capacity expansion to the Abbott Power Plant in nearly 30 years. The cogeneration project produces reliable, cost effective steam and electricity from natural gas and fuel oil, combined with the already low-cost steam produced from coal in three existing boilers. The steam is distributed via 8.7 miles of steam tunnels and 9.2 miles of direct-buried steam pipes to serve 252 buildings on the 1,450-acre campus. The project, #14142, won several awards including Project of the Year by the Midwest Cogeneration Association.
RESTORING the EVERGLADES
The reduction of excess nutrients is key to restoring the natural ecosystem of the Everglades. Specialized wetlands, known as Stormwater Treatment Areas (STA), built at key sites along the top of the Everglades harness nature to remove nutrients from water before it enters the ecosystem. The South Florida Water Management District contacted with Stanley Consultants (project #14275) to design three STAs. Two are located along the Taylor Creek and Nubbin Slough tributary to Lake Okeechobee, the third is located on the Loxahatchee National Wildlife Refuge. In addition to quietly and naturally removing excess nutrients, the STAs provide beautiful views and have become a concentration point for Florida wildlife, waterfowl and songbirds. The areas, immediately endorsed by naturalists, have also become popular tourist attractions.
