Sloan Lane Sewer ProjectSLOAN LANE SEWER REHABLITATION
After more than 40 years of service, the Sloan Lane sewer in Las Vegas had sustained severe corrosion.  Stanley Consultants provided a preliminary engineering study which evaluated alternatives for the 45-inch to 57-inch deteriorated reinforced concrete pipe.  Slip lining was selected.  It required minimal excavation, little traffic disruption, and no flow diversion.  Slip piping has now become a viable alternative available for Las Vegas to repair and replace pipelines that are located in heavily congested areas.  The project, #14291, won several design awards.

IOWA’S FIRST SINGLE POINT URBAN INTERCHANGE
Iowa’s first Single-Point Urban Interchange (SPUI) at Mills Civic Parkway and I-35 provides much needed access to the rapidly developing areas in West Des Moines and further west. Stanley Consultants provided full service engineering, coordinating with both the City of West Des Moines and the Iowa Department of Transportation on the project, #14879.  The primary features of a SPUI are that all four turning moves are controlled by a single traffic signal located in the center of the bridge. As a result, a major source of traffic conflict is eliminated, increasing overall intersection efficiency.

UAE Master PlanAIR BASE MASTER PLAN IN MIDDLE EAST
This project, #14935, involved the master planning, design, and construction management for upgrading an airbase in the Middle East to serve the United States and host country air forces.  The project required delivery of full design, specifications, design analysis, cost estimates and computations.  Extensive coordination was required with the Host Nation and U.S. militaries to minimize impact to airfield flying operations during construction.

Construction management involved a team of 25 engineers, technicians, surveyors, and inspectors responsible for supervising and coordinating activities of 1,000 contractor staff.  Through careful management and coordination of contractor activities, works were completed 30 days ahead of schedule and the project ready to receive the first of the new base aircraft. 

Saving St. AnnesSAVING HISTORIC ST. ANNE’S
In 1997, a devastating flood engulfed Grand Forks, North Dakota.   To protect the city from a reoccurrence, the U.S. Army Corp of Engineers developed a comprehensive flood plan with 30 miles of levees and floodwalls.  Unfortunately, St. Anne’s, a local historic landmark, stood directly in flood plan’s path.  Because of its location neither a levee nor a floodwall could be built between the river and St. Anne’s.  It looked as though St. Anne’s would be sacrificed to protect the city until Stanley Consultants recommended building a floodwall, disguised as an 8-foot-wide porch, immediately adjacent to St. Anne’s.  The resulting structure (#15000) protects the city from flooding, saved St. Anne’s from demolition, was the most economical option, and looks like an original part of the historic structure.

IOWA CITY WASTEWATER TREATMENT PLANT EXPANSION
Stanley Consultants was hired by the City of Iowa City to address current and future wastewater treatment challenges.   Necessitated by new ammonia regulations, a $26.5 million expansion at the city’s south wastewater treatment plant doubled its capacity from 5 MGD to 10 MGD. The design of the wastewater facilities was a collaborative effort between City staff and Stanley Consultants.  The project, #15047, included flow equalization and pumping modifications; conversion to vortex grit removal to minimize foaming; additional clarifier, RAS pumping, and disinfection capacity; conversion of the carbonaceous activated sludge system to a single sludge nitrifying system; a new anaerobic digester complex with high strength flow equalization; administration building with laboratory; and a vehicle building.

Heat Recovery Steam GeneratorKYRENE EXPANSION PROJECT
The Salt River Project in Phoenix, Arizona, provides electric service to more than 775,000 customers. Rapid growth spawned an urgent need for additional electric. Stanley Consultants was selected to design a 250 MW expansion to the existing plant, located on a 12-acre site. 

Extensive measures were taken to minimize the plant’s impact on neighbors.  By installing a smaller, highly efficient facility and limiting the use of the existing plant, total air emissions have been reduced.  To meet system demands the plant had to be operational within 24 months.  Concurrent engineering and construction was used.  Wherever possible, modularized and pre-fabricated components were used rather than building components on-site.  Using these and other innovative techniques, the plant expansion went on line in 21 months.  This completed project, #15187, won several design awards.

RECONSTRUCTION OF VIETNAM HIGHWAY
The Vietnamese Ministry of Transport and Communications retained Stanley Consultants to provide design review, tender evaluation, and construction management services for the reconstruction of National Highway 9 in Quang Tri Province, Project #15386. 

Highway 9 connects Dong Ha to Laos and is the only east-west route in Vietnam that can serve large commercial trucks.  The reconstructed 83-kilometer highway has enhanced economic expansion and provides the neighboring countries of Laos, Cambodia, and Thailand with improved access to the Vietnamese port of Da Nang.

MASON CITY EDR SYSTEM
New EPA regulations had put Mason City, Iowa’s radium levels over the allowable limits.   This became the catalyst for the city to upgrade its entire system.    The city contracted with Stanley Consultants to provide design and construction management for the $18 million project.  Improvements included a new central 9.5 mgd water treatment plant with an electrodialysis reversal (EDR) technology system, 28,000 feet of new raw and treated water mains, a new booster pump station, and well rehabilitation.  The EDR system, which removes radium from the city’s raw water supply is the third largest in the world and the 2nd largest in the U.S. The project, #15455, won several design awards.

Collier County SPUICOLLIER COUNTY’S FIRST SINGLE POINT URBAN INTERCHANGE
Stanley Consultants’ services were retained by Collier County, Florida to provide design for the upgrade of the Golden Gate Parkway from a four-lane roadway to a six-lane urban divided roadway, Project #15493.  The Parkway is Collier County’s first Single Point Urban Interchange and the county's first grade separated overpass not on a freeway.  The aesthetically pleasing signature structure has been coined “The Gateway to Naples.”   Views from any angle reveal an aesthetically pleasing structure.

PINEWOOD WASTEWATER PLANT
The Pinewood Sanitary District contracted with Stanley Consultants to bring the Pinewood Wastewater Treatment plant into compliance and retrofit the plant.  An extensive and complex permitting process, which ultimately took six years to complete, was initiated. The retrofit was accomplished through modeling to determine how to make the process work within the existing tankage. The plant’s batch operation was converted to a flow-through, four-train system that incorporated biological nitrogen removal. Because of the vast improvements, downstream cities previously opposed to permitting, now recommended it for licensure.  It now operates legally with the necessary permits.  The project, #15669, won several awards.
