Kiewit was selected by the City of Somerton for the expansion of their Sequential Batch Reactor (SBR) Wastewater Treatment Plant (WWTP). Prior to the design commencing, Kiewit performed cost modeling and constructability reviews to aid in the determination if a Biological Nutrient Removal Process (BNR) design would be more beneficial than the original concept. Kiewit provided anticipated construction costs and schedules for the conversion of the existing SBRs to a BNR. Kiewit performed the same analysis in developing the cost and schedule for the construction of additional SBRs. These side by side comparisons allowed the selection of the best value expansion approach for the WWTP. The BNR approach was selected and increased the current .8 MGD to 1.8 MGD for an addition of .6 MGD in capacity from the original concept.
The vivaNext - H3 Project is part of York Region Rapid Transit Corporation's plan for the next generation of rapid transit. The project includes the construction of rapidways — dedicated centre bus lanes — and 22 state-of-the-art station platforms. The 6.4-kilometre project will transform the Highway 7 corridor into a visually appealing and pedestrian-friendly environment.
In November 2014, Kiewit Mining Group entered a 10-year contract to provide contract mining services for the Walnut Creek Mine. The operation includes an 80-cubic-yard dragline, a 20-cubic-yard mass excavator, an 18-cubic-yard hydraulic backhoe and a fleet of 150-ton end-dump trucks to move more than 20 million cubic yards of material annually. The captive lignite operation can produce more than 2 million tons of lignite per year and incorporates a blending program that provides consistent quality lignite to fuel two 150-megawatt circulating-fluidized-bed power plants.
A Kiewit-led joint venture constructed the Bay Bridge SAS E2/T1 project. The scope of work involved building the foundation of the self-anchored-suspension 530-foot-tall tower, known as the T1 footing, and constructing the eastern-most support structure, or E2, for the Skyway Segment. The three-part E2 structure is 220 feet long by 80 feet wide and the footing structure is 85 feet long, 73 feet wide and 21 feet thick.
Kiewit Offshore Services performed module assembly and integration work for two modular capture vessels (MCVs). After completion, modules were dissembled from the vessels and moved to permanent storage where KOS employees, along with MWCC personnel, will maintain the modules so that they are prepared for deployment at all times
The Kiewit team engineered, procured and constructed the 800 MW natural gas-fired facility with four 200 MW Siemens 5000F(4) simple cycle units and selective catalytic reduction (SCR), oxidation catalysts, exhaust gas-tempering air fan systems and three fuel gas compressors.
The existing Twin Span Bridge over Lake Pontchartrain, La. was heavily damaged by Hurricane Katrina. The powerful storm surge knocked many of the bridge's concrete segments into the lake. As part of a joint venture team, Kiewit crews constructed 1.1-mile-long high-rise portion of the new twin Interstate 10 bridges.
Positioned comfortably in a historic section of South Omaha, the Salvation Army Ray & Joan Kroc Corps Community Center is a $29 million facility which includes a fitness center, a gymnasium and aquatic, education and family services centers. The six-city-block facility employs more than 40 full-time, year-round employees and more than 40 part-time employees.
