As the construction manager and general contractor, Kiewit provided design-assist services for the Palazzo Verdi Tower. The project scope for this $57 million project involved constructing a 422,000-square-foot, Class A, 15-story office tower. The project is registered with the United States Green Building Council and is designed according to LEED® Gold guidelines.
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.
A Kiewit-led joint venture excavated over 40,000 ft. of an 18- and 25-ft.-dia. tunnel to develop the Exploratory Studies Facility (ESF). The ESF was constructed to determine the suitability of storing high-level nuclear waste. A unique feature of the project was the use of a "mapping gantry" to provide safe access for project geologists and scientists during excavation.
Occupying two square blocks in downtown Omaha, the Holland Performing Arts Center includes a 2,000-seat concert hall; a 400-seat recital hall; a street-level lobby and covered arrival plaza; an upper-level main lobby; and a semi-enclosed outdoor performance and event garden.
In November 2007, Kiewit completed structural improvements to the Verrazano-Narrows Bridge, located at the mouth of Upper New York Bay. The $68 million project included removing aluminum anchorage access plates at the lower-level roadway and sealing the openings with concrete; installing steel maintenance doors; and installing shielding panels at the underside of the deck and on the main cable strands inside the anchorage walls.
The $21 million Maui Marketplace project involved the masonry construction of a 300,000-square-foot retail space on a 20-acre site. Five major retail tenants and a branch bank, added to the contract during construction, occupy the space. The scope of work included placing 2,200 concrete masonry unit blocks a day, totaling more than 200,000. The team's 30 crew members placed the blocks using 600 linear feet of E-Z Scaffold.
Kiewit, performed aircraft apron and runway repairs at this air station for the U.S. Navy. For the runway repairs, the Naval Facilities Engineering Command recognized Kiewit with an award for achieving significant cost savings by recycling existing materials.
