Jobs Done Well
The Design Services of Kiewit Engineering Co (KECo) are primarily concerned with the analysis and design of temporary structures. Design Services’ focus is on delivering structural falsework plans, excavation support, cofferdams, special concrete forming systems, maritime structures and steel erection devices. Design Services supports varied applications, including temporary bridge structures (pier caps, bridge overhangs, foundations, girder erection), building support (concrete slab support, foundations) and earthwork (trench excavations, shafts, cut-and-cover tunnels) as well as cofferdams and water restraint systems. Design Services supplies the engineering services to support field operations providing both original designs and peer reviews of structural designs and calculations, construction drawings and field inspections. Design Services covers all stages of the construction process, from bid to execution, and its senior engineers provide consultation for concept development on high-risk and unusual operations.
Benicia-Martinez Bridge – Benicia, CA
For this cast-in-place segmented concrete bridge, Design Services provided designs of temporary structures and special equipment including falsework, formwork, support of excavation, a 2,300-ton catamaran barge, trestles, heavy lift support, pile driving templates and platforms, form travelers and tower crane foundations. Peer reviews for the Benecia-Martinez Bridge included all falsework designs, lifting components, trestles, formwork, segmental form travelers, marine operations and heavy lift and lowering systems.
Cardinals Stadium – Phoenix, AZ
Concrete work for the new Arizona Cardinals Stadium featured four 170-ft.-tall supercolumns as part of a hoisting system for the stadium roof as well as stadium seating, slabs on grade and a unique roll-out field slab that retracts along rails. KECo provided design of the auxiliary table form system, peer review, on-site support of falsework and special forming systems, and on-site engineering support.
Holland Performing Arts Center – Omaha, NE
For Omaha’s Performing Arts Center, KECo provided designs and peer reviews of tower crane foundations, support of excavations, formwork, falsework, heavy lift analysis and on-site support of engineering, complex geometrical grade calculations and long truss stability reviews.
Henry Doorly Zoo Orangutan Facility – Omaha, NE
This $8.5 million facility expansion will enable visitors to observe orangutans in both indoor and outdoor habitats from a variety of perspectives. The two-phase project includes an elevator tower and stainless steel climbing net. Design Services provided design and peer reviews of falsework, formwork and support of excavation for the exhibit structure and elevator tower.
