A leading design-build specialty contractor, Schnabel customizes innovative solutions to help clients achieve their boldest ambitions. Working with Granite Construction, we designed and built a complex system of excavation support to divert railway impediments and help alleviate traffic congestion in the City of Reno.
Owner: City of Reno
General Contractor: Granite Construction
Design/Build Specialty Contractor: Schnabel Geostructural Design & Construction
Traffic in downtown Reno had become increasingly congested due to numerous railroad crossings. To reduce this congestion, the City of Reno contracted with Granite Construction to put a portion of the railroad in a depressed trench, so rail traffic could pass through the city unimpeded. The depressed portion was around 2.2 miles long, 54 feet wide and up to 35 feet deep.
Granite selected Schnabel to design and build the complex system of excavation support and underpinning to complete this project. Schnabel selected soil nailing to provide excavation support where there were no structures and a combination of hand-dug piers and micropiles to support the adjacent structures.
This particular project was awarded the 2006 Outstanding project award by the Deep Foundations Institute (DFI), further enhancing Schnabel’s reputation for delivering innovative solutions for unique construction challenges.
