DEC provided geotechnical foundations design for both Hoist and Winch Foundation and the 200 ton Gantry Crane Foundation for the Contractor, Las Vegas Tunnel Constructors, in 2008 and 2009. Design requirements included “quick turn-around” analyses and design for a large foundation for a Hoist and four (4) Winches.
DEC evaluated the sub grade soils and work closely with a structural engineer to design: a 60 x 60 x 5 ft mat foundation to support the Hoist and Winches, and two (2) 20 x 20 x 3 ft strut foundations to support the Head Frame. DEC prepared plans and specifications for the projects.
Because this unique design project was completed on time and within budget, DEC was asked to expand our services to design a challenging Gantry Crane foundation. Again, the project required on a very short turn-around in the late summer of 2009.
