To support the launch of the new Midsize Truck Program at the General Motors Wentzville Assembly Plant, Aristeo oversaw the design, engineering, 3D modeling and construction of two building additions.
Aristeo managed the construction of two building additions at the Wentzville Assembly Plant, including a 40,000 square foot Central Materials Area (CMA) building and a 55,000 square foot stamping addition which included the construction of a new press pit and the installation of new stamping equipment.
Both buildings required site work, soil stabilization, building foundations, slab on grade, structural and miscellaneous steel, metal wall panels, roofing, architectural finishes, fire protection and mechanical and electrical services. The new press pit required drilling shaft foundations to bed rock for support along with an extensive earth retention system to prevent the clays found on site from drying or expanding.
The construction of these two buildings required extensive reworking and relocation of existing underground utilities. Both building utilities and process utilities existing in the footprint of the proposed stamping and CMA additions required relocation and/or removal. In conjunction with our engineering partner, our team performed a thorough site investigation and survey, accurately located the utilities and used drilled piers and bridge beams to build over them without compromising their integrity.
Large 96” diameter and 108” underground storm water systems merged together in a utility vault with an invert elevation of approximately 32’ below the existing grade. The team determined that the removal and relocation of these services would be very costly and time consuming and it was determined in the preliminary engineering phase that they should remain.
