The design-builder for this 75,000-square-foot warehouse and office addition includes 65,000 square feet of superflat floor warehouse space, six loading dock positions, office and laboratory space. The warehouse floor was designed for superflat warehouse racking system installations. As a part of the expansion, the existing dock space was converted into two-story office and laboratory spaces. To accomplish the conversion while maintaining warehouse operations, Walsh sequenced and phased construction to build the new loading dock before finishing the path between old and new docks.
