Charleston, SC Ruby-Collins constructed the pump station building and architectural features atop the previously completed wet well structure. The project included structural steel, micropiles, pile caps and grade beams, precast concrete wall panels, masonry, ornamental ironwork, and bridge crane installation.
Our crews also installed and commissioned the pump station’s mechanical, plumbing, fire protection, electrical, controls, and fuel systems, along with diesel stormwater pumping equipment and an emergency generator.
The project was completed with associated site improvements, including grading, paving, utilities, stormwater piping and structures, fire protection, and landscaping, delivering a fully integrated stormwater pumping facility.
The project presented several complex installation challenges requiring innovative solutions. Bridge crane installation occurred after roof joists and sheeting were already in place, necessitating a dual-crane operation. The bridge crane girders were lifted and positioned at a 45-degree angle to lower through the roof opening and set onto the pre-installed crane rails.
The 40-foot tall stormwater pumps required an intricate multi-stage installation process. The lower pump assemblies were lifted using a coordinated effort between the newly installed bridge crane and a mobile crane boom positioned through a garage bay window opening. Pumps were positioned over their designated bays using temporary assembly steel, then stacked and lowered section by section while being assembled in place above each pump bay.
