Site work for a civil project in Cottleville, Missouri. Completed plans call for site work for a water / sewer project.

As of November 10, 2025, this project has not yet been awarded. A timeline for award has not yet been established. The proposed work includes the furnishing of materials, tools, equipment and labor necessary to install 20 ladders in the BNR tanks #1, #2, #3 and #4 at the Wastewater Treatment Plant (WWTP) in O'Fallon, Missouri. Install 16 ladders in anoxic tanks on the northern end of the BNR Tanks, which are separated by FRP baffle walls and concrete divider walls and 4 ladders in the aerobic tanks on the south end of the BNR Tanks, which are separated by concrete divider walls. See Figures 1 - 3 for ladder locations. Conduits mounted along the railing on the precast walkways above aerobic tanks #2 and #4 will need to be reconfigured to avoid obstruction at the ladder access locations. Conduit will need to be added, and wiring will have to be pulled through the new conduit to account for the lengthening of the conduit pipe. Add junction box, pull wire and splice in new conductors to associated tank equipment.
