Site work and renovation of a water / sewer project in Santa Rosa, California. Completed plans call for the renovation of a water / sewer project; and for site work for a water / sewer project.

The Project is located at the Reclamation Pump Station E Building located at 4301 Llano Road (3822'03.6"N, 12246'08.6"W) and is described as follows: This project will replace an existing wood framed building housing electrical equipment serving the City's effluent pump station at the Laguna Treatment Plant with a prefabricated metal building. The work includes existing building and selective site demolition, construction of a new concrete grade beam building foundation supported on drilled piers, procurement of a prefabricated metal building including engineering calculations and drawings, building fabrication and erection including building accessories, HVAC improvements, electrical improvements, re-support of existing overhead electrical conduits and cabinets currently supported by the existing building, site grading and surfacing replacement, and gate and fencing modifications. A majority of the existing electrical equipment will remain, and the pump station is required to remain operational throughout the duration of the project. Time for Final Completion. The Project must be fully completed within 140 Working Days from the start date set forth in the Notice to Proceed.
