EXECUTIVE SUMMARY
On October 19, 2021, City Council awarded a contract to JMB Construction for the Storm Drain Pump Station Electrical Upgrades Project. The project consists of upgrades to the electrical and control equipment at four pump stations, and installation of a new wet well and pumps at one of the stations. The improvements and maintenance executed under the subject contract are complete in accordance with project plans and specifications. Staff recommends City Council acceptance of the work.
BACKGROUND
The City of Alameda’s (City) stormwater drainage system consists of an extensive curb/gutter system, 1,655 intersection and sidewalk culverts, 126 miles of buried pipelines, 11 pump stations, several lagoons with tide gates and 278 outfalls. The system is designed to take stormwater runoff from roads, roofs, and impervious surfaces, until it is ultimately discharged to the Bay through outfalls. Ensuring the long-term viability of the City’s storm system is critical for ensuring proper drainage to prevent roads and neighborhoods from flooding during storm events.
In accordance with the 2011 Storm Drain Master Plan and Storm Drain Pump Station Assessment, staff developed a project to replace the existing electrical equipment at four storm drain pump stations: Main Street, Webster Street, Third Street, and Golf Course Stations. Equipment replaced and installed included control panels, service pedestals, SCADA poles, concrete pads, stairs, fences, gates, electrical equipment, and other items. The Third Street station received a new wet well and pumps.
DISCUSSION
On October 19, 2021, City Council awarded a contract in the amount of $2,030,900, including contingencies, to JMB Construction. Although the project schedule was impacted due to supply chain constraints and wet weather during construction, the project was completed in accordance with the plans and specifications and acceptable to the Public Works Department. The final cost, including all extra work orders, is $1,916,957.76.
