Con-Quest Contractors has among the most loyal and experienced hands in the industry. Our seasoned superintendents and foremen have more than a century of collective experience in heavy engineering projects and have a broad knowledge of construction practices ranging from underground infrastructure work to rail transit systems.

Con-Quest Contractors’ personnel have managed and worked on many notable projects throughout the Greater Bay Area, such as the Vasona Light Rail & Tasman to 880 Extensions for the Valley Transportation Authority (VTA).  Our crews have constructed much of the MUNI Embarcadero Light Rail Line and Market Street Car Line in Downtown San Francisco.  Our crews also constructed the south line extension for Sacramento RT, as well as the CTX “baby bullet” project for the Peninsula Corridor Joint Power Board (PCJPB –aka Cal-Train).  In addition to these major transit projects, our team has been involved in major infrastructure projects such as the Recycled Water Program for the City of San Jose, constructing major water projects for the City & County of San Francisco, as well as flood control projects for the Santa Clara Valley Water District.

Con-Quest Contractors, Inc. was established in 2008, at a time when the economy took one of the biggest hits in history.  Yet despite the economy and funding cuts, Con-Quest Contractors has been able to consistently grow our revenue each year.  We attribute our success to our belief that a project can only be considered a success if the Owner, the Stakeholders, as well as C-QC, are pleased with the results.


Regardless of the contract structure, Con-Quest Contractors approaches each project as a partner with the owner or prime.  C-QC prides itself in putting the project first, watching out for the concerns of all the stakeholders, not just our own.
