Class A Licensed Civil Contractor · Culver City, California
Civil & Infrastructure
in Culver City, CA
TDQ Construction handles the civil infrastructure work most contractors in Culver City cannot legally self-perform — sewer laterals, utility connections, site grading, drainage, and concrete. Class A General Engineering licensed since 1987.
Class A — What It Means
Civil Work Most Contractors Cannot Legally Do
California's contractor licensing system separates civil construction from general building. Sewer lateral replacement, utility connections, and major site grading legally require a Class A General Engineering Contractor license — a license the majority of residential and commercial building contractors do not hold.
TDQ Construction has held a Class A license since our founding in 1987. Combined with our C-8 Concrete Contractor license, we can perform every phase of civil infrastructure work in Culver City in-house — without splitting your project between multiple licensed specialty firms.
We serve Culver City including Downtown Culver, Fox Hills, Blanco and all surrounding areas.

The Civil Foundation of Every Project
