General Engineering Contractor

A general engineering contractor built for contaminated and regulated sites

HCI Environmental is a licensed general engineering contractor serving industrial, commercial and public sector sites across Southern California. The work is environmental construction: removing impacted soil, closing underground storage tanks, decontaminating structures and preparing regulated properties for their next use. Because HCI also holds hazardous waste transportation and disposal licenses, the contaminated material leaves the site on HCI trucks with HCI paperwork.

One contractor carries the project. HCI project managers coordinate subcontractors, schedules, materials, permits and agency communication through each phase, so you deal with one point of contact instead of a chain of vendors. Public works registration with the California Department of Industrial Relations lets HCI perform prevailing wage work for cities, counties and state agencies.

Scopes range from a single tank pull to multi-phase remediation with excavation shoring, backfill and site restoration. When unknown conditions turn up mid-project, the same crews are trained and equipped to characterize, contain and remove them in a compliant way without stopping the job.

What does an environmental general contractor do?
It manages construction projects where remediation, hazardous materials and regulatory requirements are part of the job. HCI handles the subcontractors, materials, permits and compliance, and performs the physical work: excavation, tank removal, decontamination and demolition.
What license do you hold for this work?
CSLB 788216 with Class A General Engineering, C-21 Demolition and HAZ classifications. HCI also carries EPA ID CAR000329953, USDOT 4438022 and California Hazardous Materials Transportation License 137055, so the waste side of the project runs under the same company.
Can you remove underground storage tanks?
Yes. HCI removes tanks, samples the soil, prepares the closure report and installs new underground or above-ground tanks when needed. Programs have ranged from a single 550 gallon tank to more than 200 tanks across one installation.
Do you handle the contaminated soil, or do we need a separate hauler?
The same company. HCI excavates, profiles, transports and arranges recycling or disposal of petroleum and metal impacted soil under its own licenses. Single projects have moved more than 10,000 tons of impacted soil.
Can you bid public works projects?
Yes. HCI is registered with the Department of Industrial Relations (DIR 1000004254) and is SAM registered. Cities, counties and state agencies hold on-call and master agreements with HCI.
What if we find unexpected contamination during construction?
HCI crews are trained and equipped to respond in a compliant way. They characterize the material, contain it, remove it and document it, and the project continues. Active releases go to the 24/7 line at 800.988.4424.
What types of properties do you work on?
Industrial, commercial and select residential sites: manufacturing plants, former fuel and aerospace facilities, redevelopment parcels, schools and public buildings. Any regulated property where environmental conditions affect construction.
How much does environmental construction cost?
It depends on the site, the material involved, the depth and extent of impact and the disposal path. Send reports, drawings or photos and we will walk the site and return a written estimate. There is no charge for the estimate.
