Construction Management

Our labor forces are trained to conduct extensive pre-planning to maximize risk mitigation and limit ongoing disruption to transit and pedestrians’ day-to-day activities when performing demolition services. We implement safety measures to continually incorporate California’s seismic construction requirements into our workflow, when removing debris and building materials from the worksite.


Strategic planning and precision are key to executing a successful excavation project to the approved depths for foundation footings, pile caps and slabs. Safety is our main priority in the dewatering, shoring and excavation of all types of soil materials.

Grading and Paving

We bring the skills, workforce and fleet of equipment to execute small to medium sized grading and paving projects. These projects include grading and paving over projects over 50,000 square feet of construction haul roads to minor patch paving for capping of environmentally sensitive areas.

Hazardous Materials Remediation

Our specialized approach to removing hazardous materials can be adapted based on a worksite’s level of contamination. For more than 30 years, we have continually maintained strict compliance with Cal OSHA protocols and disposed of harmful items ethically, by leveraging the services of hazardous waste landfills.

Partnering with waste management experts has provided us with the ability to guarantee that hazardous materials from Marinship managed worksites are kept at a safe distance from housing, agriculture, and the local water supply.

In addition, we maintain an emergency response plan and provide continuous training aligned with OSHA standards to empower our laborers to dispose of potentially dangerous chemicals, substances and pollutants appropriately.

Marinship is committed to helping the State of California achieve its goal of becoming 100% free of fossil fuels to stop climate change. Within the past few years, we have expanded our focus to developing renewable and sustainable energy assets including solar, thermal, hydrogen, renewable landfill gas, EV charging infrastructure and battery storage.
