Marinship Development Interest

What Marinship Development Interest does

Marinship Development Interest, LLC is a privately held, MBE-certified heavy construction and civil infrastructure firm headquartered in San Francisco with a secondary office in Oakland. Founded in 1993 by Derek Smith, a Stanford-trained civil engineer and third-generation tradesman, the company delivers a vertically integrated set of construction services including concrete (structural and flatwork), excavation, underground utilities, grading and paving, demolition, hazardous materials remediation, sandblasting, and construction management. It also holds California General Engineering (A), General Building (B), C-31, and HAZ licenses, enabling it to bid as both prime contractor and subcontractor on public and private projects. Marinship serves municipal and state agencies (SFPUC, EBMUD, Caltrain, Caltrans, Port of Oakland), private developers (Tishman Speyer), and nonprofit community developers (MEDA, CCDC) primarily across the San Francisco Bay Area.

The company's revenue model is project-based, generated through competitive bidding on public works RFPs and negotiated contracts with private developers; individual contract values span roughly $333K to $3.8M on municipal work, with joint venture development projects carrying total project budgets up to $100M where Marinship participates as development partner rather than full-price contractor. Go-to-market relies on MBE-preferential procurement channels, established prime-contractor relationships (Shimmick, Sundt/Walsh JV, MWH/Webcor JV), and direct RFP response. Since 2020, Marinship has expanded into renewable energy infrastructure (solar, thermal, hydrogen, EV charging) via partnerships with international renewable energy developers, signing its first commercial 15 MW solar project in Silicon Valley in Q2 2022 and holding a term sheet for 350 MW of utility-scale solar in Texas.

Marinship also operates as a real estate developer on affordable housing projects through joint ventures with Guzman Construction Group, including the $42M Casa Adelante and $100M 1515 South Van Ness developments, and is directly developing 78 condominium units at Hunters Point Shipyard. Marketing is relationship-driven through industry associations (NAMC, United Contractors, CAACC, AABE, CEBA) rather than digital channels. The company is family-controlled with no disclosed institutional investors, and its MBE, SMBE, DBE, SLEB, and LBE certifications function as a regulatory moat granting preferential access to government contracting pipelines.
