What Marpac Construction does

Marpac Construction is a Seattle-based, founder-owned general contractor founded in 1995 by Doug Mar and Don Mar. The firm provides preconstruction, general contracting, and construction management services to nonprofit organizations, community development agencies, educational institutions, healthcare providers, and affordable-housing developers throughout Western Washington. Its service portfolio is organized into seven categories: affordable housing, education facilities, healthcare facilities, senior care, market-rate housing, renovation and seismic retrofit, and spiritual-facility construction, with a documented track record of over $900 million in negotiated project value across three decades and a current active backlog above $100 million.

The firm differentiates through certified expertise in sustainable construction across LEED, the Built Green program, the Evergreen Sustainable Development Standard (which it helped develop for Washington State), and the Living Building Challenge. Its core offering combines estimating, value engineering, scheduling, constructability review, and mechanical engineering — a full preconstruction-through-turnover stack — supplemented by a community-impact track record of more than $600,000 donated to over 70 nonprofit organizations in the past decade.

Marpac's business model is project-based, negotiated contracting rather than hard bid, with revenue derived from preconstruction services, general contracting, and construction management engagements. Customer acquisition is relationship-driven and referral-led, supported by deep ties to Pacific Northwest funders, housing authorities, and community-based organizations. The firm operates from a single headquarters in Seattle's International District (1225 S. Weller Street, Suite 500) with a leadership bench of four principals (Preconstruction, Estimating, Construction, and General Superintendent) plus the two founder-Principals Emeritus.

Direct peers

• Walsh Construction Co. Seattle-based general contractor with a strong focus on affordable housing, community, and nonprofit projects in the Pacific Northwest. Direct peer given overlapping nonprofit and affordable-housing customer base, regional footprint, and negotiated project delivery model.
• GLY Construction: Bellevue-based general contractor serving commercial, multifamily, education, and healthcare clients across the Puget Sound. Comparable in regional scope, project mix, and relationship-driven delivery, with overlapping nonprofit and public-sector work.
• Lease Crutcher Lewis: Seattle-headquartered general contractor with deep Pacific Northwest presence across multifamily, healthcare, education, and community projects. Comparable in building type, regional focus, and negotiated project delivery.
• BNBuilders: Seattle-based general contractor focused on healthcare, education, life sciences, and community projects across the PNW. Comparable in mid-sized project mix, nonprofit/healthcare clientele, and sustainability emphasis.
• Lydig Construction: Pacific Northwest general contractor with projects across commercial, multifamily, healthcare, and education sectors in Washington and Oregon. Comparable regional footprint and building-type portfolio, though typically larger in scale than Marpac.

Broad incumbents

• Hoffman Construction: Major Pacific Northwest general contractor working on large-scale commercial, healthcare, education, and multifamily projects. Overlaps Marpac's vertical mix but operates at much greater scale and capacity, including work Marpac would not pursue.
• Skanska USA (Pacific Northwest): Global construction firm with significant Pacific Northwest operations across commercial, healthcare, education, and civil projects. Broad incumbent whose PNW building division overlaps Marpac's nonprofit and multifamily work at larger scale.

Others

• Catholic Community Services of Western Washington (Affordable Housing Developer): Nonprofit affordable-housing developer in Western Washington that develops supportive and low-income housing projects — overlapping the customer side of Marpac's portfolio rather than competing as a contractor. Useful as an ecosystem reference for LIHTC/HUD-funded project pipelines.
