Glen Mar-Hensel Phelps

Glen Mar-Hensel Phelps, a joint venture women-owned small business based in Clackamas, Oregon, delivers design-build and design-bid-build construction services for Navy and Marine Corps infrastructure projects across the Pacific region as a prime contractor (100% of recent awards), competing under total small business and partial small business set-asides. The company is a child entity of Glen / Mar Construction, Inc., a certified women-owned small business and self-certified HUBZone joint venture structured as a Subchapter S corporation.

Glen Mar-Hensel Phelps' capability portfolio centers on critical infrastructure repair, replacement, and upgrades for military installations in Hawaii and the Pacific Northwest. Recent representative work includes a $39 million firm fixed-price delivery order awarded February 2025 by Navy Installations Command to replace a 24-inch transmission waterline along Lehua Avenue in Pearl Harbor, Hawaii, with completion scheduled June 2026; a $17.5 million delivery order awarded March 2023 to replace a 24-inch water transmission line at Joint Base Pearl Harbor-Hickam with specialized gasket and mitigation work; and a $10.8 million delivery order awarded January 2026 by the Marine Corps to repair the Eastside Installation Security Fence at Camp Smith, Hawaii, completing January 2027. Work also includes electrical system upgrades such as generator and main switchboard replacement at Camp H.M. Smith.

The vendor's customer concentration is highly concentrated within the Department of the Navy ecosystem. The Department of the Navy and its sub-organizations account for 100% of recent awards and combined potential value. The Department of the Navy Naval Facilities Engineering Command (NAVFAC) anchors the portfolio with a $1 billion multiple award indefinite delivery contract for design-build and design-bid-build construction services across Washington, Oregon, and Idaho through September 2031, partially set aside for small businesses. Navy Installations Command ranks second with three delivery orders worth $56.5 million combined potential value, and the United States Marine Corps holds two awards totaling $17.2 million. Glen Mar-Hensel Phelps also holds a $499 million Design-Build/Design-Bid-Build Small Business Multiple Award Construction Contract (MACC) through NAVFAC for various locations throughout Hawaii, running through November 2026 and exclusively reserved for small businesses.

Combined potential value across all eight awards totals $1.57 billion, with $73.7 million (5% of ceiling) obligated to date. Five delivery orders under the Hawaii MACC have generated $73.7 million in combined potential value; one task order under the NAVFAC MACC Construction vehicle carries a $5,000 minimum guarantee. Activity shows one award in 2021, one in 2022, three in 2023, one in 2025, and one in 2026, reflecting an uneven cadence driven by large indefinite delivery contract awards. One award valued at $10.8 million faces completion within the next twenty-four months, presenting a near-term recompete opportunity. The vendor's work is concentrated in commercial and institutional building construction (NAICS code–based, covering all eight awards) and construction of miscellaneous buildings (PSC category).
