Gary Merlino Construction Co., Inc.

Gary Merlino Construction Co Inc., doing business as Stoneway Construction Supply, is a Seattle-based construction firm that performs concrete and heavy civil engineering work as a subcontractor on federal projects, with 75% of recent awards routed through prime relationships rather than direct federal prime awards. The vendor operates as a parent corporate entity with a named joint venture subsidiary, Merlino Goodfellow A JV, and competes in the commercial construction space without disclosed SBA set-aside certifications across its federal footprint.

The vendor's federal activity centers on concrete construction and structural repair work for civil works projects. All nine recent sub-awards (issued Feb 8, 2024) flow through Manson Construction Co as prime contractor, supporting the Lower Miter Lock Center Gate replacement and associated modifications at the Locks and Waterways facility in Seattle, Washington. The scope spans grout, check post, electrical, anchor bar work, miter seal bearing plate installations, anchorage truss repair, and design deduct modifications — tasks described in the source as concrete-intensive. The three prime awards in the portfolio date to 1995, 1998, and 2000 and predate the recent sub-award cluster by two decades, suggesting the vendor's current federal posture is tied to active subcontract work rather than ongoing prime contract vehicles.

Customer concentration is narrow and localized. The Department of the Army Corps of Engineers — specifically the Seattle Engineering District — accounts for nine awards and represents the totality of the recent sub-award pipeline. The broader Army Corps of Engineers entity adds two awards, and the Department of Transportation Federal Highway Administration contributes one award, for 100% coverage across three distinct customer agencies. The vendor's $6.5 million combined obligated dollars across the twelve-award portfolio reflects the sub-heavy posture and the concentration in regional waterways and civil works projects anchored to the Pacific Northwest.

Activity is sparse and episodic. The vendor received one award in 1995, one in 1998, one in 2000, and then nine awards clustered in February 2024, with no awards issued in the 2.5 years since. The recent cluster on the Locks and Waterways gate replacement appears to represent multiple task or modification line items under a single prime contract vehicle rather than a diversified federal footprint. No parent IDIQs, GWACs, BPAs, or agency-wide vehicles are present in the award portfolio.
