Sommerville-Wilson Inc.

Sommerville-Wilson Inc., doing business as Split Rock Studios, provides custom exhibit design, fabrication, and interpretive media services to federal land-management and cultural agencies exclusively as a prime contractor, with a particular focus on the Department of the Interior's National Park Service and Fish and Wildlife Service. The company operates from Brooklyn Park, Minnesota, and competes under small-business set-asides on approximately half its federal work.

Split Rock Studios holds two cornerstone indefinite-delivery contracts with Interior Department bureaus: a $45 million single-award IDC with the National Park Service (awarded May 13, 2022, running through May 12, 2027) and a $6 million single-award IDC with the Fish and Wildlife Service Region 1 (awarded February 14, 2022, running through February 13, 2027), both set aside for small business. Under these vehicles, the vendor receives recurring delivery orders for exhibit fabrication, design, and installation across national parks and wildlife refuges nationwide. Recent representative work includes a $2.09 million firm-fixed-price delivery order with the National Park Service for museum interpretive exhibit fabrication at Wind Cave National Park (awarded September 22, 2022, completed October 31, 2024), a $1.04 million Total Small Business delivery order with the Fish and Wildlife Service Region 3 for Crab Orchard Visitor Center exhibits in Mounds View, Minnesota (awarded March 2, 2023, extended through September 1, 2026), a $301 thousand delivery order with the Smithsonian Institution for exhibit design and fabrication in Washington, DC (awarded December 8, 2023, completion July 30, 2026), and a $165 thousand delivery order with the National Park Service for outdoor exhibit accessibility improvements at Sleeping Bear Dunes National Lakeshore (awarded September 20, 2023, completed September 30, 2024). The vendor's NAICS footprint centers on Custom Architectural Woodwork and Millwork Manufacturing (21 awards), followed by Graphic Design Services (13 awards) and Museums (12 awards), with PSC coding reflecting construction of exhibit design, signage, and publication arts.

Customer concentration is pronounced and Interior-centric. The top three customers account for 64% of awards by count and 94% of combined potential value: the National Park Service National Office anchors the portfolio with 16 awards worth $62.5 million in combined potential value, the Fish and Wildlife Service Region 1 holds 14 awards worth $7.8 million, and the Army Corps of Engineers accounts for 18 awards valued at $250 thousand. The divergence between award count and dollar concentration reflects the Corps' higher volume of smaller task orders relative to NPS's fewer but substantially larger delivery orders. Sixteen distinct federal agencies have awarded Split Rock Studios work over the source period.

Activity has been episodic rather than sustained. The vendor received one award in 2019, one in 2021, six in 2022, four in 2023, and one in 2026, reflecting an event-driven task-order pattern typical of IDC holders rather than steady-state contracting. The combined potential value across all 83 prime awards sits at $80.2 million, with $16.5 million obligated to date (21% realization). Only two awards face ultimate completion within the next twenty-four months, carrying combined potential value of $1.3 million — a minimal recompete cliff relative to the total portfolio.

The SCI dataset, which covers federal service contracts above the $150,000 threshold, captures seven prime records spanning FY2022–FY2024 and totaling $1.7 million in invoiced revenue: $316 thousand in FY2022 across 1.4 FTEs, $37 thousand in FY2023 across 0.8 FTEs, and $1.4 million in FY2024 across 4.7 FTEs. This represents a strict subset of the vendor's federal activity — SCI excludes goods, fabrication products, and micro-purchases, which dominate Split Rock's contract value. On SCI-reportable service work, government-paid rates ran a median of $123.40 per hour, with senior labor priced through $147.41 per hour and entry-level work at $46.44 per hour. The vendor performs all labor internally; the average sub-hours share across prime contracts is zero percent, indicating no subcontractor reliance on federal service work.

Split Rock Studios operates entirely as a prime contractor with no subcontract awards in the source data. The vendor's federal footprint is product-and-fabrication-driven rather than service-intensive, focusing on the design, manufacturing, and installation of physical exhibits, interpretive signage, accessibility infrastructure, and museum displays for land-management and cultural institutions across the continental United States and Alaska.
