P1 Construction LLC

P1 Construction LLC, based in Lenexa, Kansas, operates exclusively as a subcontractor on federal construction and facilities modification projects, with no prime contract or grant awards in its portfolio. The company is a limited liability partnership organized as a for-profit entity and is a subsidiary of P1 Group Inc., a Subchapter S corporation parent.

P1 Construction's recent work centers on electrical, mechanical, and plumbing systems at two customer agencies. The vendor subcontracts to Honeywell Federal Manufacturing & Technologies on Department of Energy National Nuclear Security Administration programs at the National Security Campus in Kansas City, Missouri, where it performs construction, waste furnace modifications, variable frequency drive installation, and project-specific mechanical and electrical work under Department of Energy contract DE-NA0002839. P1 Construction also subcontracts to Mill Creek Firelake JV LLC on Department of Agriculture Agricultural Research Service projects at the National Bio and Agro-Defense Facility in Manhattan, Kansas, where it handles liquid nitrogen system piping and valve installation, electrical work for bio-vent and condenser exhaust upgrades, and boiler-chiller system upgrades. A single award in August 2024 covered wastewater fine-screen installation and electrical demolition for an unnamed federal customer.

Customer concentration is sharp. The Department of Energy National Nuclear Security Administration (NNSA) accounts for ten of seventeen awards (59% of the portfolio), while the Department of Agriculture Agricultural Research Service accounts for five (29%). The remaining three percent of activity is split across one standalone federal customer. NNSA work flows through Honeywell's broader National Security Campus operations and maintenance contract; USDA work runs through the Mill Creek Firelake joint venture. The vendor sits on one identified parent vehicle, an Indefinite Delivery Contract (12805B24D0003) with four task orders.

P1 Construction's capability footprint tracks its NAICS concentration: facilities support services dominate ten awards, plumbing-heating-air-conditioning contracting represents five, and waste management services covers two. Recent activity grew sharply from three awards in 2024 to eleven in 2025, then moderated to three in 2026 through May. The vendor has no identified set-aside designations and competes full-and-open on subcontract opportunities. Combined dollars obligated across all seventeen awards total $4.2 million, reflecting sub-million task-order sizing characteristic of facilities and construction sub-work on NNSA and USDA programs.
