Bayer Construction Company, Inc.

Bayer Construction Company, Inc., a for-profit Subchapter S corporation headquartered in Manhattan, Kansas, provides road maintenance, infrastructure repair, and aggregate materials supply to the U.S. Army as a prime contractor on total small business set-aside and full-and-open delivery orders. The vendor operates as a small business manufacturer of goods (NAICS 238110 — Highway, Street, and Bridge Construction dominates the footprint, followed by sand, gravel, and crushed stone mining categories), competing predominantly under total small business set-aside designations across Army contracts while also receiving task orders on non-set-aside full-and-open vehicles.

Bayer's customer concentration is extreme and regional. The Army Installation Management Command Southwest Region accounts for 257 awards (68% of total) and $191 million in combined potential value — 87% of the vendor's total portfolio. The Army Installation Management Command Southeast Region contributes 50 awards worth $7.3 million; the Army Corps of Engineers Kansas City District adds 32 awards worth $14.2 million. These three Army entities account for 96% of the vendor's award count and 100% of combined potential value. No other federal customer exceeds 13 awards. Bayer's geographic footprint is confined to Kansas and Missouri, with the overwhelming majority of work performed at Fort Riley, Kansas and surrounding Army installations in Junction City, Kansas.

Bayer executes delivery orders against four dominant indefinite delivery vehicles. The largest vehicle — Indefinite Delivery Contract W911RX18D0007 (a $61.5 million single-award IDV for road maintenance and infrastructure support through December 2028, awarded under total small business set-aside in January 2024) — has generated 86 task orders carrying $34 million in combined potential value since inception. A second critical vehicle, W911RX14D0001, has yielded 100 task orders worth $12.3 million. A third vehicle, W911RX24D0001, carries 22 task orders valued at $7.2 million. A fourth, W911RX09D0009, carries 21 task orders worth $4.4 million. These four vehicles alone account for the vast majority of Bayer's recent delivery order activity. A single-award aggregate stone and sand supply contract (ceiling $5.9 million, awarded January 2022, completion December 2026) rounds out the vehicle portfolio.

Representative capability work includes: road repairs to Ray Road at Fort Riley ($701,405); road maintenance services at Fort Riley ($773,124); mill and overlay work on Sheridan Avenue ($310,240); pothole repair at Fort Riley ($100,319 and $104,742); road repairs to Armistead Avenue with mill and overlay ($991,735); road repairs to Brown-Graves-Bullard-Siebert roads ($634,588); road repairs to Trainfire with mill and overlay ($2.08 million); and a large regional bridge and road repair project — Vinton School Tank Trail Bridge with K&L work ($2.38 million). Most work is firm fixed-price with performance periods ranging from three to twelve months.

Activity has declined year over year: 24 awards in 2022, 21 in 2023, 16 in 2024, 14 in 2025, and 6 in 2026 (through May). The recompete cliff exposes $5.1 million in combined potential value across seven awards reaching ultimate completion within the next twenty-four months. Obligated dollars represent 34% of combined potential value ($73.7 million of $219.1 million), indicating a heavily backloaded portfolio with substantial unobligated task order authority on the road maintenance IDVs.

The corporate structure includes a named subsidiary, Larson Construction, Inc., a for-profit Subchapter S corporation. Bayer operates with minimal subcontract exposure — the source identifies only one sub-award to Bayer under Fort Riley Utility Services Inc. (October 2024, asphalt paving modification). Bayer itself serves as a pure prime contractor across the federal footprint, with no role as a sub-contractor to other primes.
