Four Seasons Environmental Inc.

Four Seasons Environmental Inc., a Monroe, Ohio–based for-profit Subchapter S corporation, is a small business facility operations and maintenance contractor that operates exclusively as a prime contractor on GSA Schedule deliveries and federal indefinite delivery vehicles, with $32.98 billion in combined potential value across 1,695 recent awards spanning fifty-three distinct federal agencies. The company competes across full-and-open and Total Small Business set-aside delivery orders, BPA calls, and task orders, with no federal subcontract activity in the source data.

Four Seasons Environmental's customer concentration reflects deep, narrow vertical penetration. The top tier by award count includes the Department of Agriculture Agricultural Research Service Field Research Implementation and Information Delivery (376 awards, $29.1 million), the Department of the Air Force (372 awards, $13 thousand), and the Army Corps of Engineers Engineering District Louisville (167 awards, $17.9 million), accounting for 62% of recent awards. By potential dollar value, however, the Centers for Disease Control and Prevention Pittsburgh dominates with 13 awards valued at $1.27 billion combined—anchored by a $252.2 million delivery order for comprehensive facility operations and maintenance at CDC Atlanta through November 2030 and a $62.3 million O&M bridge contract. Defense Logistics Agency Land and Maritime ($119.7 million across 46 awards), Naval Sea Systems Command ($57.4 million across 21 awards), and GSA Public Buildings Service National Capital Region ($48.1 million across 17 awards) complete the top five dollar drivers. This split signals a vendor pursuing many small facility-maintenance task orders across civilian and Army operations while anchoring dollars to CDC, DLA, and Navy platform contracts.

Four Seasons Environmental holds three high-value parent vehicles: the OASIS+ Total Small Business IDIQ (December 2024–December 2029, $999,999,999,999.00 ceiling, multiple award); the OASIS+ Unrestricted IDIQ (December 2024–December 2029, $999,999,999,999.00 ceiling, multiple award); a $50 million single-award BPA with Naval Sea Systems Command for facilities maintenance (May 2025–May 2030); and a $8.7 million single-award Total Small Business BPA with GSA Public Buildings Service for FDA Forensic Chemistry Center operations and maintenance in Cincinnati through May 2027. The company places 339 task orders under an Army Corps indefinite delivery vehicle and 236 under an USDA Agricultural Research Service IDIQ, signaling embedded, ongoing customer relationships. The Multiple Award Schedule itself carries 181 task orders valued at $824.8 million, representing the company's most prolific transactional pipeline.

Capability framing across the award history centers on facilities support services (1,045 awards by NAICS), with secondary strength in civil engineering construction, HVAC contracting, commercial building construction, and electrical work. Concrete work spans housekeeping and facilities operations support (223 awards), maintenance of laboratories and clinics (141 awards), operation of government-owned R&D facilities (139 awards), and equipment maintenance across plumbing, HVAC, and electrical domains. Representative delivery orders and BPA calls from the past year include the $252.2 million CDC Atlanta O&M contract (HVAC maintenance, electrical repair, plumbing, security installation, laboratory repairs, preventative maintenance, emergency response), the $51.9 million CDC Atlanta/Fort Collins O&M order (November 2024), a $11.7 million HHS/OASIS+SB delivery order for Environmental Management and Response Facility operations and maintenance in Golden, Colorado, a $564.7 million GSA facilities re-commissioning project for a new San Antonio federal courthouse (building automation reprogramming, cooling tower remediation, chilled water system correction), and recurring FDA Forensic Chemistry Center maintenance and upgrade calls ranging from autoclave repair to safety railing installation to lab lighting to BSL3 corridor repairs.

Service Contract Inventory data shows Four Seasons Environmental delivering $165.2 million in SCI-reportable invoiced revenue across the FY2022–FY2025 window, with a stable workforce trajectory around 278–282 FTEs and annual invoicing near $41–42 million per fiscal year. On federal services contracts captured in SCI, median government-paid rates run around $76.83 per hour, with the 10th percentile at $67.44/hr and the 90th percentile at $660.96/hr, reflecting a labor portfolio spanning entry-level custodial and equipment-operation roles through senior engineering work. Across SCI prime contracts, the vendor engages subcontractors for approximately 0% of total contractor hours, delivering nearly all work with internal staff—a build-to-suit posture rather than a network-dependent one. The vendor maintains an active GSA Schedule with fifty-five labor categories ranging from guard ($36.66/hr) through forklift operators, environmental technicians, instrument mechanics, plumbers, electricians (up to Davis-Bacon rates of $155.14/hr), and electrical engineers ($209.52/hr), with no security-clearance roles offered.

Activity has grown modestly but consistently: three awards in 2022 to thirty-two in 2024, moderating to nineteen in 2025 (partial-year count) and twenty-six in 2026. Eleven awards valued at $14.4 million combined face ultimate completion inside the next twenty-four months, signaling modest recompete exposure. The corporate structure includes a subsidiary, Automate365 LLC, though the source does not indicate differentiated capability or mission alignment.
