Potts & Callahan Inc.

Potts & Callahan Inc., a Baltimore-based for-profit corporation, provides snow removal, de-icing, salting, and salt pushing services to federal facilities as a full-and-open prime contractor, with no set-aside participation. The company operates exclusively under full competition on non-set-aside delivery orders, holding single-award indefinite delivery contracts with federal agencies managing critical facility operations during winter weather events.

Potts & Callahan's federal footprint is heavily concentrated in facilities maintenance and snow removal services. The company's primary capability is winter weather management for government buildings — snow removal, de-icing of walkways and parking areas, salting operations, and salt pushing — performed under PSC Housekeeping codes (218 of 238 awards fall under Housekeeping–Snow Removal/Salt, PSC J003). Representative work includes a $316,594 delivery order from the Social Security Administration for snow events #6 and #7 at SSA's Baltimore headquarters complex (issued January 26, 2026 under parent IDC 28321321D00060015), a $285,573 delivery order covering three sequential snow events (#8, #9, and #10) at the same facility (issued January 29, 2026), and a $279,009 firm fixed-price delivery order for snow events #1 through #5 (issued January 26, 2024). Work is classified under NAICS 561720 (Other Services to Buildings and Dwellings), accounting for 117 of 238 awards.

Customer concentration is extreme. The Social Security Administration dominates the portfolio with 152 awards carrying $16 million in combined potential value — accounting for 77% of all awards by count and 83% of combined potential value across all customers. The next four customers (Department of Health and Human Services, General Services Administration Public Buildings Service, HHS Centers for Medicare and Medicaid Services, and the Department of the Army) combined represent only 31 awards. The company has served eight distinct federal agencies in recent years, but SSA's Baltimore headquarters complex is the single operational anchor — the facility houses over 10,000 employees and has triggered seasonal snow-event task orders year over year since the IDC's award on August 1, 2021.

Potts & Callahan operates five primary indefinite delivery vehicles. The largest, IDC SS000760067, has generated 64 task orders worth $7.8 million combined potential value. IDC 6009624647 carries 36 task orders; IDC 06000260011 carries 31 task orders with $1.3 million combined potential value; IDC SS001660017 carries 27 task orders with $1.8 million combined potential value; and the SSA snow-removal IDC 28321321D00060015 (awarded August 1, 2021, with a $5.34 million ceiling through July 31, 2026) carries 21 task orders with $1.9 million combined potential value. Individual task orders under these IDCs range from approximately $4,830 to $279,009, sized to respond to specific snow events or seasonal winter weather occurrences.

Activity has been episodic and seasonal. The past five years show 2022 with 8 awards, 2023 with 1 award, 2024 with 2 awards, 2025 with 6 awards, and 2026 (through February) with 4 awards. The company has obligated $18.2 million of its $19.2 million combined potential value (95% obligation rate), indicating consistent execution. The IDC 28321321D00060015 with SSA is set to complete on July 31, 2026 — less than one year from the current date — presenting a significant recompete opportunity if SSA continues procurement of winter weather services at its Baltimore headquarters facility. The company has been registered with the System for Award Management since February 2002 and operates exclusively as a prime contractor with no subcontract footprint.
