About the company
W.o. Grubb Steel Erection Incorporated, operating as Wo Grubb Crane Rental, is a family-owned, Portsmouth, Virginia-based crane rental and rigging services company competing as a prime contractor (94% of recent awards) with no set-aside designation on the listed prime awards. The company provides specialized crane rental, steel erection, rigging support, and hauling services to naval and maritime-focused federal agencies, with over $29.6 million in combined potential value across 167 awards since 1997, and operates under Subchapter S corporation structure as a for-profit organization.
Customer concentration is extreme and deliberate: the Department of the Navy Naval Facilities Engineering Command alone accounts for 113 awards and $28 million of the company's combined potential value — representing approximately 68% of the 167 recorded awards and nearly 95% of combined potential value. Naval Sea Systems Command and Naval Information Warfare Systems Command contribute an additional 21 awards, and the Coast Guard and Federal Aviation Administration round out the agency mix with five and one awards respectively. This Navy-centric posture reflects Wo Grubb's core capability in time-sensitive naval vessel maintenance and gun turret movement operations.
The company's primary contracting vehicle is a single-award Blanket Purchase Agreement with Naval Facilities Engineering Command (N4008512A4514) that generated 57 task orders valued at $4.6 million, with a more recent master BPA awarded November 7, 2025 to ENDIST Huntington carrying a ceiling of $749,000 through April 2030. A second major BPA (N4008516A6112) with NAVFAC generated 29 task orders valued at $4.8 million. Representative prime work includes a February 2026 emergency mobile crane rental for USS Norfolk gun turret work ($102,232), an August 2025 rigging services purchase order for Naval Surface Warfare Center Dahlgren ($15,551), a November 2025 Coast Guard purchase order for crane services on Cutter Spencer, and an April 2026 Federal Aviation Administration definitive contract for crane services at Washington-Dulles Air Traffic Control Tower ($59,796).
Activity momentum accelerated sharply: one award in 2021, three in 2023, two in 2024, ten in 2025, and three in early 2026. The top-category concentration by NAICS reflects the equipment-rental posture: Other Commercial and Industrial Machinery and Equipment Rental and Leasing (71 awards), Construction, Mining, and Forestry Machinery and Equipment Rental and Leasing (50 awards), and All Other Specialty Trade Contractors (17 awards). PSC codes align: Lease or Rental of Equipment — Materials Handling Equipment (59 awards) and Miscellaneous Equipment Rental (53 awards) dominate the portfolio.
In its subcontractor role (6% of recent awards), Wo Grubb delivers rigging and crane services to M.c. Dean, Inc. on naval vessel C4ISR installation programs aboard USS Gerald R. Ford, USS Oak Hill, and USS New York, and to VT Milcom Inc. on vessel rigging work aboard USS Porter, USS Wasp, and USS Laboon. The SCI dataset records one named-subcontractor record in FY2025, with a rounded 0.0 FTE figure; these limited records do not establish why SCI reporting is sparse.
