Grunley Construction Co., Inc.

Grunley Construction Co., Inc., a for-profit Subchapter S corporation headquartered in Rockville, Maryland, delivers commercial and institutional building construction, renovation, and design-build services to federal agencies as a prime contractor across 423 federal awards valued at $17.49 billion in combined potential value, competing predominantly on an unrestricted (non-set-aside) basis.

Grunley operates across a diversified federal customer base spanning civilian and defense agencies, with customer concentration driven by two distinct ordering patterns. The National Archives and Records Administration leads by award count (116 awards, $170.1 million), placing high-volume, lower-dollar facility maintenance and renovation task orders under Grunley's construction management and design-build IDIQs. By potential value, however, the Department of Homeland Security Customs and Border Protection dominates the portfolio: a single $10 billion multiple-award design-build IDIQ awarded May 1, 2026, for border security and CBP facility construction nationwide represents roughly 57% of all combined potential value. The next tier includes the Department of the Army Corps of Engineers Baltimore District (38 awards, $2.25 billion), the General Services Administration Public Buildings Service National Capital Region (22 awards, $2 billion), and the Department of the Navy Naval Facilities Engineering Command (6 awards, $1.17 billion). Together, these five customers account for approximately 90% of combined potential value despite representing only a portion of the 71% award-count concentration figure, signaling a concentration in large single-award and multiple-award IDIQs rather than distributed spot buys.

Grunley's work centers on commercial and institutional building construction (NAICS 236220), with 239 of 423 awards falling into that category and the majority of PSC coding concentrated in repair or alteration of office buildings (87 awards) and construction of administrative facilities (22 awards). Representative named work includes a $129.97 million design-build renovation of a secured federal building on the National Mall (ENDIST Baltimore, October 2023), a $119.54 million design-build modernization of USDA South Building Wings 6 and 7 (USDA Office of Operations, September 2022), a $106.33 million renovation of the Nolan Building at Fort Belvoir (ENDIST Baltimore, September 2023), a $105.6 million upgrade of Federal Emergency Management Agency facilities at Mt. Weather (FEMA, August 2022), a $74.5 million revitalization of the Hirshhorn Museum Sculpture Garden (Smithsonian Institution, September 2023), a $48.35 million renovation of Building 154 at Naval Surface Warfare Center Indian Head (Naval Sea Systems Command under NAVFAC's large-construction IDIQ, September 2024), and multiple NARA facility projects ranging from $594 thousand to $11 million for parking garage repairs, mechanical replacements, roof work, and fire system upgrades.

Grunley holds four significant prime IDV contracts anchoring its federal delivery model. The Naval Facilities Engineering Command Large General Construction - D.C., Maryland, and Virginia - 2023-2028 IDIQ carries a $1.043 billion ceiling with six delivery orders valued at $1.17 billion in combined potential, supporting military facility renovation and modernization across the National Capital Region through 2028. The ENDIST Baltimore (Defense Counterintelligence and Security Agency) contract for construction services at Raven Rock Mountain Complex and surrounding areas provides $115 million in ordering capacity through August 2027 and has generated $91.3 million in delivery orders for site-specific facility work including building storage operations, consolidated maintenance facilities, and perimeter security projects. The $499 million ENDIST Baltimore multiple-award design-build and design-bid-build construction IDIQ for the North Atlantic Division area of responsibility supports facility projects including utility expansions and specialized construction at Fort Meade, Fort Detrick, and related installations. The newly awarded $10 billion CBP multiple-award design-build construction IDIQ (effective through May 2031) targets border patrol stations, checkpoints, sector headquarters, and air facilities nationwide; Grunley received the award on May 1, 2026, and CBP issued an initial $10 thousand design-build task order study on May 11, 2026. Additionally, Grunley holds single-award construction management and design-build IDIQs with the National Archives and Records Administration valued at $12 million (awarded April 2026, effective through March 2027) and an earlier NARA CM/DB IDIQ from which 57 task orders totaling $34.1 million have been placed.

Activity has shown volatility, declining from 18 awards in 2023 to 7 in 2024, then recovering to 9 in 2025 and 8 in 2026 (year-to-date through December). Twenty-seven awards valued at $841.1 million reach ultimate completion within the next twenty-four months, creating significant recompete exposure and opportunity for competitors. SCI-reported invoiced revenue totaled $322 million across FY2022–FY2024 (FY2022: $148.1 million; FY2023: $68.4 million; FY2024: $105.5 million), reflecting large firm invoicing against multi-year facility renovation contracts. Government-paid hourly rates on federal services contracts captured in SCI span a median of $310.74/hr, with senior labor pricing reaching the 90th percentile of $1,206.36/hr and entry-level work around $9.51/hr.

Across SCI-reportable prime contracts, Grunley subcontracts an average of 40% of total contractor hours to a roster of 212 named subcontractors, indicating a delivery model that blends in-house project management and self-performed work with selective subcontracting for specialized trades and labor-intensive disciplines. Named subcontractors on representative projects include American Equipment Systems LLC (bridge cranes), Federal Painting Inc., M J Bradley Co Inc. (resinous flooring), Hurricane Fence Co., I.B. Abel Inc. (electrical), and Wilcom's Welding Inc. (metal fabrications) on the Joint Missile Maintenance Facility at Letterkenny Army Depot; Baker Concrete Construction Inc., Nicomedia Steel LLC, Delaware Elevator Inc., and Specified Electrical Systems LLC on the Fort Meade SCIF renovation; and Hercules Fence of Maryland, Worch Electric Inc., and a multi-vendor structural and mechanical team on the National Mall secured federal building project. Grunley maintains a subsidiary, Grunley Goodfellow Joint Venture, for potential strategic teaming and specific project delivery.

Grunley competes exclusively on an unrestricted (non-set-aside) basis across its entire prime portfolio, positioning the company in direct competition with large established construction firms across federal civilian and defense facility procurements in the National Capital Region and surrounding areas.
