Grunley Construction Co., Inc.

Grunley Construction Co., Inc., a for-profit Subchapter S corporation headquartered in Rockville, Maryland, delivers design-build, design-bid-build, renovation, and new construction services to federal agencies exclusively as a prime contractor across civilian and defense sectors, competing full-and-open without set-aside designations. The firm operates as the parent entity of Grunley Goodfellow Joint Venture and has accumulated $25.98 billion in combined potential value across 431 prime federal awards since 1989, with $4.91 billion obligated to date.

Grunley's capability portfolio centers on large-scale facility construction and modernization spanning commercial and institutional building construction (247 of 431 awards, per NAICS 236220), with core expertise in design-build delivery, SCIF construction, mechanical and electrical systems upgrades, hazardous material abatement, and historic building restoration. Representative recent work includes a $137 million design-build Border Patrol Station in Eagle Pass, Texas (Customs and Border Protection, September 2026, completion August 2029), a $133.5 million design-build secured federal building on the National Mall in Washington, D.C. (Defense Counterintelligence and Security Agency, October 2023, completion June 2029), a $119.1 million design-build modernization of Wings 7 and 6 of the USDA South Building (Department of the Interior, September 2022, completion July 2026), a $117.8 million MQ-25 Aircraft Laydown Facilities at Naval Station Norfolk (Naval Facilities Engineering Command, July 2026, completion April 2029), and a $76.2 million revitalization of the Hirshhorn Museum Sculpture Garden (Smithsonian Institution, September 2023, completion September 2026).

Customer concentration splits heavily between civilian and defense federal agencies. The National Archives and Records Administration leads by award count (117 awards, $172 million combined potential value), followed by the General Services Administration Public Buildings Service (106 awards, scope not separately quantified) and the Department of the Army Corps of Engineers Baltimore District (39 awards, $2.27 billion). By potential value, however, the Department of Homeland Security Customs and Border Protection dominates with 4 awards carrying $10.24 billion combined potential (primarily the two large border patrol station design-build contracts), followed by the Department of the Navy Naval Facilities Engineering Command with 9 awards valued at $9.38 billion. These five customers account for 93% of combined potential value. The divergence signals a portfolio of high-frequency moderate-value NARA task orders anchoring activity volume, offset by lower-frequency, higher-value indefinite-delivery vehicles with NAVFAC, CBP, and the Army Corps of Engineers.

Grunley holds position on six primary indefinite-delivery vehicles: an $8 billion multiple-award NAVFAC Large General Construction contract for the D.C., Maryland, and Virginia region (awarded June 2026, through June 2034); a $10 billion multiple-award Customs and Border Protection Design-Build Construction IDIQ for border facilities nationwide (awarded May 2026, through May 2031); a $1.136 billion single-award NAVFAC Large General Construction contract for the D.C., Maryland, and Virginia region (awarded September 2023, through September 2028); a $499 million multiple-award Army Corps of Engineers Baltimore District design-build and design-bid-build vehicle (awarded September 2023, through September 2028); a $115 million single-award Defense Counterintelligence and Security Agency contract for the Raven Rock Mountain Complex and surrounding National Capital Region (awarded August 2022, through August 2027); and a $12 million single-award National Archives and Records Administration construction management and design-build IDIQ (awarded April 2026, through March 2027). Task-order activity against these vehicles is concentrated: a single NARA IDV (NAMANAS10D0010) carries 57 task orders worth $34.1 million combined potential, followed by two other NARA vehicles (NAMABF15C0009 with 26 orders, $10.4 million; 88310320D00010 with 25 orders, $48.2 million).

Activity trajectory shows volatility. Awards declined from 18 in 2023 to 7 in 2024, then recovered to 9 in 2025 and 16 in 2026, reflecting the lumpy nature of large construction contract award cycles. The recompete cliff over the next twenty-four months comprises 25 awards with combined potential value of $530.6 million, creating material recompete and renewal exposure.

Service Contract Inventory reporting captures Grunley's federal service-contract activity above the $150,000 reporting threshold: SCI-reported invoicing reached $440.7 million across FY2022–FY2025 (FY2022: $148.1 million; FY2023: $68.4 million; FY2024: $105.5 million; FY2025: $118.6 million). The SCI dataset shows roughly 37 FTEs deployed on average across fiscal years, with FY2022 at peak capacity of 104 FTEs and FY2025 at 36.5 FTEs, reflecting project completion and staffing cycles. On federal services contracts captured in SCI, government-paid hourly rates spanned a median of $345.07/hr, with the 10th percentile at $39.96/hr and the 90th percentile at $976.43/hr, signaling a mix of skilled trade labor, supervisory, and specialized technical roles.

Grunley operates a significant subcontracting footprint: across SCI-reportable prime contracts, an average of 38% of contractor hours were performed by subcontractors, with 285 named subcontractors reported. Recent teaming includes Hercules Fence of Maryland (vehicle barriers and temporary fencing), Continental Fire Sprinkler Company (sprinkler systems), American Equipment Systems LLC (bridge cranes), and Federal Painting Inc. (painting) on major projects. This posture reflects a lean prime staffing model emphasizing project management and coordination while delegating specialized trade execution—a structure common to large-scale federal construction delivery where trade-specific subcontractors operate under defined scopes within the prime's overall management and sequencing authority. The vendor rarely appears as a subcontractor to other primes; its 431 awards include zero sub-awards, positioning Grunley as a prime-driven incumbent firmly established within the federal construction marketplace.
