About Larson Design Group, Inc.
Larson Design Group, Inc. operates as an architect-engineer services provider delivering federal infrastructure design and engineering support primarily as a prime contractor on civilian indefinite-delivery contracts and as a subcontractor on state-administered federal grants. The company is a for-profit Subchapter S corporation headquartered in Williamsport, Pennsylvania, competing in full-and-open procurements without set-aside designations across its prime federal footprint.
Larson Design Group's core capability centers on architectural and civil-engineering services for federal infrastructure modernization. The company holds two multiple-award indefinite-delivery contracts with the Federal Aviation Administration's Southwestern Region, both valued at $271.953 million with ceilings running through 2036, structured under the Bipartisan Infrastructure Law and Facilities & Equipment funded Architect and Engineer Services Recompete program covering Tier 1 and Tier 2 funding. Recent prime work includes a $122,487 delivery order from the FAA Southwestern Region for architect-engineer services on waterproofing and concrete repairs at the Savannah Air Traffic Control Tower, with completion targeted for May 2030. The company's subcontract footprint spans civil engineering design work as a sub to Korte Construction Company on a Department of Defense building repair project and structural, architectural, and civil design services on multiple bridge-replacement grants administered by the Pennsylvania Department of Transportation as prime grantee, including projects on Stoney Point Road Bridge in Adams County, Furnace Road in York County, and North Lincoln Avenue Bridge in Lebanon County.
Larson Design Group's customer base is heavily concentrated in Department of Transportation accounts, which account for 81% of awards by count. The Federal Aviation Administration's Southwestern Region dominates potential value, carrying three awards worth $544 million in combined ceiling value, while the Federal Highway Administration accounts for seven awards with $104 thousand combined potential value routed through the Pennsylvania DOT grant pipeline. The General Services Administration Federal Acquisition Service, Department of Veterans Affairs, and Department of Agriculture round out the active customer set. Activity has remained modest and episodic — four awards in 2024 and four in 2025 — with one award issued in 2026. Combined obligated dollars across all sixteen awards total $2.1 million against $552.2 million in combined potential value, indicating limited drawdown on the large FAA IDIQ ceilings to date. The parent corporate structure includes a joint-venture subsidiary, Ldg-Jg&A-Tsg JV.
