About the company
Robert D. Niehaus, Inc., a small business economic consulting firm based in Santa Barbara, California, delivers housing market research, cost-of-living analysis, and federal data collection services to the Department of Defense and allied agencies as a prime contractor on 196 of its 205 recent federal awards (96% prime posture). The firm competes predominantly under total small business set-asides on its core Defense Human Resources Activity work and holds single-award Indefinite Delivery Contracts with DHRA valued at $8.655 million (Basic Allowance for Housing data collection and analysis, running through October 2026) and $2.561 million (cost-of-living analysis, through August 2030). A March 9, 2026 delivery order from DHRA for non-housing cost data collection across CONUS and OCONUS duty locations to support Defense Cost of Living Allowance rate establishment, valued at $512,236 and due March 8, 2027, exemplifies the firm's current work.
Robert D. Niehaus, Inc.'s customer concentration is heavily weighted toward Defense Human Resources Activity, which anchors 30 awards worth $50.7 million combined potential value—98% of that figure concentrated in the top five agencies. The rankings diverge sharply: the Army Corps of Engineers Engineering District Louisville places the highest award count (61 awards, $19.5 million) but ranks third by dollars, while DHRA dominates potential value despite placing fewer orders. The Navy Installations Command, Marine Corps, and Coast Guard round out the active defense-and-civilian customer set. Beyond DHRA's two primary IDCs, Robert D. Niehaus, Inc. places work on the GSA Multiple Award Schedule (49 task orders, $7.2 million), Army Corps single-award IDCs (W912QR06D0024 with 13 task orders worth $4.6 million), and multiple Air Force Basic Ordering Agreements. Recent representative prime work includes a $3.359 million cost-plus-fixed-fee delivery order from Navy Installations Command under Seaport-NXG (September 2025 through September 2028) for Human Resources Management and Administration support at overseas installations, a $999,800 firm-fixed-price award from Navy for tenant satisfaction surveys across 10 Navy regions covering over 83,000 residents (August 2024), and a $1.731 million annual delivery order from DHRA for BAH data collection and analysis (January 2026, completing October 2026).
Activity has moderated from a peak of seven awards in 2024 to six in 2025 and two in 2026 (year-to-date), with only four awards (combined potential value $3.8 million) reaching ultimate completion inside the next twenty-four months. The firm operates as a subcontractor on housing requirements and market analysis work beneath HDR Environmental, Operations and Construction, Inc. (five sub-awards since February 2024 covering analysis at multiple Air Force bases and Kadena AB Japan), and beneath Aecom-Baker-Cardno Navfac Atlantic Planning JV (Marine Corps housing market analysis). The core capability spans rental housing cost data collection and analysis, fair market rental value assessments for military installations domestically and overseas, tenant satisfaction survey design and execution, cost-of-living allowance rate analysis, and regional economic consulting. Category concentration reflects this specialization: 103 awards fall under NAICS 541611 (Administrative Management and General Management Consulting Services), with another 58 awards split between engineering services and technical consulting. Service Contract Inventory reporting shows minimal SCI-reportable activity—$154,000 in FY2022 across 0.3 FTEs at a $213/hr median rate—indicating that the majority of Robert D. Niehaus, Inc.'s work is small-dollar task orders under IDCs and BOAs rather than large, multiyear service contracts above the SCI threshold. The firm has maintained stable work across twenty-one distinct federal customer agencies since 1987, with deep penetration in DHRA and the Army Corps of Engineers.
