Halff Associates

What Halff Associates does

Halff Associates is an employee-owned (ESOP) infrastructure consulting firm headquartered in Richardson, Texas, founded in 1950 by Dr. Albert H. Halff. The firm provides multidisciplinary professional engineering, environmental, and surveying services to government (federal, state, and local) and private-sector clients, organized around four core solution areas — Infrastructure, Mobility, Placemaking, and Water — and spanning roughly 27 service modules including transportation, water/wastewater, environmental, surveying, geospatial, MEP, structural, landscape architecture, and construction services. Halff generates revenue through project-based professional services engagements, typically procured via RFPs, qualification-based selection, and direct contracts with government agencies and developers, billed on a project or hourly basis under multi-year contract structures.

The business is operated as a private, employee-owned corporation with no external parent, private equity, or venture capital ownership. Halff employs more than 1,500 employee-owners across 30+ offices in Texas, Arkansas, Louisiana, Oklahoma, Florida, and (as of June 2025) Georgia. The firm has grown through a combination of organic regional expansion and a sustained acquisition program — including Morrison-Shipley Engineers (2021), Singhofen & Associates (2024), and C&D Utility Consulting (2025) — adding capabilities (MEP, water resources, utility consulting) and geographic reach. Halff is led by President and CEO Jessica Baker Daily (appointed 2024) with Trey Murray as Chairman of the Board; the firm is recognized on the ENR Top 500 Design Firms list (ranked 23rd nationally in the Environmental category) and the Zweig Group Hot Firm List.
