What Singhofen & Associates does

Halff Associates, Inc. (operating as Halff) is a private, employee-owned (ESOP) infrastructure consulting firm headquartered in Richardson, Texas, founded in 1950. The firm provides full-service engineering, planning, design, and construction-related consulting organized around four core market sectors: Infrastructure, Mobility, Placemaking, and Water. Its service portfolio spans 28+ specialized offerings, including coastal engineering, flood infrastructure design, intelligent transportation systems, water and wastewater treatment, geospatial services, GIS, landscape architecture, MEP engineering, surveying, and federal services.

Halff operates on a project-based professional services revenue model with quote-based, non-publicly-disclosed pricing tied to scope and client type. Its go-to-market is sales-led and relationship-driven: client inquiries are routed through a 'Contact Us' form to relevant service practice leaders rather than via self-service commerce. The client base is segmented across government and municipal agencies, federal government, and private development clients in real estate, commercial construction, and land development. Distribution is regional within the United States, conducted through direct client engagement.

The firm's marketing footprint includes content and news publishing, industry event participation (e.g., AML's Convention), organic social media (LinkedIn, Facebook, YouTube), and employee/client testimonial content. Its value proposition is anchored on 75+ years of continuous operation, comprehensive single-source service breadth, and a branded "purposed for people" employee culture. No public financials, funding rounds, M&A activity, or leadership transition disclosures are available in the input data.
