Trusted Civil Engineering Solutions Nationwide
Haines Gipson & Associates (HGA) has built a trusted reputation over five decades by delivering high-integrity civil, structural, and bridge engineering services rooted in the founding principle of doing things right the first time. Starting with two structural engineers and one client in a basement, HGA has grown into a nationally respected multidisciplinary firm serving 200+ clients across 48 states with a team of 30 employees. Our success stems from combining technical depth with practical, economical solutions, supported by a 90% repeat client rate and a team where engineers average 19 years of tenure, ensuring continuity and expertise.Unlike many firms, we handle CAD and Revit modeling in-house, with the same engineer overseeing projects from design to construction drawings, eliminating handoffs and reducing errors. This direct involvement, coupled with nearly 400 combined years of experience among our engineers, allows us to tackle projects of any scale or complexity while maintaining personalized client attention. Our mission prioritizes efficiency, constructibility, and integrity in every project, fostering an environment where employees thrive professionally and contribute expertise for the long term.
