William J. Peltier and Associates, Inc. (WJPA) is a structural engineering consulting firm headquartered near Atlanta, Georgia, founded in 2009. The firm provides structural design and consulting services to architects, general contractors, and industry partners, with a focus on solving complex structural engineering problems across a broad range of project types and construction values.
WJPA’s completed project portfolio spans approximately 1,995 engagements, with individual projects ranging from $1 million to $100 million in total construction cost. The firm operates across five primary market sectors: commercial, educational, multi-family residential, government, and healthcare. In addition to building projects, WJPA also provides structural consulting expertise to the demolition industry, a specialized service area that distinguishes the firm from general-practice structural engineers.
The firm holds professional engineering licenses in 20 states, enabling it to serve clients on projects beyond Georgia while maintaining its Atlanta-area operational base. To date, WJPA has worked with 435 distinct clients. Staff collectively bring 55 years of combined tenure at the firm and have logged 1,800 hours of internal training, reflecting an emphasis on sustained professional development and institutional knowledge retention.
WJPA’s project involvement continues through construction phases, including post-permit and occupancy stages, rather than concluding at permit submission. This ongoing engagement model allows the firm to address field conditions, resolve emerging structural issues, and support contractor teams throughout the build process.
Client testimonials on the firm’s website characterize WJPA as responsive, principled, and collaborative, noting the team’s ability to “resolve critical project issues quickly, reasonably, and economically” and to work creatively with general contractors to protect project schedules and budgets. The firm accepts commissions where clients are active stakeholders in project success.
