What David Mason & Associates does

David Mason & Associates (DMA) is a privately held, minority-owned (MBE-certified) civil and structural engineering firm headquartered in St. Louis, Missouri. Founded in 1989, the firm delivers professional engineering, surveying, and field services across disciplines spanning civil engineering, structural engineering, utility market services (including power transmission and distribution), survey and 3D laser/LiDAR drone scanning, sewer cleaning and CCTV inspection, field services, and utility-scale solar/BESS engineering. It serves government and municipal clients, utilities, healthcare systems, higher education institutions, aviation facilities, sports venues, arts and culture institutions, and industrial customers, with seven regional offices across the Midwest, Northeast, Southeast, Mid-Atlantic, Great Lakes, and New England.

The firm operates a multi-discipline practice that takes projects from pre-design through construction administration, using a stack of established engineering platforms (Autodesk Civil 3D, MicroStation, GEOPAK, ARCView/GIS, HEC-HMS, BIM/Revit, LiDAR drone scanning) and its own grading-optimization workflow for solar projects. Notable project credits include the Obama Presidential Center ($850M, Chicago), the CityArch River / Gateway Arch grounds renovation, Busch Stadium surveying and civil work, a multi-year Ameren Missouri underground distribution program ($23M total construction value), and long-running engagements with Burns & McDonnell, McCarthy Building Companies, Forest Park Forever, and various municipal clients.

Revenue is generated on a project-quotation basis through professional service fees, secured primarily via direct business development, long-term client relationships, and teaming partnerships with larger A&E firms and contractors. The firm is family-controlled (founder David W. Mason, AIA, as Chairman/CEO, with Taylor Mason as President, Spencer Mason as COO, and Paul Mason in customer relations), maintains an average employee tenure of about 15 years, has completed 14,000+ projects, and holds MBE certification that supports public-sector contracting opportunities.
