Construction Support Services



Nelson Engineering provides multi-disciplinary pre-construction, construction, post-construction and Title II inspection services. We ensure design-bid-build and design-build projects are completed on-time and on-budget. We serve as owner advocates to ensure newly constructed systems meet design intent and mission requirements. Our construction support solutions focus on ensuring facility assets achieve cost-efficient operation.
