Collect, compile, and analyze data from the physical work site, surveys, structural concepts, blueprints, schematics, data, verbal or written specifications, technical drawings, rough sketches, diagrams, and other matrices to support drafting and design activities for single, multi-phase, or multi-site project work. Verify accuracy of calculations, design, change orders, interpretation of contract plans and specifications, recognizing moderate to slightly intricate construction or engineering problems and escalating or resolving any differences, errors, or technical problems for appropriate resolution.
