MoDOT selected TWM to assist with data collection, contract writing and risk management on this large-scale ADA-compliant project that touched 60 locations in 41 communities in Mid-Missouri. Data collection efforts called for swift, efficient topographic field work using a variety of surveying tools (mobile LiDAR, terrestrial scanners, traditional field crews) in addition to qualified inspectors performing ADA compliance field checks. Our engineers produced right-of-way plans as required to construct pedestrian facilities, and generated CAD base maps that showed areas of compliant vs. non-compliant. TWM was able to meet the tight 6-month deadline to collect and process the huge amount of resulting data to keep the project on track.
