Our services include LiDAR and Aerial Mapping to collect the necessary data. We complement the aerial information with our ground-based field crews to pick up data that is critical for design including underground utilities and overhead crossings. Blew also offers Ground Penetrating Radar (GPR) services when needed. We typically use feature codes that are in a PLS-CADD format or we can use a standard feature code as requested by the utility. Along with this data, we provide topographical and rectified color imagery mapping including contours in 1’, 2’, or 5’ intervals.
Additionally, Blew has the ability to create easements and plats to assist the design. We also use a system that addresses utility crossings and can create a preliminary crossing matrix upon request. Once design is completed, we offer the construction staking services and the ALTA/NSPS Land Title Surveys if needed in the financing stages of the proposed transmission line.
Our strategy is to provide designers and utilities with the most comprehensive assessment of information available that streamlines the CADD mapping process and we can help with the planning stages early on for the best possible route to establish the proposed corridor.
