Typical types of services to be provided are multi-beam and single-beam hydrographic surveys for harbor and channel projects, but may also include topographic surveys, aerial photography, and mapping (LIDAR), terrestrial laser-scanning, GPS control, 3D digital mapping, tidal datum determinations, office computations, and other specialized surveys for use in developing construction contract plans and specifications. The selected firm must demonstrate the ability to provide Autodesk Civil 3D formatted drawings and all support files that conform with the Corps of Engineers CADD/GIS Technology Center A/E/C CADD Standards (version 5.0) using the most recent version of the Autodesk Civil 3D at the time of contract award and follow-on task order award. The AE selected will be required to have sufficient staff, flexibility, and capability to be available on an as-needed basis. It is estimated that 80% of the work under this contract will be hydrographic surveying and 20% will be topographic surveying.
