Topographic AS-Built plan for the design of the project (9 kilometers length) and control stations established by GPS
Study from Carolina to Canóvanas and Canóvanas to Rio Grande. AS-Built of the twelve intersections of roads (86.5 acres), cross sections, and shaft design layout. Locations of piles and piers, bridges, walls and their respective elevations along the route. Establishment of GPS control network, which spreads a network of static measurement based on the Global Positioning System (GPS) to over 14 miles to check the alignment of the project and location of several bridges. We reviewed the controls used by contractors and set new controls to ensure the consistency of the project.
