Design Schematic. The Engineer shall prepare a design schematic for the interim and ultimate design (both as determined from supporting studies and tasks) and traffic control staging for sequence of construction for the added capacity improvements of IH 35 from .5 mile South of IH 35 / US 59 to MM 13). Major added capacity elements include: Mainlanes – 3 lanes in each direction Southbound Frontage Road – Widening, where warranted Xxxxxxxxxx Road Intersection with IH 35 Southbound Frontage Road Xxxxxxxxxx Road Overpass Tres Equis Turnaround and Overpass Widening Carrier Turnaround and Overpass Widening Braided Ramps at Southbound and Northbound Frontage Roads City of Laredo Thoroughfare Plan Overpass ITS and Xxxxxxxxxxxxx Xxxxxxxxxxxxx Xxxxxxxxxxxx
Design Schematic. Upon approval of the recommended alternative, the ENGINEER will perform digital mapping of the Project as shown in Exhibit 2 below. The corridor will have 1400-foot width (700 feet each side of centerline). Aerial mapping will use the previously acquired 5cm GSD imagery and helicopter LiDAR. Aerial photography and LiDAR will suitable for ASPRS Class I 1” = 50’ scale mapping specifications and to generate 1-foot contours. Aerial mapping photogrammetry will hold to 0.167-foot vertical RMSE on hard surfaces in well-defined areas and 0.33-foot vertical RMSE on soft surfaces. Aerial LiDAR will hold a 0.15-foot vertical RMSE on hard surfaces and 0.33-foot on soft surfaces.
