02 3D Surface Models.zip

This file is a compressed archive containing 3D surface models related to a Federal Highway Administration road improvement project in Mojave National Preserve, California. The models support the Invitation for Bid solicitation (6982AF25B000013) for improvements to approximately 56.5 miles of roads, including 19.3 miles of Kelso-Cima Road, 22.3 miles of South Kelbaker Road, and 14.9 miles of Morningstar Mine Road in San Bernardino County.

The 3D surface models serve as technical planning and bidding documentation for this $80-$120 million road rehabilitation project. The models enable bidders to visualize existing conditions and proposed improvements, which include full-depth pavement reclamation, new asphalt placement with consistent 26-foot roadway widths, minor horizontal and vertical realignment, reinforcement of 48 low water crossings, and safety enhancements such as rumble strips, signing, pavement markings, and paved pullouts. This is a full and open competition solicitation with HUBZone price preference set-aside. Bidders should reference these digital models in conjunction with other provided plans and specifications to develop accurate cost estimates and construction methodology for this environmentally sensitive project within the National Park Service-managed preserve.
