04 3D Breakline File.zip

This is a compressed file containing 3D breakline data in digital format, supporting the federal highway improvement project for Mojave National Preserve roads. The file provides geospatial information necessary for the design and construction planning of the road improvements outlined in the solicitation, including elevation data and terrain breaklines for the approximately 56.5 miles of roads being resurfaced and rehabilitated across Kelso-Cima Road, South Kelbaker Road, and Morningstar Mine Road in San Bernardino County, California.

The 3D breakline file serves as technical reference material for bidders responding to the Invitation for Bid (IFB) numbered 6982AF25B000013, issued by the Federal Highway Administration's Central Federal Lands Highway Division in coordination with the National Park Service. Contractors will utilize this geospatial data to develop accurate construction plans, cost estimates, and scheduling for the full depth reclamation, pavement placement, roadway widening, low water crossing reinforcement, and safety improvements across the project. The estimated project value ranges from $80,000,000 to $120,000,000, and the file is part of the plans and specifications package available to support full and open competition with HUBZone price preference eligibility.
