08 Earthwork Summary.zip

This file appears to be a compressed archive containing earthwork summary documentation for a federal highway construction project. The archive likely contains detailed technical summaries, cost estimates, quantity breakdowns, and specifications related to earthwork activities for the Mojave National Preserve road improvement project.

The solicitation involves improvements to approximately 56.5 miles of roads within Mojave National Preserve in San Bernardino County, California, with an estimated project cost between $80,000,000 and $120,000,000. Work includes full depth reclamation and resurfacing of Kelso-Cima Road (19.3 miles), South Kelbaker Road (22.3 miles), and Morningstar Mine Road (14.9 miles), with roadway widening to 26 feet, reinforcement of 48 low water crossings, realignment in select areas, safety improvements including rumble strips and paved pullouts, and surface-course aggregate placement. The Federal Highway Administration's Central Federal Lands Highway Division is coordinating with the National Park Service on this full and open competition invitation for bid with HUBZone price preference. Environmental constraints in this natural resource-sensitive area will significantly impact construction scheduling and operational procedures, requiring particular attention to visitor relations, traffic control, and timely project completion.
