SOW 1.0 Background on the Government’s Requirement BLM Northern California District requires pavement rehabilitation of approximately

14.04 miles of the Sacramento Rail Trail system near Redding, California. The project includes the Shasta Dam Trail (8.23 mi), Keswick Dam Trail (2.85 mi), and Middle Creek Trail (2.96 mi) segments. See Figure 1. Sacramento Rail Trail Project Location.

The trail provides critical public access for pedestrian and bicycle use and supports periodic BLM administrative vehicle access. The existing asphalt pavement exhibits transverse and longitudinal cracking, localized structural failures, and shoulder degradation (see EX-4 Photos). Without repair, these deficiencies will continue to propagate, resulting in reduced safety, increased maintenance costs, and diminished user experience.

This project consists of localized “remove and replace” patching, surface preparation, crack sealing, asphalt overlay, and shoulder backing. Additional work includes conformed grinding at intersections, and paving interface work around existing locking bollards.

SOW 2.0 General Scope of Work The Contractor shall furnish all labor, equipment, materials, supervision, and incidentals necessary to complete pavement rehabilitation of the Sacramento River Rail Trail system.

See EX-3 Maps and EX-4 Photos.

SOW Page 3

• Reclaimed material not suitable for structural reuse may be approved by the COR for use as shoulder backing when it is reasonably well graded, free of deleterious material, and capable of being placed and compacted to provide a smooth, stable shoulder. Class II aggregate base remains the required bid basis for Task 7 unless reclaimed material is specifically approved by the COR.

• Material unsuitable for either structural reuse or approved shoulder backing shall not be incorporated into the work and shall be disposed of in accordance with applicable requirements.

• In-place pulverization, stabilization, or Full Depth Reclamation (FDR) methods are not required under this contract

• Proof roll subgrade to identify soft or unstable areas; undercut and replace as directed by the COR

• Place aggregate base as required to achieve a stable section (typically 4–6 inches), in lifts as necessary to achieve compaction

• Place hot mix asphalt (HMA) patch to match the thickness of the existing pavement section, but not less than 2 inches compacted thickness

• Compact HMA to ≥92% of maximum density in accordance with FP Section 154

• Finished surface shall be flush with adjacent pavement (≤0.25 inch deviation)

• Completed repair areas shall be incorporated into the final asphalt overlay profile

Task 3 – Surface Preparation

• Sweep and clean pavement surface to remove dust, debris, and loose material

• Remove loose vegetation, debris, dirt, and other material from the pavement surface and pavement edge as necessary for surface preparation. General clearing, grubbing, tree trimming, and shoulder vegetation clearing are not required under this contract; BLM will complete planned shoulder vegetation clearing prior to

NTP.

• Apply crack seal to cracks ≥ 1/4 inch in width outside Remove and Replace Patching areas. Use a commercially manufactured pavement crack-sealing product compatible with the existing asphalt pavement, tack coat, and HMA overlay. Hot-applied or cold-applied products are acceptable when intended for asphalt pavement crack sealing and approved by the COR.

• Submit crack-seal product data for COR review prior to use. Install in accordance with manufacturer recommendations and allow the material to cure or otherwise become ready to receive tack coat and HMA before overlay operations.
