SOW 1.0 Background on the Government’s Requirement BLM Redding Field Office requires pavement rehabilitation at Reading Island Campground. Reading Island Campground is a high-volume use area that offers numerous recreation opportunities for hunting, camping, hiking, boating, picnicking, and wildlife viewing.

The parking lot and site road have extensive cracking and full-depth pavement failure with unsafe shoulder drop-off. They were last paved over 30 years ago. The site road and parking lot exhibit fatigue cracking, potholes, and structural degradation. This project will perform targeted full-depth repairs, and a two-lift asphalt overlay to extend service life and improve safety.

SOW 2.0 General Scope of Work The Contractor shall furnish all labor, equipment, materials, supervision, and incidentals necessary to complete asphalt pavement repair and overlay over approximately 94,000sf of site road and parking lot.

Place of Performance:

See Technical Exhibit 4 – Maps.

Reading Island Campground Cottonwood, California Approx. Coordinates: 40.389944°, -122.197759°

Period of Performance:

45 calendar days from Notice to Proceed.

SOW Page 2

SOW 3.0 Overall Objectives The objective of this work is to restore pavement integrity, extend functional life, and improve safety. The work will be performed in four areas of the campground: (1) entrance site road, (2) parking lot, (3) full depth repair within parking lot, (4) lower site road. See Figure 3. Project Site Map.

• Site Roads o Upper half from the county bridge to the parking lot o Lower half from the parking lot to group camp site o 20ft wide x 2,700ft long o Approximately 54,000 sf o See EX-3 Photos

• Parking Lot (3) o Approximately 40,000 sf o Site of 4000sf of Full Depth Repair – see Task 2 o See EX-3 Photos

SOW 4.0 Specific Tasks Task 1 – Mobilization

• Coordinate with COR to arrange pre work site meeting

• Confirm Delivery/Performance Schedule

• Submit mix design and material order sheets

• Upon receiving NTP, mobilize as per approved Delivery/Performance Schedule

• Survey/Layout: No formal construction surveying is anticipated. The work generally follows the existing paved footprint and existing grades except for localized corrections necessary to provide positive drainage and smooth transitions. The Contractor remains responsible for construction layout and measurements necessary to execute the work in accordance with the contract requirements.

Task 2 – Full-Depth Repairs (~4,000 SF)

• Full-depth repair areas shown on Figure and will be field marked by COR before

NTP.

• Quantity is estimated, actual may vary within contract terms

• Contractor shall sawcut neat boundaries

• Contractor shall remove failed asphalt and unsuitable base to competent subgrade.

SOW Page 3

• Existing asphalt within designated full-depth repair areas may be ground or pulverized as part of the Contractor’s means and methods. Suitable reclaimed asphalt/grindings may be reused as fill/base within the repair areas when properly placed, graded, and compacted to provide a firm and stable section prior to localized leveling and placement of the final HMA overlay. Unsuitable material shall not be incorporated into the pavement section.

• Proof roll subgrade

• Place 6 inches aggregate base

• Place 2 inches HMA

• Compact to required density

• Full-depth repair areas shall be repaired to section depth as specified, then incorporated into the final two-lift overlay work.

o If unsuitable subgrade material is encountered below the specified excavation depth, the Contractor shall notify the COR. The COR will determine the limits of additional excavation (undercut) required.

o Undercut is anticipated to be a minor quantity adjustment and shall be handled within the contract.

o Undercut shall not exceed 10 inches below the specified section without written approval from the COR.

• Excess rock, pavement grindings, and other suitable inert construction material not incorporated into the work may be stockpiled in the BLM-designated clearing immediately north of the parking lot. The COR will identify the stockpile location in the field. Unsuitable material shall be disposed of by the Contractor in accordance with applicable requirements.

Task 3 – Surface Preparation

• Sweep and clean pavement

• Remove vegetation and debris

• Clearing/Tree Limbs: No general clearing and grubbing is anticipated or required as a separate work item. If minor tree-limb trimming is necessary for safe equipment access, the Contractor shall coordinate trimming limits with the COR before performing the work. Approved vegetative debris shall be lopped and scattered within the swale east of the parking lot. Removal of trees is not authorized unless specifically approved by the Government.

• Cracks 1/4 inch or greater in width outside designated full-depth repair areas shall be cleaned of loose material, vegetation, dirt, and debris and sealed prior to HMA placement using a hot-applied, rubberized asphalt crack sealant suitable for flexible asphalt pavement.

SOW Page 4

• Crack sealant shall be installed in accordance with the manufacturer's recommendations. Cold-applied crack fillers or sealants shall not be used unless specifically approved by the COR.

• Crack sealant shall be allowed sufficient time to cool, set, and cure as applicable in accordance with the manufacturer's recommendations prior to application of tack coat and placement of HMA. Excess sealant or other material that would interfere with tack coat application or bonding of the HMA overlay shall be removed or corrected prior to paving.

• A leveling course may be applied as needed to correct surface irregularities prior to placement of the asphalt overlay. Leveling course shall be included in the unit price for asphalt overlay and shall not be paid for separately.

• Apply leveling course as necessary to provide a smooth, uniform surface suitable for placement of the specified HMA overlay.

Task 4 – Tack Coat

• Apply tack coat between all lifts

• Follow FP-14 application rates

Task 5 – Asphalt Overlay

• Place two lifts of HMA (0.10 ft each)

• For bidding and construction, the required overlay is two 0.10-foot compacted HMA lifts, for a total compacted overlay thickness of 0.20 foot.

Placement as a single 0.20-foot lift is not an approved substitution.

• Roadway Width: Match the existing paved roadway width. The project does not require widening roadway sections to a uniform 18-foot width. The new overlay shall generally follow the existing pavement limits unless otherwise directed by the COR.

• Use 1/2-inch NMAS PG64-10 mix

• Compact HMA to a minimum of 92 percent of Maximum Theoretical

Density (Rice Density).

Task 6 – Shoulder Backing

• Shoulder backing shall consist of 3 inches of compacted Class II aggregate base at the finished asphalt edge, placed level with the finished asphalt grade and tapered to match existing grade over an approximately 2-foot horizontal width along each side of the site road.

Task 7 – Quality Control

• Submit mix design

• Provide haul tickets

SOW Page 5

• Density testing shall verify a minimum of 92 percent of Maximum Theoretical Density (Rice Density). The Government anticipates use of a calibrated nuclear density gauge operated by qualified personnel for routine density testing. Alternate non-destructive methods, including PQI, may be proposed for Government review and approval. The Government reserves the right to require verification by asphalt core sampling where necessary to resolve discrepancies or verify compliance.

• Correct deficiencies

Task 8 – Site Restoration and Demobilization

• Cleanup all construction debris

• Arrange final walkthrough of site with COR

SOW 5.0 Delivery / Performance Schedule Contractor shall complete all work within 45 calendar days from issuance of Notice to Proceed (NTP).

All submittals must be reviewed and accepted by the Contracting Officer’s Representative (COR) prior to issuance of NTP.

A pre-work (preconstruction) site meeting shall be held between the Contractor and the Government prior to start of construction activities, see Task 1 – Mobilization.

The meeting shall include, at a minimum:

• Review of project scope and schedule

• Identification of full-depth repair areas

• Discussion of traffic control, site access, and staging
