PART 1 GENERAL

1.01 PROJECT

A. Project Name: The Pocket Recreation Area Group Picnic Shelter CXT Installation.

B. Chattahoochee-Oconee National Forests's Name: Chattahoochee-Oconee National Forest.

C. This project involves pre-construction, demolition, and reconstruction at a toilet site located at the Pocket Day Use Group Picnic Shelter Area.

Bidders are urged to make a site visit prior to bidding.

The Contractor shall provide all materials, tools, transportation, labor, proper personnel and environmental protection to successfully complete the project. Proper signage shall be placed, and precautionary measures shall be taken by the Contractor to insure the safety of employees and visitors to the Recreation Area.

The work consists of:

Phase 1:

• Installation and maintenance of erosion control measures for demolition and construction at the site throughout the life of the project/contract.

• Removal, thinning, and disposition of vegetation at direction of COR

• Grading at the direction of COR

• Demolition of an existing toilet, toilet vaults, and concrete pad

Phase 2:

• Reconstruction of the area immediately surrounding a new CXT toilet that has been emplaced by others.

• Reconstruction shall include sidewalk construction and finalization of erosion control measures.

• Finalization of erosion control measures.

Extreme care shall be taken by the Contractor to prevent damage to existing paving. Any damage caused by the Contractor shall be repaired at the Contractor’s expense as directed by the Contracting Officer’s Representative (C.O.R.).

The Contractor shall insure that the job site is left in a clean, neat, and safe condition on a daily basis throughout the life of the project.

SITE SPECIFICS:

The Pocket Recreation Area Group Picnic Shelter is located on the Conasauga District of the Chattahoochee-Oconee National Forest, in the northeast corner of Floyd County. To get to the Pocket, take Georgia 136 east from LaFayette, Georgia, for 13.5 miles; 0.5 mile east of Villanow, turn right (south) on Georgia 156 and proceed about 7 miles to the Pocket Recreation Area. Take the second entrance, Forest Service Road 106, and go to the end of the road which is the parking lot for the Group Picnic Area. Go up to the Group Picnic Shelter and there you will find a concrete sidewalk which leads to an existing toilet building. This is the building which will be removed and replaced.

CXT Installation 01100 - 2 THE POCKET RECREATION AREA

Existing toilet to be removed, sidewalk to be removed, and entry road into area to be widened

PHASE 1:

• Install 460 LF of two rows (920 LF total) of Type C Silt Fence along paved roadway as shown on plans.

Work to be done before any demolition, grading or vegetation removal begins.

• Install Construction Exit that will be 20 feet wide and 100 feet in length, use #4 course aggregate, per detail on plans. Work to be done before any demolition, grading or vegetation removal begins.

• Install 120 LF Tree Save Fence along and 10 feet distant from the Construction Exit on the uphill side of the access roadway. Work to be done before any demolition, grading or vegetation removal begins.

• Widen the gravel access road by approximately 8 additional feet of width on the uphill side of the roadway to existing toilet. The roadway is 120 feet in length. Limb up any remaining trees that overhang this area to a height of 20 feet.

• Clear mid-story and understory vegetation surrounding the toilet building area as directed by COR.

Approximately 0.5 acre will be thinned.

• Strip and stockpile topsoil around the existing toilet building. Topsoil is to be stockpiled to complete final grading of areas.

• Demolish existing toilet building. The building is approximately 8’ x 14’; the interior is polyethylene walls and floor and the exterior is cedar lap & batt with cedar shakes. Remove from FS land.

• Demolish concrete slab surrounding toilet, approximately 20’ x 24’, and 10 additional feet of 5’ wide concrete sidewalk and remove from FS land.

• Pump contents of two existing septic vaults/tanks and clean inside with 10% bleach/water solution.

• Remove and dispose of the two 750 gallon polyethylene vaults/tanks, each 325 pounds. Remove from FS land.

• Backfill hole with soil. Fill material shall be free of brush, rubbish, rocks, logs and stumps. Compact each

12 inch lift of fill and top with 6 inches of topsoil.

• Grade area around toilet to prepare site for the installation of the new toilet.

• Stabilize disturbed areas with mulching only. Organic material from clearing of mid-story and understory vegetation should remain on site and be chipped and applied as mulch if possible. Wood waste should be applied at a depth of 2” to 3” or 6 to 9 ton/acre.

• All disturbed areas shall be left with a neat appropriate temporary protective cover.

PHASE 2:

1. The second phase will not begin until the CXT toilet has been installed by others. Then work can begin on completion of the site improvements.

2. Maintain erosion control measures and Tree Save Fence erosion control measures. Replace if necessary.

3. Construct concrete walkway areas. The toilet building will have 5’wide x 72’ x 4” deep concrete walkway that abuts it on all four sides and an additional 5’wide x 10’ x 4” concrete walkway that adjoins the existing sidewalk. The side walk should have a cross-slope of 2% maximum and a running slope of 5% maximum to make it Accessible.

CXT Installation 01100 - 3 THE POCKET RECREATION AREA

4. Install final erosion control measures. Disturbed area stabilization of Ds3 around new toilet is about 0.05 acres.

5. Remove Tree Save Fencing at end of project and remove silt fence at direction of COR.

6. All disturbed areas shall be left with a neat appropriate temporary protective cover.

1. Install welded wire fabric in lengths as long as practicable; lap at least one full mesh, and lace splices with wire.

D. Joints: Locate and install construction, isolation, contraction, and expansion joints as indicated.

E. Concrete Placement: Comply with recommendations in ACI 304R for measuring, mixing, transporting, and placing concrete. Place concrete in a continuous operation within planned joints or sections.

1. Moisten sub base to provide a uniform dampened condition at time concrete is placed.

2. Consolidate concrete by mechanical vibrating equipment supplemented by hand spading, rodding, or tamping according to recommendations in ACI 309R.

3. Screed and initial-float concrete surfaces with darby or bull float before excess moisture or bleed water appears on the surface.

CXT Installation 04751 - 4 THE POCKET RECREATION AREA before float finishing.

3.2 FINISHES AND CURING

A. Float Finish: Begin the second floating operation when bleed-water sheen has disap-peared and the concrete surface has stiffened sufficiently to permit operations. Float surfaces to true planes with gaps below 10-foot- (3-m-) long, unleveled straightedge not to exceed 1/4 inch (6 mm). Cut down high spots, and fill low spots. Refloat sur-face immediately to uniform granular texture.

1. Medium-to-Coarse-Textured Broom Finish: Provide a coarse finish by striating float-finished concrete surface 1/16 to 1/8 inch (1.6 to 3 mm) deep with a stiff-bristled broom, perpendicular to line of traffic.

B. Curing: Begin curing after finishing concrete, but not before free water has disap-peared from concrete surface. Cure concrete by one or a combination of the following methods:

1. Moisture cure concrete by water, continuous fog spray, continuously wet ab-sorptive cover, or by moisture-retaining-cover curing. Keep surfaces conti-nuously moist for not less than seven days.

2. Curing Compound: Apply uniformly in continuous operation by power spray or roller according to manufacturer's written instructions.
