A. Scope of Contract The Angeles National Forest has a need to perform demolition of two CXT brand single stall vault toilets located approximately 12 miles north of Azusa California. The toilets were impacted by vehicles and are no longer functional.

Item 001 is located in the lower west fork parking lot (34.2410127, -117.868005).

Item 002 is located on the west side of Highway 39 north of the main West Fork Parking lot (34.2440944, -117.869649). Once demolition is complete there is a need to install two precast concrete vault toilet buildings.

Item 0001 The contractor shall mechanically remove all contents of the vault no more than 3 days prior to structure demolition. A minimum of 50 gallons of water shall be placed in the vault prior to pumping.

This building has not been tested for any regulated hazardous materials, however, based on its age it is not anticipated to contain any hazardous materials such as asbestos, lead, treated wood, or mastic. The contractor shall inspect the building and perform all necessary testing and abatement required by Federal, State, or Local laws and ordinances, including but not limited to: Resource Conservation and Recovery Act, South Coast Air Quality Management District Rule 1403, and Chapter

For the buried portion, the contractor shall chip away and remove the vault structure to a minimum of 1 foot below grade. Each vault structure shall have a minimum of 6 2-inch diameter holes drilled in the bottom surface to facilitate infiltration.

Item 0003 After demolition is completed, contractor shall supply and install a new precast single vault toilet into the same excavation left from completion of Item 0001. Installation shall be to the specifications supplied by the manufacture of precast vault toilet.

Item 0003 shall be a single stall precast concrete vault toilet identified below or equivalent. Equivalent models must be approved by the COR.

Before commencement of work, the Angeles National Forest shall:

1. Provide the contractor the exact placement location by stakes or other approved method.

Before commencement of work, the contractor shall:

1. Ensure the worksite is clear of overhead obstructions which may include clearing vegetation, so the worksite is clear and ready for site preparation.

2. Provide access to the site for truck delivery and sufficient area for the crane to install and the equipment to perform the contract requirements.

The contractor is responsible for all permitting requirements related to this project and traffic control for truck, crane equipment and any delivery vehicle site access required for installation.

C. Technical Specifications The contractor shall provide all labor, materials, equipment, and supplies necessary to complete the tasks listed in the schedule of items.

1. Materials The contractor shall supply:

o Bedding material to be sand or ⅜” minus crushed or screened aggregate.

o Caulking between vault and toilet floor to be 1” x 1” Butyl tape designed specifically to bond precast concrete to precast concrete.

o All materials identified by vault manufacturer to provide for finished vault building installation.

o Cold patch asphalt to establish ABA approach to vault restroom (ITEM 0004).

2. Excavation and Elevation The Contractor shall meet the following:

o Comply with all applicable Occupational Safety and Health Administration (OSHA) standards for excavation.

o Excavate for the installation of the toilet vault to a depth that will allow the structure site to be free draining after installation is completed. Allow for a 2” leveling course beneath the toilet vault. Stockpile topsoil in a separate pile at sites.

o Finish floor elevation is 4-6” above natural grade measured at the front (entrance) of the exterior slab unless otherwise approved by the COR. Ideally, the back of the building should be slightly higher to allow water to freely drain out of the toilet rooms.

o No excavation is to be left open more than seven (7) days unless otherwise approved by the COR.

o All excavations left open overnight are fenced with wire mesh or plastic mesh fence secured to steel posts all around the excavation.

The bottom of the fence will generally follow the contour of the ground.

Maximum spacing of the steel posts is 10’.

Minimum height of the fence is 36”.

3. Backfill and Compaction

The contractor shall:

• Compact the natural ground at the bottom of the vault excavation with a minimum of three (3) passes with a whacker-type mechanical compactor or equivalent approved by the COR.

• Install sand or aggregate bedding material for leveling course if needed. Compact leveling course with one (1) pass with a whacker-type mechanical tamper or equivalent approved by the COR.

Grade leveling course so there are no high spots in the middle of the vault bottom. Compact with a second pass with a whacker or approved equivalent tamper.

• Set vault in place and check for level or appropriate scope. Backfill around structure. Use excavated material for backfill except those rocks larger than 6” in maximum dimension shall not be placed within 6” of the exterior vault walls.

• Fill, adjacent to the building entry, will have excavated material placed in 8” loose lifts and compacted with a minimum of two (2) passes with a whacker-type mechanical compactor of equivalent approved by the COR.

4. Finish Grading The contractor shall:

• Spread excess excavated material from the vault around structure. Intended final grade is flush with the top of the front slab. Allow for placement of topsoil to reach that grade. Grade backfill away from structure at maximum slope of 5% unless otherwise approved by the COR.

• Spread stockpiled topsoil as final layer after rough grading is completed. Areas disturbed by excavation, backfilling and stockpiling of excavated materials are hand raked to remove exposed rocks over 1” in maximum dimension.

• Oversized rocks removed from the surface shall be disposed of in a designated area within 200’ of the site.

D. Work Hours:

Regular work hours are 6:00 am-6:00pm Monday through Friday excluding Federal Holidays.
