SECTION C - DESCRIPTION/SPECIFICATIONS/STATEMENT OF WORK

Scope of Contract

Pagosa Job Corps CXT Install, Connection Lines, and Site Work.

This project is related to potable water application and sewer line construction. Therefore, all materials used in the drinking-waterline construction, including drain lines shall be NSF Standard 61 and AWWA C-901 approved for potable water applications.

All work shall comply with applicable federal, state, and local building codes.

CXT Building

This item will include all materials, equipment, and labor to install a prefabricated Forest Service supplied shower and toilet facility. The make and model of this building is the Rainier from CXT, Inc. The building has a footprint of 10’-6” by 23’-8”, stands 10’-2” high, and contains 2 showers, 2 toilets, and 2 sinks. The building requires connection lines to the current drinking water tap (which will also be required to be upsized to 3”), the electrical junction box, and the septic tank located on site. See attachment 11 – USFS Pagosa Job Corps CXT Drawings for an overview of the site and attachment 10 – Prefabricated CXT Drawings for detailed drawings on the CXT. The future building location can also be seen below in Photo 1 – Building Location.

Waterline Connections

This item will include all materials, equipment, and labor to connect the new CXT building to the existing drinking water system and wastewater system.

The new CXT building will be connected to the current drinking water system through a pressurized 2” high density polyethylene (HDPE) distribution line approximately 110’ in length installed and supplied by the Contractor. The line will be buried approximately 2.5’ deep. The current drinking water tap located northeast of the proposed facility will also have to be upsized from a 2” tap to a 3” to properly accommodate the new building. The photo of the existing tap can be seen below in Photo 2 – Existing Tap.

Photo 2 - Existing Tap

The new CXT building will be tied into the current septic system through a 4” PVC pipe approximately 290 feet in length. The slope of the line shall be between 2% and 3.5% to allow for adequate flow. To achieve this slope, the elevation of the CXT outlet must be approximately 3.5 feet below grade. The new sewer pipe must have at least 2.5’ of coverage in all locations. Cut material from the building excavation may be used as backfill along the length of the pipe and must be adequately compacted. The inlet elevation of the existing septic tank is approximately 2.75’ below grade. To adequately tie into the existing septic tank, the existing inlet pipe and sewer service connection for the eastern most campground will need to be removed and replaced with T-junction. The new sewer line will cross the existing drinking water line in one location (see attachment 11 – USFS Pagosa Job Corps CXT Drawings). To accommodate this cross over, the contractor must encase the 4” PVC sewer line inside a 6” x 20’ ductile iron pipe sleeve.

All waterlines shall be tied in to drain to existing drains. All new pipeline and fittings shall be verified free from leaks by the contractor with appropriate testing methods. A photo of the proposed sewer connection line can be seen below in Photo 3 – Future Sewer Connection (North) and Photo 4 – Future Sewer Connection (South).

Electrical Connections

The new prefabricated CXT must be connected into the junction box located on site. The building will need to connect to a 200 AMP disconnect from the main junction box. Electrical conduit and wire must be run from the building to the exiting pedestal approximately 50’ away to the East using a 3” conduit. Within the building, the contractor must provide a 100 AMP disconnect with 240V and 65 AMP electrical box for the water heater. See attachment 10 – Prefabricated CXT Drawings for more details.

Site Work

The Contractor is required to excavate approximately 105 CY of soil for the CXT building install to get the sewer pipe to the appropriate elevation. The CXT building also requires a properly prepared 6” thick sub-base comprised of ¾” minus crushed rock compacted to 95% of optimum density according to ASTM D 1557 with a 2’ buffer around the footprint of the building. This will be approximately 17 CY of material. All grade from the building must be out sloped to allow for proper storm drainage of the site.

The contractor is also required to install two ADA compliant walkways, 3’ in width going from each side of the main road to the entrance of the bathroom facility and 5’ around the building to the North side. The total area of the walkways will be approximately 785 sq. ft. The walkways will consist of pea gravel material 2” thick (for a total of approximately 5 CY of material). See attachment 11 – USFS Pagosa Job Corps CXT Drawings for more details.

All material will be provided by the Contractor besides the Forest Service supplied CXT building. The contractor will be responsible for repairing any damage to Forest Service owned property or utilities, which was caused because of trenching, installing water lines, and other subcontractor activities.

Location of Project

The project is located at the Pagosa Job Corps Center along Piedra Road. From the town of Pagosa Springs, CO, go west on HWY 160 for approximately 2.2 miles. Take a right turn onto Piedra Road (CR 600) and head North for approximately 3 miles. The Pagosa Job Corps Work Center will be on the right-hand side. The physical address of the site is 1589 USFS 654.B, Pagosa Springs, CO 81147. and the coordinates are 37.304266, -107.101709.
