Project Name South Fork Bunkhouse Well Replacement, Rio Grand National Forest, South Fork, Colorado.

General Information

1.0 Scope of Work

The Rio Grande National Forest is seeking a Contractor to drill and develop a new potable water well, perform all necessary water quality analysis for use as a Public Water System, install an existing submersible pump and installation of a new pump control panel and all wiring and appurtenances. The Government shall provide a trench, waterlines, and power to the new well once the well has been successfully developed. The Contractor shall connect the new waterlines to the existing water lines and the new wellhead. The purpose of the main contract items is to ensure the current private water system remains supplied with potable water and that the system can continue to adhere to the regulations and requirements of a Public Water System.

Optional items will include provisions for well construction and development beyond the depth estimated and a new submersible pump should the existing pump be inadequate for use in the newly constructed well.

Project Location: The project location is located within the town of South Fork, Colorado, 37°38'15.4"N 106°39'36.7"W.

2.0 Background

In the town of South Fork, Colorado the Rio Grande National Forest operates a private water system consisting of a bunkhouse and ancillary dwelling with an existing well that supplies the ancillary dwelling with water, which contains the current water supply pressure tank, and then supplies the bunkhouse with water. The current well is 120 feet deep and is located as specified on Form GWS-44. The well replacement permit stipulates a maximum pumping rate of 15 gallons per minute and has an annual yield of 3 acre-feet from an unconfined aquifer (Type II).

BID ITEMS

BID ITEM 1 Mobilization includes bonding

BID ITEM 2 Well Construction and Development 2.1: The Contractor shall provide all materials, labor, equipment, tools, transportation, permits, licenses, supervision, expertise, and other incidentals necessary to successfully construct a new functioning potable water supply well in accordance with all the rules described in the Colorado Code of Regulations (CCR) - Colorado Division of Water Resources - Well Construction Rules 2 CCR-402-2 (NOTE: The Contractor shall adhere to all the rules described in these regulations whether mentioned specifically or not.)

The well shall conform to 2 CCR-402-2 Rule 10 Section 10.4.6 for Wells Constructed into a Type 2 Aquifer as stated on the Well Permit Application. It shall be of the pitless adapter Type, and the casing shall extend a minimum of 18 inches above ground level. The newly constructed wellhead and casing shall be protected by a hinged steel enclosure (i.e. stick-up or monument) capable of being locked with a standard government padlock and allows for maintenance of the well and wellhead components.

2.3: The Contractor shall install and construct the well in accordance with the specifications, drawings, and applicable manufacturer’s recommendations.

2.4 The Contractor shall salvage the existing submersible pump from the existing well to be used in the newly constructed well. The Contractor shall furnish and install all necessary piping, check valves, and wiring for the existing submersible pump to function in the newly constructed well.

2.5: The newly constructed well shall have a yield of 15 gallons-per-minute and an annual yield of 3 acre-feet.

2.6: The Government has estimated the new well to be 150 feet in depth for bidding purposes. The Bid quantity shall be in linear feet and include all necessary casing material, grouting material and wiring required to reach well development depth. The Contractor shall provide pricing per linear foot. This pricing shall also be used for Option Item 1001 Additional Well Construction Depth, to ensure well development if additional construction beyond 15% of the specified depth is required. (FAR 52.211-18 Variation in Estimated Quantity)

2.7: The Contractor shall develop the well and install the casing and all necessary grouting in a timely manner to avoid the possibility of a borehole collapse.

2.8: The Contractor shall install all materials and appurtenances in accordance with the manufacturer's specifications and recommendations. The Contractor shall submit specifications of the well casing, capping, vent, enclosure, and grouting materials prior to the construction and development of the well.

2.9: The Contractor shall perform disinfection procedures according to 2 CCR-402-2 Rule 15 Minimum Disinfection Standards.

2.10: The Contractor shall install the well at no more than 200 feet from the location specified in the well replacement permit:

37°38'15.4"N 106°39'36.7"W. The Contractor shall coordinate with COR on the specific placement of the well within the 200 foot radius.

2.11: The Contractor shall conduct testing according to 2 CCR-402-2 Rule 12 Well Testing and submit a Well Construction and Yield Estimate Report (GWS-31) to the Colorado Division of Water Resources to verify well construction.

2.12: The Contractor shall be responsible for the remediation of any failed wells that do not meet the requirements described in the specifications of this contract.

2.13: The Contractor shall utilize the Government supplied water lines and power conduit to complete the connections between the newly constructed well and the existing water supply pressure tank water lines. The Contractor shall furnish and install the necessary additional power conduit, water lines, and equipment to complete this task.

BID ITEM 3 Water Quality Analysis and Testing 3.1: The Contractor shall perform National Primary and Secondary Contaminants and laboratory analysis of water quality per EPA, Safe Drinking Water Act, and the Colorado Code of Regulations – 5 CCR 1002-11 Colorado Primary Drinking Water Regulations.

3.2: The Contractor shall perform all the necessary tests and documentation to bring the newly constructed well into compliance consistent with a Public Water System (PWS) (but shall remain classified as a private water system) as outlined in the Colorado Code of Regulations.

3.3: The Contractor shall submit the results of the water quality analysis tests to the Government and all applicable Colorado State Water Authorities in a timely manner once results are received.

BID ITEM 4 Submersible Pump Controller Unit and Wiring 4.1: The Contractor shall provide all materials and expertise to install a new submersible pump control panel in the ancillary bunkhouse building containing the current water pressure supply tank and all necessary wiring, conduit, switches, grounding, and trenching to function properly.

4.2: The Contractor shall submit the pump control panel model, manufacturer’s specifications, documentation, and manuals prior to the installation of the pump control panel.

4.3: The Contractor shall ensure compatibility with the existing submersible pump and a new submersible pump model of equivalent specifications.

OPTIONAL BID ITEMS 1001

BID ITEM 1 Additional Well Construction Depth 1.1: If the Contractor cannot develop or construct a well with a viable water source at or near the specified 150 feet in depth, The Contractor shall bid per-foot depth beyond the 150 feet until a viable water source suitable for development is reached, not to exceed 200 feet total well depth.

1.2: The Contractor shall be responsible for the remediation of the well if a viable water source cannot be located for development up to the 200 feet.

BID ITEM 2 New Submersible Pump 2.1: The Contractor shall furnish and install a submersible pump and all associated pump wiring, fittings, conduit, and control panel to transmit water from the new well source to the water supply pressure tank.

2.2: Pump appurtenances, wiring, conduit, and their quantities shall be considered incidental to this bid item.

2.3: The Contractor shall field verify quantities of wiring, conduit, and quantities of materials prior to installation of the pump and related appurtenances.
