STATEMENT OF WORK (SOW)

35. BACKGROUND

Mojave National Preserve is located in Eastern San Bernardino County 2 hours east of Barstow, CA. The work site is 30 miles north of Essex, CA on Black Canyon Road at the Hole in the Wall Interagency Fire Center.

2. OBJECTIVES:

This project his project will replace a leaking pipeline, gate valves, stand pipes, Pressure Reducing Valves (PRV), Air Release Valves (ARV), and flow meters, and remove unnecessary hydrants, ARV valves, and stand pipes that are non-functional.

3. PLACE OF PERFORMANCE:

Well 8K1, Section 8, Township 11 N, Range 15 E, San Bernardino County, CA

Permitted Work Hours: Monday through Friday, 7:00am – 5:00pm

4. PERIOD OF PERFORMANCE:

All tasks and deliverables for this contract must be completed within 120 days after Notice to proceed. Days listed herein refer to calendar days.

5. SCOPE:

Approximately 3600 linear feet of potable water pipe will be replaced along with gate valves, standpipes, Pressure Reducing Valves (PRV), Air Release Valves (ARV), and water flow meters. Unnecessary hydrants, ARV valves, and standpipes that are non-functional will be removed. Valve boxes will be reset to grade and enclosed in concrete aprons. Some portions of the water distribution pipe have never been replaced or have had so many repairs they are a nuisance to the park and need replacement. Many of the valves are legacy from a water system upgrade in 2003. Many valves have become below grade over time as the grade shifted over the years from erosion. Several flow meters do not work and make it difficult to identify unusual usage patterns that indicate leaks in the system. Many of the components such as blow off valves and air release valves have not functioned in years and are now a liability to the system.

The original design had an overabundance of yard hydrants very close together and created a large amount of maintenance to keep them operating. This project will reduce the number to a minimum level that will achieve the desired visitor experience. As a Contract Option, exercised at the discretion of the government per the Solicitation, is the installation of approximately 5,000 linear feet of potable water pipe to replace the legacy water line connecting the production water well (existing Well 8K1 & new Well 8K2) to the chlorination building and the existing 30,000 gallon water storage tank’s inlet line.

The 6-inch schedule 40 galvanized steel pipe must be centered in a 12-inch diameter concrete anchor having a depth of 40 inches below the ground surface.

The steel bollard must have 3 inches of concrete cover around and below the section embedded in the concrete anchor. The inside annular volume of the 42-inch section of the steel bollard above the ground must be filled with concrete and domed at the top ½ inch above the steel pipe to prevent standing water. The exterior of the section of the steel bollard extending above the ground surface must be painted with AASHTO approved safety white reflective paint for exterior metal surfaces.

N. Native soil free of rocks, organic material, and debris may be used for backfill. Place backfill materials in horizontal layers not exceeding 8 inches in loose depth. Compact each layer, at optimum moisture content to a density equal to surrounding ground. Above and below the pipe a minimum of 6-inches must be Sieve Size Percent Passing, 1/2-inch 100%, No. 4 50- 80%, No. 40 10- 25%. Note: If the native soil meets these sieve size requirements, then bedding under the water line is not required.

O. Trenching Guidelines: Excavate the trench to the approximate level of the top of the utility line to be installed, using adequate trench width and side slopes to safely accommodate worker access. Continue excavating for the utility line, to a width not greater than is shown on the appropriate trench detail in Chapter 7 Underground Installation of PE piping, Plastic Pipe Institute (plasticpipe.org.) Note: Trenching done by wheel or chain techniques can excavate directly to the required depth to install the water line when their trench width is just slightly wider than the OD of the water line being installed.

1. Rocky Trench Bottom: Where ledge rock, hard pan, boulders, or sharp-edged materials are encountered, over-excavate a minimum depth of 6 inches below the bottom of the utility exterior wall to permit adequate bedding preparation. The installed utility shall have at least 6 inches of clearance from any rock protrusion.

2. Unstable Trench Bottom: Secure approval of depth of over-excavation and stabilization method. For wet trench construction, use approved method of dewatering through diversion, damming and pumping, well points, or underdrain systems. Dispose of removed fluidized materials as approved. Use select backfill material to build a suitable foundation to within 6 inches of finished utility grade, prior to bedding with the specified material. Do not proceed with utility installation until wet trench and unstable conditions are under control.

3. Trench depth for water line installation in the roadway is 30 inches to top of pipe and non-roadway 24 inches to top of pipe.

P. Shoring and sheeting: Construct and maintain all shoring, sheeting, and slope lay-back necessary to protect the excavation, as needed for the safety of the employees and as required by applicable State and Federal laws.

1. For trenches over 5 feet deep, provide suitable barricades for worker protection.

When work area is left open and unattended by Contractor, provide suitable barricades for public safety, regardless of trench depth.

2. For trenches over 4 feet deep, provide suitable exit means in accordance with applicable provisions of OSHA.

3. Do not remove timber or sheeting if it is in a compacted zone. Instead, trim it off at a safe level above that zone.

4. As directed, remove all other sheeting and shoring when safe to do so.

Q. Compaction: Use vibratory compactors for sands and gravels (non-cohesive soils). Use mechanical tampers for sand and gravel containing a significant portion of fine-grained material, such as silt and clay (cohesive soils). Hand tamp around pipe, conduit, or cable to protect the lines until adequate cushion is attained. Puddling or water flooding for consolidation of backfill or compaction by wheel rolling with construction equipment will not be permitted.

R. Utility Installation: Shape the trench bottom to ensure uniform contact with the full length of the installed line and remove any sharp-edged materials that might damage the line.

Compaction shall be maintained beneath the line.

1. Select Backfill: Fill by hand placement around the utility to just over half depth, and compact in a manner to ensure against lateral or vertical displacement. Place select backfill to 12 inches above the utility line by hand placement in not more than 6-inch layers.

2. Vehicular Traffic Areas: Fill and compact in 8-inch maximum layers to 95 percent of maximum density.

3. Nontraffic Areas: Fill and compact in 8-inch maximum layers to 90 percent of maximum density.

4. When chain or wheel trenching techniques are used, the trench width need only be slightly wider than the OD of the water line being installed.

S. Pressure-Test of Pipe System: Hydrostatic pressure leak tests of new PE pressure piping systems (once the water line is installed, and all isolation valves, PRVs, hydrants, combination air valves, and associated appurtenances have also been installed) must be conducted in strict accordance with ASTM International F 2164, Standard Practice for Field Leak Testing of Polyethylene (PE) Pressure Piping Systems Using Hydrostatic Pressure.

1. Pneumatic pressure testing of any water piping system is prohibited in Mojave National Preserve.

2. Where any isolation valves, PRVs, hydrants, combination air valves, and associated appurtenances are installed on the existing water system, a visual leak detection test must be conducted for two (2) hours at the normal working pressure of the water system prior to backfilling. Any detected leakage constitutes a failure of the visual leak test and repairs must be made to eliminate the detected leak.

T. Disinfection of Pipe System: The AWWA C651 (latest edition) Standard for Disinfection of

Water Mains must be adhered to for water system features installed.

U. Plugging of Abandoned Water Line: Legacy water lines that are designated to be abandoned in place once new water lines have been installed (and are in beneficial use where required) must be disconnected from the water system and plugged using non-shrink cement grout.

The plug must fill a minimum of six-inches inside the abandoned pipe from the cut end of the pipe.

13. OTHER REQUIREMENTS:

A. Contractors will receive Desert Tortoise training. Work conducted during active tortoise season will require a monitor.

B. Archeological Monitor shall have access to observe all ground-disturbing site work, including construction of temporary facilities, from a safe location mutually agreed on by Contractor and Monitor.
