1.8 – Special Construction Requirements

Upon completion of the project, all demolished improvements and other construction materials shall become the property of the Contractor and be removed from

Government land and/or disposed of in accordance with State and County standards.

Construction Access and Protection: The Contractor shall be responsible for securing the project area from the public. This includes providing the necessary security for protection of the Contractor's materials, equipment, tools and work until final acceptance by the Government.

The roadways to and within some of the project sites are narrow and windy, with abrupt curves and widths that vary. As such, mobilizing large equipment to the construction sites will likely require additional efforts to navigate these roads. Smaller dump trucks, concrete trucks, and standard width vehicles have accessed the site with no problems.

If campgrounds are open during construction, it is the Contractor’s responsibility to take appropriate care (such as the use of fencing) to protect the public from possibly injury from site activities.

Equipment and material storage: The Contractor shall obtain permission from the

Contracting Officer for equipment and material storage, and for other areas needed for construction. The safety and security of the Contractor’s equipment and materials is not guaranteed by the Government.

All site features to remain shall be protected from damage during the project.

No live trees are to be cut without permission from the COR. Tree limbs may be trimmed as necessary.

Sanitation/Garbage: No garbage service is available for Contractor use. The Contractor shall keep the construction site free of loose garbage at all times.

Campground or nearby restroom facilities will be made available for Contractor use.

The project will be implemented with the following Best Management Practices:

1. During servicing or refueling of equipment, vehicles, and machinery, there is a potential for pollutants to enter a watercourse. This threat will be minimized by locating service and refueling areas well away from Sabino Creek in an upland setting. The contractor will be required to have a Spill Prevention, Control and

Countermeasures Plan in place.

2. Loose, unconsolidated sidecast material will not be allowed to enter streamside management zones. The contractor will use wattles and or silt screens to prevent movement of disturbed soil into the stream. Wattles will be certified "weed

Free".

3. Sidecasting, the piling of excavated dirt on the edge of a ditch, or elsewhere in a wetland or other water of the U.S. will not be an acceptable construction alternative in areas where it will adversely affect water quality. Prior to commencing construction or maintenance activities, waste areas will be located where excess material can be deposited and stabilized.

1.9 – Contract Closeout

Remove temporary facilities and provide final cleaning and touch!up. Restore portions of buildings, site improvements, landscaping, and other items damaged by construction operations to the satisfaction of the Government at no additional expense to the

Government.

B. Stake locations of new water lines as shown on the drawings. The Contracting

Officer (CO) shall approve the water line location prior to the start of excavation.

C. Sections of the water system that operate seasonally shall be constructed to drain by gravity to daylight drains for winter campground shutdown. Waterlines shall be constructed to drain at a minimum grade of 0.5% unless indicated on the drawings.

Waterlines not meeting this requirement shall be removed by the Contactor and replaced at no cost to the Government.

D. Pipelines may be relocated slightly, if necessary, to avoid existing obstacles.

However, seasonally operated lines shall be installed to slope towards drains as shown on the drawings.

E. Deflections from a straight line or grade, as required by vertical curves, horizontal curves, or offsets, shall not exceed the manufacturer's recommended maximum joint deflection or curvature for their pipe. If the alignment requires curvature or deflections in excess of these limitations, the Contractor shall provide special bends, standard fittings, or a sufficient number of shorter lengths of pipe to provide angular deflections at the joints within the limit set forth by the manufacturer.

F. Bends resulting in tension on joints will not be allowed.

3.2 ! General

A. All pipe, fittings, and appurtenances shall be handled and laid in strict conformance to the manufacturer’s recommendations.

B. Drains, valves, and other regulating and controlling devices shall be installed in the line where called for on the drawings.

C. The interior of all pipe, fittings, and other accessories shall be kept as free as possible from dirt and foreign matter at all times. Each piece of line as it is laid shall be cleaned of all debris. When the pipeline has become dirty on the inside during shipment or storage, it shall be swabbed out by drawing a damp swab through the line before lying. Care shall be exercised to keep all joining surfaces clean. Any pipe with contaminated or damaged joining surfaces, which cannot be satisfactorily cleaned or repaired, shall be discarded. Under no circumstances shall pipe be laid in water, and no pipe shall be laid when trench conditions or the weather is unsuitable for such work. At all times when work is not in progress, all open ends of the pipe and fittings shall be securely closed to the satisfaction of the CO so that no trench water, rodents, earth, or other substance will enter the pipe or fittings.

D. Any section of pipe already laid and found to be defective shall be taken up and replaced with new pipe at the Contractor’s expense.

E. Where water line crosses a road culvert, adjust grade of water line to provide a minimum of 12 inches of separation between the water line and culvert, maintaining slope of water line to daylight drain.

F. A minimum of one!foot separation shall be maintained between electric and water lines in the same trench. Unless the electric conductors are in conduit the water line shall be a minimum of one foot below the electric conductors.

G. Bury piping with depth of cover over top at least 24 inches (750 mm), with top at least 12 inches (300 mm) below level of maximum frost penetration.

H. Install underground piping with restrained joints at horizontal and vertical changes in direction. Use restrained!joint piping, thrust blocks, anchors, tie!rods and clamps, and other supports.

3.3 – Excavation, Trenching, and Bedding

A. 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. Any shifting or change from the alignment and grade as staked or as shown on any included drawings must receive prior approval by the COR in writing.

1. Rocky Trench Bottom: Where ledge rock, hard pan, boulders, or sharp!edged materials are encountered, overexcavate 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 material to build a suitable foundation to within 6 inches of finished utility grade, prior to bedding with the specified material. Compact layers to 95 percent of maximum density in not greater than 6!inch layers. Do not proceed with utility installation until wet trench and unstable conditions are under control.

B. Trim roots flush with trench wall.

C. During excavation, material satisfactory for backfilling shall be stockpiled in an orderly manner at a distance from the banks of the trench equal to ½ the depth of the excavation, but in no instance closer than 2 feet. Excavated material not required or not satisfactory for backfill shall be disposed of off!site by the

Contractor, or as directed by the COR.

D. Unauthorized over!excavation shall be backfilled in accordance with the parameters of these specs at no additional cost to the Government.

E. The trench width below the top of the pipe shall not exceed 24 inches plus pipe outside diameter.

F. Notify COR when excavation is completed. Do not place pipe, cable, or begin backfill until the excavation is approved by the COR.

3.4 – Cutting and Handling of Pipe

Cutting of pipe for closure pieces or for other reasons shall be done in a neat manner by methods, which will not damage the pipe. The pipe and fittings shall be handled in such a manner as to insure delivery and final placement in good, undamaged condition.

Particular care shall be exercised not to injure the pipe surfaces or coatings. Damaged pipe shall not be used in the work.

Handle and install pipe in accordance with ASTM F645 and manufacturer’s installation instructions

3.5 – Laying Pipe

A. No pipe shall be placed in the trench until the CO has approved the trench and bedding.

B. Each section of the pipe shall rest upon the pipe bed for the full length of its barrel.

C. Backfill the pipe within 24 hours after installing the pipe in the trench, leaving the joints and one foot of pipe on each side of each joint exposed until testing is complete.

D. When work is not in progress, securely close open ends of pipe and fittings. Keep interior of pipeline and joining surfaces clean.

E. When high density polyethylene pipe is used, it shall be weaved in the trench to provide horizontal slack in the line for expansion and contraction.

F. High density polyethylene pipe shall be allowed to cool to within 20° F of the shaded trench bottom temperature before backfilling.

G. Do not lay pipe in water.

H. Do not exceed the manufacturer’s recommended maximum deflection. Deflections in excess of these limitations require special bends or a sufficient number of shorter pipe lengths.
