INSTALLATION

Installation Method

The HDPE pipe shall be installed using the horizontal directional drilling method as per Carmel Utility Standards practices noted below. Locations where pipe material transitions are required i.e. (HDPE/DIP) may be installed by open cut.

Pipe Joining

1. The HDPE pipe shall be assembled and joined at the site using the butt-fusion method to provide a leak proof joint. Threaded or solvent-cement joints and connections are not permitted. All equipment and procedures used shall be used in strict compliance with the manufacturer’s recommendations. Fusing shall be accomplished by personnel trained as fusion technicians by a manufacturer of polyethylene pipe and/or fusing equipment.

2. Square the pipe ends by using the fusion machine facing tool. In the fusion machine, pipe ends shall meet squarely so that the entire area to be fused is covered. The pipe ends shall make firm contact without applying pressure to the heat plate. The heat plate temperature shall be as required by the pipe manufacturer's recommendations. The melt bead shall be according to pipe diameter and as recommended by the pipe manufacturer. Pipe ends shall be carefully moved away from heat plate once the appropriate melt bead is achieved.

The pipe ends shall be joined quickly without slamming. The butt-fused joint shall be true alignment and shall have uniform roll back beads resulting from the use of proper temperature and pressure. The joint shall be allowed adequate cooling time before removal of pressure. The fused joint shall be watertight and shall have tensile strength equal to that of the pipe. All joints shall be subject to acceptance by the OWNER prior to insertion.

3. All defective joints shall be cut out and replaced at no cost to the Owner. Any section of the pipe with a gash, blister, abrasion, nick, scar, or other deleterious fault greater in depth than ten percent (10%) of the wall thickness, shall not be used and must be removed from the site. However, a defective area of the pipe may be cut out and the joint fused in accordance with procedures stated above. In addition, any section of pipe having other defects such as concentrated ridges, discoloration, excessive spot roughness, pitting, variable wall thickness or any other defect of manufacturing or handling as determined by the OWNER and/or the project representative shall be discarded and not used.

Pressure Testing

1. Under no circumstances shall HDPE pipe be pressure tested when the temperature of the pipe is above 80 degrees Fahrenheit.

2. HDPE pipe holds pressure by developing stress in its walls, thus the pipe will increase slightly in diameter when under high pressures. The procedure for pressure testing HDPE main should take in account the expansion of the HDPE main. The recommended procedure is to:

a. Initially pressurize the main to the standard test pressure (150 psi) and let a majority of the main expansion take place, which should occur in 2 – 3 hours.

b. After the above expansion time period, the main should be pressurized again to test pressure (150 psi) and the Pressure Test is conducted for the two (2) hour period. The HDPE pipe will continue to expand during the test itself and the following table contains maximum allowances for this expansion.

OWNER and after a determination is made that the chemicals to be added are not harmful or corrosive to the facility and are environmentally safe.

B. The Contractor shall identify the source of fresh water for mixing the drilling mud. The

Contractor shall be responsible for approvals and permits required for such sources as streams, rivers, ponds, or fire hydrants. Any water source other than potable water may require a pH Test.

C. Monitoring of the drilling fluids such as the pumping rate, pressures, viscosity, and density is required during the pilot bore, back reaming, and pipe installation stages, to ensure adequate removal of soil cuttings and the stability of the bore hole. Relief holes can be used as necessary to relieve excess pressure down hole. To minimize heaving during pullback, the pull back rate is determined in order to maximize the removal of soil cuttings without building excess down hole pressure. Excess drilling fluids shall be contained at entry and exit points until they are recycled or removed from the site.

Entry and exit pits shall be of sufficient size to contain the expected return of drilling fluids and soil cuttings.

D. The Contractor shall ensure that all drilling fluids are disposed of or recycled in a manner acceptable to the appropriate local, state, or federal regulatory agencies. When drilling in suspected contaminated ground, the drilling fluid shall be tested for contamination and disposed of appropriately. Any excess material shall be removed upon completion of the bore.

E. Restoration for damage to any transportation facility or non-transportation facility caused by heaving, settlement, escaping drilling fluid (fracout) or the directional drilling operation, is the responsibility of the Contractor. Any pavement heaving or settlement damage requires restoration/replacement of the pavement per applicable

City standards.

PART 3 EXECUTION

3.1 GENERAL CONSTRUCTION REQUIREMENTS
