Do not allow water to accumulate in excavations. Remove water using dewatering methods to prevent soil changes detrimental to stability of subgrades. Convey water removed from excavations and rain water to collecting or runoff areas. Provide and maintain temporary drainage ditches and other diversions outside excavation limits for each area. Remove and replace, or scarify and air dry, soil material that is too wet to permit compaction to specified density. Soil material that has been removed because it is too wet to permit com- paction may be stockpiled or spread where directed by Engineer and permitted to dry. Assist drying by discing, harrowing, or pulverizing, until moisture content is reduced to a satisfactory value, as determined by moisture- density relation tests. When accepted by Engineer, soil material may be used as fill.

Trenches shall be backfilled even with subgrade (or surrounding grade), raised to a slight mound and rolled with a 250 pound roller or with an approved compactor or vibrator. Lifts shall be 6" maximum. All roots, rocks and surplus excavation shall be removed from the site. The Contrac- tor is responsible for all trench settlement during the warranty period of this Contract. Where laterals exist under the sand portion of the field, laterals may be laid in drain trenches where applicable. See Plan. 3.02 AUTOMATIC VALVES (ADD ALTERNATE #4) Automatic valves shall be installed in "Jumbo" valve boxes, per the specifications. Provide galvanized ground -joint union on the inlet side. Flush supply lines before installing automatic valves. Use valve box extensions to ensure that box extends completely below bottom of valve. See detail. 3.03 PIPE AND FITTINGS PVC pipe ends shall be cut at 90 degree to the pipe length and cleaned of all cutting burrs prior to cementing. Use approved reaming tool. Pipe ends shall be wiped clean with a rag lightly wetted with PVC thinner. Cement shall be applied with a light coat on the inside of the fitting and a heavier coat on the outside of the pipe. Pipe shall be inserted into the fitting and given a quarter turn to seat the cement. Excess cement shall be wiped from the outside of the pipe. Pipe will be tested as indi- cated elsewhere in these specifications. No backfilling will be permitted other than at the centers of pipe lengths until the pressure test is com- plete. Solvent weld joints shall be given at least 15 minutes set -up time before moving or handling. Pipe shall be partially center - loaded to prevent arching or slipping. No water shall be permitted in the pipe until a period of at least 10 hours has elapsed for solvent weld set and cure. Backfilling shall be done when the pipe is not in an expanded condition due to heat or pressure. Cooling of the pipe can be accomplished by operating the system for a short period of time before backfilling, or by backfilling in the early part of the morning before the heat of the day. IRRIGATION SECTION 02450 PAGE 5 3.03 PIPE AND FITTINGS, continued Before pressure testing, solvent weld joints shall be given at least 24 hours cure time. Triple swing joints'shall be assembled with two wraps of "teflon" type tape at each connection. When assembled, joint shall be watertight but capable of being adjusted up or down. Great care shall be taken to ensure that the inside of the pipe is abso- lutely clean. Any pipe ends not being worked must be protected and not left open. Cleaning of cutting burrs is MANDATORY. 3.04 DOUBLE CHECK VALVE ASSEMBLY DC assembly is existing. Adapt to exit of DC assembly for new galvanized pipe connection to QC valve (for winterization). Install QC valve with two galvanized ground -joint unions in such a manner that a later instal- lation of a 2" pressure reducing valve will be simple. 3.05 GALVANIZED PIPE AND FITTINGS All buried galvanized pipe, including valve fittings, shall be painted with at least one coat of "Carbon Elastic Paint" to prevent acid corrosion. Do not add any solvent to the paint. If the paint is too thick, heat with- out applying direct flames. Care must be taken to thoroughly paint all male threads. When paint is done before assembly, the paint shall be touched up after assembly. 3.06 CONTROL WIRES Control wires are to be taped together at 10 feet intervals; then, this bundle is to be taped to the bottom of the supply main at 10 foot inter- vals with at least three wraps of electrical tape. Where no control wire is in a trench, install one #14 bare copper locater wire,,taped to pipe; this includes mains and laterals. All splices must be encapsulated in the device specified in the paragraph for "Electrical Wire Splices ". All splices must be contained in a plastic valve box where a future valve is proposed. No splices are permitted be- tween the proposed valve location and the westerly terminal box shown on the plans. There must be a separate "hot" lead for each future automatic valve. One common wire may be used to reach all future valves. One unconnected spare control wire is to be installed from the controller to each of the following locations on the project: From Terminus to Valve V -1 From Terminus to Valve V -3 Install auxiliary wires to pass through each intermediate valve box and to loop at least 24 inches of the wire in a coil as it passes through that intermediate box. An additional "loop box" shall be installed with a 24" wire coil near future Valve V -6. Minimum size of copper wire for this project is #14 UF. The control wires shall be color coded as follows: IRRIGATION SECTION 02450 PAGE 6 3.06 CONTROL WIRES, continued Control wires: • Neutral (Common) Wire: White Hot Wire: Red (or black) Auxiliary Wire: Orange 3.07 MAIN LINE Install minimum of 24 inches below finish grade except where main line is located in drainage trench install minimum of 15 inches below finish grade. 3.08 SERVICE CUT -IN Connect to existing 2" DC valve and existing meter as shown on the plans. See cut -in detail. 3.09 AUTOMATIC CONTROLLER (ADD ALTERNATE #4) Location and source of 110 volt service to be determined at the time of automation. 3.10 REMOTE CONTROL DEVICE (ADD ALTERNATE #4) Install adjacent to the irrigation controller. Anchor to controller in a A manner that will permit easy connect and disconnect of the TRC receiver and allow for antenna extension. 3.11 SYSTEM FLUSHING The entire system shall be flushed prior to the installation of the sprink- ler heads. After capping all risers, Contractor shall remove the cap nearest the meter, flush and recap. Repeat this process until the last head on the system is flushed. 3.12 PRESSURE TEST All system joints, connection, etc., shall be left exposed until after completion and acceptance of the pressure test. Entire system shall be capped and pressurized to 200 psi for a period of one hour. All joints and connections shall be checked visually for leaks. All leaks, however, minor, shall be repaired and corrected. Owner shall be present during the test(s). Contractor has the option to test by pressure drop method (pipe not required to be exposed). If Contractor so elects, line shall be pressurized to 150 psi with a drop not exceeding 5 psi in 15 minutes. Perform with pressure testing pump that has been approved by the Engineer. 4.14 PERFORMANCE TESTS (ADD ALTERNATE #4) Upon completion of the system installation and after the flushing and pressure tests have been completed, the Contractor shall operate the sys- tem in the presence of the Owner and Engineer. System shall be tested for manual, semi- automitic and fully automatic operation. 3.15 FINAL APPROVAL Upon completion of all tests, final approval for the system will be con- tingent upon Contractor providing signed and approved sprinkler /plumbing/ health /electrical permits as may be applicable in Tukwila.
