This is a set of 100% construction plans for the water line relocation component (Schedule C) of the SW 205th Avenue - Baseline to Quatama Improvements project in Washington County, Oregon, prepared for the Tualatin Valley Water District (TVWD). The project involves the installation of approximately 157 to 243 linear feet of 12-inch ductile iron (DI) water main pipe with restrained mechanical joints, transitioning from existing 8-inch and 12-inch water lines to connect with a 16-inch existing line. Key construction elements include the installation of two 20-inch diameter steel casings, two 12-inch flexible expansion joints, four straddle blocks, two 12-inch butterfly valves, multiple 12-inch DI bends and fittings, a 12-inch by 16-inch reducer, a 2-inch combination air and vacuum valve, and various concrete thrust blocks and pipe supports. The work spans approximately 4,100 linear feet along SW 205th Avenue from Station 37+50 to Station 51+80, with critical sections including bridge crossings at four distinct bents and creek crossing details. The plans detail material specifications requiring class 52 ductile iron cement mortar-lined, zinc-coated, and asphalt seal-coated pipe with 8-mil polyethylene wrap, along with restrained joint systems using megalug restraints or approved equivalents. All materials must be new domestic manufacture with documentation of U.S. origin, and no foreign or rebuilt materials are permitted.

Construction requirements mandate hydrostatic pressure testing at 150 psi for 60 minutes per AWWA C600 standards, with mainline tested in sections not exceeding 1,000 feet, supervised by TVWD staff. Disinfection and flushing must comply with Oregon Health Authority guidelines and DEQ requirements, with two consecutive bacteriological samples collected by TVWD representatives at least 24 hours apart before the system is placed into service. The contractor must provide 5 working days advance notice prior to construction activities, comply with all TVWD engineering design manual standards and Oregon APWA/ODOT specifications, and maintain minimum 10-foot horizontal spacing from sanitary sewers and 12-inch clearance when crossing other utilities. Standard details reference TVWD specifications for valve locations, operator extensions, straddle block design with safety factors of 1.5, polyethylene encasement installation, and trench backfill using class B granular material compacted to 95% of AASHTO T-99 standards within street right-of-way and class A native backfill to 90% outside paved areas. Water service disruptions require two weeks advance notice and may only occur Tuesday through Thursday, 9 a.m. to 3 p.m., unless otherwise approved by TVWD.

1. All construction is to be performed in accordance with specifications for the SW 205th Avenue - Baseline to Quatama Improvements project and the most recent versions of Tualatin Valley Water District (TVWD) engineering design manual and standard drawings, AWWA Standards, and Oregon APWA/ODOT standard specifications.

2. The contractor shall notify TVWD at least 5 days (five full working days) prior to beginning water line construction activities.

3. Operation of existing valves shall only be performed by TVWD staff. Operation of valves in the water system(s) by anyone other than the TVWD staff is strictly prohibited.

4. Water service disruptions (Shutdowns) require 2 weeks advance notice. Shutdowns may only occur Tues-Thurs 9am to 3pm unless otherwise approved by TVWD. TVWD will provide notification to affected water users for planned service disruptions. Connections between existing infrastructure and new work shall not be made until necessary tests and inspections have been completed on the new work and it is found to conform in all respects to the requirements of the plans and specifications.

5. Existing utilities are shown on the plans in approximate locations only. Prior to any excavation, contact the utility locators for marking of underground lines and services, and pothole ahead as needed to find and protect those lines and services. Notify the TVWD representative of any conflicts.

6. While locating and protecting the underground utilities, comply with the regulations of ORS 757.571.

7. Take precautions to protect and maintain existing public and private utility lines and other utility structures. should the utility become damaged, immediately notify the affected utility agency.

8. The contractor shall perform all the work shown on the drawings and all incidental work considered necessary to complete the project in an acceptable manner.

9. Portions of the existing water lines are to be removed as required to install pipe. All pipe 6" in diameter and larger not removed and abandoned in place, is to be plugged, as specified. Plug ends of abandoned smaller mains exposed during construction with grout plug, blind flange, or cap as directed by TVWD.

10. All materials shall be of new manufacture and must be domestic. No rebuilt or used materials will be allowed. All materials shall have documentation providing evidence that the materials used in this construction were manufactured in the United States. No foreign manufactured materials will be allowed.

11. Water main pipe shall be class 52 ductile iron cement mortar-lined, zinc coated and asphalt seal-coated.

All joints shall be restrained with a boltless restraint system, for exposed pipe or pipe inside of casing.

Wrap all buried pipe in 8-mil v-bio enhanced polyethylene. Unless otherwise specified, fittings shall have zinc coating, mechanical joints with megalug joint restraints or approved equal.

12. All material suppliers shall submit to theTVWD representative proof of material(s) tested in accordance with the specifications. The contractor shall certify that all materials delivered to the job site will meet or exceed the specifications. Any material not conforming shall be removed from the site at no additional cost to TVWD.

13. Disinfection and hydrostatic test results shall be observed and approved by TVWD.

14. Upon completion of installation of the water system, and before placing into service, all lines shall be flushed and disinfected in accordance with the Oregon health division guidelines and the requirements of the Oregon Department of Environmental Quality (DEQ). Disinfection shall conform with AWWA C651.

Two consecutive sets of bacteriological samples, taken at least 24 hours apart, shall be collected by TVWD representative from the new pipeline.

Applicable federal, state, and local regulations concerning discharge shall be followed.

16. There may be short sections of the pipeline that connect to the existing system that are difficult to chlorinate. The TVWD representative and the contractor shall identify these short sections of pipeline and an alternative method of disinfection employed. Chlorinate in accordance with requirements of specifications.
