Waterline Design. This task includes design and preparation of documents for the 30%, 60%, 90% and final submittals. This project will replace or relocate water mains, services, fire hydrants and associated appurtenances, as required for the roadway improvements. Assumptions: Approximately 1000-feet of new water main in Xxxx Road. Approximately 800-feet of new water main in Xxxxxxx Boulevard. Connection details to the existing water mains at existing junctions and the project limits. Connections to existing water services and meter relocations if needed. All design assumed to be within the proposed public right of way. Does not include relocation of backflow preventers on private property. The City will specify new pipeline diameters. Hydraulic analysis is not included. Existing utilities to be abandoned in place where appropriate.
Waterline Design. It is assumed there will be ~1,000 feet of waterline replacement along 119th Street. It is assumed all waterline requiring replacement is owned by Olathe Water.
Waterline Design. A1. This proposal assumes the design of 400 linear feet of 6" waterline. Design shall include one (1) Plan and Profile sheet for the waterline design.
Waterline Design. The CONSULTANT shall prepare PS&E for both the temporary and permanent waterline relocation for the road bridge alternative. CONSULTANT Services • Attend kickoff meeting with Thurston County PUD (PUD) and COUNTY Staff. • Prepare 60%, 90%, and Final PS&E waterline drawings for COUNTY and Thurston County PUD (PUD) review. • Incorporate Waterline design into Task 4 deliverables. • Respond to consolidated review comments prepared by the COUNTY and PUD for the 60% and 90% and Final submittals (See Task 4). • Attend 60% and 90% and Final review meetings with the COUNTY and PUD to discuss review comments (See Task 4). COUNTY Responsibilities • Coordinate directly with PUD for meetings and review comments. • Attend kickoff meeting with HDR and PUD. • Attend 60% and 90% review meeting with HDR and the PUD as part of Task 4. • Prepare consolidated comments with the PUD as part of Task 4. • Track Task 2.3 budget internally for reimbursement from the PUD. Assumptions • PUD will attend kickoff meeting and both 60% and 90% design review meetings with the COUNTY and HDR. Kickoff Meeting will be held virtually and attended by two CONSULTANT staff members. The Kickoff meeting will be two hours in duration. The 60% and 90% review meetings are part of Task 4. • PUD will submit consolidated comments directly to the COUNTY. • The temporary pipe will not be directionally bored. • The temporary pipe will be 4-inches to 6-inches in diameter. If hydraulic modeling is required it will be done by the PUD. The PUD will provide the system pressures. • The temporary/permanent piping will have isolation valves on both sides of the bridge along with blow off and air release valve(s) as necessary. • The temporary pipe will be HDPE. • There is asbestos concrete pipe removal and disposal for the existing watermain piping. • The permanent pipe will be secured to the bottom of the road bridge. • The permanent pipe affixed to the bridge will be Ductile Iron and require an insulated jacket for freeze protection. • No cathodic protection is required. • All other permanent pipe shall be buried within a trench and will be C900 PVC. • A OPCC will be prepared based upon the AACE International 18R-97 cost classification for both the temporary and permanent piping and associated appurtenances. • Drawings will be created in AutoCAD format using COUNTY standards. • The 60%, 90% and Final contract plans are based upon the following five sheets:
Waterline Design a. Provide 30%, 60%, 90%, and Final Design submittals as with the Roadway & Drainage Design for upgrading replacement of all water lines along the project limits.
Waterline Design. This task includes design and preparation of documents for the 30%, 60%, 90% and final submittals for Phase 1. The project will replace or relocate water mains, services, fire hydrants and associated appurtenances, as required for the roadway improvements. Phase 1 work includes: • Installation of a new pressure-reducing valve (PRV) in the vicinity of Xxxxxx Xxxx on Bear Creek Road between zones 4B and 5 (V-2 in iWSMP). • 12-inch and 8-inch new connections on Bear Creek Rd between Cessna Dr and Janalee Pl (P-26 in iWSMP).
