Design <br /> Service Provider's design of the modified portal project shall include two draft phases and associated <br /> deliverables along with a final, PE-stamped and signed deliverable suitable for bidding the construction <br /> contract. <br /> The modified portal structure shall connect to the existing tunnel and to the existing steel pipe spool <br /> that leads to the pipeline that extends to the diversion dam on the Sultan River. It is understood that <br /> this steel pipe spool and steel pipe section connect to reinforced concrete pipe somewhere toward the <br /> diversion dam. <br /> The modified portal structure shall be comprised of the following key features: <br /> • Removal of a portion of the existing concrete tunnel portal structure (approximately the furthest 20 <br /> linear feet to the east). This includes the portion of the tunnel portal that connects to the pipeline <br /> that extends to the diversion dam as well as the vertical and horizontal access. It includes exposing <br /> and leaving in place the existing steel pipe spool that serves as an increaser that connects from the <br /> existing portal structure to the 72-inch pipeline that extends to the diversion dam. <br /> • A new steel pipe placed inside the remaining existing tunnel portal structure that extends <br /> approximately 10 to 20 feet inside the tunnel and is a total of approximately 70 to 80 feet in length. <br /> Grout the annular space between the steel pipe and the existing tunnel portal structure. <br /> • A new cast-in-place reinforced concrete structure that connects the new steel tunnel liner pipe and <br /> the existing steel increaser spool that connects to the pipe that extends to the diversion dam. A <br /> vent will be incorporated into the new cast-in-place concrete structure. Horizontal access similar to <br /> the existing horizontal access will be incorporated at approximately the same location. <br /> The design is anticipated to include technical specifications for steel pipe,cement grout,cast-in-place <br /> concrete, reinforcing steel,coatings systems,and other ancillary elements. The project drawings shall <br /> include all title, index,general,demolition, structural,site civil, and related details to enable bidding the <br /> project. <br /> Additionally,Service Provider shall complete all applicable Division 0 and Division 1 specifications for the <br /> project, including advertisement, bidding, bonding,Agreement, and general conditions. Service <br /> Provider shall use City's standard Division 0 specifications and Service Provider's standard Division 1 <br /> specifications. <br /> The draft and final design phases are presented in the subtask descriptions below. Service Provider shall <br /> furnish review comment logs at each draft design stage to City for use in summarizing, documenting, <br /> and transmitting City review comments. <br /> 2.1 30-Percent <br /> Service Provider shall prepare a 30-percent complete submittal of the design. During this phase of <br /> design,the site civil elements of the project will be advanced to characterize impacts during <br /> construction and present the post-construction condition. The configuration and dimensions of the new <br /> portal structure will be developed as well as site civil plan and grading(including vehicle access to the <br /> site). Title and other general drawing sheets will be developed. No specifications will be developed for <br /> the 30 percent design. No connection, structural, or site civil details will be developed for this submittal. <br /> 3 <br />
