The final report that will be submitted to the SEO will include the District's comments along with the design <br /> team's internal QA/QC comments. <br /> Deliverables: Draft and Final Basis of Design Reports <br /> Task 7-Spillway Rehabilitation Design <br /> Drawings and Technical Specifications will be prepared for the spillway rehabilitation portion of the project. <br /> This is anticipated to include spillway entrance training wall additions, raising the training walls along the <br /> right and left sides of the spillway chute, replacement or rehabilitation of failed spillway slabs, and armoring <br /> in the area of the plunge pool. <br /> Drawings will be prepared in AutoCAD 2011, or later version, using D&A's company standards. Drawings <br /> will be prepared in 22-inch by 34-inch format with true half-sizes at 11-inch by 17-inch. Technical <br /> Specifications will follow the 17 Division CSI format. D&A's standard technical specifications will be <br /> followed and the District's standard front-end contract documents will be used. <br /> Progress submittals will be made at the 30 percent, 90 percent, and 100 percent levels of completion. <br /> Progress submittals will be made electronically and at half-size hard copy. At the 100 percent level of <br /> completion, documents will be full size signed and sealed in accordance with Colorado law and submitted to <br /> the SEO for review and approval. It should be noted that the progress submittals for other portions of the <br /> work will be combined in a single drawing and specification set. <br /> Deliverables: 30 percent, 90 percent, and 100 percent Drawings and Technical Specifications <br /> Task 8-Clay Blanket Design <br /> Drawings and Technical Specifications will be developed for the upstream clay blanket permeability barrier. <br /> Drawing and specification format and progress submittals will be the same as described under Task 7. The <br /> design of the clay blanket is expected to include plans, cross-sections, and details that describe the site <br /> preparation required in advance of blanket installation; location of the clay blanket; and thickness, material <br /> type, and gradation for each zone. This task will also cover the design and installation of additional toe <br /> drains on the downstream left abutment of the dam. <br /> Deliverables: 30 percent, 90 percent, and 100 percent Drawings and Technical Specifications <br /> Task 9-Bypass Tunnel Design <br /> Drawings and Technical Specifications will be developed for the bypass tunnel option. Drawing and <br /> specification format and progress submittals will be the same as described under Task 7. The design of the <br /> bypass tunnel will involve a 14-foot finished diameter tunnel that bypasses the existing sluice gate structure <br /> in the outlet tunnel and will be included in the contract documents as Option 2. Work in this task will also <br /> include the design of Option 1 which involves the demolition of the existing sluice gate structure with no <br /> bypass tunnel constructed. The Option I design will include demolition drawings,rock anchoring portions <br /> of the old concrete,and installation of a new reinforced concrete or shotcrete crown liner to create a <br /> hydraulically smooth crown of the tunnel where the gate structure was removed. The design of the bypass <br /> tunnel will include rock bolt support design for the tunnel intersections and thin shotcrete liner for <br /> pressurized tunnel sections. <br /> Deliverables: 30 percent, 90 percent, and 100 percent Drawings and Technical Specifications <br /> - 6 - <br />
