I I I f) Preliminary Design drawings - Using the preliminary geotechnical engineering report prepared by Fugro Consultants, produce drawings showing a demolition plan of the right bank and abutment areas. REP will provide drawings showing proposed in-stream improvements. KBR/Greenway are responsible for providing drawings showing each of their proposed construction areas. The City will combine all drawings into a draft Preliminary Engineering Report (PER) by February 20, and a final PER by February 27th. The City will provide both the draft and final PER drawings to state and federal permitting agencies as required. The Engineer will provide an interim right bank grading plan including any structural members necessary for stabilizing the existing retaining wall and future improvements as required. The Engineer anticipates preparing the following sheets: 1) Existing Base Map; 2) Demolition Plan - for dam, right bank retaining wall, and park pavilion; 3) Erosion Control Map and Details 4) Interim Grading Plan and Cross Sections - showing right bank grading to stabilize area after removal of retaining walls and pavilion and to provide access to the in-stream contractor. Final grading and amenities will not be included at this time, 4) Hydraulic Plan and Profile of San Marcos River - showing hydraulic cross-section location with 100-year floodplain and stream profile showing channel invert, cross-section location and flood profile levels; 5) Proposed Plan View Map showing improvements with construction limit line, staging areas for equipment and material storage. The Engineer and REP will work with general contractor(s) to produce this drawing. g) Proposed Hydrologic and Hydraulic Model- prepare hydraulic model to address the channel condition of no rise allowed for the 100-year flood event in the San Marcos River including a tabulation of existing and proposed project condition water surface elevations. Develop 10, 50, 100 and 500-year flood profiles. h) Probable Cost Estimate - A probable cost estimate for the demolition and interim grading plan will be provided. 1.2.6 Provide deliverables in the form of a preliminary engineering report which documents all the above items in a comprehensive report with appendices for geo-tech report and hydraulic models to be incorporated in the City's PER. The PER will be compatible with the Preliminary Design Drawings. 1.3 TASK 2 - FINAL DESIGN The Engineer will: 1.3.1 After review by the City and Contractor of the Preliminary Design Drawings revise and submit ten (10) sets of sealed construction drawings and technical specifications.. The City will Halff Prof Services 4
