HomeMy WebLinkAbout2007-224 �? -17 d? r LZ� AMENDMENT 2 �.OJ7- LL FINAL DESIGN AND PLANS PREPARATION FOR CR 510 from CR 512 to east of 75`° Court This is an amendment to the existing Final Design and Plans Preparation services agreement (AGREEMENT), dated November 17, 2005 , by and between INDIAN RIVER COUNTY , hereinafter referred to as the COUNTY , and STANLEY CONSULTANTS, INC., hereinafter referred to as the ENGINEER . This amendment addresses changes in "Section I — Project limits and Description , Section III — Scope of Services, Section IV — Time for Completion, and Section V - Compensation " of the AGREEMENT. Amendment Description SECTION I - PROJECT LIMITS AND DESCRIPTION is being modified to incorporate the following engineering services which are required: a) Locate existing subsurface utilities at potential conflict points between proposed features (storm sewer pipe/inlets and signal mast arms) with existing potable water and sanitary sewer force main. Locates for other utilities including Bell South, FPL and Comcast are not included in this amendment. b) Design the relocation of Lateral D Canal required to accommodate the new CR510 box culvert at 89" Street and to accommodate the new bridge structure over Lateral D Canal (Note: Said new bridge structure design and associated bank and shore design shall be designed by others and not included in this amendment). The limits of Lateral D Canal realignment will begin near Baseline Construction Station 60+00 and extend south for 1400 lineal feet. c) Permitting effort required for the relocation of Lateral D Canal . Starting near Baseline Construction Station 60+00 and extending south for 1400 lineal feet. d) Survey and provide sketch and description for property take due to proposed Lateral D Canal realignment. Assist Geotechnical Engineer with Baseline Survey location . e) Geotechnical investigation along realignment of Lateral D Canal and provide slope stability analysis and recommendations for proposed slope stability measures along Lateral D Canal for length of realignment, approximately 1400 lineal feet. f) Prepare a Bridge Report for CR 510 over the Slough, Sta. 175 +40, to determine three structure alternatives which will accommodate wildlife. g) Design the bridge structure at CR 510 over Slough rather than original box culvert. SECTION II — not applicable CR 510 Amendment 2 Page l of 6 6/25/2007 SECTION III - SCOPE OF SERVICES is being modified to incorporate the following: The ENGINEER agrees to perform professional roadway design and related services in connection with the project as required and set forth in the following: A . Utility Subsurface Locates (InfraMan Corp) Horizontal and vertical location of existing 16" water main and 12" force main utilities at conflicts with the proposed storm sewer pipes, storm sewer structures and proposed signalization mast arms. Design services will include the following tasks : 1 . Perform a total of 107 subsurface utility locations using air/vacuum method at the conflicts with the proposed storm sewer facilities (74 potential conflicts) and proposed signalization mast arms (estimated 33 potential conflicts: 11 mast arms and 3 holes per location) with existing subsurface utilities. The 74 locates include 30 locates for the existing 12" force main and 44 locates for the existing 16" water main. 2. Survey the horizontal and vertical location at each subsurface utility location for conflicts with the proposed storm sewer facilities and the proposed signalization mast arms. B. Drainage Design — Lateral D Canal Realignment (Stanley Consultants) Design the relocation of Lateral D Canal for approximately 1400 lineal feet using the proposed alignment and cross section of Lateral D Canal approved during the June 15, 2006 Board meeting with Sebastian River Water Control District. This Amendment does not include analyzing or designing other Canal alignment or cross section alternatives. Additional design services will include the following tasks: 1 . Design the horizontal and vertical alignment of Lateral D Canal from Station 60+00 to Station 74+00 . 2 . Create four plan/profile sheets and show plan design of Lateral D Canal at 1 "=40 ' scale. 3 . Create eight cross section sheets and show cross section design of Lateral D Canal including earthwork quantities. A vertical match line will be used to separate the CR510 alignment and the Lateral C Canal alignment. 4. Revise the three proposed pipe laterals that directly discharge to Lateral D Canal from Sebastian River Water Control District right-of-way. 5 . Design erosion protection measures (bank stabilization) on the downstream end of the 89`1 Street Canal box culvert at the confluence of Lateral D Canal. The limits of the bank stabilization will include the east side and west sides of Lateral D Canal, as well as the canal bottom. The north-south limits will extend north to Station 68+50 and south to station 70+00, for a total of 150 ' . This does not include the bank stabilization for a future 89'h Street bridge (to be designed by others) that leads to Blue Water Bay and Sebastian Lakeview Estates PUD 's. CR 510 Amendment 2 Page 2 of 6 6/25/2007 C. Permitting — Lateral D Canal Realignment (Stanley Consultants) Include the Lateral D Canal realignment work effort in the Environmental Resources Permit to St. Johns River Water Management District. Additional services will include the following tasks: I . Update the wetland report and coordinate further with St. Johns River Water Management District. 2. Determine impacts, if any, to endangered species. Coordinate further with U. S. Fish and Wildlife Service. 3 . Perform one site review. D. Survey - Parcel right-of-wav needs associated with Lateral D Canal Realignment Area (Burdette and Associates) Provide design survey to encompass an area between the existing Sebestian River Water Control District Canal D right-of-way line and the proposed SRWCD right-of-way line due to canal re-alignment. The design services will include the following tasks: 1 . Provide design survey to encompass an area between the existing SRWCD right-of-way line and 25 feet beyond the following points describing the proposed SRWCD right-of-way line, referenced to the Baseline Survey: Station 63 +96.40, 184. 71 LT; Station 68+89 . 51 , 223 .01 LT; and Station 69+84.68, 226 .97 LT. 2.
