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.
