Our File 0773 December 9, 2008 NON-EXCLUSIVE PROFESSIONAL ENGINEERING AGREEMENT CONTINUING CONSULTING SERVICES ADDENDUM #1 TO "EXHIBIT 1" Background The Indian River County Utilities Department has decided to amend Work Authorization #11 which was approved by the Board of County Commissioners January 8, 2008. In preparation of the State of Florida Department of Transportation's (FDOT) plans to construct a four -lane to six - lane roadway expansion project along SR -60 between 66th Avenue and 82nd Avenue in Indian River County construction plans were developed to detail utility adjustments required in the proposed construction area. The County's intent was to provide the utility contractor a "one- step" construction process that would allow the required adjustments to be constructed without the need to return and make further adjustments after the completion of the FDOT roadway improvements. As a result, the adjustment planned for the existing 12" sewer force main at the southeast comer of SR -60 and 70 Avenue was designed to re-route the main under the existing 60" and proposed 84" storm pipe in the Indian River Farms Water Control District lateral canal. Although this design meets the intent of the "one-step" construction process, this design will result in a sewer force main being constructed extremely deep and in close proximity to existing and proposed traffic signal mast arms, signal switch gear, drainage pipes, and the Range Line Canal. While this is the best design following the "one-step" policy, it is not desirable since it will be difficult to construct and future maintenance would jeopardize the structural integrity of nearby roadway and drainage improvements. Although this design will require a "two-step" construction process to relocate the force main to its adjusted location, having the force main above rather than below the storm culvert justifies this modification to the construction concept. Scope of Services The additional services covered by this Amendment #1 to Work Authorization #11 will generally consist of the following • Prepare Construction Plans revisions and modifications to IRFWCD Permit to allow the force main to pass over the proposed new FDOT culvert at said location. • Prepare Construction Plans revisions and modification as requested by Indian River County Utilities to amend the design of the water main modifications on the south side of SR60, west of 74th Avenue.
