ATTACHMENT A Pan B SCOPE OF WORK INDIAN RIVER COUNTY NORTH COUNTY WATER TREATMENT PLANT ADMENDMENT NO. 2 - ADDITIONAL PERMITTING SERVICES BACKGROUND The North County Water Treatment Plant (NCWTP) is a permitted 3.53 million gallons per day (mgd) (3.0 mgd of permeate) facility serving northern Indian River County (IRC). The facility began construction in June 1996 and was placed into operation in July 1998. The existing plant draws water from three upper Floridan Aquifer wells. The facility currently utilizes two 1.5 mgd membrane treatment nanofiltration skids and incorporates a raw water blend rate of approximately 15 percent (0.53 mgd) to achieve the facility finished water capacity of 3.53 mgd. The facility layout was designed for future expansion at such time customer demand in the North County service area warranted. The original scope of services under Work Authorization No. 1 was to add three new 1.5 mgd nanofiltration skids during Phase II Expansion. The total plant rated capacity after this expansion would have been 7.5 mgd of permeate capacity. Based on IRC's request to provide additional standby capacity, this has been modified under Amendment No. 1 to include a total of six new 1.5 mgd nanofiltration skids. Based on the amended scope of services, the treatment plant will be designed to have permeate capacity of 12 mgd and a finished water capacity of 17.14 mgd (assuming 30 percent blend rate). Due to the site plan modifications required as part of the expansion, additional engineering services are required to permit the facilities. SCOPE OF SERVICES CDM shall provide the additional engineering services related to additional effort to procure the Florida Department of Environmental Protection Water Plant Construction Permits. Additional effort is also required to procure Indian River County's site plan major modification permit. The intent of this Amendment is to provide additional funding for the upper limit permitting services of Task 3 only. The level of effort required for permitting services is difficult to estimate since the responses are determined by the regulators. Therefore, if unforeseen tasks arise, CDM reserves the right to request additional funds to complete the effort. The following described engineering services are additional scope items not previously covered in the Phase II plant expansion Amendment I. These services will be addressed in the final plant permitting and covered under this amendment: Task 1.0 Preliminary Design (No Changes in this Amendment) Task 2.0 Preparation of Contract Documents CDM and Indian River County have been in the process of converting the 1996 version of the Engineers Joint Contract Documents Committee (EJCDC) procurement documents to the 2002 A-1 mh2405.aoc
