pump to the North Regional WWTP . Hydraulic modeling using Watercad will not be provided for the sewer system . An initial kick-off meeting to discuss available information and County standards to be used for this project will be conducted with IRC staff. Task 2 . Sanitary System Evaluation Consultant will review two different sewer system designs to be considered for Vero Lake Estates (VLE) — gravity-type and vacuum-type system . Consultant will review and present advantages and disadvantages of each type and provide recommendations for each based on these items . Some recent historical costs for these type systems in the geographic vicinity of Indian River County will be collected and provided . A cost/benefit evaluation will be provided under this task Task 3 . Prepare Opinion of Budget Costs The intent of this scope is to prepare a budget opinion of costs for the water/sewer system for each phase of the project . Estimated project costs were provided for water only in 1995 at an estimated cost of $ 1900/lot, however, given current market conditions, a more representative budget opinion of costs should be prepared . An opinion of overall probable construction costs with anticipated contingency' s will be prepared for each phase, including piping, valves , water services, sewer lateral connections , and hydrants . The opinions of costs will be budgetary in nature and more detailed costs can be prepared after detailed design is completed . Consultant will prepare a breakdown by phase and overall estimated costs as follows : 1 ) water only, 2) water & gravity, and 3 ) water & vacuum . The costs will include : contingency, survey, design, permitting, bidding, mobilization, & construction . Consultant will also include a preliminary schedule that outlines the beginning and completion of each phase . Task 4. Develop Survey Scope Consultant will develop a specific scope of services for the survey work to be completed . The same scope of services will be used for each of the five proposed phases . In order to tailor a scope of services for this project the Consultant will review the delineation of phases and the existing County utility survey specifications . The Consultant will participate in a site review with County staff to determine the level and limits of topographic information to collect and address any specific topographic requirements . Consensus on the utilization of rectified digital aerial photography will be sought. It is assumed that a digital base map of each phase will be developed based upon Indian River County GPS control points and tied to state plane coordinates .
