., .. <br />B. Preliminary Design shall consist of the following: <br />1. General Civil Design: <br />a. Horizontal and Vertical Alignment.- <br />b. Typical Sections. <br />c. Roadway Drainage Structures. <br />d. Relocation of Existing Roads and Ditches. <br />e. Right-of-Way Selection. .~ . ' . _° `. <br />f. Traffic Control. <br />g. Preliminary Cross-Sections for Preliminary Drainage and <br />Preliminary Earthwork. <br />h. Street Lighting. <br />2. Utilities Design and Coordination: <br />a. Preliminary Water Design. <br />b. Preliminary Sanitary Sever Design. <br />c. Preliminary Storm Water Drainage for Roadway. <br />d. Preliminary Contact xith Other Utilities. <br />3. Storm Water Management for Entire Area Contiguous xith Realigned Old <br />' Cleveland Road: <br />a. Consider Several Retention Areas (4 maximum). <br />h. Consider One Large Retention. Area. <br />4. Subsurface Investigation: <br />a. Soil Borings Recommendation. <br />C. Final Design shall consist of the following: <br />1. Upon approval of the Preliminary submittals, develop complete <br />designs and prepare final plans and specifications sufficient for <br />the CITY to receive competitive bids. <br />?. Complete water, sanitary sewer, storm sewer and retention basin <br />design. <br />3. Prepare. a detailed "Estimate of 6luantities" for roadway, water, <br />sanitary sewer, storm sewer and retention basin work. <br />4. Prepare an "Engineer's Estimate" of construction costs for each <br />construction contract based upon the approved contract drawings, <br />using estimated quantities and current unit prices. <br />S. Participate in field and office reviews of plans and documents as <br />required during the design development. <br />6. Prepare a drainage study of the approximately 438 acres which drain <br />toward this project. It is understood that this 438-acre site has <br />keen divided into four (4) separate drainage areas in earlier <br />"Airport 2010 Project" reports, and that it is the CITY's intention. <br />• that these areas will have no more than one (1) retention basin. If <br />two or. more areas can be combined into one retention area, this will <br />be done. <br />Page 5 <br />
