<br />will advise the City of data and information the Engineer needs to perform its services, and <br />the Engineer will meet with City representatives at mutually convenient times to assemble <br />this data and information. <br /> <br />1.2 TASK 1 - INTERIM AND FINAL PLANS <br /> <br />For all ten crossing locations the Engineer will: <br /> <br />Survey <br /> <br />1.2.1 Provide land surveying for design and layout CADD work, and provide for field <br />surveys and perform related office computations and drafting for the purpose of collecting <br />information required for design. <br /> <br />1.2.2 Perform survey work to include horizontal and vertical control adequately <br />documented for the final plans. Horizontal control will be based on the Texas State Plane <br />Grid Coordinate System (NAD83). The vertical control will be based on the U.S. <br />Geological Survey (USGS) datum and Benchmarks will be established not more than 1000 <br />feet apart at an accuracy of 0.01 feet. <br /> <br />1.2.3 Tie visible topographic features to the Project center lines and include existing <br />property or lease lines, property or lease corners, utilities and appurtenances, roadways, <br />structures, railroad structures, trees over six inches in diameter, and other topographic <br />features within the limits of construction and 25 feet beyond. <br /> <br />Geotechnical <br /> <br />1.2.4 Explore the subsurface materials and conditions at the sites by drilling ten borings <br />to a maximum depth of 15 feet, one boring at each of the ten crossings. <br /> <br />1.2.5 Conduct subsurface water observations ;n each boring before drilling fluid is used <br />to advance the borings. <br /> <br />1.2.6 Determine existing conditions, strength and index properties, and characteristics of <br />the subsurface materials by appropriate laboratory tests and present the results of the <br />analyses in three copies of a written engineering report. The Engineer will use the <br />information obtained to establish the excavatability and hardness of the subsurface <br />materials. <br /> <br />Preliminary Engineering <br /> <br />1.2.7 Review the existing records of the City concerning the existing water lines and <br />review existing plans, maps records, data and other available information as necessary. <br /> <br />1.2.8 Conduct one site visit to all locations, to perform site analysis and to determine site <br /> <br />2 <br />
