<br />Copyright 2002 AIA <br /> <br />MASTERSPEC <br /> <br />11/02 <br /> <br />electrical work. Transfer survey markings and elevations for use with control lines and levels. <br />Level foundations and piers from two or more locations. <br /> <br />E. <br /> <br />Record Log: Maintain a log of layout control work. Record deviations from required lines and <br />levels. Include beginning and ending dates and times of surveys, weather conditions, name and <br />duty of each survey patty member, and types of instruments and tapes used. Make the log <br />available for reference by Architect. <br /> <br />3.4 <br /> <br />FIELD ENGINEERING <br /> <br />A. <br /> <br />Identification: Owner will identify existing benchmarks, control points, and property corners. <br /> <br />B. <br /> <br />Reference Points: Locate existing permanent benchmarks, control points, and similar reference <br />points before beginning the Work. Preserve and protect permanent benchmarks and control <br />points during construction operations. <br /> <br />1. Do not change or relocate existing benchmarks or control points without prior written <br />approval of Cons1ruction Manager. Report lost or destroyed permanent benchmarks or <br />control points promptly. Report the need to relocate permanent benchmarks or control <br />points to and Construction Manager before proceeding. <br />2. Replace lost or destroyed permanent benchmarks and control points promptly. Base <br />replacements on the original survey control points. <br /> <br />C. Benchmarks: Establish :md maintain a minimum of two permanent benchmarks on Project site, <br />referenced to data established by survey control points. Comply with authorities having <br />jurisdiction for type and size of benchmark. <br /> <br />1. Record benchmark locations, with horizontal and vertical data, on Project Record <br />Documents. <br />2. Where the actual location or elevation of layout points cannot be marked, provide <br />temporary reference points sufficient to locate the Work. <br />3. Remove tempor~il'Y reference points when no longer needed. Restore marked <br />construction to its original condition. <br /> <br />D. Certified Survey: On completion of foundation walls, major site improvements, and other work <br />requiring field-engineering services, prepare a certified survey showing dimensions, locations, <br />angles, and elevations of construction and sitework. <br /> <br />E. Final Property Survey: Prepare a fmal property survey showing significant features (real <br />property) for Project. Include on the survey a certification, signed by land surveyor that <br />principal metes, bounds" lines, and levels of Project are accurately positioned as shown on the <br />survey. <br /> <br />1. Show boundary lines, monuments, streets, site improvements and utilities, eXlstmg <br />improvements and significant vegetation, adjoining properties, acreage, grade contours, <br />and the distance and bearing from a site corner to a legal point. <br />2. Recording: At Substantial Completion, have the final property survey recorded by or <br />with authorities having jurisdiction as the official "property survey." <br /> <br />EXECUTION REQUIREMENTS <br /> <br />01700-4 <br />
