Except for the survey control data to be furnished 2 <br />by the Contracting Agency, calculations, surveying, and measuring required for setting 3 <br />and maintaining the necessary lines and grades shall be the Contractor's responsibility. 4 <br /> 5 <br />The Contractor shall inform the Engineer when monuments are discovered that were not 6 <br />identified in the Plans and construction activity may disturb or damage the monuments. 7 <br />All monuments noted on the plans “DO NOT DISTURB” shall be protected throughout the 8 <br />length of the project or be replaced at the Contractors expense. 9 <br /> 10 <br />Detailed survey records shall be maintained, including a description of the work 11 <br />performed on each shift, the methods utilized, and the control points used. The record 12 <br />shall be adequate to allow the survey to be reproduced. A copy of each day's record shall 13 <br />be provided to the Engineer within three working days after the end of the shift. 14 <br /> 15 <br />The meaning of words and terms used in this provision shall be as listed in "Definitions of 16 <br />Surveying and Associated Terms" current edition, published by the American Congress 17 <br />on Surveying and Mapping and the American Society of Civil Engineers. 18 <br /> 19 <br />The survey work shall include but not be limited to the following: 20 <br /> 21 <br />1. Verify the primary horizontal and vertical control furnished by the Contracting 22 <br />Agency, and expand into secondary control by adding stakes and hubs as well 23 <br />as additional survey control needed for the project. Provide descriptions of 24 <br />secondary control to the Contracting Agency. The description shall include 25 <br />coordinates and elevations of all secondary control points. 26 <br /> 27 <br />2. Establish, the centerlines of all alignments, by placing hubs, stakes, or marks on 28 <br />centerline or on offsets to centerline at all curve points (PCs, PTs, and PIs) and 29 <br />at points on the alignments spaced no further than 50 feet. 30 <br /> 31 <br />3. Establish clearing limits, placing stakes at all angle points and at intermediate 32 <br />points not more than 50 feet apart. The clearing and grubbing limits shall be 5 33 <br />feet beyond the toe of a fill and 10 feet beyond the top of a cut unless otherwise 34 <br />shown in the Plans. 35 <br /> 36 <br />4. Establish grading limits, placing slope stakes at centerline increments not more 37 <br />than 50 feet apart. Establish offset reference to all slope stakes. If Global 38 <br />Positioning Satellite (GPS) Machine Controls are used to provide grade control, 39 <br />then slope stakes may be omitted at the discretion of the Contractor 40 <br /> 41 <br />5. Establish the horizontal and vertical location of all drainage features, placing 42 <br />offset stakes to all drainage structures and to pipes at a horizontal interval not 43 <br />greater than 25 feet. 44 <br /> 45 <br />6. Establish roadbed and surfacing elevations by placing stakes at the top of 46 <br />subgrade and at the top of each course of surfacing. Subgrade and surfacing 47 <br />stakes shall be set at horizontal intervals not greater than 50 feet in tangent 48 <br />sections, 25 feet in curve sections with a radius less than 300 feet, and at 10-49 <br />foot intervals in intersection radii with a radius less than 10 feet. Transversely, 50 <br />stakes shall be placed at all locations where the roadway slope changes and at 51 <br />additional points such that the transverse spacing of stakes is not more than 12 52
