210.3(d) 210.4(b) minimum, the QC Plan must demonstrate that the grading control equipment meets the performance requirements within acceptable tolerances. At a minimum, set construction stakes at right angles to the centerline on tangents and radial offsets on curves at 500 -foot intervals the entire length of mainline. In addition, set a minimum of two constructions stakes on each ramp, on each intersecting roadway, and on projects less than 1000 feet in length. Tabulate offsets and elevations of all stakes using Form D-413 (Grade Sheet) located in Publication 122M, Appendix C, and provide to the Representative. Rough grade and fine grade stakes will be accompanied by a guard stake for easy identification. Provide control points and conventional grade stakes at critical locations such as, PC’s, PT’s, superelevation points, and other critical points required for the construction of drainage and roadway structures. Provide other points of reference necessary to establish quality control or for verification of accuracy by the Department. Provide the same Survey Grade GPS network to the Department as that used during construction. The Department will review the network and monitor the project. Check and recalibrate, if necessary, the GPS or laser machine control system at the start of each workday . Test the finished surface at all hinge points and/or centerline, edge of lane, and edge of shoulders on the cross -section at all critical locations and as established in the QC Plan. Correct surface irregularities exceeding 1/2 inch by loosening the surface and removing or adding material as required. Compact the corrected area and surrounding surface by rolling. Recheck the corrected subgrade area for grade and shape. Upon successful quality control testing, notify the Representative the subgrade is ready for acceptance. At a minimum, the Representative will test the finished surface at all hinge points and/or centerline, edge of lane, and edge of shoulders on the cross -section at a random locations every 500 feet for acceptance. Correct all areas exceeding 1/2 inch. If more than 10% of all acceptance tests are determined to exceed 1/2 inch in any phase of the project, the Representative may require stakes and stringline be established as specified in Section 210.3 (c). Provide all electronic data files used for the construction of the fine grade of the roadway to the Representative.
