density of layout will be at the discretion of the Contractor, but not in conflict with the Engineer's ability to verify accuracy of the construction engineering. 3. All construction engineering shall be performed by the Contractor, with all required materials provided by the Contractor at his expense. Construction engineering shall include re-establishing the survey points and survey centerlines; referencing the necessary control points; running a level circuit to confirm plan elevations and to establish elevations on new benchmark tablets; setting stakes for right-of-way, culverts, slopes, subsurface drains, paving, subgrade, curb, headwalls, structures and all other stakes required for control lines and grades; and setting vertical control elevations for such. This information shall be used to verify that the planned alignment and elevations will match existing conditions. Required alignments and elevations will be shown on the plans. Prior to incorporating established grades, the Contractor will be required to determine that all other planned elevations are in accordance with field conditions. The profiling of existing pavements beyond tie-in points for proper ride, profiling of existing ditches for proper flow, and visual observations that driveways or sidewalks may be constructed satisfactorily will be required. All discrepancies shall be brought to the immediate attention of the Engineer. All changes in the design due to major discrepancies brought to the attention of the Engineer will be provided by the Owner.
