740Construction Layout

740.01 DESCRIPTION. This section sets forth requirements for all

construction layouts. Establish lines and grades, take all cross-sections, and stake out the construction work in accordance with these specifications, plan details, and as directed. Construction layout also includes, but is not limited to, the layout of pavement striping and raised pavement markers, setting of line and grade for construction of superelevated curves or other applicable work items, and assisting in the coordination of utility relocation activities to ensure that the placement of relocated facilities will not conflict with required construction.

740.02 CONSTRUCTION REQUIREMENTS. Establish all lines and

grades and stake out all project work, including sufficient vertical and horizontal control points for utility relocations for use by the Department and others. The project survey control and horizontal alignment are based on the Louisiana State Plane Coordinate System. The construction plans and/or right-of-way map depicts the coordinates and datum of sufficient survey control points to establish or re-establish horizontal control throughout the length of the project. Employ such methods as approved by the project engineer for the location of the project alignment and other necessary survey control points in accordance with currently acceptable surveying standards and practices. When required, the Department will also provide one bench mark on or near the project for vertical control. Verify the values of any intermediate bench marks shown on the plans, by checking against the bench mark established by the Department for vertical control. Employ qualified engineering and surveying personnel experienced in layout and construction of highways and bridges to correctly establish and keep complete and comprehensive records (field books or approved electronic files) of all lines and grades necessary from initial layout to final acceptance. Provide sufficient qualified staff, of at least one employee, on site during utility relocation periods. Provide any necessary survey work to ensure there are no utility conflicts with required construction. Provide daily documentation of utility relocation activities for incorporation into the project diaries. The contractor shall be liable for the accuracy of the initial layout and all subsequent alignment and elevations and shall, at no additional pay, rebuild, repair or make good any portion of the work found to be incorrectly positioned either horizontally or vertically at any time before final acceptance. Notify the engineer immediately of any apparent errors in the plans. Compute and provide template grades to the engineer. In order to obtain pipe order lengths, provide the appropriate grades to the engineer two weeks in advance of the work. Numbered notebooks for recording of all lines and grades will be provided by the Department and shall be properly indexed and cross referenced by the contractor before return to the engineer for submittal with the final estimate. Computer generated printouts will be allowed when approved. Set stationing for overlay projects using an approved measuring device that is accurate to 0.1 percent. Place stakes every 100 linear feet and maintain throughout construction. For pavement preservation type projects, the contractor will be responsible for recording the location of all existing pavement markings and laying out the required final markings subject to the approval of the Project Engineer. Perform the layout of striping, raised pavement markers, and signs by methods approved by the engineer prior to placement.

740.03 MEASUREMENT. Measurements for determination of pay

quantities will be made by the Department. Construction layout and utility oversight and coordination will be measured per lump sum, which will include all labor, materials, tools, equipment, and incidentals required to complete the work. No changes in the lump sum contract price will be made for minor additions or deletions to the scope of work.

740.04 PAYMENT. Payment for construction layout, and utility oversight

and coordination will be made at the contract lump sum price in accordance with Table 740-1 and Table 740-2, respectively.
