When required by the Contract, this work shall consist of the Contractor providing all construction layout, surveying stakeout, and engineering necessary for the proper control of construction operations in accordance with this section and the "Manual on Construction Layout" unless otherwise approved by the Engineer. The "Manual on Construction Layout" may be obtained from the Construction Unit.
The Department will furnish and set horizontal centerline control and establish elevation benchmarks. The control points will be referenced by the Contractor and the references furnished to the Engineer. The Contractor shall verify the validity of the control points and benchmark elevations prior to beginning the construction layout. Any discrepancies noted shall be brought to the attention of the Engineer. Utilizing the benchmarks and horizontal control points established by the Department, the Contractor shall lay out the work and shall be responsible for all measurements that may be required for the execution of the construction in conformity with the plans and specifications or authorized revisions thereto.
The Department will establish the location of all proposed R/W monuments. The Contractor shall reference the location of all proposed R/W monuments that are within the construction limits. The Contractor shall reestablish this location upon completion of construction in this area and set the R/W monuments and guard stakes. At each location the Contractor shall install a right-of-way monument consisting of a right-of-way monument cap mounted on an 18" long #5 reinforcing bar and a fiberglass witness stake. The right-of-way monument cap shall be snugly secured to the top of the reinforcing bar with a hammer. The witness stake shall be located adjacent to the right-of-way monument and driven approximately 12" into the ground. Care shall be taken to prevent damage to the top of the monument cap or witness stake. The #5 reinforcing bar, monument cap, and witness stake will be provided by the Department.
The Contractor shall be responsible for the preservation of Department furnished centerline or baseline control and benchmarks. The Contractor shall establish and identify clearing limits. The Contractor shall provide all additional stakes including but not limited to centerline, Y-Line, connections, ramps, loops, slope stakes, right of way markers, fine grade stakes, construction benchmarks, and other reference marks or points that may be necessary to provide alignments and grades for construction of all roadway, structure, and miscellaneous items.
The Contractor shall perform any staking or restaking as deemed necessary by the Engineer to ensure all roadway, structure, and miscellaneous items are constructed in accordance with the established lines and grades. It shall be the responsibility of the Contractor to advise the Engineer of horizontal or vertical alignment revisions needed to establish smooth transitions to existing facilities. When requested by the Engineer, the Contractor shall check the accuracy of the stakeout and keep cost records to verify the cost of checking the stakeout. When the original stakeout is found to be correct, the Department shall reimburse the Contractor, if requested, for the verified actual cost of checking the stakeout. Payment for such additional surveying will be limited to an amount that does not exceed that which would have been made had the additional surveying been performed under the provisions of Article 1093. Where the original stakeout is found to be in error, the cost of checking and correcting the stakeout shall be at no cost to the Department.
The benchmarks furnished and established by the Department shall be preserved and protected by the Contractor. Any benchmarks conflicting with the construction of the project will be relocated by the Department upon request of the Contractor. Any temporary benchmarks which are needed for construction shall be established by the Contractor.
The Contractor shall stake the horizontal alignments shown on the plans or for borrow pits as deemed necessary by the Engineer for accurate measurement of quantities for payment. The staking of these horizontal alignments shall begin within 48 hours of the Engineer's notice to proceed. The contractor shall stake these alignments just before field cross-sections are taken by the Engineer for both original and final cross-sections. The Engineer may elect to take the cross-sections by either hand or aerial methods. In addition, the Contractor shall stake these alignments as deemed necessary by the Engineer for estimating quantities for partial payments. Cross-sections necessary for estimating these quantities will be taken by the Department. Stakeout of the survey line for final cross-sections shall be considered part of the work required prior to the final acceptance of the project. Upon the completion of the entire project with the exception of the survey line for final cross-sections and upon request by the Contractor, the project will be accepted, excluding the survey line, for maintenance by the Department. The Contractor shall set stakes to establish lines and grades for subgrade, base, curb, and related items at intervals along the line of work not greater than 50 feet. When the Engineer determines that horizontal or vertical alignments require the spacing of the stakes to be closer than 50 feet, the stakes shall be set accordingly. Grade stakes shall be set at intervals specified herein but at offsets determined by the Contractor to facilitate checking of all subgrade, base, curb, and pavement elevations including those in crossovers, intersections, and irregular shaped areas. The Contractor shall set slope stakes at all stations and half stations in accordance with the procedures established in the "Manual on Construction Layout".
Fine grade or other grade stakes required for the construction of the project shall be set as the work progresses. Fine grade hubs (blue tops) shall be set on both sides of each roadbed with distances and grades referenced to either the finished centerline or edge of pavement grade, as appropriate.
Structure construction stakes and other reference control marks shall be set at sufficiently frequent intervals to assure that all components of the structure are constructed in accordance with the lines and grades shown in the plans. The Contractor will be responsible for all structure alignment control, grade control, and all necessary calculations to establish and set these controls. The Engineer will furnish the Contractor the finished construction elevations for his use in determining the required construction elevations for bridges. The Contractor shall furnish a layout drawing for each structure after staking has been completed for review by the Engineer before the structure construction begins.
The Contractor shall make available to the Engineer all survey records made by his forces. The Engineer reserves the right to check, correct where necessary, or require any layout work to be revised. These records shall be available to the Engineer upon request for review during the project and submitted in total upon completion of the work. All inaccuracies in the construction stakeout shall be corrected by the Contractor prior to the Contractor being permitted to perform the affected work. Consideration will not be given for any extension of contract time or additional compensation due to delays, corrective work, or additional work that may result from construction layout, surveying, and engineering required by this specification except when such delays, corrective work, or additional work is through no fault of the Contractor.
At the beginning of the work, the Engineer will review the contractor's proposed method for setting up survey books to assure clarity and adequacy. The Contractor shall submit two (2) copies of all layout drawings for utility construction systems, drainage systems, and structures to the Engineer for his review or review and approval. The review or review and approval will be noted by the Engineer by adding an appropriate note to the drawings along with his signature. A copy of the drawings will be retained by the Engineer and a copy will be returned to the Contractor.
For roadway items, the Engineer will visually check the stakeout of survey lines, slope stakes, drainage and utility systems, fence stakes, right-of-way stakes, and fine grade stakes of all types. Periodic checks of each type of staking using the necessary surveying equipment will be performed.
For structure items a visual check will be made for the stakeout of box culverts and other minor structures for comparison with the Contractor's layout drawings. After the stakeout of each bridge and before work begins, the DOT survey crew shall make an independent verification of each reference point and each temporary benchmark. The Contractor shall submit his method for computing buildups over beams, screed grades, and overhang form elevations to the Engineer for review prior to staking out these items.
It is emphasized that the Department's checking of the Contractor's work in no way relieves the Contractor of responsibility for conformance with the plans and specifications. If the Engineer or inspector fails to point out from lack of discovery or for any other reason, it shall in no way prevent later rejection or corrections to the unsatisfactory work when discovered. The Contractor shall have no claim for losses suffered due to any necessary removals or repairs resulting from the unsatisfactory work.
The Contractor shall provide drainage location stakes, a sketch of the drainage system, and grades and elevations of the drainage system to the Engineer for review and approval prior to beginning work on a drainage system. In so doing, the Contractor will be responsible for investigating all existing and proposed utilities, all proposed utility construction, and existing drainage systems; locating all utilities, all proposed utility construction, all existing drainage systems; and considering their locations and elevations in the stakeout of the drainage systems.
For the utility work to be performed under the contract, the Contractor shall provide utility construction stakes; a sketch of the utility construction system; and elevations of the existing utilities, existing drainage system, and proposed drainage system to the Engineer for review and approval prior to beginning work on a utility construction system. The Contractor will be responsible for investigating all utilities, all proposed drainage systems, and all existing drainage systems and considering their locations and elevations in the stakeout of the utility construction.
When the Contractor is required to perform additional investigative surveying, which in his opinion could not have been reasonably anticipated and is not customary or inherent to the construction industry, he shall notify the Engineer in writing prior to beginning such additional surveying. When the Engineer determines that the investigative or supplemental surveying could not have been reasonably anticipated, the Department will reimburse the Contractor at the rate of $80.00 per hour for each and every hour the Contractor's survey crew is actively engaged in performing the additional investigative or supplemental surveying. The survey crew size shall be adequate to efficiently perform the work required and shall meet the approval of the Engineer. When the Engineer determines that the Contractor could have reasonably anticipated the need to perform the investigative survey, or such survey is customary or inherent to the construction industry, such survey shall be at no cost to the Department as such cost shall be considered to be part of the work required by the Department. Should the Contractor not agree with the decision of the Engineer, he shall strictly adhere to the provisions of Article 1048(B) of the Standard Specifications.
The Contractor shall furnish personnel, working under the supervision of a Registered Professional Engineer or Registered Land Surveyor, who are fully qualified and capable of establishing or reestablishing all line and grade points necessary to complete the work in accordance with the plan dimensions and to the tolerances established in the "Manual on Construction Layout" or as designated by the Engineer. The Contractor shall not engage the services of any person or persons in the employ of the Department of Transportation for the performance of any work covered by this item. All surveying equipment, stakes, and any material and equipment necessary to perform the work shall be furnished by the Contractor and shall be acceptable to the Engineer.
Acceptance or approval of all or part of the Contractor's layout by the Engineer shall not relieve the Contractor of his responsibility to secure proper lines, grades, and dimensions in the completed work, and he shall correct all errors caused by him at no cost to the Department.
