No guarantee is made the data systems used by the Department will be directly compatible with the systems the Contractor uses. The Department will develop and make available electronic data to the Contractor for review as part of the contract bid documents as specified in Section 102.06(e) . Ensure the electronic data will function in the Contractor’s machine control grading system before the bid.
which includes a contract pay item for construction surveying and if AMG is utilized by the C ontractor. Survey control includes all statewide or local , primary and secondary , and horizontal and vertical controls used for the geospatial positioning of work items. Upon completion of initial survey reconnaissance control verification and 5 working days before the scheduled beginning of primary field operations, submit the Contractor Survey Control Report FormS -686 AMG -1 signed and sealed by a Professional Land Surveyor registered in the State. Include the following required control information (tabular form is acceptable) as part of the Contractor Survey Control Report FormS -686-AMG -1:
• All contract control shown in the contract documents or in the Contractor Survey Control Report
• Submit all contract control points and benchmarks:
ͦ Indicate which control points and benchmarks were recovered in the field and their condition . ͦ Contract coordinate or elevation ͦ Field determined coordinate or elevation ͦ Contractor adjusted coordinate or elevation, if necessary ͦ Control points and benchmarks intended to be used for construction purposes ͦ Site Calibration method utilized and a report of the following:
- A scaled CADD drawing, sketch , or diagram showing project location and control points used to determine the site calibration. The project location must be fully contained in the site calibration control points. - A detailed software report of the site calibration - Report all survey control points within tolerance used in the site calibration. Horizontal allowable error ± 0.04 feet, Vertical allowable error ± 0.08 feet - Report checks of all recovered original survey control points not used in the site calibration .
• Adjustment method used to balance or adjust the control (e.g. Compass Rule for Baseline, Calibration Report for GNSS, etc.). Attach a copy of the localization or site calibration necessary for Survey Grade GNSS Inspection and Automated Machine Guidance alo ng with a ll other miscellaneous adjustments.
