Contractor Staking Quality Control Plan (CSQC)

The contractor quality control plan is an important communication tool that identifies key contacts, quality control procedures, documentation methods, equipment certification, staking tolerances, and field equipment check procedures.

CONTRACTOR STAKING QUALITY CONTROL PLAN

CONTRACTOR STAKING QUALITY CONTROL PLAN

^====Quality Control Staff====

• The licensed professional surveyor named in the quality control plan should be the individual responsible for providing professional oversight of the staking activities. This person does not need to serve as the plan manager or site contact, but may do so if appropriate.

Equipment Calibration

• Copies of equipment certification for levels, transits, lasers, and total stations should be provided to the Engineer. Equipment should be calibrated at a minimum on an annual basis and as needed throughout the project. Field checks should be performed and documented.

Certification

Provide equipment calibration certification documentation for levels, transits, lasers, and total stations. Calibration certifications must be completed by a third-party verifying that equipment meets the accuracy requirements as specified by the manufacturer.

Onsite Field Equipment Checks

Check and test equipment prior to use and per manufacturer’s specifications. Perform additional checks if equipment accuracy becomes questionable due to impacts, environmental conditions, or observed inconsistencies.

1. Method of Field Verification Perform field checks in accordance with the Design Survey Manual and the Survey Standards of Practice procedures and manufacturer-recommended methods applicable for the equipment used. Document all verification activities, including the method, readings, and adjustments made during the project and provide to the Engineer.
2. Documentation Submit field verification records to the Engineer. Records must include:
   1. Date of field verification
   2. Equipment type, model, and serial number
   3. Verification method used
   4. Recorded readings and any adjustments
   5. Confirmation of compliance with tolerance limits

Non-Compliant Equipment

Remove equipment immediately from service if it is found to be out of tolerance during checks. Recalibrate and recertify the equipment before returning to service. Notify the Engineer and provide recalibration and recertification documentation.
