Description https://safety.fhwa.dot.gov/roadway_dept/countermeasures/reduce_crash_severity/listing.cfm?code=workzone https://safety.fhwa.dot.gov/roadway_dept/countermeasures/reduce_crash_severity/listing.cfm?code=workzone https://safety.fhwa.dot.gov/roadway_dept/countermeasures/reduce_crash_severity/listing.cfm?code=cushions https://safety.fhwa.dot.gov/roadway_dept/countermeasures/reduce_crash_severity/listing.cfm?code=cushions

645.01 This work consists of locating and marking existing utilities.

Material

645.02 Replace excavated materials with equivalent materials that meet the applicable requirements of this specification.

Construction Requirements

645.03 General. Contact Miss Utility at 811 or 1-800-552-7001 at least two full business days before any excavation to have the utilities marked in the field.

If Miss Utility does not perform this service at the utilities in the field before any excavation begins. Notify the CO 48 hours before any excavation.

Perform work around Pepco underground utilities in accordance with Pepco’s Process and Procedure for Working in Close Proximity to Pepco Underground Facilities. Existing utilities have been generally located and shown on the as-built drawings provided as they are believed to exist. Exercise special care and extreme caution in order to protect and avoid damage to any utility company facilities.

Locate by test pit any utility that may conflict with the proposed work. If a conflict appears to exist, then notify the CO in writing immediately and provide information on the location and elevation of the utility so that the CO can adjust the proposed work. Restore the test pit area to its original condition.

The Government assumes no responsibility for the accuracy of locations shown in the as-built drawings. Locate and ensure the safety of all existing utilities.

Coordinate the repair of damage caused by construction with the utility owners. Pay costs associated with these repairs. See Subsection 107.02 for additional requirements.

645.04 Locating Utility. Use geophysical prospective techniques, including electromagnetic, sonic, or other energy field devices to establish alignment of utilities where applicable. When necessary, thread a metal rod through non-metallic utility pipes to locate them. Where neither method is feasible, locate the utility by perpendicular trench or test pits.

645.05 Excavation. Excavate carefully to the assume depth using hand tools as needed to avoid disturbing utilities. When excavating within roadway pavements where traffic is being maintained, excavate by air-vacuum methods or equivalent, keeping the area of disturbance to a minimum. Uncover the utility sufficiently to make accurate measurements.

645.06 Record. Describe the utility found (size, material, function), determine the elevation of the top of utility and prepare a field sketch of the pit. Indicate the date and the station and offset of the utility, noting whether the baseline or the centerline of proposed facility is being referenced. Submit one copy to the CO within 24 hours.

645.07 Marking. Mark the utility location by flags or paint. Maintain the markings, including repainting faded or damaged markings, for the duration of the project, or until the CO determines that the markings are no longer needed.

645.08 Restoration. Backfill using the excavated material or an approved equal. Thoroughly compact backfill material using compaction methods approved by the CO.

645.09 Acceptance. Locating utilities will be evaluated under Subsection 106.02.

Measurement

645.10 Measure the Section 645 items listed in the bid schedule according to Subsection 109.02.

Payment

645.11 The accepted quantities will be paid at the contract price per unit of measurement for the Section 645 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.

Progress payments for locating utilities by the lump sum will be paid as follows:

(a) 50 percent of the pay item amount will be paid after initial marking.

(b) An additional 25 percent of the pay item amount will be paid following completion of 50 percent of the original contract amount.

(c) Payment of the remaining portion of the pay item amount will be paid when the maintenance of the utility markings is no longer required as determined by the CO.
