The Contractor shall submit tracking documentation prior to project completion. A sample form is attached below that will meet all documentation requirements of the Contractor. The documentation shall be submitted to the Public Works Department (PWD) Environmental Division.

2.10 Permits and Outages Any man-made cut, cavity, trench or depression in the earth’s surface formed by earth removal requires an excavation permit. In addition, the Contractor shall provide a third party utility location. Any utility or HVAC outage affecting inhabited work space, inhabited living space, or exit from an inhabited work space/living space requires an Outage Permit. Any “Hot Work” (welding, cutting, soldering/brazing, blow torches, etc.) requires a “Hot Work” permit issued to the Contractor by the Fire Prevention office (850-623-7856). Permission to interrupt any utility, communication, operational or traffic service or pattern shall be requested in writing at least 10 working

01010 - 12 days prior to the date of the desired interruption. The Contractor shall receive approval in writing from the Contracting Officer and/or FEAD POC before requested interruption may be implemented.

The documentation of products shall include type of product/equipment, size/capacity, cost of the product/equipment and other information that would help identify/quantify energy savings/efficiency.

2.12 Utility Location and Damage Avoidance For all excavation and subsurface work, the contractor shall physically verify underground utility locations, including utility depth, by hand digging using wood or fiberglass handled tools when any adjacent construction work is expected to come within 3 feet of the underground system.

Contractor shall perform a Utility Quality Level A survey prior to any excavations as defined in ASCE 38-02.

Contractors are reminded that Utility Quality Level A surveys involves precise horizontal and vertical locations of utilities at a level of accuracy (15mm) that can normally only be achieved through the use of test holes. Sunshine 811 or equivalent utility coordinator services alone do not meet the Utility Quality Level A requirement.

In addition to the Utility Quality Level A survey, contractor shall enlist a third party, independent, private utility locating company to confirm the non-existence of subsurface utilities in all excavation areas.

Whenever contract work involves chipping, saw cutting, or core drilling through concrete, bituminous asphalt or other impervious surfaces, the existing utility location must be coordinated with station utility departments in addition to location and depth verification by a third party, independent, private locating company. The third party, independent, private locating company must locate utility depth by use of Ground Penetrating Radar (GPR), X-ray, bore scope, or ultrasound prior to the start of demolition and construction. Outages to isolate utility systems must be used in circumstances where utilities are unable to be positively identified. The use of historical drawings does not alleviate the Contractor from meeting this requirement.

Contractor shall maintain survey-verified markings throughout the duration of the project. RETURN AREAS DAMAGED AS A RESULT OF CONSTRUCTION UNDER

THIS CONTRACT TO THEIR ORIGINAL CONDITION AT NO ADDITIONAL COST TO

THE GOVERNMENT.
