3.6 EXCAVATIONS

3.6.1 Utility Locations

Prior to digging, the appropriate digging permit must be obtained.  All underground utilities in the work area must be positively identified by a private utility locating service in addition to any station locating service and coordinated with the station utility department.  Any markings made during the utility investigation must be maintained throughout the contract.  Locate utilities in accordance with Section 01 14 00.05 20 WORK RESTRICTIONS FOR DESIGN-BUILD.

3.6.2 Utility Location Verification

The Contractor must physically verify underground utility locations by hand digging using wood or fiberglass handled tools when any adjacent construction work is expected to come within three feet of the underground system.  Digging within 0.061 m (2 feet) of a known utility must not be performed by means of mechanical equipment; hand digging shall be used.  If construction is parallel to an existing utility the utility shall be exposed by hand digging every 30.5 m (100 feet) if parallel within 1.5 m (5 feet) of the excavation.

3.7 UTILITIES WITHIN CONCRETE SLABS

Utilities located within concrete slabs or pier structures, bridges, and the like, are extremely difficult to identify due to the reinforcing steel used in the construction of these structures.  Whenever contract work involves concrete chipping, saw cutting, or core drilling, the existing utility location must be coordinated with station utility departments in addition to a private locating service.  Outages to isolate utility systems shall 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.

3.8 ELECTRICAL

3.8.1 Conduct of Electrical Work

Underground electrical spaces must be certified safe for entry before entering to conduct work.  Cables that will be cut must be positively identified and de-energized prior to performing each cut. Positive cable identification must be made prior to submitting any outage request for electrical systems.  Arrangements are to be coordinated with the Contracting Officer and Station Utilities for identification.  The Contracting Officer will not accept an outage request until the Contractor satisfactorily documents that the circuits have been clearly identified.  Attachment of temporary grounds shall be in accordance with ASTM F855 and IEEE 1048.  Perform all high voltage cable cutting remotely using hydraulic cutting tool.  When racking in or live switching of circuit breakers, no additional person other than the switch operator will be allowed in the space during the actual operation.  Plan so that work near energized parts is minimized to the fullest extent possible.  Use of electrical outages clear of any energized electrical sources is the preferred method.  When working in energized substations, only qualified electrical workers shall be permitted to enter.  When work requires Contractor to work near energized circuits as defined by the NFPA 70, high voltage personnel must use personal protective equipment that includes, as a minimum, electrical hard hat, safety shoes, insulating gloves with leather protective sleeves, fire retarding shirts, coveralls, face shields, and safety glasses.  In addition, provide electrical arc flash protection for personnel as required by NFPA 70E.  Insulating blankets, hearing protection, and switching suits may also be required, depending on the specific job and as delineated in the Contractor's AHA.

3.9 WORK IN CONFINED SPACES

In addition to the requirements  of Section 06.I of USACE EM 385-1-1, OSHA 29 CFR 1910.146 and OSHA 29 CFR 1926.21(b)(6) the Contractor shall comply with the following.  Any potential for a hazard in the confined space requires a permit system to be used.

1. Entry Procedures.  Prohibit entry into a confined space by personnel for any purpose, including hot work, until the qualified person has conducted appropriate tests to ensure the confined or enclosed space is safe for the work intended and that all potential hazards are controlled or eliminated and documented.  (See Section 06.I.06 of USACE EM 385-1-1 for entry procedures.) All hazards pertaining to the space shall be reviewed with each employee during review of the AHA.
2. Forced air ventilation is required for all confined space entry operations and the minimum air exchange requirements must be maintained to ensure exposure to any hazardous atmosphere is kept below its' action level.
3. Sewer wet wells require continuous atmosphere monitoring with audible alarm for toxic gas detection.

3.10 ERGONOMICS CONSIDERATIONS DURING DESIGN PHASE

Facilities, processes, job tasks, tools and materials shall be designed to reduce or eliminate work-related musculoskeletal (WMSD) injuries and risk factors in the workplace.  Designs shall ensure facility maintenance access is designed to reduce WMSD risk factors to the lowest level possible. In addition to the detailed requirements included in the provisions of this contract, the design work shall incorporate the requirements of MIL-STD-1472F, DOD–HDBK 743A and ANSI/HFES 100.
