2. GENERAL:

2.1 The Contractor must provide supervision, labor, material and equipment required to perform all work for the following project: AHU #3 above room 39 is down. This is needed for COMMS Equipment. All work must be done in a manner to provide a complete, usable and finished end product. See paragraph “7. WORK REQUIREMENTS” for an expanded and detailed Scope of Work.

2.2 The Contractor must comply with the requirements and specifications of the most current Contract.

2.3 A Pre-Proposal site meeting may be scheduled at the project site to review and discuss the Scope of Work and assess existing field conditions, prior to Award of this Task Order.

2.4 Existing reference drawings may be available upon request. Reference drawings must be used for informational purposes only, and may not accurately reflect current as-built conditions. The Contractor must not solely rely on the reference drawings to determine existing conditions, but must field verify all existing conditions pertinent to the project.

2.5 All work must be performed in accordance with, but not limited to, standard industry practices, applicable local, state and federal codes, laws and regulations, contract specifications, Unified Facilities Criteria (UFC’s) and Unified Facilities Guide Specifications (UFGS’s).

2.6 Supervision: Have a Supervisor fluent in English on the job site during working hours at all times.

The Supervisor must be a United States Citizen or a Documented Legal Resident of the United States of America.

SCOPE OF WORK 24 March 2023 Page 3 of 13

3. SPECIAL SCHEDULING REQUIREMENTS/WORK PROCEDURES:

3.1 The project Contract Completion Date (CCD) must be 120 calendar days from Award of this Task

Order.

3.2 Existing and adjacent spaces to remain in operation during construction must be protected from damage, dust, and debris at all times. Damage to any existing spaces, finishes, items, furniture and equipment, as a result of the Contractor’s operations, must be replaced in-kind by the Contractor at no expense to the Government.

3.3 UTILITIES LOCATION AND VERIFICATION (Exterior): 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, prior to any digging. Any markings made during the utility investigation must be maintained throughout the contract. 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 2 feet of a known utility must not be performed by means of mechanical equipment; hand digging must be used. If construction is parallel to an existing utility expose the utility by hand digging every 100 feet if parallel within 5 feet of the excavation.

3.4 UTILITIES LOCATION AND VERIFICATION (Other): 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 must be used in circumstances where utilities are unable to be positively identified. The use of historical reference drawings does not alleviate the contractor from meeting this requirement. The contractor must perform positive identification and locating of existing utilities prior to any concrete chipping, saw cutting or core drilling of any kind.

3.5 The Contractor must utilize existing isolation valves (if available and usable/pressure holding) and other types of non-destructive system(s) isolation to minimize the draining of potable water, chilled water, condenser water, heating water piping systems to provide the necessary system connections and disconnections. All water drained from existing systems must be captured and containerized for sampling. Prior to any discharges, the Contractor must submit the Water Test Report(s) to the NAS Oceana Waste Water Manager (through the Contracting Officer) for determination and documentation of disposal method(s). The test report submittal(s) must include an estimate of volume (gallons) and date of scheduled discharge(s). The contractor must provide the disposal of all drained water in accordance with all applicable federal, state and local regulations.

3.6 Refrigerants in the HVAC system to be demolished must be evacuated prior to disposal. Remove air conditioning, refrigeration, and other equipment containing refrigerants without releasing chlorofluorocarbon refrigerants to the atmosphere in accordance with the Clean Air Act Amendment of 1990. Refrigeration, and other equipment containing refrigerants and dispose of in accordance with UFGS 02 41 00 DEMOLITION AND DECONSTRUCTION.

3.7 In the event that hazardous waste is generated or mobilized, the hazardous waste program manager must be contacted for the appropriate guidance. In addition, any movement of soil/fill material outside of project boundaries, meaning both soil brought onsite and soil from the site relocated to other areas, SCOPE OF WORK 24 March 2023 Page 4 of 13 must be coordinated with the hazardous waste program manager to ensure environmental compliance.

3.8 In the event asbestos containing material (ACM) or presumed asbestos containing material (PACM) is discovered, all work shall be stopped and the contractor shall set up a temporary regulated area around the ACM/PACM and contact the PWD Oceana Asbestos Program Manager.

3.9 Pre-Outage Coordination Meeting:

Apply for outages at least 15 days in advance to the Contracting Officer. As a minimum, the request must include the location of outage, areas being affected, duration of outage and any necessary sketches. Any/all outage requests must be approved by the Contracting Officer prior to starting the work. Once approved, and prior to beginning work on the system requiring shut down, attend a pre-outage coordination meeting with the Contracting Officer to review scope of work and the lock-out/tag-out procedures for worker protection. No work will be performed on energized electrical circuits unless proof is provided that no other means exist.

3.10 Control of Hazardous Energy (Lock-out/Tag-out):

Provide and operate a Hazardous Energy Control Program (HECP) in accordance with EM 385-1-1 Section 12, 29 CFR 1910.333, 29 CFR 1915.89, and paragraph HAZARDOUS ENERGY CONTROL

Interruption of alarm or communications functions at the fire alarm watch office is prohibited.

3.12 In general terms, demolition work and the use of word “demolish”, must include the removal and effective management and disposal of existing construction and or structures. Contractor must take care to prevent damage to existing utilities and construction that are not scheduled for demolition. If damage occurs, the Contractor must make repairs, or replacement with new, to the satisfaction of the Contracting Officer and at no cost to the Government.
