DIVISION 01 – GENERAL CONDITIONS

1. Scope of Work:

1.1 Perform work in accordance with this Scope and the attached specifications and drawings.

Work includes: removal of clerestories and replacement with glazed windows, siding removal and replacement, roof replacement, and associated construction and abatement activities.

1.1.1 Due to the existence of lead paint on surfaces and potential for Asbestos containing materials being encountered in the construction activities, the contractor will need to provide environmental plans/controls for this project. Sampling and analysis of HAZWASTE is required.

HAZWASTE will be disposed of by the Coast Guard. Asbestos containing materials will be disposed of by the contractor.

2. HAZMAT Considerations

2.1 The below is a summary of the Hazmat issues in the hangar.

2.1.1 Metal components coated with lead paint, which require attachments, cutting or welding.

Remove lead paint and dispose of as HAZWASTE. Methyl Ethyl Ketone (MEK) or other similar type halogenated solvents are not allowed.

2.1.2 Dust and loose paint flakes on all surfaces, including structural steel, has the potential to contain lead or ACM. The inside of the Hangar has been cleaned in prior years, however dust and debris could still be present. Prior cleanings were only performed to facilitate the work to be performed under the prior construction contract, and never were anticipated to provide a dust free surface. The contractor shall perform a site assessment, sampling or other means as needed to determine the procedures, level of worker protection, and building occupant protection required in the performance of the work. General cleaning or abatement of the building is not required.

The only abatement required is that necessary to facilitate the work.

2.1.3 For surfaces requiring painting or welding (structural steel, bracings, etc), and concrete walls: these surfaces could currently be covered with dust or existing paint that may contain lead.

2.1.4 The substrate materials behind the existing metal siding may contain asbestos containing materials. The metal siding may have been placed over the top of preexisting ACM siding.

Disturbance by siding removal and fastening activities, may create an asbestos hazard.

2.1.5 HAZWASTE will be delivered to CG for disposal.

2.1.6 Asbestos containing debris shall be disposed of off-base by the contractor.

2.1.7 Floor debris; the floor below the work area is to be swept upon completion of the work.

2.1.8 Metals shall be recycled.

2.1.9 See also the Sections pertaining to Lead and Asbestos, and the Paragraphs on Environmental Plans in this Specification Division.

3. Notes on work items:

a. At completion of work, all affected areas shall be cleaned and swept. The roof shall be swept, and any gutters cleaned.

b. The area below the clerestories has live electrical equipment. Weather precautions are required.

c. The contractor’s laydown area is the South face of Hangar 3. This area may be used by the contractor. Do not block entrances. Provide traffic/pedestrian lanes to/from the building and the aircraft ramp. The contractor shall erect a temporary barrier to demark their work area.

d. The Hangar is an active aircraft hangar. All adjacent spaces are occupied, and aircraft/people move past the work area frequently. Specific procedures are required for access, hotwork, and building occupant protection that will impact the contractor’s ability to perform the work. For instance; typically no hotwork can be performed in the hangar, unless all aircraft are moved outside. This will affect the contractor’s ability to schedule the work.

e. Temporary shed covers shall be constructed at the entry points to the Hangar deck, from the office/shop areas. Covers shall protect pedestrians from falling objects, and shall be rigid construction.

f. The interior wall of the Hangar has additional overhead doors and equipment requiring continued use during construction. Provide appropriate overhead protection for these openings and equipment.

g. The aircraft bays adjacent to the work area are not available for dedicated contractor use.

h. During hot work which may result in sparks falling on the Hangar deck; provide a live fire watch on the hangar deck during welding activities.

j. The Task Order work includes relocating several antennae wires. The contractor should plan for a “hot” cutover, and no more than a one work day outage. Due to operational nature of Hangar, specific written advance approval for any antenna outage is to be obtained from the COTR in advance.

4. SUBMITTALS

a. Sequencing of Construction Plan. Submit a sequencing plan for construction activities. Plan shall show sequence of work, any required relocation of Coast Guard owned equipment, and how the various trades will be coordinated. Include a detailed schedule and a specific sequence of work for the coordination of all trades involved in the work. Schedule shall indicate restrictions to building occupants, and shall specifically show how the contractor intends to provide weather protection for the inside of the Hangar during the work.

1.5 DUST AND DEBRIS CONTROL

Prevent the spread of dust and debris to occupied portions of the building and/or on airfield pavements and avoid the creation of a nuisance or hazard in the surrounding area. Do not use water if it results in hazardous or objectionable conditions such as, but not limited to, ice, flooding, or pollution. Sweep pavements as often as necessary to control the spread of debris that may result in foreign object damage potential to aircraft.

1.6 PROTECTION

1.6.1 Traffic Control Signs

Where pedestrian or aircraft safety is endangered in the area of removal work, use traffic barricades with flashing lights. Anchor barricades in a manner to prevent displacement by wind, jet or prop blast.

1.6.2 Existing Work

Before beginning any demolition work, survey the site and examine the drawings and specifications to determine the extent of the work. Record existing work in the presence of the COTR showing the condition of structures and other facilities adjacent to areas of alteration or removal. Photographs will be acceptable as a record of existing conditions.

Take necessary precautions to avoid damage to existing items to remain in place, to be reused. Repair or replace damaged items as approved by the COTR. Coordinate the work of this section with all other work indicated. Construct and maintain shoring, bracing, lay-down roof protection and supports as required. Ensure that structural elements are not overloaded. Increase structural supports or add new supports as may be required as a result of any cutting, removal, or demolition work performed under this contract. Do not overload structural elements or pavements.

Provide new supports and reinforcement for existing construction weakened by demolition or removal work. Repairs, reinforcement, or structural replacement require approval by the COTR.

1.7 BURNING: BURNING IS NOT PERMITTED.

1.8 FOREIGN OBJECT DAMAGE (FOD)

Aircraft and aircraft engines are subject to FOD from debris and waste material lying on airfield pavements. Remove all such materials that may appear on operational aircraft pavements due to the Contractor's operations. If necessary, the COTR may require the Contractor to install a temporary barricade at the Contractor's expense to control the spread of FOD potential debris. The barricade must include a fence covered with a fabric designed to stop the spread of debris. Anchor the fence and fabric to prevent displacement by winds or jet/prop blasts. Remove barricade when no longer required.
