B. Work Description

B-1 Roofing Demolition Remove existing roofing materials as detailed below. Drawing PSC-D-ATCT-A001 (Attachment J-1a) has detailed views showing the roofing system, etc. and can be used as reference.

Dispose of existing materials in a manner that meets the guidelines outlined in this document. Remove gutters and downspouts from each roofing section. Splash blocks should also be removed and will be replaced. Special precautions must be taken to ensure the air terminals, lightning roof conductors, etc. and their anchors are not damaged during any roofing work.

1. Details 1 and 2: Remove the EPDM and foam insulation down to the hot mopped vapor retarder layer. Inspect these areas during demolition for additional damage. If leaking is suspected to have penetrated thru the hot mopped vapor barrier, the gypsum board and steel deck below must be inspected. Coordinate these inspections with the RE.

2. Detail 3: Remove the EPDM.

B-2 Presumed Asbestos-Containing Materials

1. Existing roofing materials are presumed Category 1 non-friable ACM according to 40 CFR 61, Subpart M.

2. The contractor must prepare CAT I asbestos abatement specifications and project designs. The specifications and designs must be prepared by an EPA or state certified project designer. Specifications must be site specific and provide sufficient information to enforce the contract documents.

Specifications and project design must include detailed procedures to be used by the abatement contractor to safely and thoroughly abate the asbestos while assuring the safety and health of employees in the facility.

FEDERAL AVIATION ADMINISTRATION INFRASTRUCTURE SUPPORT CENTER

3. A designated competent person must supervise all work and must perform perimeter-area surveillance during each work shift. No asbestos dust must be visible. Perimeter monitoring must show that clearance levels are met or that perimeter-area levels are not higher than background levels.

4. All abatement must be performed by an abatement contractor, licensed in the State of Washington, using workers who have been trained according to EPA requirements by state accredited training providers.

5. The contractor must submit a written asbestos abatement plan that must comply with the requirements of the project specifications, and be compatible with the current facility asbestos abatement contingency plan (if applicable), Federal, state, and local requirements, and other applicable FAA orders and guidelines.

6. All asbestos waste generated must be segregated, stored, transported, and disposed of in accordance with all applicable Federal, state, and local requirements. ACM/PACM waste must be stored inside leak-proof containers in designated areas until properly transported to an approved disposal site.

The RE may stop the work with a “stop work order” if the Contractor fails to comply promptly with all or any part of the work being performed. When, in the opinion of the RE, satisfactory corrective action has been taken to correct the unsafe and unhealthy condition, the Contractor may resume work. The Contractor must not be allowed any extension of time or compensation for damages by reason of or in connection with such work stoppage.

J. Protection of Existing Vegetation, Improvements and Structures - The Contractor must take all precautions necessary to protect the existing facilities, equipment, buildings, foundations, vegetation, etc., during construction.

The schedule must be in the form of a progress chart of suitable scale to indicate the approximate percentage of work scheduled for completion at any time. The Contractor must enter on the chart the actual progress at such intervals as directed by the CO. The project schedule must include a milestone schedule for payments.

The milestones should be stated with requested reimbursement for each milestone (based upon actual costs, overhead and profit).

2. Progress Schedule - The Contractor, if requested by the CO, must submit a progress schedule at such intervals as directed by the CO. If the Contractor fails to submit a progress schedule within three (3) business days, the CO may withhold approval of progress payment estimates until the Contractor submits the required progress schedule.

P. Warranties - Documentation for the labor and material warranties must be provided to the government upon completion of the project. Warranties must provide for repair or replacement of the work, if leaking is caused by defects in materials or workmanship related to this project. Warranty must include 5-year check on the building, and must include but will not be limited to the cost of travel, man power, and repairs at the expense of the contractor. Upon the satisfactory upgrades being made, the contractor must offer a similar 5-year warranty in which they will return and complete the same process.

Warranty must continue through the life of the building.

1.5 SAFETY

OSHA and FAA safety standards will be enforced. In keeping with such standards, the Contractor must, at a minimum, provide:

A. Safety Plan - The Contractor must have and submit a Safety Plan with the purpose of maintaining a safe working environment for construction workers employed on site. The safety plan must require a statement that the current Occupation Safety and Health Act (OSHA) regulations on safety in the construction industry, OSHA Title 29, Part 1910 and Part 1926, as well as FAA safety regulations are followed. The plan will be used by the RE to insure that the work is accomplished in accordance with accepted safety practices.

F. Work Practices - Although OSHA regulations and the Contractor's Safety Plan will usually apply, the RE may consider certain work practices to be unsafe in accordance with Public Law 91-596, Part 5a and 5b. The RE may stop any operation which is in violation of the OSHA standards or fails to comply with the safety plan or other safe work practices.

G. Designated Foreman - When any construction activity is conducted at the site, the presence of a designated, competent contractor’s foreman is required at the job site. The foreman must be qualified and capable of organizing and coordinating all activities of the Contractor and his subcontractors, and keeping a safe job site.

H. Work Force - The Contractor must at all times, when construction activities are conducted, have a substantial number of workers for each task to proceed expeditiously and without generating delay, for lack of man-power.
