C. SCOPE OF WORK:

Muniz ANG Station, Puerto Rico, has experienced roof damage due to Hurricanes Irma and Maria.

The completion of the following roof repairs are required to preserve buildings.

Asbestos Abatement: Asbestos containing materials (ACM)/debris have not been inspected on the roofs for the buildings on Muniz ANG Station. Any ACM that may be disturbed during the course of this project shall be abated by a certified abatement company that has submitted the required qualification documentation and has been approved to perform abatement work by the COR. An asbestos work plan must be submitted to the COR prior to starting any work. Pre and Post abatement visual inspection must be scheduled with the COR office at least 24 hours in advance and any discrepancies found as a result shall be corrected by the contractor, at no additional cost to the government, before proceeding. The contractor will remove the ACM in accordance with 29 CFR 1926.1101, as outlined in DAQ R307-801, Puerto Rico standards, as well as base guidelines. Upon http://www.wbdg.org/ffc/dod/unified-facilities-guide-specifications-ufgs completion of the asbestos removal, all surfaces inside the regulated area shall be visibly clean of any debris and or dust. Entire work area will be HEPA vacuumed and wet cleaned prior to the final visual inspection and encapsulation. Critical barriers will cover all openings and penetrations inside the regulated work area and will remain in place until the areas have been released as clean, first by a visual inspection and then by aggressive air clearance sampling. An independent, third party consulting firm hired by the contractor will run the aggressive air clearance samples. A three stage decon unit will be attached to each enclosure/phase prior to starting any asbestos removal. The decon unit will be equipped with hot and cold running water. Shower and or residual water will be filtered down to 5 microns before being discharged into a sanitary sewer drain. Regulated areas will be demarcated with asbestos warning signs and barrier tape. Contractor will remove and properly package the ACM while adequately wet. Daily abatement project documentation/logs and all air monitoring results must be submitted to the COR at the completion of the project. All asbestos waste shall be disposed of at an approved landfill and all waste manifests shall be signed by the contractor with a signed copy being returned to the case COR within 30 days of the waste being disposed of.

PART 3 EXECUTION

3.1 EXAMINATION AND PREPARATION

3.1.1 Surface Inspection

Surfaces shall be clean, smooth, and dry. Check roof deck surfaces, including surfaces sloped to roof drains and outlets, for defects before starting work.

The Contractor shall inspect and approve the surfaces immediately before starting installation. Prior to installing insulation, perform the following:

a. Examine steel decks to ensure that panels are properly secured to structural members and to each other and that surfaces of top flanges are flat or slightly convex.

b. Prior to installing any roof system on a concrete deck, conduct a test per ASTM D4263. The deck is acceptable for roof system application when there is no visible moisture on underside of plastic sheet after

24 hours.

3.1.2 Surface Preparation

Correct defects and inaccuracies in roof deck surface to eliminate poor drainage and hollow or low spots and perform the following:

a. Install wood nailers the same thickness as insulation at eaves, edges, curbs, walls, and roof openings for securing cant strips, gravel stops, gutters, and flashing flanges.

b. Cover steel decks with a layer of insulation board of sufficient thickness to span the width of a deck rib opening, and conforming to fire safety requirements. Secure with piercing or self-drilling, self-tapping fasteners of quantity and placement conforming to

FM APP GUIDE. Insulation joints parallel to ribs of deck shall occur on solid bearing surfaces only, not over open ribs.

3.4 INSULATION INSTALLATION

Apply insulation in two layers with staggered joints when total required thickness of insulation exceeds 1/2 inch. Lay insulation so that continuous longitudinal joints are perpendicular to direction of felts for the modified bituminous roofing, as specified in Section 07 52 00, "

MODIFIED BITUMINOUS MEMBRANE ROOFING", and end joints of each course are staggered with those of adjoining courses. When using multiple layers of insulation, joints of each succeeding layer shall be parallel and offset in both directions with respect to layer below.Keep insulation 1/2 inch clear of vertical surfaces penetrating and projecting from roof surface.

3.4.3 Installation Using Only Mechanical Fasteners

Secure total thickness of insulation with penetrating type fasteners.

SECTION 07 22 00 Page 7

3.4.4 Special Precautions for Installation of Foam Insulation

3.4.4.1 Polyisocyanurate Insulation

Where polyisocyanurate foam board insulation is provided, install 1/2 inch glass mat gypsum roof board over top surface of foam board insulation.

Stagger joints of insulation with respect to foam board insulation below.

3.4.5 Cant Strips

Where indicated, provide cant strips at intersections of roof with walls, parapets, and curbs extending above roof. Wood cant strips shall bear on and be anchored to wood blocking. Fit cant strips flush against vertical surfaces. Where possible, nail cant strips to adjoining surfaces. Where cant strips are installed against non-nailable materials, install in an approved adhesive.

3.4.6 Tapered Edge Strips

Where indicated, provide edge strips in the right angle formed by junction of roof and wood nailing strips that extend above level of roof. Install edge strips flush against vertical surfaces of wood nailing strips. Where possible, nail edge strips to adjoining surfaces. Where installed against non-nailable materials, install in an approved adhesive.

3.5 PROTECTION

3.5.1 Protection of Applied Insulation

Completely cover each day's installation of insulation with the finished roofing specified in Section 07 52 00 on same day. Do not permit phased construction. Protect open spaces between insulation and parapets or other walls and spaces at curbs, scuttles, and expansion joints, until permanent roofing and flashing are applied. Do not permit storing, walking, wheeling, or trucking directly on insulation or on roofed surfaces. Provide smooth, clean board or plank walkways, runways, and platforms near supports, as necessary, to distribute weight to conform to indicated live load limits of roof construction. Exposed edges of the insulation shall be protected by cutoffs at the end of each work day or whenever precipitation is imminent. Cutoffs shall be 2 layers of bituminous-saturated felt set in plastic bituminous cement. Fill all profile voids in cut-offs to prevent entrapping of moisture into the area below the membrane. Cutoffs shall be removed when work is resumed.

3.5.2 Damaged Work and Materials

Restore work and materials that become damaged during construction to original condition or replace with new materials.

3.6 INSPECTION

The Contractor shall establish and maintain an inspection procedure to assure compliance of the installed roof insulation with the contract requirements. Any work found not to be in compliance with the contract shall be promptly removed and replaced or corrected in an approved manner.

Quality control shall include, but not be limited to, the following:

a. Observation of environmental conditions; number and skill level of

SECTION 07 22 00 Page 8 insulation workers; start and end time of work.

b. Verification of certification, listing or label compliance with FM P9513.

c. Verification of proper storage and handling of insulation materials before, during, and after installation.

d. Inspection of mechanical fasteners; type, number, length, and spacing.

e. Coordination with other materials, cants, sleepers, and nailing strips.

f. Inspection of insulation joint orientation and laps between layers, joint width and bearing of edges of insulation on deck.

g. Installation of cutoffs and proper joining of work on subsequent days.

h. Continuation of complete roofing system installation to cover insulation installed same day.
