PART 3     EXECUTION

3.01    EXAMINATION
        A. Verify that the surfaces and site conditions are ready to receive work.
        B. Verify that the deck is supported and secured.
        C. Verify that the deck is clean and smooth, free of depressions, waves, or projections, and properly
           sloped to drains, valleys, eaves, scuppers or gutters.
        D. Verify that the deck surfaces are dry and free of ice or snow.
        E. Verify that all roof openings or penetrations through the roof are solidly set, and that all flashings are
           tapered.

3.02    SUBSTRATE PREPARATION
        A. Structural Concrete Deck
           1. Minimum deck thickness for structural concrete is 4" (10.2 cm).
           2. Only poured in place concrete decks that provide bottom side drying are acceptable. Decks that
              are installed over non-vented metal decks or pans that remain in place may trap moisture in the
              deck beneath the roof system and are not acceptable.
           3. The roof deck shall be properly cured prior to application of the roofing system; twenty-eight (28)
              days is normally required for proper curing. Curing agents must be checked for compatibility with
              roofing materials. Prior to the installation of the roof assemblies, GAFMC recommends the
              evaluation of the surface moisture and deck's dryness through the use of ASTM D-4263 or hot
              bitumen test.
           4. The deck must be smooth, level and cannot be wet or frozen. If deck is determined to be wet, it
              must be allowed to dry.
           5. Treat cracks greater than 1/8" (3 mm) in width in accordance with the deck manufacturer's
              recommendations.
           6. Sumps for the roof drains shall be provided in the casting of the deck.
           7. When insulation or roofing is to be adhered with hot asphalt, prime the deck with asphalt/concrete
               primer, ASTM D41 at the rate of one gallon per 100 square feet (0.4 L/m2). Allow the primer to
              dry prior to the application of the roofing system.
           8. In all retrofit roof applications, it is required that deck be inspected for defects. Any defects are to
               be corrected per the deck manufacturer's recommendations prior to the new roof application.

3.03     INSTALLATION - GENERAL
         A. Install GAFMC's EverGuard® TPO roofing system according to all current application requirements
            in addition to those listed in this section.
         B. GAFMC EverGuard® TPO Specification #: T-FA-N-I-3P6-60FB
         C. Start the application of membrane plies at the low point of the roof or at the drains, so that the flow of
            water is over or parallel to, but never against the laps.

3.04     BITUMEN HANDLING
         A. Do not mix different types of asphalt.
         B. Use only ASTM D 312, Type III or Type IV Steep Asphalt. Type III asphalt may be used on slopes up
            to Va" per foot (4cm/m). Type IV asphalt must be used on all slopes greater than 1/2" per foot (4
            cm/m).
         C. Application with hot asphalt requires continuous, uniform interply mopping rates of 25 lbs. +/- 20%
            per 100 square feet of roof area (1.2 kg/m2).
         D. Application temperature of the asphalt must be at the Equiviscous Temperature (EVT) with a
            tolerance of +/-25°F (13.9°C), at which a viscosity of 125 centipoise is attained. When using
             mechanical asphalt applicators, the target viscosity should be 75 centipoise.

October 16, 2009                                  07540 - 4                   THERMOPLATIC SINGLE-PLY ROOFING
        E. For all SBS modified asphalt flashings; the minimum application temperature of the asphalt must be
                                                                                                                          J
           at the EVT or 425°F (218°C), whichever is greater, with a rolling bank (puddle) of mopping asphalt
           across the full width of the roll.
        F. Do not heat the asphalt to or above its flash point or hold the asphalt at temperatures above the
           finished blowing temperature for more than 4 hours.
        G. Do not keep heated tankers above 325°F (163°C) overnight.

3.05    INSULATION - GENERAL
        A. Do not apply roof insulation or roofing until all other work trades have completed jobs that require
           them to traverse the deck on foot or with equipment. A vapor retarder coated lightly with asphalt
           may be applied to protect the inside of the structure prior to the insulation and final roofing
           installation. Before the application of the insulation, any damage or deterioration to the vapor
           retarder must be repaired.
        B. Do not install wet, damaged or warped insulation boards.
        C. Install insulation boards with staggered board joints in one direction (unless taping joint).
        D. Install insulation boards snug. Gaps between board joints must not exceed Vi" (6 mm). All gaps in
           excess of Vi" (6 mm) must be filled with like insulation material.
        E. Wood nailers must be 3-1/2" (8.9 cm) minimum width or 1" (25 mm) wider than metal flange. They
           shall be of equal thickness as the insulation, and be treated for rot resistance. All nailers must be
           securely fastened to the deck.
        F. Do not kick insulation boards into place.
        G. Miter and fill the edges of the insulation boards at ridges, valleys and other changes in plane to
           prevent open joints or irregular surfaces. Avoid breaking or crushing of the insulation at the corners.
        H. Insulation should not be installed over new lightweight insulating concrete.
        I. Roof tape, if required over insulation joints, must be laid evenly, smoothly and embedded in a
           uniform coating of hot steep asphalt with 4" (10.2 cm) end laps. Care must be taken to assure                      x
           smooth application of tape, and full embedment of the tape in the asphalt.                                       _M
                                                                                                                          >

           2. Penetration flashings constructed of un-reinforced membrane are typically installed in two
                sections, a horizontal piece that extends onto the roofing membrane and a vertical piece that
                extends up the penetration. The two pieces are overlapped and hot-air welded together.
           3. The un-reinforced membrane flashing shall be adhered to the penetration surface. Apply
                bonding adhesive at a rate resulting in 60 square feet/gallon of finished roofing material for
                 solvent-based bonding adhesives, and at a rate of 125 square feet/gallon of finished roofing
                 material for water-borne bonding adhesive. Apply bonding adhesive to both the underside of the
                membrane and the substrate surface at 120 square feet per gallon (Solvent Based) and 250
                 square feet per gallon (Water Based). A greater quantity of bonding adhesive may be required
                 based upon the substrate surface condition. The bonding adhesive must be allowed to dry until
                tacky to the touch before flashing membrane application.

3.2        PREPARATION
      A.   Surface Cleaning of Joints: Clean out joints immediately before installing joint sealants to
           comply with joint-sealant manufacturer's written instructions and the following requirements:
           1.     Remove ail foreign material from joint substrates that could interfere with adhesion of
                  joint sealant, including dust, paints (except for permanent, protective coatings tested and
                  approved for sealant adhesion and compatibility by sealant manufacturer), old joint
                  sealants, oil, grease, waterproofing, water repellents, water, surface dirt, and frost.
           2.     Clean porous joint substrate surfaces by brushing, grinding, mechanical abrading, or a
                  combination of these methods to produce a clean, sound substrate capable of developing
                  optimum bond with joint sealants. Remove loose particles remaining after cleaning
                   operations above by vacuuming or blowing out joints with oil-free compressed air.
                   Porous joint substrates include the following:
                  a.      Concrete.
                   b.     Masonry.
                   c.     Unglazed surfaces of ceramic tile.
                   d.     Exterior insulation and finish systems.
           3.      Remove laitance and form-release agents from concrete.
           4.      Clean nonporous joint substrate surfaces with chemical cleaners or other means that do
                   not stain, harm substrates, or leave residues capable of interfering with adhesion of joint
                   sealants. Nonporous joint substrates include the following:
                  a.      Metal.
                   b.     Glass.
                   c.     Porcelain enamel.

           indicated by preconstruction joint-sealant-substrate tests or prior experience. Apply primer to
           comply with joint-sealant manufacturer's written instructions. Confine primers to areas of joint-
           sealant bond; do not allow spillage or migration onto adjoining surfaces.
      C.   Masking Tape: Use masking tape where required to prevent contact of sealant or primer with
           adjoining surfaces that otherwise would be permanently stained or damaged by such contact or
           by cleaning methods required to remove sealant smears. Remove tape immediately after
           tooling without disturbing joint seal.

           written recommendations.

3.4        FIELD QUALITY CONTROL
      A.   Field-Adhesion Testing: Field test joint-sealant adhesion to joint substrates as follows:
           1.     Extent of Testing: Test completed and cured sealant joints as follows:
                  a.      Perform 10 tests for the first 1000 feet (300 m) of joint length for each kind of
                          sealant and joint substrate.
                  b.       Perform 1 test for each 1000 feet (300 m) of joint length thereafter or 1 test per
                           each floor per elevation.
           2.     Test Method: Test joint sealants according to Method A, Field-Applied Sealant Joint
                  Hand Pull Tab, in Appendix X1 in ASTM C 1193 or Method A, Tail Procedure, in
                  ASTM C 1521.
                  a.       For joints with dissimilar substrates, verify adhesion to each substrate separately;
                           extend cut along one side, verifying adhesion to opposite side. Repeat procedure
                           for opposite side.
           3.     Inspect tested joints and report on the following:
                  a.       Whether sealants filled joint cavities and are free of voids.
                  b.       Whether sealant dimensions and configurations comply with specified
                           requirements.
                  c.       Whether sealants in joints connected to pulled-out portion failed to adhere to joint
                           substrates or tore cohesively. Include data on pull distance used to test each kind
                           of product and joint substrate. Compare these results to determine if adhesion
                           passes sealant manufacturer's field-adhesion hand-pull test criteria.
           4.      Record test results in a field-adhesion-test log. Include dates when sealants were
                   installed, names of persons who installed sealants, test dates, test locations, whether
                  joints were primed, adhesion results and percent elongations, sealant fill, sealant
                   configuration, and sealant dimensions.
           5.      Repair sealants pulled from test area by applying new sealants following same
                   procedures used originally to seal joints. Ensure that original sealant surfaces are clean
                   and that new sealant contacts original sealant.
      B.   Evaluation of Field-Adhesion Test Results: Sealants not evidencing adhesive failure from
           testing or noncompliance with other indicated requirements will be considered satisfactory.
           Remove sealants that fail to adhere to joint substrates during testing or to comply with other
           requirements. Retest failed applications until test results prove sealants comply with indicated
           requirements.

3.5        CLEANING
