      and a new layer of wood fiberboard insulation shall be applied using offset joints, so that each
      layer breaks joints to a minimum of six inches (6") both ways with the preceding layer, and
      immediately walked in place. The new layer of insulation shall run perpendicular to the existing
      insulation.

     The new layer of insulation shall be applied over the existing insulation using offset joints, so that
     each layer breaks joints to a minimum of six inches (6") both ways with the preceding layer.
  5. Add sub-paragraph “C” to section 3.08 Application of Ply Sheets as follows:
     MECHANICALLY FASTENED BASE PLY AT LIGHTWEIGHT DECKS
     Substrate shall be covered with specified base sheet mechanically fastened as follows:

     Securement shall conform to the ASCE 7 criteria for wind uplift as dictated by wind zone
     applicable to location of project. Fasteners and fastening patterns shall be determined by
     building height, location and geographical area of the United States. It is the contractor's
     responsibility to consult current publications, literature, and bulletins of IBC and the fastener
     manufacturer that are in effect at the time of this project.
  6. Add paragraph “3.4” to Part 3 Execution as follows:
     SELF-ADHERING WELDED-SEAM VERTICAL WALL FLASHING
     (FOR USE APPROXIMATELY 8" ABOVE THE FINISHED ROOF LINE AND EXTENDING
     UPWARD)
     White self-adhered welded seam membrane flashing shall be installed on the vertical beginning
     approximately eight inches (8") above the finished roof line (where the coal-tar elastomeric
     membrane is terminated), with length of run not to exceed the width of the material roll. Strapped
     flashing method shall be installed in strict accordance with the manufacturer's recommendations.

      The termination bar used to terminate the eight inch (8") high base flashing shall be used to
      terminate the lower edge of the vertical flashing. This will cause the termination bar to be buried
      at the eight inch (8") minimum height. Care should be taken to ensure the top edge of the base
      flashing and bottom edge of the vertical flashing are both secured.

      All existing substrates receiving flashing membrane shall be clean and primed with asphalt
      primer, prior to application.
ADDENDUM NO. ONE                                                                   NOVEMBER 3, 2010

PLANO ISD                                                                    ATTACHMENTS: (9 PAGES)

        All substrates receiving welded-seam flashing membrane shall be clean and primed with asphalt
        primer, prior to application.

        Flashing membrane shall be installed with Type IV glass felt as an underlayment. The Type IV
        glass felt shall be set in hot asphalt and properly primed prior to the application of the self-
        adhered welded seam membrane.

        All vertical flashing lap seams of the self-adhered welded seam membrane shall be hot air
        welded. NOTE: Once the CTEM membrane has been contaminated with hot asphalt, it is not
        possible to clean the asphalt off and hot air weld it for a long term effectiveness. A patch of
        CTEM must be welded over the area large enough to be welded one and one-half inches (1-1/2")
        past any contaminated area.

        Flashing laps shall be minimum three inch (3") width, no maximum. Hot-air weld of flashing lap
        shall be minimum one and one-half inch (1-1/2") width, no maximum.

        Immediately following the laying of the self-adhered welded seam membrane, it shall be pressed
        or rolled in the width direction of the membrane. This will prevent excessive entrapment of air
        beneath the membrane. The pressing or rolling shall be in the width direction and with the laps
        so as not to buck the laps.

        Any flashing extending further than eight inches (8") up onto a vertical surface shall be installed
        using the strapped method and must be fastened with a termination bar or installed up and over
        the parapet wall and fastened to the nailer on the outside of the wall.

        The self adhered welded seam flashing membrane shall be run up the wall in three foot (3')
        widths, run under the coping cap and be terminated on the outside of the wall six inches (6") on
        center; then the coping cap shall be reset. All side laps are to be hot-air welded.

        Hot-air Welding Laps:
        When using a hand-held hot-air welder, the seams should be pressed together using a hand-held
        roller. The speed and temperature settings of the welding equipment can be affected by the
        weather conditions at the site of application, therefore, these parameters should be set by the
        contractor by using two (2) pieces of self-adhered welded seam membrane. Minimum width of
        hot-air weld shall be one and one-half inches (1-1/2").
        Lay the laps together and apply pressure to the welded seam to ensure full adhesion.
        Allow the seams to set fully, and probe the entire length for voids. Reseam voids immediately
        with a hot-air gun and roller. All hot-air welded seams/laps shall be tested daily with a probe for
        integrity, no variance.
