PART 3 EXECUTION

  3.1     CASEWORK INSTALLATION

          A.   Install plumb, level, true and aligned with no distortions. Shim as required, using concealed
               shims. Where casework abuts other finished work, scribe and apply filler strips for accurate
               fit. All fasteners shall be concealed. No exposed fasteners allowed.

          B.   Base Cabinets: Set cabinets straight, plumb, and level. Adjust sub-tops within 1/16" of a
               single plane. Fasten each individual cabinet to floor at toe space, with fasteners spaced 24"
               o.c. Bolt continuous cabinets together. Secure individual cabinets with not less than 2
               fasteners into floor, where they do not adjoin other cabinets.
               1.     Where required, assemble units into one integral unit with joints flush, tight, and

                                                                                          Southlake, Texas
2010-10

                     uniform. Align similar adjoining doors and drawers to a tolerance of 1/16".

          C.   Wall Cabinets: Securely fasten to solid supporting material, not plaster, lath, or wallboard.
               Anchor, adjust, and align wall cabinets as specified for base cabinets.
               1.    Reinforcement of stud walls to support wall-mounted cabinets will be done during wall
                     erection by trade involved, but responsibility for accurate location and sizing of
                     reinforcement is part of this work.

          D.   Adjust casework and hardware so that doors and drawers operate smoothly without warp or
               bind. Lubricate operating hardware as recommended by manufacturer.

  3.2     INSTALLATION OF TOPS

          A.   Field Jointing: Where practicable, make in same manner as factory jointing using dowels,
               splines, adhesives, and fasteners recommended by manufacturer. Locate field joints as
               shown on accepted shop drawings, factory prepared so there is no job site processing of top
               and edge surfaces.

          B.   Fastenings: Use concealed clamping devices for field joints, located within 6" of front, at back
               edges and at intervals not exceeding 24". Tighten in accordance with manufacturer's
               instructions to exert a constant, heavy clamping pressure at joints. Secure tops to cabinets
               with "Z"-type fasteners or equivalent, using 2 or more fasteners at each front, end, and back.

          C.   Workmanship: Abut top and edge surfaces in one true plane, with internal supports placed to
               prevent any deflection. Provide flush hairline joints in top units using clamping devices.
               1.    After installation, carefully dress joints smooth, remove any surface scratches, clean
                     and polish entire surface.
               2.    Provide holes and cutouts as required for mechanical and electrical service fixtures.
               3.    Provide scribe mouldings for closures at junctures of top, curb and splash with walls as
                     recommended by manufacturer for materials involved. Use permanently elastic
                     sealing compound recommended by manufacturer.

  3.3     INSTALLATION OF ACCESSORIES

          A.   Install in a precise manner in accordance with manufacturer's directions. Turn screws to a
               flat seat; do not drive. Adjust moving parts to operate freely without excessive bind.

  3.4     CLEANING AND PROTECTION:

          A.   Repair or remove and replace defective work as directed upon completion of installation.

          B.   Clean shop-finished surfaces, touch-up as required, and remove or refinish damaged or
               soiled areas, as acceptable to Architect.

          C.   Protection: Advise Contractor of procedures and precautions for protection of materials and
               installed plastic laminate faced casework from damage by work of other trades.
