[PART 3: EXECUTION]{.underline}

3.1 ERECTION/INSTALLATION

A. Erection

1\. Supporting members shall be completely in place before the laying of
deck units is undertaken.

2\. Laying and aligning of units shall be done so as to maintain the
required number of units shown on the shop drawings and to prevent
stretching or contracting of the sidelaps.

3\. End laps shall be a minimum of six inches and shall occur over
supports.

4\. Provide framing around openings in roof deck that are 12 inches or
more in dimension in either direction.

5\. The deck shall be installed with self-drilling, self-tapping
power-driven screws designed for this purpose.

B. Welds: When welded connections are requested in writing and approved
for use, the following shall apply:

1\. The average spacing of welds shall not exceed 6 inches oc at sheet
ends and endlaps or diaphragm edges, and 12 inches oc at intermediate
supports.

2\. Puddle welds shall be 1/2 inch minimum diameter fusion welds.

3\. Button punching for seam connections acceptable. Maximum spacing of
button punches to be 20 inches oc.

4\. Add additional welds (including seam welds) in addition to those
required by above where required by the shop drawings. Blow holes will
be cause for rejection of the damaged section of the roof.

5\. Welding sequence and procedure shall be coordinated with the placing
of units, and shall be shown on shop drawings and approved before
proceeding with the work.

6\. Metal fillers and closure pieces shall be welded.

7\. Clips, button punching, or welding shall be required to lock the
