Work.

D. Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 PREPARATION

A. Provide temporary shores, guys, braces, and other support during erection to keep structural framing secure, plumb, and in alignment against temporary construction loads and loads equal to intensity to design loads. Remove temporary supports when permanent structural framing, connections, and bracing are in place unless otherwise indicated.

3.3 ERECTION OF STRUCTURAL TOWER SYSTEMS

A. Erect tower system according to manufacturer’s written erection instructions and erection drawings.

B. Do not field cut, drill, or alter structural members without written approval from tower system manufacturer’s professional engineer.

C. Set structural framing accurately in locations and to elevations indicated, according to AISC specifications referenced in this Section. Maintain structural stability of frame during erection.
