Shop Priming: Apply shop primer to comply with SSPC-PA 1, "Paint Application <br />Specification No. 1: Shop, Field, and Maintenance Painting of Steel," for shop <br />painting. <br />1. Stripe paint corners, crevices, bolts, welds, and sharp edges. <br />PART 3 - EXECUTION <br />3.1 INSTALLATION, GENERAL <br />A. Cutting, Fitting, and Placement: Perform cutting, drilling, and fitting required for <br />installing metal fabrications. Set metal fabrications accurately in location, <br />alignment, and elevation; with edges and surfaces level, plumb, true, and free of <br />rack; and measured from established lines and levels. <br />B. Fit exposed connections accurately together to form hairline joints. Weld <br />connections that are not to be left as exposed joints but cannot be shop welded <br />because of shipping size limitations. Do not weld, cut, or abrade surfaces of exterior <br />units that have been hot-dip galvanized after fabrication and are for bolted or <br />screwed field connections. <br />C. Field Welding: Comply with the following requirements: <br />1. Use materials and methods that minimize distortion and develop strength and <br />corrosion resistance of base metals. <br />2. Obtain fusion without undercut or overlap. <br />3. Remove welding flux immediately. <br />4. At exposed connections, finish exposed welds and surfaces smooth and <br />blended so no roughness shows after finishing and contour of welded surface <br />matches that of adjacent surface. <br />D. Fastening to In-Place Construction: Provide anchorage devices and fasteners where <br />metal fabrications are required to be fastened to in-place construction. Provide <br />threaded fasteners for use with concrete and masonry inserts, toggle bolts, through <br />bolts, lag screws, wood screws, and other connectors. <br />E. Provide temporary bracing or anchors in formwork for items that are to be built into <br />concrete, masonry, or similar construction. <br />3.2 INSTALLING MISCELLANEOUS FRAMING AND SUPPORTS <br />A. General: Install framing and supports to comply with requirements of items being <br />supported, including manufacturers' written instructions and requirements indicated <br />on Shop Drawings. <br />B. Anchor supports for ceiling hung toilet partitions, operable partitions, overhead <br />doors, and overhead grilles securely to, and rigidly brace from, building structure.
