Section 05100<br />

Page 5<br />

unless specifically allowed by the Architect. Where used, short-slotted holes shall be oriented normal to the<br />

direction of load.<br />

B. Provide beveled washers for surfaces out of parallel more than 1:20.<br />

C. Provide bolts of sufficient length to extend entirely through nuts.<br />

D. Protect fasteners from dirt and moisture at job site. Only as many fasteners as are anticipated to be installed<br />

and tightened during a work shift shall be taken from protective storage. Fasteners not used shall be returned<br />

to protected storage at end of shift. Fasteners shall not be cleaned of lubricant that is present in as-delivered<br />

condition.<br />

E. Anchor bolts and erection bolts: tighten with a suitable wrench not less than 15 inches long. Tap bolt heads<br />

with a hammer while tightening.<br />

F. High Strength Bolts (typical, except as noted otherwise): install bolts in properly aligned holes, and tighten to<br />

snug tight condition. Snug tight condition is defined as the tightness that exists when all plies in a joint are in<br />

firm contact.<br />

G. Hand tighten and tack weld (nut-to-bolt shank) bolts required to be "finger-tight".<br />

H. Holes for anchor bolts in base plates may be oversized in accordance with AISC Specifications. Provide<br />

washers as indicated on Drawings.<br />

2.09. SHOP PAINTING<br />

A. Apply one coat of rust-inhibitive primer to exposed surfaces of structural steel members except: surfaces<br />

required to be field welded, to be encased in concrete, to be spray fireproofed, and top flanges of beams with<br />

shear connectors to support metal deck.<br />

B. Thoroughly clean surfaces to be painted of all loose mill scale, dirt, rust, and other foreign matter with steel<br />

scrapers, wire brushes, or sandblasting in accordance with SSPC SP-3. Remove oil and grease with solvents.<br />

C. Mix paint in accordance with manufacturer's recommendations, continuously stir during application, and do<br />

not add thinner after initial mixing.<br />

D. Apply paint in accordance with manufacturer's recommendations, thoroughly work over surfaces and into<br />

corners. Minimum dry thickness of coating shall be 2 mils.<br />

E. Repair damage to coating prior to delivery.<br />

2.010. FUSION WELDED ANCHORS<br />

A. Comply with AWS D1.1, Section 7.<br />

B. Clean surfaces to be welded of rust, oil, grease, paint and dirt. Remove mill scale by scraping or sandblasting.<br />

C. Weld headed studs with appropriate equipment properly adjusted for climactic conditions.<br />

D. Remove ceramic ferrules after welding.<br />

2.011. SOURCE QUALITY CONTROL<br />

A. Testing of Shear Studs:<br />

1. When temperature is below 32 degrees F, one stud in each 100 shall be tested.<br />

2. Minimum of 2 shear studs shall be tested at start of each production period in order to determine proper<br />

generator, control unit and stud welder setting. Studs shall be capable of being bent 45 degrees from<br />

vertical without weld failure. If, after welding, visual inspection reveals that sound weld or full 360<br />

degree fillet has not been obtained for a particular stud, stud shall be struck with hammer and bent 15<br />

degrees off perpendicular toward nearest end of beam. Studs failing this test shall be replaced.<br />

B. Pre-Erection Testing of High Strength Bolts<br />

1. Test at least three bolt, nut and washer assemblies from each lot of bolts supplied to job site.<br />

2. Test assemblies in a tension measuring device at site to verify that assemblies can develop tension listed in<br />

Table 4 of AISC Specification for Structural Joints.<br />

3. Bolt tension shall be developed by tightening of nut.<br />

C. Inspection of Structural Steel:<br />

1. Provide access to materials in fabrication and full cooperation to testing laboratory.<br />

2. Following testing services shall be performed:<br />

a. Check temporary bracing of steel frame.<br />

b. Check location and condition of anchor bolts.<br />

c. Check plumbness and tolerance of steel frame.<br />

d. Qualification of welders and welding techniques.<br />

e. Visually inspect erection bolts.<br />

f. Inspection of high-strength bolting:<br />
