HOLLOW METAL FRAMES 23

Provide metal frames for doors, transoms, sidelights, borrowed lights, and other openings of types and styles as 25 shown on the Drawings and Schedules. Conceal fastenings, unless otherwise indicated. 26 Fabricate frames and associated members from 14-gauge (hot-dipped galvanized at exterior frames), cold-rolled 27 steel. 28 Frame corners for the three-sided door frames shall be die-mitered with frame face continuously welded and 30 ground smooth. Continuously back weld soffit and rabbets. Frame corners for transom, sidelight, and borrowed 31 light frames shall be saw-mitered or butt joint. Intermediate rail connections shall be coped and let into adjacent 32 members and all corners and connections shall be face welded and ground smooth. 33 Prepare stops to receive three door silencers on strike jambs of frames on single-leaf doors and two silencers on 35 heads of frames on double-leaf doors. Silencers shall be type GJ64 manufactured by Glynn Johnson. Silencers 36 shall not be omitted at doors scheduled to receive sound strips or weatherstripping. Silencers shall be furnished 37 under Section 08700. 38 Stops shall be 5/8-inch high unless noted otherwise on the Drawings or required to achieve specified fire ratings. 40 Jamb anchors shall be adjustable, 16-gauge corrugated steel, permanently fastened to the frame for setting into 42 masonry partitions, or standard steel stud anchors for metal stud/gypsum board partitions. Each jamb shall be 43 anchored to the floor with an adjustable base anchor. Other types of anchors shall be provided when required for 44 other conditions. Provide a minimum of three anchors per jamb for frames up to 90 inches high and four anchors 45 per jamb for frames over 90 inches high. 46

FABRICATION 48

C. EXECUTION 32

INSPECTION 34

Examine substrate and conditions under which metal frames are to be installed. Do not proceed with work until 36 unsatisfactory conditions have been corrected. 37

INSTALLATION 39

Comply with provisions of SDI-105 "Recommended Erection Instructions for Steel Frames," unless otherwise 41 indicated. Place frames prior to construction of enclosing walls and ceilings. After wall construction is completed, 42 remove temporary braces, and spreaders, leaving surfaces smooth and undamaged. 43 At new sills and thresholds installed on existing floor materials, level existing materials with grout as required to 45 make proper substrate for installation of new sill or threshold. 46 Install frames accurately in position, plumbed and aligned to Door and Hardware Institute standards, and braced 48 securely until permanent anchors are set. Anchor frames securely to floor and at jambs. Furnish necessary clips, 49 fastenings and anchorages, and conceal unless otherwise noted. Weld all field joints, grind smooth, and fill with 50 body putty to completely conceal seams and to form a smooth, unbroken finish surface. 51 Spot grout at all jambs of frames set into metal stud construction; this work is included under Section 09250. 52 Where frames are anchored with bolts, bolts shall be countersunk, and surfaces shall be made smooth with putty. 54 At the Contractor’s option, at conditions where new frames are to be installed in existing concrete or masonry 55 walls, frame jambs and heads may be installed using the following method: 56

- Grout new frame full prior to installation in wall 57

- Install frame in opening, anchoring with countersunk anchors through frame face, and body putty over 58 anchors 59

112-006 08100-4

- Tuck point (with grout) the frame perimeter between frame face and wall construction, holding grout back 1 1” from frame faces for caulk (caulk under Section 07900) 2

Install fire-rated frames in accordance with NFPA Standard No. 80. 4

ADJUST AND CLEAN 6

Immediately after erection, sand smooth any rusted or damaged areas of prime coat and apply touch-up of 8 compatible air-drying primer, paying particular attention to bottom of frames at the floor line. 9 Check and readjust operating finish hardware items, leaving metal doors and frames undamaged and in complete 11 and proper operating condition. 12
