SECTION 052100 - STEEL JOIST FRAMING

In addition to general MasterSpec instructions for coordinating Drawings with Specifications, Drawings should indicate the following information related to this Section:

• Locations and extent of steel joist work. Show steel joist types and sizes using Steel Joist Institute (SJI) standard markings.
• Locations and extent of special joists and joist substitutes.
• Load diagrams for special joists. Indicate design loads including live, dead, and lateral loads; loading combinations; and magnitudes and locations of concentrated loads.
• Joist end arrangements. Indicate whether underslung, underslung with bottom-chord extensions, or square ended.
• Details of bearing plates and anchorages into supporting concrete or masonry construction.
• Floor and roof openings.
• Joist headers for K-series joists if applicable.
• Bridging details.
• Deflection limitations.
• Camber requirements if departing from SJI's Standard Specifications, Load Tables and Weight Tables for Steel Joists and Joist Girders.
• Roof-joist top-chord configuration and pitch.
• Roof-joist slope requirements.
• Locations, details, and designations of welded connections. Indicate sizes and number of welds.
• Locations, details, and designations of bolted connections. Indicate diameter and number of bolts. Indicate bolt material and quality if different bolt types are required.
• Sizes and spacing of holes in chords for securing wood nailers and other construction.
• Locations, extent, and details of construction if joists form part of a fire-resistance-rated assembly. Coordinate special requirements for sizes of components and bridging with UL or ITS design assemblies.
• Details of joist cantilevers, top-chord extensions, and extended ends.
• Locations of ceiling extensions.
• Locations and details of sloped end bearings.
