C-13 Sheet Metal Contractor (2023-11-01)

The third edition of the HVAC Duct Construction Standards – Metal and Flexible is intended primarily for commercial and institutional duct construction. This American National Standard contains tables and details for constructing ductwork for ½" to 10" wg positive and negative pressures. This edition improves upon the second edition with expanded pressure class tables, separate tables for TDC/TDF construction and expanded tables for round duct construction including 6" wg positive and negative pressure and sizes up to 96". New in this edition is an engineering and design chapter to provide additional information to design professionals, double-wall construction details, new casing construction details and additional accessory items. The standard is applicable for construction using uncoated steel, galvanized and stainless steels and a limited range of aluminum ducts. This standard has been adopted in the ICC International Mechanical Code.

Sheet Metal blends basic principles with contemporary tools and technology. Now including workbook questions, this edition is concisely written, with large, two-color illustrations and updated photography to emphasize key points.

The Architectural Sheet Metal Manual is the most comprehensive set of resources recommended for practices available for proper design and installation of custom-fabricated architectural sheet metal including roof drainage system design for scuppers, gutters and downspouts.

2018 IBC Turbo Tabs consist of clear plastic self-adhesive tabs that have key sections of the 2018 International Building Code printed on them in an easy-to-read format. Can be used with either the 2018 International Building Code or the 2018 IBC Code and Commentary.

The scope of the International Building Code® (IBC®) includes all buildings except detached one- and two-family dwellings and townhouses up to three stories. For the most current adoptions details go to International Code Adoptions The 2018 IBC contains many important changes such as:Accessory storage spaces of any size are now permitted to be classified as part of the occupancy to which they are accessory. New code sections have been introduced addressing medical gas systems and higher education laboratories. Use of fire walls to create separate buildings is now limited to only the determination of permissible types of construction based on allowable building area and height. Where an elevator hoistway door opens into a fire-resistance-rated corridor, the opening must be protected in a manner to address smoke intrusion into the hoistway. The occupant load factor for business uses has been revised to one occupant per 150 square feet. Live loads on decks and balconies increase the deck live load to one and one-half times the live load of the area served. The minimum lateral load that fire walls are required to resist is five pounds per square foot. Wind speed maps updated, including maps for the state of Hawaii. Terminology describing wind speeds has changed again with ultimate design wind speeds now called basic design wind speeds. Site soil coefficients now correspond to the newest generation of ground motion attenuation equations (seismic values). Five-foot tall wood trusses requiring permanent bracing must have a periodic special inspection to verify that the required bracing has been installed. New alternative fastener schedule for construction of mechanically laminated decking is added giving equivalent power-driven fasteners for the 20-penny nail. Solid sawn lumber header and girder spans for the exterior bearing walls reduce span lengths to allow #2 Southern Pine design values.

Additionally, select 1910 regulations relevant to construction industries are included. The book highlights regulation changes between releases and provides easy-to-access OSHA interpretations, aiding in clarity and reference. Essential documents such as OSHA Form 300 and the Cancer Policy are incorporated. In-Cite Referencing to applicable 1910 regulations is provided for further context. Lastly, the book outlines the Most Frequently Cited Standards preceding relevant Subparts, enhancing its utility as a comprehensive safety resource.

The 2018 edition of the Uniform Mechanical Code (UMC©) represents the most current approaches in the mechanical field. It is the sixth edition developed under the ANSI Consensus process is designated as an American National Standards by the American National Standards Institute (ANSI). The 2018 edition of the UMC reached a major milestone as it addresses specific provisions for low flammability refrigerants such as A2L and B2L; which makes it one of the first codes in the industry to address specific provisions for these low Global Warming Potential (GWP) refrigerants. Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, labor, manufacturers, research/standards/ testing laboratories, special experts and users.
