About this file
This is a specification section for hangers and supports for plumbing piping and equipment related to Project 25-388, a HVAC and Lighting Upgrade project. The specification outlines the requirements for metal channel framing systems, nonpenetrating rooftop supports, post-installed concrete and masonry anchors, and thermal insulated pipe supports. The section includes reference to related metal fabrication work and establishes compliance standards including ASTM specifications for zinc coating and hot-dip galvanizing, MSS SP-58 standards for pipe hangers and supports, and UL 723 standards for surface burning characteristics. Contractors must submit product data sheets for manufactured components and shop drawings for any fabricated hangers where substitutions from standard materials or methods are proposed. Delivery, storage, and handling must comply with manufacturer instructions.
Installation requirements mandate compliance with manufacturer instructions and verification of field measurements and mounting surfaces prior to work commencement. All support materials must utilize zinc-plated or hot-dip galvanized steel per ASTM specifications, with electroplated components meeting ASTM B633 standards. Materials must be fully compatible with exposed piping and suitable for the installation environment. Field quality control includes inspection of all components for damage and defects, with repair of galvanized finish cuts and abrasions using zinc-rich paint and replacement of any components showing corrosion signs. The specification does not include pricing information, award dates, contract term details, or specific quantities for the hangers and supports.
