SECTION 23 99 00DESIGN REQUIREMENTSDIVISION 23 (HVAC) PREFERRED MANUFACTURERSGENERAL INFORMATION1.1 Manufacturers on this list fall into two categories:a. Preferred Manufacturers: indicated in highlighted text, these products are pre-approved.b. Conditional Approval: Manufacturers approved for certain projects. Contact Columbia UniversityFacilities (CUF) for approval to use on new projects.1.2 This list is intended to cover major equipment vendors listed in the Specification sections. Often, ancillaryvendors used to construct the equipment are listed within the specification sections (e.g. pipe and ductsealants, firestopping, etc.). This list does not absolve the Consultant from reading and complying with therequirements set forth in the Specification Sections and sound engineering practices.1.3 Corrections/Substitutions: If there are errors in model numbers or manufacturers listed, or if a model is nolonger available, notify Columbia University Facilities in writing for a clarification. A response regarding theCorrection or Substitution will be provided.DESIGN REQUIREMENTS23 05 16 – EXPANSION JOINTS AND LOOPS1. Expansion Joints - Bellow Type (Packless)a. Badger Company Series 300b.
