PART 1 - GENERAL

1.01RELATED DOCUMENTS

  1. Drawings and general provisions of the Contract, including General and Supplementary Conditions and Division 01 Specification Sections, apply to this Section.
  2. Specifications throughout all Divisions of the Project Manual are directly applicable to this Section, and this Section is directly applicable to them.

1.02REFERENCE STANDARDS

  1. The latest published edition of a reference shall be applicable to this Project unless identified by a specific edition date.
  2. All reference amendments adopted prior to the effective date of this Contract shall be applicable to this Project.
  3. All materials, installation and workmanship shall comply with the applicable federal, state, and local requirements, and conform to codes and ordinances of the authorities having jurisdiction.

1.03QUALITY ASSURANCE

[RETAIN THE NEXT PARAGRAPH. QUALIFIED INSTALLERS ARE USUALLY NEEDED TO ASSURE SUCCESSFUL INSTALLATION.]

[ARCHITECT/ENGINEER MUST DELETE EVERYTHING IN BLUE AND IN BRACKETS BEFORE PUBLISHING.]

  1. Installer Qualifications: Engage an experienced Installer who has completed installations of all glass entrances similar in design and extent to those required for the Project and whose work has resulted in construction with a record of successful in- service performance.

[RETAIN THE NEXT PARAGRAPH FOR PROJECTS WHERE USE OF THE MANUFACTURER'S STOCK COMPONENTS IS ACCEPTABLE.]

  1. Manufacturer's Qualifications: Provide all glass entrances produced by a firm experienced in manufacturing entrance systems that are similar to those indicated for this Project and that have a record of successful in- service performance.
  2. Single Source Responsibility: Obtain all glass entrance systems from one (1) source from a single manufacturer.

[THE PARAGRAPH BELOW IS INTENDED TO ALLOW COMPETITION BETWEEN MANUFACTURERS OFFERING PRODUCTS THAT ARE SIMILAR WITHOUT HAVING TO DEVELOP CUSTOM COMPONENTS, AND TO ALLOW ARCHITECTS TO BASE THEIR DESIGN ON PRODUCTS FROM ONE OF THESE MANUFACTURERS.]

  1. Design Criteria: The Drawings indicate the size, profile, and dimensional requirements of the all glass entrance system required and are based on the specific types and models indicated. All glass entrances by other manufacturers may be considered provided deviations in dimensions and profiles are minor and do not change the design concept as judged by the Architect. The burden of proof of equality is on the proposer.
  2. Safety Glass Standard: Provide tempered glass components that comply with ANSI Z97.1 and testing requirements of CPSC 16 CRF Part 1201 II.
  1. Accessible All Glass Entrance Doors: Comply with applicable provisions in the Texas Department of Licensing and Regulation, Texas Accessibility Standards of the Architectural Barriers Act, Article 9102, Texas Civil Statutes, as well as the Americans with Disabilities Act, 28 CFR Part 35 Nondiscrimination on the Basis of Disability in State and Local Government Services.
