1.3 BASIS OF DESIGN

The sizes and makeups of performance specified members provided herein and shown in the Construction Drawings are provided to show the design intent.

However, it is the Contractor's responsibility to meet and demonstrate compliance with all requirements within this specification.

1.4 DEFINITIONS

a. Blast Consultant: Blast engineer for the design team.

b. Conventional Requirements: All performance requirements defined by other disciplines for architectural and structural components that are not related to blast requirements. These may include, but are not limited to, gravity, wind, seismic, thermal, and air and water infiltration performance requirements.

c. Coordination: It is the General Contractor's responsibility to coordinate connection design information between different trades and sub-contractors.

SECTION 01 81 23 Page 1

d. Nominal Material Strength: The published minimum strength of a component. For example the Nominal Material Strength of A36 steel is 36,000psi.

e. Structurally Glazed Unit: A window or curtain wall unit where the glazing is adhered to the surrounding mullion/frame with a structural silicone bead.

1.5 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. Submittals with an "S" are for inclusion in the Sustainability Notebook, in conformance with Section 01 33 29 SUSTAINABILITY REPORTING. Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

SD-02 Shop Drawings

Facade Profiles; G

Submit shop drawings showing the proposed facade facade profiles that demonstrate compliance with the design intent. This applies to all blast resistant systems.

Anchorages; G

Submit shop drawings showing the proposed facade anchorages that demonstrate compliance with the design intent. This applies to all blast resistant systems.

PART 3 EXECUTION

3.1 GLAZING

Basis of Design:

a. The minimum glazing makeup shall be as follows: Glazing in exterior building elements shall consist of a minimum 1/4" nominal laminated glass. The laminated glass shall consist of two nominal 1/8" glass panes, bonded together with a minimum 0.030" PVB interlayer. For insulated glass units, use laminated glass for the innermost pane as a minimum.

b. Glazing bite: The glass unit connections to the glazed unit framing shall be fabricated, and installed to meet the criteria specified in this section within the limits and under the conditions indicated.

1. Minimum Glazing Bite Requirements:

a) Provide Minimum glazing bite in accordance with ASTM F2248.

3.2 EXTERIOR WINDOW AND CURTAIN WALL BLAST DESIGN CRITERIA

a. Anchorages and Connections:

1. Design responsibility: Design of window and curtain wall anchorages to the supporting structure (i.e. building structure, concrete masonry unit walls, etc.) is the responsibility of the Contractor. Connection details shown on the architectural and structural drawings are schematic only .

b. Anchorage/Connection Design:

1. Design anchorages and connections per the project applicable versions of AISC manuals for steel connections, Aluminum Design Manual for aluminum connections, ACI-318 or PCI manual for anchorage to concrete.

3.3 EXTERIOR DOORS

Applicability: All exterior hollow metal doors.

Performance Criteria: Design, fabricate, and install hollow metal doors to comply with the following:

a. Exterior doors shall swing outward and be a minimum 16GA hollow metal with a minimum 16GA fully welded hollow metal frame.

b. Provide doors that are tested to achieve the applicable door damage level category and glazing Hazard Rating in Table 2-1 in accordance with ASTM F2927. Unless included as part of the tested assembly, glazed skylights and transoms around doors must meet the requirements of Paragraph 3.1 of this section.
