About this file

This document is a set of technical specifications for the design and construction of a Child Development Center at Fort Knox, Kentucky under solicitation W912QR24R0026. The specifications cover a wide range of requirements for the facility, including architectural, structural, mechanical, electrical, and plumbing systems. Key details include:

The project involves demolishing an existing pre-school and constructing a new standard design child development center to accommodate 338 pre-school children. The solicitation is being issued by the U.S. Army Corps of Engineers Louisville District for construction of the facility. The specifications provide detailed requirements for the wall panel assemblies, flashing and sheet metal, standing seam roofing, and other building components. Performance requirements are specified for factors such as wind load resistance, water infiltration, thermal movement, and structural integrity. Drawings, submittals, and quality control processes are also addressed in the specifications.

1.2 DEFINITIONS

Fabricated Wall Panel Assembly: Metal wall and liner panels, attachment system components, miscellaneous metal framing, thermal insulation, and accessories shop fabricated or field assembled for a complete weather-tight wall system.

1.3 DESCRIPTION OF FABRICATED WALL PANEL ASSEMBLY SYSTEM

Factory color finished, aluminum metal wall panel system with concealed fastening attachment. Panel profile must be smooth face.

1.3.1 Metal Wall Panel General Performance

Comply with performance requirements, conforming to AISI S100 , without failure due to defective manufacture, fabrication, installation, or other defects in construction. Wall panels and accessory components must conform to the following standards:

ASTM A1008/A1008M

ASTM A123/A123M

ASTM A36/A36M

ASTM A653/A653M

ASTM A463/A463M for aluminum coated steel sheet

ASTM A924/A924M for metallic coated steel sheet

ASTM C273/C273M

ASTM D522/D522M for applied coatings UL Bld Mat Dir

1.3.2 Structural Performance

Maximum calculated fiber stress must not exceed the allowable val ue in the AISI or AA manuals; a one third overstress for wind is allowed.

Midspan deflection under maximum design loads is limited to L/180.

Contract drawings show the design wind loads and the extent and general assembly details of the metal siding. Contractor must provide design for members and connections not shown on the drawings. Siding panels a nd accessories must be the products of the same manufacturer.

Provide metal wall panel assemblies complying with the load and stress requirements in accordance with ASTM E1592. Wind Load force due to wind action governs the design for panels.

Wall systems and attachments are to resist the wind loads as determ ined by UL 580 and ASCE 7-16 in the geographic area where the construction will

SECTION 07 42 63 Page 5 take place, in pounds per square foot. Submit five copies of wind load tests and seismic tests to the Contracting Officer.

Provide metal wall panel assembly for seismic conditions complying with the applicable requirements of AISC 341 .

1.3.3 Air Infiltration

Air leakage must conform to the limits through the wall assembly area when tested according to ASTM E283.

1.3.4 Water Penetration Under Static Pressure

No water penetration when tested according to ASTM E331.

1.3.5 Water Penetration Under Dynamic Pressure

No evidence of water leakage when tested according to AAMA 501.1 .

1.4 SUBMITTALS
