Joint Base Charleston - Appendix E - Page 10

No. Paragraph Description

1. 3.2.1.3. The COTR shall select three joists. At the midpoint of the joists, the distance from the bottom of the joist to the floor will be measured in inches and recorded as M1. A minimum of three pallets weighing 150 pounds per square foot shall be placed over the joists. After a continuous 4 hours, the distance from the midpoint of the joist to the floor will be measured in inches and recorded as M2. The deflection shall be calculated by using the following formula:

(M1 - M2) / (Span of joist in inches) =

Deflection

If the deflection is greater than (Span of joist in inches)/360 or any permanent deformation has occurred, the mezzanine shall fail the test.

2. 3.2.1.11. The operation of the pallet gate shall be tested. If the gates fails to operate properly or requires excessive force (greater than 40 pounds) to operate, the pallet gate fails this test.

3. 3.2.2.1. The lighting under the mezzanine shall be turned on. Test the lighting with a light meter 30 inches from the floor. If the lighting is not a minimum of 50 foot-candles then the system shall fail the test.

4.3. CERTIFICATIONS

The Contractor shall provide certification that the following requirements have been met. All certifications shall be provided in accordance with the Contract Data Requirements List.

No. Paragraph Certification

1. 3.2.1.1. All components of the mezzanine shall be designed to support a minimum capacity of 150 pounds per square foot.

Joint Base Charleston - Appendix E - Page 11

2. 3.2.3.3. All vertical members of the mezzanine shall have a minimum safety factor of 1.92 to 1 and all horizontal members shall have a minimum safety factor of 1.67 to 1.
