3.2 SPECIFIC PERFORMANCE REQUIREMENTS

A. Dust Protection for Items: Where required for the proper protection of Items, follow the guidelines set forth below. Protect each Item against dust and the resultant deterioration and damage.

1. Draw polyethylene dust barriers tight and anchor on all sides. Where required, protect barrier to prevent contact with Item. Stretch polyethylene tautly, fold under itself at the edges, and anchor properly using duct tape plus ½’ staples or wood slate and drywall screws. Use tape to seal the enclosure, not to create it.

2. Submit the shop drawings and manufacturer’s technical information for to use. Drawings are to depict the Contractor’ proposed methods of protecting The Items from dust, dirt, and impact.

3. Venting: where venting is required in barriers to maintain temperature and humidity, provide filtered vents of the size and location to permit the circulation of ambient building air.

4. Adhesive Tapes: Seal dust barrier and drape seams against dust and moisture with appropriate plastic adhesive tapes that are moisture resistant and dust tight. Under no circumstance shall the Contractor apply tape directly to the item.

5. Buffer: Where dust protection is applied directly to an Item and the dust membrane comes in contact with metal, wood, painted, or cloth surfaces or any surface affected by moisture, apply a buffer between the surface and the dust barrier. This buffer shall be lightweight, breathable, non-abrasive, and chemically inert covering – DuPont’s Nomex or approved equal.

B. Moisture Protection for Items: Where required for proper protection of Items, provide polyethylene barrier similar to Dust barrier specified above.

1. Examine spaces for drip pans or other areas that exhibit leaking, and take precautions against spilling water in Items.

2. While piping will be drained prior to capping and removal, residual water may remain in pipes or other devices. Take care that water does not drip on Items.

3. Remove any water that spills during system or ceiling demolition, and dry surfaces.

C. Temperature and Humidity Protection for Items: Protect each Item against changes in humidity and against condensation, and the resultant deterioration and damage.

1. Maintain normal museum temperature and humidity levels during construction.

4. Do not allow silica gel or the container to come into direct contact with the Item.

5. Periodically inspect containment and dehumidification chemical. Replace as needed.

D. Impact Protection for Items: Where required for the proper protection of Items, protect each Item against impact and the resultant damage.

1. See Prototypical Details on Drawings for recommended approach to protection of Items.

2. Rigid Protection: Provide rigid protection on horizontal surfaces where items are impacted by work directly above, on vertical surfaces of glass-front cabinets, and any other circumstances that require enhanced protection.

d. Venting: Provide venting high and low for natural convection. Size and place vents to allow air flow through case. Provide filters at vents for dust.

e. Buffer: Separate Item from Rigid Protection with rosin paper, polyethylene, neoprene, or other archival sheeting material.

3. Soft Impact Protection: Provide soft protection where rigid performance is not required, or for irregularly-shaped objects not requiring rigid protection.

a. Performance: Design soft protection to protect the specific Item against impact or contact. The horizontal protection must stop a .5 kilogram with a 25 mm diameter contact surface dropped from 3 meters.

b. Prefabrication: Prefabricate soft protection off site to the greatest extent possible.

c. Mobility: Protection shall be easily placed around and over the Item.
