ANCHORAGE FEDERAL BUILDING DUST CONTROL SPECIFICATION

Indoor Air Quality Control Requirements

Part 1 – General

1.1 SECTION INCLUDES

A. 1.03 Dust Control

1.2 DESCRIPTION OF REQUIREMENTS

A. Specific minimum administrative and procedural actions are specified in this section. These requirements have been included for specific purposes as indicated.

B. A written plan outlining the contractor’s methods of meeting the Dust Control specification must be submitted to GSA for approval. The plan shall include, but not be limited to, construction barrier locations, exit path routing, temporary signage design and locations, proposed materials, negative air routing, and proposed cleaning equipment.

1.3 DUST CONTROL

A. BARRIERS

1. The contractor shall provide appropriate barriers to isolate the construction area from occupied areas. Barriers must enclose entire work area to completely isolate it from all surrounding areas. The barriers shall be constructed:

a. To be tightly sealed from wall to wall and floor to structure above. This includes areas above suspended ceilings, unless ceilings are not to be disturbed, in which case, seal will occur at ceiling level.

b. Out of the following materials:

1. For projects with little anticipated noise and no hot work, 6-mil fire-retardant (Rexam StarTex or approved equal) visqueen with zipper openings. Use appropriate mini-enclosure for all ceiling work outside of contained workspace.

2. Elevator openings, if not for a dedicated construction elevator, must be sealed air tight to the work area.

3. All work area entrances must have tacky mats present at all times. Mats must be clean, intact and maintained on a constant basis.

4. Adjacent floor areas directly outside the work area must be vacuumed or wet mopped at appropriate intervals to eliminate tracking and dust migration.

Contractor to provide vacuum cleaners and all cleaning equipment.

5. Prior to removal of any barriers, all debris must be removed, the work area wet mopped, vacuumed, and all surfaces wiped down.

6. All vacuums used for final cleaning of the work area must be equipped with HEPA filtration.

C. AIR DISTRIBUTION

1. The contractor shall provide all necessary equipment, including appropriate negative air machines and temporary ductwork to maintain a negative air pressure relationship, for all areas under construction or contained within the

ANCHORAGE FEDERAL BUILDING DUST CONTROL SPECIFICATION

construction barriers, to surrounding areas. Unless exempted by the GSA Project Manager and Contracting Officer in writing negative pressurization of the workspace is required at all times. Or control dust at the source when the area is not occupied.

a. Work area ventilation must be 100% exhausted to the exterior of the building unless provided written permission by owner to tie into building ventilation exhaust.

b. All negative air machines must have filtration in place. Pre-filters must be maintained to prevent airflow restriction and dust accumulation.

c. Discharge hoses, vented to an approved location, must be in place and intact at all times.

d. Penetrations or openings to barrier enclosing the negative pressure area must be tightly sealed at the end of each day.

2. Supply and exhaust air grills serving the building HVAC systems must be covered and sealed to prevent airflow at all times.

1.4 MATERIALS AND MATERIAL HANDLING

A. Selection of Materials

1. Prior to start of construction, contractor must submit Material Safety Data

Sheets on all paints, glues, mastics, epoxies, adhesives, cleaning products, etc. prior to start of construction for review by the GSA Project Manager.

2. All dirty materials including new materials, debris, and tools must be covered or wrapped when transported through the building.

3. Debris removal must occur in an exterior chute or through approved routes and only at specified times. After each period of debris removal, the traffic and material corridor shall be cleaned and wet mopped from entrance to work area to disposal area as necessary. Conveyances used for debris removal must be clean and covered.

4. At the end of each workday, work area must have all debris removed and floors cleaned.

5. Any material capable of absorbing moisture must be fully dried within 48 hours of becoming wet. If material, either new or existing, inside or out of the work area, becomes wet as a result of the contractors actions and is unable to be dried to an “as-new” condition within 48 hours, the contractor shall remove the material within the same 48 hour period. Materials removed from the work area for this reason must be replaced with new material at contractor expense.
