PART 3 EXECUTION

3.1 INTERIOR DUST CONTROL - INFECTION CONTROL

3.1.1 HVAC SYSTEM ISOLATION

3.1.1.1 During Construction Project

Remove or isolate existing HVAC system(s) in area where the work is being done to prevent contamination of the ventilation system(s)system. Return air pathways passing out the construction space will be blocked. Stubbed ventilation ducts will be sealed to include the encasement of any exterior duct insulation to prevent the entrainment of contaminants that may later become airborne.

Maintain negative air pressure within enclosed work site with respect to adjacent occupied spaces by utilizing HEPA equipped air filtration units.

If the work site is not enclosed, coordinate with the Medical Facilities Manager to ensure the adjacent occupied spaces are at a higher pressure than the work site.

3.1.1.2 Upon Completion of Work

Install temporary startup and testing ventilation filters specified for normal system operation before the initial start and testing of HVAC systems(s). Clean ducts using a HEPA filtered vacuum and wipe down the interior of all ducts with a wet disinfectant approved by the Infection Control Department. If the startup and commission of HVAC system(s) are done before the final cleaning of work area, flush the HVAC system(s) for 24 hours by operating the system at the maximum allowable static pressure once the work area has received the final cleaning. Before turn over of the project to Medical Facilities Management replace temporary startup filters with new filters.

Stubbed duct connections will *not* be reconnected to an active HVAC system until after the final clean up of the construction area - no exceptions.

The HVAC system will be deactivated during duct reconnections and the inside of the duct at the reconnection shall be vacuumed and wiped with an approved disinfectant.

3.1.2 WORK AREA ISOLATION

3.1.2.1 During Construction Work

Seal work area by installing barriers (drywall, plywood, or plastic) between occupied/active health care spaces and work area. If plastic barriers are used they must be of the appropriate fire rating for the adjoining health care operation.

If entrances to the work area are required thru active health care spaces, then double sealing doorways will be used for plastic door barriers. If frame doors are used within the barriers, the doors shall be self closing.

Walk off mats shall be used at all entrances.

Transport work materials and construction waste in tightly covered containers when moving thru active areas. Container or cart coverings will be tapes on all sides, or a closed solid lid will be used. Contractor shall clean interior pathways to and from the work area each day.

3.1.2.2 Upon Completion of Work

The Contractor shall clean in accordance with Section 01 78 02.00 10 CLOSEOUT SUBMITTALS, paragraph "FINAL CLEANING." The Contractor is responsible for coordination the the MEDDAC Environmental Services Department for health care standard cleaning of the space. Do not remove barriers from work area until the completed project is inspected by the Safety Department and Infection Control Department.

Remove Barrier materials carefully to minimize spreading dirt and debris that has accumulated during construction.

3.1 EXTERIOR DUST CONTROL

Control techniques for fugitive dust sources shall involve watering, chemical treatment, light bituminous treatment, reduction of surface wind speed with wind breaks or source enclosures, or similar methods. The methods utilized shall be cost effective and appropriate for the size and scope of the fugitive dust source.
