1. Contractor is responsible for ensuring wall pat ches in existing rated walls are made using correct fire rated mater ial and methods to provide required rating.

1.8 INFECTION PREVENTION MEASURES

A. Implement the requirements of VAMC’s Constructio n Health and Safety

Team (CHST). See Attachment #1 – Construction Healt h and Safety Form at end of section. (CHST) Group may monitor dust in th e vicinity of the construction work and require the Contractor to tak e corrective action immediately if the safe levels are exceeded.

B. Establish and maintain a dust control program as part of the contractor’s infection preventive measures in accor dance with the guidelines provided by (CHST) Group. Prior to start of work, prepare a plan detailing project-specific dust protection mea sures, including periodic status reports, and submit to COR and (CHS T) Group for review for compliance with contract requirements in accord ance with Section 01

33 23, SHOP DRAWINGS, PRODUCT DATA AND SAMPLES.

1. All personnel involved in the construction or r enovation activity shall be educated and trained in infection preventi on measures established by the medical center.

C. Medical center Infection Control personnel shall monitor for airborne disease (e.g. aspergillosis) as appropriate during construction. A baseline of conditions may be established by the me dical center prior to the start of work and periodically during the co nstruction stage to determine impact of construction activities on indo or air quality. In addition:

1. The COR and VAMC Infection Control personnel sha ll review pressure differential monitoring documentation to v erify that pressure differentials in the construction zone and in the patient-care rooms are appropriate for their settin gs. The requirement for negative air pressure in the constr uction zone shall depend on the location and type of activity. Upon notification, the contractor shall implement correc tive measures to restore proper pressure differentials as needed.

2. In case of any problem, the medical center, alo ng with assistance from the contractor, shall conduct an environmental assessment to find and eliminate the source.

D. In general, following preventive measures shall be adopted during construction to keep down dust and prevent mold.

1. Dampen debris to keep down dust and provide tem porary construction partitions in existing structures wher e directed by

COR. Blank off ducts and diffusers to prevent circu lation of dust into occupied areas during construction.

2. Do not perform dust producing tasks within occu pied areas without the approval of the COR. For construction in any ar eas that will remain jointly occupied by the medical Center and C ontractor’s workers, the Contractor shall:

a. Provide dust proof one-hour fire-rated temporar y drywall construction barriers to completely separate constr uction from the operational areas of the hospital in order to contain dirt debris and dust. Barriers shall be sea led and made presentable on hospital occupied side. Install a self-closing rated door in a metal frame, commensurate w ith the partition, to allow worker access. Maintain negativ e air at all times. A fire retardant polystyrene, 6-mil thic k or greater plastic barrier meeting local fire codes ma y be used where dust control is the only hazard, and an agreement is reached with the COR and Medical Cente r.

b. HEPA filtration is required where the exhaust d ust may reenter the breathing zone. Contractor shall verify that construction exhaust to exterior is not reintroduce d to the medical center through intake vents, or building op enings.

Install HEPA (High Efficiency Particulate Accumulat or) filter vacuum system rated at 95% capture of 0.3 mi crons including pollen, mold spores and dust particles. I nsure continuous negative air pressures occurring within the work area. HEPA filters should have ASHRAE 85 or other p refilter to extend the useful life of the HEPA. Provide both primary and secondary filtrations units. Exhaust hoses shal l be heavy duty, flexible steel reinforced and exhausted so that dust is not reintroduced to the medical center.

900mm (24” x 36”), shall be used at all interior transitions from the construction area to occupied medical center area. These mats shall be changed as often a s required to maintain clean work areas directly outs ide construction area at all times.

d. Vacuum and wet mop all transition areas from co nstruction to the occupied medical center at the end of each w orkday.

Vacuum shall utilize HEPA filtration. Maintain surr ounding area frequently. Remove debris as they are created.

Transport these outside the construction area in co ntainers with tightly fitting lids.

e. The contractor shall not haul debris through pa tient-care areas without prior approval of the COR and the Med ical

Center. When, approved, debris shall be hauled in e nclosed dust proof containers or wrapped in plastic and sea led with duct tape. No sharp objects should be allowed to cu t through the plastic. Wipe down the exterior of the containers with a damp rag to remove dust. All equi pment, tools, material, etc. transported through occupied areas shall be made free from dust and moisture by vacuum ing and wipe down.

f. Using a HEPA vacuum, clean inside the barrier a nd vacuum ceiling tile prior to replacement. Any ceiling acce ss panels opened for investigation beyond sealed areas shall be sealed immediately when unattended.

g. There shall be no standing water during constru ction. This includes water in equipment drip pans and open cont ainers within the construction areas. All accidental spill s must be cleaned up and dried within 12 hours. Remove and dispose of porous materials that remain damp for more than 72 hours.

h. At completion, remove construction barriers and ceiling protection carefully, outside of normal work hours. Vacuum and clean all surfaces free of dust after the remov al.

E. Final Cleanup:
