ICRA Group may monitor dust in the vicinity of the construction work and require the Contractor to take 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 accordance with the guidelines provided by ICRA Group. Prior to start of work, prepare a plan detailing project-specific dust protection measures, including periodic status reports, and submit to Contracting Officer and Facility ICRA team

01 00 00 - 14 AM-01

for review for compliance with contract requirements in accordance with Section 01 33 23, SHOP DRAWINGS, PRODUCT DATA AND SAMPLES.

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 medical center prior to the start of work and periodically during the construction stage to determine impact of construction activities on indoor air quality. In addition:

1) The Contracting Officer and VAMC Infection Control personnel shall review pressure differential monitoring documentation to verify that pressure differentials in the construction zone and in the patient-care rooms are appropriate for their settings. The requirement for negative air pressure in the construction zone shall depend on the location and type of activity. Upon notification, the contractor shall implement corrective measures to restore proper pressure differentials as needed.

2) In case of any problem, the medical center, along 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 temporary construction partitions in existing structures where directed by VA Construction Inspector. Blank off ducts and diffusers to prevent circulation of dust into occupied areas during construction.

2) Do not perform dust producing tasks within occupied areas without the approval of the Contracting Officer. For construction in any areas that will remain jointly occupied by the medical Center and Contractor's workers, the Contractor shall:

(a) Provide dust proof temporary drywall construction barriers to completely separate construction from the operational areas of the hospital in order to contain dirt debris and dust. Barriers shall be sealed and made presentable on hospital occupied side. Install a self-closing door in a frame, commensurate with the partition, to allow worker access. Maintain negative air at all times. A fire retardant polystyrene, 6-mil thick or greater plastic barrier meeting local fire codes may be used where dust control is the only hazard, and an agreement is reached with the Contracting Officer and Medical Center.

(b) HEPA filtration is required where the exhaust dust may reenter the breathing zone. Contractor shall verify that construction exhaust to exterior is not reintroduced to the medical center through intake vents, or building openings. Install HEPA (High Efficiency Particulate Accumulator) filter vacuum system rated at 95% capture of 0.3 microns including pollen, mold spores and dust particles. Insure continuous negative air pressures occurring within the work area. HEPA filters should have ASHRAE 85 or other prefilter to extend the useful life of the HEPA. Provide both primary and secondary filtrations units. Exhaust hoses shall be heavy duty, flexible steel reinforced and exhausted so that dust is not reintroduced to the medical center. Filters shall be checked and replaced at regular intervals to maintain the integrity of the HEPA vacuum system.

(c) Adhesive Walk-off/Carpet Walk-off Mats, minimum 600mm x 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 as required to maintain clean work areas directly outside construction area at all times.

01 00 00 - 15 AM-01

(d) Vacuum and wet mop all transition areas from construction to the occupied medical center at the end of each workday. Vacuum shall utilize HEPA filtration. Maintain surrounding area frequently. Remove debris as they are created. Transport these outside the construction area in containers with tightly fitting lids.

(e) The contractor shall not haul debris through patient-care areas.

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

(g) There shall be no standing water during construction. This includes water in equipment drip pans and open containers within the construction areas. All accidental spills 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 removal.

e. Final Cleanup:

1) Upon completion of project, or as work progresses, remove all construction debris from above ceiling, vertical shafts and utility chases that have been part of the construction.

2) Perform HEPA vacuum cleaning of all surfaces in the construction area. This includes walls, ceilings, cabinets, furniture (built-in or free standing), partitions, flooring, etc.

3) All new air ducts shall be cleaned prior to final inspection.

1.12.7 Disposal, Retention and Recycling

A. Materials and equipment accruing from work removed and from demolition of buildings or structures, or parts thereof, shall be disposed of as follows:

1) Reserved items (such as desks and file cabinets) which are to remain property of the Government shall be protected in such a manner as to prevent damage which would be detrimental to re installation and reuse.

2) Items not reserved shall become property of the Contractor and be removed by Contractor from the Medical Center.

3) Contractors will make a reasonable effort to salvage or recycle all applicable waste generated during the course of the project. Alternatives to land-fill will be considered, materials appropriate for recycling or salvage will be separated and taken to a recycling facility. A report detailing the type and quantity of material recycled will be furnished to the Contracting Officer. All hazardous wastes shall be separated, stored, and disposed of according to local, state and federal regulations. Legible manifests will be provided to the Contracting Officer after disposal of hazardous waste. Any discharge into the city sewer system will require prior Contracting Officer approval, any spills into the storm drains will be reported immediately to the Contracting Officer with appropriate mitigation activity as needed. The Contractor shall have the

01 00 00 - 16 AM-01

responsibility of instructing all sub-contractors of this requirement.

1.12.8 Protection of Existing Vegetation, Structures, Equipemnt, Utilities and Improvements
