b. Repair any damaged flooring from the construction/demolition process.
c. Repair walls/doors/trim of any damage in the construction/demolition process.
5. Equipment
a. Any heavy equipment or rigging shall be provided by the contractor or equipment vendor
6. Fire Protection During Construction
a. Coordinate with the project Contracting Officer Representative (COR) prior to and throughout the construction period.
b. Coordinate with the project Contracting Officer Representative (COR) prior to and throughout the construction period.
c. Fire protection during construction shall comply with VA Master Construction Specification (VAMCS) 01 00 00, General Requirements. (Note: VAMCS 01 00 00, General Requirements, addresses NFPA 241, Joint Commission Interim Life Safety Measures, and Hot Work Permits. This specification section was formerly section 01010.)
d. Separate all occupied areas from demolition, renovation, or construction activities by temporary smoke-tight construction partitions of gypsum board or other approved non-combustible or limited-combustible material. Partitions shall be full height, extending through suspended/hard ceilings to the floor slab or roof deck above and shall be one-hour fire rated, unless sprinklers are installed and are operational on both sides of the temporary partition whereupon the partition may be permitted to terminate at the ceiling in accordance with NFPA 241. Where the ceiling on one side of the temporary construction barrier has been removed, the temporary wall would need to go to the deck above. This requirement is due to the inherently greater potential for fire or hazardous materials incidents associated with the combustibles and operations of demolition/construction. This risk is made worse by the likelihood of compromised fire protection systems and fire/smoke resistant construction. This does not obviate the need to provide other protective measures to contain dust and debris as specified by VAMCS 01 00 00 section 1.8(D)(2). Sprinklers are considered to be operational when they are installed in accordance with NFPA 13 (spacing, protection, distance from the ceiling, etc.) and there is a sufficient automatic water supply. If the ceiling was removed and the sprinklers remain at the original ceiling level, they would likely not be considered operational.
e. Provide dust proof one-hour / fire-rated drywall construction barriers to separate construction from the operational areas of the clinic in order to contain dirt debris and dust. Barriers shall be sealed and made presentable on clinic occupied side. Install a self-closing rated door in a metal frame, commensurate with the partition, to allow worker access. Always maintain negative air. 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 COR and Safety Office.
f. Phase construction as necessary to ensure that obstruction of exits is minimized or avoided. If exits are obstructed during construction, provide alternate exit routes during each phase of construction, and identify the alternate routes on the construction drawings.
g. Minimize or avoid disruptions to fire alarm and sprinkler systems. Delineate phasing of construction to ensure that installations of new systems are expedited, and where possible, maintain existing systems in service until the replacement system is operational. If fire protection systems are to be disrupted, ensure procedures are incorporated to maintain equivalent levels of fire protection and provide 5 calendar days formal written notification to COR and Safety Office before fire alarm systems are taken out of service.
7. Infection Control- During Construction
a. Implement the requirements of VAMC’s Infection Control Risk Assessment (ICRA) team. 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. The contractor is responsible for notifying/educating all personnel involved in the construction or renovation process in infection prevention measures established by the medical center and as noted on the ICRA Permit Form which will be provided at the Preconstruction Meeting.
c. Isolate HVAC system in area where work is to be done to prevent the contamination of the air duct system.
d. Complete all critical barriers i.e. (sheetrock, plastic, etc. to seal area from non-work area or implement control cube method (cart with plastic covering and sealed connection to work site with HEPA vacuum - prior to vacuuming and prior to exit) before construction begins.
e. HEPA filtration is required where the exhaust dust may re-enter the breathing zone.
f. Contractor shall verify that construction exhaust that is released to the exterior of the building is not reintroduced and circulated back to the medical center via intake vents, or other building openings.
g. Negative air pressure must be maintained within workspace throughout the construction project. 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 pre-filter 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 and circulated back through the medical center. HEPA filters must be routinely monitored and replaced once filter become visibly dirty or is no longer effective.
h. Seal all holes, pipes, conduits, penetrations, or punctures within the envelope of the work area in an appropriate manner. The selected method of sealing must maintain the construction areas required fire/smoke rating.
i. The Contractor shall construct an “ante-room” and require all personnel to pass through this room so they can be vacuumed using an HEPA vacuum cleaner before leaving the worksite or they can wear cloth or paper coveralls that are to be removed each time they leave the worksite. Keep area adjacent to the “ante-room” mopped and clean as required due to heavy worksite traffic.
j. During demolition, any dust producing work, and/or work in the ceiling, disposable shoes or shoe covers must be worn. This footwear shall be removed in the “ante-room” whenever the worker exits the work site.
k. Do not remove any construction barriers from the work area until the area is thoroughly cleaned, and the project is signed off as complete by the COR.
l. Provide and install adhesive dust “sticky” walk-off mats at each entrance/exit of construction area. These mats shall be a minimum 600mm x 900mm (24” x 36”). Replace walk-off mats as often as required while maintaining clean work areas directly outside of the construction areas.
m. Vacuum and wet mop all transition areas between the construction area and the occupied medical center at the end of each workday. The Vacuum shall utilize a HEPA filter. Maintain the surrounding area by frequently removing debris. Transport the debris to a location outside of the construction area. Utilize containers with tightly fitting lids and dispose of them dumpsters that are provided by the contractor.
n. There shall be no standing water created and present on the worksite during construction. This includes water located in equipment drip pans and open containers within the construction areas. All accidental spills must be cleaned up and dried within 30 minutes. Remove and dispose of porous materials that remain damp for more than 24 hours.
8. Infection Control– Upon Project Completion
a. During demobilization, remove barrier material carefully to minimize the spreading of dirt and debris that was generated during construction.
b. Transport construction waste in tightly covered containers.
c. Cover transport receptacles or carts with a solid lid. Tape any covering that is not covered with a solid lid.
d. Clean and mop areas with disinfectant or as approved by the COR.
e. Remove the isolation barriers that were placed upon the HVAC systems located within the areas where construction work was performed.
f. Vacuum using a HEPA filter and wipe clean all surfaces in the construction area. This includes walls, ceilings, cabinets, casework, furniture (built-in or free standing), partitions, flooring, etc.
9. Installation Time All work shall be completed within 180-calendar days after “Notice to Proceed” is received by the Contractor. To not/minimize impact patient care, the COR and contractor should coordinate schedule.
10. Special Bid Considerations by the Contractor It is the responsibility of the Contractor and all involved sub-contractors to visit the site and field verify all existing conditions necessary to be addressed for the pricing of this subject project. All disposal costs and fees for debris removal will be the contractor’s responsibility. The contractor will be responsible for cleanliness of the building area exterior and providing their own dumpster on site.
11. Safety Considerations Contractors shall provide and utilize all safety requirements in accordance with OSHA regulations in the performance of the work.
12. Notes
a. The Contractor shall submit ALL samples, including manufacture’s literature, of newly proposed materials for approval. No materials shall be procured or installed prior to the approval of the samples.
b. Site shall always be kept clean and free from debris, and the contractor shall remove debris daily from the health care system property. Contractor will not be allowed to use Government tools, materials, and/or labor for this project.
