Construction IAQ management plan - during construction

EQc3.1 | Possible 1 point

Intent

To reduce indoor air quality (IAQ) problems and noise and vibration resulting from construction and/or renovation process in order to help sustain the comfort and well-being of construction workers and building occupants.

Requirements

Develop and implement an Environmental Quality Management Plan (EQMP) for the construction and preoccupancy phases of the building. Minimize air and noise pollution during the construction process as prescribed below. For renovations, additions adjacent to occupied facilities or phased occupancy in new construction:

  • Follow the 2010 FGI Guidelines for Design and Construction of Health Care Facilities and the Joint Commission on standards to establish an integrated infection control team comprised of the owner, designer and contractor to evaluate infection control risk and document the required precautions in a project-specific plan.
  • Use the Infection Control Risk Assessment (ICRA) standard published by the American Society of Healthcare Engineering (ASHE) and the U.S. Centers for Disease Control and Prevention (CDC), as a guideline for construction activities to assess risk and to select mitigation procedures.
For all projects:
  • Develop and implement a moisture control plan to address measures that will maintain dry conditions to protect stored on-site and installed absorptive materials from moisture damage. Immediately remove from site and properly dispose of any materials susceptible to microbial growth and replace with new, undamaged materials. Also include strategies for protecting the building from moisture intrusion and occupant exposures to dangerous mold spores.
  • If permanently installed air handlers are used during construction:
    • Filtration media must be used at each return air grille that meets one of the following criteria below.
      • Filtration media with a minimum efficiency reporting value (MERV) of 8 as determined by ASHRAE Standard 52.2-1999 (with errata but without addenda1)
      • Filtration media is Class F5 or higher, as defined by CEN Standard EN 779-2002, Particulate air filters for general ventilation, Determination of the filtration performance
      • [East Asia ACP: Construction IAQ Equivalent]
      • Filtration media with a minimum dust spot efficiency of 30% or higher and greater than 90% arrestance on a particle size of 3–10 µg.
    • Protect active outdoor air intakes and return air grilles with filtration media.
    • Temporary filter media must be evaluated and replaced as necessary.
    • Replace all filtration media immediately prior to occupancy.
  • Volatile Organic Compound (VOC) Absorption – Schedule construction procedures to minimize exposure of absorbent materials to VOC emissions. Complete “wet” construction procedures such as painting and sealing before storing or installing “dry” absorbent materials such as carpet or ceiling tiles. These materials accumulate pollutants and release them over time. Store fuels, solvents and other sources of VOCs separately from absorbent materials.
  • Tobacco Products – Prohibit the use of tobacco products inside the building and within 50 feet (16 meters) (or greater, if local jurisdiction requires) of the building entrance during construction.
  • Noise and Vibration Exposure to Occupants and Construction Crews – Develop a plan based upon the British Standard (BS 5228) to reduce noise emissions and vibrations from construction equipment and other non-road engines by specifying low-noise emission design or the lowest decibel level available that meets performance requirements in the British Standard to insure it is within acceptable limits to the occupants. Construction crews must wear ear protection in areas where sounds levels exceed 85 dB for extended period of times.

Alternative Compliance Paths (ACPs)

East Asia ACP: Construction IAQ Equivalent

Projects in East Asia may use filtration media classified as medium efficiency (中效过滤器) or higher as defined by Chinese standard GB/T 14295-2008(空气过滤器).
