Construction IAQ Management Plan - EQc3

Implementation During Construction
  • Identified an on-site Indoor Air Quality Management Coordinator (IAQMC) for the project
  • Appointed an on-site indoor air quality management individual for each subtrade
  • Followed a Volatile Organic Compound (VOC) Plan that regulated the procurement, use and documentation of VOC materials on the job site
  • Followed a Source Control Plan that prohibited equipment re-fueling or fuel storage inside; prohibited lubricant spillage (pipe threading oil) within the building; employed shields and curtains to contain metal cuttings and dust; collected and disposed of sawdust; covered or sealed all indoor sources of dust; protected all equipment and furnishings from dust, and; protected porous materials from moisture
  • Followed a Pathway Interruption Plan that erected dust curtains to minimize dust and odour migration; used portable fans to exhaust pollutants; closed windows and doors exposed to exterior pollutants or weathering threats; conduct pollutant-causing work in low IAQ impact areas (low draft, small, contained areas)
  • Followed a Housekeeping Plan that frequently cleaned dust; used HEPA filtration with vacuum equipment; used sweeping compounds or wetted agents; cleaned spills promptly; removed accumulated water; covered, sealed and protected on-site materials from moisture, dust and dirt; prohibited materials from being placed directly on the ground
  • Followed an IAQ Scheduling Plan that minimized cross contamination and re-contamination by completing paint and sealant coatings before installing ceiling tiles and carpets; completing all work and final cleaning prior to permitting building occupancy
  • Followed an HVAC Protection Plan that covered equipment and stockpiled components with plastic during construction; closed hatches and doors when equipment was not be worked upon; sealing supply and return duct openings during all phases of installation; prohibiting the mechanical rooms from being used to store construction waste materials
  • Conducted and passed a baseline IAQ test for indoor air pollutants such as VOCs and formaldehyde

Contaminant Maximum Concentration Allowed Actual Concentration **
Particulates (PM10) 50 micrograms per cubic meter (μg/m3) 25 μg/m3 to 34 μg/m3
Formaldehyde 50 parts per billion (ppb) 7 ppb to 11 ppb
Total volatile organic compounds (TVOCs) 500 micrograms per cubic meter (μg/m3) < 140 μg/m3 in all locations (below low limit of detection)
Carbon monoxide (CO) 9 part per million (ppm) and no greater than 2 parts per million above outdoor levels 0.6 ppm to 1.1 ppm
4-Phenylcyclohexene (4-PCH)* 6.5 micrograms per cubic meter (μg/m3) N/A
* This test is only required if carpets and fabrics with styrene butadiene rubeer (SBR) latex backing are installed as part of the base building systems. Since the carpets and fabrics used in the building did not contain SBR the 4-PCH testing was not required.
** Measurements were taken from 5 different interior locations within the building on October 9, 2012.
