IAQ and IEQ during construction & renovation or building cleaning operations:
This article describes the common indoor environmental issues for occupied buildings during construction, renovation, or remodeling and for occupied buildings adjacent to and impacted by such construction projects. We provide references to authoritative information sources giving advice on management of indoor air quality and the indoor environment for construction environments.
Our page top photograph illustrates a large construction project underway on the Vassar College campus in Poughkeepsie, New York in 2013. A new sciences building is under construction on a job site placing major building activity adjacent to an occupied academic building.

Writing in a recent issue of The Synergist, a publication of the American Industrial Hygiene Association, Weekes, Baker and Springston (2004) describe the range of indoor environmental contaminants that may affect the quality of the indoor environment during construction, including airborne particles, VOCs, and in some cases biological contaminants such as mold spores.

Any of these can result in IAQ complaints by building occupants ranging from skin irritation to respiratory or other health complaints and potentially respiratory distress, particularly for people at extra risk such as asthmatics.
What are the Common Indoor Environment or IAQ Hazards Arising During Construction?
That list expands upon the particulate irritants described above to include potentially troublesome contaminants such as carbon monoxide (CO), Formaldehyde, VOCs, Ozone, as well.
The USGBC document describes both recommended maximum concentrations of these contaminants and the test methods used to evaluate their levels in a building.
Illustration at left: NIOSH illustration of sealing penetrations to improve building IAQ. Note that this is one example of multiple coordinated steps that should be taken in concert.
NIOSH in the IEQ article cited below, simplifies the indoor environment concerns arising during construction to three categories:
What are the Common Indoor Hazard Control Measures Used During Construction?
To address these potential hazards during a construction project the job managers are invited to prepare and follow an Indoor Air Quality (IAQ) management plan that specifies various control measures such as
As steel construction continues atop the concrete foundation and walls of this new building underway adjacent to an occupied building (background in my photo), processes include grinding, cutting, and welding operations that may add to airborne particulates.
Where do the SNAFUs Occur during Indoor Environmental Quality Management During Construction or Remediation?
I suspect that whether we are monitoring indoor building conditions during construction or before, during and after an asbestos or mold remediation project, among these measures, failures in IEQ management and monitoring usually occur in these areas:
Useful References for Building Indoor Air Quality and Indoor Environmental Quality During Construction
Weekes et als, (2014) suggested some of these construction IAQ IEQ resources while others are cited from the U.S. EPA IAQ Design Tools for Schools web page.
