All construction and renovation projects are expected to meet or exceed the recommendations contained in the most recent edition of the SMACNA document “IAQ Guidelines for Occupied Buildings under Construction.”
Construction and renovation projects adjacent to occupied spaces present additional IEQ concerns. It is not uncommon for odors, noise and dust from projects to create problems for the adjacent occupants.
Exposures to even low levels dust or chemical contaminants can cause or aggravate asthma, allergies, headaches and mucous membrane irritation in building occupants. The following specific recommendations are intended to prevent these problems.
Areas under renovation shall be separated from adjacent occupied areas by full height hard wall barriers. The barriers are intended to block the transmission of dust, odors and other contaminants from the work area to the occupied spaces.
The work area shall be maintained at a slight negative pressure relative to the adjacent occupied space. Negative pressure can be achieved through adjustment of the HVAC system or by the addition of additional exhaust ventilation in the work areas.
A test and balance of the HVAC system will be required following project completion when pressure adjustment is made through manipulation of the HVAC system.
Regular (daily) housekeeping shall be performed to prevent the tracking of dust and debris from the work area into occupied spaces.
Odor or contaminant producing equipment set-up outside of the interior work area must be located away from outside air intakes or building entrances. Examples of such equipment include roofing tar pots, portable gas or diesel powered engines and portable lavatories.
Workers involved with the project must follow the requirements of the University’s smoking policy.
Material Safety Data Sheets (MSDS) shall be maintained on site for all chemical products used during the renovation or construction process.
