INTRODUCTION

The mission of the Indoor Air Quality Task Force is to create a more productive learning
environment for school children through indoor air quality. Improved indoor air quality
should decrease absenteeism and respiratory illness in schools. Studies have shown
that:

1. Indoor air quality and relative humidity in buildings is directly linked to the
health of its occupants.

2. In schools, absenteeism and the transmission of colds have been found to
correlate to the relative humidity and the indoor air quality.

3. Children do not have fully developed immune systems, and are more
susceptible to disease transmission, respiratory illnesses, and allergic
reactions.

4. Low humidity causes dryness of the throat and mucus membrane, making
one more susceptible to disease transmission.

5. Respiratory illnesses are at their peak in winter, when humidity is the lowest.

6. Molds and fungus grow when humidity is too high, which can cause allergic
reactions.

7. At higher humidities, flu viruses do not spread as fast.

The following is an outline of Architectural specification recommendations developed by
the task force to improve indoor air quality in school buildings, both new construction
and remodeling.

SPECIFICATION RECOMMENDATIONS



DIVISION 1 - GENERAL REQUIREMENTS


A.
Section 01010 - Summary of Work:

Recommendations:


1.
Sequence of Work: Establish a timeline of activities: include the time


periods in the construction schedule for the following issues:



a)
Off-gasing of materials: Provide schedule that includes time for



material off-gasing prior to occupancy. Refer to off-gasing
timeline
in
individual
sections.



b)
On the project schedule, provide for sequencing of work to ensure



appropriate environmental conditions for products to be installed
under
manufacturers
recommendation.



c)
Provide adequate time for concealed work to be reviewed by



Architect prior to being covered (example: vapor barriers, etc.).



d)
Include time allowance for environmental testing after Off-gasing



periods, etc., prior to occupancy.



e)
Do not allow work which generates particulate which could be



concealed by previously installed systems (example: drilling
above
ducts,
etc.).


2.
Contractors Use of Premises



a)
Prohibit on-site smoking or use of tobacco.



b)
Isolate from construction areas locations of lunches/breaks where



food cannot be left in walls, etc. Prohibit food/beverages in work



areas. A designated area for consumption of food and beverages
must
be
provided.



c)
Contractor to immediately notify Architect or Owner of wet



condition and provide follow-up correction.



d)
Contractor is responsible for security of building to prevent water
damage.



e)
Prohibit tools that create pollutants when site is enclosed, such as
generators,
etc.



f)
Provide appropriate storage of hazardous materials (fuel, paints,



etc.). This should be in a designated storage area, isolated in a

trailer, separate from the building. Storage of fuel oils-to be in a



heated trailer outside of the building.


B.
Section 01040 - Coordination:

Recommendations:

1.
Project
Coordination



a)
Specify coordination of trades when concealing work or providing
proper

environmental
project
requirements.



b)
Specify coordination of concealed work to be reviewed by



Architect: A/E team tags areas that have been reviewed.


2.
Job Site Administration



a)
Contractors supervisory staff to be made aware of indoor air



quality concerns and project requirements.



b)
Attend IAQ training, 4 hours for job superintendent - could be a
video
of
procedures.



c)
Require all trades attend IAQ training, 1 hour.



d)
Review IAQ issues at weekly OSHA meetings.



e)
Get rid of not my job philosophy at jobsite regarding IAQ



f)
Promote timely decisions from Owner and Architect regarding IAQ



issues, otherwise penalties will be imposed.



g)
Post special instructions and procedures related to IAQ for


products at the construction site. These posted instruction sheets


would be included in the specifications appendix, and would list


instructions for specific procedures for indoor air quality for a

particular
product.



C.
Section 01045 - Cutting and Patching:

Recommendations:


1.
Ensure temporary barriers are dust-free, contain the debris; provide


dust-free openings. Provide complete enclosure of openings.
