NEED A DALLAS GREEN BUILDING CLEARANCE INDOOR AIR QUALITY (IAQ 804.2) QUOTE ?

Please provide the following information:

  • 1) Physical address of the site including Suite # if applicable and nearest major intersection as often these are new builds that are not on Google Maps
  • 2) Square footage and number of floors and AHU (Air Handler Units)
  • 2) Nature of the facility (office building, restaurant, etc.) and the NAME (such as First Citizen’s Bank, Valero gas station, etc.) so it can be more easily located upon arrival
  • 3) How soon you need the survey and how soon your site will be ready for a Green Building IAQ Survey (see next # 4)*
  • 4) How far along the construction is as far as the punch list is concerned. This is IMPORTANT because if you only have half the electrical working, no HVAC, the place is swarming with subcontractors then performing the test correctly may be impossible
  • 5) Who will be onsite as certain kinds of work (sanding, drilling, etc. ) can either interfere with the results or impede the ability to assess the indoor air quality. It would be unfortunate to have to be charged twice because some of the above was overlooked
  • 6) Access logistics such as key combos, meeting with the onsite superintendent, where to park, enter the building etc.
  • 7) Who your 3rd Party Green Provider is as the report needs to be emailed to them and you will be cc’d / copied on the results
  • 8) Path to payment (check, credit card, etc.) and for TCO / CO jobs ScanTech typically gets paid at the time of service because a later date could be difficult because of travel, etc.

* Rush fees may apply depending on amount of notice and project load.

Please indicate what kinds of finishes have been applied such as oil stain, epoxy, low VOC latex, etc. and WHEN they were applied because that could push the VOC levels too high to pass.

Dallas Green Building Post-Construction IAQ Clearance Testing for 804.2 Certificate of Occupancy

* TIPS TO PASSING THE DALLAS GREEN BUILDING CLEARANCE POST CONSTRUCTION INDOOR AIR QUALITY TEST:

  • Use low-VOC paints and in cases where you have to use oil based paints and stains, try to do those earlier in the construction phase so that they have more time to outgas.
  • When it is warmer outside, run the HVAC system to help flush the air (particularly if you are able to dilute it with makeup air)  and / or keep at least two doors that are diagonal from each other in the facility to create a cross draft through the building. Depending on what phase of construction you are in, how easy it is to access the building, the local neighborhood, etc. it is good to balance this with necessary physical security measures to protect your workers and the property.
  • When it is cooler outside, running the HVAC on heat can help as well. In general, outgassing happens faster the WARMER and DRIER the air.
  • In rooms that have heavier use of epoxy paints, stains on wood, oil base on trim or other strong odorous solvents, keep the doors open when possible to assist in flushing out the room.
  • Time the survey so that you have the best chance of passing. If it has been a few weeks or more since the finish out, the chances are very good.
  • Try to schedule the survey when no subcontractors are on site as they may be performing activities (touch up paint, mixing solvents) that can artificially raise your TVOC (Total Volatile Organic Compound Levels)

Back in September of 2011, Dallas established a Green Post Construction Indoor Air Quality test for new and renovated buildings which pertain to the VOC levels and general indoor air quality in accordance with Ordinance 804.2 for Post Construction & Pre-Occupancy Baseline IAQ Testing.

Originally it was much more complicated to perform as shown in the above chart, but later the ordinance was amended to having TVOC (Total Volatile Organic Compound) levels at less than 500 micrograms per cubic meter. ( < 500 ug / m^3)
