I am preparing specs for a large expansion to a resort in Barbados, the Resort owner wants extraordinary means specified to control dust traveling from the expansion site to the existing resort next door. Other than enclosing the expansion site in a dust cover, anyone have any suggestions on wording to add to the standard Execution Requirements of Division 1.
Either build upwind or install some Big Ass Fans .
Construction dust would be generated by demolition and earthwork. For earthwork, it should be possible to require the contractor to cover loose soil that has been stockpiled, and “wet down” loose soil and construction-generated dust. The civil engineer should have language about this in their Division 31 specifications. For demolition, include language in the Division 02 demolition specifications requiring that the contractor use wet sawing where concrete and masonry needs to be cut and keep the construction site clean. In both Division 02 and 31 the specifications can require that the contractor submit their proposed methods for controlling dust - they may have other methods at their disposal.
You can also require truck wash stations that clean dirt off wheels and undercarriages to limit dust on local access roads, along with regular road-sweeping.
Here is a product I have used for dust control:
U. Synthetic Soil Binder: Durasoil synthetic organic dust control agent, as manufactured by Soilworks, LLC, or other standard manufacturer’s spray on adhesives designed for dust suppression.
- Product shall be non-toxic, non-disapating, non-curing, colorless, and odorless.
- Product shall be capable of being applied in any weather conditions.
Thanks Greta, John, & David much appreciated feedback.
Ron, there are no words for my gratitude for your recommendation, I think I will pass though, I want to keep this client.
Dust control is not impossible, but it does slow construction progress and add cost. Here in Maricopa County, Arizona the dust control requirements are very strict. Just driving a vehicle down a dirt road can get you a citation if you create dust.
Isn’t this why water was invented?
Seriously, I had never heard of the product David has used. Aside from specifying dust control products, isn’t dust control a means, methods, and sequencing responsibility issue for the contractor. Perhaps there is local AHJ or EPA requirements for dust control.
Wayne, Ron, this is Barbados, EPA does not scare these guys like it does us in the States. The Resort wants extraordinary methods used to insure their guests don’t get dust in their Mai-Tais.
Jerome,
I suggest you look to existing requirements for dust control found in the US. EPA and jurisdictions like Maricopa County may be a good starting point.
Jerome,
Here is one source of information
http://water.epa.gov/polwaste/npdes/swbmp/Dust-Control.cfm
You may find something in this website to aid your dust control requirement specification.
Jerome:
Yes, Barbados may not have the EPA or Maricopa County regulations, but you have an owner requirement, which is just as binding on you as a governmental requirement (albeit without the mandated heavy fines).
Here’s Rule 310 from Maricopa County: https://maricopa.gov/aq/divisions/planning_analysis/rules/docs/310-1001.pdf
David, the Resort client nixed your idea, apparently there are too many chemicals being used there as is, they want to keep it simple.
