It is stated that, "Polishing shall be a dry diamond method with a machine capable of a grinding pressure of 675 or more. The grinder shall be connected to a vacuum system with HEPA filtration." A vacuum that has HEPA filtration only means that it will filter particulate debris that it "actually collects" to the HEPA specification. There are no vacuums currently on the market for grinding concrete that has the ability to "lift and contain" the heavy particulate generated during the initial grinding stages of the polishing process. To help reduce possible silica exposure to workers and other trades from the initial grinding stages can a contractor use a wet method for the initial grinding, then switch to a dry method at which point the available vacuum systems on the market are able to lift and contain the particulate debris? See Amendment No. 0004

It is stated, "The system shall be capable of meeting the following performance requirements: Floor Flatness: 45 Minimum." Floor Flatness is dictated by the contractor placing and finishing the concrete. Small aggregate exposure has been specified as the desired cut. Aggregate placement will vary in depth from one place to the next throughout the slab. These two variables are going to affect the finished floor flatness of the polished surface. To what extent is the polishing contractor going to be held to a 45 minimum floor flatness and a uniform exposure of small aggregate? See Amendment No. 0004
