3.2 UTILITIES

All utilities required to complete the work specified shall be provided by the government, provided that such utilities are currently in place and are usually and reasonably available at the work site.

3.3 SURFACE PREPARATION:

a. Contractor shall verify all necessary field measurements and dimensions. Commencement of work by the Contractor implies acceptance of all known site conditions.

c. Prior to concrete surface preparation and Floor Surfacing System applications, remove, mask, or otherwise protect, hardware, hardware accessories, machined surfaces, radiator covers, plates, lighting fixtures, public and private property, and other such items not to be coated that are in contact with surfaces to be coated. It is the Contractor's responsibility to restore any and all surfaces and property contaminated by contact with or exposure to preparation and Floor Surfacing System materials, to original condition and repair or replace damaged items.

d. The Contractor shall thoroughly clean all surfaces to be coated, before application of the coating system. If the removal of the floor coating is required then the following method shall be used. Clean the entire substrate area of all existing coat system materials by one of the following: shot blast system, scarification, sand blast, sanding, or dry-prep (mechanized sanding in combination with abrasive media). The chosen method of coating removal will provide a floor surface that is sound, dry, free of dust, dirt, grease, paint, oil, other foreign substances, and that is smooth without evidence of coating removal equipment ridges or overlap lines. The floor shall be cleaned down to the existing bare concrete surface.

e. The equipment used shall be dry, closed-cycle with residue and abrasive vacuumed up or otherwise recycled. During blasting, airborne dust, debris, or other particulate matter shall be fully contained. Any compressed air used for shot blasting must be clean and free of oil. Equipment shall be suitable for use in sensitive areas where airborne contaminants are not acceptable. When shot blasting equipment is utilized in removal of an existing coating and/or for preparation of concrete floor, a resurfacer/floor leveler shall be applied such that the resulting surface profile is smooth as like new concrete. The required mil thickness of the resurfacer/floor leveler will be determined based on the profile of the surface after the coating is removed.

f. The floor leveler shall be an 100% solids epoxy coating suitable for use on concrete floors. The coating shall achieve a chemical and mechanical bond to the concrete and provide a level bonding surface to accept primer and topcoat such that the results will provide the required smooth surface that will provide the highly reflective surface.

g. The Contractor shall be responsible for correcting any damage to the concrete floor during the surface preparation. The surface preparation instructions of the manufacturer of the reflective coating system shall be followed. The steps listed below are given as a guide only, and more preparation work may be needed. It is the contractor’s responsibility to complete the work as required to insure the proper bond.

h. Contractor shall remove all existing paint, paint overspray, or markings that may prevent proper adhesion of the Floor Surfacing System.

i. Contractor shall remove all concrete surface contaminants such as dirt, grease, oil, fungus, mold, etc. using a cleaning and degreasing solution.

b. In areas where the use of Manufacturer's generally recommended application rollers, pads, sprayers, or other methods may not be feasible, Contractor shall cut in the Floor Surfacing System using paint brushes or other suitable application methods as approved by the Manufacturer.

c. All finished surfaces will be free from runs, drops, ridges, waves, laps, brush marks, or variations in color or texture.

d. An itemized list of all materials and specific quantities used to prepare and surface the floor shall be provided by the Contractor for verification by the Government that adequate and appropriate amounts of all materials have been used. Any and all empty or partially used containers shall be retained on the job site in an area designated by the Contracting Officer for inventory and comparison to the Contractor's provided itemization. The Contractor shall not remove from the job site or otherwise dispose of any such containers until and unless specifically directed by the Contracting Officer.
