Containment structure. Polyethylene sheeting to enclose the contaminated area. For a large job,
containment should extend from the affected area to the building exterior. Includes fabrication, cleaning,
removal and typical loss due to waste. Cost of the support frame assumes five uses of materials.

Antimicrobial cleaning. Using a sprayer, sponge and sponge mop on non-porous or semi-porous
surfaces. Cost per 100 square feet (CSF) of surface sprayed or cleaned. An open wall or ceiling cavity
has about 1.5 SF of surface area for each square foot of wall or ceiling. Spraying assumes the surface
is kept moist for 10 minutes. Add the cost of an EPA-registered disinfectant-sanitizer-cleaner
(bactericidal, virucidal, tuberculocidal, fungicidal). Work done in containment and personal protective
equipment (PPE) will take about 50 percent longer.
