11,111ro J e .� � � �:� �ruir�i �m�i ��c uir" �t uia�.� )� iur uu �, � tau Polar Clean will provide wet abrasive media blast cleaning of the parking garage's ceiling peeling paint surfaces. The purpose of this cleaning is to remove white, peeling paint from the concrete surfaces of the ceiling. Based on the information received to date, it is our understanding that the following information is descriptive of this project: • Client has stated that there is no lead paint present on the ceiling in the garage. • The total surface area requiring blasting is approximately 131,000 square feet. Including: o The ceiling on levels 0,1,2,3, and 4, including the main entrance/exit. • Polar Clean to work closely with the City of South Bend to ensure there is environmentally responsible disposal and containment throughout the process. • All storm drains that can be affected by the paint removal blasting process will need to be sealed off. • Client to supply Polar Clean with a staging area along the Woodward Ct. on the East side of the garage for equipment staging as needed (dumpster, vehicles, etc.). • Detailed project logistics and garage operations are to be determined once both parties align on schedule and develop a clear project plan. o The garage must remain operational during the day from 6:30 a.m. —10:00 p.m. o The garage can be shutdown completely during the night hours of 10:00 p.m. — 6:30 a.m. Job Site: Main & Colfax Garage, South Bend Job Date: To be determined as mutually discussed and agreed upon by both parties but to be completed by April 30ll', 2020. Shift Start and End Times: To be determined as mutually discussed and agreed upon by both parties. Industrial Cleaning Method: µ Wet Abrasive Blast Cleaning — This system propels various abrasive media with high pressure compressed air and water to clean the surface. Apy icatiou Surface: Please note the following: • Concrete: Due to the many uncontrollable variables contributing to the quality of the concrete, including the age, type, general maintenance, and environmental conditions, the restoration process can be more complicated. There are risks associated with cleaning porous concrete, including pitting and discoloring, and etching. It is strongly recommended that an Application Validation cleaning is conducted on a less - consequential area to establish the protocol for the cleaning project. Any surface repair work is an additional cost to the Client and is not the responsibility of Polar Clean. • Porous Surfaces - Staining, shadowing: Any surface that is porous may retain a staining even after the surface is cleaned thoroughly. This staining or shadowing should be taken into account by the Client prior to the project onset to determine if the level of clean is satisfactory. Adherents To Be Removed: Polar Clean cannot attest to the chemical nature of the adherents. Because there are an infinite number of chemical products and environmental conditions that change the nature of the adherent to be removed, Polar Clean cannot guarantee the results of the blast cleaning unless an Application Validation is performed and explicit expectations are established. Client is required to provide relevant SDS sheets to Polar Clean prior to the onset of the project.
