Specifications include, but are not limited to: Degreasing, Power-Washing, and Sweeping of Parking Garage The parking garage is open for use by employees and members of the public. To prevent premature deterioration of the concrete structure, RIDOT is implementing practices and procedures for housekeeping and preventative and general maintenance of the structure. Grease and Oil Cleaning Grease and oil from cars build up in parking spaces as well as in entrance and exit lanes. These grease and oil buildups must be removed with an appropriate EPA recommended degreaser such as an industrial detergent. The Contractor will be responsible for removing all debris off site. These de-greasing services shall be performed twice per year. Power-Wash of Parking Garage A wash down of the parking garage floors and stairwells, with high-pressure high-volume water hose (i.e., power wash) and use of a surface clean designed for concrete cleaning is required. Prior to any power-wash services being performed, the Contractor must (1) remove all sand, (2) sweep the garage and stairwells free of debris to minimize the amount of debris that will collect in the drains, and (3) install temporary filters such as burlap or straw in all drains to prevent sand and debris from clogging the drains. The filters must be removed immediately after washing and after all debris has been removed.
