SCOPE OF WORK: The Project is for the South Dade Landfill, for Roof and Structural Repairs for 40-Year Recertification of Buildings 3 & 4, located at 23707 SW 97th Ave, Homestead, Florida 33032. Please note that the new roofing system, metal deck, metal roofing panels, skylights, roof hatches, and any other building components must be approved by Miami-Dade County Product Control and have a valid Notice of Acceptance (NOA). All work under this Contract consists of furnishing the labor, materials, tools and equipment necessary to perform the work including the partial demolition of Building 3, as outlined in the construction drawings, the replacement of the remaining membrane roofing system and insulation at both buildings; the construction of a new metal fascia at the remaining façade (South) of Building 3; the repairs to the enclosure of the existing stairs to the offices at Building 3; the repair/replacement of metal roofing panels at Building 4; the repair of concrete cracks, spalling and rebar corrosion at both buildings (in response to deficiencies cited in the 40-Year Recertification Reports prepared by Cueto Engineering).

Remove loose paint from the structure to remain and prepare to receive new paint. Please note that the existing paint is considered lead-based paint under the Occupational Safety and Health Administration (OSHA) regulations but not under the United States Environmental Protection Agency (EPA) regulations (work must be done using personal protection but debris will be disposed of as construction debris). 4.
