Having handled 20 years of municipal solid waste and construction debris, the concrete floor slab at the base of the Pickens County Class III Transfer Station was deteriorating. Pickens County asked Davis & Floyd to plan the slab’s demolition and reconstruction on a fast-paced schedule as construction required closing the transfer station to the public.

We evaluated the existing slab, planned demolition, and designed a new structure that would better support the transfer station’s workload. Our team crafted two design options, outlining costs and time frames.

Due to deterioration to the slab’s subgrade, the county ultimately chose to demolish and replace the slab, the most durable solution to extend the service life of the transfer station.

Because structural drawings of the 4,200 SF existing station were unavailable, we developed an innovative procedure to determine its supportive structure. Our team installed temporary bracing, removed a section of deteriorated slab, and inspected the reinforcing and subgrade underneath. By revealing the slab did not provide lateral support, we saved time and cost on this project.

Our plan to address this solution included specifications for the extent of demolition, temporary support requirements, and modifications to the slab’s existing structure. Our recommended design elements would preserve the new slab, preventing similar and future deterioration. These included slope dimensions and floor drains to accommodate rainfall, slab protection and durability measures against the heat of sunlight, and steel rebar and concrete for long-term preservation of the station’s viability.
