Automation of Concrete Slab‐on‐Grade Construction

Automation and Robotics in Construction Xi

“…A comprehensive productivity analysis of the concrete slab-on-grade construction has been described in an earlier study (Moselhi et al 1992) and will be briefly summarized here for continuity. The data collected from the 15 sites was used to model concrete placing productivity, defined as the number of man-hours required to place one cubic meter of concrete, for a 150mm (6 in.)…”

“…machine. Comparatively, the reported productivity of floor finishing robots (Moselhi et al 1992) varies from 300 to 800 m2/hr (3,228 to 8,608 ft2/hr).…”

“…Work task breakdowns and crew sizes for each level of automation are given in Table 1, and are based on the construction practices in the Montreal area described in an earlier study (Moselhi et al 1992). It must be noted in Table 1 that robotic finishing, in accordance with the contractors' comments, is assumed to be performed only for troweling: floating operations are performed with the mechanical power trowel.…”
