Major Work Activity B - Performs site preparation

Table of Contents

Task B-5 Prepares site

Task Descriptor

Site conditions are extremely important to concrete finishers. They impact the timing and sequencing of many of the procedures involved in the concrete finishers’ work. Concrete finishers may perform site inspections before the preparation of the site can begin. Site preparation could include determining elevations and preparing the sub-grade prior to placing concrete.

Task B-6 Uses formwork

Task Descriptor

Concrete finishers use formwork to hold and mould concrete or grout in place while the surface is being worked. They may be responsible for the construction of concrete formwork and the removal of formwork once the concrete or grout is set. They will install construction, expansion and isolation joints with formwork as a permanent fixture of the concrete. These joints are often filled with self-levelling caulking or other compounds.
