Thinking

Find that late, missing and poorly coordinated deliveries of concrete threaten the quality of concrete finishing jobs. They find extra labourers to help pour, rake and level the concrete and encourage their co-workers to work quickly to finish the over-mixed concrete, which sets more rapidly. (2)
Find that preparatory work on job sites is inadequate. They ask labourers to carry out preparatory work according to specifications, to ensure that forms are level and that gravel is deep enough. They notify site supervisors of delays. (2)
Discover that work sites are inaccessible and concrete deliveries cannot be made as planned. They inform their supervisors and call for pump trucks. They contact suppliers to send retardants to slow down the setting process. (2)
Experience equipment breakdowns during finishing jobs. They try to repair equipment before the concrete becomes unworkable. If repair efforts fail, they work with available hand tools and call supervisors to request additional workers. They may also attempt to delay the setting and curing processes by using retardants. (2)
Choose tools, methods and products for concrete finishing and repair, e.g. consider the consistency of the concrete, weather conditions and the availability of time and labour when selecting concrete finishing techniques. (2)
Decide on the order of tasks and their priorities, e.g. decide the order in which to pour concrete footings. (2)
Decide to report unsafe work conditions, e.g. act on requirements to report unsafe work conditions by discussing their concerns and decisions with co-workers and supervisors. (2)
Evaluate the safety of work sites. They observe elements, such as available space to manoeuvre around large vehicles and the presence of proper ventilation units, guard rails and safety cones. They consider the stability of access ramps for trucks. They take note of potential hazards, such as improperly stored tools and broken equipment. (2)
Evaluate the preparedness of job sites for pouring and finishing concrete. They consider adequate access for deliveries of concrete and aspects, such as sufficient lighting and protection from air currents for finishing. They also assess elements, such as the accuracy and solidity of formwork, the proper placement of rebar and depth and evenness of gravel beds. (2)
May plan finishing tasks on several work sites, taking into account the time for concrete to set and cure. Their job task plans may be disrupted by weather conditions, rush jobs and unexpected repairs. They provide supervisors with time estimates for job rescheduling when necessary. (2)
Find information about concrete finishing jobs. They speak with supervisors, site managers, other tradespeople and clients to learn about project specifications and work sites. They review work orders and technical drawings to locate information, such as dimensions and the locations of drains and underground cables. They may read tenders and worker orders to learn about upcoming projects. (2)
Find information on the operation and maintenance of new equipment by reading instruction manuals, viewing videos and by talking to co-workers and equipment suppliers. (2)
Learn about job hazards by inspecting job sites, reading Material Safety Data Sheets, participating in safety briefings and speaking with co-workers. (2)
May select equipment and suppliers, e.g. decide which brand and type of equipment to use on projects by considering specifications, costs, ease of use and personal preferences. (3)
Assess the quality of concrete finishing jobs. They take measurements, observe the appearance and consistency of concrete, check for hairline cracks and evaluate the aesthetic appearance of decorative concrete work. (3)

Digital Technology

Use calculators and personal digital assistant (PDA) devices to complete numeracy-related tasks, such as calculating material requirements. (1)
May use word processing software to prepare job estimates and invoices. (2)
May use spreadsheets to tally costs for job estimates and invoices. (2)
May use databases to retrieve forms, such as change orders. (2)

Additional Information

Other Essential Skills:

Working with Others

Concrete finishers coordinate and integrate job tasks teams with other finishers and labourers to complete jobs rapidly. They also coordinate job tasks with drivers, surveyors and other tradespeople on work sites.

Continuous Learning

Concrete finishers typically learn on the job. They watch members of their work units demonstrate new finishing techniques and they discuss concrete finishing and workplace safety with them. They may read product labels and forms to learn the handling and use of new products to treat and cure concrete. They may occasionally take health and safety workshops and trade skills training provided by their employers.

Impact of Digital Technology

All essential skills are affected by the introduction of technology in the workplace. Concrete finishers’ ability to adapt to new technologies is strongly related to their skill levels across the essential skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. For concrete finishers in particular, the use of technology, such as billing software, is becoming more prevalent, especially for those who are self‑employed. For example, they may use bookkeeping, billing and accounting software to input and track sales, produce invoices and estimates and print reports, such as income and expenses statements; or they may use communication software to exchange emails with clients, suppliers and co‑workers. Digital technologies also provide these workers with tools, such as cellular telephones, that increase opportunities for verbal interaction and improve workplace safety. For example, workers working independently in remote locations can access clients, supervisors and medical assistance using their cellular telephones.

Technology in the workplace further affects the complexity of tasks related to the essential skills required for this occupation. Workers need the skills to use increasingly complex and specialized software applications. At the same time, software and hardware developers are improving ease of use for workers through touch‑screen technology, built‑in self‑help tutorials and more user‑friendly software applications. Workers can complete documents, such as work orders, with speed and accuracy using software applications that input data automatically. Hand‑held devices and Web‑based applications can also be used to calculate costs, material requirements, conversions, volumes and rates. For instance, they may use computer‑controlled layout equipment, such as total stations and smart levels, to determine the location, slope and angles of foundations and precast concrete panels.
