Measurement and Calculation
  • Measure lengths or thicknesses using a tape measure. (1)

Job Task Planning and Organizing
  • Plasterers, drywall installers and finishers and lathers are typically assigned work tasks in a prioritized order. Within that framework, however, they have latitude in choosing how they will approach each job and what tools they will use in the process. They must be able to visualize and "scope out" a job, considering factors such as placement of walls, thickness of multiple elements that make up the wall and finish elements, openings and applications. Materials once calculated must be stored in reverse order, making the first used, most accessible. While much of the work is routine, each work site varies somewhat and it is not uncommon to face new and unfamiliar design challenges in construction and renovation. Organizational skills are key. Coordinating work with co-workers, apprentices and other trades is critical, often under tight time constraints. Disruptions, such as electrical failure, are not uncommon and may require re-sequencing of assigned work tasks. (3)

Decision Making
  • Decide what tools to use, weighing factors such as speed, accuracy and noise. A chop saw, for example, while efficient, may generate too much noise in some settings. (1)
  • Decide how to approach a job assignment, including the best way to complete the job efficiently and cost-effectively. (2)
  • Decide what size to make an opening, allowing for the thickness of materials. (2)
  • Decide upon materials or methods of construction, depending on the context, cost implications and design specifications, while still complying with industry standards. You may, for example, choose to use 2 and 1/2 studs instead of 3 and 5/8 studs as a cost savings measure for a furring wall, but could not exercise the same discretion on a load-bearing wall. (2)
  • Make decisions about placement of materials or equipment. For example, where to place a dumpster, considering factors such as traffic flow, security, damage to the landscape or accessibility to the construction site. (2)
  • Make decisions regarding safe work practices. These decisions can have significant consequences including bodily injury, as when deciding if and when to brace a scaffolding. (3)
Back to Top

Problem Solving
  • The tools or materials provided for a job are insufficient or unsuitable. Report the problem to the foreman to rectify the situation. (1)
  • An error has been made, such as underestimating the quantity of materials required to complete a job or task. Some loss of time or money may occur in fixing the problem, which may involve consulting with the foreman, obtaining more materials, modifying the plans or starting over. (2)
  • There are problems with work done by previous trades, for example a room that is not square. Choose among several solutions, ranging from leaving it as is or building a furring wall to correct the situation. Numerous criteria will need to be considered, such as the degree of error, the nature and function of the space under construction, and time/money required to implement each solution. (2)
Back to Top

Finding Information
  • Ask for and receive information from other tradespersons, lead hands, supervisors and other site personnel about routine matters related directly to work tasks. (1)
  • Read brochures about new product information or new technology that you may consider using. (1)
  • Consult specification books, safety manuals or Material Safety Data Sheets (MSDS) to locate specific information. (1)
  • An important piece of information is missing from the blueprint. Refer to the specifications manual, consult with a supervisor, or if a supervisor is unavailable, speak directly with the architect or engineer in order to continue working on that task. (2)
