Job Task Planning and Organizing
  • Boilermakers' job task planning and organizing responsibilities are dependent on their work setting (shop or construction). In some cases, boilermakers may be given a project to complete and a technical drawing to follow. They decide upon the production sequence and task allocations in conjunction with their supervisor. Time management is determined by the project timelines. In other cases, boilermakers are given detailed instructions by their foreperson, which often include the daily production schedule and assigned tasks (although the former can be determined jointly at the pre-job planning meeting). The day-to-day organizational requirements of the job are very dependent upon the projects involved. In some situations, identical parts are being produced or identical tasks being performed, making each day repetitive and easy to plan. In other situations, different tasks are being performed or a variety of products being made or repaired which presents a number of planning challenges, including frequent interruptions. Sequencing, scheduling and coordinating are very important when several trades are involved in a project. Effective planning is especially important if the worksite cannot safely support several individuals working at the same time. Any boilermaker can be called upon to serve as a working foreperson if there are six or less boilermakers in a crew. A working foreperson has additional planning responsibilities such as organizing the tasks of the crew as well as other tradespeople involved in the job. A working foreperson determines daily production schedules, sequences tasks, coordinates work schedules across trades, and ensures timelines are met. When working forepersons plan and organize others, they consider the number of workers the site can safely accommodate at any one time, optimal use of person hours for all trades involved, job deadlines, task sequencing, the skill mix of crew members, and numbers of workers assigned to the crew. Planning and organizing others is not a primary responsibility of the occupation, but the position of working foreperson is important when assumed. (3)

Decision Making
  • Decide at the phase hazard analysis stage whether a two-way radio is necessary for critical lifts or if hand signals can be used. (1)
  • The other workers you are working with lack the skills to do a job safely and effectively. Decide whether to take the time required to explain how improvements could be made or to refer the situation to a supervisor. (1)
  • An equipment error has been identified, such as a bracket attached unevenly, which does not affect the functionality of the structure. Decide whether to repair it, considering such factors as deadlines and the potential reaction of the client. (2)
  • Sub-standard work has been discovered in a commercial setting or in the field. Decide whether to correct the problem, notify an authority or determine who is responsible and why the problem occurred. (2)
  • Decide whether to refuse a job that you consider is potentially dangerous. (3)
Back to Top

Problem Solving
  • The job is supposed to begin on a specific date but the worksite has not been prepared. Determine what job tasks may be addressed in the interim to ensure that deadlines will be met. (1)
  • The appropriate tools are not available to complete a task effectively. Determine what tools are necessary and custom fabricate them (e.g., jigs, dog and wedge). (2)
  • Deal with tight timelines imposed by job conditions. Assess the assigned task to determine a more feasible timeframe. Then share this information with supervisory staff who determine if additional personnel should be assigned or overtime shifts implemented. (2)
  • There are potentially hazardous job conditions (e.g., fly ash, asbestos, arsenic) that require a specific response. Assess the situation to determine what action should be taken and then implement the solution (e.g., choose appropriate safety equipment, isolate the area, call insulators to strip asbestos). (2)
  • The blueprints (created by draftspersons or engineers) do not accurately reflect the reality of a situation. Determine what changes are necessary and make recommendations to the foreperson for consideration by engineering staff. (2)
  • Many tradespeople are required to complete a job at a worksite that can only safely accommodate a limited number of tradespeople at any given time. Sequence tasks within your own team to complete the work on schedule. Also coordinate with other trades (e.g., electricians), considering such factors as safety and the optimal use of person hours across trades. (3)

  • Locate information in a technical handbook regularly to review procedures, mathematical equations, specifications, symbols and equipment. (1)
  • Obtain information on safe work practices from co-workers and supervisors during safety toolbox meetings. (1)
  • Refer to a collective agreement to verify pay rates and worker rights. (1)
  • Consult with quality control officers, engineers and/or draftspersons to get information about blueprints and design. (1)
  • Refer to a catalogue to get a part number or the name of a piece of equipment. (1)
