They must take responsibility for the problem, apologize where needed, and use persuasion and negotiating skills to make the necessary corrections in as cost effective a way as possible. (2)
  • May hoist or deliver units, especially heavy or awkward shapes, to the area of installation only to find out that it can't be moved into place or doesn't fit the intended opening. Double checking of measurements of the load compared to the size of the installation opening and delivery path may result in adjustments to the load or opening before hoisting. In some cases, computer software can be used offsite to simulate practical problems and different solutions can be tried effortlessly. (3)
  • May encounter problems with other trades when priorities conflict. Unit installation on the third floor of a building will make stone work beneath unsafe. Workers from different trades coordinate work tasks. Glaziers find alternate tasks or negotiate trade offs to prevent escalation of disputes that may involve supervisors. (3)
  • May discover that measurements or elements have been omitted from drawings or are incorrectly placed. They constantly translate two dimensional blueprint specifications into three dimensions and relate new construction with existing structures. By visualizing the parts, glaziers can identify and correct errors early in the process. (3)
Decision Making
  • Decide what equipment to use on a job, such as whether to use a ladder or a scaffold, based on the size and elevation of a project. (1)
  • Decide whether to do a job independently or arrange for assistance. (2)
  • Decide on the sequence and timing of many tasks such as whether to construct a frame before or after the doors have arrived. (2)
  • Decide a method to determine the correct side in order to install a sealed unit containing two lights. "Low E" coating is used to deflect the sun and must be placed on the correct side. An error in installation could result in the unit failing. Glaziers have several methods of determining the correct side, for example, using a flame to distinguish the light reflecting a discoloured flame. (2)
  • Make numerous safety decisions such as whether to proceed with a job on a windy day, or whether to put up barricades or allow public access to a work area or whether equipment is safe to operate. (3)
  • Decide which is the most cost efficient and safe method to move heavy or awkward loads. They consider accessibility, load capacity, labour and time involved. (3)

Job Task Planning and Organizing

Glaziers' work schedules are planned in response to customers' needs. Although they organize and decide on the sequence of tasks, glaziers' priorities are generally decided in consultation with supervisors and others working on the contract or project. Planning and ordering of tasks are key skills for efficiency. Glaziers' work must be coordinated with the work of many others including contractors, other building trades, draftspersons, estimators, foremen, suppliers and delivery personnel. Weather is also an important factor and glaziers adjust their schedules in response to wind, precipitation and cold. (3)

Significant Use of Memory
  • Remember many common product numbers.
  • Remember the names, phone numbers and locations of frequently used suppliers and customers.
  • Remember details of specifications for a particular job during the time they are working on that job.
Finding Information
  • Refer to suppliers' lists to find parts and materials required. (1)
  • Consult glass and framing parts and installation manuals for information on procedures and prices. (1)
  • May phone a supplier or manufacturer to find out about a product such as a new sealant. (2)
  • Consult with a manager or others working in the industry with regard to hard to locate parts or for advice about alternative materials. (2)
  • May access a reference library containing texts on layout, hoisting and rigging and other related topics. (3)
Digital technology
  • On some job sites, blueprints are accessed online which involves navigating a number of screens to find the right detail drawing. CAM programs may be used in fabrication shops. (2)

Working with Others

Glaziers may work independently or with partners or apprentices depending on the type of work they are performing. For example, frame fabricators often work alone while constructing frames, while installers will usually work with a partner or apprentice while installing windows. Glaziers must coordinate their work with many other co-workers, trades and suppliers. They see themselves as members of a team who work together to provide a quality service or product. Some glaziers supervise the work of apprentices and other journeypersons on larger jobs.

Continuous Learning

Glaziers frequently learn about new products and materials such as a new line of metal for framing or a new high performance window. They find out about these products by referring to brochures or manuals from suppliers and by using them on the job. Occasionally, their employer may send them for training by the manufacturer in how to use or install a new product. Glaziers also attend courses and orientations on safety procedures and the operation of equipment such as a swing stage or scissor lift. Union training plans also offer upgrading on topics such as layouts, rigging and welding.
