Learn About Abilities

Updated Mar 05, 2021

Timber scalers measure the volume of sample truckloads of timber, decked trees or single trees to provide reliable estimates of harvested wood. Volume measurements are done to report to the government on what was delivered to a mill and to determine how much the company owes to loggers (for cutting the timber) and to the provincial government (for timber dues). Most mills have a timber quality program in place to grade the loggers on the utilization of the timber logged.

Duties and responsibilities vary somewhat from one job to another. For example, some companies expect scalers to buck (cut) tree length logs into usable lengths before scaling them. Other companies, the wood is delivered as cut to length by the loggers. In general, however, scalers:

  • Measure log lengths and diameters using scale sticks and logger tapes
  • Use handheld computers or tally sheets to record measurements in the field and later upload or enter data into computer programs
  • Estimate the loss of volume caused by defects and tree shape
  • Identify cull logs containing excessive amounts of unsound wood
  • Calculate the difference between gross volume and unusable volume to obtain usable volume
  • Keep records of the amount, condition and species of each load of logs scaled

Industry timber scalers are subject to periodic checks by the provincial government to ensure measurements are accurate.

Working Conditions
Updated Mar 05, 2021
  • Strength Required Lift up to 10 kg

Timber scalers work outdoors generally for an 8-hour day, with some overtime required when there is sufficient daylight. Depending on the mill, scalers can be busy most of the year except for spring break up. However, busy season for some mills is only during fall and winter months.

Most scaling is done in mill yards. However, some bush scaling is required to determine volumes in logging cut blocks.

This work requires standing and bending for long periods of time. Safety precautions and safety equipment are required to reduce the risk of injury when working around large equipment, possibly operating a chainsaw and working on decks of logs, particularly when they are slippery.

Traits & Skills
Updated Mar 05, 2021

Timber scalers need:

  • Physical stamina
  • The ability to work in cold conditions
  • Numerical and computer skills to calculate volumes and keep accurate records

They should enjoy taking responsibility for projects that require planning and decision making, having clear rules and organized methods for their work and performing precision tasks.

Educational Requirements
Updated Mar 05, 2021
  • Minimum Education Varies

There are no standard minimum educational requirements for timber scalers. However, they must be able to recognize different tree species and may be required to have a minimum Grade 10 education in order to attend training courses. Those who are self-employed need business management skills.

Employers generally prefer to hire people who have experience in the logging industry or related post-secondary education in forestry.

Scalers must be certified by the provincial government. The Hinton Training Centre offers 5-day provincial certification courses for timber scalers at the centre, and through Portage College in Lac La Biche. The college may also offer 10-day courses, which will cover the same course content but allow more time for hands-on experience. Graduates who pass an exam are certified as Alberta permitted scalers.

For information about longer forestry certificate and diploma programs that include instruction for Alberta scaler certification, see the Forest Technician and Forest Technologist profiles.

Employment & Advancement
Updated Mar 05, 2021

Timber scalers are employed by wood processing facilities such as sawmills and woodland contractors.

Experienced scalers can move into other positions in mills, advance to supervisory positions or become self-employed contractors. Post-secondary education in forestry may improve advancement opportunities.

Timber scalers are part of the larger 2011 National Occupational Classification 2223: Forestry technologists and technicians. In Alberta, 90% of people employed in this classification work in the following industries:

The employment outlook [pdf] in this occupation will be influenced by a wide variety of factors including:

  • Time of year (for seasonal jobs)
  • Trends and events affecting overall employment (especially in the industries listed above)
  • Location in Alberta
  • Employment turnover (when people leave existing positions)
  • Occupational growth (when new positions are created)
  • Size of the occupation

In Alberta, the 2223: Forestry technologists and technicians occupational group is expected to have a below-average annual growth of 1.1% from 2019 to 2023. In addition to job openings created by employment turnover, 20 new positions are forecasted to be created within this occupational group each year.

NOC groups often include several related occupations. Although there is labour market data for the larger NOC group, this occupation makes up only a part of that group. It means data for this occupation may be different than the data shown. For example, only some of the new positions to be created will be for this occupation. It also applies to other data for the NOC group such as number of people employed.
