Additional informationWorking with Others

Depending on the situation, construction electricians work with a co-worker or in a team of construction electricians assigned to complete installations in a particular area. Large construction sites involve the services of several other building trades. Conflicting priorities occur; however, all have a stake in working safely and efficiently. Construction electricians work primarily with other construction electricians but may also interact with a wide variety of workers including apprentices, supervisors, owners' representatives, architects, engineers, inspectors and suppliers.

Continuous Learning

Because the electrical code is updated regularly, construction electricians are expected to continue to learn and become familiar with changing code requirements. They must also keep up-to-date with changes in technology, such as computer controls or programmable logic controllers (PLCs). Also, fibre optics and data cables are becoming more widely used and trained installers are in demand. Construction electricians enroll in scheduled classes offered by the union, employers, wholesalers, manufacturers or distributors and may also take continuing education classes at their own expense. Some written material is available for self-study.
