Glossary

Apprenticeship

A structured, multi-year training program combining paid on-the-job work under experienced journeymen with classroom instruction, and the primary way skilled trades such as electricians are produced.

Commissioning

The final process of testing, integrating, and proving every system in a facility under realistic conditions before it carries live load, performed by specialists whose scarcity can gate the energization date.

Critical path

The sequence of dependent tasks that determines the shortest possible duration of a project; in data center builds it typically runs through specialized electrical, mechanical, and commissioning work.

Critical-facilities technician

A skilled operations worker who maintains and monitors a data center's power and cooling systems around the clock, often drawn from military, industrial, or technical-college backgrounds.

Journeyman

A tradesperson who has completed an apprenticeship and is qualified to perform the full scope of their trade independently, as distinct from a still-training apprentice.

Method of procedure

A scripted, reviewed sequence of steps for performing a significant task on live systems, used in operations to ensure maintenance follows a safe, planned process rather than improvisation.

Project labor agreement

A pre-hire arrangement negotiated before construction that sets wages and dispute procedures for all trades on a job and commits unions to supply the workforce and avoid work stoppages.

Traveler

A skilled worker who relocates temporarily from another region to work a specific project, often supported by per diems and housing, allowing a metro to host a project larger than its local workforce could staff.
