The percentage of a technician's shift spent on hands-on productive work versus travel, waiting, or admin tasks. For subcontractors, low wrench time means billing inefficiencies and reduced daily output. Clients often track it to evaluate crew productivity on site.
Wrench Time
Related Terms
Demand Response
WorkforceA short-notice call-up system where operators request crews or equipment during peak production needs. Subcontractors on demand response agreements must mobilise quickly, often within hours. Rates are typically higher to compensate for the standby commitment.
Nonemployer Establishment
WorkforceA business that generates revenue but has no paid employees — typically a sole proprietor or owner-operator. Many field subcontractors and independent tradespeople operate this way. Statistics Canada tracks these firms separately in labour and industry data.
Dispatch
WorkforceThe process of assigning and deploying field crews or equipment to a job site. For subcontractors, dispatch timing affects mobilisation costs, crew scheduling, and billable hours. Clear dispatch records also support accurate invoicing and dispute resolution.
SPARK (Spreading Prosperity and Advancing Resilience With Knowledge)
WorkforceA federal initiative aimed at strengthening economic opportunity and business resilience for trades and service contractors. It supports workforce training, skills development, and financial stability programmes. Subcontractors may access funding or resources through SPARK to grow capacity and weather market downturns.
Independent Contractor
WorkforceA self-employed individual or company hired to complete specific work under contract, rather than as an employee. In field service, this covers most subcontractors supplying labour or specialised skills to operators and prime contractors. Independent contractors are responsible for their own taxes, insurance, and equipment.
Colocation
WorkforceWhen a subcontractor embeds personnel or equipment at a client's site for an extended engagement. This reduces mobilisation costs and improves response time for ongoing work. It is common on large construction or production sites requiring continuous support.
