When 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.

Knowledge Continuity
WorkforceThe practice of preserving critical site knowledge when crews rotate or contracts change hands. It ensures incoming workers understand site-specific procedures, hazards, and client expectations without starting from scratch. Poor knowledge continuity leads to rework, safety gaps, and damaged client relationships.
Utilisation Rate
WorkforceThe percentage of available hours that crews or equipment are actively billable to a client. A low utilisation rate signals idle resources eating into margins. Subcontractors track this metric to assess workforce efficiency and bid competitiveness.
Floater
WorkforceA skilled tradesperson or technician not assigned to a fixed crew or project, deployed where needed on short notice. Subcontractors often bill floaters at a premium rate due to their flexibility and quick availability.
CES (Current Employment Statistics)
WorkforceA monthly U.S. Bureau of Labour Statistics survey tracking employment, hours, and earnings across industries. Field service subcontractors use CES data to benchmark wage rates and spot labour market trends. It helps inform bid pricing and crew cost projections in competitive markets.
Shoulder Season
WorkforceThe transitional period between peak and slow seasons when project volumes drop and scheduling becomes unpredictable. Subcontractors often face reduced call-outs, crew utilisation gaps, and tighter margins during these windows. Common in oilsands and construction work between summer and winter campaigns.
Geofencing
WorkforceA virtual boundary set around a job site that triggers automatic alerts when workers or equipment enter or leave. Subcontractors use it to verify on-site attendance, automate timekeeping, and support accurate billing. It also helps clients confirm crew deployment without manual check-ins.
