A non-destructive field technique used to examine the microstructure of in-service metal components without removing them. Technicians apply a softened acetate film to a polished surface, then analyse the hardened impression under a microscope. Subcontractors use it to assess weld integrity, creep damage, or material degradation on piping and pressure vessels.

Drill-And-Blast
IndustryA ground excavation method where holes are drilled into rock, then loaded with explosives and detonated. Subcontractors on these scopes typically require certified blasters and strict compliance with provincial explosives regulations. Expect tight sequencing with other trades and potential site shutdowns during blast windows.
Hot Shot
IndustryExpedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.
Frac Fleet
IndustryA complete set of hydraulic fracturing equipment deployed together at a well site, including pumps, blenders, and support units. For subcontractors, a frac fleet mobilisation often triggers large, time-sensitive labour and equipment contracts. Knowing fleet size helps you scope crew requirements and forecast workload duration.
Substrate
IndustryThe base material or surface that a coating, lining, or treatment is applied to, such as steel pipe, concrete, or wood. Subcontractors must assess substrate condition before starting surface prep or application work. Poor substrate quality can affect adhesion, warranty, and job acceptance.
Spud Date
IndustryThe date when drilling begins on a new well. Marks the start of drilling operations.
Gigafactory
IndustryA large-scale manufacturing facility producing batteries or energy components, often for EV or renewable projects. These sites generate major subcontracting opportunities in electrical, civil, and mechanical trades. Expect large crew mobilisations, tight schedules, and industrial construction workflows.
