A unit measuring one megawatt of electrical power consumed or produced over one hour. Subcontractors encounter MWh when billing for generator rentals, temporary power supply, or energy-intensive equipment on remote sites. It also appears in green energy projects where field crews install or service solar, wind, or battery storage systems.
Mwh (megawatt-Hour)

Dynamic Line Rating
IndustryA real-time method of calculating the maximum safe current capacity of a power line based on actual weather and load conditions. Unlike fixed ratings, it allows more power to flow when conditions permit. Field crews may encounter adjusted work protocols near energised lines as ratings shift throughout the day.
Full Displacement Pile
IndustryA foundation pile driven or screwed into soil without removing material, pushing ground laterally to create a tight fit. Common in oil and gas facility and construction site foundations. Subcontractors should confirm soil displacement specs early, as ground conditions directly affect equipment selection and crew scheduling.
MRP (Materials Requirements Planning)
IndustryA scheduling system that calculates what materials are needed, in what quantities, and when. Subcontractors use it to avoid shortages or excess stock on job sites. It ties material orders directly to project timelines and scopes of work.
Reinforcing Bar (rebar)
IndustrySteel bars embedded in concrete to add tensile strength in foundations, structures, and infrastructure builds. Subcontractors handling rebar must account for material costs, placement labour, and tie wire in their bids. Improper installation can trigger costly rework and inspection failures.
Critical Minerals
IndustryMinerals deemed essential to national economies and energy transition, such as lithium, cobalt, and rare earths. Extraction and processing projects for these materials are driving significant new field service demand across Canada. Subcontractors with mining or remote site experience are well-positioned to pursue this growing work.
Metallographic Replication
IndustryA 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.
