Grid congestion occurs when electrical transmission lines carry more power than they can handle, causing bottlenecks. For subcontractors, it can delay grid-tied project energisation and push back commissioning milestones. Remote site work may shift to temporary generation until congestion is resolved.

Related Terms
Vam Connections
IndustryPremium threaded pipe connections used in oil and gas drilling and completion operations. Subcontractors handling, installing, or inspecting VAM connections must follow strict torque specs and handling procedures. Improper makeup can result in costly downhole failures and liability exposure.
Abandonment
IndustryThe regulated process of permanently closing a well or facility at end-of-life. Subcontractors are often hired for plugging, reclamation, and site cleanup scopes. Abandonment projects can be steady work but require strict compliance with provincial regulations.
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.
Deep Foundation
IndustryA structural support system that transfers building loads to stable soil or rock far below the surface, typically using piles or caissons. Subcontractors are often mobilised for drilling, pile driving, or concrete work on these scopes. Expect specialised equipment requirements and strict geotechnical inspection protocols on site.
Dual-Class Share Structure
IndustryA corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.
Cementing
IndustryThe process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.
