Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Derivative Goods

Products created by processing or transforming raw materials supplied under a contract, such as fabricated components or treated fluids. Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.

Related Terms

Liquefaction Facility

Industry

A plant that cools natural gas to -162°C, converting it into LNG (Liquefied Natural Gas) for storage and transport. Subcontractors are commonly engaged for construction, maintenance, and instrumentation work at these sites. Expect strict safety certifications and specialised cryogenic equipment handling requirements.

Acre-Feet

Industry

A volume measurement equal to one acre of surface area filled one foot deep, roughly 1,233 cubic metres. Common in water management contracts for tailings ponds, frac water storage, and site remediation. Subcontractors may be scoped and billed based on acre-feet of material moved or treated.

Punching-Shear Failure

Industry

A structural failure where a concentrated load punches through a slab or foundation, creating a cone-shaped break. Subcontractors must watch for this risk when positioning heavy equipment on concrete pads or temporary platforms. Undetected, it can cause sudden equipment collapse and serious site liability.

Mission Critical

Industry

Describes any task, system, or equipment whose failure would halt operations or create serious safety risks. For subcontractors, mission critical work often carries stricter response times, higher liability, and tighter documentation requirements.

Load Growth

Industry

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

Lithium-Bearing Brine

Industry

Subsurface saltwater containing dissolved lithium, extracted from formations during drilling or dedicated mining operations. Subcontractors may encounter it on fluid handling, well servicing, or evaporation pond construction contracts. Demand for lithium is driving new project activity across western Canada and the Prairies.
