Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Dual-Class Share Structure

A 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.

Related Terms

Lean Construction

Industry

A project delivery approach that eliminates wasted time, materials, and labour on job sites. Subcontractors use lean methods to tighten scheduling, reduce idle crew time, and improve handoffs between trades. It often involves short-interval planning tools like the Last Planner System.

Drill-And-Blast

Industry

A 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.

Development Sanction

Industry

The formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.

EIA (Energy Information Administration)

Industry

A U.S. federal agency that publishes energy data, forecasts, and market reports. Subcontractors use EIA reports to track oil and gas price trends and anticipate shifts in project demand. Monitoring EIA data helps field service companies time bids and resource planning.

PWHT (Post-weld Heat Treatment)

Industry

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

Headframe

Industry

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.
