Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Frontier Exploration

Exploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.

Related Terms

Vertical Mast Lift

Industry

A type of aerial work platform that raises personnel or materials straight up on a single mast column. Commonly used in confined or tight job sites where boom lifts cannot manoeuvre. Subcontractors must verify operator certifications and load ratings before mobilising.

Turnkey

Industry

A contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.

Secondary Stress

Industry

Indirect mechanical stress that develops in structures or piping due to thermal expansion, settlement, or equipment movement. Unlike primary stress, it isn't caused by direct applied loads. Subcontractors must account for it during installation and inspection to avoid material fatigue and warranty disputes.

Grade Separation

Industry

A crossing where a road, pipeline, or utility passes over or under another route using a bridge or culvert. Subcontractors must account for grade separations when planning equipment moves and material hauls. Permits and escort requirements often apply when loads approach clearance limits.

Appraisal Well

Industry

A well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.

Utility Relocation

Industry

The process of moving existing underground or overhead utilities — such as gas lines, water mains, or electrical conduits — to accommodate new construction or pipeline work. Subcontractors are often hired specifically for this scope, which requires utility locates and coordination with municipal or utility owners. Delays in relocation can directly impact your crew's mobilisation schedule and project milestones.
