Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

In-Situ

Work performed on-site without removing equipment or materials from their installed position. Subcontractors are often mobilised specifically for in-situ repairs, inspections, or testing. Scope and billing should clearly reflect the fixed work location.

Related Terms

Integrated Project Delivery (ipd)

Industry

A project delivery model where owners, contractors, and subcontractors share contracts, risks, and rewards from early design through completion. Subcontractors are brought in earlier than traditional models, giving more input on planning and scheduling. Compensation is often tied to collective project outcomes rather than individual scope performance.

E&I (Electrical and Instrumentation)

Industry

A trade discipline covering the installation, maintenance, and commissioning of electrical systems and process instrumentation on industrial sites. Subcontractors in this scope typically hold specialised certifications and work across upstream, midstream, and construction projects. E&I scopes are commonly tendered separately from mechanical or civil work.

Spud Date

Industry

The date when drilling begins on a new well. Marks the start of drilling operations.

Clastic Reservoir

Industry

A rock formation made of compacted sediment fragments — like sandstone or conglomerate — that holds oil or gas. Most drilling and completions work in Western Canada targets clastic reservoirs. Knowing the formation type helps crews anticipate ground conditions and equipment requirements.

Gigafactory

Industry

A large-scale manufacturing facility producing batteries or energy components, often for EV or renewable projects. These sites generate major subcontracting opportunities in electrical, civil, and mechanical trades. Expect large crew mobilisations, tight schedules, and industrial construction workflows.

Third-Party Contracting

Industry

An arrangement where a primary contractor hires an outside company to perform specialised work on a project. For subcontractors, this defines your position in the contracting chain and affects payment terms, liability, and site access. Knowing your tier level helps clarify who you invoice and who manages your compliance requirements.
