Industry Glossary Term

Processing Capacity

The maximum volume of oil, gas, or fluids a facility can handle within a given timeframe. For subcontractors, it determines the pace and scale of your scope of work on site. Exceeding this limit causes bottlenecks that can delay schedules and trigger penalties.

Related Terms

Spud Date

Industry

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

Limited Notice To Proceed

Industry

An LNTP (Limited Notice to Proceed) authorises subcontractors to begin a defined scope of work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities up to a specified dollar limit. Work performed beyond that limit is at the subcontractor's own risk until full NTP is issued.

Tie-In

Industry

A tie-in is the physical connection of new pipeline or equipment to an existing operational system. For subcontractors, tie-in work often requires strict scheduling around shutdowns and may involve additional safety and permitting requirements. Scope changes during tie-ins can affect billing, so clear change-order terms are essential.

MEP (Mechanical, Electrical, and Plumbing)

Industry

Refers to the three core building systems subcontractors install and maintain on construction and industrial facility projects. MEP scopes are often divided among specialised trades, each holding separate contracts or working under a prime contractor. Understanding MEP divisions helps subcontractors define their scope, avoid overlap disputes, and price work accurately.

Transmission Line

Industry

A high-voltage power line that moves electricity over long distances between generation sources and distribution networks. Subcontractors often support transmission line projects through clearing, trenching, tower erection, and right-of-way maintenance work.

Work Order

Industry

A formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.
