Industry Glossary Term

MEP (Mechanical, Electrical, and Plumbing)

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.

Related Terms

Frac Campaign

Industry

A scheduled series of hydraulic fracturing operations across multiple wells or stages within a defined period, representing a concentrated burst of work that subcontractors must plan for with adequate crew, equipment, and supply chain capacity. For field service companies, winning a spot in a frac campaign can mean weeks of steady, high-volume work but also demands tight mobilisation timelines and the ability to scale up quickly.

Acreage Position

Industry

The total land or mineral rights an operator holds for exploration or production. A large acreage position often signals sustained work programmes and long-term subcontractor demand. It helps field service companies forecast pipeline opportunities in a region.

Rig Release

Industry

The formal point when a drilling rig is demobilised and the operator ends the rig contract. For subcontractors, it signals the close of associated scopes of work and triggers final invoicing. Crew demob, equipment retrieval, and close-out documentation should begin immediately.

Lower 48

Industry

Refers to the contiguous United States, excluding Alaska and Hawaii. For subcontractors, it defines a common work jurisdiction with distinct regulatory, tax, and labour rules from Canadian or Alaskan operations. Mobilisation costs and compliance requirements differ significantly when crews cross into or out of this region.

Bcf/d (billion Cubic Feet Per Day)

Industry

A measure of natural gas production or pipeline throughput volume. Higher BCF/d figures on a project typically signal larger-scale operations requiring more field crews and equipment. Subcontractors can use this metric to gauge the scope and duration of potential work.

Liquefaction

Industry

The process of converting natural gas into liquid form (LNG) by cooling it to extreme temperatures for storage and transport. Subcontractors supporting liquefaction facilities must meet strict safety and technical certifications. Work scopes often include maintenance, insulation, and cryogenic system servicing.
