Begin Actual Construction

A defined area containing multiple wells and associated surface infrastructure operated as a single development. Subcontractors often mobilise across an entire wellfield under one master contract, servicing several wellsites in rotation. Scope, travel, and logistics planning should account for the full wellfield footprint.

A long-term contract where a buyer agrees to purchase electricity from a generator at a fixed price. For subcontractors, PPAs on large sites can affect whether temporary or permanent power infrastructure is in scope. Understanding site power arrangements helps clarify mobilisation costs and equipment requirements.

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

A Canadian-designed nuclear reactor that uses heavy water as a moderator and coolant. Subcontractors working on maintenance or upgrades face strict nuclear regulatory compliance and specialised certification requirements. Expect rigorous site access controls, radiation safety training, and detailed documentation standards.

Raw, unprocessed natural gas delivered to a processing plant or facility as the primary input. For subcontractors, feed gas specifications determine the scope of compression, treating, and handling work on site. Changes in feed gas composition can trigger scope variations and affect your contract terms.

An ownership arrangement where a First Nations group holds a financial stake in a project or company. Subcontractors may be required to include an equity partner to win work on certain corridors or project areas. This affects bidding structure, profit-sharing, and how contracts are awarded.
