Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Crane Mats

Large interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.

Alternative Delivery Models

Industry

Contracting arrangements beyond traditional lump-sum or day-rate structures, such as alliance, integrated project delivery, or performance-based contracts. These models shift how subcontractors are engaged, paid, and held accountable for outcomes. Understanding them helps field service firms assess risk, pricing strategy, and scope responsibilities before signing.

Multi-Trade Pipeline

Industry

A project requiring multiple specialised trades — such as welders, pipefitters, and electricians — deployed in sequence or simultaneously. Subcontractors must coordinate closely to avoid schedule conflicts and delays. Winning work on these projects often requires demonstrating multi-discipline capacity to the prime contractor.

Infrastructure Build Cycle

Industry

The period spanning initial site development through to project completion, during which subcontractors see peak demand for civil, mechanical, and electrical trades. Work volumes are highest in early and mid-cycle phases. Subcontractors should plan crew capacity and equipment availability around these predictable surges.

Utility-Scale Storage

Industry

Large battery or energy storage systems that supply power to grids or remote job sites. For subcontractors, these projects involve specialised electrical, civil, and commissioning crews. Work often includes foundation pours, equipment installation, and grid tie-in under strict utility standards.

Transmission Corridor

Industry

A designated strip of land reserved for pipelines, power lines, or utility infrastructure. Subcontractors must obtain right-of-entry approvals before mobilising equipment or crews within these zones. Work inside corridors often triggers additional environmental and regulatory compliance requirements.

PPA (Power Purchase Agreement)

Industry

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.
