PPA (Power Purchase Agreement)

A shared 3D digital model of a construction project that contains structural, mechanical, and site data. Subcontractors use it to coordinate work sequences, avoid clashes with other trades, and verify installation specs before mobilising. Access to the BIM model is often required before entering a worksite.

A one-way valve or flap gate that allows water to drain freely but prevents backflow from rising tides or high water levels. Subcontractors working on coastal or waterfront sites must account for tide gate locations when planning drainage, excavation, or utility work. Ignoring these structures can cause flooding, schedule delays, and scope changes.

A machining process that removes material from a flat surface to restore or achieve precise tolerances on equipment components. Subcontractors are often mobilised to perform surface milling on wellheads, flanges, or structural steel on-site. Proper equipment certifications and dimensional records are typically required for handover documentation.

Any work or structure located below the finished ground surface, such as buried pipelines, foundations, or conduits. Subcontractors must account for added costs like shoring, dewatering, and confined space compliance. Scope changes below-grade often trigger change orders due to unforeseen soil or utility conditions.

A peaking facility is an energy plant activated only during periods of high demand, such as extreme cold snaps. For subcontractors, these sites generate short-notice, high-intensity work orders requiring rapid crew mobilisation. Expect compressed timelines and premium billing opportunities during activation periods.

A large-scale battery installation that stores and dispatches electrical power on remote or off-grid job sites. Subcontractors may be hired to install, commission, or maintain these units alongside diesel generators or solar arrays. Familiarity with high-voltage systems and OEM safety protocols is typically required.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
