Steel Erection

A mobile machine that breaks down rock, concrete, or aggregate on-site, eliminating haul-off costs. Subcontractors often supply or operate these units under equipment rental or crushing contracts. Commonly used in pipeline trenching, site prep, and demolition scopes.

A drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.

A pressurised pipeline system that transports carbon dioxide, typically for carbon capture and storage (CCS) projects or enhanced oil recovery (EOR). Subcontractors may be engaged for construction, inspection, or maintenance under strict pressure and corrosion control requirements. Specialised welding certifications and material handling protocols are commonly required for this work.

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.

The process of producing and managing saltwater solutions used in well completion, workover, and drilling operations. Subcontractors may be engaged for fluid handling, storage, transport, or disposal services. Scope can vary widely, so confirm fluid specifications and disposal requirements before mobilising.

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.
