Brownfield Site

A road interchange design where traffic briefly crosses to the opposite side of the road between two intersections. Subcontractors hauling heavy equipment or oversized loads must account for altered lane patterns and potential permit route restrictions. Plan site access carefully, as DDI layouts can complicate convoy movements and GPS routing.

Backreaming is the process of enlarging a pilot borehole by pulling the reamer back through while rotating. Subcontractors are often mobilised specifically for this phase on HDD (Horizontal Directional Drilling) projects. Billing is typically tied to footage reamed or hourly rig time.

A formal document issued by an operator or prime contractor soliciting fixed-price bids for a defined scope of work. Subcontractors must submit pricing by a set deadline, with contracts typically awarded to the lowest qualified bidder. Review the technical specs and site conditions carefully before submitting your number.

A trenchless pipe rehabilitation method where a resin-saturated liner is inserted into a damaged pipe and hardened in place. Subcontractors typically provide specialised crews, inversion or pull-in equipment, and UV or steam curing systems. Common in municipal, oil and gas, and industrial pipeline maintenance scopes.

Refers to energy or infrastructure projects large enough to supply power or resources to the grid or regional networks. For subcontractors, these projects mean longer mobilisations, larger crew requirements, and extended contract durations. Expect stricter compliance obligations and more layers of prime contractors to navigate.

Planned work that restores or extends the life of major assets, such as facilities or equipment. For subcontractors, these projects are typically larger in scope and budget than routine maintenance. They often require formal tendering, detailed scopes of work, and milestone-based billing.

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.
