Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Material Takeoff

A detailed list of all materials, quantities, and specifications needed to complete a scope of work. Subcontractors use it to prepare accurate bids and avoid costly shortages or overruns in the field.

Related Terms

Paid-Up Lease

Industry

A lease where all rental payments are made upfront, with no ongoing delay rentals required to keep it active. For subcontractors, this signals stable, long-term site access without mid-contract tenure disruptions. Work scopes on paid-up leases are less likely to be suspended due to expiry pressure.

Heat Tracing

Industry

A system of electric cables or steam lines wrapped around pipes to prevent freezing or maintain process temperatures. Subcontractors are often hired to install, inspect, and commission these systems during turnarounds or new construction. Common in cold-climate facilities handling water lines, instrumentation, and process piping.

Rare-Earth Elements

Industry

A group of 17 metallic minerals critical to manufacturing motors, sensors, and electronics used in oilfield and construction equipment. Supply chain disruptions can affect equipment availability and drive up costs for field service operators. Subcontractors should monitor REE-related procurement delays when planning equipment-intensive scopes.

Rigging

Industry

The equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.

Diverging Diamond Interchange

Industry

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.

Lattice Boom

Industry

An open-framework steel crane arm made of welded triangular sections, used for heavy lifts on oil and gas or construction sites. Subcontractors must verify lift plans and operator certifications before mobilising lattice boom cranes. Daily rates and rigging crew requirements are typically higher than hydraulic boom alternatives.
