Daily oil & gas and construction news for subcontractors

Industry Glossary Term

Call for Interest

A formal notice from an operator or prime contractor inviting subcontractors to express interest in upcoming work. It is not a binding tender but helps owners build a qualified vendor list. Responding early can position your company for the actual bid process.

Related Terms

Digital Twin

Industry

A virtual replica of physical equipment or a facility, updated with real-time field data. Subcontractors may use it to plan maintenance, anticipate failures, and align fieldwork with current asset conditions. It reduces surprises on-site and supports more accurate scope planning.

Portable Crusher

Industry

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.

Tunnel Portal

Industry

The open entrance and exit points of a tunnel where underground meets surface operations. For subcontractors, portals are critical mobilisation zones for equipment, crews, and material staging. Access, congestion, and safety controls at portals directly affect your crew's productivity and schedule.

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.

Straddle Plant

Industry

A midstream processing facility installed along an existing pipeline to extract natural gas liquids like propane and butane. Subcontractors are frequently mobilised for construction, maintenance, and turnaround work at these sites. Work scopes often include compression, refrigeration, and fractionation system servicing.

Below-Grade

Industry

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.
