Industry Glossary Term

IFB (Invitation for Bids)

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.

Related Terms

SPMT (Self-propelled Modular Transporter)

Industry

A multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.

LWD (Logging While Drilling)

Industry

A drilling technique that collects formation data in real time as the bit advances. Subcontractors providing LWD services operate specialised downhole tools that transmit data to surface during the drill run. Mobilisation windows are tight, so crews and equipment must be ready on short notice.

Rig Utilization

Industry

The percentage of time a rig is actively working versus sitting idle. For subcontractors, high rig utilisation means steady billable hours and predictable revenue. Low utilisation signals contract gaps that strain cash flow and crew retention.

Medium Voltage Transformer

Industry

A device that steps electrical voltage up or down within the 1 kV to 35 kV range on industrial job sites. Subcontractors often work around these units when installing temporary power or connecting equipment. Strict lockout/tagout and electrical certification requirements apply near this equipment.

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.

LNG (Liquefied Natural Gas)

Industry

Natural gas cooled to -162°C to become liquid for easier transport and storage, creating specialized work opportunities for subcontractors in cryogenic equipment maintenance, pipeline construction, and terminal facilities that require specific safety certifications and cold-weather expertise.
