Industry Glossary Term

CMMS (Computerized Maintenance Management System)

Software used to schedule, track, and document equipment maintenance and work orders on job sites. Subcontractors often must log completed maintenance tasks directly into a client's CMMS. Accurate entries protect you during audits and support invoicing for billable maintenance work.

Related Terms

Gas-Directed Drilling

Industry

A drilling approach where well placement decisions are guided by real-time gas readings from formation data. Subcontractors should expect frequent operational pauses for data evaluation and possible scope changes. Mud logging and wellsite geology crews are typically in high demand on these programmes.

NUCA (National Utility Contractors Association)

Industry

A U.S. trade association representing underground utility and excavation contractors. For subcontractors, membership signals credibility and provides access to training, advocacy, and industry standards. Useful when bidding on American utility projects requiring recognised affiliations.

HVDC (High-voltage Direct Current)

Industry

A power transmission system that moves large amounts of electricity over long distances using direct current. Subcontractors may encounter HVDC infrastructure on remote energy projects, pipeline corridors, or renewable tie-in work. Specialised certifications and safety protocols are typically required before working near HVDC lines or converter stations.

Preferred Vendor Program

Industry

A formal arrangement where a general contractor or operator pre-qualifies subcontractors for priority work access. Approved vendors are typically offered first right of refusal on new projects. Getting listed can mean steadier work volume but often requires meeting strict safety, insurance, and pricing criteria.

Load Growth

Industry

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

PAC (Polyanionic Cellulose)

Industry

A water-soluble polymer additive used in drilling fluids to control fluid loss and stabilise boreholes. Subcontractors handling mud systems must store and mix PAC carefully, as improper use affects drilling performance. It is commonly specified in drilling programmes, so field crews should follow the mud engineer's exact dosage instructions.
