Industry Glossary Term

GPR (Ground-penetrating Radar)

A non-destructive scanning method that detects buried utilities, pipes, and subsurface anomalies before excavation begins. Subcontractors use GPR to reduce strike risk and meet dig-permit requirements on job sites. Many clients now require GPR clearance as a condition of mobilisation.

Related Terms

Wastewater Injection

Industry

The process of pumping produced water or other fluid waste deep into underground formations for disposal. Subcontractors operating injection pumps or wellbore equipment must meet strict provincial and federal disposal regulations. Work often requires specialised well integrity certifications and detailed fluid volume reporting.

ERAS (Expedited Resource Addition Study)

Industry

A utility or pipeline operator's fast-tracked assessment to connect new energy infrastructure to the grid or network. For subcontractors, an approved ERAS often signals upcoming mobilisation opportunities and tight project timelines. Winning work tied to an ERAS typically means compressed schedules and rapid crew deployment.

Transit-Active Construction

Industry

A project phase where construction work is ongoing while equipment or materials are still in transit to the site. Subcontractors must coordinate mobilisation and scope carefully to avoid costly downtime waiting on delayed deliveries. Billing milestones and crew schedules should account for this overlap.

Project Alliance Agreement

Industry

A contract where the owner, main contractor, and subcontractors share project risks and rewards collectively. Payment is tied to overall project outcomes rather than individual scope performance. Subcontractors must track costs carefully, as savings and overruns are distributed across all alliance members.

IET (Industrial & Energy Technology)

Industry

A broad sector covering technical services and equipment used in oil & gas, power, and industrial facilities. Subcontractors in this space typically provide specialised labour, maintenance, and installation work. Contracts often require trades certification and site-specific safety compliance.

Oil-Directed Rig Count

Industry

The number of rigs actively drilling for oil, tracked weekly by services like Baker Hughes. A rising count signals increased demand for field crews, equipment, and well-site services. Subcontractors use it to anticipate work volumes and adjust capacity accordingly.
