Industry Glossary Term

Grid Hardening

Upgrades to electrical infrastructure that improve resilience against outages, extreme weather, and physical damage. For subcontractors, it drives demand for line work, equipment installation, and civil construction crews. Contracts often involve tight timelines and utility compliance requirements.

Related Terms

Saas (software As a Service)

Industry

Cloud-based software you access via subscription instead of buying and installing it outright. For subcontractors, this covers tools like invoicing, scheduling, and compliance tracking platforms. You pay a recurring fee and can access the software from any jobsite device.

Exploration Well

Industry

A well drilled in an unproven or lightly tested area to determine whether hydrocarbons are present, often representing shorter-term, high-mobilisation contracts for subcontractors with less predictable follow-on work than development drilling programmes.

Long-Lead Items

Industry

Equipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.

Working Interest

Industry

An ownership stake in an oil and gas lease that obligates the holder to pay a share of exploration and production costs. For subcontractors, knowing who holds working interest helps identify who is ultimately responsible for approving work orders and invoices. Operators typically hold majority working interest and are your primary point of contract.

Cold-Milling

Industry

A pavement removal process where a rotating drum grinds away asphalt or concrete surfaces without heat. Subcontractors use it for road rehabilitation, site prep, and surface levelling on construction and industrial projects. Milled material is typically recycled or hauled off-site by the crew.

PAUT (Phased Array Ultrasonic Testing)

Industry

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds, pipelines, and structural components for defects. It produces detailed cross-sectional images without cutting or damaging the material. Subcontractors offering PAUT services typically require certified Level II or III technicians and specialised portable equipment.
