Industry Glossary Term

Long-Span Structural Systems

Structural frameworks that cover large distances without intermediate supports, such as trusses, arches, or space frames. Subcontractors encounter these in industrial buildings, processing facilities, and modular plant construction. Work in these areas often requires specialised rigging, elevated access planning, and load-path awareness.

Related Terms

Hydroblasting

Industry

High-pressure water jetting used to clean, strip, or cut surfaces on industrial equipment and structures. Subcontractors typically require specialised certification and equipment to bid this scope. It is common in tank cleaning, pipeline maintenance, and surface prep work.

Cavern Storage

Industry

Underground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.

Spot Work

Industry

Short-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.

CRA (Corrosion Resistant Alloy)

Industry

Specialised metal used in pipelines and equipment exposed to corrosive fluids like H2S or CO2. Subcontractors must confirm material specs before welding or fabricating, as CRA requires certified procedures and qualified welders. Misidentifying CRA components can cause costly failures and compliance issues.

BPD (Barrels Per Day)

Industry

A measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.

Throughput

Industry

The volume of work or units a crew completes within a set timeframe. Higher throughput means more billable output per shift, directly affecting your contract profitability. Subcontractors often track throughput to justify crew sizes and equipment needs.
