Temperature-controlled storage units used on job sites to preserve perishables, vaccines, or heat-sensitive materials. Subcontractors may need to supply or rent these units for remote or long-duration projects. Costs are typically itemised as a reimbursable expense in the contract.
Refrigerated Storage
Related Terms
Conduit Installation
IndustryThe process of routing and securing protective tubing or piping to house electrical wiring on job sites. Subcontractors are typically scoped for this work during facility builds, plant turnarounds, or infrastructure upgrades. Accurate material take-offs and labour estimates are critical to pricing this work profitably.
ISNetworld
IndustryA contractor management platform used by operators to verify that subcontractors meet safety, insurance, and compliance requirements before being allowed to work on sites. Maintaining ISNetworld compliance is essential for subcontractors working with major operators.
Hub
IndustryA central staging location where crews, equipment, and materials are coordinated before deployment to remote job sites. For subcontractors, the hub determines mobilisation routes, laydown areas, and logistical costs. It often serves as the main point of contact between the prime contractor and field crews.
Cavern Storage
IndustryUnderground 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.
Negative Gas Prices
IndustryOccurs when oversupply forces producers to pay buyers to take gas, signalling severe market stress. For subcontractors, this often triggers rapid project suspensions, deferred work orders, and delayed payments. Expect scope reductions and early contract terminations when prices turn negative.
SAGD (Steam Assisted Gravity Drainage)
IndustryA heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.
