Heavy precast concrete blocks or collars used to anchor pipelines and prevent buoyancy in wet or unstable ground. Subcontractors install them during pipeline construction, often requiring specialised lifting equipment and crews. Scope and quantity directly affect labour hours and equipment costs in your bid.
Concrete Ties

Gas Rigs
IndustryDrilling rigs specifically configured to drill natural gas wells, requiring crews and equipment rated for high-pressure gas formations. For subcontractors, gas rigs often demand specialised certifications and H2S training. Work volumes typically follow natural gas commodity prices and seasonal heating demand.
Grid-Tie
IndustryA system that connects on-site power generation to the utility grid. Subcontractors working on grid-tie installations must coordinate with utility companies and meet strict interconnection standards. Common on solar and wind projects in remote industrial or construction settings.
Shaker Screens
IndustryMesh filters mounted on shale shakers that separate drill cuttings from drilling fluid on the rig. Subcontractors handling fluid management or solids control must track screen condition and swap them regularly. Damaged or plugged screens slow operations and can trigger downtime charges against your crew.
Epc (engineering, Procurement, and Construction) Contractor
IndustryA company hired to deliver a project from design through build, acting as the main contractor above subcontractors. As a subcontractor, your client and contract holder is typically the EPC, not the asset owner. They control scope, scheduling, and invoice approval on site.
Ip Rate (initial Production Rate)
IndustryThe IP Rate measures a well's output immediately after it comes online, typically in barrels or mcf per day. Operators use it to assess well performance, which directly affects how quickly field service contracts ramp up or wind down. A strong IP Rate often signals sustained work volume for subcontractors on site.
TOFD (Time-of-flight Diffraction)
IndustryAn ultrasonic weld inspection method used to detect and size internal flaws in pipelines and pressure vessels. Subcontractors performing NDT work must hold TOFD-specific certifications to qualify for this scope. It is widely accepted by regulators as an alternative to radiographic testing.
