Trade Sequencing

A document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.

A small-diameter initial hole drilled along a planned path before reaming to full size, commonly used in horizontal directional drilling. Subcontractors use it to verify alignment and ground conditions before committing to the full excavation scope.

A structural shell installed inside a bored tunnel to support surrounding soil or rock and maintain bore integrity. Subcontractors installing liners must meet strict tolerances and inspection hold points. Work is often sequenced tightly with boring crews, requiring close schedule coordination.

A backlog of energy projects waiting for approval to connect to the electrical grid. For subcontractors, queue position determines project start dates and can cause significant mobilisation delays. Long wait times directly affect labour scheduling and equipment commitments.

A system of electric cables or steam lines wrapped around pipes to prevent freezing or maintain process temperatures. Subcontractors are often hired to install, inspect, and commission these systems during turnarounds or new construction. Common in cold-climate facilities handling water lines, instrumentation, and process piping.

A contract that limits a subcontractor to one defined service or trade, such as civil work or instrumentation. It prevents scope creep by clearly separating responsibilities between contractors. This structure helps subcontractors price accurately and avoid liability for work outside their expertise.
