The scheduled order in which different trades perform their work on a project site. Subcontractors must complete their scope before the next trade can mobilise. Delays in your phase can push your crew off-site and disrupt your billing cycle.
Trade Sequencing
Related Terms
Nonresidential Construction
IndustryBuilding projects covering commercial, industrial, and institutional structures rather than homes. For subcontractors, this includes work on warehouses, refineries, offices, and infrastructure. These projects often involve larger contracts, stricter compliance requirements, and longer payment cycles.
Straddle Plant
IndustryA midstream processing facility installed along an existing pipeline to extract natural gas liquids like propane and butane. Subcontractors are frequently mobilised for construction, maintenance, and turnaround work at these sites. Work scopes often include compression, refrigeration, and fractionation system servicing.
Legacy Well
IndustryAn older well built to outdated standards that may require specialised remediation, abandonment, or workover services. Subcontractors should expect non-standard equipment configurations and additional compliance requirements. Scope creep and unforeseen costs are common on legacy well projects.
In-Service Date
IndustryThe date when equipment or a facility is officially commissioned and begins active operation. For subcontractors, this date often triggers billing milestones, warranty periods, or contract close-out requirements. Missing this date can result in penalties or delayed final payment.
Nearshore Abandonment
IndustryThe decommissioning of wells, pipelines, or infrastructure located in shallow coastal waters. Subcontractors typically handle diving operations, cutting, capping, and seabed remediation work. Regulatory requirements are strict, so current certifications and environmental compliance documentation are essential before mobilising.
Laydown Area
IndustryA designated yard space on a jobsite used to store, stage, and organise equipment, pipe, or materials. Subcontractors are often assigned a specific laydown area to manage their tools and gear. Access and cleanliness standards are typically enforced by the prime contractor or owner.
