The planned order in which tasks or scopes are completed on a job site. Subcontractors rely on sequencing to schedule crews, avoid downtime, and coordinate with other trades. Delays in sequencing often trigger cascading cost and scheduling impacts.
Work Sequencing
Related Terms
Mid-Continent
IndustryA regional designation covering oil and gas producing areas across Oklahoma, Kansas, and parts of surrounding states. For subcontractors, it signals a distinct labour market, regulatory environment, and client base. Mobilisation costs and crew logistics differ significantly from other North American basins.
ROV (Remotely Operated Vehicle)
IndustryAn unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.
LOI (Letter of Intent)
IndustryA written commitment from a client indicating they plan to award a subcontractor a contract. It allows work or mobilisation to begin before the formal contract is signed. LOIs are not always legally binding, so subcontractors should clarify payment obligations before proceeding.
Hydrovac
IndustryA truck-mounted unit that uses pressurised water and a vacuum system to excavate soil safely around buried utilities. Subcontractors are frequently hired for hydrovac work on pipeline, civil, and utility projects. It is preferred over mechanical digging in areas with high strike risk.
Wireline
IndustryA method of lowering tools, instruments, or equipment into a wellbore via a steel cable, commonly used for well logging, perforating, and intervention services. For subcontractors, wireline work is typically scoped as a specialised service requiring certified operators and dedicated equipment spreads.
Project Delivery Method
IndustryThe contractual framework that determines how an owner, general contractor, and subcontractors are organised on a project. It directly affects when you get hired, who you report to, and how your scope is defined. Common methods include DBB (Design-Bid-Build), DB (Design-Build), and EPCM (Engineering, Procurement, and Construction Management).
