A project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.
Progressive Design-Build
Related Terms
Winter Road
IndustryA temporary road built over frozen ground, muskeg, or ice to access remote sites during winter months. Subcontractors must plan mobilisation, equipment moves, and material hauls around strict seasonal opening and closing dates. Missing the window can delay a project by a full year.
Gas Sales Precedent Agreement
IndustryA conditional agreement between a producer and gas buyer that must be satisfied before a project moves to full development. For subcontractors, it signals that major field mobilisation and long-term work commitments depend on this deal closing. Delays or failed negotiations can stall contracts, procurement, and crew deployment.
Limited Notice To Proceed
IndustryAn LNTP (Limited Notice to Proceed) authorises subcontractors to begin a defined scope of work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities up to a specified dollar limit. Work performed beyond that limit is at the subcontractor's own risk until full NTP is issued.
Pipeline Open Season
IndustryA formal period when a pipeline operator solicits capacity commitments from shippers before building or expanding a line. For subcontractors, it signals upcoming construction and maintenance work. Winning bids during this phase often trigger mobilisation timelines and crew planning.
CIP (Capital Improvement Program)
IndustryA planned cycle of major infrastructure upgrades or expansions at a facility, often releasing large volumes of subcontract work. For field service companies, CIPs signal sustained project pipelines worth pursuing long-term agreements for. Monitoring client CIP schedules helps subcontractors forecast workload and mobilise crews strategically.
Clear-To-Build
IndustryA formal go-ahead issued by a prime contractor or owner confirming all approvals, permits, and engineering are in place. Subcontractors should not mobilise crews or materials until this authorisation is received. Starting work without it can void contract protections and leave you liable for costs.
