Define
Decision
Is the opportunity technically and commercially viable?
Minimum evidence
Project charter · site criteria · constraints · risk register · execution premise
Six decision gates
The lifecycle is managed as a sequence of owner decisions.
De-risk
Decision
Is the scope mature enough for investment approval?
Minimum evidence
Feasibility · pre-FEED · basis of design · Class 4/3 estimate · Level 2/3 schedule
Engineer
Decision
Can procurement and construction execute without unresolved interfaces?
Minimum evidence
FEED · specifications · calculations · drawings · quantities · constructability reviews
Source
Decision
Do equipment and contracts meet technical, commercial and schedule requirements?
Minimum evidence
RFQs · bid tabs · purchase orders · vendor data · inspection · expediting · logistics
Build
Decision
Is field progress safe, compliant and tied to the approved baseline?
Minimum evidence
Work packages · field engineering · QA/QC · HSE · cost/schedule control · completions
Start
Decision
Is each system ready for safe energization, startup and performance testing?
Minimum evidence
Turnover dossiers · pre-commissioning · SAT · startup · performance verification · training
Integrated controls
One baseline. One source of status. Named accountability.
Controls are designed before execution starts and scaled to the size, contract model and risk of the mandate.
Governance
Decision rights, approval matrix, stage gates, delegated authority and reporting calendar.
Scope & interfaces
WBS, battery limits, scope register, interface register, deliverable ownership and change traceability.
Cost & schedule
Control budget, coding structure, integrated master schedule, progress rules, forecast and variance analysis.
Risk & change
Quantified exposure, named owners, mitigation dates, trend management and approved change control.
Quality & HSE
Inspection and test plans, surveillance, NCR closure, safe work systems and leading indicators.
Information
Document control, model coordination, vendor data, submittals, RFIs, turnover records and as-built status.
Contracting strategy
Delivery model follows risk allocation.
The contract structure should match scope maturity, market capacity, owner capability, financing requirements and the interfaces the owner is prepared to retain.
Owner’s engineer
Independent technical, commercial and delivery oversight from project definition through acceptance.
EPCM
Integrated engineering, procurement and construction management with transparent owner control of packages and contracts.
EPC / turnkey
Single-point delivery responsibility for defined facilities, systems or work packages with agreed performance obligations.
PMC & program controls
Governance, schedule, cost, risk, change, quality, information and interface control across multiple contractors.
