How We Deliver

The Project Delivery Assurance Framework (PDAF)

A structured, auditable and repeatable delivery framework providing consistent governance, assurance and control throughout the project lifecycle.

Why PDAF?

Survey and site investigation programmes are among the most technically complex workstreams within Offshore Wind and Oil & Gas developments. They involve multiple stakeholders, specialist contractors, regulatory interfaces, commercial pressures and significant health and safety responsibilities.While most organisations have established project management processes, many programmes still experience inconsistent governance, unclear ownership, reactive decision-making and fragmented delivery.PDAF was developed to address these challenges.Rather than treating projects as a collection of disconnected activities, PDAF provides a structured methodology that defines every stage of delivery, every decision point and every accountable function from project initiation through to close-out.The result is a delivery framework that is:✔ Structured✔ Auditable✔ Repeatable✔ Practical✔ Built for real-world delivery

What is PDAF?

The Project Delivery Assurance Framework (PDAF) is a stage-gated project delivery methodology specifically developed for offshore and land-based survey and site investigation programmes.Built upon the principles of IOGP Report 423 and aligned with CDM 2015, the framework integrates governance, assurance, procurement, technical scope development, HSE, commercial management and project controls into a single, cohesive delivery process.Unlike traditional project management methodologies, PDAF has been specifically designed around the unique operational requirements of survey and site investigation projects.Every task has an accountable owner.Every stage has defined deliverables.Every gate represents a clear governance decision.Every transition is controlled.

One Continuous Delivery Lifecycle

Six stages. Six gates. One proven methodology.

PDAF structures every project through a continuous six-stage delivery lifecycle.Rather than progressing directly from planning into execution, projects move through clearly defined stages, each concluding with a formal decision gate that confirms readiness before progressing.This stage-gated approach ensures that scope, procurement, contractor readiness, commercial commitments and HSE obligations are confirmed before work advances to the next phase.The six stages are grouped into three delivery phases:Determine: Identify and Prepare the project.Define: Tender, appoint and validate.Deliver: Execute, oversee and close.

Risk & Influence Across the Project Lifecycle

The PDAF Risk & Influence Profile illustrates how client influence, contractor influence and project risk evolve throughout the delivery lifecycle. By front-loading governance, assurance and critical decision-making into the early stages of a project, PDAF ensures key risks are identified and managed before field activities commence.The framework also establishes a single, clearly defined point of responsibility transfer between the client and contractor, providing greater clarity, stronger governance and improved control throughout project execution.

The Six Stages

Every PDAF stage has a defined purpose, accountable owner and expected deliverables.The framework provides a consistent governance model from the earliest stages of project planning through to final close-out and lessons learned.

Eight Functions. One Accountable Framework.

One of PDAF’s defining characteristics is clear ownership.Every activity is assigned to one of eight accountable functional areas, ensuring that governance responsibilities are transparent throughout the project lifecycle.This removes ambiguity, improves collaboration and provides a clear audit trail for every decision.

Influence Early. Transfer Risk with Confidence.

Successful project delivery depends upon making the right decisions at the right time.The PDAF Risk & Influence Profile demonstrates how the client’s ability to influence project outcomes is greatest during the early planning stages, while contractor responsibility and operational risk increase as field activities commence.By concentrating governance, assurance and key decisions during the planning phases, PDAF ensures that projects enter execution from an assured baseline.A single, clearly defined contractor risk-transfer point provides an auditable transition of responsibility and establishes a clear interface between client and contractor obligations.

Operational by Design

PDAF is more than a governance framework.It is designed to be used every day.The framework is operationalised through Microsoft Planner and SharePoint, providing a live project management environment that supports governance, progress tracking and document control throughout delivery.Planner manages the work.SharePoint stores the evidence.Together they provide a structured, auditable and repeatable operating environment aligned with PDAF.

Why Organisations Adopt PDAF

PDAF provides practical benefits throughout the project lifecycle.
