Technical due diligence examines the background, condition and assumptions of a project or facility. Its purpose is to identify gaps and uncertainties relevant to a decision, within a defined scope and review criteria.
Distinguish evidence, assumptions and outstanding items
A technical review must make clear which information supports a conclusion and which matters require verification. The assessment may focus on design, asset condition, execution readiness or intervention needs.
Findings are organised according to their relevance to the decision. The technical review provides information for the evaluation process and is coordinated with other disciplines where the scope requires it.
Service scope
The scope is defined according to asset condition, project stage and available information.
Review of background information
Documentation is analysed against the agreed objective and criteria. Inconsistencies or gaps are recorded to inform queries and additional checks.
Design basis and technical documents
Scope status and consistency
Gaps and verification queries
Technical capabilities
Review a project using verifiable evidence
Definition and technical feasibility
The review compares the intended scope with studies, site conditions and supply arrangements. Conclusions distinguish verified information, assumptions and matters requiring further analysis.
Study and engineering maturity
Site conditions and infrastructure
Gaps affecting the decision
Condition and operational readiness
For existing assets, the assessment connects performance, integrity and intervention needs. For projects under development, it reviews dependencies and handover readiness based on the available information.
Operating and inspection records
Execution constraints
Recommendations and outstanding checks
Deliverables and coordination
Information for decision-making+
Deliverables are agreed when the service is defined. The bases used, results and outstanding checks are documented so that the information can carry through to the next stage.

Background information to get started+
An initial review confirms what information is available and what needs to be completed. To prepare for that discussion, it is useful to have:
