Services
Specialist advice across contract, time and cost.

Connected specialist expertise
Contractual entitlement, programme impact and quantum belong in the same conversation.
A variation, delayed handover or disputed payment rarely concerns one discipline alone. Constructive Advisory combines senior contractual and commercial judgement with programme and delay analysis to test the evidence, quantify the implications and inform the next decision.

Flexible engagement models
One project, or the wider portfolio.
Project-based work remains appropriate for a defined claim or decision. Where several projects face recurring notices, delay exposure, disputed variations or payment issues, a portfolio engagement is our recommended approach. It enables earlier, more consistent review and can deliver better value than repeatedly commissioning isolated assignments.
Who we support
Advice matched to your role and objective.
Support can be provided for a defined claim, integrated into a live project team, or arranged as an ongoing project or portfolio retainer. Reporting and deliverables are tailored to the people making commercial and technical decisions.
Developers and employers
Independent reviews of contractual exposure, programme certainty, valuations and project or portfolio risk.
Consultants and project teams
Specialist project controls, contract administration, quantity surveying and commercial support alongside delivery teams.
Legal teams and appointed experts
Independent delay and quantum assessments, issue chronologies, evidential reports and dispute support.
Our method
Understand
Define the objective, contractual position, evidence and decision the analysis must support.
Test
Interrogate programmes, records, assumptions and causal links rather than accepting the first narrative.
Explain
Translate technical analysis into a clear, structured and commercially useful account.
Resolve
Focus the work on practical outcomes, proportionate strategy and earlier resolution.
Next step
Start with the issue that needs a decision.
Tell us the project, the commercial or programme issue and any urgent deadlines. We can agree a proportionate initial review and whether a single engagement or portfolio arrangement makes more sense.
