Project Recovery

We act as an objective, highly experienced second opinion for critical moments.

Independent Commercial Audit & Forensic Review

In high-value property development, uncertainty is the precursor to capital loss. When complex £10m–£100m+ schemes encounter critical milestones, transitions, or structural anomalies, boards cannot rely on self-reported contractor metrics or optimistic projections. At Costra, our Assurance services deliver independent, forensic commercial reviews that uncover the unvarnished truth of your project’s financial and operational health.

We act as an objective, highly experienced second opinion for critical moments. Whether you are prepping for a major funding gate, navigating an impending legal dispute, or investigating suspected cost slippage, our senior principals dig deep into the project architecture. We read the contracts end-to-end and interrogate live metrics to provide the definitive clarity required to protect institutional capital across London and the South East.

The Assurance Protocol

Forensic Commercial Dissection

We bypass high-level dashboards to conduct an exhaustive diagnostic of all project accounts. Our principals forensically analyze real-time cost-to-complete forecasts, contingency allocations, historical variation logs, and supply-chain liability exposure.

Structural & Contractual Interrogation

We cross-reference physical site progress against contractual obligations. We strip away reporting bias to evaluate the true validity of contractor extension-of-time (EOT) claims, design-change variations, and procurement milestones.

Strategic Health-Check & Action Roadmap

We deliver a definitive, lender-grade Assurance Report directly to your board or fund managers. Rather than just listing problems, we provide a pragmatic, highly structured commercial action plan designed to mitigate exposure, correct deviances, and legally fortify your position.

The Assurance Advantage

Unbiased Commercial Truth: An entirely independent, expert third-party appraisal unlinked to project politics or internal delivery biases.

De-Risked Investment Gates: Provides institutional funds and joint-venture partners with the definitive data verification needed to confidently clear funding drawdowns.

Early Dispute Neutralization: Exposing overstatements, contractual ambiguities, and scope gaps early allows you to settle friction before it escalates to formal litigation.

Recovered Capital Leakage: Identifies unapproved variations, clawback opportunities, and hidden supply-chain cushions to protect your bottom line.

Proven Assurance Outcomes

Forensic Assurance Insights

When is the most critical time to commission an Independent Commercial Audit?

While we are frequently brought in during active distress, the most high-value timeline is preemptive. Commissioning an assurance review prior to key project gates—such as transitioning from demolition to main build, executing major tier-one contract awards, or closing out key funding phases—prevents systemic risks from escalating.

How does an Assurance Health Check impact our relationship with the Main Contractor?

Our process is calm, professional, and entirely evidence-based. We do not operate with an adversarial mindset; we operate with a forensic one. Because we rely strictly on contractual realities and validated metrics, our audits often desensitize tense project environments by replacing emotional arguments with objective fact.

What makes Costra’s forensic reviews different from standard auditing firms?

Traditional auditors check numbers against checkboxes from a desk. Costra’s principals have stood on active, complex sites, read the contracts line-by-line, and felt the weight of real-world deadlines. We pair financial auditing with deep field experience, meaning our reports don’t just flag mathematical errors—they solve structural project delivery problems.
