At MPGQS, we provide defective works expert witness reports that support legal teams, insurers, and property professionals with reliable and technically sound assessments of construction failures. Whether you're asserting or defending a claim related to workmanship, materials, design, or non-compliance, our reporting meets the highest standards required for litigation.
Our qualified building surveyors and engineers—including MRICS-accredited professionals—deliver impartial, thorough analysis to establish causes of failure and liabilities. Every report is written in accordance with the Civil Procedure Rules (CPR Part 35), ensuring full admissibility in court or tribunal.
Our reports are tailored to the complexity and nature of each case. Typical issues assessed in defective works expert witness reports include: poor workmanship or substandard materials; breach of contract and failure to meet specifications; structural defects in residential or commercial buildings; faulty design or engineering errors; water ingress, damp, and fire protection failures; non-compliance with building regulations or planning conditions; misuse or misinterpretation of technical standards; and scope of rectification or remedial works.
Our findings can be delivered in the form of a single Part 35 compliant report or as part of an ongoing expert appointment for multi-party disputes or arbitration.
Our experts are frequently appointed by solicitors acting for claimants or defendants, insurers and loss adjusters, local authorities and housing associations, and developers, contractors, and property owners. Whether engaged under a Scott Schedule format or required to attend court as a Single Joint Expert (SJE), we present facts with clarity and neutrality, strengthening your legal strategy and positioning your case with confidence.
We also assist in disputes involving Section 18(1) diminution in value arguments (where applicable), factual construction timelines, cause and effect sequencing, and interface analysis with other expert disciplines (e.g. M&E, delay, or cost experts).
MPGQS supports clients across major jurisdictions with regional awareness and international standards of service, including the United Kingdom, Ireland, France, Germany, Portugal, Turkey, United Arab Emirates, Saudi Arabia, and Qatar.
Our team brings MRICS-accredited building surveyors, fully CPR Part 35-compliant expert witness reports, decades of construction defect investigation experience, court-tested litigation-friendly documentation, prompt turnaround with ongoing case support, and deep understanding of JCT, NEC, and FIDIC contract frameworks.
