What Went Wrong? Failed Landscape Projects Explained

What Went Wrong? The Anatomy of Failed Landscape Projects

Expert witness dispute reviews examining how landscape projects fail, why failures occur, and how they are assessed.
 
The What Went Wrong? series examines real landscaping disputes through the lens of expert witness review methodology. Each article looks at a specific type of project failure, using anonymised case material to explain how defects are investigated, recorded and assessed against written specifications, site conditions, workmanship, British Standards where applicable, and recognised Industry Best Practice.

Understanding Landscape Project Failures

Failed landscape projects are rarely caused by one isolated issue. In many cases, the visible defect is only the final symptom of deeper problems involving design, specification, material selection, workmanship, drainage, levels, sequencing or contract interpretation.

This series has been created to help contractors, designers, specifiers and paving professionals understand how failures are reviewed when a dispute reaches the stage of formal expert witness assessment.

The articles do not provide legal advice or remediation proposals. Instead, they focus on the evidence-led process used during expert witness inspections and court-compliant reporting. The aim is to show what went wrong, why it matters, and how those failures are identified during a professional dispute review.

How the Failures Are Assessed

Each article in this series is based on the type of methodology used during expert witness dispute reviews. This may include desktop assessment, written briefs, site inspections, photographic evidence, contractor specifications, contract documents, invasive investigation, industry guidance, British Standards where relevant, and the competing positions of the claimant and defendant.

Expert witness reports are prepared for the court system and must remain independent, impartial and evidence-based. The role of the expert is not to act as an advocate for either party, but to explain the technical issues clearly and support opinions with observed facts, professional experience and recognised standards.

Where appropriate, the articles refer to issues such as poor bonding, incorrect levels, inadequate drainage, material substitution, defective bases, retained soil, air brick obstruction, damp proof course violations, poor detailing and unsafe construction.
