The Vertex Companies

The Vertex Companies, known as VERTEX, is a global professional services firm founded in 1995. It combines traditional architecture, engineering and construction (AEC) services with forensic consulting, an integration that has defined the firm since its founding. VERTEX operates across North America and EMEA, serving clients in architecture, engineering, construction, legal services, insurance, real estate development, property ownership and the public sector.

The firm's work spans several technical domains: forensic engineering and investigations, construction and program management, project advisory, environmental services, compliance, building sciences, risk assessment, dispute resolution and expert witness services. In practice this means supporting organisations through complex projects, claims, disputes and regulatory challenges - from investigating technical issues and project risk, to managing construction programmes, to advising on environmental and construction claims.

Expert witness work forms a distinct part of the practice, supporting law firms and dispute resolution proceedings. Other service lines include forensic investigation and engineering, project advisory for complex projects, construction and program management, environmental services, and regulatory and compliance support for organisations navigating technical and regulatory issues.

Work at VERTEX is characterised by multidisciplinary expertise and an integrated approach that brings AEC services together with forensic consulting.
