TFT structural engineering services help building owners identify and address building defects, protect building users, and give older assets a new lease of life. We combine technical expertise with commercial insight to manage risk, enhance performance and support better investment decisions across the lifecycle of built assets.
Structural engineering ensures that buildings are safe, stable and fit for purpose across their lifecycle. Starting with understanding a building’s function, setting and the stresses and strains it will experience, structural engineers meticulously select materials, balancing structural performance with durability and embodied carbon considerations and assess issues with the structural components of a building.
TFT specialises in the assessment, investigation and enhancement of existing structures, with particular expertise in assessing building defects, working on heritage assets and managing complex urban developments.
Our services span building pathology, structural assessments, technical due diligence, expert witness advice, fire and blast mitigation and development monitoring.
Building pathology is the systematic investigation of defects, their causes, consequences and remedies, including factors such as material degradation, design issues, loading conditions and ground or soil movement. This is a core skillset for our structural engineers, and enables us not only to repair or restore buildings, but to future-proof them by addressing the root causes of their weaknesses.
By combining knowledge of construction materials, structural behaviour and environmental factors with practical problem-solving and clear communication, TFT helps clients maintain safety, durability and compliance while protecting long-term asset value.
Structural challenges can expose assets to safety risks, regulatory non-compliance and unexpected costs. Professional structural engineering support helps address these issues by providing clarity, certainty and actionable solutions:
Our structural engineering expertise
TFT’s structural engineers are specialists in existing buildings. This includes understanding the interaction between structure, façade and ground conditions, particularly in dense urban environments with deep basements, complex soil profiles and nearby tunnelling or infrastructure works.
We combine forensic insight with commercial awareness to deliver practical, risk-managed solutions that support investors, developers and owners. Our experience spans complex defect diagnosis, historic buildings, RAAC and major incident response.
We take a holistic approach, integrating structural engineering with façade engineering, building surveying, cost consultancy and project management. This multidisciplinary capability enables us to manage complex challenges and deliver joined-up advice across the entire asset lifecycle.
Our focus is always on identifying root causes, managing risk and future-proofing assets, helping clients make confident decisions around compliance, liability, maintenance and long-term value.
We focus on existing buildings and complex defects, using building pathology to diagnose root causes rather than symptoms. Combined with commercial awareness, this ensures solutions are practical, proportionate and aligned with asset value.
Structural engineering focuses on the integrity and safety of load-bearing elements, while building surveying takes a broader view of condition, compliance and maintenance across all building components.
Structural engineering work in the UK is governed by Building Regulations, British Standards and relevant safety and fire legislation. Compliance requirements vary depending on asset type, use and level of risk.

Bill has over 40 years’ experience in structural engineering including commercial, retail, residential, educational and hospitals and during that time has gained recognition as a leading specialist in the repair / refurbishment of historic / listed buildings including Regent Street Disease, RSD, and conservation management reporting, damage mitigation from tunnelling beneath city centre buildings, (Jubilee Line and Cross Rail), and in disaster management where over the past 30 years he has been involved with the consequences of many of the major disaster and terrorist incidents in the UK providing post event building recovery and renewal expertise to property owners, developers, designers and managers including the 2005 Buncefield Oil Depot explosion.
Bill sat on the RICS President’s Commission for Major Disaster Management, leading the research and development of protocols for government agencies, NGO’s, contractors, architects and consultants and independently writing many papers.


Alfred is part of our structural engineering team, with experience in forensic structural engineering, examining material deterioration mechanisms for durability assessments, Regent Street Disease assessment & treatment options and durability design & specifications. He also reviews durability requirements of engineering drawings & details for structures along the route for Concept to For Construction design packages, Durability Management Plans (DMP) for major road, rail & water infrastructure and determination of Operations & Maintenance programs.
He is widely involved in conducting various levels of asset condition investigation &assessments including diagnostic testing for reinforced concrete, steel, stone, terracotta, faience & timber assets, & recommending suitable &cost-effective rehabilitation repair options.
