THDG Consulting Engineers

THDG Consulting Engineers, a structural engineering practice in Chessington

THDG Consulting Engineers is a structural engineering consultancy based in Chessington, near Kingston, Surrey. The practice describes decades of experience and presents itself as a specialist structural engineering company. Its stated area of work covers projects in Surrey, the South East of England and London, without being restricted to those areas.

The firm's own presentation stresses that most of its commissions arrive through recommendations or repeat business, a point it uses to describe its relationship with clients rather than as an independently verified figure.

Design and detailing across the common structural materials

The consultancy's core offer is structural design and detailing, carried out in concrete, masonry, steel and timber. Alongside this, it produces structural reports and checks Part A of the Building Regulations on behalf of local authorities and approved inspectors.

According to the practice, its engineers work to understand the requirements of everyone involved in the building process so that designs offer a safe and economic solution. The firm states that all of its structural engineers have experience applying the relevant British standards and Eurocodes, that it operates as a fully electronic office and that it uses AutoCAD to produce details.

Clients, building types and sectors

THDG has completed projects for architects, private clients, developers and contractors. The range of building types runs from small extensions to developments valued in the millions of pounds, and includes the restoration of sensitive structures. By sector, the practice lists residential, commercial, educational and retail work, and its site navigation also separates residential, commercial, community and recreation, and restoration projects.

The enquiry form on the site distinguishes project types such as new build, extension or loft conversion, commercial, school and survey or report, which reflects the categories of work the practice handles.

Senior partner and professional capacity

The senior partner is Bill Read C.Eng., F.I.Struct.E, described as a practising engineer for over fifty years and as having worked in Guildford and the surrounding areas for approximately thirty years. The practice states that it holds full professional indemnity insurance on an each and every claim basis and has the resources to carry out projects up to £10,000,000 in construction value. It also states that it is Quality Assured to BS EN ISO 9001:2015.

The practice's stated pledge to clients

The firm sets out a client pledge: that a commission will be handled with care and sincerity, that a partner or associated partner will work with the client throughout the project, that the client will be consulted personally at every design stage, that the client will be invited to review and comment on the practice's performance at each stage, and that its commitment will remain total for the duration of the project.
