BIM Surveys

Our role as surveyors across the built environment and on infrastructure projects continues to expand as we take increasing responsibility to support clients in their data and asset management requirements.

As a proactive and collaborative member of the geospatial industry, Technics recognises the benefits of BIM (Building Information Modelling), both to the UK and internationally. We regularly advise clients on digital transformation within an increasingly software and information-driven world.

What is building information modelling?

Most people working within the construction and facilities management industries are familiar with BIM, but there’s still some uncertainty around its implementation and benefits.

BIM could also be defined as “Better Information Management”. It is a collaborative way of working that provides the user with a transparent process, using digital technology to design, construct and maintain the entire lifecycle of their asset.

Throughout this lifecycle, geospatial consultancy and valid digital data, geometry and information are critical currency to all professionals and the end client user-manager. This is why understanding the wider industry information process, as well as our clients’ pain points and requirements, is our first and foremost critical task and role.

Why use building information modelling?


Technics is involved from the very early stages of the development process. With our specialist range of services, we can provide support in understanding the value of using valid and accurate data, geometry and information in a format that you can use throughout the asset lifecycle.

Collaboration in each phase of construction is paramount. The Avanti process and study, the forerunner to the current BIM Standards, has already shown valid price, cost, design, satisfaction and productivity efficiencies with cost savings of 40-85% on capital expenditure projects when the BIM process is used. An example of this best practice in action is outlined in the UK case study of the Ministry of Justice, an early adopter of BIM which realised 20% savings on a £20m project.

We believe this value proposition will improve over time as the industry embraces the digital changes and a more fully collaborative and digital way of working. By using the right information and type of data at the right time, clients can begin to realise the benefits of a digital built environment.

Setting out a specification for BIM

To ensure we understand the client’s data requirements, Technics consults on an individual basis to create a bespoke specification of works and an elements schedule.  Our specification highlights the achievable accuracy, our methodology, the level of detail and final data output and format.  This ensures that clients will receive the appropriate data at the appropriate project stage.

You can see and download the full suite of BIM Level 2 standards, as hosted by the British Standards Institution (BSI), which provides the necessary guidance for clients and practitioners alike and other useful information.

These form the standards that the industry is aiming towards; using collaborative working and the sharing of digital information across project professional groups and clients.

Surveyors have a valuable role to play in each of the stages in terms of consultation and data provision.

Technics’ experience in Survey4BIM

Technics has been providing 3D data for decades. Now, with advanced specifications for asset and data management and BIM, we’ve adapted our process to ensure that our clients receive a rigorous ‘BIM-ready’ model in the agreed format, and to the agreed tolerances. The data capture aspects can be achieved using both laser scanning and UAVs to create a point cloud data of the asset.

For major infrastructure projects, we also use the Mobile GPR system for mass data capture to provide the underground environment intelligence. Agreeing the specification at the start of each project is paramount. Understanding the output, coordination and level of detail required are crucial to our methodology in both the field and office.

Our experience includes working on major infrastructure projects for transportation, such as:

  • Heathrow Airport
  • HS2
  • The redevelopment of London Bridge Station on behalf of Network Rail
  • Residential and commercial projects in London
  • Retail refurbishment programmes
  • Providing consultancy for universities and schools as they start their transition into BIM
