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 and regularly advises clients on digital transformation within an increasingly software and information-driven world.

BIM – Well known but often misunderstood

Most people working within the construction and facilities management industries are familiar with BIM but there’s still some uncertainty around its implementation and its benefits. Studies show that just over 13% of the wider industry has fully embraced BIM Level2 standards, benefitting from the efficiency it provides – which case studies suggest is at least 10% reduction in Design and Build costs (Avanti) but which are predicted to rise with greater usage. This means there is still a long way to go until universal adoption, which is why we want to share our journey with others and collaborate on our digital transformation.

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 is critical currency to all professionals and the end client user-manager. This is why knowledge of the wider industry information process and our clients’ pain points and requirements is our first and foremost critical task and role.

The benefits

Technics is involved from the very early stages of the development process and with our specialist range of services 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 life cycle. 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 and cost, design, satisfaction and productivity efficiencies and cost savings of between 40-85% on capital expenditure (CASurvey4BIMPEX) projects when BIM process is used. An example of this best practice in action is outlined in the UK case study of the Ministry of Justice (MoJ), 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.

Specification

To ensure we understand the deliverables for clients, Technics has created a Survey4BIM guidance document to set out the specification of works and elements schedule that the client requires.

This document highlights the achievable accuracy, our methodology, the level of detail and final outputs. You can also download and digest the full BIM Level 2 standards now hosted by the British Standards Institution (BSI) at www.bim-level2.org, along with the formal definition and other elements required to deliver BIM Level 2.

This is the standard that the industry is aiming towards, the collaborative working and sharing of digital information across project professional groups. The graphic below shows the PAS 1192-2 interpretation of the progressive stages of work. It illustrates the ongoing enhancement of the asset model as it becomes more and more developed with each stage.

Surveyors have a valuable role to play in each of the stages in terms of consultation and data provision. For more information on this process please follow the link to the Survey4BIM group’s publication: “Survey and Digital Plan of Works”.

Our 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 clients receive a rigorous ‘BIM ready’ model in the agreed format to the agreed tolerances. The data capture aspects can be achieved using both Laser scanning and UAV’s 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, co-ordination 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 and HS2, Network Rail London Bridge, residential and commercial projects in London, retail refurbishment programs and providing consultancy for Universities and Schools as they start their transition into BIM.

Technics’ contribution to Survey4BIM

Our role in data provision means we need to sit at the forefront of BIM and information development and to do this weUK BIM Alliance invest our time in key Industry BIM groups. Our Director, Martin Penney is now Chair for the Survey4BIM committee and a member of the Transition Team for UK BIM Alliance, which recently took over from the BIM Task Group the stewardship of embedding BIM Level 2 as business as usual across the wider industry by 2020. Martin’s role supports Technics in providing clients with the right advice and guidance and in developing our role further to manage the client’s assets better.

Technics also offer a consultancy package where we can support you in managing your BIM process to understand each element better.

If you would like to discuss our consultancy package or support with your BIM project, then please call one of our offices or email enquiries@technicsgroup.com
