Why eBIM?

Existing Building Information Modelling

Why eBIM? Because Building Information Modelling is the biggest change in the construction sector, since CAD replaced hand drafting.

What is eBIM?

Building Information Modelling is the biggest change in the construction sector, since CAD replaced hand drafting. Existing Building Information Modelling (eBIM) is the first step in the BIM workflow for retrofit & refurb projects.

BIM was developed as a way of managing the full development lifecycle of a building project. Used to facilitate new designs, build changes and communication amongst contractors and design teams, it has provided significant cost savings and efficiency gains. As these methods have become more robust, companies have looked to apply these techniques to a range of projects. Combined with the current downturn in the new build sector, many firms have seen the majority of their construction work switch to retrofit and refurb projects instead of new build.

Architects and contractors want to now apply these skills to refurb projects, however the assumption has been that trying to model existing buildings and structures in Revit is time consuming and extremely costly.

To fill this gap Digital Surveys an established 3D laser scanning and survey company have launched eBIM, Existing Building Information Modelling. By using the latest 3D laser scanning data capture techniques they can survey in 3D and convert this information to accurate Revit models.

Who is it For?

Architects, Contractors & Engineers

eBIM provide asbuilt BIM models to architects, engineers and contractors who are working on retrofit or refurb projects and what to do this in a BIM environment. For many architects up till now the only way to create as built BIM models was to pull together existing or design plans and manually build up a model. These plans would often be hardcopies and bare little representation of the asbuilt state of the property. The assumption up until now was that to accurate model existing sites would be too time consuming and not cost effective.
Using the latest 3D laser scanning data capture techniques eBIM™ can now quickly and efficiently survey existing buildings in 3D and hand over full as built 3D BIM models to the client.
This allows the whole design team to hit the ground running with an accurate model already in Revit.

Facility Managers, Owner Operators, Estate Managers

With the government now firmly committed to BIM on all projects by 2016, the wider market place is beginning to look at implementing BIM solutions. Design and construction are only a fraction of the building’s lifecycle and cost. Owner operators and FM managers are now seeing the benefits gained from converting their estates to FM BIM.

Why Use eBIM?

eBIM replaces the need for traditional 2D surveys and delivers accurate as built models of existing buildings and infrastructure as parametric Revit models. This is achieved faster, with a greater accuracy than traditional methods reducing overall project costs.

In the past a measured building survey would be carried out by a surveyor, armed with a total station and a disto. Using the total station, reflectorless shots would be taken to key points on the facade of the building. Internal measurements would be taken with a disto and either fed into a palm top computer or recorded manually. Back in the office this data would be opened in AutoCAD and the surveyor or CAD technician could then draw up his plans and elevations in 2D. For the last 20 years this method has worked very effectively.

However Building Information Modelling is fundamentally changing this process. BIM requires a much higher level of detail in the survey and most importantly it requires this in 3D.

It is possible to build a 3D BIM model from 2D CAD deliverables, however to do this is time consuming, prone to errors and lacking in sectional detail. It is also hard to visualise 2D plans in 3D.

The solution to this is 3D LASER SCANNING. 3D laser scanning has been around in the offshore sector for over 10 years. The offshore sector uses laser scanning to scan and create accurate As-Built models of oil rigs and plant facilities. However it is only in the last couple of years that the technology has been cost effective to use in the wider architectural sector.
