Overcoming BIMtimidation: Taking The Plunge With BIM
Belgian Firm MBG integrates BIM for the first time on a large scale hospital build.
While Architecture, Engineering and Construction (AEC) professionals are rarely given proper credit for being innovative, the tech sector of the industry has grown so exponentially over the past decade that many new digital possibilities have emerged, leaving the options for integration a bit overwhelming. This is especially true for small to midsize companies within AEC. The technological boom yields incredible advantages when implemented correctly, but that very implementation process raises so many questions that it can become a daunting predicament. Firms often ask, “What software do we need?” “When should we try to go digital?” “What exactly is BIM and how can we quantify the value of using new technology?” If you’ve asked yourself these and many other related questions, you certainly are not alone.
To further complicate things, given the increase in Public-Private Partnerships (PPP), the impending UK BIM mandate, Brexit ramifications, and possible government standardisations, the very choice of whether or not to use digital solutions is gradually being taken out of the hands of prime contractors on a global scale. Owners and government agencies are instead making the call, indicating that digital solutions are likely here to stay – but just how deep these digital solutions need to go remains to be seen. As the tide of BIM and Virtual Design and Construction keeps rising, getting pushed into the water might just be the best way for firms to learn how to swim.
Come On In, The Water’s Just Fine
One firm can certainly attest that despite the initial waves, the water is just fine. Belgian firm MBG is taking the BIM plunge for the first time on the Belgian Industrial CFE affiliate’s £105 million AZ Sint-Maarten Hospital project in Mechelen – hardly the ideal project on which to experiment.
The public and privately funded nature of the project left the firm little room to negotiate on technology solutions. (This is not a full PPP project, but financially, private partners VZW Emmaus–AZ Sint-Maarten need to follow rules applicable to government instances because they benefit from the project’s subsidies.) “Our client made the decision to design this hospital in BIM,” says Project Manager Bens Bervoets. As the contractor for the project, MBG was more than willing to adapt to the digital challenges head-on. “This is one of the first big projects here in Belgium being done in BIM format, with Revit creating a 3D model.”
With a five-year build plan totaling nearly £303 million for the finished hospital, the wide-open possibilities of how technology would be implemented on such a grandiose project was the first obstacle to tackle. “We don’t have a standard here in Belgium yet for how to work with BIM – they are currently working on a European standard, but they haven’t finalised it,” says Bervoets. “For projects like this, there is a mountain of project information that has to be transferred to the right people at the right time. Modern technology can provide solutions for everyone to make their job more efficient.” In this case, the technology suite included Buzzsaw (project extranet), Aproplan, Revit, Tekla, Navisworks and Bluebeam Revu – all of which were new to MBG.
“I believe this software should be used like Word and Excel. I use Bluebeam every day!” – MBG Project Manager Bens Bervoets
Not Lost In Translation
As a project manager, Bervoets’ key challenges include ensuring the information from the complex BIM programs could be properly translated and sent to the field, as well as gaining project partner approval for all updated drawings. “Normally we would get some drawings from our contractors and subcontractors and we’d have to review them, which would require me to print the drawing and make all my remarks the old school way, on a table with all my drawings as colours,” explains Bervoets. “And then I’d have to go to our offices in Antwerp and scan them in A0 size. This is not a very complicated process, but it takes a lot of time.” Instead, he used Revu to translate the informational drawings and host the markups. “I can make all my markups in the program digitally, send them to the subcontractors and suppliers, and they can easily send me their revisions in a PDF. We primarily use the annotations, hyperlinking and measurement tools. It’s a good program because not every contractor, and definitely not every subcontractor or smaller player on the project, has the BIM software or the right staff to work with it. So, especially with smaller subcontractors, we use Revu.”
If You Can Show It, They’ll Know It
The other component that eased MBG’s transition to BIM was the very device that showed the drawings. “We are using a big touch screen because it can show an A0-size drawing without zooming,” Bervoets declares. “That makes it an easier adjustment for workers who are used to checking drawings on the plotter paper.” Not only did MBG save money and time by not needing to print on plotter paper, but also project latency was practically eliminated between drawing approval and posting on the touch screen. Bervoets elaborates, “We use the screen for meetings with the foremen of subcontractors so that our site superintendents can easily discuss short-term planning, because you can take a floor map of, for example, level 2 of the building, and you can easily mark it up using Revu on the big screen. You can easily make markups with colours, and then we can save it on the project extranet [making it possible to carry the documents along on site using an iPad] or send it to them via email.”
On Track and Moving Ahead
Despite using BIM for the first time, MBG’s AZ Sint-Maarten Hospital project is moving full steam ahead and, more importantly, is right on schedule. Bervoets and his MBG team are happy to have taken on the challenge. “For this project, there were a lot of test cases coming together. We had the screen, and BIM and Bluebeam Revu, and I think these will become standard practices on our future jobs.”
