Pioneering planning and project execution with Open BIM

“The end-to-end use of BIM solutions constitutes genuine added value for all stakeholders in the building process
because it enables seamless and efficient collboration”

Steven Hendrickx, Head Architect in Hasselt

Large-scale, highly complex building projects in particular require ongoing, reliable and efficient coodination between all stakeholders – both internal and external – across disciplines and between companies. Therefore, in association with other market players, the Nemetschek Group is promoting the Open BIM data standard. This is a universal, collaborative approach to designing, constructing and operating buildings based on open standards and workflows It makes it possible for project stakeholders to collaborate, even if the type of software varies from user to user. The Industry Foundation Classes (IFC) interface has established itself as an open standard and is therefore of central significance.

Sharing and evaluating data throughout the entire product life cycle saves time and money and improves quality. The administration of data is key to this digital transformation, for it is only possible to take full advantage of the potential if each stakeholder can access the data that he or she needs at any given time. This begins with a realistic BIM building model, which is an essential prerequisite for a genuine 5D workflo. This model is no longer limited to just 3D construction data; it also includes data concerning the dimensions of time and costs.

Seamless collaboration exemplified by the Hasselt City Hall

Under the management of the architect team comprising Jaspers-Eyers, MASS Architects and Michel Janssen, a new municipal administration center is being built in Hasselt. The complex, consisting of a renovated building section and a new building, provides approx. 17,000 m2 for the city administration and social services as well as offices. The architects and their most important partners are using Open BIM software solutions for the entire construction process. Three Nemetschek solutions are being implemented for this project: Archicad from Graphisoft for the design and planning of the architects, Allplan Engineering for civil engineering, and the Solibri Model Checker for the BIM quality control carried out by the construction company.

From the beginning, all information concerning the building project is contained in the digital building model – from the draft to implementation – including all design details, desired materials, fire protection requirements, acoustic properties, insulation and building structures, and administration. This constitutes considerable added value for all stakeholders compared to the old standard model, which was purely 3D. Thus, this improvement ensures more than just seamless collaboration between all those involved. The complex project can be turned over to the municipality – the proud building owner – with the required quality, on time and within the specified budget.

Hasselt City Hall is groundbreaking – in terms of design, planning and project implementation.

Independent and yet consistent

Steven Hendrickx, the head architect in Hasselt, recognized four decisive factors with Open BIM over the course of the successful project:

  • Individual partners design their model with their preferred BIM software, and with their own templates. Outstanding collaboration is ensured, though, thanks to a common, uniform standard which is specified in advance.
  • The division of labor is defined at the beginning of the project. Data on statics, for instance, have an essential impact on the architecture and structural design. Data on heating, ventilation and air-conditioning, on the other hand, are also important but don’t generally flow directly into the architecture. These data, for example, can be sufficiently analyzed with the BIM solution for quality assurance from Solibri.
  • Design changes in one area don’t necessarily affect the plans of all the others involved in the project. The architecture and the building stage are inherently the most closely linked.
  • The expertise of the staff, i.e., extensive holistic knowledge of the various building disciplines, is also critical for the success of the project.

Two examples of the advantage of precise planning

In Hasselt, the construction company was commissioned with excavation, among other tasks. An assessment of the amount of sand that needed to be removed was done based on a cal culation using conventional 2D planning methods, which yielded a result of 800 cubic meters. The engineers used the Solibri Model Checker based on Open BIM and the data provided by the architects and arrived at a figue that was just half this amount, i.e., 400 cubic meters of sand. This shows how exact the work with Open BIM solutions can be.

The steel struts to be installed are another example: With the interface function IFC Exports from Allplan, it was possible to use the BIM model to automatically calculate which steel struts needed fieproofing. All it took was a mouse click to obtain precise results, right down to the running meter. In projects that don’t use Open BIM solutions, these calculations are made by manually entering the data from 2D drawings in Excel or some other software and then recalculating and evaluating the data for use in quotations and planning, a process that is susceptible to error and one that leaves a lot of room for interpretation. These errors often go undetected until the actual cost planning is already completed. In the case of the Hasselt City Hall,  it was possible to avoid such errors from the outset.

Converting to Open BIM pays off

As is the case with any change, it takes a certain amount of time for companies and employees to accept BIM as the norm. The best way, according to Steven Hendrickx, is to start out by planning smaller projects using BIM. The experience thereby gained will make it possible to complete successively larger BIM projects. The advantages of collaborating through Open BIM are obvious: The entire workflow is much simpler for all project stakeholders, and building projects are completed within time and cost budgets.

CONCLUSION

Consistent standards and open interfaces in par-ticular are essential for successful building projects. Stakeholders need solutions that can “work together” for all and any individual tasks being performed. Seamless collaboration between humans and machines: This is ensured with Open BIM, and backed by the brands of the Nemetschek Group.

Lighting for Music Royalty

Profiled Firm: Nick Whitehouse

Location: Los Angeles, California (USA)

Nemetschek brand involved: Vectorworks

While the names Justin Timberlake, Jay Z, Coldplay, Beyoncé, and Britney Spears conjure up images of incredible concert experiences, the lighting designers behind such great shows are often an afterthought. But that's just how Nick Whitehouse likes it. "I want people to enjoy the music and the artists, to walk away saying 'wow, that was a great show,' not 'wow, what great lights,'" he says.

Regular concert goers never know how much goes into our designs because they blend seamlessly with the music, but people in the industry are always stumped at how we do it.- Nick Whitehouse, Creative Producer & Lighting Designer, Illuminate Entertainment Inc.

It's true that world-renowned lighting designer Whitehouse creates awe-inspiring light shows for some of the biggest names in music, but his current prominence within the industry belies his humble beginnings. He worked as a stage-tech while attending Notre Dame College in Leeds before pursuing a career in sound technology. Programming primarily at small venues, he made connections with as many people as he could. Eventually, one of these friendships led to an opportunity to work with lighting, and Whitehouse jumped at the chance, later building enough experience to garner the attention of major acts. His first touring experience was in 2000 with Britpop band Starsailor, which was, at the time, a rival of the British rock band Coldplay. Starsailor didn't have the same meteoric success as their contemporary, but Coldplay took notice of their competition's lighting designs and invited Whitehouse to join them for what would become eight years of touring.

An Almost-Missed Opportunity

Coldplay's success took Whitehouse around the world, and it was during one of the band's shows in Tokyo, Japan that he landed one of his biggest opportunities. American singer and songwriter Justin Timberlake was in the audience one night and was so impressed with the show that he offered Whitehouse a job on the spot. But because Whitehouse was committed to Coldplay, he turned Timberlake down. For the remaining four months of Coldplay's tour, Whitehouse thought he'd made the biggest mistake of his life. Luckily, he received a call from Timberlake's manager two days after the tour ended, asking if he was still interested in lighting Timberlake's arena tour of the FutureSex/LoveShow. "Obviously, I got on a plane right away," Whitehouse says.

Whitehouse and Timberlake subsequently developed a collaborative relationship that allowed the duo to explore new lighting techniques and test various set options. For example, when Timberlake's 20/20 Experience tour kicked off in 2014, it incorporated a moving bridge, new laser systems, as well as integrated video projection. During one part of the show, Whitehouse made it appear as if holes were opening up along the back wall of the stage. The effect was so realistic that many people asked him how he coordinated the feat, to which Whitehouse could only respond that it was an illusion. In reality, this visual treat functioned like a large art installation that revolved around a 150-foot wide by 60-foot high hexagon wall and overhead hexagon ceiling, which combined to provide a giant projection surface for video content.

The tour also challenged Whitehouse to reconfigure his design to fit varying arena sizes. "Between all of the promo shows and the tour dates, we did over 140 shows," says Whitehouse. "Most of them had different stage sizes and shapes, so every night we needed a different look and a different design. It kept me very busy. When I finished the tour, I think I'd only been home a total of 10 days the whole year."

Every Light Should Be an Instrument

His dedication positions Whitehouse as a sought-after lighting designer. "I'm there to interpret what artists want. It's their show." Understanding a client's needs is the trickiest part about his work, so Whitehouse strives to match his lighting to an artist's unique style, even when lighting for multiple artists in one show. He recalls that designing Jay Z and Justin Timberlake's joint Legends of the Summer tour was challenging because Jay Z wanted a stark look while Justin sought a visual element to correspond to every beat in his songs, as if the lights played the music, which required 12,000-15,000 lighting cues per show.

To achieve these diverse, visual looks, Whitehouse engages in a dialogue with his clients to ensure that they're satisfied with the general aesthetic of the lighting design. "I start drawing rough ideas on paper, and then I bring everything into Vectorworks® Spotlight software as symbols to make sure it all fits. This is where the software is very useful because you can maneuver things to fit in different venues, from large arenas like Madison Square Garden to the small stage on television's 'The Tonight Show with Jimmy Fallon,' while accommodating things like fire exits, jumbotrons, and seating configurations."

He adds that being able to work in 2D and 3D environments with hybrid symbols means he can very quickly see what works in terms of space and create a very nice looking plot at the same time. "Labeling and keeping track of fixture types, quantities, and focus positions is also a breeze with the comprehensive Spotlight tools. I can then position Renderworks® cameras in different seating blocks or camera positions and guide promoters through exactly what the sight lines to the stage will be from any seat in the house and tweak the design to help them maximize sellable seats in every venue."

Once the sizing is correct, Whitehouse uses the software to generate quick 3D renderings and get general feedback from an artist. After the client signs off on the 3D model, he dives into the technical process, exchanging information with set designers and construction companies through file exchanges to create the final light plots, which he then exports into a grandMA2 lighting console using a plug-in created by MA Lighting for Vectorworks software.

The plug-in takes all the fixture information contained in the Vectorworks file, including fixture type, identity, addressing, and 3D positioning. It then builds the MA2 show file, patch, and MA3D visualizer environment automatically – exactly as it is on the paperwork – a process that used to take many hours. From there Whitehouse works with the MA2 and MA3D to virtually program the basics of the show, safe in the knowledge that the console files, light plots, and eventually the real lighting rig all reference the master Vectorworks Spotlight drawings.

Illuminating the Future

Even though Whitehouse has a large repertoire of technical skills and a practiced, collaborative workflow, his design philosophy revolves around the idea that less is more. "When designers compete to be the brightest in every show, people's eyes get tired," he says. "You have to take a step back and let the artist shine."

Focusing on the artist is Whitehouse's favorite part of the job. "Music is central to what I do, and I love that what I contribute helps people enjoy a band or artist that they're seeing even more." And just like the artists, Whitehouse gets nervous every time he tries something new. "I've done so many shows that I understand the pressure performers are under. Sometimes when I try something new, I'll stand in the back of the room with my eyes closed and my fingers crossed," he jokes. "You can rehearse all you want, but the real testing ground is the show itself. Sometimes new bits of technology don't work, but if you never try, you'll never know."

Whitehouse's combination of exceptional timing and a passion for music ensures his clients get artful, visual elements that portray the feeling behind the music. And he's always willing to experiment with new design elements, which will similarly ensure his continued success.
