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.

Creating Welcoming Spaces for Everyone with BIM

Profiled Firm: ROJO Architecture

Location: Tampa, FL (USA)

Nemetschek brand involved: Vectorworks

For designers at ROJO Architecture, working in a space that's suited for play provides just the right mental break to spark their next great idea. Their office sits inside of what was once a busy shopping mall until a recession forced commercial building owners to rethink the space. Cofounder and Principal Rob Glisson enthuses that while the spacious, 25-foot hallways are perfect for throwing footballs, the real benefit of the structure's openness is how it facilitates collaboration. "Anytime you have something to offer to make a project better, you're expected, and able, to do so," he says.

It's this drive to work cohesively that allows Glisson, along with Cofounder and Principal John Saldana and a team of seven other architects, to respond to the medical, religious, commercial, hospitality, and private-sector clients they serve. "We're really working for our clients' clients and responding to their needs and desires," notes Saldana.

"We don't necessarily bring a style to the job as much as we let the job bring a style to us, and then we focus on doing that correctly."
- John Saldana

From Retail to Healing: A Space Transformed

One example of ROJO's focus on end users is its conversion of a 27,550-square-foot bookstore into a space conducive to orthopedic care, education, and research for the Florida Orthopaedic Institute. Because the site was once a large, open space with little privacy and no natural light, ROJO was challenged to meet the functional needs of the medical facility, as well as transform the entryway into a welcoming destination.

The result of their efforts is a space that patients and employees are happy to enter because it replicates the vibe of an upscale hotel lobby. The experience begins with a glass wall, featuring a cascading waterfall behind the facility's nameplate. This striking focal point wasn't meant to be an interactive water feature, but people touch this playful design element every day, creating a memorable, if unintended, experience. From there, a winding path cuts through the space, using sophisticated gray and gold carpet that complements wood-lined walls with recessed shelving featuring artwork, as well as plush upholstered furniture with modern industrial lighting.

As an early embracer of technology, ROJO has employed Vectorworks® Architect software as a Building Information Modeling (BIM) authoring tool for several of its projects, including the Florida Orthopaedic Institute. The firm modeled the design right in the software from the start, often adding far more detail than necessary for initial client signoff. This approach proved to be beneficial. "The better we can show our designs, the better we can sell them," says Glisson. "And it works." With fully developed presentations, he adds that their client meetings are 95 percent successful.

Saldana remarks that operating in a BIM workflow also reduces the firm's backend work significantly, saving hundreds of hours. "Even though clients often look at 2D drawings, we have everything backed up in a 3D model. We know a lot more about their space than it appears." ROJO also encourages its contractors to use BIM. "Precise quantities can save 10 percent on wasted materials," says Glisson. "Passing these savings along to clients clinches more bids. It's a win-win for all."

Affordable Housing Meets Hip Design

ROJO recently oversaw another transformation with The Portland building, which represents a departure from the typical affordable housing block. This government-funded, 78,000-square-foot project features 12 stories with 68 units, all on a small lot in St. Petersburg, Florida. ROJO's interpretation of Portland, Oregon's seaside cliffs are displayed on the face of the building and its elevator tower, with striations and a peeling of the exterior to reveal rich blues and greens in the glass and metalwork. The tower draws the eye upward with diagonal lines that change the shape of the windows as they ascend. Inside, reclaimed barn wood laid horizontally on the walls, modern black and white leather furniture, and magenta and black spotted carpet set an upscale, modern tone. And in a nod to Portland's claim to being the "City of Roses," larger-than-life sculptural rose cutouts appear to climb the outer walls of the building, showing expansive ocean views. "We really concentrated on what every person's experience was going to be. Most people are generally very surprised that it's affordable housing," Saldana says.

One challenge ROJO faced during the project's evolution was the lot's small size. Exploring different scenarios in Vectorworks Architect software proved critical to optimally sizing the space, including its three levels of parking. "I don't know how we would have done the vertical stacking without a tool like Vectorworks Architect," Glisson says. "We needed to evaluate if certain geometries were going to be more conducive to the unit placement. The software confirmed our design decisions and saved us an incredible amount of time."

Saldana also credits the software's presentation capabilities for enabling the project's smooth approval process by the State of Florida, the City of St. Petersburg, and a private developer. "We're only as good as we can communicate to the client, and Vectorworks Architect helped us communicate our ideas effectively."

A Bright Future with BIM

Looking ahead, ROJO's founders envision BIM playing an increasingly larger role in streamlining their workflows. For example, Glisson asserts that as subcontractors develop BIM models for their millwork, HVAC, and other products, construction details are rendered moot. Architecture firms like his can therefore work with the subcontractors and contractors directly. "We don't need to create a BIM model and then have them BIM again," he says. "The subcontractors can just BIM their work first and bring it back into our model. That's going to be a lot of fun to work with." How soon can everyone get there? Glisson and his team hope to leverage their experience with BIM to help the contractors they work with make process improvements within five years.

Saldana also sees huge timesaving opportunities with more prevalent BIM. "Contractors can input our model into their shop drawings. Then, we can put 100 percent of our time into the design, rather than documenting and drafting, and provide more accurate bidding." That sounds like progress for everyone.
