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.

Revitalizing the Space "Where the Waters Meet"

For the Australian landscape architecture and urban design firm McGregor Coxall, a design has to be more than just a quick solution to a client’s existing problem. Realizing that approximately 70 percent of the world’s population will live in cities by the year 2050, Managing Director Adrian McGregor is clear that the built environment should respond to the needs of today, as well as prepare to combat issues that the population will face in the coming decades.

“I’m passionate about the challenges that human beings are facing globally in terms of our environment, and I want to help cities grow in a sustainable way.” - Adrian McGregor

McGregor’s firm therefore uses design to bridge the gap between environment and development, and takes a multi-disciplinary approach to innovation and research-based project solutions. One example of how McGregor Coxall furthers their endeavor to build a more sustainable world is with one of their recent projects, the Parramatta River Urban Design Strategy.

Modern Parramatta, an Australian Aboriginal word for “head of the waters,” was founded in 1788 as a farming settlement that provided food for the growing urban port of Sydney 23 kilometers downriver. While Sydney’s metropolitan area grew to encompass Parramatta, the locale did not diminish in importance. Today, the Parramatta City Centre is Sydney’s second largest Central Business District (CBD) and the only one located on a riverfront, presenting a distinctive mix of opportunities and challenges for its development.

McGregor Coxall’s Urban Design Strategy for the 31-hectare space is meant to reorient the district toward the river, connecting it to the Circular Quay area by ferry and positioning Parramatta Quay as the new water arrival point at the place where the Parramatta River runs into Sydney Harbor. The strategy aptly rebrands the location “Where the Waters Meet” and aims to revitalize the CBD through an innovative urban realm and four dynamic, mixed-use precincts along the water’s edge. The design creates an active waterfront where the city can celebrate its public life.

Urban Development Meets Environmental Consciousness

The firm analyzed the area’s heritage items and cultural assets, as well as its open spaces and ecology, in order to create a design that would incorporate both the urban and environmental needs of the Parramatta City Centre. The district is currently experiencing economic, demographic, and physical growth, so one of McGregor Coxall’s main goals was to create a space that engaged the public and encouraged pedestrian travel. To accomplish this, the firm designed the new waterfront commercial district within the river’s flood zone, bringing it close to the water level to create activation inside the Parramatta flood corridor.

Using flood resilience concepts working successfully in Hamburg, Germany’s HafenCity, the design team created walkways, termed “Water Streets,” that connect the urban areas of the city to the riverfront. These Water Streets will integrate public art, water sculpture, and water-sensitive urban design initiatives. Once city-goers reach the river itself, they’ll find a variety of public spaces for events, recreation, shopping, dining, art, and culture, as well as easy access to the pre-existing attractions of the area. New medium-rise apartment buildings will also allow for community growth within the city center, contributing to the expansion of the vibrant area.

McGregor Coxall’s community-centric approach means that they don’t simply keep the end users of their projects in mind during the creative process; rather, they engage with them to produce more informed designs. This means that while the official client for the project is the city government, the firm consulted with the people of Parramatta to understand what they wanted most from their riverfront. “We’re working with the community and the stakeholders to create a very broad, deep conversation with the city as a whole,” says McGregor. “It’s allowing us to deliver what I think is going to be an important and fantastic project where landscape architecture is shaping the urban environment. We even developed our own web software called ‘yourplan’ to engage with citizens and communities on our projects.”

McGregor Coxall matches the value they place on public feedback with their dedication to environmental sustainability. The Urban Design Strategy incorporates many precinct-scale green engineering elements that will help the area thrive into the future, making it resilient to the effects of climate change and encouraging ecological growth. The development of the riverfront is designed to withstand flooding of up to three meters to accommodate sea-level rise.

The plan also calls for the movement of existing weirs and quays in order to shift the location of where the freshwater of the Parramatta River hits the saltwater of Sydney Harbor, which works to restore and improve the aquatic ecology of the area. The design further enhances the river’s ecosystem by introducing water cycle management and water-sensitive urban design. The strategy calls for restoring a natural form to the connected Brickfield Creek channel outlet by creating vegetated banks, incorporating stormwater treatment systems on both sides of the river, and capturing storm- and wastewater for non-potable purposes in the new developments. Designers at McGregor Coxall understand that while a design’s aesthetic is important, so is its environmental impact. McGregor notes, “there’s a commitment to the quality of the work that we do and also to the legacy that we leave.”

Making an Impression Around the World

McGregor Coxall has indeed made a name for itself in the landscape architecture and urban planning industries, completing over 300 projects across Australia, Europe, and Asia. Their work has earned more than 60 awards, including the prestigious Topos Journal International Landscape Architecture Practice of the Year, landscape’s highest international prize, which honored McGregor Coxall as a proponent of a new wave of environmentally focused landscape architecture, framed within a modernist design approach.

Their work on the Parramatta River Urban Design Strategy earned the firm several distinctions including the Australian Institute of Landscape Architects’ New South Wales Chapter’s Award for Urban Design, as well as the Planning Institute of Australia’s National Award for Urban Design; the Australia Award for Urban Design: Policies, Programs and Concepts - Small Scale; and the Prime Minister’s Australia Award for Urban Design. To achieve such international acclaim and local distinction, McGregor Coxall relies on the 3D modeling and site design tools within Vectorworks® Landmark software.

“We’re really happy with the ability to model large scale environments in Vectorworks and then move into detail with the same software program, allowing us to develop very complex and large 3D documentation packages, create planting plans, and generate worksheets from those plans in order to specify quantities and material takeoffs,” says McGregor. “I also like its graphical abilities. I love that we can use textures and gradients to create really great looking sets of drawings simply through a graphics process.” The firm also uses Vectorworks Landmark software for its extensive geographical information system (GIS) capabilities. “We do some very large projects in terms of sheer physical size, which requires us to import a vast amount of GIS data and can become extremely complex. Landmark lets us incorporate all of that data easily, so that we can focus on design.”

McGregor sees design software as more than a tool to create the built environment; it’s also a way to more efficiently and accurately protect the planet. “I think that one of the great global trends that we have now is a shift toward low-carbon economies where there’s a price on the carbon that’s released into the atmosphere, so it has a value,” he says. “Carbon is now traded as a commodity, and it is unlocking a global market for new renewable energy technologies. Cities are in a rapid state of change that is as big as the Industrial Revolution. The software we use has to be intelligent in terms of our carbon footprint modeling. With intelligent BIM, smart symbols, and coordinated worksheets, Landmark gives us the ability to make this happen.”
