Realistic Simulation Supports Expansion of the London Underground

By Akio

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and construction on all BSSU sprayed concrete lined (SCL) tunnels.

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.

Spotlight on 3-im: Bringing a World View of BIM to Italy

By Akio

 

Edmondo Occhipinti founder and Director of 3-im

In some ways Edmondo Occhipinti, founder and director of BIM consultancy 3-im, is starting from the ground up—again.

Occhipinti spent more than eight years with Gehry Technologies, working from his role as a consultant to ultimately manager of the company’s European and South American divisions.

During that time, he grew from an individual with strong technical knowledge of 3D technologies to a manager who taught others how to apply these tools.

Now, in his new role with 3-im, Occhipinti is teaching a whole new group of players how advanced modeling can solve some of the most complex challenges facing the AEC industry.

Tech-Created Challenges

Many of these challenges are created by the technology tools used most widely today.

For example, on the project management side, one of the greatest problems Occhipinti sees is the fragmentation among systems.

“Every single department is on its own system,” he explains. “There is no integration among planning, procurement, etc., and everything is spread out on a thousand different documents that are really not connected at all.”

This fragmentation leads to problems in communication, errors and emailed updates that are outdated almost before they are sent.

Then, there are issues of scalability.

Many façade contractors already are using 3D technologies. The challenge, however, is finding a scalable solution that allows them to grow their business beyond one scope. Products suitable for coordinating the sizing of 300,000 cladding panels haven’t always been able to handle the highly detailed engineering of smaller components — or smoothly interface among these details.

3-im, a Dassault Systèmes partner, has heard time and again the surprise of clients who realize a solution already exists that can improve coordination among trades and components.

A New 3D Market

That surprise often comes because the Italian industry is relatively new to 3D design possibilities.

The country is home to some of the strongest construction companies in the world, particularly in the field of infrastructure. Many of these players have branched out worldwide and have led to the rise of smaller supporting players.

The painful irony, however, is that many of these companies are struggling in the regional market, even as they grow internationally, due to the ongoing economic crisis inn which Italy is mired.

It’s within this unique contradiction that Italian contractors are beginning to ask about 3D technology. Occhipinti notes that as a result of these economic forces, Italy has been moving much slower than some of the Northern European countries into its use of technology tools.

“What we’re seeing is these companies that are now technically very strong, but technologically very weak,” Occhipinti says.

That is about to change.

A Partner in the Process

Because many of these contractors have offices around the world, these Italian companies are comparing their capabilities to joint venture partners that are prepared to bid on projects requiring 3D delivery.

This recognition is leading many regional projects to seek out partners such as 3-im.

“They are looking at partners in Italy and thinking ‘if I want to get more competitive abroad, where my main market is, I need to be able to compete with the others and bring myself to another level. How do I do that?’” Occhipinti has found.

It’s a question that 3-im is well suited to answer. The company is made up of Italians whose careers have been built on technologically complex projects entirely outside of Italy. Since arriving in Italy in 2013, the company has established work with several major contractors, and is setting out to wow the rest by way of example.

A Complex Example

Among those examples is 3-im’s current work with Morphosis Architects on the San Donato Milanese headquarters of Eni S.p.A., the Italian oil company with worldwide operations.

The 117 million EUR complex will feature three buildings covering 120,000 square meters. Each building will be connected by various platforms. The double-skin façade is designed with a level of geometric complexity that made 3D design a near necessity.

During its design development, Eni decided to implement a BIM process for the design allotment, construction documents and tendering process. “It was looking for a partner that had the experience to run this particular process,” Occhipinti said.

At the start of this project, 3-im found a partner in Dassault Systèmes, finding the company’s 3D technology the perfect product for defining the scale and complexity of the Eni project.

For nine months, 3-im experts have worked to build a dense 3D model for the project, bringing it to LOD 350, which not only represents the shapes and sizes of specific object, but also the interfaces among building systems.

Occhipinti explains that using 3D helped ease three key areas:

  • Coordination of systems: 3D allowed 3-im to model the work of the different trades that would be involved. Occhipinti notes that many basic 3D programs would not have been enough to handle this coordination — because of the changes that were happening on an almost daily basis.
  • Geometric complexity: The double-skin can be complex to fabricate on its own, but this one employs some fairly unique geometry. In addition, each entry is made up of a double-curvature glass reinforced concrete panel that will ultimately be carved one by one due to their individual designs.
  • Data structure: The model was structured so that all of the necessary materials and specifications, and all of their information and features, was included and could be effectively pulled out of the model as needed. This not only proved helpful with scheduling, but with cost control.

A Fresh Opportunity

Despite the challenges facing Italian design and construction companies, and their partners around the world, Occhipinti sees major opportunities.

“We are living in an extremely complex moment where the global economy is shifting from one phase to the next, and this shift is a great opportunity for every industry to think about itself and propose new ways of improving processes,” he says.

As he points out, the construction industry is infamous for its inefficiency, so at this point there are no wrong answers — except for maintaining the status quo.

“Things like this don’t happen quickly,” Occhipinti adds. “When I started in this industry more than ten years ago, people were saying ‘in five years BIM is going to be standard.’ Five years later we heard the same thing. Things take time to change — and that’s good for us. We have the time to bring new value to the market.”

The Living Heart Project: Remarkable Progress Achieved Through a Common Goal to Improve Cardiovascular Disease Outcomes

By Helene

LHP-zSpace-Demo-Zygote-Heart-hi-res_600

Steve Levine, Chief Strategy Officer for SIMULIA Dassault Systèmes, is passionate about bringing cutting edge technologies from different disciplines to doctors and the patients they treat. In a recent recorded presentation at the 3DEXPERIENCE Forum in November 2014, Levine outlined the need for utilizing these technologies to build better human anatomical models, stating that 95% of all medical devices released to the public have never been tested on the human body.

The Living Heart Project was launched publicly in May 2014 to develop the world’s first realistically functioning computer model of the human heart. This project has made tremendous progress, and the video referenced above includes Levine and Dassault Systèmes President and CEO Bernard Charlès announcing a 5 year collaboration with the Food and Drug Association to develop cardiovascular testing paradigms.

The Living Heart Project relied on Dassault Systemes 3DEXPERIENCE platform to bring together more than 100 cardiovascular specialists from 30 organizations to develop and test the model. In the video, Levine commented that at the outset, bringing together researchers, doctors, medical device companies, and regulatory agencies was a challenging task as information is siloed. The 3DEXPERIENCE platform allowed the specialists to crowdsource the heart model, with each bringing their expertise without sacrificing intellectual property.

The video shows impressive visualizations of The Living Heart model that are, pardon the pun, heart stopping. Levine points out in his presentation that it is the first four chambered 3D heart model that is based on commercially available, validated technology. He also showed that the model can be viewed in different ways, highlighting mechanical stresses important for indications such as heart failure as well as visualizing electrical conductivity which is important for studying heart arrhythmia. Levine also showed how collaborations within Dassault Systèmes were instrumental to visualize The Living Heart in 3D, as a “walk in” model. Additionally, 3DEXCITE provided true to life coloring and features to aid medical students and surgeons.

Levine went on to tell the story of Emily, a girl born with a heart that is literally “backwards,” with right and left ventricles transposed. As the earlier 3D models Levine showed in the presentation illustrated, the heart is not symmetrical, so this defect has caused Emily to have 4 pacemakers by the age of 20. In May 2014 an animated video showed Emily’s story and how the The Living Heart would help diagnose and treat her. Emily’s story is particularly touching for Levine to relay, and the reasons are best explained by him, so we encourage you to watch the entire video of his talk to learn why.

Levine talked about the collection of resources available at 3ds.com/heart which helped to describe the vision of the Living Heart Project to collaborators and to illustrate their progress.  He sees the project as a model to unite other healthcare specialists, medical device companies and regulatory bodies to collaborate around aspects of human anatomy or disease models. The 5 year collaboration with the FDA will increase the number of participating organizations from 30 to 100 and will continue to involve the Medical Device Innovation Consortium of which Dassault Systèmes is a key sponsor.
