BIM projects need more than just 3D software At Bentley we appreciate BIM processes need more than just 3D design software to deliver a successful civil project. Parsons Brinckerhoff and Arup JV used Bentley software to design, analyse, simulate, and collaborate on the AUD 5.6 billion Brisbane Airport Link upgrade. The combination of Bentley’s road, bridge, geotechnical, and project collaboration software helped complete the BIM-compliant project in record time.

Now that’s what we call a civil partnership.

News Asta Powerproject BIM enables users to link project plans and 3D models

Asta turns to the cloud for 4D planning sta is focusing on affordable 4D planning by combining 3D planning and scheduling in Asta Powerproject BIM. This latest version of the project management software Asta Powerproject will enable users to link project plans and 3D models in a single, cloud-connected tool and share information using the IFC4 format. The software uses Eleco BIMCloud, from Asta parent company Eleco, to share information. From within the application users will be able to access its core project management, scheduling and resource management capabilities and draw on the functionality of other products from Eleco.

ROUND UP 3D scans in SketchUp

According to Asta, the software will enable users to: generate a master project plan and schedule directly from an IFC4 model; link objects in an IFC4 model to specific tasks in the schedule; create and play a 3D visualisation of a build along its timeline, linked to project milestones and baselines; share and exchange information with compatible applications (including Autodesk Revit, Arcon and Bidcon) via the Eleco BIMCloud; and maintain a real-time 3D view of the evolving building throughout the project, reflecting changes from model to schedule and vice versa. ■ astadev.com

kubit links from real world to CAD ubit, a specialist in surveying, laser scanning and as-built documentation software, has released new and updated products for Autodesk’s 2015 software.

BIM in the cloud While many firms wrestle with getting their BIM workgroup implementations working on desktops in an office, one company is aiming to revolutionise collaboration by moving the BIM data to the cloud. by Martyn Day

e all know that Building Information Modelling (BIM) is a hot topic and is now being backed up with increasing numbers of adopters, assisted in the UK with an impending government mandate for its own building projects. While there are many advantages to the deployment of modelling technology, one aspect that is currently being lauded are its benefits to collaboration within design teams and project participants, in federated and highly disconnected building industries. Unfortunately, this advantage has still yet to be truly realised, partly for cultural reasons, but also for some serious technical ones. Nearly all BIM modelling applications were designed primarily as solo seats, for so-called ‘lonely BIM’, with very

little consideration that there may be five, 10 or 200 seats working collaboratively on a single model or project. BIM severs, such as Autodesk Revit Server, are relatively new and will usually only work with one vendor’s BIM tool and proprietary format. Significant data incompatibilities between vendors’ proprietary BIM formats and the huge file sizes of BIM models have not helped inhouse or wide-area collaborative working. This can be a massive problem, even for experienced BIM users who have to patch together their own technology stacks from an array of applications. The best implementation of a BIM workgroup server that AEC Magazine has seen comes from Hungarian developer, Graphisoft and its Teamwork product, which was first released in 2009. While

limited to managing ArchiCAD modelling sessions, the company has produced an easy to deploy server that runs on a local machine and operates over LAN or WAN networks. Users can visually select geometry to reserve for modification, with built-in instant messaging. This level of granular access means only small amounts of data (measured in Kb) are sent over the network in an editing session. Teamwork also provides a management layer with allocation of roles and access with reports. Graphisoft recently took the next logical step and announced that it is taking this capability to the cloud.

Big in Japan For the launch Graphisoft, which is based in Budapest, chose to hold an event in

ArchiCAD 18 preview It may not be a coincidence that BIMcloud has arrived at roughly the same time as Graphisoft’s yearly update to its flagship BIM tool ArchiCAD, which of course comes BIMcloud ready. AEC magazine will review ArchiCAD 18 in depth in the next edition but here are a few of the new features to whet your appetites: ArchiCAD 18 offers a number of ‘bundled’ technologies across its existing brands, a lack of which has been criticised in the past.

It has a built-in Cinema 4D rendering engine. This offers easy one-button “photo-shot” rendering without the need to tweak sliders and parameters, all the way through to full-interface and capability professional usercustomised rendering within ArchiCAD. ArchiCAD 18 features revision management and automatically documents changes to the building model. It tracks the who, why, what and when throughout the

entire 3D BIM to 2D documentation workflow. Pushing open standards, Graphisoft has added support for buildingSMART’s BCF (BIM Collaboration Format), which is an XML schema for collaboratively sharing data. ArchiCAD adds mark-up entries into its BIM models following the BCF data structures. To date, Tekla Structures, Solibri Model Checker and DDS Architecture all have built in support for BCF.

Tokyo express Prior to the launch event, Graphisoft took the press corps on a tour of significant buildings in Tokyo, together with some face time with clients Nikken Sekkei, to discuss its approach to Building Information Modelling (BIM). Walk down any main street in Tokyo and it is pretty obvious that the Japanese love modern buildings, glass, steel, concrete, seemingly impossible curtain walls with an aesthetic that is pleasing to the eye. Our first stop was the Iidabashi station commercial buildings by Nikken Sekkei, which was undergoing final fit and finish. A journey to the top of the skyscraper gave amazing views over the incredibly dense city of 13.23 million people, seemingly stretching to infinity. The BIM manager from construction firm Maeda gave us a brief overview of the company’s ongoing drive to migrate to an end-to-end BIM process. Next up was the Jimbocho Theater, another Nikken Sekkei design, which looked like something out of a Manga cartoon. Oak Omotesando, is an Obayashi and Tange Associates refurbishment and retrofit retail project. It was completed in ArchiCAD and stands next to the equally stunning reinforced concrete and steel framed TOD’s glass and concrete building by Toyo Ito & Associates. Tod’s is wrapped in a skin of criss-crossed concrete braces and glass that mimics the trees lining the street in Tokyo’s Aoyama district. Prada’s Herzog & de Meuron store has to be seen to be believed, looking more like latticed jewelry than a building. The six-storey, fivesided, building has signature diamondshaped glass panes, which vary between flat, concave and convex ‘bubbles’, which result in smooth curves throughout its interior. Businesses in Japan clearly have an appetite for experimentation and modern design. It is no wonder that the benefits of using BIM modelling and analysis is seen as such a priority to all its major AEC firms.

increasing number of users and / or size of models / model complexity. Running on a public hosted server, such as Amazon Web Services, BIMcloud dispenses with most of the set-up complications and bottlenecks with all data being hosted in the cloud. It is managed via a new BIMcloud administration tool for creating, merging, editing BIM servers with expanding resources. It also features access to automatic backups and version rollback, should you want a model to go back to a previous state. BIMcloud can also operate as a private cloud, using an in-house server as the storage destination, adding an additional level of security. It is also possible to work on models offline and synchronise with the server later. Graphisoft’s BIMx docs format supports the AEC process through its integrated 2D and 3D geometry and project metadata. It is very easy to use with a simple interface and provides navigation tools for desktop machines or mobile devices such as tablets (iOS and Android). Comparisons have been made between Graphisoft’s BIMcloud and Autodesk’s Revit and Revit Server product. One point of difference is ArchiCAD’s forward and backwards compatibility, a well-known Revit bugbear. Revit Server is a complex beast, requires a Windows Server, and lacks audit and permissions. Some CAD managers I have spoken with resort to using VPNs (Virtual Private Networks) for cross-Internet (and cross network) connectivity. With data being replicated all over, consideration needs to be paid to the network speed / bandwidth between each location. If the bandwidth is not enough, many managers deploy WAN accelerators, such as a Riverbed device to compress and decompress data on the fly. In comparison, it is pretty clear that Graphisoft is still well ahead of the competition on deployable workgroup tools.

Conclusion The launch of BIMcloud coincided with cherry blossom time in Tokyo. Perhaps an apt coincidence, as with all these technological advances and customer velocity that Graphisoft is fostering in the Asian market looks to be quickly bearing fruit. But good technology alone does not guarantee a win. The Japanese market for any CAD developer has been a tough place to compete, with strong local developers and very demanding customers. Graphisoft’s mature product is winning over large firms predominantly on its ability to work with customers, tailoring the product to the market. This is not happening at Graphisoft’s expense. Customers actively assist in funding research and development to help refine their BIM workflows and processes. Japan’s major construction firms are, step by step, moving in the same direction as the UK construction industry with plans to use their own BIM standards to compete on a global level. The Japanese ethic on efficiency and compliance should force this through its building industry much quicker than in the UK. I suspect less ‘cajoling’ BIM lunches and drinks events are required for firms to buy in! Graphisoft has managed to simplify BIM collaborative workflow. BIMcloud takes that to a whole new level while making it even simpler to deploy on a global scale. The Asian market is certainly in Graphisoft’s sights with Japan the first stop on its tour of this part of the world. As for the UK and North America, success in other countries is a slow burn way of raising national profile but we should be taking greater heed as to what tools competitors are using. Now, if Graphisoft could just build a BIMcloud for Revit, it would make a killing…. ■ graphisoft.com/bimcloud

Feature

Autodesk 2015 AEC Products Autodesk moves closer to becoming a services business and takes a leap from a 30-year-old upgrade cycle to a subscription only and rental model. by Martyn Day

New sketchy lines feature for Autodesk Revit 2015 enables designers to apply a hand-sketched graphic style to views of a model

utodesk has spent years perfecting its yearly release and upgrade cycle, managing to produce feature-rich upgrades up until the 2012 introduction of Suites. An Autodesk subscription is modelled like a club membership and moves customers from the perception of ‘owning’ software to paying to have access to services. It is a subtle but important change. The old upgrade cycle has now ceased to exist. Instead, customers now have the following options:

(analysis, rendering, data storage) and Autodesk is experimenting with cloudbased, web-accessed versions of its popular applications (AutoCAD, Revit, Inventor etc). In the near future, customers will be able to store data on the cloud and have access to professional editing or querying tools wherever they are in the world (that has Internet access), on multiple types of devices, including desktop, tablet or smart phone. According to Autodesk, the future is collaboration and server-based power.

• Maintenance Subscription, which subscribes existing licenses. Customers who wish to buy new licences will also be put on Maintenance Subscription

The AEC team has been very busy this year, both with products and web services and has introduced a number of new products and brand terms at the same time. However, in doing so, the company has sacrificed some product clarity and something tells me this is going to get worse before it gets better. As a general rule, if a product has ‘360’ after it, it is a cloud-based application, platform or service. If it has a year in the title, it is a desktop application. Some products are the web-based equivalents of the desktop version, for example AutoCAD 360 for AutoCAD 2015, however the cloud-based version may not be as feature-rich as the desktop, as of yet. Suites continue to be the main focus. Autodesk continues to sell Standard Premium and Ultimate versions and has not altered the bundles configurations too much.

Subscription • Desktop (rental). Customers stay on their current releases and then move to this term-based model for future products / updates • Cloud Service Subscription, which provides a selection of cloud-based services that offer access to visualisation and simulation as well as expanded mobile and collaborative access Autodesk firmly believes that customers will benefit from these services it provides through cloud computing. Desktop products have been updated to make use of its cloud-based functionality 14

2015 releases

Autodesk AutoCAD Design Suite 2015 has a new refined visual interface, enhanced point cloud support, and better ways to work with online maps. Autodesk Building Design Suite 2015 has enhanced integration with Autodesk’s BIM 360 cloud services, also benefits from better point cloud capabilities, and a raft of updates to Revit. Autodesk Infrastructure Design Suite 2015 includes major enhancements to the AutoCAD-based Civil 3D software, including: user interface, corridor modelling, more efficient profile layouts, more consistency between the AutoCAD Civil 3D and AutoCAD ribbon/command set, production drafting, and simpler ways to create custom sub-assemblies.

Building Products Civil3D is quickly being usurped by Infraworks as the development platform of choice for Autodesk. However, for now Civil3D remains a very popular product based on the world-dominating AutoCAD platform. Civil 3D 2015 sees the following improvements: • •

Greater flexibility for designing and displaying corridor models More efficient creation of profile layouts www.AECmag.com

20/5/14 12:06:25

• •

•

Better production drafting to create deliverables more efficiently More consistency between the AutoCAD Civil 3D and AutoCAD ribbon/command set Simpler ways to create custom sub-assemblies Streamlined geographic location functionality that includes the ability to capture and embed Online Map Data (e.g. aerial map information) for offline viewing and plotting Better interoperability and data exchange for DWG and DGN files

InfraWorks 2015 can be found in various editions of the Autodesk Infrastructure Design Suite 2015 and Ultimate edition of the Autodesk Building Design Suite 2015 as well as Autodesk InfraWorks 360, which offers additional cloud services that add collaboration and analysis for large-scale preliminary designs. InfraWorks 2015 and Infraworks 360 new features include: • •

•

New user interface for quicker access to the tools Support for additional data formats including AutoCAD 3D DWG, AutoCAD Civil 3D DWG, 3D DGN, IFC, and SketchUp (SKP) CityGML import now supports schema location, building asset mapping,

and self-intersecting geometry Roadway Design for InfraWorks 360 includes style zones within road sections and fixed width parametric grading for roads with discrete control over grading, cut slope and fill slope The new Bridge Design for InfraWorks 360 allows civil engineers to explore preliminary bridge design options more effectively by modelling and visualising realistic civil structures in the context of the surrounding proposed site. This new application helps simplify, accelerate, and focus the layout of girder bridge design concepts, and maintain consistent data and context

Autodesk also released technology previews for upcoming industry-specific applications for InfraWorks 360 including Drainage Design and cloud services, Model Builder and Corridor Optimisation.

Autodesk Advance Steel In October 2013 Autodesk announced the acquisition of key technologies from Graitec, including its popular AutoCADbased, Advance Steel solution. The first product to come out of the acquisition is Autodesk’s rebadged and updated Autodesk Advance Steel 2015 product. Advance Steel 2015 provides structural steel detailers, fabricators, engineers and contractors with a comprehensive suite of tools for 2D and 3D detailing of structural

elements, steel connections and plates. Advance Steel helps speed time to fabrication by automatically generating shop and general arrangement drawings, creating bills of materials, and producing CNC files directly from designs. In fact, Autodesk sees Advance Steel as a key tool to connect Revit and other Building Information Modelling (BIM) workflows from design and construction through fabrication. New features for Advance Steel 2015 include: • • • • • •

Integration enhancements with Revit and Navisworks New user interface New options for creating different model views of projects New tools to configure the software’s main settings Reduced rework on shop drawings for complex parts CNC data is now extended to complex parts, such as curved beams and polybeams. This data is fully articulated in the DSTV files automatically generated from the 3Dmodel

Revit 2015 Autodesk’s core architectural BIM tool gets a fair bit of love this year, with some useful new features that include a number of user requested upgrades across May / June 2014

Feature Revit 2015 enables users to create schedules that include imagery to convey graphical information for elements. These images will display when a schedule is placed on a sheet

Architecture, Structure and MEP, which are now provided as one product. The development team has looked at a broad range of capabilities that will benefit most users of Revit irrespective of what it is used for. The ‘Themes’ that focused development addressed the following topics: construction, analysis and simulation, scalability, interoperability and productivity. Revit 2015 new features include: •

• •

•

Hand-sketched graphic styles for lines in models, using the sketchy lines feature Include imagery in schedules to better convey graphical information Create and manage changes with improved tools to sketch and control revision cloud shapes Create more accurate documentation in 3D views using enhanced hidden lines capability

The hand-sketch feature is long awaited and really helps remove the rectilinear precision of CAD models, to give an artistic feel to both 2D and 3D views. This is great for client presentations and producing collateral marketing images. Industry Foundation Classes (IFC) have been improved, which is useful for interoperability or Construction Operations Building Information Exchange (COBie) workflows, with IFC maintaining the link back to the original models when imported into Revit, improving model updates. The import Application Processing Interface (API) has also been opened up. Lighting analysis for Revit models has been enhanced through the Autodesk 360 cloud rendering service. Now, using the power of the cloud, its possible to get plans with the lighting densities displayed, covering natural and artificial light. Autodesk claims this has been extensively validated and supports Leadership in Energy & Environmental Design (LEED).

Acceleration A second tranche of Revit features is scheduled for third quarter 2015. Codenamed Sundial, the update will focus on improving speed performance for Families, Energy Modeling, structural editing, constraints response, MEP system editing and Wall updates. There will also be improvements to the Family and View browser, structural element orientation, snapping and automated structural setbacks. Perhaps more importantly, Revit’s graphics pipeline is due for major www.AECmag.com

p14_15_17_AEC_MAYJUNE14_Autodeskhk.indd 17

improvements with Revit finally getting more out of GPUs, which will make use of workstation-class graphics cards to accelerate model interaction.

Retrograde Improvements Autodesk development teams are exploring the possibility of providing some of the new functionality in prior releases, for example making Sketchy Lines available in Revit 2014. That Autodesk is considering such a move highlights some of the problems with the transition from a traditional sales model to a subscription-based one. Many large AEC projects standardise which CAD system is used for all participants to ensure data integrity. This is doubly so for BIM modellers using Revit, as it is incapable of sharing data between different releases. With Autodesk removing upgrades and promoting yearly subscription, firms that are trapped on old releases of software will see little to no benefit for their subscription payments. If Autodesk is going to keep this policy, future releases of Revit may benefit as retrograde enhancements are planned in advance.

Conclusion As Autodesk continues to flesh out its AEC offerings, we expect to see improvements to conceptual design tools such as FormIt and Dynamo, through Revit for architectural, structural and MEP detail design. There are desktop and online analysis tools for clash detection, lighting analysis and sustainability, with new solutions for detailed structural documentation and fabrication. After the design process, Autodesk is also looking to provide digital solutions

for on-site layout and installation with BIM 360 Glue and Field. Autodesk has slowly been providing point solutions for all AEC project participants and it will not be long before it has critical mass. The biggest hole in the product portfolio remains the data management backbone. Autodesk has never really been strong in this area, having had multiple attempts, but has yet to develop anything to rival products such as Bentley’s ProjectWise. By changing its business model, Autodesk is taking a risk. While its upgrade practices were very unpopular with a lot of its long-term customers, the subscriptions and rental model has yet to be adopted by its customer base. Without full license sales, Autodesk will miss out on the ‘joining fee’ revenue. However, it should accrue longer-term revenue increases through the wider adoption of yearly and monthly usage fees. To ensure this happens Autodesk has to move from yearly product releases to incremental product updates, providing a broad spectrum of integrated systems. The product rental option will lower the cost of entry for new customers and offer dynamic expansion or contraction for existing customers. However, it also removes the main reason for staying with Autodesk products — maintaining the original investment. I expect Autodesk products will continue to increase their interaction with the cloud and will be updated at different times of the year. Customers will be faced with the choice of renting new licenses or paying and subscribing to them. It is highly likely that historical licenses will go on subscription while new licenses will be rented. Welcome to club Autodesk. ■

Comment

A BIM industry temperature check Excitech consultant Rob Clark was part of a committee that recently ran a workshop called BIM4Real to share and solve some of the problems real Building Information Modelling projects encounter. In this article he shares the findings and some personal thoughts.

IM4Real eschewed the tried and tested conference format by focussing on a fictional building project: the construction of a large shop in the English and Welsh border town of Shrewsbury. The completely fictional client had produced an Employer’s Information Requirements document in line with BSi PAS1192:2. Attendees were split into five groups and included people from different disciplines. Their task was to discuss how they would deliver this project as a team. There were three focused sessions: project set up; design delivery; and using the data produced to aid the construction and subsequent operation of the building. Five chair-people summarised at the end of each session what had been discussed. Each table was laden with documentation including industry protocol

documents and templates for execution plans as well as the Employer’s Information Requirements document. In each session, the chair-people were asked to get answers to very specific issues that face our industry in the delivery of projects using co-ordinated Building Information Models (BIMs). What came out proved very interesting. There was plenty of consensus, a lot of confusion and quite a few challenges.

Project kick off Despite years of under-utilisation the BS1192:2007 Code of Practice workflows were being adopted by more than half of the room. This is likely to be due to the natural standardisation of information that comes from adopting a Building Information Modelling process.

BIM4Real the event

BIM4Real was a collaboration between Ramboll’s Graham Stewart, Ray Purvis of Atkins and Excitech’s Rob Clark.

May / June 2014

p18_19_21_AEC_MAYJUNE14_Excitech.indd 18

The three industry experts were sitting in the keynote presentation at Autodesk University, when they realised that what they wanted from a Building Information Modelling (BIM) event was no longer what BIM was. They wanted evidence of what the industry is doing, what it cannot do, where the real challenges are and what is real best practice.

They thought the best way to achieve this was to get a lot of clever people talking to one another; to bridge the gap between strategy and delivery. So, BIM4Real was born: a workshop event without any formal presentations. Attendees included architects, engineers and construction managers, as well as clients and consultants.

Prior to the meeting I had expected a lot of conversation on liability, but interestingly there was a good amount of consensus that project indemnity covers these requirements. Where there was a lot of debate, however, was model ownership. Initially it was suggested simply that the ‘client owns the model’. This raised a lot of discussion over where the limitations of ownership occurred. There was concern that simply communicating such ownership would imply that it can be used without restriction, including on other similar projects. Model ownership, it was felt, is for the particular project asset alone. Apparently, a client saying ‘we want BIM, can you deliver?’ in the qualification is not really sufficient. I have to raise a smile at that rather obvious piece of common sense; however it is plain that a good number of jobs start with this very requirement alone. There was general acceptance that the new PAS1192:2 document offers good guidance for project set up, procedure and delivery for both the Project Information Model (PIM) and the Asset Information Model (AIM). The single Employer’s Information Requirements (EIR) document was seen as essential to the successful delivery of a project. A Digital Plan of Works was deemed necessary, including documented and agreed deliverables. This should include all necessary asset information, or indeed www.AECmag.com

required. So at BIM4Real we asked questions like ‘who owns the stairs?’ They have Architectural, Structural and quite probably Building Services elements. The idea of the question was to uncover people’s strategy to ensure collaborated or federated models do not end up containing duplicate geometry and of course, duplicated information. There was plenty of discussion, but no consensus as to how this issue should be approached on a project. Some suggested that the reason for this was software limitation and that cloud solutions would begin to resolve duplication, although I would argue that there must be a strategy nonetheless. Some suggested this was BIM Maturity Level 3, although that was contested. People did suggest this made a clear case for a detailed Matrix of Responsibilities to be developed. There was also a suggestion that this showed that Design Review meetings do not always involve the right people; that technical staff with knowledge of how to deliver models should be involved. This would give senior technicians an opportunity to speak with their counterparts from other disciplines and for them to agree how to approach the modelling collaboratively. It is important that the design leads, contractors, and clients are all in the same room for project design review in order for a collaborative project to work. Software geeks to talk to one another as well. Validation, a critical part of the handover process of a model to a contractor and also at data exchange points, is largely dealt with through peer checking rather than any kind of formal audit process. Looking at this from a risk perspective it is surely a concern? When we hand over a model to the contractors and fabricators, can they trust it for construction scheduling for example? Getting design delivery right is key to moving towards a truly collaborative design process. But we need to change the www.AECmag.com

p18_19_21_AEC_MAYJUNE14_Excitech.indd 21

ethos of how we approach it. There seems to be real momentum now and a good technical and strategic foundation of ability in our industry to realistically push for this.

Construction and operation There was a lot of talk about how models are effectively communicated, including the hot topics of OpenBIM via Industry Foundation Class (IFC) and asset registers like COBie. It would be nice to report that there was clear consensus on either of these issues, but it still seems to be a significant sticking point. It was hotly debated as to whether IFC is the right format for outputting models, with many raising trust issues. However, IFC was seen to be improving in both the understanding of it and what software can do with it; some suggesting that it is up to users to put pressure on software vendors to keep improving this workflow. I personally have mixed feelings about IFC and how well it moves information from place to place. If you are happy to really dedicate your time to understanding it, including the various mapping options for data, then you can probably do really well and deliver on expectations. Most people, however, just want to hit ‘Export’ in one software and ‘Import’ in another and the same model appears. Without significant expertise that is not guaranteed to happen at present, no matter what software is being used. It is unfortunate that in recent software releases there are countless options for export settings with no real way to test the import until it is sent to the recipient. As collaborative design becomes more open it would be naive to suggest that a single software vendor will be used on projects, or that vendor formats will be futureproofed for ongoing operation of buildings. We need to keep pushing our knowledge here and at the same time pushing the vendors to work collaboratively to make these

workflows more simple. The same is often said of COBie. The standardised data concept is fine but the idea of using spreadsheets is questionable. These are a cumbersome format not suited to allowing many people to edit or for handling large quantities of data. A consensus was formed that interference checking should have occurred prior to handover to the contractor, thus handing the responsibility for this to the Design Lead. However this suggestion caused a lot of argument. It was suggested that the BIM Execution Plan should make clear the responsibility of who is federating the model and who is conducting interference checking. That is not to say that the Contractor Lead should not continue this exercise as models are updated to reflect on-going site conditions. There was a suggestion here that the contractor and cost consultant should also be involved in the technical discussion to perhaps ensure that, as far as possible, models were created which are sympathetic to their requirements.

Conclusion All in all, the BIM4Real round table session did seem to raise more questions than it provided answers. That said, I think most people felt relieved that they were not being naive in any way by not understanding some of the key issues surrounding the delivery of projects. We, as an industry, should be able to address these issues and work together to resolve them such that we are able to move from the strategic direction to delivering more projects with increasing benefits through BIM.

Interview

The future of Rhino At the recent Shape To Fabrication conference Bob McNeel, CEO of Robert McNeel & Associates, was his usual straight-talking self when quizzed about the future of Rhino, including the Mac version, the cloud, parametrics and Grasshopper. Q: Are you busy working on Rhino 6? Bob McNeel: The answer is no; they won’t let me touch the code! We try to get something out in the field as soon as we have something that’s stable enough to use, and they’ve been working on since shortly after Rhino 5 came out. Of course there’s always service releases and other distractions to slow it down, but there’s been a lot of work going on — particularly on the back-end, on the parts that they want to overhaul, messy bits of code that have been there since version one, things like that, which you can’t do in the middle of a service release. There’s probably not anything that is earth-shaking in terms of brand new sparkly features, but at least we’ve got something that doesn’t tip over when you try to run it. There are a few people that want to get something out when we get back, I don’t know if we’ve got everything in place to do that yet, and I try not to make promises for things. Q How is the Mac version coming along? BM: This is another place where we need a little bit of expectation control. As some of you know, porting from one platform to another is a major project. Also, Rhino is a very deeply embedded Windows product; we use a lot of Windows resources. The tag line for the first 20 years was something like ‘Nurbs modelling for Windows’. So it’s been a bit of a chore to untangle a lot of Windows code. There are a lot of development tools for the third-party applications — there’s just no one-to-one correlation. Initially we’re probably not going to see any third-party products available for it right away, because not only is there a lot more work for us to port it, but it’s going to be a lot of work for third party developers. Some of our products, particularly Grasshopper, is very much a Windowsbased product and it will take quite a bit of time to get that untangled and ported, 22

Bob McNeel, CEO of Robert McNeel & Associates, engages the Shape To Fabrication audience

so that’s not going to be available first release either.

Q: Are there plans to increase Rhino’s 2D drawing output capabilities?

Q: Will it be available in the Apple App Store?

Q: When is it likely to ship?

BM: 2D drafting or drawing is always something that’s on our list of things to upgrade, so you will see some continued improvements there in Version 6, there’s quite a bit of work going on on that front. We’re not particularly paying any attention to any other product in the terms of how it works. Really we’re dealing with the feedback we’re getting from people, what they’re asking for, what their workflows are.

BM: We’re pretty feature complete in terms of what we think we can get done reasonably for version one.

Q: With other vendors increasingly focussing on the cloud, how are you approaching it?

Q: Is Grasshopper 1 going to be a part of Rhino 6?

BM: We watch these things, there’s some interesting things going on there — from my perspective you think about it like porting to another development platform, it’s probably as much if not more work than it was to port to the Mac. It doesn’t seem to be something that people are demanding immediately, I think people have ideas that it’s the solution for problems they have, particularly when working with large data sets or large work groups, and I certainly want to make sure we address those problems over time. If using cloud technology helps that

BM: Correct me if I’m wrong, but if we put something in the App Store we don’t get to provide a SDK or plug-in architecture, so my guess is that we’re not going to distribute it that way.

BM: That’s the idea. One of the things we’re trying to do is to provide a stable development platform for people who are developing for Grasshopper so that there’s not a situation where it’s a ‘moving target’. We’re going to try and get that wrapped up for Version 5 so that there’s a stable version there as well. We’ll move that forward on to 6 as well as Version 6 being the development platform for Grasshopper 2 — some of that work has already started.

www.AECmag.com

then we’ll take advantage of it, but we’re not looking at the cloud or software as a service as a platform that we’re going to port to any time soon.

Shape To Fabrication 2014

Q: Are you considering a neutral file format to help with architects using the variety of different software in projects?

With a focus on cutting-edge technology, innovative construction and applications in architecture, and engineering, the Shape to Fabrication conference attracts professionals pushing the boundaries of design. April’s event was held in Stratford on the doorstep of London’s Olympic Park.

BN: Our strategy has been to leave that up to third-party people with domain expertise in that area. Industry Foundation Classes (IFC) or Building Information Modelling (BIM), or the standard name for BIM I think now is ‘Revit’ I’ve heard… I think there are some people that believe that anyway, the transition from pure geometry into that structured environment with all the additional information that supports that process requires a whole layer of stuff, not just a file format export. There are several third-party products as well as in-house tools that people use to move things down that pathway. It doesn’t seem like anybody has converged on a standard way to do that, there looks like there’s quite a few useful tools out there to do that now. Our focus has been on helping those developers out in any way we can.

Given its location near London’s 2012 Olympics site in Stratford, it was fitting that Shape to Fabrication 2014 included a number of sessions on build requirements for Olympics venues, such as structural challenges at the Olympic Aquatics Centre and design and build requirements of the Arcelor Mittal Orbit. The common theme was the use of Rhino 3D CAD and its offshoot plug-ins, from Metron, which built the Great Britain cycling team bikes, to Speedo’s Team GB swimsuits and aerodynamic swimming goggles.

Q: Have you considered virtual reality? BN: One of the things we’ve tried to do is provide a lot of hooks in the SDK layer and interface layer so for developers all that stuff is pretty open, and I think things like stereo and interface devices are accessible to developers. We’ve experimented with a few [virtual reality devices] but we haven’t really found a use case that makes any sense. The best examples I can come up with are the ‘stereo swim-goggles’ [by Occulus Rift], which are really fun and interesting, until about 20 minutes into it I started throwing up! Q: Have you considered making Rhino’s modelling environment parametric?

In orbit Rhino as a conceptual design tool was integral to Arup’s Arcelor Mittal Orbit. Artist Anish Kapoor’s vision was brought to Arup in three sketches. Rhino was used to focus the project on to one twisting, spiralling design. Arup used Grasshopper within Rhino to control and modify each design stage, such as the angles of the arches and spacing of the visitor staircase. Having adapted the original tubes into a lattice structure based around giant star-shaped nodes, the design was moved into Tekla for manufacture. With the finished structure only metres away from the event venue, those that attended Shape To Fabrication will have left looking at the giant red structure, shaped like a musical ‘bass clef’ in a much more appreciative light. Accommodating processes Continuing the Olympic theme Zaha Hadid lead architect Cristiano Ceccato spoke about the Tokyo 2020 Olympic stadium, which is currently in development. The concept is reminiscent of a grounded alien spaceship. Mr Ceccato called it a “gestural piece that has to be turned into something viable”. Mr Ceccato explained how the initial design had seen countless iterations, which all had to be paired back to account for vast numbers of variables.

His overall message was that, instead of standardising on a single software, architects should follow a process that can be adjusted to accommodate the nature, size and documenting process for all involved. From sport to space Moving away from the Olympic theme, KPF Architects presented its work on Abu Dhabi airport’s Midfield Complex, using a combination of Rhino, Autodesk Revit and Bentley MicroStation. The 700,000m2 building has a 50-metre high ceiling; gargantuan by any standards (and so vast it was covered in two separate talks). “With a project this size, millimetres matter,” KPF associate principle architect Cobus Bothma wryly explained. Mr Bothma set out some cold realities of document management and the perils of working on build projects halfway around the world. He reeled off at length the many challenges regarding file management, clash detection, compatible file formats and design optimisation. The round-the-clock build process, created 100,000 shop drawings to review, and copious Requests For Information (RFI) documents that had to be resolved within the space of five days in order to avoid delaying construction. shapetofabrication.com London 2012’s Arcelor Mittal Orbit

BN: That’s one of those things that seems like, in order to get an interface that makes any sense, you have to focus on a particular discipline. To put a parametric engine behind it you almost have to start thinking about what your user interface is going to be and it starts to turn in a certain direction for some people. As far as back-end tools to support that we’ve looked at things like constraint engines to make sure people can hook those kinds of tools in to Rhino, but beyond that it’s probably not some place we’re going to go anytime soon. ■ rhino3d.com www.AECmag.com

Feature

Into the fold Using robots to bend, shape and fold sheet metal is adding freedom to architectural façade designs. Stephen Holmes visits Robofold and becomes transfixed by robotic origami. Right From its factory in South London, Robofold can produce exciting shapes without the need for tooling Below Zaha Hadid Architects’ Arum sculpture for the Venice Biennale — a six metre high, tulip shaped, self-supporting structure

n the metallic arms of a pair of assembly robots an evolutionary change in architectural cladding is underway. At Robofold’s South London headquarters two 6-axis ABB robots are moving in tandem, gliding into their pre-programmed positions, their suction cups attaching to a sheet of pre-cut aluminium. They arch and twist till the metal is bent and precisely formed into a giant petal, a replica of the one displayed on the screen of the nearby controlling laptop. This process is capable of creating individual cladding panels — something that until now has been too expensive and time consuming. With tools that can now liberate the form of each and every individual panel, architects can transform the overall shape of building façades using Robofold’s design and manufacturing technique.

Robots rock The system works off a plug-in for designs built in Rhino 3D CAD with the software coding developed by Robofold. 24

The designs are translated into folding simulations in the King Kong software. In turn these results are linked to the Godzilla robot software, to simulate robots folding, before the physical folding begins. The folding software can be purchased on its own, but Robofold has also developed 3-axis CAM software, 6-axis CAM software, and other robot inputs to make best use of the hardware it drives. For the construction team, the individual nature of each programmed sheet being formed by robots at the building site means any last minute changes can be quickly and easily rectified. “If you want variation it becomes really valuable,” Gregory Epps, founder of Robofold said. “You can program that in up-front and say what are the parameters that you want to vary. “If you want to tweak the design a little bit you don’t even have to reprogram the CAM software and the robot software — if you had to make a new mould then it would be crazy — so this is super efficient. “You can prototype in production materials and then manufacture using the

same equipment, so you know what you’re going to get.”

Fold over Metal is best for bending, typically using 1.5mm aluminium, cut with the CNC router in the factory. It can also work laser cut steel or stainless steel up to 1.5mm. The steel can be finished with paint or dipped in zinc, while aluminium should be anodised; giving a range of options for finishes. “Normally in architecture we get requests like, ‘can you make it 3mm?’ as they’re used to a flat façade panel,” Mr Epps said. “But once you put the curvature in it and the fold in it you’ve added so much rigidity that you don’t need all that material — you can halve the amount of material that you need.” Accuracy of the panel is defined in the cutting of the flat sheet, and because the process does not stretch the material like a standard press does, holes can be predrilled and trimming is not needed. Local stretch can be calculated as normal with sheet material around the fold, so the www.AECmag.com

designer knows that it is going to fit to the building’s exterior substructure. The speed of the process is slower than that of pressing, but offers labour-saving benefits — it is a single stage process, whereas pressing could involve several stages before being drilled and trimmed by a 5-axis laser-cutter. “Normally you would say that you have to make the forming part to be perfect, but in this case it’s not too critical about the forming, it’s more critical about cutting it right first,” Mr Epps explains. “You can fold something in paper and go and make it — it’s the ultimate goal.” Working with desktop paper printers to verify and tweak sheet designs allows mini versions of an architect’s design to be scaled up for production in metal.

Shaping Venice The largest piece of work to date created by this method was for Zaha Hadid Architects — the Arum sculpture for the Venice Biennale. A six metre high, tulip shaped, selfsupporting structure, the design was crewww.AECmag.com

ated with Robofold’s input and manufacturing service. “We helped the Zaha team to develop their own software so that it would generate all of the data we’d need for production. “They were able to generate valid, folded surfaces, and then out them to us and we would automatically create the production data from it.” The sheets were cut in the UK and transported to the site in Venice where two robots were ready waiting to fold them. Seeing the process in action was a big benefit for the Zaha Hadid team, although this did add pressure. “We still had them on site, changing their mind while we were building it!” Mr Epps explains. This problem only served to highlight the benefits of the process — new parts were swiftly modelled, cut and flown to the site, where the robots folded the new sheets without any mass reprogramming or delays. “I think it was quite daring of them to use us, as this was the largest piece we’d done to date. It’s a really cutting edge tech-

nology, but it shows that they’re a cutting edge practice to be able to embrace it.”

Cutting edge If the future is to grow more dependent on mobile, localised factories then methods of onsite production like these offered by Robofold are destined to lead the way. Once more architects and structural engineers realise that panels formed on site are as accurate as the designer’s 3D model, the increased adoption of this method is inevitable. The next step for Mr Epps and his team is to license the system, supplying two robots, a router, a cutter, a pick-up table, and all the necessary software. Linking with others in the Robofold licensed network, it will become part of a linked FabLab system where each facility can pick up overspill work from others. Such a system of robotic manufacturing methods is an exciting method to free up the future of design from mass produced parts, and add further creative flourish to architecture. ■

The innovative new western concourse single-span roof rises 20 metres, and spans 150 metres to cover 7,500 square metres

The new concourse, which covers 7,500 square metres, and is the largest singlespan structure in Western Europe, could only accommodate supports at a limited number of points, due to various subway and services tunnels. The roof also had to be constructed in a way that did not touch the historical structures. Accurate 3D modelling of the roof and surrounding structures was vital to successful co-ordination between an international team of architects, structural designers and fabricators.

Design verification Because the station is an important historical structure, one of the key challenges for this project was the need for on-going design verification during the extended heritage and conservation negotiations. High-quality, accurate 3D models were vital to the restoration of the historic south facade, and the refurbishment of the vaulted main train shed (including incorporation of photovoltaic arrays). Using detailed survey data along with MicroStation’s power to handle complex infrastructure project data, John McAslan + Partners was able to weave historical structures into a modern project. “We were able to speed up the design process and could accurately predict the outcome www.AECmag.com

tile to assess how they could be best installed — a process that simply could not have been carried out manually.

As the project progressed, John McAslan extended its use of Bentley software from 2D and 3D, to building information modelling (BIM) and GenerativeComponents, without the need to step outside the MicroStation interface. “This is a really smart way to work,” says Mr Accurate 3D modeling of the Green. “We can work in large teams roof and surrounding structures was vital and use 2D, 3D, and BIM to suit the state of the project, the type of project, and the skills of our team.

Autodesk ReCap In 2012 Autodesk launched ReCap, a platform for the growing reality capture market. Since then, the company has expanded its capabilities, added a layer of cloud services and recruited third party developers. by Martyn Day

he manual survey market was revolutionised by the widespread adoption of laser scanners, which can measure millions of 3D points in seconds, building dense point clouds of surfaces. But there remain a number of downsides to the technology. Laser scanners are typically hard to use, expensive and generate huge, unintelligent, process-intensive, files. Autodesk has recognised that the laser scanning software market was ripe for a wider audience, and that it could offer a competitive product and provide tools to enable the conversion of ‘dumb’ scan data to intelligent Building Information Modelling (BIM) models with its ReCap software. At the same time, the laser scanning market has started to see some disruptive technologies, such as the Xbox Kinect, open up new possibilities to potentially lower price points for capturing real-world

data in these point clouds. Typically, laser scanners can cost £40K and upwards and the software to edit and manage the point clouds can cost over £10K a seat. Laser scanner hardware provider Faro has been instrumental in introducing new, low-cost price points (to around £20k) with its small professional scanners. This has increased adoption of laser scanning, and yet to date the software has remained an expensive but necessary add-on.

Autodesk ReCap There are two offerings in Autodesk’s ReCap platform: ReCap Pro, a Windowsbased point cloud registration and manipulation program and ReCap 360, an add-on service that uses capabilities in Autodesk’s cloud to provide a portal for laser-scan or photo captured projects. ReCap Pro is aimed at proving targetless registration of scans in the field and

could run on a laptop or Windows Surface tablet, collating and importing multiple laser scans in real time. While ReCap includes some innovative targetless registration capabilities to assist in alignment of multi-scans, early adopters did wrestle with the accuracy of its results versus traditional target-based registration. In the latest version accuracy can be improved by adding survey points or known distances. Essentially, ReCap Pro enables the processing, cleaning, and visualisation of large data sets on the desktop from laser scans. It is hardware independent and supports the import of over 20 industry proprietary, text-based and open formats. The software has a modern, easy to use interface and provides a suite of tools to clean up, edit and organise laser scans. The data alignment between scans can be done by electing the same objects in

Next generation scanners New low-cost scanners are typically hand held. They provide low resolution scans, and are therefore perhaps best used for interiors or individual objects. 3D Systems Sense’s 3D scanner costs just $399. It is aimed at non-professionals capturing small objects in 3D using the same technology as Microsoft’s Kinect. 3D Systems software optimises its output for its 3D printers. . ■ cubify.com/en/Products/Sense

dotproduct offers a sub$5,000 hand held scanner, the DPI-7, which consists of a cradle / handle and an Android 7” standard tablet. The Phi-3D software uses an indoor positioning system to build a 3D map from the scanner. Once enough points have been gathered to create a map, the screen turns green. Intel recently invested a large sum in the firm. ■ dotproduct3d.com

Zebedee’s ZEB1 is an unusual looking handheld scanner with a spring mounted sensor.

the scene from different scans. The software uses powerful algorithms to provide registration between the scans. Data points from surveys can also be incorporated into the model. These provide additional accuracy to ReCap Pro’s registration capabilities. As most scanners incorporate photo images with point cloud data, ReCap can be used to produce 3D interactive or single point panoramic visualisations.

ReCap 360 With firms doing more and more laser scanning and with point clouds generating huge files, local storage is not always an option. ReCap 360 provides additional storage space that can be expanded as needed. Edited point clouds can be viewed and shared via a web browser, where they can be annotated without destroying the original file. ReCap 360 comes with 25GB of Autodesk 360 storage and 50 cloud credits for ReCap 360 projects, which can be used to cut processing time. From the cloud Autodesk manipulates the data remotely and streams the video to local browsers. This takes the processing weight off local machines, but is as interactive as if it were running locally, giving maximum image resolution even on huge multi-scans, which could be terabytes in size. ReCap 360 offers additional tools such as bounding boxes for easier editing of big point clouds. Once cleaned up, highdensity, mesh models can be created to provide a suite of mesh tools and options to create a meshed model that suits a target application or system. Again this all happens interactively through the browser in real-time. Under the banner of 123D Catch, Autodesk previously released a product and web service that could take multiple photographs or a Go Pro capture from a aerial drone of an object or a scene and turn these into a textured, meshed 3D model. A high-resolution version of this is built into ReCap 360, enabling photos to be uploaded and textured models produced at the press of a button. There is a suite of tools for manually stitching photos together prior to the meshed model being generated. Survey data can be added to improve the accuracy of the final model.

Memento Autodesk is currently running a Labs project called Project Memento, which is the company’s innovative meshing technology. Memento is planned to be a all-in-one www.AECmag.com

solution, taking in data from any reality input capture devices (photo, scans, structured and unstructured), to produce high quality mesh models which can be used for digital workflows. Autodesk has recently done work for the Smithsonian group of museums and research centres in the US, capturing artifacts, as well as for a Swedish museum using MRI scans of an ancient Egyptian mummy. The results of this can be delivered through the web or mobile, or possibly used in Autodesk applications like Maya, Mudbox or even 3D printed out.

According to Autodesk, more than ten companies, serving markets ranging from medical and civil engineering, to video games and Unmanned Aerial Vehicles (UAVs), have started developing specific applications that make use of this capability, or have started integrating this capability into their existing applications

Third party

ReCap has a great interface and is one of the most innovative desktop / cloud service product that Autodesk offers. In the 1980s AutoCAD beat competitors by offering 80% of CAD system functionality at 20% of the price. It is doing something similar with ReCap. Plus. there is also a healthy amount of disruptive new technology in the market to make users think differently about how they design and model. The reality is that 3D modelling is time consuming and software providers need to find ways to limit that by modelling in context, or automating the creation of an as-built model. As a result, Autodesk sees point clouds being much more of a commonly used data format. However, the price of the scanning hardware still needs to come down considerably.

One of Autodesk’s tried and tested routes to adoption is through third party developers who enhance the capabilities of Autodesk’s platforms by adding specialised add-ons. With ReCap Autodesk is following that path and is actively recruiting to build on its platform with a ReCap Connect Partnership Program. For now there is a small core and, as one would expect, those competitors with a lot of revenue to lose are not involved. But as ReCap usage grows the days of expensive registration software are numbered. Third parties can either write their own import plug-in to import data into ReCap using the Capture Codec Kit (CCK) that is available as part of the new ReCap desktop version, or join the Embedded ReCap OEM programme to export from point cloud processing software directly into

Case study Will Norton, structural engineer at McElroy consulting engineers and project managers, explains how Structural BIM has revolutionised the way McElroy undertakes design projects.

Structural BIM model designed in Revit

Structural BIM L

ike many small to medium enterprises (SMEs), McElroy recognised that Building Information Modelling (BIM) could offer a host of benefits but had yet to investigate it fully due to resource constraints. Acknowledging that BIM was fast becoming the norm and with a desire to capitalise on its proven benefits, structural engineer Will Norton spearheaded McElroy’s first ever BIM project using Fastrak, CSC’s steel building design software, and Autodesk Revit. By employing what is often known as ‘Structural BIM’ or ‘Internal BIM’, McElroy started by sharing project data within its own structural design office, communicating data between the engineer’s code-compliant design model in Fastrak, with the technician’s Autodesk Revit model. McElroy’s primary objective was to understand and benefit internally from Structural BIM before later adopting ‘External BIM’, which would enable external data communication upstream and downstream with the client, architect and contractor.

McElroy’s first project McElroy’s first Structural BIM project was an extension to an existing building with relatively simple geometry. It was specifically chosen so the team could fully learn the workflows that are essential for effective BIM synchronisation; to build confidence before implementing BIM workflows on larger and more complex projects, and for External BIM at a later date. The project required a 1,300m2 extension to be added to an operational building owned by Teva Pharmaceuticals Group, www.AECmag.com

p33_AEC_MAYJUNE14_structuralBIM.indd 33

consisting of a 17m high steel braced frame weighing 175 tonnes. Using Integrator, a free plug-in from CSC that enables either full or part models to be synchronised between Fastrak and Autodesk Revit, McElroy started by importing the general arrangement model from Autodesk Revit to Fastrak. As the design progressed, there were inevitable changes to both the set out and design philosophy and McElroy had to assess the viability of various design options and locations, for example masonry walls compared with concrete lift cores. The materials and locations were amended in Autodesk Revit and then synchronised with Fastrak, whereby McElroy’s structural engineer could investigate the effects on the structure. The changes in Fastrak were then synchronised back to Autodesk Revit; a true round-tripping which was performed numerous times on this project. “Integrator gave complete control when synchronising models,” Mr Norton said. “We could choose whether to include or exclude different member groups and geometry settings and it provided logical colourcoding so we could visualise the design changes. It was abundantly clear as to which members were new, modified or deleted. “The position of various elements, such as lift cores and mezzanines, within a proposed building envelope can frequently change at scheme design stage and the Teva extension was no exception,” explained Mr Norton. “Without Structural BIM integration we would have had to remodel the structure twice for each design change, once in Fastrak and again in Autodesk Revit. With seamless synchroni-

sation between the two software packages we were able maintain a single model, sharing all the latest data. The implementation of Structural BIM has streamlined our design approach, reduced the risk of errors, provided huge time saving and improved communication enormously.”

The future of BIM for McElroy Having been rewarded with such success early during the Teva project, McElroy is now utilising Structural BIM on two larger steel frame projects alongside the Teva Project. The first is a 210 tonne upgrade to an existing facility and the second is a larger scale newbuild pharmaceutical facility weighing in at 1,750 tonnes. Structural BIM has now been adopted for all medium and large sized projects at McElroy. “Clients are increasingly expecting 3D visualisations at the consultation stages of projects,” Mr Norton commented. “We now produce 3D models that help to communicate our designs effectively, an integral aspect of what Structural BIM can offer.” Due to the time saved modelling, McElroy has seen projects become more profitable and engineers have been able to cost design schemes more accurately due to the more efficient working methods afforded by Structural BIM workflows. “The future is BIM, whether it be Structural BIM or External BIM,” Mr Norton said. It has made McElroy more competitive, increased productivity and enabled us to deliver a better service. Those who adopt BIM place themselves at a distinct advantage in the market. ■
