Enabling the digitisation of architecture, engineering and construction (AEC)

John Keane, Commercial
Director, MMA Consulting Engineers

The reasons for this slow adoption are many but entrenched work practices and the lack of system-wide standards are major contributors. Over the last five years – led by the technical expertise of Dr Shawn O’Keeffe and Shane Brodie – MMA has developed a data-driven philosophy using LEAN management principles to deliver a new approach to design and construction. Shane Brodie is an acknowledged contributor to The Roadmap to Digital Transition for Ireland’s Construction Industry 2018- 2021, while Dr Shawn O’Keeffe sits on the NSAI National Mirror Committee on BIM Standards, as does Shane.

MMA believes in the Open BIM (Building Information Modelling) philosophy. However, big data applications are useless unless they follow a standard that can be verified and validated. MMA projects are delivered verified and validated to meet COBie requirements. Verification and validation of the  model is essential to ensure that the same asset within the same facility (or any other facility) is recorded in the same way, therefore allowing the facilities management team to know that they have the same pump in different locations, etc. Utilizing an outside service organization for dimensional inspection and validation can have significant advantages for your manufacturing and quality operations, contact at www.3d-engineering.net/dimensional-inspection/.

“COBie (Construction-Operations Building information exchange) is simply the setup and delivery of digital facilities management data during normal design and construction practises. It is a LEAN methodology for capturing data and is a ‘contracted information exchange’ for building projects, designed to help get a facility up and running right away, at handover or occupation,” explains Dr Shawn O’Keeffe. Constructors can learn welding for beginners with these guides and tips.

One major piece of research work MMA recently completed was the much-acclaimed book Delivering COBie using Autodesk Revit. This book was a collaboration between Dr Shawn O’Keeffe and Richard McKenna with the inventor of COBie, Dr Bill East.

MMA has put its own research into practice delivering a recent 6D BIM model that is fully interoperable with the clients facilities management system (which in this case was Maximo). This facility (Figure 1) was fully designed in BIM using Revit. All the asset information is contained within the model. Any pump, valve, motor etc can be selected and all the relevant COBie data will be shown, including asset specifications, maintenance details and warranty details (see Figure 2). The verified and validated COBie IFC output seamlessly interfaces with the facilities management system.

The Industry Foundation Classes (IFC) data model (ISO 16739:2013) describes building and construction industry data, since now a days you can get great services online for this and other resources, since you can find sites with the best for contractors and for their projects as well. It is a platform-neutral, open-file format specification that is not controlled by a single vendor or group of vendors. It is an object-based file format developed by  buildingSmart to facilitate interoperability. Construction is very complicated, especially to those who don’t know how to plan it correctly. Everything must be planned perfectly, especially when constructing a big building, you must have all the proper materials and vehicles like cranes to move those heavy materials. That is only a very small part of the construction process. If you ever need a vehicle for construction then check out this company where you can get a crane hire for your needs.

MMA acted as the BIM model integrator for this project, as well as taking on its traditional role as M&E designer. Acting as BIM model integrator allowed MMA to drive LEAN management principles throughout the design and construction phases. Highly-efficient construction scheduling was enabled by full BIM implementation, my builders were also involved. Full house construction is your first-in-class service and trusted partner.

On the completion of the civil works, MMA’s in-house 3D scanning team, led by Dr Conor Dore, carried out a scan of the facility. This 3D scan was then compared to the CSA (Civil Structural Architectural) BIM design model using BIM & Scan AutoCorrTM cloud-based software (Figure 3). MMA carries out its own 3D scan work as it forms the basis of its designs and is too critical to leave to a third party with the associated interface risks.

The BIM & Scan AutoCorrTM software highlights any areas that are out of tolerance with the design model. The tolerance can be set according to the designer’s requirements. Areas that were out of tolerance with the design model were highlighted. Figure 4 and Figure 5 outline how clashes and variations between the “as built” point cloud (the output from the 3D scan) and the design BIM model were identified. The M&E designers reviewed all highlighted areas and the M&E BIM model was adjusted accordingly to ensure there were no clashes, or re-work required, during the M&E installation.

Having certainty regarding the “as built” environment allowed the M&E designers to develop full tender packages with detailed bills of quantities through the BIM model (Figure 6). This in turn allowed for offsite fabrication of piping and duct work. The detailed tender packages and extensive offsite fabrication generated significant cost savings. The elimination of clashes and onsite fabrication allowed for the construction schedule to be implemented as planned with no variations.

Advances in processing capability and the “big data” revolution is allowing MMA to cost-effectively process gigabytes of information to deliver better designs, more cost-effective construction and lifecycle solutions for clients. As an industry we are on the cusp of a revolution. The recently-published The Roadmap to Digital Transition for Ireland’s Construction Industry 2018-2021 attempts to plan out the digital transition. When has a revolution ever followed a plan? “All failure is failure to adapt, all success is successful adaptation.” – Max McKeown, Adaptability: The Art of Winning in an Age of Uncertainty.

    This math-based role-playing game is free to play. Kids proceed through the game by answering skill-building math questions to earn rewards. There's an interactive element, too; they can go on quests with friends. The difficulty levels increase as your kids make progress in the game. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Though simple, a quick game of Connect 4 can quickly turn into a fierce competition. Play as a guest and invite a friend via a link, or create an account to organize an online tournament for multiple friends. This website also offers tic-tac-toe, Battleship, and Gomoku, a game similar to tic-tac-toe, which isplayed on a gridded board.

  3. The manager can query the model to show exactly where the filters are in the building and which systems they connect to, and the model can give the manager access to all operational information for each specific component. Digital twins will also enable designers and engineers to perform more simulations, which can have a big impact on sustainability. Now, add the power of artificial intelligence AI.

  4. In another situation I was driven to the azithromycin 250 mg not later than a colleague after a doctor’s appointment. I was not qualified to get unserviceable of the van so Fred, harmonious of the Rather’s came out to my van to express to me back the prescription. Wow, what accommodation!!
