INDUSTRY focus Constructability DBM Vircon uses its design engineering experts and the latest technology to transform standard structural designer's production models into fully connected LOD 400 models. David Chadwick reports The most common refrain in the construction industry, whether you are involved in a major infrastructure project or a small-scale housing development, is to get your planning done early and to involve all stakeholders in the process. A simple statement of the obvious, but the ability to explore all aspects of a project and identify potential issues early on and then take steps to mitigate or eliminate their effect pays massive dividends in the long run, and improves the ability to keep projects on schedule and within budget. Whilst it may be a basic truism in planning, for many reasons contractors often pay lip service to the principle and go for the most cost-effective or cheapest options - and generally suffer the consequences. In fact, as DBM Vircon suggest, early connected models can result in more accurate and detailed designs for bidding, can tighten and reduce bids by up to 5% to 10%, and can reduce costs of steel by up to 10% due to accurate procurement and reduced waste. The cost savings may even continue after contracts are awarded, as projects move forward and RFIs and other expensive interruptions to the schedule are eliminated. I spoke to Andrew Bellerby of DBM Vircon about the importance of effective pre-planning on both major infrastructure projects and commercial developments, the problems that arise from inadequate planning, and how his company's expertise has been used to eradicate them. A global construction company headquartered in Australia, DBM Vircon provides professional expertise and guidance on using the latest technological advances in digital engineering to assist clients and contractors through all stages of a project, from concept design to completion and operation. The company supplements its technical expertise with visualisations, virtual and augmented reality tools, and asset model maintenance to facilitate a client's involvement in the process, clarify complex details and to enhance the creative aspects. Pre-construction planning is just one element among several digital engineering modules which the company offers. It addresses the common problem that Design-Bid-Build projects come up against, based, as they are, on 'value engineering', which is described as 'a systematic, organised approach to providing necessary functions in a project at the lowest cost, promoting the substitution of materials and methods with less expensive alternatives, without sacrificing functionality'. With tight budgets and cash shortages, the rising cost of materials and shortage of experienced labour, the natural inclination of companies is to pare costs and resource requirements to a minimum. The obvious corollary to that is that essential elements of the project are overlooked. WILL IT WORK? The most obvious of these, Andrew suggested, is 'constructability'. Is the structure capable of being fabricated and erected as the architect and the structural designer envisage? Pre-construction planning allows stakeholders to focus on design development, using DBM Vircon's integrated design-detailing to ensure that the proposed structure, or steelworks, can be easily fabricated and erected with as little wasted material as possible. The pre-planning process enables project managers to pinpoint the small details that are frequently overlooked during standard planning meetings, such as the clearances required to install 30 September/October 2023

INDUSTRYfocus equipment, handle tools and set up welding operations, and even the need for temporary structures to facilitate construction or the use of hired equipment. If not addressed early, any of these may prove to be costly, or impossible, to rectify during actual construction. Assessing the constructability of steelwork during the design process is not always possible, though, either through time constraints or lack of technical knowledge on the behalf of the structural detailer. It is for this reason that DBM Vircon has been brought in on many large and complex projects to provide construction insights that contractors and designers are themselves unable to provide. Their Design Assist service is designed to give all project stakeholders a clear and unified understanding of the design intent, and to modify early-stage designs to achieve optimal results. The Level of Detail (LOD) required for this is beyond the LOD 3 (or LOD 200 using US AIA definition) typically provided by the structural designer's engineering models, providing positions, sizes, orientations etc of steelwork which may be developed to around 80% completeness. Collaboration with DBM Vircon allows their experienced engineering team to progress the design further, aiming for a full LOD 5 (or LOD 400) connected model which includes additional information to fulfil the tasks outlined above, but also to incorporate ancillary data and further functions like building schedules and costs for 4D and 5D simulations, lock in and keep track of material prices and suppliers, and expedite procurement. DIGITAL ENGINEERING With a comprehensive amount of information available, DBM Vircon can leverage the data to provide a full digital engineering solution - a Design-Build- Manage lifecycle which takes the initial concept design through to facilities management. The whole process is supported using digital project management including 4D and 5D simulations, digital twins which serve to provide Serviced Asset Information Management (SAIM), 3D Visualisations and Virtual and Augmented Reality. They can even set up animations to build complex models using CG from the ground up, and gamification tools and visuals to explore designs in a gaming environment, either for training or education purposes. Digital Project Management is a practical solution based on DBM Vircon's agnostic software and centralised data-mapping. It allows the entire project team to collaborate, breaking down data silos and enhancing decision making. The 3D modelling and structural design applications that the company focuses on are familiar to all, and include Tekla, Prosteel, Revit, Plant 3D and Navisworks. The company's expertise, developed as creators and curators of foundational datasets and years of experience gained through supporting clients on multibillion-dollar projects from specification and procurement, forms the basis of its Digital Engineering Advisory. This has helped the company deliver projects for clients and transform their AEC or asset information management processes. It has also enabled the DBM Vircon Digital Engineering team to integrate design data and associated information from multiple systems and context data from virtual and augmented reality solutions to create digital twin platforms. DBM VIRCON DBM Vircon is a truly global enterprise, with offices in Australia, the United States, Canada, India, the Philippines and Oxford in the UK, where Andrew Bellerby is based. As a global company, most of the projects that the company is involved use the company's experts wherever they are based and whenever they are required, allowing for a 24 hour working output. Although Steelworks have been used as a principal example here, the company has a wealth of experience in reinforced concrete, bridges and industrial design, the energy market, transportation, healthcare and cultural, commercial and residential projects. www.dbmvircon.com September/October 2023 31
