The document summarizes a presentation on MEP in BIM. The presentation agenda includes an introduction to BIM, platforms and interoperability, current and future legislation, and a conclusion. The introduction defines BIM and its uses, including coordination, clash detection, and facility management. It also discusses the paradigm shift in moving from 2D CAD to a collaborative 3D model. Platforms and interoperability explains how different software platforms interface and exchange data. Current legislation mandating BIM is discussed for the UAE, UK, and globally. Standards and guidelines for BIM implementation are also reviewed. The conclusion discusses new roles and responsibilities with BIM and addresses common misconceptions about BIM adoption.

As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its lifecycle from inception onward. National Institute of Building Sciences a process involving the generation and management of digital representations of physical and functional characteristics of places.

- 25. 25 Heriott Watt University 17th Nov 2015 Dubai/UAE 3 - Legislation Current and future Dubai Municipality's 2013 mandate – circular (196) – pertained to the application of "the first stage of BIM in the construction and mechanical (parts) on buildings and the following facilities: 1.Buildings that are above 40 floors. 2.Building with area’s larger than 300 thousand square feet. 3.Specialized buildings such as hospitals, universities, and all that is similar to that. 4.All buildings requested on behalf of a foreign office." As the latest circular (207) continues, it is for those reasons, and the other benefits provided by BIM, that "it has been decided to expand the usage of it (the technology) to include the following: First – Architectural and mechanical works for the following buildings: 1.buildings that are above 20 floors. 2.buildings and facilities and compounds with areas larger than 200 thousand square foot. 3.buildings and special facilities like hospitals and universities and all that is similar to that. 4.all governmental Projects with BIM requirements. 5.all buildings and Projects with BIM requirements that are requested from a foreign office." The circular continues, adding the requirements of its previous circular, would continue to stay in effect: "Second – For buildings and Projects with BIM requirements that were mentioned in the previous circular announcement, which is number (196) in year 2013(already mentioned above and they are): 1.Buildings that are above 40 floors. 2.Building with area’s larger than 300 thousand square feet. 3.Specialized buildings such as hospitals, universities, and all that is similar to that. 4.All buildings requested on behalf of a foreign office. And this is starting from 1/6/2015 (1 June, 2015), and that the consulting and advisory offices are legally questionable and responsible on applying this.“
- 26. 26 Heriott Watt University 17th Nov 2015 UK – 2016 Target 3 - Legislation Current and future Level 0 BIM In its simplest form, level 0 effectively means no collaboration. 2D CAD drafting only is utilised (source: NBS National BIM Report 2014). Level 1 BIM This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information. CAD standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE Level 2 BIM This is distinguished by collaborative working – all parties use their own 3D CAD models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level. Level 3 BIM Currently seen as the holy grail, this represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralized repository.

- 32. 32 Heriott Watt University 17th Nov 2015 New Roles and Responsibilities 5 - Conclusion 3.1.1.1 BIM Manager (Strategic) It is important to understand how vital a BIM Manager’s role is. It is not simply a rebranded CAD Manager, nor does it replace the CAD Manager’s role. It is about understanding what BIM can achieve: vision, engaging external stakeholders, collaborating partners and the internal teams. Somebody credible has to be responsible for the BIM strategy, the process change and the cultural impact. In house or outsourced, successful models cannot be built without a strategic manager. Business and project size will dictate the structure of the BIM team. The BIM Manager could perform all functions on smaller projects. No matter how large the project you only need one person responsible for the strategic function. 3.1.2.1 Coordinator (Management) The management function is project- and BIM- specific. Each project needs a Coordinator to help set up the project, audit the model and co-ordinate with all collaborators. Multi-disciplinary co- ordination with BIM is essential. A Coordinator may manage several small projects. AEC(UK) BIM Protocol
- 33. 33 Heriott Watt University 17th Nov 2015 Reflections and Misconceptions 5 - Conclusion • BIM is a process• BIM is a software • It is replacement for CAD • It is for design only • There is a magic button • It is additional cost to the project • It is hard to learn • It is just another buzzword. • CAD represents a part of it • It covers the full project life cycle • Same amount of work, less risks • Same cost, increased ROI • The change of mind set is harder • It is being implemented by governments
