Benefits of BIM Copy

So there are loads of reasons why, but if I had to pick the ones I think most importantly it would be these. I won’t explain all of these, but just covering the top 3:

• To make a decision, you need the right information: Whether it’s to buy something, to choose one design over another, to hire more people, whatever it is – you need the information at the right time. This is at the heart of BIM, identifying what information is needed, by who and when.

• Consistency: you will work with many different partners and suppliers, but you are all working toward the same goals. To achieve them in the most productive and efficient ways, we need to be following the same standards, methods and procedures so that what we do is compatible.

• Collaboration is at the heart of it all: by getting consistent process and using the right tools and technology, we can collaborate much more effectively and be in sync with each other throughout a project. More time can be spent delivering the job than trying to communicate.
Case studies are a good way of demonstrating the real-world value of BIM implementation by using clearly defined metrics to measure key performance indicators.

Case Study 1: 100 Binney Street, Massachusetts.

10-storey office building built-in 2007.
Value of coordination and clash detection.
Case Study 2: Leeds Arena, UK, as per below:

• £60million multi-purpose arena built-in 2013.
Case Study 3: Sydney Opera House

Multi-venue performing arts centre at Sydney Harbour.

BIM Academy supported a major project to provide specialist facilities management (FM) technical capability for Sydney Opera House.
Case Study 4: MTR Corporation:

Mass Transit Rail Corporation (MTR) is regarded as one of the world’s leading railway operations, carrying on average 3.6 million passengers per day.

There was the development of the project which investigated the feasibility and business case for collating and linking asset data from various 3D digital and 2D conventional formats derived from ongoing rail infrastructure projects and migrating this data to a new asset and facilities management systems.
2D BIM is a digital geometric model that constitutes an X and a Y-axis associated with further information. Early CAD systems were 2D models, where plans and sections could be developed on computers more quickly and more accurately than manually, on a drawing board.
More advanced modelling tools now allow parameters, constraints and concepts to be attached to the 2D model. However, most in the industry would not consider 2D geometry models as BIM.

3D BIM is a digital geometric model that constitutes an X, Y and Z axis associated with further information. 3D modelling tools have been a huge success because:
•2D views of geometric information can be generated from the 3D model at different levels of detail.
•Schedules can be generated, reporting on objects of different types within the 3D model. 
•Multiple 3D models can be combined to report on any geometric clashes.

All of these features greatly improve accuracy and efficiency and reduce the risk of errors occurring on projects.

4D BIM is adding scheduling information to model construction sequences. Adding a dimension of time allows the project team to better visualize how the construction will be sequenced. From a contractor point of view, this is vital. 4D BIM was a huge step forward for the industry when first made possible through the use of new modelling tools – it demonstrated collaboration between the design and construction team through coordination and sharing of 3D models.

5D BIM is generally considered to be adding cost information to a model. When discussing 5D BIM, it is advised to clearly set out these specific requirements. For example, is the team expected to be providing capital or operational costs? Are these costs expected to be pre-tender estimates or a record of as-built costs? Who is responsible for adding this information? What method of measurement is to be used?

6D BIM is considered by some to be adding facility management to the information set. However, there is little industry consensus on this, and arguably this isn’t a ‘dimension’ at all. If discussing 6D BIM, it is strongly advised to set out precisely what is required so that all parties have a clear understanding.

7D BIM is considered by some to be adding sustainability information to the information set. As with 6D BIM, be sure to carefully define the specific information required in terms of data types, scope, units, rules of measure, etc.

8D BIM is considered by some to be adding health and safety information to the information set. As with 6D BIM, be sure to carefully define the specific information required in terms of data types, scope, units, rules of measure, etc.
Relevant stages and information exchanges.
Perhaps no BIM presentation is complete without an image of the UK maturity model (pictured above), developed by Mark Bew and Mervyn Richards. Instantly recognisable by its wedge shape, it has been a useful diagram for the supply chain to identify what it is to deliver and the competencies required while the client can understand what the supply chain is offering. In essence, it is all about communicating expectations.

For anyone new to BIM it can be easy to get your 2D, 3D, 4D and 5Ds mixed up with your BIM Levels 0, 1, 2 and 3. By defining levels of maturity, organisations can set a benchmark as to where they currently are.
The suite of ISO 19650 documents.

The suite consists of four published standards and one further standard which is in development (expected publication 2022).

The core focus of each standard:

Part 1 of the ISO 19650 suite presents some revised concepts and principles behind BIM implementation. These are based on best practice and have been presented in a clearer, less intimidating way than previous BIM standards. They illustrate not only BIM concepts and practices but also lay out the value of BIM implementation from a business standpoint.

Part 2 of the ISO 19650 suite concerns the delivery phase of built assets. On the Client’s side, it presents a framework that allows the Client to establish their informational requirements in a holistic and comprehensive way. On the Supplier’s side, it prescribes an ideal environment for the collaborative production of asset information which takes place as a direct response to the Client’s informational requirements. Ultimately, it ensures not only that the Client fully articulates their needs, but also that the Suppliers can produce and deliver this information in a way that is most efficient and effective, adding considerable value to the Project.

Part 3 of the ISO 19650 suite concerns the operational phase of built assets. Like Part 2, it presents a framework that allows the Client to establish their informational requirements in a holistic and comprehensive way, however, the focus here is on the information that the Client requires for the efficient and effective operation of the asset following handover.

Part 5 of the ISO 19650 suite concerns security-related issues associated with the digitalised management of information. This seeks to make all involved parties aware of the vulnerability of the information that is (or has been) produced and prescribes a number of solutions for the management of security-related risk.
This illustrates the various initiatives which are being used to roll out BIM globally.

More than 30 countries have adopted or are planning to adopt BIM.

Various methods are being used to adopt BIM around the world, with a focus on the use of governmental mandates.
