My presentation will be divided in three parts: -the first will be about why a BIM has been outlined by the government and why 2016 is a crucial year for BIM --in the second part I will explain what the EIR is and why is the most important document for a BIM implementation -the last part will discuss 5 typical working issues that might be mitigated by using BIM
I’d like to start with a question about what BIM is for you, so
Raise your hand if you think that BIM is An authoring software to create a multidisciplinary 3D model…
Raise your hand if you think that BIM is A linear process defined by a series of tasks that should be followed
Raise your hand if you think that BIM it’s something else… I will give you the BIM definition at the end of the presentation
2016 is a crucial year for BIM for 3 deadlines. The first has already passed and it is (as many of you might know), on April 4th, centrally procured public sector projects will require the implementation of BIM LEvel2.In addition ”All centrally funded government will be required to provide a clear and complete (EIR) with all contracts”.I hope you have seen a real change in your organization process.
The second is 3 October 2016, all centrally funded departments will need to have “the capability to electronically validate BIM information delivered from the supply chain” and “making progressively more use of theirs data for key business activities”
The last one should be November 2016 and a new version of DPoW will be delivered.
April 4th deadline has been set up by the Government Construction Strategy released in 2011 which stated that the Government will require a fully collaborative 3D BIM (with all project and asset information, documentation and data being electronic) as a minimum by 2016. The GCS is also trying to reach two main goals: the first one is reaching 20% reduction in the capital cost of buildings and the second is the 33% cost reduction in in the initial cost of construction and the whole life cost of built assets
It means that BIM aim is to make O&M more efficient because today it costs 10 times much than it should. How can we do that with BIM?We should adopt another approach that is the early engagement of the end user, find out what they want and deliver it.That’s why one of the BIM fundamental is “Start with the end in mind”
How can we do that? With the EIR that is the document that must be produced by employers for all the centrally procured government projects.
The EIR is the document that have been defined by the PAS 1192-2 and it must contain all the requirements that should be considered before starting any project.All the requirements are divided in 3 main groups: Technical…., Management…. and Commercial….To underline how crucial the EIR is, I will focus the attention on 5 different requirements that should be investigated during the EIR production that are: software platforms, LOD, Training, Standard and BIM deliverables. I’ve chosen only 5 requirements because of timing. I’m going to explain why these 5 aspects will be extremely beneficial for the whole process from the concept to O&M stages.
Why a series of software platforms should be set up and defined in advance? How several tools can affect the project efficiency?
The main reason is related to interoperability because all project data should be accessible and reusable at any project stage (if all the software platforms will be correctly identified since the very beginning, interoperability shouldn’t be an issue). BIM is all about data that can be consumed and used as much as necessary.
All the data that can be extracted by a 3D model must be reliable and validated. Depending on their need, a stakeholder might export data in different formats, such as COBie, PDF, XLS…All the stakeholders should also have the access to different types of data (e.g.: data that might be fundamental for a structural engineer could be irrelevant for a Cost estimator, but both of them must access to the right data that must be validated and be as a consequence, reliable.)
Another EIR section is about the LOD applied to both general and components level.
All the data should be collected and structured for reuse (as built) throughout an asset's lifecycle in order to deliver a broad range of support services from the design, construction to the operational phases. Define the LOD of an item will also help other stakeholders to improve and define the cost benchmarking: at the same time the data quality and the communication between the different professionals involved in the project will be consistently improved
Define the LOD at earlier stage will also help designers during the iteration and revision phases (e.g. when the LOD 500 will be reached, the data value will increase its relevance and should also facilitate the collaboration with manufacturers and the supply chain).
The first requirement is about training
A series of training will be required during all the project stages in order to share the right knowledge and the right information at the right time to the right people. This approach can be considered as future oriented for all the stakeholder because methods, skills and procedures can be reused for other projects.Skills improvement will be fundamental to develop new internal methods and procedures both for companies and contractors…Future training will be developed thanks to the lessons learned
The more the training will be exhaustive the better, because the same skills could be used for other projects, the group skills will be strengthen and the company added value will increase.A series of ah hoc training should also be provided and should be customised for those that are entering in the industry and for those who are already in it.The prospective and the approach to BIM will be of course completely different.
In the last years, a series of standards, methods and procedures have been developed by the government and other authorities
All these standards should be implemented in order to create a BIM framework.
There are a series of standards developed by the government, such as BS1192 for CAD standards, PAS2 for CAPEX, PAS 3 for OPEX, PAS 4 for COBie, PAS 5 for Security, PAS91 for construction, GSL for O&M, BS8541 for libraries, and BS7000-1,2,3,4 for management systems
There are also other documents such as ISO 90000 for asset management, the RIBA Plan of work, Uniclass for classification for naming convention, the CIC protocol, NBS toolkit and the NRM defined by RICS.
In the EIR, depending on the project and on the client’s requirements, all these document should be implemented and aligned in order to develop an efficient and complete BIM process…in the future it should be considered as bim level 3.
Series of new BIM deliverables that can be provided during the handover and the O&M phases such as:…. I will focus the attention on the most important and new document that is the AIM defined by PAS part 3
AIM can be provided for a single asset, systems and entire asset portfolio.The AIM contains graphical info, non graphical info, documentation…metadata.All these information are coming from published part of the CDE and Data can be extracted and updated.
As a result every BIM object will be a 3D cell with graphical information, it will contain a series of attributes, labels documents such as instructions, warranties…and also 2D documents.
How BIM can improve or solve common difficulties that every professional involved in a project have faced at least once during a project. Let’s see how BIM can mitigate the most common problems during a project
One of the most common problem is understand what the client is expecting in order to reach his goals. This is the reason why it might happen that some goals or objectives haven’t been set up clearly since the beginning This causes miscommunication, wrong requirements definition and, as a final result, wrong output/delivery
How BIM can mitigate or partially solve this problem? PLQPLQ are a series of preliminary questions that should be answered by the client at each of the 8 RIBA stages. The PLQ might be used as a test for each RIBA stage to check if the right requirements has been correctly set up and understood (if the client, the contractor…are at the same page).Typical PLQ for the Strategy definition are: What is the IM strategy? What are the portfolio’s technical strategies? Have the stakeholders need been captured? And so on…
Another problem might came out when people that take part to the project are not involved at the right time.This will cause miscommunication between client and contractor and it as result it will cause an output completely different from client’s expectation.
A possible solution can be found in 3 different document :PRE BEP, EIR and Post BEP. These documents will define all the client’s requirement together with roles and responsibilities that should set up a virtuous and collaborative process.The Post BEP will also specify how to reach and solve a specific task/goal.
Another issue is about file formats. Not every file format can be used or reused for different purposes.It might happen that some file format can’t be read by other software, data can’t be properly extracted…worst scenario is data loss.As a consequence, it means that data can’t be properly validated, extracted and furthermore consumed as it supposed to be.
How to avoid that? EIR and Pre BEP. To improve the quality of data/information, all the software and file format should be stated since the very beginning in order to reduce risk. Define this requirement will add a priceless value to data, it will increase the quality of data and will make them reusable.Define all the software that will be used during the process should also avoid interoperability issues.
Other problems are related to people and tasks management, for example when the right person has been involved too late in the process.This can cause a late deliver of the work with the risk of exceeding as far as time and, even worse, budget.
To avoid that, PAS 2 CPI should be used to identify and define how to deliver client's requirements on time and at the right cost, such as the Role and responsibility matrix. Implemented by companies
One last technical issue is about where the information are stored. Sometimes we don’t remember where that particular was stored or who was responsible for a specific document.It’s even worse when a colleague is replaced by another one? Where and how did he/she stored the file?All these problem, as a consequence, can generate time waste and in a long term may cause coordination and validation issues.
How can this problem be solved? CDEThe CDE is “a single source of information for any given project, used to collect, ,manage all relevant approved project documents for multi-disciplinary teams in a managed process”. It means that CDE is a centralised management entity that can be used as a database that will help to save time and reduce errors and risks.
So…to summarise everything….what is BIM?BIM is a process that involves people, technology and other processes by which digital information are used to manage the building process and subsequent operational and maintenance aspects. This is the BIM definition for the APM (BIM task group)
