BIM is first of all a method and a tool, but is also an input to start a new phase of industrialization.
Construction process is not very industrialized, therefore small projects don’t allow to use a big strategy.
There are a lot of new technologies today, but maybe we don’t have the knowledge to manage all the big data to support the decision making.
With BIM we can use a predictive risk management instead of a preventive one.
Why to use BIM?
Because it can support decisions based on different data:
- show building performance;
- smart materials are linked to database which represent building shape, performance and can monitor the end user;
- budgeting control
With BIM there is a different process, with a centralized view and total control of information. All the stakeholders can see information and follow the progresses. This is possible thanks to interoperability of software and thanks to cloud storage of huge amount of data.
User can collect data from many devices, it’s very important in this case to take care about privacy issues.
Bim use in different countries
BIM started in USA in the ‘80s, born from the need to find a smart design tool for big building sites.
In 2006 UK decides to introduce BIM as mandatory for public tendering.
In Italy there is still a 2D/paper construction process, it’s urgent to go at least to 3D, also for communication process with different stakeholders, to verify risks linked with the construction process. There is the need to go to 4D, 5D, etc since the first step of the project.
It’s important to use this kind of approach since the beginning, because it’s possible to decide everything in the early design. With this method the work phase is just an “assembly” phase, where stakeholders don’t have to make decisions.
BIM is useful to start managing conflicts since the very early phases, in this way it’s possible to ask the right question to a specific expert before the work starts.
Nowadays there is also the possibility to share information in real time all over the world. In this way decision makers and stakeholders can use that data to make choices.
Case study: The Mu.Sa project
In this project were applied sensor in an existing historical building. BIM is useful also to collect data during maintenance phase, in daily use. In this case study BIM was a monitoring tool, aiming to know building performance and inhabitant activities, to see how do they behave and how does the building behave during the time. Residents role is fundamental in the diagnostic phase.
BIM is not conceived to represent the real building, but is a tool to help the process.
The inception project
This is a set of models to access and understand the European cultural assets. Partners are trying to develop a platform where different actors can upload information about a specific part of the building stock, to provide case studies and strategies.
BIM is a tool, not a solution, but could help us to rethink our construction approach and is a way to keep costs under control.
