BIM and more
WHY THE BUILDING INFORMATION MODELING
BIM has been defined by the National Building Information Modeling Standards as “the act of creating an electronic model of a facility for the purpose of visualization, engineering analysis, conflict analysis, code criteria checking, cost engineering, as-built product, budgeting and many other purposes.”
The BIM method has the advantage to bring additional value to the project and to optimize data and information exchange. Furthermore it reduces project implementation times and improve costs forecasting. A digital model is realized through the use of model authoring software, a software designed for code and model checking and a simulations software.
The BIM model allows project information sharing among all players involved in the process. BIM is applied to the entire life cycle of a building, from its design to its demolition. Professionals involved in the design and execution phase can implement the model with the information and data of their area of expertise, thus reducing the typical loss of information distinctive of the traditional workflow.
Building Information Modeling marks the transition from a traditional 3D design to a design that can includes a single virtual model up to 7 dimensionals to which the fourth (4D) covers time, fifth (5D) costs, sixth (6D) sustainability and the seventh dimension (7D) is about facility management, in other words the operation and maintenance of the facility throughout the entire life cycle.
THE BIM USES
Analysis and Verifications
React specialists, members of the BIM User Group Italy, contributed to the drafting of UNI 11337 regulation that defines BIM standards and procedures. Building Information Modeling was introduced In the new Tenders Code of Conduct, in particular Article 23, paragraph 13, states that:
"Procurement stations may request for new public works, as well as for retrieval measures, retraining or others, primarily for complex jobs, the use of specific electronic methods and instruments referred to paragraph 1, letter h). These tools use interoperable platforms through non-proprietary open formats, in order not to restrict competition between technology providers and not limit the involvement of specific players among designers. The use of electronic methods and instruments may only be required by the procurement stations equipped with suitably trained personnel and with suitable monitoring systems. The Decree of the Ministry of Infrastructure and Transport identifies the timeframe for the progressive introduction of the obligation of the method, evaluated in relation to the type of works to be entrusted and taking into account the relevant costs as well as adequate monitoring systems. The use of such methodologies constitutes a criterion for the evaluation of the bid award criteria referred to in Article 38 ".
In addition, the "Baratono Decree" of the Ministry of Infrastructure and Transport has defined the road map for the progressive introduction of the obligation to use the BIM methodology in public works.
From the recent provisions of the Legislator, it is evident that the construction world needs to adapt to the new needs.
