UNI 11337: 2017. BIM (Building Information Modeling) and lighting | BIMCommunity
The UNI 11337 Standard represents an important reference for the whole project chain and a big step forward under the regulatory
The UNI 11337 Standard represents an important reference for the whole project chain and a big step forward under the regulatory aspect aimed at regulating the methodology underlying the BIM
BIM, Building Information Modeling, is understood as the combination of the new digital technologies and the methodological approach to the management of the contract. The word "information" in the acronym is the key that distinguishes the complexity of the BIM model from a traditional 3D model. The information contained in a BIM project is coherent with each other and allows the coordination between the design and implementation of the work.
In Italy, the first UNI 11337 was published in 2009 and introduced the concept of information, interoperability and unambiguous identification of a work in the construction sector, even anticipating the British PAS 1192, published in 2013. In 2017 the technical standard UNI 11337: 2017 now represents an expanded reality, divided into 10 parts of which 5 already published and translated into English.
The working group involved in the technical table is made up of about fifty people representing the entire supply chain: designers, companies, trade associations, professional associations, producers, certification bodies, accreditation bodies, software houses, institutions public and ministerial offices and universities. By 2019 you will have a complete picture of all parts updated and published.
The Norma is aimed at all building works and any type of product, whether it is a new building or infrastructure, or a conservation, redevelopment of the environment or built heritage, and finally any type of process, from the concept to the production and operation. The law also provides for the temporal examination of the progressive obligatory nature of the provisions, which will start from 2019 for works above 100 million euros to reach 2025 for amounts of less than one million euros.
The contents of the different parts of the text
Part 1. Models, data and information objects for products and processes
The first part defines the general terminology, the differences between the models, the elaborates and the digital information objects and defines the general concepts related to the nature and origin of the information, starting from the definition of the data, to arrive at the definition of the most complex structures , such as the structure of information vehicles and the information structure of products / processes in the construction industry. In particular, the structure of the process is organized in stages and phases of the information process, virtualization/multimedia simulation.
Part 2. Criteria for the naming and classification of models, products, and processes
Part 2 of UNI 11337, still under development, identifies a classification and naming system for works, objects and activities. In concrete terms, it will try to define the identifying attributes for the automatic verification of the congruity of data between models, drawings and objects, also providing a method to expand and customize the attributes for each project. This will have repercussions on the price lists of the building works and on the specifications.
Part 3. Models for the collection, organization and storage of technical information for construction products
Part 3 of UNI 11337, published as a technical specification in 2015 and now being revised, aims to indicate a structured operational model to collect and store data and technical information, intended as information attributes, of works, objects and activities, through predefined templates. The technical specification allows to define the characteristic and characterizing attributes and divides them between LOG, geometrical informative attributes, and LOI, non-geometrical informative attributes. This allows gathering information with measurable and non-measurable descriptions.
Part 4. Evolution and informative development of models, designs and objects
Part 4 of UNI 11337 focuses on what are the levels of development of objects and models, the so-called LOD , which in the Italian standard become the level of development of digital objects ; for these Italian LODs a classification is proposed on a scale from "A" to "G", as an alternative to the British proposal (from "1" to "6") and to the United States (from "100" to "500"). Also interesting is the introduction of specific LODs for restoration, a singular approach on the international scene and clearly linked to the peculiarity of the Italian building heritage.
Part 5. Information flows in the digitized processes
Part 5 of UNI 11337, published and available from 2017, defines the roles, requirements and flows necessary for the production, management and transmission of information and their connection and interaction in the digitized construction processes. In other words, the standard introduces the concepts of the Information Document, the Information Management offer and the Information Management plan. It also aims to explain the coordination of graphic models, the analysis of interference and inconsistencies, also called clash detection and code checking, and the levels of model verification. Finally, this part of the standard provides the requirements of the Data Sharing Environment (ACDat or the equivalent English abbreviation CDE).
Part 6. Guideline for the preparation of the information documents
Part 6 of UNI 11337, published and available from 2017, is purely operational, an aid to the contracting authority and to the client: for this reason it was drafted in the form of a technical report. Writing a correct and complete information sheet prevents misunderstandings, loss of time and problems at all stages of the process.
Part 7. Requirements for knowledge, skills and competence of the figures involved in management and information modeling
Part 7 of UNI 11337, published in 2018, identifies four types of professionals: the information manager, or BIM manager , the manager of the ACDat, or CDE manager , the coordinator of information flows, or BIM coordinator , and the operator advanced management and information modeling, or BIM specialist .
Part 8. Integrated Processes of Information and Decision Management
Part 8 of UNI 11337, whose publication is scheduled for 2019, analyzes the integration processes between activities and information figures and traditional activities and figures in the construction sector. In practice this part should act as a trait d'union between the national standard, project management and EN ISO 19650.
Part 9. Information management during operation
Part 9 of UNI 11337, whose publication is scheduled for 2019, is to guarantee the "quality" of the real estate for both the production phase and the use of the asset, validating the work of different market operators. The standard assumes that at present the knowledge of the buildings is proposed in a heterogeneous and uncoordinated way, on the basis of different formats proposed by different operators (public and private, institutional and non), with consequent confusion both by the actors of the building process that of "occasional" operators (in particular small buyers). This part of the series will develop the digital file of the building.
Part 10. Guidelines for the digital information management of administrative practices
The tenth part of UNI 11337, whose writing will take place after the publication of the other works, expresses the general information management criteria, in digital form, aimed at standardizing data exchange procedures and protocols of administrative practices related to buildings, such as authorizations, permits, complaints or reports.
