These initial results have enabled SID to deepen fundamental reflections at different levels of its wealth management strategy: construction, operation and maintenance of infrastructure, organization of business skills and internal resources, etc. Advances that also support him in his vision of BIM: a tool at the service of practices, placing the Human at the heart of projects.
In addition, this collaboration is fully in line with CSTB's research programs, dedicated to digital. The various actions undertaken contribute to improving skills, processes and know-how in the service of buildings, urban planning and the smart city.
Two large projects, carried out during this first phase of partnership, more specifically illustrate these advances: the adaptation of BIM tools to different trades and uses, with the Navy surveillance and expertise analysis laboratory (LASEM); and the experimentation of digital tools for the existing, with the Camp des Matelots in Versailles.
Digital Research & Development: the scope of the partnership
In April 2016, as part of its wealth management strategy, the Ministry of the Armed Forces, via SID, wanted to experiment with technologies linked to digital building (BIM - Building Information Model) and city (CIM - City Information Model) models. .
He then entered into a Research partnership with CSTB, aiming to transfer all of its infrastructures, ie 40% of French public heritage representing 30 million m² of usable area, to BIM, and allow its teams to work on a common digital base, from construction to operation of projects.
6 actions have been taken:
- Generate data in IFC and CityGML formats, from existing SID applications, and integrate them into BIM and CIM digital models;
- Develop a national “BIM-SID Charter” to structure a BIM protocol common to all new SID operations, facilitating dialogue with project management and optimizing the creation, at the end of the project, of a “File of Work Executed ”- DOE-BIM - for the operational phase of the building;
- Experiment with the work thus carried out on a pilot operation: BIM support, in design-build, of the Marine Monitoring and Expertise Analysis Laboratory (LASEM), delivered at the end of September 2017 in Brest. The 2017 BIM D'OR awarded this project a Silver BIM in the Operation-Maintenance category, the Jury having notably praised the replicable pilot approach thanks to a very open BIM convention;
- Develop a collaborative platform for storing, viewing and verifying BIM digital models, both compatible with the functionalities of the BIM-SID Charter and the data security requirements of SID;
- Develop a BIM protocol for operating the SID infrastructure for all construction, extension and renovation operations, facilitating data management during the operation phase;
- Study the impact of BIM on the organization, methodologies and professions of SID: impacts in terms of new professions and new missions, evolution of computer networks, new software tools to deploy, training needs…
- Thus structured, this Research partnership is based on complementary expertise and visions:
- The multi-business expertise of SID, which brings together architects, designers, operation managers, operators, managers. This diversity of skills has made it possible to extend the work undertaken in this partnership to the entire life cycle of the building, from its design to its operation, while structuring the work around a central question: how to adapt BIM to different business uses?
- The technical and scientific expertise of CSTB which supports actors and the industry in the digital transition, developing for them and with them collaborative tools and dedicated BIM protocols. Digital, on the scale of the Building, the Neighborhood and the City is also one of the main research themes of CSTB.
Feedback and lessons learned: focus on two experiments integrated into the partnership
Two years after the partnership was set up, the first results are now available.
The various actions implemented, most often carried out with the aim of replicating the approach, have generally enabled SID to refine its reflections and its strategy around BIM / CIM, within the framework of the management of its assets, nationwide.
In addition, they have also enabled CSTB to fuel its research on the operation and maintenance of structures via BIM, essential elements for ensuring an efficient digital transition over the entire building life cycle.
Two experiments particularly illustrate these advances:
- The adaptation of BIM tools to different trades and uses, within the framework of the design-build of the surveillance and expertise analysis laboratory of the Navy - LASEM (Brest). On this project, the first challenge was to generate structured data for the operation / maintenance phase. To do this, “business views” have, for example, been developed to allow different user profiles to better understand and use site and operation data.
- Experimentation with digital technologies for the existing, as part of the renovation of the Camp des Matelots (Versailles).
The central objective of this project was to transform the building and its existing information into BIM data. Different data acquisition systems were thus compared, before integrating the information obtained, combined with operating data, in a single model.
The “business views” developed for LASEM have been integrated into this model for a presentation adapted to the user's profile and thus, easier and faster use of BIM Operation.
And tomorrow: the prospects for partnership
Building on these first advances presented on July 4, 2018, the research partnership associating SID and CSTB continues around two main axes:
- Research on the collaborative BIM platform internal to the SID networks;
- The impact study of BIM on the trades and methodologies of SID, a service made up of professionals with very varied profiles. BIM, as it is understood within the framework of the SID-CSTB partnership, is above all a human issue. It must allow everyone to access a tool suited to their missions and skills. The implementation of a BIM approach therefore represents a major training challenge for SID. The work on uses carried out by CSTB will fuel reflection on the necessary training needs, targeted by user profiles, in order to further facilitate the appropriation of the tool within its structure. A detailed analysis of the organization of the service and its ecosystem (partners, subcontractors, etc.) will be implemented in parallel to identify the different user profiles, meet future users and understand their needs, expectations and constraints. test the tool and take their views into account.
“With this resolute anticipation, the SID wishes to facilitate the serene and precise analysis of the potentials of BIM in order to generate benefits for its missions of construction and management of the ministry's heritage. The SID, in this real challenge, sought to add the skills of an equally unique partner organization that it naturally found with CSTB, an organization whose expertise in the field is unanimously recognized and welcomed. "
General Bernard Fontan - Central Director of the Defense Infrastructure Service (SID)
“I welcome the major interest of this partnership with SID, which allows us to put BIM at the service of the evolution of practices at the heart of a unique organization. Human beings and different business uses are key issues in this major research program that we are developing with SID. The first experiments carried out on projects carried out by SID, on a large scale and over the entire life cycle of buildings from design to operation, are already advancing innovation, knowledge and practices professional.
