Optimizing the operation and maintenance of buildings using BIM

BIM-Operation helps to optimize the quality of structures, their management and maintenance, throughout their lifespan. To deploy its use, it is essential to develop tools that can be used by all players in the operation and maintenance chain. This is the stake of the partnership initiated by SEQENS, a subsidiary of Action Logement, managing a stock of more than 100 housing units in Île-de-France, and the Center Scientifique et Technique du Bâtiment (CSTB).

The two players combine their expertise to experiment and demonstrate the effectiveness of a new environment for collecting and sharing BIM data, updated and accessible in real time by all stakeholders, in the service of housing operations. . This innovative tool will allow optimized management of parks, for the benefit of service providers, occupants, project owners and lessors.

The challenge of the SEQENS - CSTB partnership: to experiment and then put into production a new BIM-Management-Operation-Maintenance (GEM) tool, at the service of housing

BIM-GEM improves the management, rental, upkeep and maintenance processes of buildings. However, if BIM Design-Construction is used more and more, BIM-GEM remains to be developed, especially in the housing sector. The stakes are high, most of the costs of a building being concentrated on this phase.

To enable and support the deployment of BIM-GEM, the development of operational tools, accessible to all players involved in building management, is essential. The partnership forged by SEQENS, a social landlord in the Ile-de-France region, and CSTB, a public establishment serving innovation in the building industry, is part of this dynamic.

Objective: to obtain a proof of concept for a new environment for collecting and sharing BIM data in real time (ECPD-BIM), making the link between all the key information in the life of the structure, from its construction to its use, then put it into production.

Developed by CSTB, the ECPD-BIM tool was thus tested for 4 months, as part of a specific use case, adapted to the specific needs and configurations of housing managed by SEQENS.

This experimentation phase demonstrated the interest of the solution for SEQENS 'activities, both in the initialization phase, which enables the company's information systems to be fed from design BIM data, and in the building operations, where field information is centralized in a unified model, for distribution to employees. ECPD-BIM also opens up opportunities for SEQENS to imagine new applications for collecting and sharing field information.

The benefits of use will be multiple:

• For lessors and project owners, optimize operating costs;
• For staff working on buildings and service providers, have all the data relating to a fleet, updated in real time, facilitating its management and maintenance
• For the occupants, gain in comfort and optimize rental charges.

SEQENS and CSTB are now giving themselves one year to improve and industrialize this ECPD-BIM prototype, designed to be accessible and usable by all players in the Management-Operation-Maintenance chain.

SEQENS - CSTB: complementary expertise, put at the service of the digital transition of housing

2nd social enterprise for housing in Ile-de-France, SEQENS is a committed social landlord, organizing its development in particular around:

• Prioritizing sustainable and energy-efficient housing;
• The quality of the environment and the comfort of life of the inhabitants, at the level of the district as well as of housing;
• Maintaining social ties and the involvement of occupants through various social and solidarity initiatives;
• Proximity, with tenants, but also with all stakeholders.

In this context, SEQENS wanted to initiate an innovative experimental approach to optimize the management of its fleet. It has thus approached the Scientific and Technical Center for Building:

"The partnership started at the end of 2020 with CSTB is an opportunity for Seqens, in perfect harmony with the digital transformation of the group. And the results are already there! We have already been able to benefit from their know-how and develop a solution of digital continuity, perfectly suited to the needs of a social landlord. Seqens wants to be a pioneer, to pave the way for other donors but above all and above all to be a pioneer, particularly in the BIM-CIM approach. is also part of the more global approach taken by Seqens in favor of the digitization of procedures for a better knowledge and more efficient management of its social stock, and with a single objective: the improvement of the living environment of its tenants. " Pascal VAN LAETHEM, Managing Director of SEQENS

CSTB deploys its multidisciplinary skills in a systemic approach, integrating all the challenges of the building, neighborhoods and cities, at the service of stakeholders, in particular in the digital field. Around this theme, it supports project owners, asset managers, communities, etc., in information management, the development of multi-criteria collaborative tools, training, etc. He thus carries out numerous Research & Development work around BIM, in particular in the Operation phase (creation of digital twins, development of tailor-made visualization and interpretation tools, services for managers, operators and occupants, etc.)

CSTB is now making this expertise available to SEQENS, for the experimentation of a new ECPD-BIM, dedicated to the operation of housing:

"CSTB is proud to be associated with SEQENS 'innovative approach to experimenting with the possibilities offered by BIM for the operation of its housing stock. In the long term, it will make it possible to offer this environment for collecting and sharing data. BIM in real time (ECPD-BIM) on a larger scale, and thus to support the actors of construction and housing in the digital transition. This partnership seems to me fundamental to develop innovative, efficient and reproducible approaches and tools, to the whole of the sector. This is the whole issue of partnership research at CSTB as we develop it and implement it with Seqens. " Etienne CREPON - President of the Scientific and Technical Center for Building
