CMB is one of the largest construction companies in the Italian market, working both in infrastructure and civil buildings (mainly hospitals). CMB has been active in construction since 1908.
In recent years the CMB business has moved from simple construction contracts, both public and private, to more complex forms of contracts, like PPP and Concession contract. Since 2000, CMB has become more and more involved in the design, construction and facility management processes.
CMB’s interest in the whole supply chain of design, construction and facility management processes had continued to grow substantially and in 2012 the management of the company decided to measure the impact of BIM by starting a collaboration with the University of Brescia and some of the most important software companies involved in BIM.

During 2012 CMB developed a series of tests for field BIM and laser scanning and developed parts of 3D models based on projects managed in the traditional way. At the end of 2012 CMB decided to start its “
pilot” project of testing some of the main aspects of BIM implementation within the management of a hospital project: CMB BIM Pilot Project. CMB decided to start the pilot project as a “
parallel activity”, and continued to use the traditional methods for the real management of the Project with the aim of trying to make comparisons between the traditional and BIM methods.
The CMB BIM Pilot Project is based on a Hospital Refurbishment and Extension Project: the San Gerardo Hospital in Monza, close to Milan.
June 2013, a patient in a wheelchair can not make a 360 ° rotation, as required by law, due to insufficient space.
CMB BIM Pilot Project is almost at the end of its first phase (120 days) with a lot of interesting results coming from the tests developed. These results include the construction of the 3D model, quantity take off, coordination of designs, development of 2D deliverables and model checking.
Among other software tested and utilized in the pilot project, and thanks to the collaboration with the University of Brescia, CMB decided to test Solibri’s product for model checking and code checking, in order to measure a series of benchmarks in the Design Validation process. Providing an optimized and well coordinated design has been one of the main goals of the CMB BIM Project.
CMB is currently analyzing the results but the management of the company is already scheduling improvements to its processes and the measures being tested as a second phase of the BIM Project.

Solibri Model Checker – A solution for model checking and code checking
Thanks to Prof. Angelo Camillo Ciribini and his students of the University of Brescia, CMB had the opportunity of testing Solibri Model Checker (SMC) in the Design Validation Process.
Thanks to Silvia Mastrolembo, a Civil Engineer just graduated at the University of Brescia, SMC has been used to check the 3D model developed by the BIM team, in order to analyse the quality of the model (model checking) and the compliance to codes (code checking) such as accessibility for people with some form of disability (e.g., people who use wheelchairs).
“We tested Solibri and its way of offering automated reports” (the following figures are abstracts from the CMB BIM Pilot Project).
Conclusions
“The CMB BIM Pilot Project is still in a development phase but we certainly can say that the use of Solibri Model Checker has already demonstrated a powerful and very worthy tribute to the process of design and model validation.”
June 2013, tolerances: an example of integrated design: the installation model built in compliance with the structural one.
