The double challenge of the Agrate300 site
CMB has implemented technical and construction solutions suited to the future use of the production plant
but has also been able to propose work management and coordination methods according to tight timeframes and fixed intermediate objectives. This result has been achieved thanks to the implementation of a model – based on 3D modelling and the consolidated BIM methodology – in continuous evolution and shared with suppliers, designers and the client.20-TONNE “WAFFLE SLABS”

Technical Description
The new plant of the global company STMicroelectronics at Agrate Brianza extends over a surface area of 23 thousand sq.m. CMB will build its structural skeleton and envelope. The construction is made up of building bodies that, except for the entrance (used for offices) are intended for industrial use.
Every technical and building solution of the different parts has been designed according to the future production use: an innovative line for processing silicon wafers for the production of microchips.
To guarantee the necessary air-flows for the production plants, specific action has been taken on both the structures and on the envelope. Specifically, the metallic structures have been treated with a particular water-based painting cycle subject to pre-certification with laboratory tests. The envelope has exposed sandwich panels alternated with ventilated facades with coverings in stoneware and in composite aluminium, and with storm-resistant and sound-proof ribbon windows with high performance technical louvers and sun screens.
The truss roof
The plant’s metal roof is composed of 22 63-meter trusses of light and with a weight of 92 tons. Made with a system of reticular beams, braces and purlins in large-scale metal carpentry, the work required months of analysis for the complex assembly phase.
