In the construction sector, which is one of the major goals of the new economy, the company is aiming at a new constructive practice and upgrading of the built, using ICT (information and communications technology) technologies. So the focus is on new operating and organizational models of sustainable building processes in the architecture, engineering and construction sectors, which are based on three-dimensional models of digital technology BIM (building information modeling). It is intended as a human activity that improves building workflows and, through software and IFACs (industry foundation classes), manages flexibility, coordinates and optimizes operational choices on time, economic, and environmental sustainability parameters. The goal is a new interoperable building process that involves designers, contractors and businesses from programming to lifecycle building and maintenance through the integrated project delivery of the building. Dynamic architectures, interactive with efficient technological and constructive systems, are integrated with innovative products of complex nature and bi-directional performance, engineered, with energy storage and renewable resources. The methodologies are based, above all, on the adoption of BIM technologies with the digital project manager and the use of robotic technological tools. Digitization is applied for the design and construction of architectural and infrastructure artifacts, in interaction with intelligent, adaptive, nanotechnical and user-friendly materials and climate. The results are aimed at efficient buildings with user comfort and safety, accuracy, and risk monitoring with remote monitoring, highlighting VDC (visual design construction) in CID (computational intelligent design). 展开更多
