Creating smart cities: A CSI exclusive

When building smart cities, the specifications are of paramount importance. In effect they become a form of governance for the whole project, specifying outcomes suitable not only for a building, but also as life-cycle work for the whole city as a system.

Specifying offsite construction: A CSI exclusive

Offsite construction is part of a gradual move toward a more manufacturing-based process in the construction industry. It allows significant amounts of building construction to be performed in a controlled environment, and depending on project needs, on a near assembly-line basis. This is beneficial for worker safety and project...
