2. progetti 2 BCV since 1973 BCV progetti firm, established in 1973 in Milan by Giulio Ballio, Giovanni Colombo and Alberto Vintani, provides a wide range of professional high quality services in structural engineering. Nowadays the firm, located in Milan, is managed by six senior partners. In addition to the partners BCV organization consists of other eight graduate engineers plus necessary draftsmen. Roughly 30000 engineer/hours are yearly provided. The various character of individual experiences resulted in a diversified areas of activities. Various aspects of structural design are currently managed: general design, detailed design, structural optimization, supervising of construction, test and monitoring planning, problem identification and rehabilitation, analysis and design of opto mechanical equipments.
