Good morning, ladies and gentlemen! As instructed in our previous meeting, the subcommittee on building development has now drawn up a brief to submit to the firm’s architect. In short, the building would consist of two floors. There would be a storage area in the basement to be used by the research center as well as by other departments. We are, as you know, short of storage base, so the availability of a large basement would be a considerable advantage. The ground floor would be occupied by laboratories. Altogether there would be six labs. In addition, there would be six offices for the technicians, plus a general secretarial office and a reception area. The first floor would be occupied by the offices of Research and Development staff. There would be a suite of offices for the Research and Development Director as well as a general office for secretarial staff. It’s proposed to have a staff room with a small kitchen. This would serve both floors. There would also be a library for research documents and reference material. In addition, there would be a resource room in which audio visual equipment and other equipment of that sort could be stored. Finally, there would be a seminar room with closed circuit television. This room would also be used to present displays and demonstrations to visitors to the centre. The building would be of brick construction so it’s to conform to the general style of construction on the site. There would be a pitched roof. Wall and ceiling spaces would be insulated to conform to new building regulations.
