I agree that a BSc in Arch Technology is not the equivalent of an Hons Degree in Architecture which is a five year degree. Thirty years ago there was no such thing as an Architectural Technologist - you had Architects and Draughtsmen. Over the last three decades the paralell professions of Architecture and Architectural Technology have evolved to the extent that most Architects nowadays spend their time on design work - primarily concerned with the appearance and aesthetics of buildings. Technologists are primarily concerned with the 'nuts and bolts' of how buildings go together - issues such as Building Regs Compliance, Construction detailing, Fire Safety, Performance etc. I believe it is now fair to say that if you have an Architect doing the latter he is now doing a Technologists job rather than vice versa.
I have heard the difference between the two professions described as ''An Architect needs to know enough about construction to design a building while a Technologist needs to know enough about design to construct a building.''
Engineering is further removed from either of the Architectural professions and certainly neither a Technologist or an Architect would qualify for membership of the I.E.I. By the same token an engineer could not qualify for membership of the R.I.A.I.
Both Engineers and Architects because the professions are longer established are better organised than Architectural Technologists but that could well change in the near future as the I.A.T.G.N. (Irish Architectural Technology Graduate Network) is in the throes of negotiatons with the Law Society, the R.I.A.I. and the C.I.A.T. in the U.K. (Chartered Insitute of Architectural Technologists) with a view to either an amalgamation or setting up a new institute.
