Interior layout design guide

[SeaBass]

There is, or was, an ergonomics type design guide for interior floor plan lay outs which covered minimum gangway widths, space factor between desks, clear space required in front of filing cabinets, minimum sales floor aisle widths and similar. I think that it is either a CIBSE or a RIBA guide, but I can?t remember or find it on-line.  Can anyone point me in the right direction?

sounds like the RIBA metric handbook.
