You could submit a DDA Impact Statement, as a response, outlining insufficient managerial procedures, (security staff only 9-4), and the inadquate accommodation on ground and first floor. Remedial work, (refuges, evac lifts etc) are unreasonable costings. I have experience of project managers that have succesfully applied the aforementioned in refurbs of existing premises, its rarely applied in new builds because Building Regs - Approved Doc M, (Access), requirements are incorporated into the design.
Food for thought though......assuming the accommodation is for able bodied students, what existing managerial procedures are there in place for a resident student who breaks his leg playing sport etc; and is living on the 2nd 3rd 4th floors.........
