3.3  Ceiling Heights and Voids

The Contractor shall ensure that the void above the ceiling is adequate for the proper installation and co-ordination of the utilities services, and for future maintenance.

Suspended ceilings shall be readily demountable without suffering damage or becoming soiled and must be easily cleaned.  Frequently accessed voids shall be fitted with robust hinged locking doors or hatches.  

Service access points should be avoided in plasterboard/plywood ceilings within public areas.  Where this is genuinely unavoidable, access points shall be designed as part of the architectural form and shall be fixed securely utilising security screws and locks as appropriate, and in accordance with the principles of creating a safe environment.
