GENERAL

If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to amend some clauses to suit the final project-specific version.

 

The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.

 

This section relates to the manufacture, supply and installation of:

 

This section includes:

Note - the maximum ceiling drop for direct-fix ceilings is 200mm below the structural support.  Ceiling drops greater than 200mm require a suspended ceiling grid.

Modify or extend the above description to suit the project being specified.

 

Rondo Building Services Pty Ltd offer an engineering design service, delivering project specific documentation prior to consent and tender. A detailed wind and seismic report as part of the consultant supplied information may be required to undertake a design.

If required a PS1 from an independent engineer can be provided for a fee, this process is facilitated by Rondo. By contacting Rondo through the Masterspec work section support function, the design service can be coordinated with this specification section and other consultant documentation. Rondo project specific documentation can be attached within the specification Contract Appendix.

 

Rondo project specific documentation provides a similar level of documentation to Shop Drawings. Shop Drawings can be provided if the design service in not required.

To enable the manufacturer/supplier to specifically design the ceiling system, ensure sufficient information is available in this specification and/or on the drawings (for instance ceiling height etc.). Refer to AS/NZS 2785, Appendix B for a list of typical project information.

 

This section refers to a concealed direct fixed furring channel (or batten) system supporting screw-fixed flush-finished plasterboard or other sheet material.

 

Modify the relevant clauses to suit project requirements.
