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 supply and installation of Rondo DONN® Exposed Grid Ceiling System, and the supply and installation of ceiling tiles.

It includes:

Modify / expand this clause to suit requirements of the final version of the section.

 

Rondo DONN® Exposed Grid Ceiling System can be used to support a wide range of ceiling tile types, refer to the separate tile Manufacturer's / supplier's for product details and to ensure compatibility with selected Rondo DONN® Exposed Grid Ceiling System.

 

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 in order 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.

 

The Rondo project specific documentation provides a similar level of documentation to shop drawings.  Shop drawings can be provided if the design service is not required.

 

The ceiling manufacturer/supplier will require some detailed project information to enable their specific design the ceiling system. Ensure the information is available in this specification and/or on the drawings (for instance ceiling height etc.).

Refer to AS/NZS 2785, Appendix B for typical project information requirements.

EXECUTION
Conditions
3.1
DELIVERY, STORAGE & HANDLING OF PRODUCTS

Refer to 1270 CONSTRUCTION for requirements relating to delivery, storage and handling of products.

Use this standard generic clause and if appropriate add additional special requirements.

3.2
ROUTINE MATTERS

Refer to 1250 TEMPORARY WORKS & SERVICES for protection requirements.

Refer to 1270 CONSTRUCTION for requirements relating to defective or damaged work, removal of protection and cleaning.

Use this standard generic clause and if appropriate add additional special requirements.

3.3
CO-ORDINATE SERVICES

Co-ordinate and co-operate with electrical and mechanical work to avoid conflict between suspension members and luminaires, diffusers, pipework and ducting. Confirm the provision of extra hangers and fixings.

 

Ensure co-operation with work in and above the ceiling, including the marking of specific ceiling tiles below major access points to above-ceiling services. Colour coded markings to follow the standards laid down by mechanical and electrical services.

 

Services and other attachments, attached to or supported by the ceiling grid system to AS/NZS 2785, ensure that:

  • items over 7.5kg and items under 7.5kg but falling greater than 3m, require a tether to AS/NZS 2785, anchored to structure.
  • items attached to the ceiling grid must be under 10kg mass, items over 10kg cannot be attached to the grid and must be independently supported.
  • unless designed otherwise, the ceiling systems total load of services and other attachments must not exceed 3kg/m².
  • light fittings installed to AS/NZS 2785 and NZS 4219.
  • ceiling system clearances to structure and services etc. that are not attached to the ceiling system, to NZS 4219, and/or NZS 4541 for sprinklers.

Note - Although items under 10kg mass are allowed, it is recommended that 7.5kg be considered the maximum for attaching to the grid under ULS conditions.

3.4
SITE CONDITIONS

Do not begin installation until the building is closed in, fully glazed, the roof watertight, and mechanical and electrical duct work above the ceiling completed.  To AS/NZS 2785, Appendix C, site Conditions, Installation and Inspections.

If fast track construction is used, this may not be possible and tiles must be selected accordingly.

3.5
RESPONSIBILITY

Ensure that conditions are suitable for the ceiling installation.

Installation
3.6
STANDARDS AND TOLERANCES

Refer to the general section 1270 CONSTRUCTION for general requirements.

Amend this clause to describe specific standards and tolerances to be achieved in carrying out this part of the work.  Although such tolerances are typically included in standards (NZS, AS/NZS etc) in certain circumstances it is worth restating these in this clause.

3.7
INSTALLATION - GENERAL

Install the Rondo DONN® Exposed Grid Ceiling System to AS/NZS 2785, Rondo Professional Design Manual, Rondo DONN® Exposed Grid Ceiling System Rondo brochure and Rondo Building Services Pty Ltd requirements, and to NZS 4219 where services are involved.  Fix, erect and fit to finish rigid, plumb, square and true to line and face.  Hangers and bracing are not to be fixed closer than 150mm to plenum building services.  Where components required cutting on site, use metal snips, fine-toothed band or hack saws.

Install all movement joints required.

Install Ceiling tiles to AS/NZS 2785, ceiling tile manufacturer's and Rondo Building Services Pty Ltd requirements.

3.8
INSTALLATION - SPECIFIC

Refer to SELECTIONS for Rondo Building Services Pty Ltd project specific design documentation.

3.9
INSTALL SEISMIC RESTRAINTS

Install ceiling system seismic restrains and bracing as required to prevent lateral movement and resist the imposed horizontal seismic force, to AS/NZS 2785.

Main items to consider:

  • If ceiling systems abut glazing, the horizontal seismic forces generated by the ceiling can damage the glazing.
  • If large runs of ceilings are terminated at bulkheads, the horizontal seismic forces generated by the ceiling can cause separation between the ceiling and bulkhead if not properly designed.
  • If the ceiling is terminated at a partition, design the partition to enable it to accept the seismic force generated by the ceiling.
  • If the partition is terminated at the ceiling, design above the ceiling line for the seismic force generated by the partition. This is normally achieved with continued, unlined studs or Tracklok bracing system to underside of the soffit.
3.10
PENETRATIONS

To AS/NZS 2785 and NZS 4219 generally, with sprinkler systems to NZS 4219 and/or NZS 4541, and to Rondo DONN® Exposed Grid Ceiling System Rondo brochure.  Accommodate recessed light fittings, air conditioning outlets and other electrical and/or mechanical services that are fixed to or pass through the ceiling system.

Provide independent support for these as necessary.

Careful tile selection is important with plenums.

3.11
ACCESSIBILITY

Provide access to the ceiling system and the in-ceiling and above-ceiling services so that maintenance and removal of any part can be carried out without damage to the ceiling system or panels.

As full access in all areas is clearly impractical, any special requirements for clear access will need to be defined; either by description here, or on the drawings.

3.12
ISOLATE

Isolate dissimilar metals with neoprene sheeting, tape or pipe lagging.

3.13
RETURN AIR PLENUM

Encapsulate tiles to prevent release of fibres into the ceiling space, air conditioning or ventilation system.  Clip tile down to the grid to stop lifting.

While this clause is written specifically for projects where the ceiling space is being used as a plenum, it may also be modified to suit particular projects which require some degree of assurance against the release of fibres, and/or the use of panel clips.

Completion & Commissioning
3.14
COMPLETION MATTERS

Refer to 1270 CONSTRUCTION for completion requirements and if required commissioning requirements.

Use this standard generic clause and if appropriate add additional special requirements.
