List documents relating to this part of the work, i.e. technical product/system specifications, test reports, appraisals, certification, etc. Normally they will be referred to in the text by the abbreviated title.

It is important to ensure that all personnel on site have access to accurate, up to date technical information on the many products, materials and equipment used on a project.  In most cases individual products are not used in isolation, but form part of a building process. Also a particular manufacturer and/or supplier requirements for handling, storage, preparation, installation, finishing and protection of their product can vary from what might be considered the norm.  Access to technical information can help overcome this potential problem.

Under certain conditions, a 30-year AMF/USG tile and Donn grid System Warranty can be applied for. Contact Rondo for information.

Modify or expand the clause to suit project or manufacturer/supplier requirements, options include:

• Modify the form to be used
• Commence the warranty from the date of purchase (check with the manufacturer/supplier)

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

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 general section 1235 SHOP DRAWINGS describes the process of submission and review of shop drawings.  Use this clause to describe the specific requirements of what the required shop drawings are to include.

Producer Statement - Design (PS1) required from consultants to be engaged by the Contractor. May involve a fee, check with supplier.

Producer Statement - Construction (PS3) required from installers as a condition of carrying out this work.

Producer Statement - Construction Review (PS4) required from consultants to be engaged by the Contractor.

A PS1 from an independent engineer can be provided for a fee.  Rondo are willing to facilitate this process.

This clause is setting a standard of performance for design by the contractor, to meet.  Specifiers should therefore consider adding some means of confirming (say by testing or certification) that the performance criteria will be or has been met.

Ensure correct information is supplied in 1220 PROJECT.

Use the following clause whether specifying by performance or not.

Load combinations are considered in accordance with AS/NZS 1170.0.
In some seismic areas the connection details may not be valid.  Refer to Rondo Building Services Pty Ltd for advice.

Delete this clause if acoustic requirements do not apply.

Modify to suit project requirements and Fire Report.

Note;  Group Number to be supplied by manufacturer, or for some materials and finishes, a generic Group Number from NZBC C/AS2, Table C1.2, may be able to be used.

Delete this clause if it does not apply.

Discuss with the manufacturers before specifying.

Delete this clause if it does not apply - not all systems can provide a FRR.

Note here the floor system specified elsewhere.
Modify to suit project requirements.

If this clause is not used and the SITE CONDITIONS clause cannot be complied with, then allowance needs to be made for a tile that will not sag over the construction period.

Use this clause for parts of the work where;

Special arrangements are required for notification for inspections.

These inspections may include 'Hold Points' or 'Notification Points'.

or

the manufacturer/supplier is required to carry out inspections outside their normal activities and provide reports or other documents in support of the work carried out.

or

the Contractor is required to carry out or engage consultants to carry out inspections of parts of the work.  It will typically be expected that the person carrying out the inspections will be required to provide producer statements in support of the work carried out.

Refer to Rondo for design assistance and advice.  This system is compatible with Rondo XPRESS® Drywall Grid Ceiling System.  Refer to 5313KL RONDO SYSTEMS - SHEET CEILINGS for plasterboard ceiling systems.

Note: Non-structural partition walls are not recommended as seismic restraints, unless specifically designed to do so.

As required by seismic and / or wind pressure requirements.

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.

Rewrite if the surface finish is other than vinyl sheet or film.

Rewrite for other tile finishes.

Rewrite for other ceiling materials such as plastic.

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

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

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.

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

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.

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.

Careful tile selection is important with plenums.

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.

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.

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

A PS1 from an independent engineer can be provided for a fee, this process is facilitated by Rondo.

Use these clauses if specifying by performance.

Typical Noise Control Recommendation Table

Conditions:

• Specific project requirements may be higher or lower than the above table.
• Type and location of noise source can affect the requirements.
• Flanking paths, ceiling spaces, gaps, doors etc, will need appropriate treatment.
• IIC will sometimes need to be considered for walls, structure and services.
• Schools, refer MOE, Design Quality Learning Spaces - Acoustics.
• Music performance spaces usually need specific design.

If a particular tile is selected, delete this clause.

Fill in project values, obtain information from the project structural engineer.
These values are critical to allow the Contractor to design the ceiling accurately.
Usually design for wind is only required if there are opening external windows/doors or other sources of wind pressure differential (including some roof spaces).
Ensure that all general information is available in this specification or drawings (for instance ceiling height etc.). Refer to AS/NZS 2785, Appendix B for a checklist of typical information.
