Delete from the DOCUMENTS clause any document not cited. List any additional cited documents.
The following are related documents and if referred to in the work section need to be added to the list of DOCUMENTS.

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.

~ years to ~ years are the sort of warranty periods that can be expected depending on material selection and project conditions.  Check with the manufacturer/supplier for their specific periods.

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.

Steelformers offer an engineering design service, delivering project specific documentation prior to consent and tender as an alternative to the Shop Drawing process.

By contacting Steelformers through the Masterspec work section support function, the design service can be coordinated with this specification section and other consultant documentation.  Steelformers project specific documentation can be attached within the specification Contract Appendix.

Re-run the Q&A if required to obtain the Steelformers design service clause content.  Delete this clause if using the Steelformers design service.

Steelformers 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.

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

A PS1 from an Chartered Engineer can be provided for a fee.  Steelformers are willing to facilitate this

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 Chartered Engineer can be provided for a fee.  Steelformers are willing to facilitate this process.

This clause is setting a standard of performance for design to be met by the contractor.

Specifiers should therefore consider adding a 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 Steelformers for advice.

Steelformers ceiling battens can support ceilings linings weighing up to 25kg /m2.

Note - the nominal weight of a single layer of 13mm plasterboard is 12kg/m2.

GALVSTEEL® is manufactured by New Zealand Steel.

22mm and 35mm ceiling battens cut to required length [maximum length is 10m]. C-Channels are supplied in 6m lengths.

Steelformers Ceiling Batten System is not suitable for use in structural applications e.g. ceiling diaphragm, or as a component for FRR construction. Individual projects may require specialist detailing and development.  Technical assistance from Steelformers is available on request.  Check Steelformers data sheets and develop in conjunction with ceiling lining weights.

Expand this clause to describe project requirements.

Note - Consult a Registered Electrician for earthing requirements.

The galvanized steel clips are sourced in New Plymouth.  Clips are fixed to the sides of timber ceiling joists, truss chords, or floor joists.  Individual projects may require specialist detailing and development.  Technical assistance from Steelformers is available on request.

Check Steelformers data sheets and develop in conjunction with ceiling lining weights. Expand this clause to describe project requirements.

Note - Consult a Registered Electrician for earthing requirements.

Modify or delete this clause if using other sheet materials.

Fixing types vary for direct-fixing into steel or timber.

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

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

Direct fixed systems may be able to vary loads slightly from the above depending on fixing centres and lining capacity, discuss with manufacturer.  Also with direct-fixed systems, subject to design, small lightweight light fittings may be able to be fixed to; the lining (for recessed) or lining back support (for pendants).

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.

Refer to CO-ORDINATE SERVICES for anchoring services to the ceiling structure.

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.

Modify clause to suit project.

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

Use these clauses if specifying by performance.

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.

Fill in project values, obtain information from the project structural engineer.

These values come 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 other general information is available in this specification or on the drawings (for instance ceiling height etc.). Refer to AS/NZS 2785, Appendix B for further information required.

Delete the clause if it does not apply and the contractor is not expected to design.
