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's and/or supplier's 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.

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)

Delete clause if using QUALIFICATIONS WORKERS - INDUSTRY QUALIFICATIONS REQUIREMENTS.

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 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.

Rondo KEY-LOCK offers a system of top cross rails, furring channels, battens and clips, allowing for a range of spans and suspension point spacings.  The systems can be used in both fire rated and non fire rated suspended ceilings, eaves linings, direct fixed battens and bulkhead installations.

KEY-LOCK Ceiling System can also be installed with Acoustic Mounts.

Can also produce profiles in custom lengths and radii for curved ceilings.

Individual projects may require specialist detailing and development.

State if the system is to be fire-rated.

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

Refer to Rondo for design assistance and advice.

Refer to Rondo for design assistance and advice.  Suitable for:

• Concealed ceiling systems
• Plasterboard, fibrous plaster and fibre
• Direct fix or fully suspended applications
• Seamless transitions from concealed to exposed grid ceilings
• Bulkhead and boxed soffits
• Corridors , without the use of suspension hangers
• Fire-rated applications
• Seismic requirements
• Acoustic requirements

This system is compatible with Rondo DONN® Exposed Grid Ceiling System.  Refer to:

5311RT RONDO SYSTEMS - TILE CEILINGS for the supply and installation of Rondo DONN® Exposed Grid Ceiling System.

This system is used to achieve greater spanning distances than KEY-LOCK and/or when it is difficult to install a suspended system.

G2 refers to a steel grade designation under formability grades, Z275 refers to a zinc coating class with a coating mass of 275g/m².

Available in a range of widths (51mm, 64mm, 76mm, 92mm & 150mm) and BMT options (0.50, 0.55, 0.75 & 1.15).  Studs are designed to friction fit into tracks, with options for staggered studs within a larger track section for acoustic rated walls.

Tracks accommodate the friction fitting of studs into the track system.  The tracks hold the studs in position until the lining board is fitted and also allow a slip joint for movement in the structure, for this reason the lining is not fixed into the track section unless specifically stated / detailed.

Options include standard wall tracks, flexible wall tracks, deflection head tracks and slotted deflection head tracks.  There is no requirement to isolate the track sections from a slab unless specifically stated.  Track sections are nominally 3000mm long.

Mechanical joints are used where the spans of the ceiling joists exceed those allowable for friction joints.

Use when connecting to concrete soffits.

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

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

Confirm loadings with manufacturer.

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

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).

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.

Confirm with Manufacturer/supplier or Structural Engineer.

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 for the seismic force generated by the ceiling.

If the partition is terminated at the ceiling, design for the seismic force generated by the partition.

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.
