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.

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 practical completion of the contract works (check with the manufacturer/supplier)

Stud framed systems maybe suitable for load bearing applications by specific design.

Specify for standard requirements unless there are particular design needs.  Most systems are available in 30, 60 and 120 minute fire resistance ratings and 30 through to 59dB sound transmission class ratings.

Used to batten over masonry and concrete walls, options to accommodate irregular wall surfaces and for acoustic requirements.

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.  Deflection head tracks are required for wall heights of 4800mm or greater, or as a requirement of the project, for example where studs are located under concrete slabs.  There is no requirement to isolate the track sections from the slab unless specifically stated.  Track sections are nominally 3000mm long.

Available to match track widths.

Designed to provide support to wall studs and prevent twisting of studs when wall linings are being fixed.  May be installed as a continuous nogging track (cut outs to accommodate studs) or individual nogs may be cut from the track.

Used as an alternative to Rondo Nogging track.  Can be installed after the framing is complete, providing faster overall installation time for wall framing.  Positioned to one side of the stud.

Rondo top hat sections used to backfit into notches cut into studs, alternatively steel angles may be riveted to studs where studs have been notched out.  Refer to Rondo Building Services Pty Ltd for further details including limitations on notch sizes.

Used to connect wall track to DUO® Exposed Ceiling Grid System.

Suitable for use with standard heavy duty stud/track connections if required for high lateral wall pressures.

Rondo PANTHER® Access Panel Systems are designed for internal installation to provide access to services.

Expand/modify clause to suit.  Rondo studs maybe used with extruded aluminium track sections designed to accommodate the stud profile and linings, typically providing visible aluminium trim.  The aluminium track section is used in place of the Rondo steel wall track section.

Used to provide support to cupboards, hand rails, televisions etc.  Do not use CCA treated timber.

The nogging bracket is available in 2.4 m lengths and can be cut to suit extent of 17mm thick plywood required.  The bracket is screw fixed to the stud, the plywood is then fixed to the bracket.

Studs may be spliced to increase their length, modify clause to specifically exclude splicing if appropriate.

Expand this clause to suit project requirements.

Acoustic Chase walls, two parallel walls with no bridging between.

Expand this clause to suit project requirements.

Bridged chase walls , used to accommodate large bore pipes, air conditioning ducts or similar services concealed between two lines of parallel wall framing.  The walls are cross braced at regular intervals.  The bracing can either be plasterboard, stud or track section.

tracks are installed on edge so as not to bridge the full width of the cavity between wall linings.

Staggered stud steel wall frame systems are designed to provide effective resistance to sound transmission and acoustic impact when lining boards are attached in various configurations.  An alternative acoustic solution to staggered stud wall system is the use of Rondo Quiet Studs.

Boxed studs (0.50, 0.55 and 0.75 BMT) or back to back studs (1.15 BMT) are used to provide greater rigidity at openings and can accommodate window openings up to 1500mm in width and door openings up to 1000mm in width. For Larger openings use Duplex studs & fixing brackets.

Options for screw fixing are:

To screw fix through the web of stud, or

Screw fix with 35 x 35 x 0.70 Rondo steel angle at one end of the nog and screw fix through the web of the stud at the other.

Amend the clause to suit project requirements.

Web cleats can be used to allow for higher than standard lateral wall pressures.  Delete if web cleats are not required.

Hole sizes are dependent on stud sizes with limitations on size and spacing/separation.

Electrical services can be run through the preformed service holes of the 0.50, 0.55 and 0.75 BMT studs without requiring grommets (due to the flaring design of the hole).  Grommets are required to pre punched holes and any other holes formed through the stud.

Notching may be provided to accommodate bath, shower detailing etc.  Contact Rondo Building Services Pty Ltd for notching limitations.

Window and door framing require special detailing to prevent long term serviceability problems.  This detailing is in the form of additional fixings and framing members which carry the extra loadings in these areas.  Expand clause to suit.

Copper and brass piping and fittings should be isolated from direct contact with the steel framing.

Generally services are run through the pre-punched service holes, additional service holes can be formed, with limitations on size and separation.
