GIB Ensures Detailed Data for Specification with New BIM Objects

Building Information Modelling (BIM) is becoming an important tool and process in the industry, particularly for large and complex commercial jobs, but efficient and effective BIM modelling requires accurate and up-to-date BIM objects.

The advantages include improved, detailed information, like the ability for a quantity surveyor to identify the number of screws required or to test different scenarios or performance requirements such as calculating energy use. Significantly, it allows for better collaboration and communication between designers, engineers and contractors, allowing engineering to be refined and clashes such as health and safety issues to be identified and mitigated. By keeping all project data together in one place, BIM avoids data loss and is particularly helpful for future maintenance and alterations.

GIB has developed over 100 BIM objects that contain linked data to GIB systems and are now available on the GIB website as Revit files. The new BIM objects are available for GIB bracing, fire, and noise control systems, as well as standard walls. The objects include data, such as the fire rating, STC rating and BRANZ appraisal number, as well as the visual and graphical representation. This linked data allows designers to compile essential information in one place, make fast and accurate schedules and identify clashes or potential risk areas like penetrations in fire walls. CAD files are also available for all GIB systems.

Designers and contractors need to be certain that the data in every GIB BIM object is correct and relevant, and so GIB BIM objects for fire and acoustic systems have been BRANZ appraised. This is a New Zealand first and underscores Winstone Wallboard's commitment to supplying accurate technical information to the industry. The BRANZ appraisal means that the data within the GIB BIM object has been verified by a third party, giving designers peace of mind for specification and installation.

GIB Ezybrace Systems

GIB plasterboard has been made in NZ for NZ conditions since 1927.

Green Tag Certified

NZ Made

Due to the recent changes made to NZS 3604:2011 Winstone Wallboards has taken the opportunity to review the total GIB EzyBrace System to allow additional efficiencies to be achieved.

GIB EzyBrace Systems comply with the requirements of NZS 3604:2011, when designed and installed in accordance with this brochure. NZS 3604:2011 is an Acceptable Solution to NZBC Clause B1 Structure once referenced. Under normal conditions of dry internal use GIB EzyBrace Systems have a service life in excess of 50 years and satisfy the requirements of NZBC Clause B2 Durability.

GIB Ezybrace Systems are fully compliant with NZS 3604:2011, along with vigorous testing of all the systems using the BRANZ P21 Test and Evaluation Method (2010).

All GIB unfinished plasterboard sheet materials achieve a Group 1-S interior fire rating to NZBC C/AS2-AS6, Table 4.1, following testing in accordance with ISO 5660.1 and ISO 5660.2.

The GIB Fire Rated Systems technical literature has been providing clear instructions on building protection from fire for many years.

Green Tag Certified

NZ Made

GIB Fire Rated Systems have been appraised for use as fire-rated load bearing and non-load bearing framed constructions elements in buildings.

NZBC Clause B2 Durability: Under normal conditions of dry internal use GIB Fire Rated Systems have a serviceable life in excess of 50 years and satisfy the requirements of NZBC Clause B2.
NZBC Clauses C1 – C6 Protection from Fire: GIB Fire Rated Systems can be used to provide passive fire protection in accordance with the requirements of NZBC Clauses C1 - C6.
NZBC Clause C6 Structural Stability: In order to satisfy the requirements of this clause, designers must ensure that fire rated elements are supported by elements having at least the same Fire Resistance Rating (FRR). Collapse of elements having a lesser FRR shall not cause the consequential collapse of elements required to have a higher FRR.
NZBC Clause G6 Airborne and Impact Sound: For many specifications in the technical literature Sound Transmission Class (STC) and Impact Insulation Class (IIC) performances are given. For higher performances, including those required by NZBC Clause G6, reference should be made to the current version of ‘GIB Noise Control Systems’.

All GIB unfinished plasterboard sheet materials achieve a Group 1-S interior fire rating to NZBC C/AS2-AS6, Table 4.1, following testing in accordance with ISO 5660.1 and ISO 5660.2.

GIB Noise Control Systems

View Product

Winstone Wallboards Ltd offers a wide range of GIB wall and floor/ceiling noise control systems. GIB Noise Control Systems have been extensively independently tested and evaluated and can be depended on to perform.

Noise control plays an important role in office comfort, productivity and privacy/confidentiality. Studies show that a positive environment has a positive effect on business. Attention needs to be given to noise control, room acoustics, and services. Open plan offices require a degree of privacy which is achieved to some extent by masking sounds. Senior managers expect more noise control and require it for confidentiality. Seminar and meeting rooms, and walls between tenants need to protect the amenity value of users. Wall penetrating ceilings will provide a higher level of performance, thus making GIB Noise Control Systems the perfect solution.

Other areas requiring attention are those that endure noise disturbance from neighbouring rooms (adjacent, above or below) in the form of airborne sound from TV and voices, impacts from footsteps along corridors and stairs, or services like showers and toilets. Noise from impacts travels horizontally along floors as well as up and down; impact through walls can be a concern where there are no buffers from wardrobes or bathrooms.

Noise from lobbies, entertainment and conference rooms can require special attention as well.

Protection from external noise is important near main roads and airports, while room acoustic treatment around receptions in large foyers can aid intelligibility.

GIB Noise Control Systems are ideal for use in such situations.

In the opinion of BRANZ , the GIB Noise Control systems, if designed, and used, installed and maintained in accordance with with the statements and conditions of Appraisal No.394 [2017], will meet the following provisions of the NZBC:

Clause B1 Structure: Performance B1.3.1, B1.3.2 and B1.3.4.
Clause B2 Durability: Performance B2.3.1(a), B2.3.1(b), B2.3.1(c).
Clause C3 Spread of Fire: Performance C3.4(a) and C3.6
Clause F2 Hazardous Building Material: Performance F2.3.1
Clause G6 Airborne and Impact Sound: Performance G6.3.1 and G6.3.2.

All GIB unfinished plasterboard sheet materials achieve a Group 1-S interior fire rating to NZBC C/AS2-AS6, Table 4.1, following testing in accordance with ISO 5660.1 and ISO 5660.2.
