CONDITIONS AND LIMITATIONS The report does not provide guidance in respect of areas, which are used for bulk storage, processing of flammable liquids, explosive materials, multiple fire ignitions or sabotage of existing fire safety systems.

Apart from where noted in the specific sections of this report, we have not verified information provided by external parties and assume that the remainder of the building will comply with the DtS provisions of the NCC Volume One – BCA.

Any application of the content of this report should be made taking into full account the following items:

• observations of the building fire safety systems and fire hazards listed in this report have been based on examination of documentation made available.

• any change in the information referenced including product design as detailed in this report to suit future re-organisation or planning will require further assessment to confirm compliance with the intent of the design objectives.

• the data, methodologies, calculations and conclusions documented within this report specifically relate to the product and must not be used for any other purpose.

• specifically, the report does not consider property damage; e.g. building and contents damage caused by fire, potential increased insurance liability and loss of business continuity.

• this report considers a single point of fire as a source of ignition. • the design complies with the current DtS provisions of the BCA

except for the specific performance solutions identified within this report.

• figures provided within the report are indicative only. Full and appropriate detail is expected to be provided within discipline specific engineering specifications and associated detail design drawings by others.

• this report should not be considered as a stand alone document but read as part of the buildings suite of approved documents including architectural drawings, fire safety systems detail including specifications and associated drawings as well as the buildings design, construction, installation and commissioning approvals.

Potential risks of incendiary are limited in the scope of engineering design. Conventional building design can only provide limited protection against malicious attack; for example, large scale incendiary and multiple ignition sources can potentially overwhelm some fire safety systems.

Strategies such as security, housekeeping and other management procedures may be more effective than additional fire protection in addressing arson events.

This report is applicable to the Project only. It does not consider property damage to the building as a result of the alternative building solutions addressed in the evaluations.

A number of issues within the NCC Volume One – BCA are interpretive in nature. Where these issues are encountered, interpretations are made that are consistent with standard industry practice.

This report is prepared in good faith and with due care for information purposes only, and should not be relied upon as providing any warranty or guarantee. In particular, attention is drawn to the nature of the inspection and investigations undertaken and the limitations these impose in determining with accuracy the state of the product applied within the building, its services or equipment and life safety.

Ignis Solutions’ involvement in the Project is limited to the role outlined in the service acceptance. This report reflects that role. Any reliance on, or use of, this report for purposes outside the scope of service is at the user’s own risk.

Ignis Solutions shall not be held liable for any loss or damage resulting from any defect of the building or its services or equipment or for any non compliance of the building or its services or equipment with any legislative or operational requirement, whether or not such defect or non-compliance is referred to or reported upon in this report, unless such defect or non-compliance should have been apparent to a competent engineer undertaking the assessment of the type undertaken for the purpose of preparation of this report.

Ignis Solutions has carefully reviewed and applied to the best of our ability the requirements of State/Territory Legislation, the BCA and the International Fire Engineering Guidelines.
