1. Executive Summary This report is for the assessment of proposed development consists of four storey mixed-use building containing cafe, pharmacy, medical centre, retail/commercial tenancy and one basement carparking. This primary purpose of this report is to provide an analysis of Building Code of Australia (BCA) assessment to identify the areas of noncompliance with the deemed-to-satisfy provisions of the BCA. A summary of all relevant clauses discussed in the report.

2. Background Henry Group Pty Ltd has been engaged by University of Newcastle, to determine compliance with the provisions of Building Code of Australia (BCA) for the proposed new commercial development located at University Drive NewCastle 2200.

3. Documentation The documents that referenced, reviewed and relied are lists below  Building Code of Australia (BCA) 2016  Guide to the Building Code of Australia (BCA) 2016  Architectural plans by University of Newcastle are as follow; A261_B_120511, A82_E_120511, A803_F_120511, A804_D_120511, A805_F_120511, A111_A_120606, A031_A_120511.

5. Building Code of Australia Assessment 5.1 Part A3 CLASSIFICATION OF BUILDINGS AND STRUCTURES BCA Clause A3.2 Classificatio ns

BCA requirement

Non-compliance

Class 5 – a building which is intended for commercial or professional services such as offices.

Comply with Class 5, 2nd storey to 4th storey intended to use for offices.

Class 6- a building where sale activity is carry out between vendor and public.

Comply with Class 6, there is a pharmacy at 1st storey which is a place for public to buy goods.

Class 7a – A building which is a carpark. Class 9a – generally a building which providing public services for health care services and a building which have a laboratory within the parts of the building also consider to this class.

Comply with Class 7a, the building has a carpark at basement. There is less information on usage of medical centre, however Class 9a is determine for medical centre at 1st storey and 2nd storey. The café will consider part of the Class 9a as the floor area is not more than 10% of 1st storey.

5.2 Part C1 FIRE RESISTANCE AND STABILITY BCA Clause

BCA requirement

Noncompliance

C1.1 Type of constructio n required

The proposed building has a storey of 5 and a class of 5, 6, 7a and 9a. This building is to design and construct in Type A fire-resisting construction with the fire resistance levels specified in Table 3 of Spec C1.1 of the BCA.

The building is to complies with Spec C1.1 Type A fire-resisting construction requirements.

C1.2 Calculation of rise in storeys

This calculation is to aid in classify required type of construction. The total of each storeys with the highest number that under the same roof defined as the rise in storeys.

The building has a rise in storeys of 5 including carpark basement. The basement carpark is 1m above from ground hence is consider as a storey.

C1.3 Buildings of multiple classificatio n

When a building has multiple classifications, the top storey classification is used to apply for the below storey. In this case, the proposed building top storey is Class 5 thus following the Table C1.1, Type A construction will be required.

Type A Construction must apply for this building. The proposed building is compliance readily achievable.

Note: FRLs still required for the different storey for different classifications. C1.4 Mixed Types of constructio n

Mixed types of construction only allow in one circumstance in which the different types of construction are separated from on another by a fire wall as described in C2.7(b).

The proposed building only needed to construct in Type A thus this clause is not applicable for this building.

C1.5 Two storey Class 2,3 or 9c buildings

Two storey Class 2 or 3 building shall classify Type B Construction but when that classes gain access to at least two exits or have own pathway to the road it’s could classify as Type C construction. The low rise Class 9c building which have sprinkler system not only needed to classify as Type C construction also must comply with all other relevant BCA provisions and compartment size specified in Table C2.2.

The proposed building is 5 storey Class 5 , 6 , 7a and 9 building hence not applicable for this clause.

C1.10 Fire hazard properties

The materials of fire hazard properties such as linings, materials and assemblies are must comply with Spec C1.10. This is to limit the spread of fire so that the building occupants have had time to evacuate.

There is no indication on materials use for the proposed buildings, however the proposed materials such as floor or wall finishes, insulation, assemblies are required to comply with Spec C1.10

5.3 Part C2 COMPARTMENTATION AND SEPARATION BCA Clause

BCA requirement

Non-compliance

C2.2 General floor area and volume limitations

The floor area and volume of the fire compartments in the building must not exceed the following size: Class 5 office – 8,000 m² and 48,000 m³ Class 6 retail, Class 9a Class 7a carpark – 5,000 m² and 30,000 m³.

The proposed building floor area and volume of the fire compartments are within the Type A Construction. Thus its complies with this clause.

Note: patients care for Class 9a

health care building is exclude from this area. The detail requirements mentioned in C2.5.

C2.3 Large isolated buildings

Class 5 to 9 building are to comply with fire compartment limit that set in Table C2.2 but when there is the case its over pass the limit, the C2.3 concessions clause comes in. As an example –the building allows to exceeds fire compartment limit if it is protected by sprinkler system comply with Spec E1.5 and emergency vehicle access is complying with C2.4(b).

The proposed building is not exceeding limit that specified in Table C2.2. This clause is not applicable for this building.

C2.4 Requiremen ts for open spaces and vehicular access

From site plan drawing, it does not comply as north and east side of the building do not have a pathway for vehicle access.

C2.5 Class 9a and 9c buildings

In order to minimize the spread of fire and smoke in health care building fire compartments in patient care areas are to separate but not exceeding 2000 m².

The information on architecture drawing is not stating any usage of patient care, ward area and Fire walls must be divided between so on. The details the remainder of the building and shall be provided fire compartment also for Type A and the standards construction; Specification C1.1 must follow C2.5 must apply to floors and ceiling. requirements. When ward floor area not more than 500 m², walls with a smoke-proof comply with Spec C2.5 must be use to separated. If Treatment areas is less than 1000m², the smoke-proof walls comply with Spec C2.5 must be use to separate from patient care area.

The ancillary use areas for an example; (i) Floor area with more than 30 m² which are used for food preparation such as Kitchen. (ii) A hyperbaric facility room (pressure chamber) (iii) Medical record storage with floor area more than 10m² (iv) The room where equipment with potential fire sources are used such as a laundry. The ancillary use areas are tend to have high potential fire hazard so that it must separate with FRL of not less than 60/60/60 from the patient care area.

C2.8 Separation of classificatio ns in the same storey

The class 6 on the 1st floor are required to separate from the class 9a with a higher FRL which is class 6 FRL of 180/180/180. The separation from 2nd floor to 4th floor is to be by Table 2 Spec C1.1.

Architecture drawing is not showing the information of FRL walls but compliance advice to structure engineer is that the fire walls are to be as per Table 3 Spec C1.1.

C2.9 Separation of classificatio ns in different storeys

The intent for this clause is to minimize the risk of fire between parts of a different classification building which is on above another. The floor between the Type A construction must comply with an FRL of specified in Table 3 of Spec C1.1.

Most possible to comply but structure engineer to ensure all the separation between storey classes are in accordance with Table 3 of Spec C1.1.
