This review is provided in order to assist Council consider whether the proposal, as lodged, is indicatively capable of complying with the BCA and without significant modification to those plans for which approval is sought. This review does not include a detailed assessment against the ‘Adaptable Housing’ Code provisions (AS4299-1995).

2.3. Basis of Report This report is based upon:

A desktop review of the documentation submitted for assessment (refer to drawing schedule section 1.2); and

The Deemed-to-Satisfy provisions of Parts C, D, E and F of the National

Construction Code Series (volume 1) 2016.

2.4. Referenced Documents The following documentation was relied upon when preparing this report:

The performance and deemed-to-satisfy provisions of the National Construction

Code 2016 (BCA) incorporating the NSW Appendices where applicable.

Environmental Planning & Assessment Act 1979.

Environmental Planning & Assessment Regulation 2000. 2.5. Limitations and Exclusions

The limitations and exclusions of this report are as follows: This report is based on a review of the referenced documents.

No assessment has been undertaken with respect to the Disability Discrimination

Act 1992 (DDA). Separate advice from an appropriately qualified access consultant should be obtained by the client to be satisfied that their obligations under the DDA have been addressed.

Please note that whilst the BCA specifies a minimum standard of compliance with AS1428.1 and Part D3 of the BCA for access and facilities for people with disabilities, compliance with such requirements may not necessarily preclude the possibility of a future complaint made under the Disability Discrimination Act 1992 (DDA). The DDA is a complaint based legislation and is presently not identified by the State Building Codes and Regulations. In this regard the client should be satisfied that their obligations under the DDA have been addressed.

This Report does not address issues in relation to the following:

of 54

a) The structural adequacy of the building including the Fire Resistance Levels (FRL’s) of any existing building elements (unless specifically referred to).

b) The design, maintenance or operation of any existing electrical, mechanical, hydraulic or fire protection services.

c) Environmental Planning and Assessment Act and Regulations. d) Local Government Act and Regulations. e) Occupational Health and Safety Act and Regulations. f) WorkCover Authority requirements. g) Requirements of other Regulatory Authorities including, but not limited to,

Telstra, Sydney Water, Electricity Supply Authority, RTA, Council and the like. h) Disability Discrimination Act. i) Construction Safety Act. j) Any previous conditions of Development Consent issued by the relevant Local

Building Certificates Australia Pty Ltd cannot guarantee acceptance of this report by the Local Council, NSW Fire Brigades or other approval authorities.

Without written permission from Building Certificates Australia Pty Ltd, no part of this document may be reproduced in any form or by any means. This report is based solely on client instructions, and therefore should not be used by any third party without prior knowledge of such instructions.

2.6. Legislative Framework

Section 79C of the Environmental Planning and Assessment Act provides the matters of consideration that the consent authority must take into account in the determination of a development application. Once development consent is granted, and pursuant to Clause 145 of the Environmental Planning and Assessment Regulations 2000, a certifying authority must not issue a construction certificate for building work unless: (a1) the plans and specifications for the building include such matters as each

relevant BASIX certificate requires, and (a) the design and construction of the building (as depicted in the plans and

specifications and as described in any other information furnished to the certifying authority under clause 140) are not inconsistent with the development consent, and

(b) the proposed building (not being a temporary building) will comply with the

relevant requirements of the Building Code of Australia (as in force at the time the application for the construction certificate was made).

of 54

Compliance with the National Construction Code The BCA is a performance based document whereby compliance can be achieved by satisfying the deemed to satisfy requirements or by formulating an alternative solution to address the relevant performance requirements. As indicated above, the requirements of the Environmental Planning and Assessment Regulations 2000 requires all new building works to comply with the relevant requirements of the BCA (as in force at the time the application for the construction certificate was made). This means that the plans and documentation submitted with the construction certificate (CC) application must demonstrate full compliance with the relevant provisions of the Building Code of Australia. Disability (Access to Premises — Buildings) Standards 2010 Disability (Access to Premises — Buildings) Standards 2010 is applicable to this development as a certificate under Part 4A of the EP&A Act 1979 will be sought. At the time an application is made to the consent authority for a construction certificate, full disclosure as to who the applicant for the construction certificate is must form part of said application. Should the applicant be a tenant in a multi-tenanted building, a concession will be applied and the ‘affected part’ upgrade with the Premises Standard will not apply. If however the applicant is the building owner, the affected part upgrade will apply. It is noted that his standard does not however apply to this building as it is a new build.

2.7. Terminology

National Construction Code (NCC) / Building Code of Australia (BCA) - Document published on behalf of the Australian Building Codes Board. The BCA is a uniform set of technical provisions for the design and construction of buildings and other structures throughout Australia and is adopted in NSW under the provisions of the Environmental Planning & Assessment Act & Regulation.

Fire Resistance Level (FRL) - means the grading periods in minutes tested in accordance with AS 1530.4-2005 for the following criteria -

(a) structural adequacy; and (b) integrity; and (c) insulation, and expressed in that order. Fire Source Feature (FSF) - the far boundary of a road adjoining the allotment; or

a side or rear boundary of the allotment; or an external wall of another building on the allotment which is not a Class 10 building.

Open space - means a space on the allotment, or a roof or other part of the building suitably protected from fire, open to the sky and connected directly with a public road.

of 54

Performance Requirements of the BCA - A Building Solution will comply with the BCA if it satisfies the Performance Requirements. A Performance requirement states the level of performance that a Building Solution must achieve. Compliance with the Performance Requirements can only be achieved by- (a) complying with the Deemed-to-Satisfy Provisions; or (b) formulating an Alternative Solution which-

(i) complies with the Performance Requirements; or (ii) is shown to be at least equivalent to the Deemed-to-Satisfy Provisions; or

(c) a combination of (a) and (b).

Sole occupancy unit - means a room or other part of a building for occupation by one or joint owner, lessee, tenant, or other occupier to the exclusion of any other owner, lessee, tenant, or other occupier.

BUILDING DESCRIPTION – PROPOSED DEVELOPMENT

2.8. Building Code of Australia Description For the purposes of the National Construction Code Volume 1, otherwise known as the Building Code of Australia (BCA) 2016 the proposed development is described in the following sections.

2.9. Rise in Storeys (RIS) (Clause C1.2)

The overall building has a rise in storeys of three (3). There are four (4) storeys contained within the building.

of 54

2.10. Building Classifications (Clause A3.2)

The building has been classified in accordance with the table below.

BUILDING LEVELS PROPOSED CLASSIFICATION

Basement Level

Ground floor – Level 2

Class 7a (car park)

Class 3 (boarding house)

2.11. Effective Height (Clause A1.1)

The effective height of the building is 6 metres. Highest RL taken = 16.885 Lowest RL taken = 10.885

2.12. Type of Construction (Table C1.1)

The building is required to be of Type ‘A’ Construction.

of 54

2.13. Floor Area and Volume Limitations (Table C2.2)

The proposed building is Type A construction. The Class 3 portions of the building are not subject to any floor area and volume limitations of C2.2 of the BCA. Table 3 of Specification C1.1 and C3.11 of the BCA regulate compartmentation and separation provisions applicable to Class 3 buildings or building portions. The class 7a basement car park sits well below the required threshold for its classification.

2.14. Fire protection and structural capacity (Clause 143)

If your development incorporates a Change of Use, Category 1 fire safety measures must be considered and implemented in to the design as applicable. EP1.3: A fire hydrant system (required) EP1.4: An automatic fire suppression system EP1.6: Suitable facilities must be provided to the degree necessary in a

building to co-ordinate fire brigade intervention (required) EP2.1: Sleeping Accommodation, occupants must be provided with automatic

warning EP2.2: Conditions in any evacuation route must be maintained for the period

of time occupants take to evacuate (required) EP3.2: One or more passenger lifts fitted as emergency lifts to serve each floor

served by the lifts in a building must be installed to facilitate the activities of the fire brigade and other emergency services personnel (required)

This is a new build and therefore the change of use provisions under clause 143 do not apply.

2.15. Fire Brigade referral (Clause 144)

A referral to Fire and Rescue NSW under Clause 144 will not be required as a result of the proposed works as the building does not have a fire compartment greater than 2000m² and the building’s overall floor area is not greater than 6000m².

of 54

3.0. FIRE SAFETY SCHEDULES 3.1. Proposed Fire Safety Schedule

As a result of the works proposed under this development application, the DRAFT fire safety schedule for the site will be as follows. The final fire safety schedule is to be prepared for issue of the Construction Certificate.

Essential Fire and Other Safety Measures

TBA

Prior to the issue of the construction certificate confirmation must be provided to the certifying authority confirming if the car park ventilation system will operate in a manner that may unduly contribute to the spread of smoke from one fire

compartment to another fire compartment. The concept design at this stage does not provide full mechanical details yet it is anticipated that the car park ventilation system will penetrate the roof of the car park and discharge directly to open space

without passing through another fire compartment.

Wall wetting drencher systems (Eastern fire isolated exit glazed wall facing east east)

BCA Clause C3.4 and AS 2118.2-1995

Hydrant coverage – Hydrant coverage is required as the building’s floor area is proposed to be greater than 500m². Whether the hydrant coverage will be provided from the street or by an internal hydrant system with pressure delivered by a hydrant booster assembly remains to be seen. Prior to the issue of a construction certificate a suitably qualified and practicing hydraulic engineer must confirm any existing street hydrant is located such that the required hose reel reach will be achieved as well as the required pressure and flow rates. The assessment is to include an enquiry to the regulatory authority Sydney Water to determine if the existing pressure and flow rates are adequate to serve the entire building. It is noted that the proposed DA drawings accommodate internal hydrants and a hydrant booster assembly; and the above draft fire safety schedule includes internal hydrants however in the event street coverage is achieved the booster assembly and internal hydrant points will be deleted from the plans and hydrants may be deleted from the building’s fire safety schedule.

of 54

3.2. Certification of Essential Fire Safety Measures

Pursuant to Section 169 of the Environmental Planning and Assessment Regulations 2000, it will be necessary for the owner of the building, on completion of work to furnish a Final Fire Safety Certificate with regard to each essential fire safety measure identified in the proposed Fire Safety Schedule listed above. The final fire safety certificate must state that each essential fire safety measure specified in the fire safety schedule for the building to which the certificate relates: (a) has been assessed by a properly qualified Fire Safety Practitioner, and (b) was found, when it was assessed, to be capable of performing to at least the

standard required by the current fire safety schedule for the building for which the certificate is issued.

Every year, the owner(s) will need to submit an Annual Fire Safety Statement to the Local Council and the NSW Fire Brigades, which confirms that all essential fire safety measures have been tested and maintained and perform to the original design and installation standard. A copy of the Annual Fire Safety Statement must also be displayed in a prominent areas of the buildings (i.e. the main entrance foyers).

of 54

4.0. CONCLUSION

Although demonstrating full compliance with the BCA at DA assessment stage is not a prescribed head of consideration under Section 79C of the Environmental Planning & Assessment Act 1979, Council has an obligation to consider whether the proposal, as lodged, is indicatively capable of complying with the BCA and without significant modification to those plans for which approval is sought. In this regard, the concept design submitted to council for approval exhibits three specific departures from the deemed to satisfy provisions of the BCA that are to be addressed by way of fire engineering to achieve the relevant BCA performance requirements. The DtS departures are:

1. D1.7(b)(ii) Travel via fire-isolated exits (the discharge area is not open for at least 2/3 of its perimeter).

2. D1.7(c) Travel via fire-isolated exits (the path of travel from the discharge point to open space necessitates an occupant to pass by openings in the building’s external wall that are unprotected).

3. E1.3 Fire Hydrants (the location of the fire hydrant booster assembly does not comply with AS2419.1; and the proposed shield wall does not strictly comply with the minimum dimensions in AS2419.1).

To address these DtS departures, a qualified C10 accredited fire engineer is required to prepare a report in accordance with Part A0.7 of the BCA to ensure the relevant performance requirement/s have been met. The justification of these DtS departures by means of performance solutions will satisfy the requirements of the BCA, thus the design will comply.

At the time a construction certificate is lodged with the certifying authority it is expected that the construction certificate plans will be advanced in order to illustrate more detailed compliance with the BCA, as an example those DtS provisions within our clause by clause assessment referred to as having ‘compliance readily achievable’ (CRA) and other relevant services. It is our opinion that the advanced construction drawings that are lodged in order to satisfy the requirements of the BCA (in force at the time the construction certificate application is lodged) will not demand the need for any significant design changes that in turn would necessitate the submission of an application under Section 96 of the Environmental Planning and Assessment Act 1979. Finally, we draw Council’s attention to the requirements of clause 145 of the Environmental Planning & Assessment Regulation 2000, and suggest that detailed & specific BCA compliance matters shall be addressed to the satisfaction of the appointed Certifying Authority prior to the issue of the Construction Certificate and therefore achieving the necessary BCA compliance.

APPENDIX B: BCA REQUIREMENTS - CLAUSE BY CLAUSE ASSESSMENT

Noting that the current level of documentation is for assessment purposes related to the development application stage, an indicative compliance assessment of the referenced documents identified in section 1.2 of this report has been undertaken against the Deemed-to-Satisfy Provisions of the National Building Code of Australia 2016 (BCA). In Table 4.1 below is a summary of the Deemed-to-Satisfy Provisions of the BCA. All Deemed-to-Satisfy clauses that are applicable to the subject building have been referred to below, including a comment adjacent to each clause of the proposal’s ability to satisfy each respective clause.

The abbreviations outlined below have been used in the following tables:

N/A The Deemed-to-Satisfy clause does not apply to the subject Building.

Complies The relevant provisions of the Deemed-to-Satisfy clause have been

demonstrated by the proposed design and existing building features.

CRA ‘Compliance Readily Achievable’. It is considered that the level of detail included in the CC documentation will not determine strict compliance with the individual BCA clause requirements. Further certification well be required prior to the issue of the Construction Certificate.

C1.1 Type of construction required

CRA The building is to be constructed of Type ‘A’ fire resisting construction in accordance with Specification C1.1 of the BCA and the external cladding / façade must be non-combustible unless it complies with specification C1.1 - 2.4 ‘Attachments not to impair fire-resistance’. Prior to the issue of a construction certificate a schedule is to be submitted to the certifying authority detailing the FRL’s of the proposed wall systems and external cladding systems. Note: Non-combustible roof allowance – Specification C1.1 – 3.5 ‘Roof concession’ applies to this proposed class 3 building to allow the roof to be non-combustible in lieu of complying with Table 3 of spec. C1.1. Note: Class 3 concession – Specification C1.1 – 3.10 Concession for class 3 buildings permits the building to be constructed of timber framing throughout; non-combustible material throughout; or a combination of both, provided insulation in cavity walls is non-combustible and the building is fitted with an automatic smoke alarm system complying with Specification E2.2a. Despite this it does not appear as though the building will apply this concession.

C1.2 Calculation of rise in storeys

This spandrel must have an FRL not less than 60/60/60. Full design specification and drawings showing the extent of the spandrel and the proposed FRL must be submitted to the certifying authority prior to the issue of a construction certificate. In addition to the complying vertical spandrel protection, the windows also have a horizontal projection of not less than 1100mm separating them from the window openings below however the horizontal slab projection does not extend either side of the window by at least 450mm. This is inconsequential as the vertical spandrel protection already complies.
