Building Anatomy NCC 2019 amendment 1 Report Report No.: 210142r2/NCC

1.0. REPORT SUMMARY

Table 1.1 below lists the BCA DtS provisions compliance matters that must be considered and where further detail is required to be submitted at the construction certificate phase. Table 1.1: Summary

Item Description / Comment

Note: The class 5 ancillary office building is a separate standalone building for the purposes of this assessment.

Performance solutions Deemed to satisfy departures from the BCA to be addressed with a performance solution that satisfy the NCC governing requirements in Part A2. 1. D2.20

Swinging doors

A swinging door in a required exit or forming part of a required exit, must swing in the direction of egress unless it serves a building or part with a floor area not more than 200sqm, it is the only required exit from the building or part and it is fitted with a device for holding the door open. The southern exit door, and the new western exit door serving the new staircase, both swing against the direction of egress. Obtain a performance solution to permit the door swing against the direction of egress.

2. F1.0 Deemed to satisfy provisions (weather proofing of external walls)

Performance Requirement FP1.4, for the prevention of the penetration of water through external walls, must be complied with. There are no Deemed-to-Satisfy Provisions for this Performance Requirement in respect of external walls. As part of the construction certificate application, a performance solution to satisfy FP1.4 must be developed and submitted for assessment and acceptance by the Certifying Authority. The performance solution must be determined in accordance with A2.2(3) and A2.2(4) as applicable. It is noted that for a building of this size and nature, a façade engineer need not provide the performance solution and this can come from the project architect, or other suitably qualified registered certifier, or BCA consultant.

Compliance readily achievable The DA plans submitted to the Consent Authority do not contain full BCA compliance details as full BCA compliance is not a head of consideration for the Consent Authority during the DA assessment phase. It is expected however that at the construction certificate phase, the level of detail provided to the certifying authority will be at a level that confirms strict compliance with the BCA. These items are summarised below. 3. D1.10

Discharge from exits

If a required exit leads to an open space, the path of travel to the road must have an unobstructed width throughout of not less than—

(i) the minimum width of the required exit; or

(ii) 1m,

Whichever is the greater

It is noted that when discharging from the new stairway serving level one, the path of travel to the road is along the below blue line heading south. Pedestrian line marking and potentially bollards to prevent cars from blocking the exit path should be considered.

3.6. Legislative Framework

Section 4.15 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 National Construction Code as in force at the time the application for the construction certificate was made, including any subsequent construction certificate for staging purposes.

4.0. BUILDING NCC DESCRIPTION

4.1. NCC Description This review has been undertaken against the National Construction Code (NCC) 2019 amendment 1. The building is described in the following sections.

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

The new addition increases the rise in storeys of the office building to two (2). There are two (2) storeys contained within. The other existing buildings on the lot are not more than 2 storeys.

4.3. Building Classifications (Clause A3.2) Building Levels Classification

Ancillary office building

Ground floor Class 5 office (ancillary to the class 9b use)

Level one Class 5 office (ancillary to the class 9b use)


of 62


4.4. Effective Height (Clause A1.1) The effective height of the building is 3.05m. Lowest floor level counted in the rise in storeys: 28,500 Floor of top storey counted in the rise in storeys: 31,550 31,550 – 28,500 = 3,050.

Section 2: Courtesy of AUDAA Pty Ltd

4.5. Type of Construction (Table C1.1) The class 5 ancillary office building part is required to be of Type ‘C’ Construction. Refer to section 4.2 for calculation of the rise in storeys applied to table C1.1 below.


4.6. Floor Area and Volume Limitations (Table C2.2) The class 6 retail on ground floor, and class 7a car park is within the limitations of Type A construction. The class 2 residential flat building is not subject to the floor area and volume limitations of table C2.2.

of 62


4.7. Fire protection and structural capacity (Clause 143) Being new construction and therefore no change of use to an existing building, the provisions of clause 143 of the Environmental Planning and Assessment Regulation do not apply.

4.8. Referral of certain plans and specifications to New South Wales Fire Brigades

Clause 144 of the Environmental Planning and Assessment Regulation 2000 describes the circumstances in which referral to FRNSW is required. Those circumstances are for a class 9b and class 5 building that is proposed to have:

i. a fire compartment with a total floor area of more than 2,000 square metres, or

ii. that is proposed to have a total floor area of more than 6,000 square metres, and where the plans and specifications for the work provide for a performance solution to meet the performance requirements contained in any one or more of the Category 2 fire safety provisions, Category 2 fire safety provision means the following provisions of the Building Code of Australia, namely, CP9, EP1.3, EP1.4, EP1.6, EP2.2 and EP3.2 in Volume One of that Code. The proposal does not incorporate a fire compartment greater than 2,000m² and the building is less than 6,000m², therefore the provisions of clause 144 of the Environmental Planning and Assessment Regulation and referral to Fire and Rescue NSW will not be required.

6.0. CONCLUSION NCC Compliance Demonstrating full compliance with the National Construction Code (NCC) at DA assessment stage is not prescribed under Section 4.15 of the Environmental Planning & Assessment Act 1979. The Consent Authority however has an obligation to consider whether the proposed development application is indicatively capable of complying with the NCC and without significant modification when an application for a construction certificate is made. In this regard, the concept design submitted to council for approval contains no departures from the deemed to satisfy provisions of the NCC. Existing windows however that are on ground floor of the ancillary class 5 office building that are within 3m of a fire source feature will be addressed with a performance solution from a fire engineer and will likely require heat attenuation screens of some kind (these are shown in the DA drawings). In addition, the ground floor egress doors to the south (the main entry doorway), and to the west (the side exit) swing against the direction of egress and will require a performance solution to permit the direction of swing. Weather Proofing of External Walls It is recognised that under Part F1.0 of the NCC, there are no Deemed-to-Satisfy provisions for performance requirement FP1.4 in respect of external walls. As part of the construction certificate application, a performance solution to satisfy FP1.4 must be developed and submitted for assessment and acceptance by the Certifying Authority. The performance solution must be determined in accordance with A2.2(3) and A2.2(4) as applicable. Disability (Access to Premises – buildings) Standard 2010 The Certifying Authority is to consider the Disability (Access to Premises – buildings) Standard 2010 and determine whether the affected part upgrade should be applied to the proposal and to what extent. The proposal relates to the rection of a second storey to an existing building and therefore the standard is triggered. Despite this, the additional storey is subject to a concession under Part D3 that mitigates the need for wheelchair access to level one and as such the proposal does not include lift access to level one. That being said and to avoid doubt, wheelchair entry into the ground floor has been proposed along with a modification to the ground floor amenities to incorporate a unisex accessible sanitary compartment. The design therefore addresses the affected part upgrade within the Premises Standard. Clause 145 (EP&A Regulation 2000) DA Consistency Construction certificate plans when lodged with the certifying authority are expected to contain appropriate detail illustrating full compliance with the NCC. It is our opinion those plans will not demand the need for any significant design changes that in turn would necessitate the submission of an application under Section 4.55 of the Environmental Planning and Assessment Act 1979.
