1.0 INTRODUCTION

1.1 GENERAL

NBRS Architecture have been engaged by Adco Constructions Pty Ltd to document the design for

the North Kellyville New Primary School, on the new site at Hezlett Road Kellyville for the Department

of Education.

As part of the design process a review has been undertaken of the proposed design against current

building regulations and to ensure that the design meets the appropriate building regulations,

including the provision of equitable access for all occupants.

This report sets out the outcome of the BCA Compliance and Access review, and has been prepared

to accompany the Construction Certificate Application.

The review compares the proposed design, against the requirements set out in the following

documents:

• The Building Code of Australia 2016 version (BCA) and

• The associated relevant standards

The proposed design for the development is represented in the following plans prepared by NBRS

Architecture which have been used as part of this review.

1.4 BCA REQUIREMENTS

The Building Code of Australia (BCA) sets out number of Performance Requirements that a building

solution must meet to achieve a reasonable level of safety, access to buildings, and functional

performance.

Where due to the configuration within individual building or site applications, the detailed design

does not meet the Deemed to Satisfy Provisions of the BCA, there is an opportunity for the design

to be assessed as an Alternative Solution, against the Performance Requirements of the BCA.

Any alternative Performance Solutions will be subject to the approval of the Principal Certifying

Authority.

The requirements for the building are based on the scale of the building, the number of occupants

and the usage of the building.

1.5 BUILDING HEIGHT, RISE IN STOREYS & EFFECTIVE HEIGHT

The building has a rise of storey of 2.

A total floor area of 7,948 m2

The building has an effective height of 6m.

Proposed School Site



2.0 BCA DEEMED TO SATISFY PROVISIONS

2.1 PART A – FIRE COMPARTMENTS AND FIRE RATINGS

The proposed building is considered as one Class 9b School development with a few areas of Class

5 office use associated with the main class 9b use of the site.

A building of two storeys with a class 9b use is required to be of Type B construction under clause

C1.1 and Table C1.1 of the BCA.

The building has a floor area of 7,948 m2, which exceeds the maximum area permitted for a building

of Type B construction (max. 5,500 m2). To address this the building is proposed to be of Type A

construction which is permitted to be of up to 8,000 m2. Therefore the building will meet the Deemed

to Satisfy provisions for the size of the fire compartment.

2.2 BUILDING FLOOR AREAS & COMPARTMENTATION

The building regulations limit the floor area of a building based on the use and the type of

construction.

For buildings of Type A construction the maximum floor area is 8,000 m2 or a volume of 48,000 m3.

The impacts of changing from type B construction to type A construction is that:

- Fire rating requirements for the building increases. The floor structural fire rating is increased

to floors having a FRL of 120/120/120.

- Fire rated spandrels are required to effectively fire separate each floor level.

2.3 BOUNDARY SEPARATION

The proposed building is located centrally on the site and away from the perimeter site boundaries.

Therefore no specific fire rating is required due to proximity to the site boundaries and other

buildings.

2.4 PART C- FIRE RESISTANCE

The Following table sets out the requirements for fire resistance dependent upon the classification

and distance of the building from the site boundaries or other buildings, taken from Clause 3.1 and

Table 3 of Specification C1.1. Table 2- Required Fire ratings for Class 9b Usage

POTENTIAL NON-COMPLIANCE NO. 1 Table 3 of Specification C1.1. requires that all structural columns in the external wall are required to

have a structural fire rating of FRL 120/--/-- or FRL 120/60/30 when more than 18m from a fire

source feature.

Within the design the external columns to the upper floor are not planned to be fire rated and this is

a non-compliance to Specification C1.1 and Table 3 and is to be addressed as a Performance

Solution within a fire engineered assessment, to be undertaken.

VERTICAL SEPARATION OF OPENINGS

As the building is to be of Type A construction Clause C2.6 of the BCA requires openings in external

walls that are located above each other to be provided with fire protection to prevent fire transfer

from one floor to the next. This is either by way of a vertical fire rated spandrel or a horizontal fire

rated projection above the lower opening.

Within the design the concrete upper level floor extends out past the line of the external wall to

provide protection above the opening in the lower level, but the projection does not meet the detail

requirements of Clause C2.6 as the projection is only 800mm.

POTENTIAL NON-COMPLIANCE NO. 2 The details of the horizontal projection not being the minimum required by Clause C2.6 is a non-

compliance and will need to be either extended to meet the requirements of Clause C2.6 or assessed

as a Fire Engineered Performance Solution to show that the design meets the associated

Performance Requirement of CP2. Performance Solutions are permitted based on Clause A05 of the

BCA 2016.

Solution

ENTERTAINMENT VENUE FIRE SEPARATION REQUIREMENTS.

The new Multipurpose Hall and Gym are not considered to be “Entertainment Venues”, however the

NSW DOE Education Facilities Standard and Guidelines (EFSG) sets out specific design

requirements for School halls and Gyms, due to the potential for the facilities to be used by the

community. This includes the requirement for store rooms to have a FRL 60/60/60 fire separation

from other areas.

2.5 PART D – ACCESS AND EGRESS

The requirements for access to and egress from a building are dependent upon the number of

occupants within the building and their characteristics.

The new facilities will be design for approximately 1000 students and associated staff.

NUMBER OF EXITS

A class 9b Educational School building is required by Clause D1.2 to have at least two exits from

each level.

TRAVEL DISTANCE TO EXITS

Travel distances to exits is set by Clause D1.4 which requires the following:

General Areas

• No point on the floor of each level is to be more than 40m from one of two exits with travel to

a point of choice of two exits within 20m.



• A maximum of 60 m between two exits measured through the point of choice.

• The travel distance from upper level down to ground level and to an outside Open Space is to

be a maximum of 80m.

EXITS PROVIDED

The design includes 5 stairs connecting the ground and first floor levels and a multiple exits from

the ground floor level directly to outside, in multiple directions.

2.5.3.1 LEVEL 1 FLOOR LEVEL

Within the design on Level 1 there are multiple exits from the different areas of the building as

follows:

- All home bases have a door leading directly to outside which ensures short travel distances to

an exit.

- The administration office and staff area, the Library and the hall all have an exit directly to

outside that ensures travel distances to outside of less than 40m as well as alternate exits via

the central courtyard.

- The exit from the Special programs area is via the ramp and stair which lead down to ground

level and to outside. In this case the exit is via a ramp or stair and therefore the ramp or stair is

considered to be the defined “Exit” and travel to outside open space is less than the maximum

permitted of 80m.

Figure 3- Level 1 Floor Plan


Within the design on Level 2 due to the location of the 5 stairs, travel distances from the

classrooms and all areas is less than 40m to one of two exits and less than 20m to a point of

choice.

Within the design the travel distance from some areas via the stairways to ground level and to

open space are up to 90m which is more than the maximum 80m permitted under Clause

D1.9 of the BCA.This is to be addressed as a Performance Solution to show that the design

meets the appropriate performance requirement for the provisions of exits.

It is noted that the central open walkway crossover requires the occupant to entry back into

the building before proceeding to one of the stair exits. The doors to the central open walkway

are to be unlocked while the school is occupied and may be locked for security purposes after

hours. This is considered appropriate and the likelihood of the doors being accidently locked

(a) A non-fire-isolated stairway or non-fire-

isolated ramp serving as a required exit must

provide a continuous means of travel by its

own flights and landings from every storey

served to the level at which egress to a road

or open space is provided.

(b) In a Class 2, 3 or 4

(c) In a Class 5, 6, 7, 8 or 9 building, the

distance from any point on a floor to a point

of egress to a road or open space by way of a

required non-fire-isolated stairway or non-fire-

isolated ramp must not exceed 80 m.

(d) In

Exits must be provided from a

building to allow occupants to

evacuate safely, with their

number, location and

dimensions being appropriate

to—

(a) the travel distance; and

(b) the number, mobility and

EXIT WIDTH

The required exit width is based on the number of occupants within the area.

NSW D1.6 requires that exit widths in a class 9b school to be at least 1m wide for up to 100

occupants of an area plus 250mm for each additional 25 occupants above 100.

Where there are more than 200 occupants, D1.6 requires a width of 2m plus 0.5m per 60

occupants where the exit path involves steps or 75 occupants when stairs are not included.


The lower level (Level 1) includes a number of different areas and functions, which is set out in the

table below.

Space Area Occupant Density Occupants

9 Home bases 25 students + 1 staff per room 234

3 special programs 12 students + 1 Staff per room 39

Administration office 460 10m2/p 46

Library 260 2m2/p 130

Library office 170 10m2/p 17

Multipurpose hall. 320 1m2/p 320

Total 786

For the 786 occupants the total clear width required is 6.5 m for exits without stairs and 7m for exits

involving stairs.

There are multiple exits from the ground floor with some areas having an exit directly to outside and

others sharing the exits from the central court.

The following table sets out the areas and their exits.

Space Occupants Exits

9 Home bases 234 Shared exits with central court

3 special programs 39 Exit via western corner

Administration office 46 Exit directly to outside via double doors

Library 130 Exit directly to outside via double doors

Library office 17 Exit via main library area

Multipurpose hall. 320 Multiple exits directly to outside

The ground floor exits are also shared with the occupants that have used the 4 central courtyard

stairs.

The exits from the courtyard areas are:

- Exit to the western corner which has a clear width of 3m and provides an exit for the occupants

from:

o Central Stair 1, (172 occupants)

o Western home bases ( 130 Occupants)

o Special Programs area ( 39 occupants)

- Exit to the south western corner which has a clear width of minimum 3m and provides exits for

occupants from:

o Central Stair 2, (172 occupants)

o Hall ( 100 occupants)

- The main entry / exit to south eastern corner which has a clear width minimum 4m and provides

an exit for occupants from:

o Central Stair 3 (172 occupants)

o Central Stair 4 (172 occupants)

o Northern corner home bases (72)

- The exit adjacent to stair 5 has a double door with a clear width of at least 1.5m and provides

an exit for occupants from:

o Stair 5 (118 occupants)

o Northern corner home bases (32 occupants)

The following figure shows the ground floor exits.



Figure 5- Ground Floor (Level 1) Exits

The 4 central stairs each have a clear width of 1.75m and the eastern end stair has a clear width of

1.2m giving a total clear width of 8.2m.

Therefore the current design stairs have sufficient clear width for the number of occupants.


The Upper Level (Level 2) includes a total of 31 home bases (classrooms) each could be expected

to accommodate up to 25 students plus one teacher. This would give a total number of occupants

on the level of 775 students and 31 staff, or 806 total.

For the 806 occupants the total clear width required is 7.5 m.

The 4 central stairs each have a clear width of 1.7m and the eastern end stair has a clear width of

1.2m giving a total clear width of 8m.

Therefore the current design stairs have sufficient clear width for the number of occupants.

SITE SECURITY AND EVACUATION PRINCIPLES

As part of the management of the school, an evacuation plan will be developed which is expected

to include:

- Staff and teachers informed of an event that requires evacuation.

- Evacuation of the classes to a safe location at a distance away from the building, that is

accessible from a public roadway.

- The evacuation would be undertaken by staff (Teachers)

- In a school normally students are orderly evacuated by teachers and staff to the sports field

as part of the evacuation process.

Within the proposed design the school perimeter will be fenced with a security fence to 2100mm

high and gates located at pedestrian and vehicle entry points.

The gates will have security control with the gates being closed and locked during school hours.

There are a total of 10 gates to the perimeter of the site, of these the following gates are the main

entry and exit gates that will be provided with secure access and egress.

The proposed works also includes internal fences to provide separation between vehicle and

student areas, with gates that will not be locked. To ensure free egress from the building.

All staff will be provided with security swipe access through these gates, which will ensure that

they can exit the site at all times;

PART D3.1 – GENERAL ACCESS REQUIREMENTS

Under the BCA requirements in Part D3.1, an access pathway is required to areas depending upon

the usage of the area as indicated in the table below, except as permitted by Clause D3.4.

Applying this requirement to the proposed works, access is required to all areas as indicated in the

following table.

PART D3.2 GENERAL BUILDING ACCESS REQUIREMENTS

Part D3.2 of the BCA requires an accessible pathway to be provided from the main street frontage,

at least 50% of all entries and the accessible parking space to the building.

Within the proposed design there are 4 potential pedestrian entries to the site, being:

• From the Hazlett Street frontage via the main building entry.

• From Hazlett street frontage and through the north east façade entry.

• From Wicham Place to the north west, which is an entry but will not be encouraged to be

used.

• From the south western corner of the site, which links to a proposed future roadway.

Of these entries to the site three of them have an accessible pathway to the building. The exception

being the entry from Wickham Place.



As part of the development new carparking, including 2 accessible parking spaces will be

constructed adjacent to the main building entry and an accessible pathway will be provided from

the parking space to the main entry.

Based on this the main entry to the site and at least 50% of all entries area accessible and therefore

the design meets the Deemed to Satisfy requirements for the provision of an accessible pathway to

the building under part D3.2.

PART D3.3 PARTS OF BUILDING TO BE ACCESSIBLE.

Under part D3.2 of the BCA, access is required to all areas normally used by the occupants and

includes areas such as toilet facilities, meeting rooms and kitchens etc.

Access paths, door widths and door clearances are to comply with AS1428.1 - 2009

The current design for the room layouts indicate that access will be provided to all areas on all levels

using the lifts indicated.

The following criteria from As1428.1 sets out the requirements for providing access, that should be

included within the detailed design:

• All doorways should be minimum 850mm clear (requires min. 920mm leaf doors)

• Provide side clearances to doors as per Figure 31 of AS1428.1 ( refer below.)

• Provide lobbies with min 1450mm clear lengths to enable usability. (refer below)



LIFT

A lift is included within the design, to provide access between the various levels and floors of the

Building, to meet the DTS requirements for an accessible pathway through the building.

The lift will travel less than 12m, therefore the lift car floor dimensions will need to be as set out in

the following table.

ACCESSIBLE TOILET FACILITIES

The design includes new accessible facilities provided adjacent to the location of other toilet

facilities in each area and the documented detailed design of the facilities are to meet the planning

requirements of AS1428.1-2009. Refer to Section 2.7.2 of this report for details.

PART D3.5 CAR PARKING

Where car parking is provided part D3.5 of the BCA requires a minimum of 1 accessible space per

50 car parking spaces is to be provided.

The current design includes the provision of 12 parking spaces to the southern side of the building

adjacent to the entry, two of which are accessible parking spaces with a central circulation space.

The current design of the parking spaces in size and configuration meet the Australian Standard

requirements.

Therefore the design meets the requirements for the provision of accessible parking spaces.

PART D3.6 IDENTIFICATION OF ACCESSIBLE FACILITIES, SERVICE AND FEATURES

Part D3.6 requires signage complying with Specification D3.6 to be included within the building in, a

number of locations to identify the following:

• All sanitary facilities

• Identification of exit ( where exit signage is included.)

• Path of travel to the Lift if not evident from the main entry.

Signage is to be included as part of the detailed design.

PART D3.7 HEARING AUGMENTATION

Part D3.7 requires that where an amplification system within a meeting room of more than 100m2

a hearing augmentation system is to be installed.

Within the design if sound amplification systems is included then a hearing augmentation system

will be required.

PART D 3.8 TACTILE GROUND SURFACE INDICATORS

Part D3.8 of the BCA requires that tactile ground surface indicators (TGSI’s) be installed at the top

and bottom of open stairs and ramps to warn occupants of the associated hazard, where the area

is to be accessible.

The detailed documented design is to include tactile indicators to the top and bottom of all stairs

and ramps to meet the DTS requirements.

PART D3.9 WHEELCHAIR SEATING SPACES IN CLASS 9B ASSEMBLY BUILDINGS

Part D3.9 and table D3.9 sets out the requirements for the provision of seating spaces for wheel

chairs where fixed seating is provided and requires that where there is up to 150 fixed seats at least

3 spaces for wheel chairs is provided.

Within the design there is amphitheater seating provided in the following locations:

2.5.16.1 AMPHITHEATRE ADJACENT TO STAIR 6.

The Amphitheatre area includes stepped tiered floor which is designed to be seating for up to

approximately 100 students.

The area is provided with a space to the end that can accommodate two wheelchairs adjacent to

the seating. Table D3.9 would require 3 wheel chair seating spaces in this area.

The current design includes space for potentially 2 wheel chairs and an additional space is required

as indicated in the figure below.

Figure 7- Seating Area

2.5.16.1 AMPHITHEATRE ADJACENT TO STAIR 9.

The Amphitheatre area includes stepped tiered floor which is designed to be seating for up to

approximately 60 students.

Table D3.9 would require 3 wheel chair seating spaces in this area.

The area is provided with a space at one end that can accommodate two wheelchairs adjacent to

the seating and a space at the other end for one wheel chair to meet the requirements for wheelchair

seating.

Space for 2 wheel

chairs

Space for 1 extra

wheel chair is required



Figure 8- Seating Area

2.5.16.1 SEATING ADJACENT TO STAIR 5.

The space adjacent to stair 5 is designed for casual informal student seating.

The area is provided with a space at one end that could accommodate two wheelchairs adjacent to

the seating. However Table D3.9 would required three seating spaces.

In light of the small area of seating and the informal nature of the seating it is considered that the

current design would be acceptable.

This is to be addressed as a Performance Solution to show that the design meets the intent of

Associated Performance Solution or the design is to be modified to include additional seating

spaces..

2.6 PART E – ESSENTIAL FIRE SAFETY MEASURES.

The Essential Fire Safety Measures to be installed in the building are based on the type size and

scale of the building,

The following table sets out the essential fire safety measures that are to be installed.

It is noted that an exemption exists for classrooms to not be provided with fire hose reel coverage,

therefore the proposed design includes a fire hose reel to the ground floor level of the relocated

modular building only.

The Current Design includes the following essential fire safety measures:

• Fire Hydrant coverage to all floor areas to As2419.1.

• Fire hose reel coverage to the administration areas, library and hall but not to the

classrooms as permitted under Clause E1.4 (iv).

• Emergency Lighting and illuminated Exit signage.

Within the Design, it is noted that a mechanical exhaust system is to be installed to provide cross

ventilation to the classrooms and ventilation to the withdrawal rooms. The system ductwork will

connect a number of rooms together .

The system would not be classified as a minor exhaust system under Clause 5 of AS 1668.1 or a

Kitchen exhaust system under Clause 6 of AS1668.1 and therefore a detection system in line with

Clause 5 of NSW BCA E2.2a would be required to initiate shutdown of the exhaust system in the

event of a fire to prevent smoke transfer between rooms.

Clause 5 c (ii) of NSW BCA E2.2a does not require the system to activate an occupant warning

system.

Part F1 of the BCA requires that the external façade of the building be designed to maintain

weatherproofing and prevent water ingress to the building.

This has been included in the detailed design documentation.

PART F2 – SANITARY AND OTHER FACILITIES

Part F2 of the BCA sets out the required number of toilets to be provided based on the number of

people that will be catered for within the building and the use of the building.

For a school building the following criteria is required.

- Separate facilities are to be provided for Students and Staff.

- Separate Male and Female facilites are to be provided

- At least one ambulatory male and female cubicles are to be included in each group of facilities.

The total facilities to be provided across the school campus are to be as set out in the following

From the table above it can be seen that the facilites meet this requirement except for the Accessible

student facilities on Level 2 where Access Toilet L2.07 should be changed to being right handed.

From the table above the number of facilities proided is sufficient for the total number of students

and staff proposed in the building.

2.8 PART F3 – ROOM SIZES

Part F3 of the BCA requires the following ceiling heights in certain rooms within a building:

• Airlocks bathrooms storerooms, tea prep areas and the like – 2.1m

• General area – 2.4m

• Above stairways, measured vertical above the nosing – 2m

• Auditoriums and corridors leading to auditoriums that accommodate more than 100

occupants – 2.7m

The design appears to be able to meet these requirements.

2.9 PART F4 – LIGHT & VENTILATION

2.9.1.1 LIGHTING

Lighting is required to all rooms in the building. This can be achieved by either natural daylight, or

other lighting methods. If daylight is used the area of windows is to be at least 10% of the floor area.

Therefore an external window and the size of the windows are to be at least 10% of the floor area of

the room served to meet the requirements of Clause F4.1

All classrooms are required to be provided with natural daylight via a window. The current design

includes external windows to all classrooms with an area of approximately 9m2 per classroom,

which is more than 10% of the typical classroom size of 63m2 and therefore meets the

requirements.

2.9.1.2 VENTILATION

Ventilation is to be provided to all rooms and this can be achieved by either natural ventilation

through operable windows and doors or by mechanical ventilation to AS1668. If natural ventilation

is to be used then the area of the operable windows should be at least 10% of the floor area of the

room.

PART F5 – SOUND INSULATION

The BCA under Part F5 requires sound insulation of walls and floors that separate Sole Occupancy

Units from other adjacent SOU’s or other spaces within the building. Particularly in Class 2 & 3

buildings.

This does not apply to the proposed works which is of class 9b use.

2.10 PART H – SPECIAL USE BUILDINGS

Part H of the BCA applies to buildings which are used as Entertainment Venues and therefore does

not apply to the proposed works.

2.11 PART J – ENERGY EFFICIENCY

Energy efficiency requirements of the BCA generally apply to part of a building that are air

conditioned, which are not of Class 2 usage. NSW Basix legislation applies to the Residential Class

2 buildings

PART J1 – BUILDING FABRIC

The proposed building is class 9b use located in climate zone 7 and will require the following thermal

performance of the various parts.



PART J1.2 THERMAL CONSTRUCTION

The installation of materials associated with the thermal performance of the building are to be in

accordance with AS 4859.1.

Assuming that the roofing material colour is a mid to dark colour (Solar Absorbance of 0.6 or more)

Then the following table shows the insulation requirements for the roof and ceiling combination for

the various zones from Table J1.3a. These values assume that more than 99% of the roof area is

insulated.

Table 5

PART J1.3 ROOF AND CEILING INSULATION

The combined roof and ceiling insulation is to give a total R value of R3.2 or more. The insulation is

to be provided as a combination of roof and ceiling insulation.

PART J1.4 ROOF LIGHTS

Part J1.4 of the BCA sets out specific requirements for roof lights when the area exceeds 1.5% of

the floor area and permits skylights to be up to 5% of the floor area.

Where roof lights or skylights are included their thermal performance will need to achieve minimum

thermal performance criteria dependent upon the proportional area of the skylight to the space

served.

Curranty the design does not include skylights.

PART J1.5 WALLS

External walls are required to achieve a minimum Total R-Value of at least R2.8.

The insulation is to be included in the detailed design specification.

PART J1.6 FLOORS

Specific thermal performance requirements are set out in Part J1.6 of the BCA for suspended floors

with unenclosed perimeters on the lower levels.

If there are any new suspended floors that are open below, they will be required to be insulated to

prevent heat loss.

The current design does not include insulation to the underside of the upper floor floor slab under

classroom areas. This is a technical non-compliance that is planned to be included as part of the

Thermal performance assessment to the undertaken using the JV3 process.

PART J2 – EXTERNAL GLAZING

2.11.7.1 PART J2.4 GLAZING METHOD 2

Compliance with Part J2.4 is achieved by analysis of the areas of the external façade and the

proportional areas of the external glazing.

The analysis is undertaken during the detailed design to show compliance based on the building

façade elements and will be required as part of the Construction Certificate documentation.
