2.3 PARKING PROVISIONS No additional parking provisions will be added to the campus as part of this project.
The current approximate student population on campus in any one day is between 600-800 students with many utilising public transport.
The new Light Automotive facility has capacity to accommodate a maximum of 250 students and 10 additional staff. It has been reviewed and anticipated that this increase in campus population can be sufficiently managed within the existing parking provisions and the regular public transport network already servicing the academic precinct.
Existing parking accessed via Lakeside Drive (222 bays)
• 185 Students bays • 3 ACROD bays • 6 Visitors bays • 6 Motorcycle bays • 21 Staff bays • 1 Deliveries bay
Existing parking accessed via Kendrew Crescent (371 bays)
• 237 Students bays • 1 ACROD bay • 34 Visitors bays • 7 Motorcycle bays • 92 Staff bays
This academic precinct is well serviced by regular public transport namely Joondalup train station 1km walk to the northwest and bus transport immediately available at Lakeside drive (Red CAT) and Grand Boulevard (Blue CAT, 390, 391, 460, 461, 466, 467, 468, 470, 471, 473 and 474) some 450m to the northwest
3.0 SPP 7.0 – DESIGN OF THE BUILT ENVIRONMENT The State Planning Policy 7.0: Design of the Built Environment sets out the objectives, measures, principles and processes which apply to the design and assessment of built environmental proposals through the planning system.
The SPP 7.0 has guided the design team, PCG and reviewers throughout the design development phase of the North Metro TAFE Auto Trades Facility. A good TAFE design outcome aims to improve the urban environment of the campus, benefit the local Joondalup community and foster a positive impact on the North Metro TAFE student/ staff experience. Refer to the below Design Statement which outlines a detailed explanation of how the proposal addresses the SPP 7.0 Schedule 1 – Design Principles .
Page 5 of 34 DESIGN STATEMENT
3.1 CONTEXT & CHARACTER The master planning of the new automotive building has evolved from a detailed analysis of the available site and existing built forms and responded accordingly to the following determinants:
• The opportunity to respond to the curved geometry and built form of Block D (client Services/ Library/Café) by mirroring the curvilinear plan along the centreline of A Block to create a new central ‘social heart’ to the campus. It is envisaged that this new ‘Student Court’ will provide a Yellagonga meeting place, improved connections for students to Client Services, Library and improved alfresco seating areas for the existing Café. • The combination of D Block and the New Light Automotive Training facility will frame up the Student Court to improve the definition of the existing amphitheatre and provide a suitable venue for events and whole of campus meetings and generally encourage, integration and collaboration. • The geometry of the new building respects that of the existing carpark to the East which mitigates any major reconfiguration of the carpark layout. • Direct access from the driveway into the new automotive workshop for equipment/ vehicles has been logically enabled. • The building footprint extent gently retracts at points to carefully retain and conserve existing Tuart trees on site. By retaining these trees there will also be a strong visual link back to nature from the interior learning spaces. • To enable the desired building layout, an existing horticulture building and creche will be relocated with the horticulture facilities strategically relocated adjacent to the existing greenhouse and planting areas north of block D. The relocation of these existing facilities must occur before construction can commence on the main building. • The main building layout responds well to these adjacencies by locating horticulture, laboratories etc. within proximity to the existing and ‘relocated’ detached horticulture facilities.
3.2 LANDSCAPE QUALITY Refer to Appendix H for the Landscape Architects Design drawings and report prepared by Ecoscpae.
The philosophy for the landscape design of the North Metropolitan TAFE – Light Automotive & Horticulture Training Centre is to provide a safe, accessible and welcoming landscape for students and staff. The focus is providing a landscape that serves two main purposes: 1. An easily traversable space for moving between the Light Automotive & Horticulture Training Centre and surrounding campus. 2. A gathering space for staff and students, catering to varying sizes from small gatherings to larger-scale events. A key objective in the design of the landscape is the minimisation of on-going maintenance. Appropriate species selection and placement within the landscape will reduce the ongoing irrigation requirements of the site and in some areas may eliminate the need for irrigation entirely once planting has become established. Trees located away from building edges will reduce maintenance while still providing solar shading to the western façade of the Light Automotive & Horticulture Training Centre.
Hunt Architects have shared the proposed landscape design with the City of Joondalup to ensure their acceptance of the proposal.

3.3 BUILT FORM & SCALE The proposed building’s geometry and materiality both combine to reflect a ‘state of the art’ imagery reflective of the building functionality as a training environment in advanced automotive technology e.g. Electric and hydrogen powered vehicles.
Panelised lightweight metallic cladding coupled with complementary high-performance glazing is reminiscent of automotive design. Simplicity has been an intentional design focus to create a timeless outcome through the avoidance of ‘façade trends.’ The buildings overall presentation is dynamic and contemporary yet honours its obligation to fit within the site and existing building context.
The building scale is in keeping with the context however form and materiality represent an intentional departure from the existing TAFE Campus building fabric. Careful consideration has been given to ensure the external cladding finish and built form scale provides visual stimulation when arriving at the Lakeside Drive campus entry.
Page 7 of 34 Internally the learning environment will naturally encourage and underpin collaboration, lending themselves to innovative outcomes for students and Industry. Internal space shall reflect the training delivered therein, resilient finishing, efficient layouts and equipment carefully crafted to seamlessly demonstrate the embodiment of a white lab coat technology driven environment. Good use of natural light and outlook into garden/ amphitheatre space wherever possible will aid the amenity of the learning environment.
It is anticipated the building will be a two (2) storey structure in the order of 7 to 8m high. The Automotive workshop has been sized to allow a 5m pitching point on the east to accommodate 2m vehicles on hoists. Vehicle access on the north has been sized so that small to medium sized heavy vehicles can access the workshop. This has been included to allow flexibility in future trends given that the first take up of Hydrogen Fuel Cells is likely to be long-haul trucks.
The pitched roof line is in keeping with the existing D block form and allows for adequate above ceiling service distribution.
The result of the design solution is illustrated in the below coloured 3D perspectives and Elevations.

Page 9 of 34 3.4 FUNCTIONALITY & BUILD QUALITY
The new Automotive Training Facility will be located on the North Metropolitan TAFE Joondalup Campus, Kendrew Crescent, Joondalup, comprising the construction of one new building abutting a landscaped quadrangle and existing carpark.
The building functional planning solutions has evolved into a well-ordered arrangement of specialised training rooms over two levels anchored by the main double volume foyer space. Training rooms to the north of the foyer showcase automotive training which will be readily viewed through glazed walls both at ground and first floor level. South of the foyer are located a Live works “Customer Service” counter; an Environmental Diversity lab and the Lab which recently moved to the southern portion because industry representative considered it essential that the Collision Avoidance Technology Lab be directly accessed off the Automotive Workshop.
• Automotive Workshop: 600sqm in area with vehicular access from the north via a large roller door. The workshop is sized to suit three or four 2 post hoists and a single 4 post hoist each with adequate surrounding space for students to gather. It is envisaged that each hoist will be equipped with compressed air reticulation and an overhead Nederman exhaust reels to address combustion engine fume exhaust requirements. Overall, the workshop will receive evaporative cooling for ventilation and solar tube skylights will supplement daytime lighting provisions. The workshop floor will be cast concrete without falls so as to avoid risks of heavy gas accumulation if LPG provisions are included. A Diagnostics Lab and Collision Avoidance Technology Lab have been added and positioned to provide vehicular access directly from the main workshop. • Ground floor Technical Labs will be fitted with test benches and serviced with power supplies ranging from three phase, single phase outlets to low voltage as required to suit course delivery requirements. • Foyer: 200sqm in area will be a truly multifunctional space that can be configured as a student training space, exhibition/graduation space, and showroom to showcase the latest innovations in the automotive industry. • The Building Amenities are served by toilets and end of trip shower facilities on the ground floor with further toilet facilities at first floor level. No café or student tea preparation facilities are provided given the proximity to the D block café. • Vertical transportation is provided via a single lift and generous stair which afford access from the foyer to the first-floor level.
Page 10 of 34 • The First floor Level is devoted to computer training Labs to support Data Analytics, a robotics lab, Staff accommodation and a conference room. • It is anticipated that the Workshop will rely on Evaporative cooling for its air conditioning and these units will be located at Roof Level whilst the remainder of occupied spaces will be conditioned using ducted reverse cycle units with ceiling void Fan Coil Units and a Condensing unit plant room located either at first floor level (current plan) or at roof level (budget permitting).
Refer to Appendix E for detailed Architectural drawings.

Refer to Appendix I for the detailed Greenstar Scorecard.
3.6 AMENITY The new training facility will be equipped with good levels of internal amenity for a range of class/ training usages, delivering appropriate levels of acoustic protection and visual privacy, adequate storage and equitable access for all.
The project team acknowledge the importance of Disability access and inclusion planning. In addition to adhering to all Australian Standards and Building Code, the design team will ensure access and wayfinding is inclusive to all abilities.
The well-designed external space provides a welcoming, universally accessible and comfortable entry experience for all. Effective shading will encourage the use of the central quadrangle and the strategic positioning of the new facility will provide protection the central court from unwanted weather conditions.
Page 13 of 34 It is anticipated that high performance reflective glass will be incorporated to provide good daylight levels, natural ventilation, outlook and amenity. Windows will be ‘front glazed’ to mimic the seamless glazing/body panels of the modern sedan car. The façade design deploys high-performance glazing to limit solar heat penetration.
3.7 LEGIBILITY There are various types and styles of wayfinding signs on the campus currently that have been added in an adhoc manner.
Wayfinding signage will be provided to the facility main entry point, interiors and to indicate key adjacent buildings/ carpark beyond. The design of the external wayfinding signs is proposed to be a pylon/ monolith type; ACM cladded to aluminium frame, LED illuminated with router cut push through acrylic letters.
The external main entry sign to the facility will be back lit. External ‘totem style’ and wall mounted signage will be added to aid wayfinding to the new facility and broader campus beyond.
Internal direction signs will generally be ceiling hung Laminex panel type with directly digitally printed graphics. Internal door signs will be matt vinyl text direct fixed to doors. In principle, rooms that will be used by the students and staff will be named. Strong unobstructed sightlines will aid safety and general operations of the automotive training facility.
Statutory signs will be provided as per the BCA or Australian Standards requirements.
3.8 SAFETY The new facility optimises safety and security, minimising the risk of student/ staff injury and anti-social behaviour. Security and safety is promoted via strong sightlines throughout the facility and well light, secure access points that are easily maintained and respond to the function of the facility. The central quadrangle landscape design will encourage student/ staff gathering and subsequently foster opportunities for passive surveillance of these public/ communal areas.
Page 14 of 34 Optimal safety and security between the facility and adjacent carpark and quadrangle have been carefully considered. External lighting levels have been designed to promote the safe movement of staff/ students to and from the facility, whilst aiding early hour waste collection or deliveries.
3.9 COMMUNITY The new facility design responds to the curved geometry and built form of the existing Block D (client Services/ Library/Café) by mirroring the curvilinear plan along the centreline of A Block to create a new central ‘social heart’ to the campus. It is envisaged that this new ‘Student Court’ will provide a Yellagonga meeting place, improved connections for students to Client Services, Library and improved alfresco seating areas for the existing Café.
The new central ‘social heart’ of the campus will foster social activity in all inclusive, equitable manner and considers how activities inside the adjacent buildings can bring life and activity to public spaces.

Page 16 of 34 4.0 AUTHORITY CONSULTATION A consultative process has been completed with City of Joondalup where our consultant team has investigated the site constraints and planning obligations applicable to the site.
Advice received to date:
The City of Joondalup Planning Team provided the following preliminary advice: Proposal generally meets the requirements of the JACP however the following questions have been raised;
• Car parking is identified as subject to negotiation with the City. I have liaised with the City’s engineers however not received any feedback. Any application would also need to identify impacts on the existing parking (i.e. how many bays are being lost to provide access to the workshop?). • Development in Bushfire Prone area and as such BAL and BMP would be required and need to be referred to DFES due to it being a ‘vulnerable land use’. • Given the type of development this would be required to go to our Design Review Panel (DRP) which meets once a month. Commentary from this panel is something which is required to be considered in the planning assessment. • Further information would be required about service areas/bin collection areas along with how these will be services. Information on deliveries (requirement for and associated timing). • Further information would be required regarding bicycle parking through the TAFE site. This relates to the number of students, therefore also would require the additional number of students this development will cater for compared to the existing development. • The proposal is 9.9m and under the minimum height of 13.5m as identified in the JACP. This is generally fine subject to other urban design implications that may be raised at the DRP meeting.
The City of Joondalup Environmental Team provided the following preliminary advice: The following are suggestions for considerations to minimise environmental impacts:
• The building envelope design should consider retention of native vegetation on site where possible, in particular the large Tuart and Marri trees. • Consideration should be given to whether any threatened ecological communities or priority ecological communities occur on site, taking into account the surrounding bushland areas. • Consideration should be given to whether any priority or conservation significant flora species occur on site and if they can be retained. • A black cockatoo habitat assessment may be required in accordance with the Environment Protection and Biodiversity Conservation Act 1999 referral guideline. • A native vegetation clearing permit may be required under the Environmental Protection Act 1986. • Consulting with the recently formed Friends of Central Park Bushland, led by Brooke Fellows who is a staff member at North Metro TAFE. The Friends Group might be interested to provide input regarding environmental considerations. • Avoid impacts to groundwater as the proposed site falls within a Priority 3 Public Drinking Water Source Area. • Any on ground works to incorporate pathogen hygiene principles to avoid the introduction or spread of pathogens. • Any landscaping to incorporate endemic native species.
Formal advice from DOF Deputy Director General regarding DAWE referral:
I approve proceeding to tender without referral to the Federal Dept of Agriculture, Water and Environments (DEWA), based on the advice:
Page 17 of 34 • We have taken every mitigation possible to protect the 3 live tuart trees and will ensure their protection throughout construction;
• There is no other design option to protect all 4 of the live trees; • The only way to remove the risk is to lodge an application, which based on the advice of the planning team is not required. Therefore this seems to be an unnecessary step which will only cause delay; and
• The Planning team’s advice has been confirmed in conversation with DEWA representatives.
Building Setbacks 1. The new building has a setback dimension of 3m from the Eastern existing TAFE carpark and 60m from Lakeside Drive. The proposed building is situated well within the site boundary.
Building Height 1. The building has a maximum height of 9.3m (RL58.3) from ground floor level. This is in alignment with the existing TAFE campus built form heights.
5.0 PROJECT PROGRAM • DA application: April 2021 • Completion of working drawings to 95%: June 2021 • Completion of the Bill of Quantities: Mid July 2021 • Completion of Client review: Mid -Late July 2021 • Tender date: Early August 2021 • Tender acceptance: 1st week November 2021 • Practical Completion (excluding contingency): Early November 2022 • Occupancy Certificate: Late November 2022 • TAFE Occupation familiarisation: December 2022
6.0 WASTE MANAGMENT Waste management during construction:
The appointed contractor will be required to submit a waste management plan to the satisfaction of City of Joondalup before work commences on site. This requirement will form part of the conditions of contract.
Waste management post occupation:
The campus is currently serviced by a private waste removal company that disposes of rubbish on arranged schedule. This occurs typically on a fortnightly basis. The building works include the construction of a dedicated 10 sqm external bin enclosure capable of housing 4-5 medium bins (refer Ground Floor plan). It is anticipated that waste disposal may increase to a weekly cycle subject to demand which will be reviewed once the new facility is operational.
The existing dedicated waste/ service vehicle bay will assist with efficient and safe waste removal and deliveries.
Page 18 of 34 7.0 TOILET AMENITY CALCULATIONS Toilet numbers have been calculated based on a maximum student population of 250 students. To date it is unclear how many staff will be resident in the building so we will make provision for 1 staff UAT + 1 separate unisex toilet facility

6.0 SITE CONSIDERATIONS
6.1 ENVIRONMENTAL REPORT Hunt Architects engaged the services of Focused Vision Consulting Pty Ltd (FVC) to undertake an inspection of the proposed development areas (study area), which focused on flora, vegetation, fauna and habitat values. This report comments on the findings of the biological assessment.
The field assessment, incorporating a reconnaissance flora and vegetation survey, fauna habitat mapping and a targeted Black-cockatoo habitat assessment, was carried out by Principal Ecologist, Kellie Bauer-Simpson on 10 March and 14 April 2021. A follow-up tree hollow inspection was carried out by Principal Zoologist, Dr Mike Bamford, on 17 March 2021.
The key findings and conclusions arising from the flora, vegetation, fauna and habitat assessment within the study area are as follows:
• No Threatened flora under the Biodiversity Conservation Act 2016 (BC Act) or under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) were recorded. • One Priority 4 species, Jacksonia sericea was recorded at relevé NMT02R, within vegetation unit EgXp. • The timing of the survey (March and April) was not considered optimal for the identification of flowering flora or annual and ephemeral species and therefore, it is likely that not all species relevant to the study area were recorded. However, this is considered a low risk given the relatively degraded nature of the study area, where key values are considered to have been adequately sampled. • Vegetation unit EgXp is considered to be representative of Commonwealth-listed Tuart woodlands and forests Threatened Ecological Community (TEC) with one patch that meets condition thresholds to be eligible for protection under the EPBC Act.
Page 19 of 34 • Three fauna habitats; Tuart Woodland, Marri Woodland and Isolated Marri were described and mapped across the study area. • The following Black-cockatoo habitats are supported by the study area: o Foraging habitat: . 0.541 ha of ‘moderate to high’ quality foraging habitat for Carnaby’s Black-Cockatoo within the Tuart Woodland and Marri Woodland habitats . 0.217 ha of ‘moderate to high’ quality foraging habitat for Forest Red- tailed Black-Cockatoo within the Marri Woodland habitat . 0.324 ha of ‘moderate’ quality foraging habitat for Forest Red-tailed Black-Cockatoo within the Tuart Woodland habitat . 0.131 ha of ‘moderate’ quality foraging habitat for Carnaby’s and Red- Tailed Black-Cockatoo quality foraging habitat within the Isolated Marri habitat. o Breeding habitat: . One tree with suitable breeding habitat in the form of an artificial nesting hollow (Cockatube) . One tree with hollows, although these were confirmed to be unsuitable for use by breeding Black-cockatoos . Eight trees lacking any hollows, but of suitable trunk diameter, so may provide breeding hollows in the future. o Roosting habitat: . No known or confirmed roosting habitat is supported by the study area, although tall trees within the Tuart Woodland and Marri Woodland habitats could be potentially suitable, although this is considered unlikely.
The following recommendations are suggested in relation to mitigation and offsetting unavoidable impacts to mature Tuart trees that comprise the Tuart woodlands and forests TEC patch and may provide some habitat for Black-cockatoos:
• Engage a qualified arborist to consider: o any ways in which trees that require clearing (particularly the partially dead/stressed tree with hollows) may be able to be translocated o any ways in which trees that are to be retained adjacent to the proposed development can be protected or restored in health (since their health appears to have been compromised by the adjacent existing structures) via: . mulching and watering . pruning of roots and limbs prior to construction to avoid damage to these during construction which could further impact tree health . regular arborist attendance on site through the duration of construction including monthly inspections and ad-hoc necessary actions to ensure the health of the trees.
Refer Appendix F for the full Environmental Report.
6.2 ARBORIST WORKS
Page 20 of 34 An arborist has been formally engaged to carefully prune and prepare the root ball of the protected Tuart species on site ahead of site possession. In addition, they will be tasked with the responsibility to routinely inspect these existing mature tuart trees throughout the build and report on their condition for the duration of the construction program.
6.3 BMP & BAL ASSESSMENT The site for the proposed Auto Trades Facility contains existing buildings that will be demolished to facilitate construction of the new building. An APZ sufficient to achieve BAL-19 has been proposed for the ATF to enable the functional design to achieve compliance with the assessed BAL, as a requirement of the Department of Finance.
The Bushfire Management Plan (BMP) has been prepared by Stratagen to address requirements under Policy Measure 6.5 of State Planning Policy 3.7 Planning in Bushfire-Prone Areas (SPP 3.7; WAPC 2015) and Guidelines for Planning in Bushfire-Prone Areas (the Guidelines; WAPC 2017).
The proposed development is not considered to meet the definition of a vulnerable land use provided in Section 5.5.1 of the Guidelines, as occupants will typically be over the age of 18 (both staff and students) and are expected to have the physical and mental ability required to respond appropriately in a bushfire emergency. In this regard, there are no requirements to be addressed under Policy Measure 6.6 of SPP 3.7. Refer to Appendix J for the detailed BMP & BAL Assessment.
6.4 SITE SURVEY Feature survey for the site, completed by Veris Surveryors, indicates natural falls for the site generally from west to east, towards the lower lake. Several existing Tuart trees are to be protected and maintained as part of the new building design. The ground level at these trees have guided the proposed ground floor level.
The level is mostly lower than the adjacent carpark, varying up to 500mm. Levels will be reviewed to ensure there is no overflow drainage risk from the carpark to the new build. Retaining will be built into the structure.
6.5 GEOTECHNICAL REPORT A geotechnical investigation of the site has been carried out by Golder. The report advises that below ground conditions for the building footprint comprises fill sand (some areas loose) to a depth of approximately 2.2m over natural sands to depth and limestone. The limestone is not expected to be encountered due to depths being as shallow as 4.6m however given the unpredictable nature of limestone, it should not be completely ignored for any deep service or lift pit excavation.
Groundwater and Acid Sulphate Soils (ASS) will not be a concern for the works.
Earthworks will include an allowance for over excavation to improve natural soil density as the investigation indicates low density sands at depth. Compliant compaction must be achieved to a depth of 900mm below footing level.
Following stripping and removal of organic and any deleterious or oversize materials, earthworks generally will be minimal and will involve cut-to-fill of insitu sands to form the site to design levels. Clean sands currently on the site are generally appropriate for use as structural fill. A small quantity of imported fill may be required to form the full site to design levels. Refer to Appendix G for the detailed Civil Report.
Page 21 of 34 6.6 STORMWATER Stormwater drainage will be contained on site in accordance with City of Joondalup requirements. The near- surface sandy soils are conducive to disposal of stormwater drainage via infiltration.
The City of Joondalup criteria is for containment and disposal on site of the 1% AEP storm event (1 in 100 year storm), 24 hour duration.
A portion of the existing western carpark drains to a densely vegetated, small compensating basin located inside the existing entry driveway. This will be modified as part of the driveway modifications. Some of the new driveway will also be piped to this location.
The larger portion of roof drainage is proposed to drain to the eastern side without eaves gutters. Drainage options will be reviewed and coordinated with the architect, landscape architect and hydraulics consultant. Drainage will be disposed at source into the insitu sandy soils with additional drainage in-ground for rarer storm events. A resilient surface will be required to avoid scour. The location of the drainage will need to be carefully selected to avoid retained tree roots and services. It may be required to over excavate within the existing carpark for the cells and make good to pavements to suit the roof fall direction.
Isolated roof drainage areas captured with eaves gutters will be drained by the hydraulic consultant.to meet the criteria of the City. Refer to Appendix G for the detailed Civil Report.
6.7 ELECTRICAL SERVICES Power supply in the vicinity of the new building is inadequate for simple extension. A new Mains Cable will be installed from the existing Site Main Switch Board located west of B block.
6.8 HYDRAULIC SERVICES The campus has an existing network of hydraulic services in close proximity to the new buildings. It is anticipated that these services have the capacity to cater for the additional buildings.
Fire Hydrant pressure tests have been conducted and our consultant has confirmed that the mains pressure is adequate to service the campus without the need for fire pumps and tanks.
Page 22 of 34 7.0 CONCLUSION
7.1 STATUTORY ASSESSMENT The MRS (Clause 30) requires the WAPC to have regard to the following factors when determining a Development Application:
i) The purpose for which the land is zoned or reserved under the Scheme;
The proposed NMT Auto Trades Facility is consistent with the ‘Central City Area’ zone under the MRS.
ii) The orderly and proper planning of the locality; and
The construction of the new NMT Auto Trades Facility building is contained withing the existing TAFE Site boundary and will have negligible impact on the surrounding area.
iii) The preservation of amenities of the locality.
The proposed facility has been designed in a manner that complements and integrates with the existing NMT TAFE campus/ site to minimise impact on the surrounding community. No Development is proposed beyond the existing TAFE site.
