The Design of Car Parking Spaces Presentation 5: Mechanical Parking Prepared July 2012 DRAFT ONLY FOR REVIEW Note: This presentation is just a basic overview and does not include all information relevant to off- street vehicle facilities. Advice should always be sought from a qualified consultant. All figures/tables sourced from Standards Australia, Victoria’s Planning Scheme and other sources are for pictorial purposes only. It is expected that the user will have access to a legitimate version of each guideline. This presentation should be read in conjunction with the above mentioned guidelines or any other relevant specification. This is not a guideline. � 1
Conventional Spaces • Must meet the dimensional requirements of Table 2 to Clause 52.06 • Must meet the clearance requirements of Diagram 1 to Clause 52.06 • Typically this would be a 2.6m wide, by 4.9m long, 6.4m accessway with 300mm clearance to fixed objects within the door opening region (note: entry splays to columns are 250mm x 100mm minimum) Presentation 5: Mechanical Parking � 2
Conventional Spaces • Note that Australian Standard AS/NZS 2890.1:2004 (AS) does have different spaces sizes and clearances; however, Clause 52.06 sizes should be used in preference • Notwithstanding the above, AS sizes can reduce to 2.4m wide, 5.4m long and 5.8m aisle with 300mm clearance to fixed objects in door opening regions for resident and employee use only (note: minimum entry splays to columns are 750mm x 300mm) Presentation 5: Mechanical Parking � 3
Design Vehicle • B85 vehicle: 4.91m long x 1.87m wide (AS) for access to car bays • B99 vehicle: 5.2m long x 1.94m wide (AS) for access to roadways, accessways etc. • Height clearance of 2.1 metres (Clause 52.06) excluding disabled Presentation 5: Mechanical Parking � 4

Vehicle Accessories • Bull/nudge bars • Tow bars • Roof rails/racks • Aerials radio/sat nav Presentation 5: Mechanical Parking � 7
Boot Access • Access to rear boots on hatch back style vehicles requires additional headroom • The Honda Civic and Subaru Outback shown measured 1.93m and 2.0m with boot lid raised Presentation 5: Mechanical Parking � 8
Driver/Passenger • The height and width of a driver/passenger can vary substantially • The average height of a male in Australia according to ABS is 176cm; however, note that there are taller people as this is just the average, not the 85th percentile • The average waist size of a male in Australia according to ABS is 96cm; however, note that there are people with wider waists • There is also people with walking difficulties ABS data sourced from www.abs.gov.au/ausstats/abs@.nsf/Lookup/4841.0Chapter22011 Presentation 5: Mechanical Parking � 9
Type 1 - Dependant • Require entry level vehicles to exit before upper/lower level vehicles can enter/exit (i.e. tandem) • Only a consideration for the same residence if more than one space is required or the same office tendency • Usually available in single and double platforms Images sourced from multiparking.com.au Presentation 5: Mechanical Parking � 10
Type 2 - Independent • All spaces accessible independent of each other • Move up and down only • Usually available in single and double width platforms Images sourced from multiparking.com.au Presentation 5: Mechanical Parking � 11
Type 3 - Independent • All spaces accessible independent of each other • Move up/down and left/right (usually at-least 1 blank space for operation) • Longer unit due to left/right action • Requires stacker doors (this is additional to stacker unit length) • Columns must be external of pit due to left/right action • Usually only single width platforms Images sourced from multiparking.com.au Presentation 5: Mechanical Parking � 12
Stacker Considerations • Side rails between stacker platforms that may prevent vehicle overhang as well as restrict driver/passenger walking space • Structural intrusions that may not meet door clearance or entry splay requirements • Are usually available in models smaller than permitted for conventional car spaces • They must be able to store the entire length of a vehicle with clearance as they go up/down and in some case left/right (note: conventional Clause 52.06 car space lengths require the B85/B99 vehicle to overhang) Presentation 5: Mechanical Parking � 13
Stacker Versatility • Is there opportunity to swap spaces with other tenants/owners? (note: if there is a mix of taller and shorter units, there maybe opportunity to swap units in an informal manner between tenants to cater for differing vehicle sizes/shapes and person heights) • Where is the use located? (note: just because they live/work near inner CBD suburbs does not mean the user won't own a Porsche Cayenne 4WD; however, options such as bull bars, tow bars, roof racks may not be expected) • Is the end user likely to be an owner or a tenant (note: apartment/ office developments are often renters/employees, and users are likely to change regularly, so catering for differing vehicle sizes may be an important consideration) Presentation 5: Mechanical Parking � 14
Statutory Requirements Clause 52.06 • At least 25 percent to be 1.8 metres height • Not for visitors (unless valet parking) • To be designed to the satisfaction of the responsible authority AS Requirements • To be designed in accordance with this standard (note: space dimensions should not be less than Clause 52.06) • Ensure queues do not extend beyond the property boundary Presentation 5: Mechanical Parking � 15
Stacker Layout • Mechanical Parking is mentioned within the Victorian Planning Scheme and Australian Standards • Therefore the responsible authority cannot reasonably refuse them and should accept at least 25 percent of stacker units with a height of 1.8m • However, the design and layout has to be to the satisfaction of the relevant authority, so this is where it is important to get the design correct early on in the process as this could dramatically alter the design of the development Presentation 5: Mechanical Parking � 16
Stacker Height What is a reasonable height? • All at 2.1 metres would be ideal as this would provide the same height clearance as conventional bays • However, since Clause 52.06 does mention 25 percent at 1.8 metres, then this is an indication that a departure from conventional 2.1 metre heights could be a consideration Presentation 5: Mechanical Parking � 17
Stacker Height Since 25 percent can be at 1.8 metres does that mean the rest need to be 2.1 metres? • Some responsible authorities may interpret it that way, but then some consultants may interpret it as the rest can be lower than 1.8 metres • The rest at below 1.8 metres is probably unreasonable. The rest at 2.1 metres lines it up with conventional bays; however, may not always be possible or necessary. Presentation 5: Mechanical Parking � 18
Stacker Height What is acceptable to the Responsible Authority? • It would be reasonable to assume the Responsible Authority would accept 25 percent at 1.8 metres and the rest at 2.1 metres height • Any departure from the above, would require sufficient justification of the proposed layout in an effort to convince the Responsible Authority • Therefore, always seek to provide the maximum height possible; however, exceptions may be possible Presentation 5: Mechanical Parking � 19
