2 1.0 Overview This category of the LIM has been developed to provide guidance for the design and construction of seats. This category addresses the following: Seat design Seat positioning. Important notes: This resource does not try to replicate all of the provisions of Legislation, Australian Standards (AS) and corporate documentation in words and pictures, nor does it seek to define their requirements. It aims to draw attention to the fact that effectively applied technical requirements translate into desirable qualities for end users. Please refer to the relevant authority websites for updated information and current document distribution dates. These documents are subject to amendments from time to time. Product design, manufacture and installation require an appropriately qualified professional to provide site specific solutions. For further guidance see: LIM Preliminaries LIM Picnic Tables and Benches LIM Shelters. Sunshine Coast Open Space Landscape Infrastructure Manual December 2017 Seats 2

3 2.0 Location The Sunshine Coast Environment and Liveability Strategy 2017 currently prescribes that seats may be located in the following open space types, as indicated per table below: Table 1: Type of open space ELS LIM Embellishments Seats Council-wide Recreation parks District Recreation Landscape Sport Trails Environmental reserves Local Civic Amenity reserves Linear parks Landscape corridors Sports grounds Seats Council-wide District Specific purpose Recreation trails Conservation reserves Nature reserves Bushland reserves Natural amenity reserves Coastal reserves Further technical information for Sport, Trails and Environmental reserves will be incorporated at a later date. In the interim, the basic Recreation / Landscape information can be adapted to suit the site specific solution required. Please note The design and construction of coastal and waterways infrastructure is to be consistent with adjacent open space land usage. The design and construction of recreation trails infrastructure is to be consistent with adjacent open space land usage or any endorsed SCC document (e.g. Coastal Pathway Master Plan) It is expected that council s open space documents will be reviewed from time to time and this table may be subject to change.

4 3.0 Performance criteria The following performance criteria must be satisfied in order for the embellishment to provide a best practice solution. Seats must meet the following criteria: comply with relevant legislation, standards and corporate documentation (including positioning and equal access guidance) made from robust materials that are vandal and corrosion resistant (particularly in coastal areas) durable long life span, typical useful life: seating aluminium battens 15 years seating timber battens 15 years. 1 termite and pest resistant designed to bolt down to finished surface low maintenance. 1 Sunshine Coast Council Asset Management Plan 2012, Parks and Gardens Sunshine Coast Open Space Landscape Infrastructure Manual December 2017 Seats 4

5 4.0 Sustainability To attain strategic sustainability the following principles should be considered where suitable: Materials and products Local materials and local products. Material selection should be based on recycled or recyclable material wherever possible. Metals / plastics that can be: recycled at the end of productive life used in a buy back scheme. Finishes / treatments / products that are the least harmful to the environment and park users. Ensure materials are flame retardant and resistant to fire. Consider maintenance, whole of life costing and aesthetic values. Materials which initially cost more can result in reduced future maintenance costs and / or longer useful life. Made from robust materials that are vandal and corrosion resistant (particularly in coastal areas). Install erosion and sediment control products and practices such as mulching to reduce erosion on excavated areas during construction. Tree and vegetation management Protect existing trees by using tree root sensitive design and / or appropriate setbacks to ensure the ongoing provision of shade and amenity. Protect existing trees from damage during project delivery to ensure continued environmental benefits such as oxygen production, temperature control, flood mitigation and stormwater filtration. Plant new trees to provide additional shade in the future as well as successional tree population. Plan to incorporate all relevant design guidelines at the design stage of a project. This will reduce the need for premature vegetation losses as a result of conflict or ongoing costly maintenance to maintain clearances. Plan to select species tolerant to the local conditions at the design phase and choose quality specimens at the project delivery phase to minimise early losses and reduce ongoing maintenance. Ensure new plantings are appropriately setback from infrastructure. This will reduce long-term maintenance requirements and maximise the longevity of plantings. Planning for future works Co-locate similar embellishments to reduce infrastructure such as water use facilities and underground services. Consider climate change impacts on embellishment location and construction. In coastal areas, design should consider rise in sea level predictions and severe storm events. See Sunshine Coast Environment and Liveability Strategy 2017 for further guidance. Positioning should consider flooding, seasonal / ephemeral water bodies and water table changes. As a sustainable approach, install conduits under concrete slabs for future provision where electrical services are planned. Where conduit is installed for future electrical installations, set brass markers to concrete slab edges to indicate the location. 1 Australian Pesticides and Veterinary Medicinces Authority document The Reconsideration of Registrations of Arsenic Timber Treatment Products (CCA and arsenic trioxide) and Their Associated Labels.

9 6.0 Embellishment guidance Best practice for the design, manufacture and installation of seats includes: Seat Design Ergonomic design for comfort. Seats should have backs where the seat is required for rest and relaxation. If a bench seat has a back it must also have armrests (except in table and seat combinations). Orient seats towards a view where possible. To prevent possible trip hazard, seat leg supports should not have a splayed foot design. Consider bariatrics when selecting seat designs. bariatrics is derived from the Greek word baros meaning weight and is defined by the Medical Research Council as morbid obesity, where a person has a body mass index (BMI) of more than 40. select seat designs with wide seat slats to accommodate larger bolts to the frame, for strength and durability. Maintenance Select a seat design with access underneath to allow rubbish removal (this is particularly important for seats that use incorporated battens). Select a seat design which drains free of water. Use anti skate devices in appropriate locations. Materials, fixings and finishes Select bolt down surface mount seats for ease of replacement. Made from robust materials that are vandal and corrosion resistant (particularly in coastal areas): suitable for the coastal corrosive environment suitable for use in the public open space environment. manufactured to engineering specifications (where applicable). Aluminium: Timber: Consider that aluminium seats may become hot in full sun locations. Preferred timber finish is (non-polyurethane) Ultradeck or Lanotec. Painted timber finish preferred for local parks to reduce maintenance or use aluminium. Sunshine Coast Open Space Landscape Infrastructure Manual December 2017 Seats 9

10 7.0 Positioning guidance Best practice guidance for the way embellishments are placed or arranged, includes: Positioning Site location Provide shade by planting trees at the time of installation. Crime Prevention through Environmental Design (CPTED) principles are important for seat location to ensure that users feel safe, with opportunity for casual surveillance. It is not recommended that seats be installed under mature trees as this can damage tree roots. If this is absolutely necessary, do not install on slab, but provide pier and beam footings. Seats should be positioned with respect to sun exposure, with shade trees and shelters sited to ensure seats are protected from the midday and afternoon sun. Avoid locations near hazards, fire and flood prone areas. Anodised aluminium seats can get hot and are best positioned in the shade. If positioning a seat in a sunny location, choose a lighter colour eg. clear anodised. Avoid locating seats near plants with leaves with cutting edges, sharp thorns, spikes, poisonous parts or locating seats under fragile tree limbs or trees prone to limb drop. Seats should be provided near activity areas, such as play spaces, dog off leash parks, exercise stations, skate parks and sports and games, under shade, for parent / caregiver / dog owner supervision (with clear sight lines to play areas) or for spectators. Do not install seats at locations where they may be used for climbing access onto embellishments such as shelters and shade sails. Do not install seats where they may be used for climbing over a fence or wall (such as at fenced play spaces or dog off leash parks). Site setout Seats can be grouped in clusters to provide gathering places for larger groups of users, and with other embellishments to reduce visual clutter and provide cohesion. Excavation for footings should be made by hand or vacuum excavated to avoid tree roots, under the supervision of a qualified arborist. Locate seats with back to solid objects, such as walls, planting, for security, and orient to optimise views. Group embellishments and services together where possible.

12 8.0 Equal access guidance Implement equal access for all users by adopting the following principles: Elements required for equal access Ensure that seat slabs are connected to a continuous accessible path of travel to enable equal access for people who use wheelchairs. Ensure that the path of travel is connected to an accessible car park space. Provide equal access to seats at the recommended mounting and circulation heights to provide access by people who use wheelchairs. Consider bariatrics when selecting seat designs. Bariatrics is derived from the Greek word baros meaning weight and is defined by the Medical Research Council as morbid obesity (where a person has a BMI of more than 40). BMI is calculated by dividing weight in kilograms (kg) by height in metres (m). Select designs with wide seat and table top slats to accommodate larger bolts to the frame, for strength and durability. Install equal access seats in consistent locations for ease of recognition by people with vision impairment. When retro-fitting an accessible seat under an existing shelter, consider the location of the shelter support posts. If there is insufficient circulation space, a new shelter may be required. Avoid finished height difference between a seat concrete slab and adjoining surfaces to prevent trip hazards and to prevent tramlining of wheelchair wheels. Batter down gently to existing ground level. Provide a wheelchair / pram space on at least one side of an equal access seat slab and on both sides where demand exists. Where possible a range of seat heights should be installed Platform seats should be installed at 450mm height from slab. Consider installing some platform seats at 350mm high for children where the seat is close to play areas. Slab to be have a minimum 1.0m clear area around furniture for wheelchair / pram manoeuvrability. Provide at least one seat with a back rest and armrest at each end to assist people of varying abilities. Overall seat height is 750mm - 790mm as per AS Actual manufactured seat heights are generally higher than 790mm. Ensure a minimum 150mm gap from the seat front edge to the seat base or legs underneath to enable ease of standing. Colour Requirements Provide sufficient contrast with the background against which the object is viewed and has a luminance factor of not less than 30%, for ease of identification by people with vision impairment or The selected seat colour may strongly imply a coloured concrete base slab is used. Contrast can be enhanced, by providing a different coloured concrete border around the seat base to improve colour and luminance contrast. Consider designing nodes with a contrasting coloured concrete, or a variation in surface texture, to enable people with a disability to identify the location of embellishments along a pathway. See the following figures for further guidance: Figure 1: Elevation required offset for rising from a seat + seat with armrest dimensions Figure 2: Seat with back, armrests and wheelchair / pram space Figure 3: Examples contrasting colour concrete and seating Figure 4: Plan wheelchair / pram space adjacent to seat. Install seats at a minimum 500mm offset from the edge of a pathway to a seated person, to provide safe clearance for pedestrians and cyclists.
