Embellishments should be designed/selected and installed as follows:
Fit for purpose, appropriately positioned and accessible.
Durable, robust and safe (suitable for corrosive environments).
Vandal resistant with parts that are easily replaceable.
Easy to maintain (with appropriate warranty and workmanship).
Comply with relevant standards, legislation, corporate documents and approvals
Planning, design and positioning
Geotechnical investigation is required to determine foundation conditions
Link boardwalks and viewing platforms to a universal access pathway where possible
Select a boardwalk to protect an environmentally sensitive site or to bridge across existing tree root systems
Design specifications – Australian Standards and National Construction Code (NCC)
(A) Consider a shelter over viewing platforms for shade. See LIM Shelters
Select design loads to accommodate crowd loading, site specific maintenance vehicle access to viewing platforms and decks, handrail and balustrade, future additions such as lighting
Embellishments must not pose a hazard to the public e.g. entrapment or encourage climbing. Maintain pedestrian and cyclist clearances
Safety in Design requirements must be met
Select and specify a timber species which is tough, stable, durable and resistant to UV degradation. Consider non-timber materials
Consider a 5% over-order of decking materials for future maintenance purposes.
(B) Boardwalk and viewing platform requirements
Substructure members – footings, piers, pier cap, bearer, joists, boardwalk to pathway transition
Superstructure members – decking, barrier, railing, kerbs, seats, shelters
Elevated boardwalk requires handrail and balustrade (depends on calculated fall height)
Low/on ground boardwalk requires kerbs both sides to prevent wheeled devices from running off the edges
Timber structures require careful detailing.
Finished surface and fixing method
Footings/foundations require site specific design based upon geotechnical results
Fasteners are to be true 304 or 316 grade stainless steel. Holes to be pre-drilled
Timber boardwalk to concrete terminations must be designed to prevent trip hazards and excessive gaps opening over time.
