3.11.3.1 General Requirements
a) Finishes will be non-combustible, easily cleaned, durable and be replaceable with the
minimum of disruption to station operations. Finishes, which minimise the impact of
graffiti and are resistant to graffiti solvents are to be considered.
b) Life Cycle
The general design service life should be 100 years with various parts of the station
having the following design life periods:
Drainage elements that are not accessible 100 years
Drainage elements that are accessible for refurbishment 20 years
Sign faces 20 years
Support structures 50 years
Other station furniture 40 years
Lighting 20 years
General structures 100 years
Architectural linings 40 years
Retaining walls 100 years
Mechanical and electrical equipment 40 years
Fire protection equipment 50 years
Floor finishes 40 years
c) Corrosion, Air Pressure and Vibration
Selected materials will be reviewed for corrosion resistance including stray electric
currents and also the effects of air pressure and vibration due to train movements on
materials, fixings and support systems.
d) Moisture Penetration
All finishes will be protected against the effects of moisture penetration from any ground
water, especially in an underground station. In an underground station lining shall be
designed on the basis of a groundwater seepage rate limited to a maximum of 0.75l/s per
10,000m² of excavated surface area.
e) Floor Finishes
Floor finishes in public areas where water or wash down water is present will have a nonslip textured finish compliant with AS 4586, AS 1428.1 and 2, HB 197.
f) Integral Colours
Wherever possible finishes will have integral colour through the thickness of the material.
g) Thickness of material finishes for floors
Floor finish materials will be of sufficient mass and thickness to resist any possible train
generated vibrations and materials capable of providing large slabs will be used.
Floor finish materials will not be discoloured by materials and chemicals used to clean
adjacent wall surfaces.
h) Stairs
Careful consideration will be given to the selection of materials for nosings and stair
treads, compliance with AS1428.2 should be sought so as to ensure colour contrast and
slip prevention. i) Walls and columns
For walls and columns consideration will be given to the selection of finishes up to
2600mm above floor level within public reach. Materials will be resistant to vandalism
and wear.
j) Maintenance and Access
• All materials and surfaces are to be high quality, cost effective over the life of the
station and easily cleaned and managed.
• The following requirements concerning maintenance and maintenance access are
outlined below.
• Standardisation – Standard building and equipment elements will be used for ease
of local procurement and to minimise the inventory of replacement items to be held
in stock.
• Brake Dust – Materials and finishes will be selected to minimise the need for special
cleaning equipment and shall take into account the implications of train brake dust.
Surfaces are to be cleaned without the need for special cleaning equipment or
track possession and in the case of platforms, without traction power outage.
• General Access – All authorised areas of a RailCorp Station shall be covered by a
master keyed system
• Ladders and catwalks – Elevated areas of stations including roofs, ceilings and
soffits will be readily accessible by either moveable ladders, staging or by fixed
installations comprising ladders and as required.
• Access above stairs, escalators and light wells – Access will be provided to lights
and other fixtures in the situations described above.
• Access via the permanent way* – Normal station maintenance, including access for
maintenance equipment, will generally not be conducted from the permanent way.
• Access to all voids and ventilation shafts – Suitable, safe inspection or physical
access will be provided to all voids and shafts. All voids shall be ventilated to the
relevant BCA standard.
• Platform Pits – Access to platform pits will be away from the platform edge where
possible and avoid key circulation routes.
• Storage Areas – will be provided at the particular station for all required specific
access and maintenance equipment
