GENERAL
This Part specifies the requirements for the construction of tram platforms, including secondary paving, furniture,
fixtures and fittings, and electrical requirements.
Reference shall be made to the following documents:
AS 1657
Fixed Platforms, Walkways, Stairs and Ladders
The type, configuration and extent of tram platform infrastructure shall be in accordance with the Contract Specific
Requirements or the Drawings. If there are no applicable requirements, the requirements specified in this Part shall
apply.
All tram platform features shall be free of irregularities that could present hazards to users and shall smoothly abut
any existing and new surface.
2.
PLATFORM CLEARANCES
The clearance envelopes to the tram platform shall be in accordance with Standard Drawings 200-A2-2003-104
“Tram System Maximum Stock Outline” and 301-A2-2003-102 “Tram System Minimum Structure Outline”.
The Contractor shall ensure that the top of the tram platform at its edge is 235mm above the top of the rail, with the
following tolerances applicable:
+0 / -10 mm vertical – distance measured from top of rail to top of platform edge; and
-0 / +10 mm horizontal – distance measured from vertical face of platform to gauge face of near side rail,
where a negative value means a reduction in the clearance dimension.
3.
SITE PREPARATION AND EARTHWORKS
3.1
General
Site preparation and earthworks construction associated with the platforms shall be constructed in accordance with
Part 210 "Earthworks".
3.2
Base
The base layer beneath the platforms (and adjacent track structure) shall be constructed in accordance with Part 215
"Supply of Pavement Materials" and Part 220 "Pavement – General".
3.3

of Structural Steel".
5.
CONCRETE
5.1
General
The design, supply and placement of structural concrete shall be in accordance with Division 3 "Concrete".
5.2

PAVING
6.1
General
The platforms shall be paved in accordance with this Specification and to the extent and types indicated in the
Contract Specific Requirements or on the Drawings.
6.2
Laying Paving Units
6.2.1
Placing Paving
Paving units shall be placed on the uncompacted screeded sand bed to the laying pattern shown on the Drawings.
Paving units shall be placed to achieve gaps nominally 2 mm to 4 mm wide between adjacent units such that all
joints are correctly aligned. Except where it is necessary to correct any minor variations occurring in the laying bond,
the paving units shall not be hammered into position. Where adjustment of position is necessary care shall be taken
to avoid premature compaction of the sand bedding.
The Contractor shall be responsible for setting out control lines to ensure the paving is not out of square before
laying. Where paving patterns appear ambiguous or the pattern does not fit in practice as shown on the Drawings,
the Contractor shall clarify the final layout with the Superintendent.
The pavers shall be specifically for the purpose of pedestrian paving, having all relevant attributes, e.g. slip
resistance, etc. The pavers shall be laid in non-vehicular trafficable areas on a sand bed, over a concrete base as
specified below
Paver Type and Minimum Thickness:
Bedding Material and Minimum Thickness:
Base Material and Minimum Thickness:
300 x 300 x 30 mm Concrete
15mm (max) Sa-C Type C Sand
In accordance with the Drawings or Contract Specific
Requirements
The joints between pavers shall be filled with a pre-mixed grout no less than 48 hours after paving. Pedestrian traffic
(including contractors) shall be prevented from accessing paved areas within the first 24 hours of grout curing. No
vehicular traffic shall be allowed on the finished pavement.
Paving shall be sealed with an appropriate sealer, to enable graffiti removal.
No paving may commence until the concrete platform base has cured for a minimum of 7 days.
Diagonal cuts in paving shall not be permitted unless approved.
Paving shall not be laid when the ambient temperature is less than +5˚C or higher than +30˚C.

6.2.2
Specification: Part 940 Tram Platforms
Header Course
Platforms shall have one row of header bricks securely fixed along each edge and where shown on the Drawings.
6.2.3
Paving Finish and Around Service Inspection Pits, and Platform Fixtures, etc.
All surfaces shall be finished in conformity with the lines, grades and cross sections shown on the Drawings or
specified within the following limits:
Surface Finish
Paving shall be shaped to match the level of existing fixtures, (e.g. pit covers, kerb, edging, etc) to within 2 mm
tolerance. Elsewhere the deviation of the finished work from line or level shall not exceed 3 mm at any point, and
the rate of change of deviation from line or level shall not exceed 5 mm in 10 m or 0 mm between adjacent pavers.
Except on curves or in shaped areas, the deviation of the finished work from a 3 m straightedge shall not exceed
3 mm at any point.
Unless otherwise specified, all paving shall be shaped to shed surface water from the entire paved area in the
direction of natural slope or towards constructed surface drains. The slope at any point on the paving except on a
ridge shall be not less than 1.5%.
Adjustment of Existing Service Inspection Pits
Where an existing service inspection pit is above or below the proposed platform level, the Contractor shall make the
necessary arrangements to adjust the service inspection pit to the new platform levels. Refer Clause 110.9 "Utility
Services.
Steel Service Inspection Pits and Stormwater Channel
Block paving shall be placed around small square steel service inspection pits and stormwater channel such that
paving units match the pits or channel. The edge of the paving shall not be greater than 4 mm from the pit or
channel, either vertically or horizontally. The Contractor shall make allowance to cut, if necessary, the paving units
around these pits or channels.
Other Service Inspection Pits and Platform Fixtures, etc.
Unless otherwise shown on the Drawings, concrete infill shall be placed around service inspection pits (other than
those referred to above), survey marks, poles and furniture within the paved.
Concrete shall be Grade 25 (or a 1:2:3 mix of cement, sand and 10 mm aggregate) and shall be placed to a minimum
depth of 75 mm. The concrete shall be coloured to match the surrounding block paving. Prior to placing the
concrete infill, a sample of the colour shall be submitted for approval.
6.2.4
Tactile Ground Surface Indicators
Tactile Ground Surface Indicators (TGSI’s) shall be placed to the extent and types indicated in the Contract Specific
Requirements or on the Drawings, and match the paving grid and provide at least a 30% contrast both in terms of
colour and texture.
TGSI's shall be laid in accordance with the manufacturers instructions and conform to a minimum level "V" slip
resistance rating in accordance with AS 4586.
Any stains resulting from grouts and adhesives on the TGI’s shall be removed as soon as practicable after it occurs.
