Page 1 of 12 Consultancy Services Brief Alderley Avenue Bridge Replacement

1. INTRODUCTION 1.1. Background

Alderley Avenue Overbridge is located at the 5.130km on the Ferny Grove Line, servicing local vehicular and pedestrian traffic in Alderley, QLD. It is currently a three span timber bridge which requires major maintenance. As part of TSC funding, approvals have been given for the detailed design of a single span concrete replacement bridge to be completed.

There is also a proposal to close the nearby Frederick St (4.79km on the Ferny Grove Line) overbridge to vehicular traffic, and for replacing it with a single span bicycle/pedestrian only bridge. The existing bridge is also a three span timber bridge in a similar condition to the Alderley Avenue Bridge. The design of this bridge is to be included in this package as a provisional item only, and will proceed if sufficient funding is available.

Queensland Rail requires the completion of concept designs; detailed design and documentation for the replacement bridges.

Adjacent to the Alderley Avenue bridge site is a steel truss pedestrian footbridge which is owned by the Brisbane City Council (BCC) and must remain in place.

1.2. Stakeholders Objectives Queensland Rail and BCC’s broad objectives for a replacement overbridge for Alderley Avenue are:

• Replace the timber bridge with a single span concrete bridge with extended maintenance free life;

• Provide an overbridge for two way traffic and pedestrian access on both sides of the bridge;

• Speed of construction to minimise road closure time;

• Adjacent existing truss footbridge to remain in place;

• Railway to remain operational during construction;

• Improved vertical clearance over the railway.


Document title

Queensland Rail and BCC’s broad objectives for a replacement overbridge for Frederick St are:

• Replace the timber bridge with a single span bicycle/pedestrian bridge with extended maintenance free life;

• Railway to remain operational during construction;

• Improved vertical clearance over the railway.

1.3. Communications Protocol The Queensland Rail liaison person for the purpose of this project is the appointed Project Coordinator (Brendon Gill – Ph (07) 3046 7724). All formal communications and directives must be channelled / authorised by the Project Coordinator.

Queensland Rail has also appointed a Project Manager (Tim Woltmann – Ph (07) 3046 7420) to deal with the broader issues of the project.

BCC contacts include Principal Engineer Central, Douglas Lee (Ph (07) 3403 4830) and City Assets Engineer, Jayasiri Gunaratne (Ph (07) 3178 3617).

2. The PROJECT 2.1. Scope

This project involves the detailed design and documentation for a replacement over bridge at Alderley Avenue and Cycle/Pedestrian bridge replacement at Frederick St. Both structures will span over the rail corridor which includes two tracks and all associated services and structures. Alderley Avenue is to be a single span concrete bridge with two traffic lanes and pedestrian access on both sides of the bridge. Frederick St Bridge is also to be a single span bridge allowing only cycle and pedestrian access across the rail corridor. Both bridges must meet all Queensland Rail rail corridor clearance and BCC road and footpath width requirements. Bridge approaches; adjacent road intersections; residential dwellings; services and all related civil works must also be considered and addressed in the design and documentation.
