9:10 Design And Construction Challenges Associated With The Gateway Bridge Main Span

The main span is built using a cast in-situ balanced cantilever method. When complete, the second Gateway Bridge will join its twin in the top 10 longest of its kind in the world. The second Gateway Bridge includes the addition of a 4.25m wide pedestrian and cycle facility, making it a total 28m wide and requiring a different design and construction method to its existing counterpart. The new bridge also breaks new ground quality-wise, with a requirement set by its owner, Queensland Motorways, to construct with a design life of 300 years. This specification makes it one of, if not the longest design life bridge structures in the world.

9.45 Adapting Lessons From Hurricane Katrina And Using Climate Change Modelling To Design Australia’s Longest Bridge – Houghton Highway

KBR designed the duplicate 2.8 km Houghton Highway Bridge for the Queensland Department of Main Roads. Due to be constructed by 2010, it will be among the first of its kind in the world to incorporate engineering lessons learned from Hurricane Katrina. It has also used modelling to forecast climate change with the result that the bridge deck is four metres higher than the existing one. KBR provided investigation, planning, design and documentation for the project, resulting in a revised bridge location and height that provides for a minimum life of 100 years and minimal damage in the event of a 1-in-2000 year storm.

10:50 Delivering A Complex Bascule Bridge Project By Utilising Innovative Design And Construction Techniques – The Port River Bascule Bridge

The single leaf bascule bridges - one for road traffic and one for rail – are the major elements of Stages 2 and 3 of the PRExy project. The construction of these bridges involved the the development of innovative construction techniques and working over an active waterway.

• Meeting construction and environmental challenges in delivering complex single leaf bascule bridges for road and rail traffic
• Addressing the rail elements with innovative design and fail safe systems
• Ensuring engineering excellence with aesthetics and efficient ongoing management and maintenance of the structures

11:25 Assessing The Deconstruction And Re-Construction Of An Elevated Precast Segmental Viaduct In A City Centre - The New Market Viaduct In Auckland, New Zealand

The focus of the presentation will be in the technical and logistical considerations in developing the solution of replacing this vital piece of infrastructure in this “inner city” environment.

11:45 Achieving Superior Project Delivery Results Through A Collaborative Approach And The Design And Construction Delivery Method –The Sheahan Bridge Duplication, Hume Highway, Gundagai

The $78 million project was a duplication of the original structure over the Murrumbidgee River at Gundagai, immediately upstream of the existing crossing. Funded by the Federal Government and managed by the RTA was officially opened on Monday 25 May 2009.

• Initiating a collaborative approach to develop a high level of constructability into the design process by employing an integrated design team comprising of contractor, client, designer, and temporary works engineers
• Optimising time and cost performance by developing clear KPIS with the client to monitor and measure outcomes
• Working with an internal alliance to produce superior results for the balanced cantilever, increased productivity and reduced costs and time

1:20 Evaluating The Impact Of Early Contractor Involvement In Achieving Excellence In Design & Engineering – The Bakewell Bridge Underpass

The $41 million Underpass, was an extremely complex engineering and construction project, and one of the first to be delivered by the ECI (Early Contractor Involvement) delivery method in Australia. The project won the 2008 Engineers Australia Engineering Excellence Awards, the highest level of achievement in the engineering field.

• Utilising innovative design solutions to optimise structural integrity including soil nail walls, constructing an underpass under five live rail lines and launching the rail bridge into position
• Analysing the role of partnerships in delivering extremely complex engineering projects
• Balancing aesthetic and functional requirements by considering broader urban design and traffic demand

1.55 Assessing Method Related Design Of Bridges

• Evaluating time related constraints in bridge construction to optimise design
• Taking into consideration Space related constraints to design for constructability
• Overcoming time and space related constraints to deliver bridge projects to time, budget and design specifications
• Understanding access related constraints to support design and minimise construction risk

2:15 Assessing The Role Of Detailed Design, Planning & On-Site Integration Of The Construction Engineer In Delivering A Truly Successful Landmark Project - The Phu My Bridge

The $150 million cable-stayed bridge spans the Saigon River and forms part of a new ring road currently being built around the south and east of Ho Chi Minh City. It was completed 4 months ahead of schedule and was opened to traffic at 9.09 am on 9 September 2009.

• Assessing the two phase structure of the project from initial design phase to D&C
• The role of construction methodology and major temporary works design in reducing programme time
• The role of the construction engineer in designing for construction stage loadings and controlling bridge geometry.

3:20 Assessing The Sustainability Of Bridge Assets By Looking At The Role Of Design, Construction And Material Selection

• Evaluating bridge structures and the impact of design in the asset lifecycle
• Constructing for maintenance by understanding environmental impacts and material selection in bridge construction
• Analysing asset management strategies in ensuring the sustainability of bridge structures

3:55 Evaluating Design Mechanisms And Structural Systems When Constructing Duplicate Structures – The Alfords Point Bridge Duplication

The $42 million duplication was constructed on the existing piles and abutments, and provides two lanes for southbound traffic, a breakdown lane/ shoulder and a 3.3m wide shared pedestrian and cyclist path.

• Improving road safety and traffic flow by constructing a duplicate structure that is compatible with the original design
• Utilising existing piles and abutments to optimise design and construction process
• Evaluating maintenance requirements and life-cycle assessment of exiting structures when constructing duplicate structures
