INTRODUCTION
Sydney Bridge among the few bridges that make the city to be known around the world. It is
made of steel, situated in Sydney and crosses port of Jackson. British firm Dorman Long won
the tender of designing an arch bridge which was completed and opened 10 years later. The
bridge was created to hold 6 traffic lanes: 2 lanes for the trains, 2 footpaths and two lanes for
trams. There was the idea of building the Sydney Bridge as cantilever bridge which was
approved by the NSW Legislative Assembly but the council of legislation disagreed since it was
the realized that funds should be channeled into war effort. After World war one, Bradfield
returned from looking the tenders abroad with the idea of arch bridge design.
The arch bridge design was approved since it was cost-effective and stronger compared to other
proposed solutions. The building of the bridge occurred at the same period of construction of the
underground railway system in Sydney hence the Bridge was conceived to accommodate the
railway traffic also. This report illustrates the conceptual design, stakeholders need, and system
requirement of the Sydney Harbor Bridge. The Hong Kong Bridge consists of 3 artificial inlets,
one submarine tunnel and continued 3 cabled bridges.
STAKEHOLDERS’ NEEDS
This entails the expectations of the major shareholders and investors involved in the construction
and the bridge design. It represents the views of business users, acquirers and other stakeholders
as they relate to opportunity. The building of the bridge was opinionated by the bridge of Hell
Gate in the New York and become the tallest structure worldwide and sixth longest in terms of
spanning. The main stakeholder was British Firm, Midddlesbrough. The original contractor of
the bridge was John Bradfield but Sir Ralph Freeman was the one who was selected by the
company to build the bridge. The project engineer was Gilbert Roberts and Georges Camille was

the consulting engineer. The decision to construct the Sydney Bridge was to join the south and
north shore of Sydney harbour. Ferry organizations were not keen on harbour crossing and had a
monopoly of getting people and goods across the harbour. There was more traffic of ferry in the
harbour and royal commission determined that the bridge should be constructed between the two
banks (Avşar, 2011).
The Hong Kong Bridge was built to improve flow of goods, labour and market worldwide. The
bridge was also to minimize traffics and congestions, improve tourisms, reduce carbon
emissions, to improve networks of transport and create employment opportunities. The aim of
building Story Bridge was to reduce traffic congestion at the bridge if Victoria and also to create
job opportunities.

Business needs and requirement
Business needs are the gaps between the goals of the business and the current states. needs are
the key drivers of change in the business identified as the requirements and they are implemented
by hiring individuals, buying goods, operation transformation and implementing projects. As the
