1. Summary
The purpose of this report is “Comparison of Rialto and Eureka Towers construction process”. It aims at understanding the differences between the construction process between, not only two buildings, but also between two centuries when one being pri
mitive than the other. Emphasizing on the procurement management techniques for supply chain management with suitable solutions for every problem statement.
Both of the buildings are categorized under high rise buildings. They foster solutions for problems like
Population density
With better medical facilities and medicines, the general mortality rate has been reduced to considerable amount. This causes more population in a specific place thus causing need for shelter. Also, as there is always movement of population from rural areas to city place causes burden for the city.
Land shortfall
There has been land scarcity both nationally and internationally as the population is growing at an alarming pace globally, This shortfall of land has led to increase in their prices thus less affordable.
These problems call for measures to provide shelter to the growing population by the sustainable economical utilization of land.
Historically, high rise buildings have been efficient and aesthetic developments representing symbol of power and power status of any person, place, society or culture.
1. PROJECTS
Here we examine the two iconic towers of Melbourne belonging to the high rise or skyscraper family namely the Eureka and the Rialto towers.
Rialto Tower
It is a skyscraper situated in Melbourne and was the tallest building housing offices i.e was an office building when it opened its doors in 1986. The structure consists of two adjoining towers, with a 43-story wing linked to the 63-story main tower. The salient feature of this building was the observation deck that featured in Melbourne for the first time ever. It was originally built in 1889 by Grollo group.
In 1979 redevelopment proposal was placed before MELBOURNE City Council and construction began in 1982 and was completed 4 years later after a few objections. It was approved as a redevelopment project that used traditional construction processes as not much literature is available for reference about the project.
Eureka Towers
Another skyscraper built by Grocon (Grollo group and partners) which had the honour of being the tallest building of the world when it was opened in 2006 but later succumbed the position to Burj Khalifa. It still holds the record of highest residential building of the world.
As per Designbuild-network site, “The tower is named after the Eureka Stockade rebellion during the 1854 Victoria gold rush (the building crown is gold coloured with a red stripe representing the gold and the bloodshed). The horizontal lines on the building represent the markings on a ruler and the blue façade with white lines is supposed to represent the blue and white flag of the stockade. Also, the markings on a surveyor’s measuring staff are depicted by the white horizontal stripes.”
Various new techniques were employed in the construction of the building. These included foundation, continuous auger piles and high walls.
1. Architectural Features
The height of the Eureka Tower building is 297.3 m or 975 ft with observation deck known as Eureka Skydeck located on the 88th floor. It has 556 apartments serviced by 13 elevators travelling at speed reaching upto 9m/s. The building is relatively slender with a critical structural challenge of resisting the wind loading and control building oscillations in cost effective manner. This is achieved by building water tank on the roof for damping.
In comparison to Eureka tower, the height of Rialto tower is short by 46.3 m so it stands at 251 m but was the first in Melbourne to have skyscraper public observation deck on the 56th floor. It is predominantly an office building with 55 floors on the taller tower and 43 floors on the shorter North tower.

Construction
Due to the proximity to Yarra River, the water table is in close vicinity of the Eureka tower. In fact, it is jut 2m below the tower site as the site area was a reclaimed swampland. This resulted in formation of 2 layers of Basalt above the base layer of Silurian siltstone bedrock necessary for foundation and normally occurred at a depth of 35 m below the surface.
To counteract the menace of swampland resulting in Basalt layer formation, the construction of the building foundation was carried out using special methods involving prepressurised concrete and through employment of slipform method using reinforced concrete. The method involved anchoring, 3 m into the siltstone, 243 continuous augered piles with 750 mm diameter and 28 bored piles of 1500 mm diameter, where conditions dictated.
As for the Rialto tower, there were not enough challenges of this sort as it was a redevelopment process and foundations were already laid. Even, if they were not, the construction technology would not have been at the level, in that era, where these methods would have been thought for....
