Yarra One Project 3
1. Introduction
This report presents analysis of the structure and construction process/planning of Yarra One.
Yarra One is a27-storey residential apartment tower located at 16-22 Claremont Street in South
Yarra, Melbourne, Australia. The building comprises of 256 dwellings that will be built over a
total area of 37, 500 square meters (four penthouse apartments, 42 3-bedroom apartments, 158 2-
bedroom apartments and 52 1-bedroom apartments). The developer of the project is EcoWorld
International and it was designed by Fender Katsalidis Architect, an internationally-distinguished
and award-winning Australian architecture company. Construction of the project started on July
6, 2018 and is scheduled to be completed in July 2020 (construction duration of 25 months). The
project is estimated to cost A$243 million (Khoo, 2018).
2. Structure
2.1. Basement
The basement of the building is built from a typical retention system that comprises of
engineered pile footings. Pile footing is a type of deep foundation that is driven into the ground
to create a steady support for the superstructure that is built on it. Pile footings have the capacity
to take higher loads and therefore are suitable for buildings with very heavy concentrated loads
like a water tank, bridge or high rise building (Letsois, et al., 2014); (Understand Building
Construction, (n.d.)). The engineered piles used in this project are made of precast concrete.
Since the building is in an urban area and close to other structures, it is necessary to minimize
vibrations when installing piles. For this reason, micropiles are the best for this project. A
micropile is constructed by digging a hole of a bigger diameter than that of the pile and depth
equal to the length of the pile, pushing or lowering a precast concrete pile into the hole, and then
pouring a concrete grout into the gap between the earth and the pile. The substructure is

completed by constructing a large concrete slab on top of the concrete piles. Other renowned
buildings with this type of basement structure include Shard in London and Burj Khalifa in
Dubai (BBC, (n.d.)).
The typical retention structure of the building’s basement was selected by considering several
factors such as the location of the building, the type and quantity of loads of the superstructure,
the intended function of the building.
2.2. Atrium
The main structure of the atrium comprises of timber frames, natural stone and luxurious
greenery. These have been selected to create a warm atmosphere for the atrium where the public
and residents can enjoy. The atrium is multipurpose and it features retail spaces, restaurants and
cafes where people can meet to shop, dine and relax. The structure of the atrium serves its
intended purpose of serving as a pronounced entrance to the tower for residents and also a public
space where visitors can sit and enjoy (Hickory Building Innovation, 2018). The atrium exterior
of the building is as shown in Figure 1 below.
