A major residential development on Sydney’s Lower North Shore required ongoing geotechnical engineering support throughout construction to ensure temporary and permanent works were delivered safely and in accordance with design requirements. The project comprised more than 200 apartments across a multi-stage development designed to integrate contemporary residential living with landscaped open space and environmental sustainabilityContinue reading “Multi-storey Residential Development – St Leonards, NSW”

Installing high-voltage cable beneath an operating railway leaves very little room for ground movement. Geotesta was engaged to investigate the ground conditions and assess the potential impacts of a proposed Horizontal Directional Drilling (HDD) crossing beneath a railway corridor in southern Perth area, Western Australia. Our field investigation used Cone Penetration Testing with pore-pressure measurementsContinue reading “HDD Underbore Beneath an Operating Railway Corridor- Perth”

Bunds around crude oil storage play an important part in containing spills, so their condition needs to be well understood. Geotesta was engaged to assess the geotechnical and environmental condition of a crude oil storage bund on Varanus Island. The work began with a desktop review of the bund’s design, construction, inspection, environmental and maintenanceContinue reading “Varanus Island Stage 2, Perth”

Mirvac’s Harbourside is a $2–2.3 billion transformation of the former Harbourside Shopping Centre at Darling Harbour into a mixed-use waterfront precinct, delivering retail, hospitality, premium office space and a 42–48 storey luxury residential tower as part of Darling Harbour’s broader $15 billion renewal. As a Transport for NSW (TfNSW) Technically Assured Organisation (TAO), Geotesta wasContinue reading “Harbourside, Darling Harbour”

As one of Australia’s most significant pieces of new infrastructure, the Western Sydney Airport development required ground investigation at a scale to match, comprehensive coverage across the airport precinct to inform planning, design and construction as the site was built from the ground up. Geotesta’s investigations combined drilling and sampling, geological logging, laboratory testing andContinue reading “Western Sydney Airport, Sydney”

A significant rainfall event across South Gippsland Shire triggered up to nine separate roadside slope failures across Trida and Wild Dog Valley, from instability in cut slopes to embankment failures along partially filled road formations and larger ground movements extending downslope across difficult, complex terrain. Geotesta was engaged to assess the damage and design theContinue reading “South Gippsland Shire Slope Remediation”

Geotesta was engaged by CYP to deliver geotechnical engineering and technical support across key components of the Melbourne Metro Project, one of Victoria’s largest and most complex pieces of transport infrastructure. The scope centred on the Western Work Package, covering the Arden and Parkville station precincts, along with works at Domain Station and the project’sContinue reading “Melbourne Metro”

The West Gate Tunnel is one of Victoria’s largest transport infrastructure undertakings, designed to ease congestion and improve connectivity for Melbourne’s growing western suburbs. Geotesta was engaged to provide geotechnical and geological services across the project’s extensive planning, investigation and construction phases. Field work included drilling and sampling, geological logging, groundwater observations and laboratory testingContinue reading “West Gate Tunnel, Melbourne”

Microsoft engaged Geotesta as its geotechnical partner across a program of hyperscale data centre developments spanning Victoria (MEL04, MEL05 (Yarraville), MEL07 (Tullamarine), MEL11 (Truganina), and the associated MEL11 substation and VDA facilities). The multi-site engagement called for consistent, program-wide geotechnical support from early planning through to construction handover. Site investigations combined boreholes, CPTs, test pits,Continue reading “Microsoft Data Centres, Melbourne”
