terre rouge - Verdun Link Road
Terre Rouge, Mauritius
A-squared Studio supported the Mauritian Road Authority on this complex highway development. The new highway cuts through topography of high relief and drives through meta-stable residual soils derived from weathered basalt.
Mauritius' equatorial location drives intense tropical weather systems that can pose a major risk to the stability of large cuttings. A-squared carried out slope stability analysis and devised various mitigation measures to ensure the safety of the road-using public on this vital transport link.
London, United Kingdom
A-squared have provided geotechnical analysis and design support for a number of near-shore facilities that will provide handling, laydown and storage area, to enable construction of the Thames Tideway mega-project.
A-squared's involvement includes the detailed analysis and design of twin-sheet pile coffer dams, which incorporate tie-backs, deep fills and significant operational surcharge loading all constructed over soft fluvial clays.

London, United Kingdom
A-squared have provided a number of consultancy services to support the redevelopment of St Giles Square, which has numerous interfaces with critical transport infrastructure, including Tottenham Court Rd Station, Northern Line running tunnels and Crossrail assets.
A-squared carried out complex soil-structure interaction analysis to demonstrate that a unique D-shaped pile the team to install the large diameter piles within 1.1m of the Northern Line tunnel 30 m below ground level (the closest piling operation of its kind to existing tunnels).
GATEWAY UPGRADE NORTH
A-squared were appointed to perform a 3D finite element analysis to assess the impact of the operation of a large piling rig on the integrity of existing controlled-modulus-columns, supporting a highway embankment constructed over soft soils.
Navitus Bay Offshore Windfarm
nr Isle of Wight, UK
A-squared Studio provided high quality ground investigation interpretation followed by a turbine foundation design optimisation exercise for the large scale offshore wind farm. The geotechnical design accounted for cyclic loading and geotechnical fatigue within complex ground conditions.
The collaboration between A-squared and Geo2 BV ensured the delivery of a broad optioneering exercise to aid the feasibility assessment of the project.
A-squared Studio developed the Copenhagen Citiringen Metro tender design for selected metro tunnels and station boxes.
A series of ground movement analyses were undertaken in order to present a building damage assessment of buildings located within the ground movement corridor/zone of influence associated with the construction of the metro tunnel and station boxes. In excess of four thousand buildings were included in the assessment.
