SMEC to Deliver Free-Flow Motorway in Adelaide, Australia

23 February 2016

The Gateway South Consortium, comprised of the Design Joint Venture (SMEC, Jacobs and KBR)
and Construction Joint Venture (Fulton Hogan and Laing OíRourke), has been engaged by the
Department of Planning, Transport and Infrastructure to design and construct the A$620 million
Darlington Upgrade Project in Adelaide, Australia.

This project forms part of the Adelaide North-South Corridor Upgrade, a key component in South
ongoing transport infrastructure strategy. This 78 km north-south freight route will be
upgraded to eliminate bottlenecks and provide non-stop road links to connect rapidly expanding
industrial and residential growth areas throughout Adelaide.

The Darlington Upgrade Project will comprise the upgrade of 3.3 km of Main South Road, including
a non-stop motorway between the Southern Expressway and Tonsley Boulevard requiring grade
separations at five intersections. SMEC (in association with its Joint Venture partners) will be
responsible for design coordination, traffic modelling, traffic engineering, bridge and road design,
drainage, and Intelligent Transportation System (ITS) design.

A key challenge of the project is overcoming the complexity of a diverse mix of traffic users and
high traffic volumes, combined with mixed residential, industrial, institutional and commercial land
use along the corridor. Clever and innovative engineering is required to overcome these constraints
in such a heavily developed brownfield environment.

SMEC has enjoyed much success along the Adelaide North-South Corridor, having delivered: the
A$564 million Northern Expressway (NEXY); A$842 million South Road Superway; and a major
planning study in 2014 for the Darlington Upgrade Project, which ultimately enabled the State and
Federal funding to make the current Darlington Upgrade Project possible. SMEC has also prepared
tender designs for the $407 million Southern Expressway Duplication and the A$896 million
Torrens Road to River Torrens Project (in an alliance arrangement).

The key to SMECís continued success on the project is the ability to maintain core relationships and
to align the Company with winning contractors and consortia. Successful delivery is the combined
result of SMECís high-calibre specialist design personnel, attention to design quality and timeliness,
and the efficiencies that result from a flat management structure with Australian ownership.
SMECís success in securing the Darlington Upgrade Project, and the Companyís prominent role in
bringing the multibillion dollar Adelaide North-South Corridor to life, will further enhance SMECís
reputation as one of the leading infrastructure consultancies in Adelaide.
