flood mitigation project

EDMONTON, Alberta & NEW YORK & SYDNEY, NSW–(BUSINESS WIRE)–TSX, NYSE:STN

Stantec, a global engineering, consulting and construction firm, along
with joint venture partner GHD has been awarded a $14.5 million design
services contract by WaterNSW for the Warragamba Dam Raise west of
Sydney in New South Wales, Australia.

The Warragamba Dam Raising Concept Design will look to increase the
height of the existing dam, allowing it to be used for flood mitigation
purposes that will benefit the downstream community. Since 1960, twenty
moderate to major significant floods have impacted the Hawkesbury-Nepean
Valley.

“We are proud to work with WaterNSW on this exciting project and have
assembled a technical team who bring experience from dam raise projects
completed around the world,” said Ashok Sukumaran, Stantec’s General
Manager for Water in Australia. “This mix of local and international
expertise will deliver a complex design that meets safety standards and
optimizes the dam configuration for the purposes of flood mitigation.”

The services provided by the partnership of Stantec and GHD will include
developing a cost-effective and safe design for raising Warragamba Dam,
while addressing and mitigating any project impacts. The Stantec and GHD
team combines relevant water infrastructure and engineering experience
to create innovative designs with proven technologies. Design services
for the Warragamba Dam Raising Concept are expected to be completed by
early 2019.

“Delivery for complex dams and hydropower projects is one of Stantec’s
core strengths and we are proud to be able to bring the best of
Stantec’s global expertise in dam raise design to a major client in
Australia,” said Mario Finis, global leader of WaterPower & Dams for
Stantec.

feasibility studies, detailed design and construction management from
