Hochtief subsidiary Flatiron has won two climate adaptation and resilience projects worth $327m in Texas and Virginia.

The City of Virginia Beach selected the company alongside Dutch consulting engineer Arcadis to carry out the first phase of a project to improve stormwater management and protect the fresh water supplies.

The contract, which is worth up to $275m, will include the use of pump stations, tide gates, flood barriers and drainage channel upgrades to better manage water storage and drainage.

In Texas, Flatiron has signed a $102m contract with the Army Corps of Engineers to provide surge protection upgrades to three pump stations in Port Arthur.

Flatiron will undertake concrete flood wall replacement, levee armouring, and replace earthen levees. Preliminary work is to begin this month.

The projects in Texas and Virginia join other resiliency jobs already under way. For example, Flatiron is implementing a stormwater management strategy in New Jersey worth $251m, and is working on mitigate rising sea levels at Battery Park City, Manhattan, as part of a team that also includes Bjark Ingels Group, Turner Construction and WSP.
