Ulverston FAS

Project: Ulverston Flood Alleviation Scheme (FAS)

Location: Ulverston, Cumbria

Value band: £5m-10m

Client: Environment Agency

More: WaterProjectsOnline

With a history of flooding, the Cumbrian town of Ulverston required major flood defence improvements to provide 1-in-100 year protection to over 500 properties.

We raised existing defences and refurbished long culverts. Our solution achieved a cost saving of 17% and throughout utilised construction techniques that minimised disruption to the busy market town.

Clementhorpe FAS

Project: Clementhorpe Flood Alleviation Scheme (FAS)

Location: City of York

Value band: £5m-10m

Client: Environment Agency

Our flood defence work at Clementhorpe is the latest in a line of JBA Bentley projects within the York Flood Alleviation Scheme, which is lowering flood risk in central York, a city historically prone to flooding. 

Clementhorpe is one of 18 flood ‘cells’ identified as vulnerable, with 135 homes at risk. Our solution includes a large bi-fold flood gate, smaller flip-up gate, seven flood walls, road raising, and an underground seepage mitigation barrier constructed using ‘deep soil mixing’, designed to make the ground semi-impermeable. By using deep soil mixing, our solution is both sustainable and cost-efficient. 

Sheaf Screen

Project: Sheaf Screen

Location: Sheffield, South Yorkshire

Value: £1m-5m

Client: Environment Agency

Awards: International Green Apple - Environmental Best Practice

With the screen and associated infrastructure at Sheaf in poor condition, with some elements operating beyond the end of their service life, the asset required modernisation.

Carbon savings in excess of 700T were made as we designed and constructed a new screen and innovative solution for debris clearance, utilising an automatic grab that significantly reduces the number of site visits required by our client's staff.

Great Yarmouth

Project: Great Yarmouth Tidal Defence Project

Location: Great Yarmouth, Norfolk

Value band: £30m+

Client: Environment Agency

Awards: British Construction Industry Awards - Environment and Sustainability Initiative of the Year

NEC Martin Barnes Awards - Runner-Up - Contractor of the Year

Great Yarmouth has a history of flooding; in 2013, 9,000 people were urged to evacuate when the highest ever tide was recorded on the town’s river.

We have refurbished 4km of existing flood defence walls, raising defences and installing cathodic protection. Instead of just replacing quay piling as originally proposed, we refurbished existing defences, reducing costs on this element
of works by 47% and carbon by 60%.
