Considerately shoring up Blackpool and Fleetwood’s coastal flood defences – Balfour Beatty
Balfour Beatty’s Rossall Coastal Defence Scheme project along the Lancashire coastline has received exceptional scores in all areas of the Scheme’s Code of Considerate Practice.
The Rossall Coastal Protection Scheme is part of a programme of planned coastal civil engineering works on the Fylde Coast, governed by the North West and North Wales Shoreline Management Plan.
The project is to renew 1.8km of existing sea defences at Rossall, located between Fleetwood and Blackpool. The fortifications will protect 7500 homes and infrastructure, in line with a flood return period (frequency of severe flooding) being greater than 0.5% (1:200 years). The defences have a 100-year design life, taking into account sea level rise.
The Rossall scheme was awarded to Balfour Beatty in October 2013 as a design and build scheme, with the main construction commencing in 2014. The coastal defences were opened to the public this year and there are some additional landscaping works due for completion in spring 2018.
The scheme was developed by the Fylde Peninsular Coastal Programme with the promoters Wyre Council, in conjunction with Blackpool Borough Council, Fylde Council and the Environment Agency. It is one of three schemes in the area. The landscape strategy is to provide a network of pathways that traverse the landform enabling access between Fairway and the promenade.
Outlining the work, Balfour Beatty Project Manager, Phil Dilworth said:
“The construction of the defences consists of 18 rock armour groynes and rock revetment (each rock weighing 2.5-10.5 tonnes each) leading to a sheet pile wall.
“There is then a sequence of pre-cast revetments leading to a curved wave wall. Behind the wave wall is the lower and upper promenade consisting of a high quality exposed quartz aggregate finish with an intermediate block providing the change in level. There is then a rear wall with the landscaping works at the rear.”
One of the main challenges the team faced on this project was ensuring the safe and efficient delivery of the vast quantity of materials which included:
- 243,000 tonnes of rock armour (2.5-10.5 tonnes each rock)
- 95.000 tonnes of under layer Rock (0.3 to 1 tonne each)
- 9,700 pre-cast concrete units ( 1 tonne to 14 tonnes each)
- 230,000 tonnes of 6N/Type 1 Fill
- 45,000m3 of Insitu Concrete
Explaining how the team tackled this challenge, Phil explained:
“An approved route was developed with Lancashire County Council, details of which were included on all orders. Monitoring of the route was a constant exercise and we purchased a SID (Speed Indication Display) camera – the smiley face one that displays your speed if you’re good. We set this up in different locations and the speed camera and vibration monitor were all in daily use.
“Complaints are dealt with quickly with a personal response. The key thing we have done as a team is to hold open mornings – these are a general invitation for the public. If we do have complaints, the individual is personally invited so they can meet us, ask direct questions and get specific answers; this approach changed some of the early complainants to become advocates of the project.
“The key success has been the teamwork approach by Balfour Beatty and Wyre Council to both manage the contract, while effectively dealing with the public. By all of us adopting a proactive and positive approach the requirements of the Scheme have become a natural element of our activities.”
You can read about just a few of the Balfour Beatty project team’s many examples of best practice to comply with the Considerate Constructors Scheme, by clicking on the sliders below:
- External areas of the site were kept clean and tidy, with a bin provided for the public and hoarding kept clean and presentable.
- Litter picks were regularly carried out and there were daily inspections by staff.
- All facilities, vehicles, plant and stored materials were screened and motion-activated lighting pointed away from residents to reduce impact. The same approach was taken with regards to satellite welfare facilities.
- The perimeter and surrounding areas were kept clean and tidy with a road sweeper, tractor and bowser used to dampen down roads.
- Members of the public and visitors could attend open mornings on site and there were regular updates posted in visitors’ cabins, on noticeboards and web pages. Open fencing was also used at access points to provide a viewing area and Heras fencing surrounded the main landscaping works.
- Daily visual checks of the compounds and waste and storage areas were carried out and recorded weekly, with storage at the main compound under the control of a store man.
- Positive press about the project was achieved in local, national, radio and television interviews.
- Letter drops were carried out detailing various events and news such as Christmas updates, Chatsworth Piling and the Larkholme Grasslands Consultations.

- A traffic management plan was implemented and each access had a dedicated vehicle marshal.
- An agreed delivery route was in place, delivery routes were included on all orders and there were set delivery times.
- In terms of local employment, 85 members of the workforce were employed from Blackpool, Fleetwood and the St Anne’s area; a further 197 were employed from within a 50-mile radius.
