Rye Harbour wins efficiency award

Jackson has won the Environment Agency's Efficiency Award for the work they did on the Rye Harbour Western Training Wall Project, a £9m scheme to re-build the harbour wall in Rye, East Sussex. Delivered 11% under the approved budget, through collaboration and early engagement with the supply chain, the team managed to save over £970k on the project.

The wall plays a vital role, not only in keeping the channel open and thus supporting the multi-million pound economy that relies on Rye Harbour, but also by protecting the adjacent nature reserve which is a SSSI, Special Protection Area and proposed Ramsar site. An inspection of the wall in 2011 revealed it was in a very poor state, so the decision was taken to fast-track the scheme. Due to the urgent nature of the works, the team devised a reduced project programme which involved running the design and construction phases concurrently to save time. Construction of the new 1.5km sheet piled wall began in January 2012, four months after the project's inception, and was completed in December.

Throughout the project the team worked hard to drive down costs, but significant savings were made on two main aspects; the sheet piles, which accounted for almost a third of the entire project cost, and the haul road.

An impressive 4,625 tonnes of sheet piles were required for this project, but by testing the market, the team was able to negotiate a reduction of £100 per tonne with the Environment Agency's sheet pile supplier, which resulted in a saving of £500k. Furthermore, instead of having them shipped to the pile supplier's depot in Shoreham, and then transported to site via road, the team managed to negotiate and get the piles sailed directly to Rye Harbour, where they could be unloaded onto the wharf, thus greatly reducing vehicle movements in Rye, and also reducing CO2.

An extensive temporary access track also had to be constructed over the existing dilapidated access track along the length of the wall to provide a working platform for the construction plant. By negotiating with the materials supplier, the team was able to hire 15,000 tonnes of type 1 fill material to use on the access track, which could be retuned to the supplier at the end of the job, which saved £100k and drastically reduced the amount of waste.

By engaging with the supply chain and working together, the Rye project team achieved significant savings on the project's programme and budget.
