The council, in collaboration with the Eastern Solent Coastal Partnership (ESCP), has published a contract notice for a coastal defence contractor to deliver new improved flood defences along 4.5km of seafront, from Old Portsmouth to Eastney.

However, Balfour Beatty is already on board – it was awarded a £1m pre-construction services contract in June 2017 and heads the integrated design team that brought the scheme through the planning application stage– so it seems well placed to win the main works contract. Design consultants are Arup and Ramboll, while Faithful & Gould is cost consultant.

The current sea defences at Southsea are reaching the end of their lifespan and need renewing. Portsmouth City Council’s plans aim to improve the seafront and stimulate regeneration as well as protect the community and its heritage.

Contract value is estimated as being between £95m and £110m.

The scheme divides Southsea frontage into six sections that will be built in phases. The aspiration is to start on site in March 2020 and complete the sixth and final phase in 2028.

Portsmouth City Council is now tendering for two commissions: a design supplier and a construction contractor. The construction contractor will be selected by a  two stage tender. The first stage is the supplier status questionnaire which is available at and open to all. The deadline is 24th May 2019. The council is targeting to have secured a contractor by 6th September 2019.

The tender for design consultant (detailed designers) is looking for a supplier to bring the plans through to construction level. This design tender was offered to contractors who sit on the flood and coastal erosion risk management consultancy services framework that was set up in 2016 to ensure greater consistency from a list of multi-disciplined consultancies that have both the expertise and resources to undertake a project of this scale.
