Scope
Description
Havant Borough Council (the council) has undertaken market engagement for the construction delivery of a Flood and Coastal Erosion Risk Management (FCERM) Scheme at Langstone, Havant, Hampshire, UK (Langstone Coastal Scheme).
Works are required to deliver the Scheme that covers approximately 1km of tidal coastline in Havant, providing increased flood and erosion risk protection to 53 residential and 4 business properties, critical infrastructure including the A3023 (the only highway access to Hayling Island) and a number of heritage assets.
The flood defences have been designed with a 50-year design life and to provide a present day, 1:200 year (o.5% Annual Exceedance Probability (AEP)) standard of protection against tidal still water level.
The frontage is popular with locals and visitors due to its unique setting between two harbours and is an important area for cultural heritage, with six listed buildings and two Conservation Areas. There is a network of footpaths which also features the historic Wadeway, Solent Way and Hayling Billy Line (which also doubles as a cycle route). There are also two pubs in Langstone (the Royal Oak and the Ship Inn) and the harbours are popular for watersports.
The council is proposing an initial contract period for delivery for the works of 2 years and 7 months, A longer term or additional extension periods may be required, subject to future plans for the works.
The total estimated value of the Scheme is between £12million and £14million.

Engagement process description
In 2024, the council undertook Market Engagement to gather feedback on the Scheme ahead of a procurement process, to take place under the Public Contract Regulations, 2015. The aim of the engagement was to gauge supplier interest in the Scheme, and to understand market preferences on the structure of a procurement process to ensure maximum supplier engagement when the procurement process went live.
Market Engagement took the form of meetings with four suppliers identified from either their known experience in constructing coastal flood protection schemes of similar scale and complexity, and through suitable frameworks. In addition, ECI was conducted with a commissioned supplier to provide feedback on the buildability of the scheme during the design phase.
The conclusions of the market engagement were:
- There was sufficient interest in the scheme to undertake a procurement process.
- A Restricted Procedure, rather than an Open Procedure or call-off from a suitable construction framework would achieve the most advantageous results for the council in terms of programme, quality and cost.
- The project would benefit from an Early Contractor Involvement (ECI) stage with the selected works supplier to assist in identifying improvements in phasing and any works that can be undertaken earlier to assist in scheme delivery and cost reduction.
- An ECI stage could be effectively governed by including X22 in the NEC4 ECC contract terms.
A Restricted Procedure was started under the Public Contract Regulations, 2015. However, due to an administrative error, this procurement process could not be completed and is due to re-commence under the Procurement Act, 2023, as a Competitive Flexible Procedure (CFP).
The proposed CFP will be based on the preferred Restricted Process identified during the previously undertaken market engagement, with no further market engagement activities planned in preparation for this new process.
Participation in completed market engagement activities is not a prerequisite for participating in any future procurement process. Suppliers that did engage with the council will not receive any preferential treatment in any future procurement process and prior participation is not an indication of selection, or a guarantee of future work.
