The procurement stage has progressed from planning to the award phase as of 1st May 2026, with a contract period projected to start on 1st June 2026 and conclude by December 2029. The buyer, Havant Borough Council, based in the UK, seeks to engage a qualified contractor through this selective procurement process.

Ideal candidates would be companies capable of delivering large-scale infrastructure projects within environmentally sensitive areas, such as Jackson Civil Engineering Ltd, which has been awarded the contract. The scheme's complexity, particularly due to its tidal and linear site constraints, necessitates contractors with robust project management capabilities and innovative approaches to achieve cost savings and enhance buildability. This contract offers potential for lasting business growth through subsequent projects and emergency works, showcasing a commitment to environmental sustainability and community engagement around coastal defence initiatives.

Notice Information

Notice Title

Langstone Coastal Defence Scheme

Notice Description

Havant Borough Council (the council) was seeking a suitably qualified and experienced construction contractor for the construction delivery or a flood and coastal erosion risk management (FCERM) scheme at Langstone, Havant, UK (the scheme). The scheme covers approximately 1km of coastline in Havant, extending from SU 71655 04962 in the west to SE 7191 0501 in the east. The alignment protects the largest number of properties and critical infrastructure including the A3023 (the only highway access to Hayling Island) and a number of heritage assets. This includes 53 residential and 4 business properties which will be better protected through implementation of this scheme. A further 6 residential properties not currently at risk, but which will become at risk by 2040 due to climate change will also be better protected within the 50-year lifetime of this scheme. The frontage is 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 scheme involves the construction of 1km of new, continuous defences which consist of earth raising, flood embankments, reinforced concrete flood walls, sheet-piled walls, flood glass, flood gates and demountable defences. The history and development of the scheme can be found at: https://coastalpartners.org.uk/project/langstone-coastal-defence-scheme/. Delivery of the works will be managed using an NEC4 Engineering and Construction Contract (ECC), utilising Option C - activity schedule with target cost. The contract will be managed by an accredited NEC4 Project Manager and administered using CEMAR software, hosted by the council. The contract is due to commence on 1st May 2026 and will run for a period of 2.5 years, with completion no later than 1st December 2030. Following contract commencement, the council will engage the contractor to work collaboratively with the aim of reducing the costs, increasing buildability, mitigating risks, and making the programme more resilient where possible. This stage of Early Contractor Involvement (ECI) is incentivised in clause X22 of the Contract Data. The NEC4 ECC option C is a target cost contract with a pain/gain share mechanism, whereby any savings (gain) or additional costs (pain) are shared between the council and the contractor. The pain/gain share mechanism is set out in the contract data and is summarised below: Where the final cost is: - Less than 80% of the target cost, the Contractor's share is 20% - Between 80% and 120% of the target cost, the Contractor's share is 50% - More than 120% of the target cost, the Contractor's share is 100% The value of the contract is estimated to be in the region of PS12million to PS14million excluding VAT.

Lot Information

Lot 1

Options: The council reserves the right (but is not obligated) to award a contract(s) for additional works that may arise within the Coastal Partners area during the contract period, to the winning supplier from this procurement. The council envisages that such an award may be necessary in the event of emergency repair or replacement works that: - arise as a result of the scheme itself, for example, the materialisation of a currently unknown risk - become necessary in the event of emergency repair or replacement works of coastal assess within the Coastal Partners frontage not associated with the scheme, where an immediate response is considered necessary for protecting life and property. Any contract for additional works will be awarded in accordance with Section 41 and Schedule 5, paragraphs 7-9 of the Procurement Act 2023.

Planning Information

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.
