Southsea Coastal Defence Scheme — Construction Contractor
Portsmouth City Council the “Council” in collaboration with the Eastern Solent Coastal Partnership (ESCP), is seeking to appoint a major coastal defence contractor to deliver a significant programme of works to provide new improved flood defences at Southsea seafront.
The Council estimates that delivery of the scheme in its entirety may cost in the region of 95 000 000 GBP — 110 000 000 GBP.
Whilst the Council cannot commit to a firm programme at this point a target date for start on site is March 2020.
The Scheme divides Southsea frontage into 6 frontages which will be built in phases. Based upon the scheme envisaged within the planning application the Council forecasts that construction across all 6 frontages may take approximately 8 years to complete.
The Council is targeting to have secured the successful partner contractor by 6.9.2019. Application is via completion of a Supplier Status Questionnaire (SSQ) and associated documentation which must be submitted by 24.5.2019 (14:00).
Southsea is situated on the Southern coast of Portsea Island and is at significant risk of coastal flooding. Modelling has shown a present day 0,5 % Annual Exceedance Probability (AEP) (1 in 200 years) flood event would directly or indirectly affect 8 077 residential properties in the Southsea area, exposing 4 114 residential and 704 non-residential properties to inundation from coastal flood waters. For further information on the scheme, please visit: https://southseacoastalscheme.org.uk/
The Council estimates that construction cost of the scheme in its entirety may cost in the region of 95 000 000 GBP — 110 000 000 GBP. An Outline Business Case (OBC) for the Scheme was approved in 2017 to provide funding for the development of the pre-construction stage. The project is currently in the “Principal Design” Stage (RIBA Stage 3), which has developed the concept design into a planning level design solution. Following extensive public consultation the Council is on target to submit a planning application in May 2019. The funding for the construction stage of the project is dependent on a Full Business Case (FBC) for approximately 95 000 000 GBP being submitted and approved by the EA, Defra and HM Treasury. The principal design has been priced which highlights a funding gap of approximately 20 000 000 GBP.
Whilst the Council cannot commit to a firm programme at this point a summary draft construction programme is provided below with a target date for start on site during March 2020.
— Frontage 1: March 2020 — April 2021,
— Frontage 4: April 2021 — October 2022,
— Frontage 3: April 2022 — October 2023,
— Frontage 5 and 6: October 2023 - October 2025,
— Frontage 2: October 2025 — April 2027.
The contractor will be required to work with the Council on a 2-stage open book basis with Early Contractor Involvement (ECI) provided as the first stage. It is envisaged that the contractor will be secured to deliver the works under an NEC4 Engineering Construction Contract (ECC) Option C with X22 (ECI) on a build only basis, however this is currently under review and will be defined within the tender pack. The Council will require the contractor to immediately engage in ECI activities in partnership with the Council and its appointed designer to assist the delivery of the first frontage.
The Council will execute this procurement process in accordance with the “Restricted Procedure” as set out within the “Public Contracts Regulations (2015)” which encompasses an initial shortlisting phase prior to inviting tenders from the shortlisted contractors. In the interests of managing bidding costs for all parties the Council envisages shortlisting 3 and, in the event of minimal differences in scores, a maximum of 4 contractors only to take part in the tender stage. The Council will run the procurement process in line with the following programme:
— issue SSQ: 23.4.2019,
— bidders day: 1.5.2019,
— SSQ return: 24.5.2019, 14:00,
— issue tender to shortlisted contractors: 10.6.2019,
— tender returns: 5.8.2019, 14:00
— award: 6.9.2019.
As stated, application is via completion and submission of the SSQ and associated documentation which can be obtained from the Council's InTend e-sourcing solution using the following address:
A bidders day will be held on Weds 1.5.2019, 9:30-15:30 at Portsmouth City Council and Southsea seafront. Further information and joining instructions are contained within the SSQ documentation accessible via InTend.
The term of the contract cannot be accurately defined at this point and will be determined by completion of the scope of work, however based upon the scheme envisaged within the planning application and the division of Southsea into 6 phased frontages, the Council forecasts that construction activities may take approximately 8-10 years to complete.
In the interest of managing bidding costs for all parties the Council envisages shortlisting 3 and, in the event of minimal differences in scores, a maximum of 4 contractors only to take part in the tender stage. The criteria is stated within the “Project information and instructions to applicants” document accessible via InTend: https://in-tendhost.co.uk/portsmouthcc/aspx/home
The Council also reserves the right to alter the appointment of the contractor to a design and build basis either in full or in part over the term of the contract, subject to the agreement of both parties.
Should termination occur at any point during the contract term the employer reserves the right to:
— engage the contractor ranked 2nd place from the original tender evaluation scoring. In the event that the 2nd placed Contractor does not have capacity and / or terms cannot be agreed the employer may seek to engage the next ranked Contractor and so forth,
— undertake a competitive tender process restricted to the contractors who were shortlisted via the original OJEU Contract Notice and SSQ Evaluation.

Section IV: Procedure
Section VI: Complementary information
In summary, the core objectives of the scheme are as follows:
— to reduce the risk of coastal flooding and erosion to all properties and infrastructure within the Southsea flood cell,
— provide a minimum standard of protection of 0,5 % AEP (1 in 200 year) for the scheme frontage against flooding and coastal erosion for the next 100 years, including for climate change effects,
— identify and exploit opportunities for enhancement of the wider realm,
— incorporate environmental enhancement initiatives where possible.
In summary the scope of the activities the successful contractor may be required to undertake, although will not be limited to, is as follows:
— early contractor involvement activities and input into the detailed design,
— cost development and forecasting,
— programming and phasing,
— surveys and enabling works,
— subcontract/supply chain engagement and involvement,
— obtaining licences to work not obtained by the client,
— construction works,
— construction interface with stakeholders,
— traffic management, logistics and site management,
— defects management,
— further maintenance activities if required.
In the event that the contractor appointment moves to a design and build basis then the scope of activities will expand accordingly.
During the procurement period, and especially during the tender stage, the Council will allow for extensive 1-1 consultation with contractors to provide for effective clarification and discussion of approaches.
The Council is currently seeking tenders via a separate procurement process for the provision of detailed design services with contract award targeted for 17.6.2019.
Whilst the Council is procuring and managing the design and works contracts separately all parties will be required to work together in partnership on the project, which may be incorporated into the contract utilising X12.
