Invitation to Tender

Sluice Restoration

Invitation to Tender for the provision of a Contractor for the 2 Seas Interreg Funded Project:-

The Climate Resilient Community based Catchment Planning and Management, or the “The Triple C project”


Contractor Requirements Overview

A qualified contractor is required for a sluice restoration project in Cothelstone, Somerset through an Interreg funded project for the Farming and Wildlife Advisory Group South West Limited (FWAG SW).

The following gives a background to the project and the requirements that the contractor needs to meet to be eligible to tender for this contract.


About FWAG SouthWest

FWAG SW is a registered charity representing the region's farmers and landowners in the delivery of wildlife conservation and resource protection.

FWAG was first established as a charity in the 1960s by a group of forward thinking farmers who saw that the environment was an important part of a successful farming business. FWAG SW shares this vision today and acts to:
“promote and enhance the conservation of wildlife, the environment and the landscape in relation to modern agricultural needs.”


Territorial Co-operation Programmes

European Territorial Cooperation (ETC), better known as Interreg, provides a framework for the implementation of joint actions and policy exchanges between national, regional and local actors from the 28 different European Union Member States. The overarching objective of European Territorial Cooperation (ETC) is to promote a harmonious economic, social and territorial development of the Union. Interreg is built around three strands of cooperation: cross-border (Interreg A), transnational (Interreg B) and interregional (Interreg C). The funding is provided by the European Commission and the Programmes are managed by Member States.

The Interreg 2 Seas Programme is a European Territorial Cooperation (ETC) Programme and therefore an integral part of the European Union’s Cohesion Policy. It promotes cross-border cooperation between the coastal regions of 4 Member States: France, England, Belgium/Flanders and the Netherlands. The Joint Secretariat for the programme is based in Lille, France.

The Climate Resilient Community based Catchment Planning and Management, or the “The Triple C project”, falls under the Adaptation to Climate change strand of the Interreg 2 Seas Programme.

FWAG SW (The Beneficiary) is a partner in the project, with Somerset County Council taking the role of Lead Partner. FWAG SW’s role in the project is to develop, in cross border cooperation, a method for reducing flood risk and erosion through a novel catchment based, collaborative approach. FWAG SW will co-create and implement a range of climate adaptation measures (creating networks, demonstration plots, field trials, workshops) in the flood prone catchment of the River Parrett, Somerset for the wider public benefit.

The project funding will not be affected by the Brexit negotiations or our exit from the EU.


Sluice restoration background

We are proposing to restore an old sluice gate, located in the village of Cothelstone, Somerset. The old sluice that once controlled the water levels of a man-made pond has been damaged due to erosion under the sluice structure. The structural stability and effectiveness of the old sluice has been compromised, and as a result the pond is not retaining winter water levels. We are proposing to demolish the old sluice and re-build a new one in its place in order to restore the ponds attenuation capacity.



Design plans

A civil engineer has assessed the site and drawn up plans for the demolition of the old sluice and plans for the new sluice. Additionally, there are plans for a footbridge over the new sluice. Please see the design plans of the demolition and installation. Below is a description of the work that is required:


  • Removal of surrounding tree stumps
  • Existing pedestrian bridge to be removed and disposed of
  • Stone wall surrounding the old sluice needs deconstructing and stone saved for possible re-use
  • The historic weir structure deconstructed, and stone saved for re-use

Design plans of the demolition are detailed in the Demolition Plan PDF.

New sluice construction

  • Excavation for groundwork and new channel
  • New stone-faced retaining wall, using reclaimed stone from demolition of existing historic wall and filling with concrete
  • Low level valve (for draining of pond) located close to bridge for access to handwheel to be installed
  • Install steel RSJ frame for timber stop logs
  • Banks of approach in need of protection to reduce/prevent scour using cellular confinement (geotextile)

Design plans of the construction of the new sluice are detailed in the Proposed Arrangement Plan and Sections PDF.

New pedestrian footbridge

  • Install bridge and handrails as detailed in the design plans

Design plans of the construction of a new pedestrian footbridge are detailed in the Bridge Detail PDF.

Access to the site is shown in the Location Plan PDF.


Skills, knowledge and previous experience

We are looking for the following skills and experience:

  • Experience of reading and implementing technical drawings
  • Experience of delivering earthwork schemes that are environmentally sensitive
