We love and care for your canals and rivers, because everyone deserves a place to escape.

Documentation, monitoring & completion

Pre-works documentation and your Construction Proforma

We will need to review your DCNA and DCA submission prior to you commencing works to ensure you have satisfied the criteria. Whilst it is helpful for us to understand your full construction programme for each stage, the key elements we are concerned with are identified below. We encourage you to liaise with us as you develop your scheme so that we can agree solutions with you as you progress. For more information on working with us, the information we require to make our appraisals and our contractual requirements, you should refer to the Our Application Process section of this website.

  • Excavation of the void
  • Lining system
  • Edge details
  • Earthworks
  • Sealing / site isolation arrangements
  • Connection to our network
  • Bank protection to the adjacent waterway (if required)
  • Construction of towpath over-bridge (if required)
  • Statutory approvals

Method statement

Your method statement should demonstrate how you will ensure that the integrity of the existing waterway is maintained. This should include the detail of how you will excavate the void and construct your scheme, and examine the operational impact of the construction of the connection to our network. The Method Statement should also describe in detail how the connection to the waterway is to be undertaken in dry conditions.

The Method Statement should deal with issues relating to the prevention of construction site pollution (and pollution of the adjacent waterway), site safety and, where constructed on the towpath side of the waterway, how the towpath will be diverted around the construction works and adequately protected. Because of the age of our structures, vehicular loading and the use of craneage will not usually be permitted on the towing path or immediately adjacent to the off-side waterway wall/bank.

The provisions of the Construction Design and Management (CDM) Regulations www.hse.gov.uk apply to the construction of mooring schemes, including the need to segregate the construction site from the public. Public access from the adjacent waterway may be a particular issue in this respect. Methods of working (and risk assessments for works directly affecting Canal & River Trust) will need to be developed in accordance with the CDM regulations

Construction programme

This should provide the detail of the stages and timing of the construction. This will need to identify issues associated with the need for a stoppage (refer to the Construction - Timing and canal closures page of this website), the ability for us to pass any water through a complete stoppage, the programming required to fit in with our National Stoppage Programme and also the identification of any additional consequential costs arising.

The programme should allow a minimum of 14 days for the required stilling test (test of water-tightness). Refer to the Design-Construction Performance Criteria - The stilling test page of this website.

You are advised to build in adequate time for materials sourcing and testing.

Detailed structural plans and design certificates

The relevant detailed structural plans and design certificates should be included in the Detailed Design & Construction Phase Submissions. Where information is not received prior to works being undertaken, Canal & River Trust may request the applicant to prove the integrity of the works by providing information outstanding, evidence of insitu testing or Canal & River Trust may request retrospective testing be carried out to confirm compliance with design requirements and Canal & River Trust performance specification.

Our appraisal of your Detailed Design & Construction Phase Proforma

Our review of your Detailed Design & Construction Phase Proforma will take the form of a report & letter.

Works affecting our waterway cannot proceed until we have confirmed that the following conditions have been met:

  • DCNA and DCA Submission requirements have been satisfied
  • Statutory approvals have been granted
  • You have entered into a Network Access Agreement and any other necessary legal agreement with us (refer to the page Our Application Process - Legal agreements)

We will continue to liaise with you after the approval and during construction for example at a pre-works meeting, site inspections etc.

Construction monitoring

Prior to starting any construction activity that directly affects the navigation, it will be necessary to hold a pre-commencement meeting in order to satisfy Canal & River Trust that all safety, technical, operational and environmental issues have been adequately addressed.

During the course of the construction of your mooring scheme regular site visits by our staff will be required. We will wish to make inspections at the key stages to verify the actual site conditions and to confirm that construction is carried out in accordance with the plans in your Detailed Design & Construction Phase Submissions (DCNA & DCA).

As stated earlier we are particularly concerned with excavation of the void, lining, edge details, earthworks, site isolation arrangements, connection to our network, bank protection to the adjacent waterway (if required) and construction of towpath over-bridge (if required).

Where a liner is used, you will have to satisfy Canal & River Trust that a suitable Quality Control regime is adopted throughout the construction phase to demonstrate the integrity of the completed works.

Arrangements for inspections will need to be made with the appropriate staff, usually our local engineers with whom you will have been liaising.

In the event of any unforeseen conditions occurring on site during the construction, for example the discovery of springs under the excavated basin resulting in the need for a drainage blanket to be installed, you may need to modify your specification for the works. We will endeavour to agree an appropriate solution with you as quickly as possible.

Post-works documentation and completion procedure

On completion of the works, and following a successful stilling test, a 'completion statement' will be issued by Canal & River Trust to the applicant.

Any relevant operating arrangements for the mooring site which affect our operation of the waterway will be recorded to form the basis of ongoing operational liaison. Where there is any interface with our operating equipment, the relevant procedural and technical protocols will be documented. When the works have been completed to our satisfaction, we will issue a letter to confirm this and will initiate payments as detailed in the Network Access Agreement.

You may also wish to refer to the page Your scheme - Opening and operating of this website which contains more information for when your site is open.
