Invitation to Tender: Viewing Tower – Design and Build

November 12, 2019

Note: Please be aware that the link on this page will take you to third-party websites.

We are offering a design and build contract for the roofed interpretation space – this will take the form of a Viewing Tower. We don’t have planning permission yet so we are proposing a two phase contract;

  • Phase 1 to agree the design; prepare drawings for the planning application and deal with any requests for further information.
  • Phase 2 – pending successful planning outcome – construction of the viewing tower.

This will include:

  • Reviewing the technical feasibility
  • Ground investigations (if required) to determine structural requirements
  • Preparation of concept drawings for the project team to agree final design
  • Preparation of design drawings for planning application
  • Assisting the project team with any technical enquiries or requests for further information during the planning application / review / consultation process
  • Mobilising contractors to build the tower
  • Constructing associated access boardwalk
  • Being responsible for any H&S / CDM regulations.

Materials and Final structure

We would expect the materials to be sympathetic to the area. Ideally the tower will be maintenance free and vandal proof.

A large consideration will be avoiding damage to the SAC and Ramsar site.

As a guide we anticipate the final structure to be no higher than 5 metres.


Our preferred location is on the edge of Whixall Moss NNR, within the SAC and Ramsar designation and adjacent to the canal. The all ability trail finishes here and we recommend a short section of boardwalk to enable access off the all ability trail. The peat depth in this area is approximately 4m.

A site visit for interested parties will be held on 26th November 2019 at 10.30am.


As a guide we expect this to cost in the region of £45,000.


All quotes should include the project reference – LIFE15/NAT/UK/000786 – Marches Mosses BogLIFE Project.
