[Ulster Wildlife Trust](https://tendernation.io/buyers/ulster-wildlife-trust) Estimated value £26,667 Published 23 Aug 2022 Deadline Closed 20 Sept 2022 ## Who can bid - Small contract value Valued under £135,018 including VAT, the lowest Procurement Act threshold for goods and services. - Open procedure Anyone can submit a full tender; there is no shortlisting stage. ## About this tender Ulster Wildlife is seeking to appoint an experienced contractor to source and obtain PVCu plastic pile sheeting (a full specification is included in ITT), transport these materials to Claragh and Tully Bogs and install them at marked locations. There are a total of 145 dams to be installed in total as part of the contract. 128 of these are on Claragh Bog and 17 of these are on Tully Bog. The 145 standard plastic dams will be required to span a minimum width of 1.5m which will require approx. 5 piles per dam depending on pile dimensions. These piles should be standard Z ribbed or box format in profile with tongue and groove fittings at either side. Each pile must be a minimum of 1.5m in length. Plastic piling should be PVCu plastic and black or grey in colour. The location of each dam will be marked with a coloured flag on site. Access to a mobile mapping service will be provided to the successful contractor so that they can view the locations of the dams in the field. Because of the very fragile nature of these raised bogs, no machinery access is permitted at these sites with the exception of low ground pressure or tracked machinery, e.g. Argocat type vehicle or tracked dumper. Installation should follow best practice guidance outlined in the Raised Bog Restoration Guidance Note (Mackin et al 2017). No equipment or materials are to be stored on the bog but materials could be stacked at the woodland edge.
