This project falls under the construction works industry category and is at the tender stage, with submissions due by 17 February 2022. The procurement process follows an open method, allowing participation from various suppliers. The contract is anticipated to commence on 1 August 2022 and conclude by 1 November 2022. This tender presents significant opportunities for businesses in the construction sector, particularly those specialising in habitat restoration and environmental works. Small and medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) would be well-suited to compete for this project, as it aims to enhance biodiversity and improve water management in the marsh habitat, thereby aligning with sustainability goals. Businesses with expertise in landscape construction, ecological restoration, and related engineering services are particularly encouraged to consider this opportunity for potential growth and collaboration with a reputable organisation dedicated to conservation. ## Notice To improve the habitat found at RSPB Old Hall Marshes we propose to carry out the following, we will use material generated from reprofiling existing footdrains to renovate existing crossing points around the reserve. We propose to install a Tilting weir (RSPB to provide) and finally renovate several small islands into one larger island and top with shingle. The works will ensure that we have increased compartmentalisation across the marshes, with finer and more water control. This will enable better management potential and the ability to be more dynamic with water levels. It will also mean that we have mitigated some of the potential impacts of climate change, as water will be better directed on site to critical areas. The newly reprofiled footdrains will create enhanced and new edges for breeding and passage waders including locally important numbers of lapwing and redshank. The new weir will allow the unrestricted passage of eels across the marshes and ensure better and more water control in addition to the renovated crossing points. The new and improved island will create new breeding habitat for the red listed and rare little tern, a designated species in the Blackwater estuary.
