This tender is currently in the planning stage, with the engagement end date set for 2nd November 2020. The aggregate is to be supplied to various locations in East Sussex, specifically between Newhaven and Lewes. Interested suppliers should ensure they meet the material specifications, which demand high-quality Kentish Ragstone suitable for tidal riverbank revetments, as well as having the appropriate planning permissions in place. This tender presents significant opportunities for businesses involved in the supply of construction materials, particularly those specialising in natural stone aggregates. Companies with proven capabilities in sourcing durable, environmentally compliant materials, particularly those from local quarries, will find their expertise highly relevant. Additionally, small and medium-sized enterprises (SMEs) are encouraged to participate, leveraging their agility and local knowledge to meet the specific requirements of this contract. ## Notice The Environment Agency is seeking early engagement with suppliers for the supply of natural stone aggregate for embankment repairs to the tidal River Ouse embankments in East Sussex between Newhaven and the A27 (near Lewes). The banks of the tidal River Ouse were raised in the fifties and the exposed face was protected from scour at high tide by a revetment know as pole wharfing. The revetment consists of chestnut stakes and woven chestnut poles retaining limestone cobbles. Approximately 1,000 - 2,000 tonnes of aggregate each year (from 2015 to 2024) are expected to be used for polewharfing and as gabion fill material. The average annual quantity of aggregate is likely to be around 200 tonnes however this figure could vary from year to year as the work is dependent on the condition of the embankments. Work is typically restricted to between April and September to coincide with the favourable ground conditions (although emergency repairs may be required outside of this period). The work is necessary to enable the Environment Agency to comply with its legal obligations under the Newhaven Navigation Act 1847 and has resulted from the approved River use to Seaford Head Coastal Defence Strategy. Material Specification: The aggregate supplied for the Contract will need to match with the existing natural stone aggregate already in place along the tidal River Ouse embankments which is Kentish Ragstone, a sandy limestone aggregate. All material supplied under the Contract must be suitable for the intended purpose (as a tidal riverbank revetment or gabion stone). The material shall be hard quarried rock, extremely durable, frost proof and non-degradable. Please note, The detailed aggregate specification, the Environment Agency will only accept interest from potential suppliers who can evidence the supply of the raw aggregate material that can meet the specification in Table 1 below.
