    Brief

    This contract involves the maintenance and renewal of small civil engineering waterworks such as weirs, inlet structures, and revetments. The focus is on efficiently and sustainably carrying out both planned and emergency work, with attention to collaboration, environmental impact, and social implications. For additional information, please refer to the tender document. The contract is estimated at €1,000,000 per year, excluding VAT: €850,000 for Lot 1 and €150,000 for Lot 2. Assuming a duration of two (2) years, with two one-year extensions, the total revenue is approximately €4,000,000. This estimate is based on annual budgeting of KOP projects, with costs projected based on historical prices and an assessment of future developments. An indexation margin has been added. The total estimate is divided between Lot 1 and Lot 2. For unforeseen circumstances, such as small civil technical maintenance, the estimate may reach a maximum of 150% of the original amount. The estimates for both lots form a single total budget, with mutual settlement allowed.
