An Danmhairg – Sea wall construction work – Udbud af hovedentreprisekontrakt vedrørende forstærkning af Ballum Dige

Digelaget i Brede Ådalen is a local association responsible for maintaining and securing the dikes along Brede Å to prevent flooding of the adjacent agricultural areas and valley. The work of Digelaget i Brede Ådalen therefore often involves maintaining dike crowns and slopes to ensure stability against water pressure. In accordance with this, Digelaget i Brede Ådalen now wishes to strengthen the existing Ballum Dike with clay and sand along the stretch from Rømø Dæmningen and south to Vesterende, which totals approximately 7,500 meters. This work will also include excavation and creation of a lake area in connection with the extraction of the clay and sand deposits used for Ballum Dike. On this basis, Digelaget i Brede Ådalen wishes to enter into one construction and installation contract ("the Contract"), which will mainly include the following works and their main quantities:

1. Milling of the vegetation layer on approximately 18.5 ha of dike (on the existing dike slope, foreland and dike crown)

2. Excavation of 26.8 ha of vegetation layer and temporary deposition thereof on the existing dike slope, foreland, dike crown and on the back slope

3. Excavation from the existing dike, transport and incorporation of approximately 63,350 m3 of raw soil into the dike

4. Excavation from the existing dike and disposal of approximately 23,550 m3 of raw soil in the dike

5. Excavation from the lakes, transport and incorporation of approximately 182,250 m3 of clay

6. Replacement of the vegetation layer and seeding on the new dike profile, 26.8 ha. This is supplemented with the transport of vegetation soil from the lakes

7. The quantities of raw soil and clay necessary for the project are extracted by the contractor in connection with the excavation of new lakes close to the sub-project. The materials are transported to the dike and incorporated by the contractor. The contractor keeps the lakes dry in connection with the excavation work

8. Completion of the lake banks and restoration of affected areas around the lakes

9. Fertilization and seeding of all affected areas. All areas where work is to be carried out are located at Ballum in Tønder Kommune. The clay to be used for the reinforcement will be delivered as a client supply, the estimated value of which is approximately 15-16 million kr. However, the transport of the clay will be covered by the works associated with the Contract. In addition, a smaller supplementary purchase and delivery as well as laying of suitable stable gravel or crushed concrete for maintenance of interim roads and work roads from the excavation site to the dike incorporation sites will also be covered by the Contract. Digelaget i Brede Ådalen cannot provide electricity, but can be helpful. The works related to the actual dike construction must be carried out from March/April 2027 to October 2028 and may be carried out during the period from 04:00–18:00, provided that this does not conflict with other regulations, including the permit from Kystdirektoratet. Furthermore, it is expected that work on the excavation sites can begin approximately one month earlier, i.e. in February 2027. For the sake of dike safety, the contractor is obliged to pause the execution from October 2027 to February 2028, after which the work can be resumed. At the time of the publication of the tender, Digelaget i Brede Ådalen has not received final permission from Kystdirektoratet for coastal protection. The permit is therefore provisionally attached as an application and will be replaced by the final permit when it is received. Digelaget i Brede Ådalen expressly reserves the right to cancel the tender if final permission is not obtained. Digelaget i Brede Ådalen also expressly reserves the right to wait to enter into a contract with the winning tenderer until final permission is obtained. Furthermore, Digelaget i Brede Ådalen expressly reserves the right to cancel the tender if Digelaget i Brede Ådalen does not receive the necessary financing from Tønder Kommune for the implementation of the project, and Digelaget i Brede Ådalen also expressly reserves the right to wait to enter into a contract with the winning tenderer in this case. Digelaget i Brede Ådalen has not divided the tendered construction and installation contract into sub-contracts, as Digelaget i Brede Ådalen assesses that such a division will result in a number of impractical technical, legal and practical interfaces with the consequent risk of increased transaction costs and risk exposure for Digelaget i Brede Ådalen (hereinafter "Client"). In particular, the documents work description for workplace, work description for traffic-regulating measures, Asfalt - AAB-SAB-P, AAB-SAB-P SOS and AAB-SAB Earthworks contain a detailed description of the tasks that are covered by the Contract. Any reference to standards shall be understood as a reference to the mentioned standard or equivalent. If the tenderer does not meet the mentioned standard, but equivalent, the tenderer must document in the tender that the offered solution on the relevant parameters is equivalent. The tender is carried out electronically using the tender portal www.udbuddet.dk. The tenderer must therefore be registered as a license holder with www.udbuddet.dk. Registration can be done without cost. Questions regarding www.udbuddet.dk should be directed directly to www.udbuddet.dk via the support function, which can be found via telephone +45 7022 7007. No remuneration is paid for the tenderers' participation in the tender process. Tenderers are encouraged to conduct an inspection of the stretch where the reinforcement is to take place. This is particularly due to the fact that the construction and installation works covered by the tendered Contract are tendered as a fixed price. This means that the contractor's remuneration is not adjusted, regardless of whether the quantities stated in the tender list, which form the basis for the fixed price, turn out to be different during the execution of the work. This is also the reason why the Client can make the 3D measurements, which form the basis for the quantities in the tender list, available for part of the tender material.
