Electro work, which is not described in this contract, will be announced in a tender in spring 2019 as a separate turnkey contract K6 Electro. An option is included for Place A — Process 12.912 for transporting K6 Electro to this contract. See chapter A3 point 10.12 and chapter B3 point 7.3 for further information on the option. The provisional builders estimate for K6 Electro is NOK 210 000 000 excluding VAT. If the actual contract sum for K6 deviates from the estimate, the price of the option for transport will not be adjusted.
Lepsøy bridge will be announced with 2 equal alternatives, one with a cantilevered bridge (chapter D1 — Place B1B) and one with a steel box (chapter B1 — Place B1S) in the superstructure. Tenderers can choose which alternative they will submit a tender for. Tenders shall only be submitted for one of the alternatives.
