Replacement of the K53 Mühlenbach Bridge in Emsdetten: design and construction

Summary

The procurement covers the replacement of the K53 Mühlenbach Bridge in Emsdetten, including the design and construction of the required engineering structure. Work must start no later than 20 working days after award and be completed within 300 working days. The bidder must submit a bar-chart construction schedule with its offer, describe how the existing bridge will be demolished, and explain the proposed design, materials and construction methods for the substructure and superstructure. The bidder must provide at least three bridge-construction references from the last ten years, each worth at least €1.5 million net and covering the work from design planning through opening to traffic. The bidder must also name a qualified safety and health coordinator, a person responsible for work-zone traffic safety and a deputy, and a qualified specialist to install vehicle restraint systems. Evaluation assigns 70% to price and 30% to shortening the construction period; an offer 20% shorter than the maximum construction period receives the maximum acceleration score. Alternative offers are not permitted, but multiple independently awardable main offers may be submitted. The offer must include the required forms and priced bills of quantities in PDF and GAEB formats. During contract performance, the contractor must comply with applicable minimum employment conditions and ILO core labour standards.
