The New Storstrøm Bridge - Construction Tolerances and Precast Structures Installation Challenges

The construction of the Storstrøm Bridge faced and is facing a number of challenges, to ensure the alignment with design assumptions and project requirements. The main constraints related to tolerances and quality requirement are hereby described together with the strategy implemented to execute works. From the positioning of precast foundations to the erection of the girders a number of constraints pose a challenge to the general contractor (SBJV) since their fulfillment is crucial to ensure that the bridge performance standards are met, the construction program is followed and works disruption does not occur. The geotechnical settlements represent a particular challenge since the natural uncertainties related to their calculation require SBJV to adopt solutions that can accommodate any deviation from the predicted ones. In light of the above, a crucial role is played by advanced planning risk management and monitoring during construction operations.
