For the Molenlei project on Meidoornsingel in Rotterdam, we realised the complete steel structure for the church tower. A project in which engineering, logistics and assembly came together closely.
Commissioned by Van Omme en de Groot Project Developers and Builders, we had previously carried out the steelwork for the care and church building. In this phase, the focus was on the church tower, the most striking part of the project.
The structure was fully produced in our workshop in Maassluis and largely made from heavy HEM profiles. All components were pre-processed, assembled, welded and finished by us before being transported to the coater for metal spraying and the application of a two-layer powder coating.
After preservation, the complete structure returned to our workshop for pre-assembly. With a length of approximately 20 metres and a total weight of more than 20 tonnes, this required a carefully considered approach. Because the maximum lifting capacity in the hall is 12 tonnes, we chose to assemble the church tower directly on the trailer. This allowed us to stay within the lifting capacity of our cranes.
Temporary support structures were used for transport and assembly to prevent deformation during lifting and transport. Verwaal Transport then transported the structure to Rotterdam, where the church tower was lifted vertically from the trailer using a mobile crane.
To enable precise assembly, special template plates were used during both the pouring of the foundation and the installation of the base plate of the church tower. This ensured that the complete structure aligned exactly with the cast-in anchors and could be positioned within the required tolerances.
Project details:
• Church tower length: approximately 20 metres
• Steel structure weight: more than 20 tonnes
• Fully pre-assembled in our workshop
• Carried out including temporary support structures for transport and assembly
After completion of our work, the church tower was further finished architecturally with, among other things, natural stone, cladding, church bells and a distinctive cross.
A technically challenging project in which preparation, collaboration and craftsmanship were central, and one we look back on with pride.
