Roofboxes for New OUH

When planning and practice go hand in hand

On the construction of Nyt OUH in Odense, installing large roofboxes above the elevator shafts has been a special task for almost a year and a half.

From the initial considerations of lifting strategy to the final precise placement on the roof, the project has been characterized by thoroughness, technical insight and a strong focus on safety.

One big lift instead of many small ones

In the early planning, a key question arose:

Should the roof boxes be mounted in individual parts on the roof?
or assembled on the ground and lifted in one piece?

The choice fell on gathering them on the ground.
This resulted in better working conditions, higher quality in the assemblies and a more controlled process.

One big lift rather than many smaller ones in height.

The design was adjusted

During construction, it became clear that the original design was not suitable for lifting. Approved lifting points were not included.

The design was therefore changed and documented lifting points were incorporated, which could be calculated and approved by engineers.

BMS was then involved in the design phase to advise on correct hooking, so that solution and execution are consistent in practice.

The weight was verified.

To ensure correct dimensioning, the most critical units were check-weighed with a dynamometer.

Based on the actual measurements, the solution was:

450 ton mobile crane
Tilt and 70 meter lattice boom
134 tons of ballast

This provided the necessary range and safety margin.

Five setups. One on the centimeter.

The task required a total of five setups.

One of them took place between two footbridges and without affecting the operation of the light rail. Here, work was done down to the centimeter. Planning, measuring and coordination were crucial.

And it worked.
