This project is a new eco-district to meet environmental challenges and promote energy autonomy, including 23,700 m2 of offices, 200 housing units and 3,800 m2 of commercial space.

Stirnimann’s solution included one Potain MDT 308 and three MDT 389 top-slewing tower cranes equipped with cameras, the Potain Top Tracing 3 interference system, the new Potain connect telematics system, and aviation lighting.

The cranes were configured as follows:

• Crane 1: MDT 389 on sealing feet (P800) with a 75.02 metre hook height and 50 metre reach
• Crane 2: MDT 389 on a 10 x 10 m chassis (JM850) with an 89.4 metre hook height and 60 metre reach
• Crane 3: MDT 308 on a 6 x 6 m chassis (V60) with a 58 metre hook height and 55 metre reach
• Crane 4: MDT 389 on a 10 x 10 chassis (JM850) with a 94.3 metre hook height and 60 metre reach

The Potain MDT 389 has a maximum load capacity of 16 tonnes and 3.3 tonnes at the end of the 75 metre jib. However, it will primarily handle loads of 11 tonnes at 30 metres and 6 tonnes at 55 metres.

“Several factors make this a complex and unique project with building heights reaching 80 metres and the location of two towers close to the SBB railway. For these reasons, we needed a reliable partner in whom we could have total confidence in terms of skills and professionalism. The understanding with Stirnimann employees was the icing on the cake,” said Florian Lamy-Rousseau, project manager at Implenia.

Michel Jérôme, technical manager at Stirnimann, added: “Implenia and Stirnimann have worked hand in hand to meet the project’s diverse requirements. The collaboration in designing and assembling the cranes has been a pleasure.”

The cranes will operate daily from 7 am to 6 pm, and the project is estimated to last between 24 and 30 months.
