Enexis: Earthquake-proof redesign without delay
VORM4 participated in the construction and revitalization of the Enexis building in Kolham. We identified structural risks without original production drawings and integrated earthquake loads directly into the model. Thanks to our approach, the design could be realized safely, efficiently and without delay.

Construction without original drawings
Important production drawings were missing during the revitalization of the existing building, and the reinforcement at critical construction points was unknown. There was also hardly any overcapacity in the existing structure, while architectural and installation requirements were increasing. At the same time, earthquake resistance was required. The customer was looking for a safe, future-proof design that could integrate all these obstacles without delay or major demolition.
Smart scan analysis & integrated design
VORM4 carried out detailed scan analyses and drilling to identify hidden reinforcement. The entire design was linked to an analytical model that also calculated earthquake loads. With this approach, we were able to design integral, safe solutions with minimal impact on the existing building and maximum feasibility for the contractor. Our output was so complete that the contractor could start working with it immediately.

Prefab floor analysis
Due to the absence of production drawings, a smart solution was chosen without recalculating floor elements.
Draw up constructive calculations
Based on the existing situation and new plans, VORM4 carried out extensive calculations.
Stability analysis and reassessment
All critical points were checked, using concrete scanners and local drilling.
Stability analysis and reassessment
For the existing parts, it was recalculated whether they met the new requirements.
Integrate Earthquake Analysis
The structures were calculated for earthquake resistance within one analytical model.
Delivery of design documentation
All designs and calculation results have been handed over to the contractor.
Control during construction
During the execution, VORM4 checked whether the work was realized in accordance with the design.
Projecten die innovatie en efficiëntie aantonen
Elk project laat zien hoe we complexe uitdagingen vertalen naar efficiënte, toekomstbestendige oplossingen met de nieuwste technologieën.

VORM4 uses advanced non-linear time domain analysis to make buildings in Groningen earthquake resistant, validated through intensive tests.
