Today’s public grand opening was the conclusion of our Technical supervision services during the remodeling of the Albert supermarket in Hradec Králové. Extensive remodelling was for a sales area of 2 300 m2 on two floors, including technological replacement and a new façade. With a focus on limiting operational interruption most of the interruptive works were performed after hours, but the reconstruction was segmented such that the project was executed 24 hours per day. The project was completed on time and with virtually no interruption of operation and handed over on time for unhindered operation.
