We received an abandoned building with integrated bearing structure. The situation was aggravated by moisture and “regulars” of the region. In cooperation with the prospective tenant, who was hesitant at first, we reached a techno-economic study of utilization of the building and presented it to the owner. Realizing, the owner, the opportunity to regenerate the property, he ended up to our proposal for cooperation and the work began. The challenge was great and the budget and time limited. Very specific need was the company not to stop its operation at all. New electrical infrastructure weak and strong currents (data & voice), new air conditioning, room safe, security systems and 16 hours working hours. Design had to meet the challenge of logistics smooth operation besides with the the seamless operation of data centre, upon which a network of 5,000 partners is depending.
