As part of the general restoration of the building, several strengthening works of various elements of the load bearing structure were carried out at almost every story.
The works that took place were non-vibrating concrete cutting, shotcrete jacketing, strengthening with steel plates, strengthening with FRPs, steel structures connections on concrete elements with epoxy anchors and steel columns bases grouting, connection of existing and new concrete through dowels, and general repairs of load bearing elements.
The special features of the project concern the tight schedule (<3 months), the tasks that needed to be dealt with on various fronts, the limited working space (especially on the underground levels), the difficulties in access and materials handling (rebars reinforcement, shotcrete materials, etc.) and working in parallel with several other subcontractors.
ENKA executed the project successfully and on schedule, in perfect collaboration with the engineers and managers of AKTOR (contractor) and DIARCHON (construction supervision).
