Strengthening of Grand Hyatt Athens Hotel

Project description

Client: AKTOR SA
Location: AKTOR SA
Year: 2018

Grand Hyatt Athens Hotel, 5* and 310 rooms, is the 3rd “Grand” in Europe and opened its gates in August 2018. At the same building was operating for more than 30 years the Athens Ledra Marriot Hotel. The building was constructed at the beginning of the 1980’s and has 12 levels (3 underground and 9 above ground level), while its total surface area is approximately 30.000m2.

Tasks description

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).
