“Bulgari” Hotel

The improvement work was aimed at achieving an increase in building safety. The structural design, following structural investigations and the consequent design of the works identified by the architectural and plant design, aimed to improve the performance of the existing structures downstream of the planned interventions required by a different use of the interior spaces, which, therefore, involved a series of punctual operations on the vertical structures: Reduction of load-bearing masses by replacing brick partitions with drywall and all “heavy” screeds and fills above attic with lightened materials; Anti-deflection interventions on soffit floors; Maintenance of the existing system of masonry taps and structures, providing some openings and closures in the masonry taps to rationalize and homogenize the portions discharging to the ground; Attic interventions, on the ground floor a swimming pool was designed, so it was necessary to demolish and rebuild the floor slab on the ground floor  to make one suitable to support the new design loads. Some slabs, unsuitable to withstand the new design loads, were entirely replaced by lightened concrete slabs; Seismic improvement works – reinforcement of wall males; Seismic improvement works – reinforcement of terrace walls and parapets; Foundation works, in the foundation the formation of micropiles by drilling was planned for the realization of the foundational works of the new structures, so as to reduce any differential subsidence.

The BIM techniques and methodologies applied to the job order made it possible to optimize the structural design by enabling integral and integrated management of this complex work through the creation of parametric three-dimensional models of the various disciplines to support all phases of the building process for more efficient analysis and control than traditional processes.
