Construction of the new J Pavilion, a five-storey building with over 11,550 sq. m. of surface area. This new building is adjacent to the existing St. Mary Pavilion.
The second phase of work consisted in the extension of the emergency services pavilion (Pavilion K). The floor area of the emergency has been increased and two floors were added to the existing 2-storey building.
This second phases also included the extension of the B Wing whose work includedthe addition of an underground mechanical room and two floors of office space.
Special attention had to be taken with the designing and construction of the new foundations for the J Pavilion. Indeed, the ground was supporting at its maximum the existing weight of St. Mary Pavilion. Precautions had to be taken to limit the ground vibration during the extension, to prevent an eventual settlement of the existing structure. Foundations on screwed piles were used to transfer the new loads generated by the new building, to deeper soil layers.
Existing ground conditions and the necessity of deep excavation near the old existing building represented a rather delicate situation. Specific excavation procedures and soil retention were applied.
