The Bayshore comprises two pairs of symmetrically located 30-storey towers with overhang roof crown features each linked by a 12-storey block, which accommodates 1,038 residential units with three swimming pools and includes one 9-storey block which housed the clubhouse, communal facilities and a 3-storey basement carpark.
This is the first high rise condominium in Singapore to utilise load bearing precast wall structure on the four 30-storey blocks for both the external and most of the internal walls which yielded flat and smooth finished surfaces. A total of 20,792 precast panels of approximately 700 different types were used for the entire project.
The precast components were prefabricated off site with the electrical conduits, openings and recesses for the M & E services incorporated and transported to the site based on the just-in-time principle for installation. The contractor adopted the jack-up form system for the construction of the corewalls comprising lift and staircase walls. Construction of the staircases in the core area was standardised using pre-assembled steel cage staircase system. To transfer forces between the precast components and ensure structurally sound connections, grouted and cast-in-situ connections were used. NMB Splice sleeve system was introduced to keep the joints between the wall to floor panel together and prevent them from separating. Between the wall panels, the vertical and horizontal joints were formed by high strength pressure grouting and sealed from outside to ensure water tightness.
The contractor was able to achieve a construction cycle of 10 days per floor with the above construction method and completed the condominium with excellent quality. This project was also one of the CIDB Buildable Awards winner in 1997.
