The Clement Canopy is a residential condominium located along Clementi Avenue 1. In its vicinity are three schools and residential blocks. The development has a Gross Floor Area of 50,200 m2, consisting of 505 dwelling units spread over two 40-storey blocks and a multi storey carpark with one basement floor. The basement floor, multi-storey carpark and first floor of the blocks are of conventional construction, while the typical floors from level 2 to 40 have adopted Prefabricated Prefinished Volumetric Construction (PPVC). 

The PPVC modules were designed as six-sided concrete PPVC modules. The weight of the modules ranged from 26 tons to 31 tons and were installed using two 48-ton capacity tower cranes. There were a total of 1,866 modules used in the construction of the two towers. The main contractor was able to install 10 to 12 modules per day with a floor cycle time of 7 days. The Clement Canopy is the world’s tallest concrete PPVC building. 

The adoption of PPVC at The Clement Canopy brought about many learning points in design, production and site works. Back in the design room, early confirmation of drawings and materials represented one of the major hurdles towards ensuring a smooth production cycle. Another of the early decisions to be made was the location of the heavy duty tower crane to determine the crane’s foundation and its tie-back to the main tower. This affected the overall structural design of the residential towers and modules had to be strengthened to cater for this additional loading. In addition, while quality of workmanship was improved as the bulk of architectural works were carried out in a factory controlled environment, strict site control and discipline had to be maintained to ensure minimal damages to the finishes. 

Overall, the adoption of PPVC has helped all stakeholders of the project in achieving shorter construction duration, higher quality workmanship, safer construction site and lesser disruptions to the surroundings schools.
