Bouygues Batiment International
together with their modular construction laboratory Dragages Singapore,
completed the construction of the 140-m Clement Canopy buildings in Singapore.
With its completion, the building is now the holder of world’s tallest modular
buildings title, previously held by George Street, a 135-m tower erected
by Tide Construction in Croydon, England.

The 40-storey Clement Canopy is a housing project
situated on the heart of a residential and student district in Singapore.
The two-tower structure, made up of 1,899 modules, was designed by local
architectural firm ADDP Architects and houses 505 two-, three- and four-bed
apartments, with a swimming pool complex at the base.

Bouygues Bâtiment International’s head of modular
construction Aurélie Cleraux said that each of the 1,899 modules was around 85%
finished off-site, before being transported and assembled onsite.

“The module’s structures were precast in a yard in
Senai, Malaysia, then a factory in Tuas, west Singapore, carried out the
fit-outs including painting, windows frames and glazing, doors, wardrobes and
MEP (mechanical, electrical and plumbing) to a nearly finished stage,” revealed
Aurélie Cleraux,

He added that upon arrival at the site, the modules
were stacked and installed at the same time the concrete core was built in a
carefully choreographed sequence.

The team embarked on this challenging mode of construction due to the many benefits it offers. First, by industrializing and building 50% of the project offsite, loss of time due to poor on-site weather conditions are eliminated. Secondly, each module can be manufactured under strict quality control and defects can be managed prior to handover. And lastly, it is more eco-friendly in that it increases onsite waste management.  According to Cleraux, this method enabled them to reduce waste onsite by 70% and around 30% offsite with a central materials and logistics platform.
