This is amazing.

However, BCA also notes that PPVC currently attracts a cost premium of just under 8% compared to.reinforced concrete construction.

, driven by a range of factors including comparatively low supply and demand.. Singapore has shown a great commitment to achieving the advantages of DfMA but PPVC has been more successful on some projects (and some types of project) than others.A local mindset has been established that equates PPVC with Design for Manufacture and Assembly at the expense of alternatives.This is starting to change with the government and private sector looking at other DfMA solutions such as panelised lightweight construction and CLT (cross-laminated timber), both of which have been successfully used in Singapore.

However, local industry discussion of DfMA remains dominated by the idea of standardised PPVC modules being stacked up to form finished buildings..The ongoing struggle to deliver PPVC cost-effectively in Singapore has an increasing degree of urgency.

The disproportionate impact of COVID-19 in Singapore’s foreign workforce shows the need to drive greater productivity while reducing over-reliance on foreign labour is more urgent than ever before.

But the big question is, ‘What next?’.When projects can take four to five years to realise, there might be a tenfold increase in rack density within that lifetime, creating a significant dilemma of what to build and how to pivot..

The move from air-cooled to liquid-cooled solutions is key.However, liquid cooling topology can be more complicated and expensive, so the trajectory for take up of this technology is still evolving.. Another disparity in scales arises between rack density and cooling technology infrastructure.

While density is increasing exponentially, cooling technology is not.You could achieve 10x as much density in a given data hall footprint, but the external mechanical and electrical plant will be 10x bigger.
