SINGAPORE - An ambitious plan to upgrade the roofs of all Housing Board blocks has stalled due to a lack of local companies stepping forward to submit ideas.
Only two companies have put forth plans for the revamp - which could mean solar panels being fitted on rooftops across the island.
Neither of them met the requirements. Now, the HDB is once again calling for Singapore companies to bid for the project, which is expected to be test-bedded within a year.
Documents on the Next Generation Roofing System for Public Housing were first released last October.
Although no details of the two companies were available, industry watchers said the low take-up rate could be due to a lack of resources and local firms' fears over the potential risks involved.
The call for proposals was launched as part of the Public-Private Co-Innovation Partnership. This scheme seeks ideas from local companies in order to help the Government deal with the "many challenges and needs that do not have existing solutions".
The HDB needs to find a cost-effective way to upgrade the roofs of its 9,300 HDB blocks.
It wants to make sure they can shield residents from heat, prevent water from seeping in and possibly generate solar power.
