\nWhile several large construction firms have embraced technological advancement, such as the use of prefab technology, as an opportunity, most small and medium-sized enterprises (SMEs) are still resistant to change, reported The Straits Times.
\n\u201cConventional construction is facing many challenges. We knew that the (foreign worker) levy was going up and that the Government\u2019s direction was towards work productivity. So, we saw an opportunity to move forward,\u201d said Johnny Lim, executive director at Teambuild, one of the early adopters of prefab technology here.
\nIn 2013, a simulations run by Teambuild on some residential projects showed significant savings in time and manpower, even as the technology cost about 20 percent more compared to conventional methods.
\nNow, the cost premium has shrunk to less than 10 percent as the technology matured.
\nChiang Kian Hong, project director at Tiong Seng, noted that the challenges posed by cutting edge technologies may be overcome with careful technical planning and design.
\nIn fact, Teambuild set up a wholly owned subsidiary in 2013 that would build smaller prefabricated components, while Tiong Seng began building its own (prefabricated prefinished volumetric construction) PPVC capabilities in 2014.
\nMeanwhile, small contractors \u2013 which lacks the financial capacity to build on their own prefabrication modules \u2013 are still doing things the old-fashioned way.
\n\u201cWe still have to look deeper into PPVC and how much it will cost us,\u201d said Joseph Liew, general manager at GA Construction.
\n\u201cThe key concern is if we invest in technologies or hardware, can we use it in all our projects? Or will it become a white elephant?\u201d
\nRelying on external fabricators, on the other hand, would mean sacrificing a significant portion of the contract fee. \u201cIf precasters do most of the work, what is left for us other than hoisting and assembly?\u201d lamented Chong Tong Construction director Gwee Sung.
\nLiew and Gwee said the cost of PPVC adoption is too great for SMEs \u2013 at around 20 percent of their contract fees.
\nAnd while GA Construction spent around S$20,000 on hardware to try the building information modelling (BIM) \u2013 a virtual design system \u2013 this year, the firm is yet to implement it.
\nThis comes as a complete BIM adoption would involve a six-figure investment as well as \u201ca change of mindset\u201d of their staff and other sub-contractors, said Liew.
\n\u201cConversion also requires us to pluck manpower out from our operations \u2013 some diploma courses stretch for a few months.\u201d
