Since the 1970s, the manufacturing world has developed a supply chain system called Just In Time delivery. All parts would be delivered just in time and manufacturers did not have to incur cost in warehousing and paying ahead for parts that may not be used when the production volumes changed.
Now in 2023, with big data, with AI, improved communication and transportation, and all the knowledge and experience and things called smart cities, would Just In Time delivery or manufacturing be further improved? Without Just In Time delivery, there would be a lot of wastages due to over or under supply, warehousing and inefficient supply chain. Should this be a thing of the past especially in a tightly knitted city state like Singapore, with less than 6 m population and even lesser at about 3.5m in terms of citizens?
Just heard over the news, when it was proudly announced that citizens buying BTO flats only have a 3 to 4 years waiting time for delivery of their flats. With such a small population, with the monopoly in building HDB flats, with improved building technology, supply chain, automation, AIs, big data and calling Singapore a smart city, why is it so difficult to shorten the waiting time to build and deliver HDB flats to maybe less than a year, less than 6 months?
China can build a 40 storey building in less than a month using prefab, automation and advanced building technology. I have been watching the construction of simple one storey structure, with simple support beams, something quite similar to a hawker centre, and after more than a month, only a small part of the floor was laid, and a few steel pipe pillars were erected, joined by physically welding the steel frames and beams together. It looks like it would take weeks before it is ready to install the roof. And it would take many more weeks before the structure is finally completed. And there were about 20 foreign workers on site daily. Heard of a few hundred units of residential homes being built in a month in Africa by the Chinese construction brigade?
Oops, I digressed. Is Singapore a dumb city or a smart city? What kind of building and construction technology is being used, what kind of planning and management science, what kind of trained and talented workers? 30 or 40 years ago the waiting time for HDB flats were also 3 to 4 years. Today, it is still 3 or 4 years?
What a great improvement for a smart city with so many smart foreign talents! Is building flats for a small island population so complicated to plan and build that all the AI, technology, big data etc etc are unable to cope with and unable to improve on the delivery time?
What do you think?
