Hawaii Looks to Singapore for Innovative Housing Solutions

A housing delegation from Hawaii explores Singapore’s prefabricated construction methods to address the housing crisis in the islands.

With tens of thousands of people in Hawaii in need of housing, the demand for affordable homes far exceeds the supply. In search of innovative solutions, a housing delegation from Hawaii recently visited Singapore to explore the use of prefabricated construction methods. Singapore-based company United Tec is pioneering a construction technique called Prefabricated Prefinished Volumetric Construction (PPVC), which promises faster, safer, and more efficient housing development. This article delves into the details of PPVC and its potential application in Hawaii’s housing market.

Prefabricated Prefinished Volumetric Construction: A Game-Changer in Housing Development

At the construction site on Ang Mo Kio Rise in Singapore, the housing delegation witnessed the groundbreaking PPVC method in action. Unlike traditional modular or prefabricated homes, which often require folding walls to create rooms, PPVC utilizes concrete boxes that are crafted off-site in a factory. These modules are nearly 90% complete before being transported to the building site, where they are assembled like interlocking Lego blocks. The delegation observed workers skillfully using cranes to stack the prefabricated boxes, creating fully finished apartments.

Rapid Construction and Increased Efficiency

United Tec, the Singapore construction company behind PPVC, claims that they can complete one floor of a building in just eight days, significantly faster than traditional construction methods. This accelerated pace could be a game-changer for Hawaii, where the need for housing is urgent. The recent Maui wildfires displaced around 7,000 people, and an additional 20,000 residents across the state struggle to find affordable homes. State Senator Stanley Chang, who led the delegation, believes that adopting modular or precast housing could help alleviate this housing crisis.

Overcoming Challenges and Maximizing Benefits

While modular construction offers numerous advantages, there are challenges to consider. Paul Watase of Mark Development Inc., an affordable housing developer in Hawaii, acknowledges the potential savings in financing and construction time that modular housing can provide. However, he raises concerns about the impact on the local labor force and unions. If modular housing undercuts the unions, the quality and reliability of the construction workforce may suffer. Additionally, the high cost of shipping materials to Hawaii could undermine the economic benefits of modular construction, making local production facilities essential.

The Path to a Housing Solution

Lawmakers in Hawaii recognize the urgent need to increase the housing supply across the islands. State Senator Stanley Chang emphasizes the potential of modular construction to expedite housing development. By building a new floor every six and a half days, Hawaii could see a significant improvement over traditional construction methods. However, the success of volumetric modular construction in Hawaii would depend on the establishment of local facilities for producing prefabricated rooms. This would mitigate transportation and production costs, making modular construction a viable solution for the housing crisis.

Conclusion: The housing delegation’s visit to Singapore has shed light on the potential of Prefabricated Prefinished Volumetric Construction (PPVC) to address Hawaii’s housing needs. With its faster construction time and increased efficiency, PPVC offers a promising solution to the housing crisis. However, challenges such as the impact on the local labor force and high shipping costs must be carefully considered. If Hawaii can establish local production facilities for prefabricated rooms, modular construction could revolutionize the housing market, providing affordable homes for the thousands in need. As the state grapples with this pressing issue, the adoption of innovative construction methods like PPVC may be the key to a brighter future for Hawaii’s residents.
