POST OCCUPANCY EVALUATION (POE) OF PREFABRICATED PREFINISHED VOLUMETRIC CONSTRUCTION (PPVC) FLATS IN SINGAPORE

Abstract

The use of Prefabricated Prefinished Volumetric Construction (PPVC) in the construction of flats is no surprise to one. It is a construction method that has been discussed extensively in the past years to improve Singapore’s construction productivity. Despite the use of PPVC in many constructions, there have yet to be Post Occupancy Evaluations (POE) being conducted on flats constructed using PPVC to understand the perception of homeowners living in PPVC flats. Therefore, this study will focus on conducting a Post Occupancy Evaluation on PPVC flats in Singapore. This study aims to understand homeowners’ perception of living in a PPVC flat through the various Total Building Performance mandates. A total of 145 questionnaire responses and 2 interviews were collected and analysed. The findings reveal that while homeowners are generally satisfied with their PPVC flats, there are specific areas of concern. Homeowners’ express satisfaction with the exterior of their flats, indoor air quality, thermal performance, and visual performance of their flat. However, there are concerns regarding the quality of construction, spatial performance, and acoustics performance, particularly in the interior areas of the flats. These findings suggest a need for further attention to these aspects in future PPVC projects. The study highlights the importance of considering homeowners' experiences and perceptions in the design and construction of PPVC housing.
