Perspectives of UK housebuilders on the use of offsite modern methods of construction

摘要

Despite an increasing demand for housing and wider concerns over the need to improve performance, the industry seems to be reluctant to adopt offsite technologies. Many studies have attempted to scrutinize the barriers and seek ways forward, but the perspectives of housebuilders remain unclear. UK housebuilders' views on the use of offsite modern methods of construction (offsite MMC) have been investigated. This investigation was carried out through a combination of personal interviews and a questionnaire survey of the top 100 housebuilders by unit completion. Results suggest that the traditional drivers of time, cost, quality and productivity are still driving the industry in deciding whether to use offsite technologies. Nearly two-thirds of the firms believed that there needs to be an increase in the take-up of such technologies. However, current barriers relate to a perceived higher capital cost, complex interfacing, long lead-in time and delayed planning process. Strategies recommended are centred on changing peoples' perceptions, improving procurement, providing better cost data, tackling planning and regulations, encouraging political levers and providing practical guidance. The suggestions present a model for encouraging the take-up of offsite MMC in the future.
