劳动生产率和用地面积是衡量一个预制厂生产水平的重要标志。国外预制厂劳动生产率一般为250立米左右(见表1)。北欧、北美一些新建的工厂,劳动生产率更高,每人每年可达 1000立米以上,但这只是少数。国外一些预制厂,在每平米工厂用地面积上,可年产构件0.6～1.5立米(见表2)。个别的厂(如丹麦的拉逊—纳尔逊预制厂)平均每平米用地生产构件达11.6立米。 Labor productivity and land area is an important indicator of a prefabricated factory’s production level. The labor productivity of foreign prefabricated factories is generally around 250m (see Table 1). Some newly built factories in Northern Europe and North America have higher labor productivity and can reach more than 1,000 liters per person per year, but this is only a few. Some foreign prefabrication factories can produce 0.6-1.5 m3 of components per square meter of factory land (see Table 2). Individual plants (such as the Laxon-Nelson prefabrication plant in Denmark) produce an average of 11.6 m3 per square meter of land.
