Productivity Measuring Tool
Realising the importance of measuring and benchmarking , in the hope of improving the productivity of the industry , CIDB , together with the Construction Research Institute of Malaysia ( CREAM ), have developed a tool known as the Productivity Measuring Tool ( PMT ) which aims to measure productivity of building construction projects in the country . The PMT focuses on labour productivity improvements as it will have a bigger overall effect on labour-intensive sectors such as construction .
The PMT defines productivity performance of building construction projects as the ratio of total constructed gross floor area ( GFA ) to total man-days . The constructed GFA in this context represents the total area of covered floor space measured between the centre line of party walls , including the thickness of external wall but excluding any voids . Meanwhile , a man-day is defined on the basis of one man working for eight hours per day . The PMT consists of a productivity performance equation to calculate and measure productivity performance of construction projects , and a productivity grading system to grade and rank them according to the productivity performance shown in Figure 5 .
Note that the PMT categorises productivity performance of above 10 sq . ft ./ man-day as the highest productivity performance of building construction projects i . e ., Grade A productivity performance . According to Blueprints for Successful Public Housing projects , published by Singapore Concrete Institute Housing , it was revealed that the overall site labour productivity for public housing stood at 1.0 m 2 per man-day which is equivalent to 10 sq . ft / man-day ( Ming & Suan , 2006 ). As there is no reliable or evident value yet for overall productivity in Malaysia , CIDB Malaysia took this figure as an appropriate indicator to be used as benchmark in developing the PMT .
Malaysia ’ s First Digital IBS Facility
With the aim of adopting digital transformations , Construction 4.0 is expected to play a critical role in transforming the construction industry . The advent of IR4.0 has culminated in the introduction of automation in production activities , especially component production . It offers more autonomous , flexible , and co-operative working environment as well as providing a greater range of capabilities and flexibility in production , thus helping to boost the productivity of construction projects .
