In order to achieve the objectives, Figure 1.1 illustrated the schematic of research methodology for this study. Generally, it consists of four distinct phases, which are phase 1, phase 2, phase 3 and phase 4.
3.1 Phase 1
Selection of the topic has been done after gone through JKR listing of significance topics that can contribute to department as a whole. Topic of the study and proposed productivity rate of roof works is important to JKR building project scheduling to ensure all project can be completed on time with good quality. Based on previous researchers, there are several measurements on productivity rate in construction. This study will be focusing on the identification of factors that influencing roofing works productivity in JKR projects. From this scenario, the objectives of this study has been identified which are identifying of factors influence, the relationship and the establishing productivity rate of roof works. In such way, the focus of this topic must be in line with study limitation.
In order to strengthen knowledge and ideas in this research area, extensive reading from journals and books must be thoroughly done. Besides that, preliminary site observation has been conducted to the selected site. Furthermore, the preliminary interview was conducted to get overview information about productivity rate of roof works. Due to time constraint, the observation has been done only for school projects.
3.2 Phase 2
A few samples of studies will be identifying purposely for running through the method of productivity measurement for getting accurate and practical data. Observation on quantity of roof works per man hours should be performing at site. During observation at site, interview with the expert is use as a tool to collect information data on how the productivity rate of roof works can be estimate and what are the factors influences the productivity rate
Several interviewees will be selected based on qualification and experienced more than 10 years especially contractors and suppliers. Beside that, questionnaire will be distributed to technical person such as supervisor, engineer, manager and contractors to obtain their opinion in term of productivity rate of roof works.
3.3 Phase 3
In this stage, all the data from the questionnaires and interviews will compile. The data will be analyze accordingly and transform into productivity rate. Data analyzing, there will be a confirmation on what are the factors influence productivity rate of roof works will be getting through data analyzing, while standard productivity rate metrics of roof works will be producing after transform all the data into productivity rate by using appropriate statistical analysis.
3.4 Phase 4
Extract from data obtained in Phase 3, some proposal or recommendation will be highlighted in order to enhance a metrics of standard productivity rate for future building project scheduling.
The expected results of this study in next semester are:
a) List of factors that influence the productivity rate for roof works,
b) The critical factors affecting most to productivity rate for roofing works,
c) A metrics of productivity rate for roof works as a standard and guideline for improving JKR projects scheduling.
