Malaysia is experiencing an encouraging socio-economic development, especially in its
quest towards Vision 2020 and achieving the status as a developed country. The success can be
attributed to the government’s efforts and commitment in developing projects, which include the
construction of new townships and public infrastructures. Through the implementation of
Environmental Management Plan (EMP) during the construction phase, the government has taken
great efforts and initiatives to ensure that construction projects are well-developed in a sustainable
manner. Unfortunately, these rapid physical developments affect and pollute the surrounding
environment, even though EMP is implemented at the construction site. The effectiveness of
sustainable construction methods in the plan has been found to be very limited in the actual industrial
practice. Hence, this paper aims to determine the important criteria needed to be incorporated into
EMP in enhancing and ensuring its effectiveness in managing environmental aspects during the
construction stage.
Acquisition of adequate and meaningful research data, as well as the appropriate analysis
is important in ensuring the strategic direction and objectives of the study are well achieved. Data
analysis is an important element in any study. Good data analysis is obtained from the study that is
carefully planned based on an appropriate design, as well as the approach that is used in the process
of analysing the data. The objective of the study to be conducted is to determine the weight of criteria
for sustainable construction. Therefore, the right selection of data analysis is very important to ensure
that the objectives are successfully achieved. This manuscript writing presents the description of the
data analysis used in this study, by applying the Rasch measurement model to meet the objective. In
addition, by using this measurement model, the importance of calibrating the measurement instruments
are also highlighted, which involves separating the misfit raw data through the analysis to ensure
statistically more accurate analytical results. Evaluation of the quality of the technical aspects for each
of the involved item is very important in the measurement model. The analysis will be able to improve the reliability of the items which could indirectly serve the purpose of calibrating the instrument to
ensure a more accurate measurement to produce a meaningful research.
Selection of a suitable and appropriate method is an important aspect in ensuring successful
implementation of a research. The proposed study aims to obtain weights for sustainable construction
criteria from the input and perception of industrial practitioner, and also to explore their opinion on
the criteria. Therefore, the selection and use of study implementation method will determine the
direction of the study whether the intended objectives can be achieved. This manuscript writing presents
the description of the structured interview used to obtain and collect the required data. The suitability
and implementation of the methods have been described in this study, in which the ultimate aim of its
application is to ensure that the collected data is meaningful to the study.
