Design process improvement by integrating principles of constructability knowledge to the monorail system project

摘要

The use of constructability analysis is the process of determining that the designers utilize common construction practices that are readily available in the contracting industry to complete a project. The use of constructability analysis provides an opportunity for input from the contracting industry to the design professional to ensure that efficient, economical and quality solutions are reached. The timely execution of a construction project is very important to the client, who makes plans and commitments on the basis of the project’s anticipated completion date. Failure of design professionals to consider how a builder will implement the design can result in scheduling problems, contract changes, increase of cost, delay, variations even dispute during the construction process. Many design firms have indulged in constructability program that is launched as early as conceptual planning stage of the project. Hence, the aim of this study is to enhance monorail design process through integration of constructability concept. The objective could be determined by investigating whether any research and study has ever been approached on the implementation of constructability review analysis on any monorail projects in Malaysia. Subsequently to identify whether there is an element of Constructability Review Analysis being implemented to the monorail project in Malaysia. Furtherance to this, a Constructability Review Checklist is to be created specifically for the monorail projects, ensuring its integration into design process. There are three (3) phases of this investigation. Phase one (1) starts with the determining the objective and scope and subsequently research through literature reviews and preliminary interviews. Phase two (2) consist of studying the case study by investigation from the existing and on-going KL monorail project and constructability issues. Phase three (3) comprises of developing and validating on improving the design process and fine tuning the design constructability checklist by interviewing an expert on monorail consultants. Finally, the conclusion was there has been no study and research being approached into the constructability review analysis on any monorail projects in Malaysia. However, it was identified there are elements of constructability review analysis being implemented in the KL Monorail Project. Hence, a constructability review checklist was developed ensuring its integration into the constructability review design process
