Abstract
Workspace is the key to manage other resources on the construction site. It should be carefully planned to facilitate construction execution. Lack of workspace planning creates space conflict which provides a negative impact on productivity, quality, constructability, safety and duration to complete a project. Conventional construction planning methods are not able to provide sufficient explanation regarding space execution needs at sites. In fact, existing workspace planning techniques does not provide a planning approach and comprehensive solutions for workspace conflict. Furthermore, many other factors of lack of workspace planning leads to workspace issues have been identified but have not been tested in industrialised building system (IBS). In depth research will be able to identify comprehensive factors and this will assist in work space planning to be more specific, detail and reduce the negative impact on construction performance. This study is undertaken to identify the main factors of lack of workspace planning which creates workspace conflict at construction sites, and to research and review the relationship between these factors and workspace conflict. The study also identifies the workspace planning techniques practiced by contractors of IBS projects and types of interferences and workspace conflict in the actual IBS construction environment. Quantitative approaches adopting self-administered questionnaire method included 168 samples and structured interview with eight IBS project contractors and clients was utilized. Relative Importance Index (RII) and Structural Equation Modelling analysis techniques (SEM) were used in the data analysis and descriptive analysis was used for data gathered through the interviews. The results showed that there are 10 main factors for each category of variables which is Management related issues, Jobsite Planning, Resource and Logistics. For the issues under variables Projects Characteristic and the External Environment, eight main factors were identified. The relationship analysis finding shows only two variables pose significant positive impact to workspace conflict which is Management issues and Projects Characteristic and the External Environment.
Conventional techniques underlying macro, micro, and the path space planning techniques employed by contractors in which preparation of an informal and unspecified manual is practiced. Experience, and site layout plan was identified as fundamental aspects of planning. This research also reveals 44 factors led to disturbance and workspace conflict in IBS projects and confirms that 83.33% from the identified factors was from Management, Jobsite Planning (60%), Resource and Logistics (45%), and Projects Characteristic and External Environment factors (87.50%) was identified as the main factors that creates 17 types of interferences and workspace conflicts. To sum up, a work space planning model was proposed to reduce space issues and could benefit the contractors in the workspace execution planning in IBS projects.
