The purpose of this paper is to explore the process, and analyse the implementation of constructability improvement and innovation result during the planning and design for seawater intake structure of fertilizer plant project.
The research methodology approach is case study method at the project level. This constructability improvement process was investigated by using constructability implementation checklists, direct observation, documented lessons learned analysis and key personnel interviews.
The case study shows that the implementation of constructability during planning and design stage for this seawater intake structure has increased the project performance as well as improved the schedule by five months (14.21 percent) and reduced the project cost by 15.35 percent.
This case study was limited to three previous seawater intake projects as references and one new method seawater intake structure at a fertilizer plant project.
A constructability improvement checklist using theory and lessons learned for the specific construction project was documented.
The findings support the relevant study of constructability and provide specific lessons learned for three previous projects and one of the new methods of the construction project and which are documented by the company.
