Evaluation of Design Process of Commercial Construction Project Based on Lean Design Concept

To determine design reliability, this study paper evaluates the design process of commercial construction projects. To streamline design efforts, decrease needless design errors, and boost design reliability, a new design workflow will be developed using commercial building concepts. The suggested procedures will give team members input on the state of the design and enable ongoing development. One of the pioneering applications of the lean methodology to building project design will be the proposed processes. Labour overruns, inadequate monitoring, and control, a lack of competence on the part of the contractor's key staff, poor planning or scheduling, and poor planning and monitoring of the refurbishment project were the top 5 variables influencing the commercial construction design process.
