Abstract: The growth of the manufacturing industry is quite high, The manufacturing industry is growing rapidly demanding more availability of factory buildings. The trend of using steel structures at this time is reasonable considering that WF steel can be a reliable support for the structure. The annual steel construction growth is predicted to reach reaches 5.5%, until 2025. Unfortunately, the number of lateness of steel construction projects reached 20-30% and it’s waste reached 9.6%. Based on the delay problems mentioned above, the researchers implemented M-PERT to reduce the amount of delay and at the same time providing accurate scheduling that has an accuracy of up to 99%, while applying Lean Construction application could reduce waste down to 8%. The results of statistical analysis using SPSS obtained twelve influential factors, namely: building planning, scheduling, preparation, delivery methods, location optimization, work methods, activity duration distribution, network time determination, managing uncertainty supply, merging project activities, network similarities, timely scheduling. As a general illustration, the Lean Construction application could reduce the waste down to 7.78%. As for scheduling in steel construction, the application of M-PERT produced an accuracy of 98.89% or an error of 1.1%, interesting amount to be further study.
