The processes for management of historical data in construction have many problems according to construction firm$^{circ}{phi}$s participating in some of the processes. This study analyzed about current process and provided improved processes with IDEF method and simulation. The proposed $lceil$To-Be$ floor$ model is more effective than $lceil$As-Is$ floor$ model according to the result of simulation performance. It is revealed that the productivity in the construction company is more improved than that of the owner from the results of the system simulation.
