Dimensi Arsitektur Indonesia has undertaken the maintenance and painting of Tugu
Pahlawan Surabaya. From these data it can be calculated by using the critical path
CPM (Crithical Path Method) and software programs. On the use of CPM (Crithical
Path Method) stages of completion which is preparing an action plan, arrange network,
determine the forward and backward calculation, determining the spare time of
calculation. The project which is the object of the study authors is the maintenance and

where data collected by the researchers by means of direct observation of companies
and interviews, then from the data obtained researchers performed data processing and
analysis, so as to obtain an overview of the planning time and costs that may be
considered by companies as well as can be to be completed by the company. Based on
the results of research and calculations by network planning using CPM (crithical path
method), it can be concluded that the planning time and cost network planning to use it
by using critical path method CPM appropriate to be applied in the company at the
