Variation orders impacted the project performance, procurement delay, quality degradation, disputes among professionals, decline in firm reputations, increase in overhead expenses etc. in projects of Nepal Police. But there have been few researches carried out about cause and impact of variation order in road, school building and hydropower projects of Nepal. However, no research work has been carried out about variations orders in the building projects under Bagamati Province Police Office, Hetauda. So, this research aims to highlight "Assessment of Variation Order on Selected Building Construction Projects Implemented by Nepal Police at Bagamati Province of Nepal" as well as to suggest preventive measures to reduce the variation orders in similar building construction projects. For this purpose, 9 building construction projects were considered. Questionnaires for Causes, and Impacts of Variation Order in Selected Building Projects Implemented by Nepal Police at Bagamati Province of Nepal were provided to potential respondents 60 i.e., client and contractor through KOBOTOOL Box forms and emails. Among 60 questionnaires, 95% i.e., 57questionnaires respond were received. Data were analyzed using MS Excel and RII. KII conducted to identify preventive measures to reduce variation order in building construction projects in future. For Assessment of Variation Order on Selected Building Construction Projects Implemented by Nepal Police at Bagamati Province of Nepal, RII was used. The major client related causes of variation orders are changes in design during the construction period (RII=0.628), lack of timely disbursement of budget (financial resources) (RII=0.625) and poor quantity estimation of the project (RII=0.618). The major contractor related causes are lack of timely disbursement of budget (financial resources) (RII=0.704), poor quantity estimation of the project (RII=0.643) and changes in design during the construction period (RII=0.626). Result have shown that impacts of variation order were delay in payment (RII=0.757), time over run viii (RII=0.704) and increase in project cost (RII=0.670). Carry out detail site investigations and sub- surface investigation during the planning phase (RII=0.895), preparation realistic bill of quantities (BOQ) and procurement documents on the planning phase (RII=0.891) and in depth review of designs drawings and plans before tendering stage (RII=0.874) were identified preventive measures to reduce the variation orders in similar building construction projects in future obtained from KII. Thus, variation order is common in construction projects of Bagamati Province Police Office Hetauda, Makawanpur.
