Abstract

This study compares maintenance scenarios for the Integrated Lecture Building at Manado State Polytechnic through FEMA P-154 Rapid Visual Screening (RVS) and life cycle cost analysis. Six nonstructural and building-services packages are compared under reactive maintenance (S0), scheduled preventive maintenance (S1), and minor nonstructural retrofit with preventive maintenance (S2). The recorded RVS score of 2.0 lies at the screening cut-off; documented defects warrant structural engineering evaluation. Costs are expressed in modelled constant-2026 rupiah over 2027–2046. A researcher-selected nominal benchmark of 6%, obtained by upward rounding of the supplied BI-rate mean, is converted through Fisher using assumed inflation of 2.5%, giving a real rate of 3.414634%. Revised present-value costs are IDR 112.896, 112.863, and 113.503 billion for S0, S1, and S2. S1 saves only IDR 33.00 million (0.029%) relative to S0. Demolition at year 20, a 10% demolition allowance and 5% inventory salvage are explicit hypothetical disposal assumptions. S1 has a marginal conditional advantage, dependent on assumed price dates, cost allocations, equivalent service requirements and structural verification.
