Abstract

Buildings resulting from construction projects are durable assets and decisions related to construction projects have enduring impacts. In many cases, building owners prioritize only the initial costs, such as building design, construction, and equipment costs, while neglecting the future operation and maintenance costs. This research studies life cycle costing (LCC) analysis to evaluate the financial feasibility of urban housing. The LCC calculates all the costs incurred and benefits during the building's operation. The cost is generated from construction, operational, and maintenance costs. At the same time, the benefit breaks down into flat rental costs, retail rental costs, and parking costs. The costs incurred are estimated over 25 years, and the parameters of feasibility are net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR). The study generates negative NPV, BCR < 1, and 0.61% of IRR. It indicates that the project is not feasible. This research gives alternatives to make the project feasible. This study employed a trial-and-error approach to ascertain the viability of investing in flat rentals by systematically adjusting rental rates. Incremental adjustments to rental rates are tested by a series of rate hikes of 50%, 100%, 150%, and 200% using a trial-and-error approach. The project will become feasible if the flat rate increases to 150-200% of the initial rental rate.

Abstract

The development of adequate infrastructure, such as roads, bridges, and other public facilities, play a vital role in driving national economic growth. Infrastructure projects require careful planning and controlled execution to ensure effective and efficient outcomes. This study focus on addressing the common issues of delays and cost overruns that frequently occur during project implementation. The objective is to analyze the alignment between planned and actual project performance. Using a quantitative methods, this research integrated the Earned Value Method (EVM) to assess project performance. The results indicate that, between weeks 26 and 39, the project generated performance that was both ahead of schedule and below budget. This is evidenced by positive values in both schedule and cost variance (SV and CV), along with the Schedule and Cost Performance Index (SPI and CPI) values exceeding 1. However in week 40, a decrease in schedule performance was observed, leading to a slight project delay. The project’s estimated overall cost is IDR 116.8 billion, representing a decrease from the initial budget allocation, with an estimated delay is only around 18 days.
