Introduction

In the world of construction, effective project management is crucial for the success of a project. One of the key factors that contribute to the success of a project is the accurate calculation of the budget plan. This is where cost estimation becomes a vital aspect of the project management process. The accuracy of the estimated cost at the initial stage of the project has a significant impact on the profit or loss of the project. Therefore, it is essential to use a reliable method for estimating construction costs.

The Importance of Cost Estimation in Construction Projects

Cost estimation is a critical component of the construction project management process. It involves predicting the costs associated with the project, including labor, materials, equipment, and other expenses. The accuracy of the estimated cost has a direct impact on the project's profitability. If the estimated cost is too low, it may lead to budget shortages, which can cause delays and cost overruns. On the other hand, if the estimated cost is too high, it may result in unnecessary expenses and reduced profit margins.

The Unit Price Analysis Method

One of the commonly used methods for estimating construction costs is the unit price analysis method. This method involves analyzing the cost of individual components of the project, such as materials, labor, and equipment, and then multiplying these costs by the quantity of each component required for the project. The unit price analysis method is widely used in the construction industry due to its simplicity and ease of use.

The PUPR Permen Method

In addition to the unit price analysis method, the PUPR Permen method is also used for estimating construction costs. The PUPR Permen method involves accumulating the costs of materials, labor, and equipment used during the project implementation. The data used in this analysis comes from a daily project report that reflects the actual field conditions. This method provides a more accurate estimate of the costs associated with the project, as it takes into account the actual costs incurred during the project implementation.

The Use of Microsoft Project Software

Microsoft Project software is a powerful tool used for project management and cost estimation. It provides a range of features and tools that enable project managers to create detailed project schedules, track progress, and estimate costs. The software also allows project managers to analyze the costs associated with the project and identify areas where costs can be reduced.

Case Study: The Wahid Residences Apartment Development Project

The Wahid Residences apartment development project is a case study used to demonstrate the effectiveness of the PUPR Permen method combined with Microsoft Project software in estimating construction costs. The project involved the construction of a high-rise apartment building in Medan, Indonesia. The project required the use of reinforced concrete work on the foundation, which was estimated to cost Rp. 6,305,682.44 using the contractor's analysis method. However, the PUPR Permen method processed through Microsoft Project software resulted in an estimated cost of Rp. 7,774,454.00, which is a significant difference of Rp. 1,468,771.56.

Cost Analysis Results

The results of the analysis of reinforced concrete work costs on the foundation, according to the calculation of the contractor, showed the figure of Rp. 6,305,682.44. Meanwhile, cost analysis using the PUPR Permen method processed through the Microsoft Project resulted in an estimated cost of Rp. 7,774,454.00. The difference between the two methods is quite significant, which is Rp. 1,468,771.56, where the estimated contractor costs are lower than the estimates produced by PUPR Permen.

Explanation of Methodology

Cost analysis using the PUPR Permen method involves the accumulation of material costs, workers' salaries, and the costs of the tools used during the project implementation. The data used in this analysis comes from a daily project report that reflects the actual field conditions. In this case, observation of the needs and use of tools and the amount of labor used is very important to get a more accurate estimation rate.

Conclusion

In conclusion, the use of the PUPR Permen method combined with Microsoft Project software provides a more realistic picture of the estimated cost of reinforced concrete work on the foundation. Although the contractor analysis shows a lower cost, this needs to be observed so that there is no budget shortage in the implementation stage. Therefore, it is essential for project managers to consider the results of analysis from various methods so that the budget compiled can be more targeted and in accordance with conditions in the field.

Recommendations

Based on the results of this study, the following recommendations are made:

Use of PUPR Permen Method: The PUPR Permen method should be used in conjunction with Microsoft Project software to estimate construction costs.

Conclusion

In conclusion, the use of the PUPR Permen method combined with Microsoft Project software provides a more realistic picture of the estimated cost of reinforced concrete work on the foundation. The results of this study demonstrate the effectiveness of this method in estimating construction costs. Therefore, it is essential for project managers to consider the results of analysis from various methods so that the budget compiled can be more targeted and in accordance with conditions in the field.
