Abstract

Residential drainage systems play a crucial role in controlling rainwater runoff to prevent localized flooding and puddles. The development of residential areas along Jalan Gunung Guntur, Harjamukti District, Cirebon City, has led to significant changes in land use, resulting in increased surface runoff. Based on field observations, this area frequently experiences puddles during medium- to high-intensity rainfall. This phenomenon is suspected to be caused by inadequate drainage channel capacity, sedimentation, and lack of routine maintenance. This study aims to determine rainfall intensity and design flood discharge based on the time of concentration, evaluate the capacity of existing drainage channels, and identify the causes of puddle formation. The research method employed is a quantitative descriptive approach with hydrological and hydraulic analyses. The hydrological analysis includes calculating design rainfall, rainfall intensity, time of concentration, and flood discharge using the rational method. Hydraulic analysis is conducted to determine the channel cross-sectional capacity using the Manning formula. The evaluation results indicate that several existing drainage channels are unable to accommodate the runoff discharge occurring within a specific return period, potentially causing puddle formation. Therefore, redesigning or normalizing the channel dimensions is necessary to increase capacity, ensuring the optimal functioning of the drainage system and minimizing the risk of flooding.

Abstract

The implementation of construction work, there are still many problems, namely schedule mismatches, delays, and cost calculations that are sometimes inaccurate because they still use conventional methods. In the Al-Multazam Islamic Boarding School Building Construction project, Kuningan still uses traditional methods, where this method has the potential for human error because in making calculations it can be wrong to enter data which will ultimately change the calculation results to be greater. This research aims to show that the BIM method is very important to be applied in construction projects to streamline work productivity in building construction projects. In this case, there are differences in the results of the calculation of Quantity Take Off on the project, the difference in the results of the analysis shows that there is a difference between the existing volume and the volume of the Quantity Take Off results using the BIM concept, Foot plate foundation work has an average difference of 6.67%, Tie Beam has a difference of 7.62%, Beams have a difference of 5.30%, Columns have a difference of 8.26%, and Floor Plates have an average difference of 2.51%.  This research has implications for the application of BIM to enable a more structured, efficient, and accurate planning and implementation process, thereby reducing the potential for errors caused by human factors. In addition, the use of BIM can also increase efficiency in overall project management, including in schedule monitoring, cost estimation, and resource management, which in turn can increase work productivity on building construction projects.
