Analyzing the critical delay factors for construction projects in the public sector using relative importance index and machine learning techniques

This study aims to identify the causes of delays in public construction projects in Thailand, a developing country. Increasing construction durations lead to higher costs, making it essential to pinpoint the causes of these delays. The research analyzed 30 public construction projects that encountered delays. Delay causes were categorized into four groups: contractor-related, client-related, supervisor-related, and external factors. A questionnaire was used to survey these causes, and the Relative Importance Index (RII) method was employed to prioritize them. The findings revealed that the primary cause of delays was contractor-related financial issues, such as cash flow problems, with an RII of 0.777 and a weighted value of 84.44%. The second most significant cause was labor issues, such as a shortage of workers during the harvest season or festivals, with an RII of 0.773. Additionally, various algorithms were used to compare the Relative Importance Index (RII) and four machine learning methods: Decision Tree (DT), Deep Learning, Neural Network, and Naïve Bayes. The Deep Learning model proved to be the most effective baseline model, achieving a 90.79% accuracy rate in identifying contractor-related financial issues as a cause of construction delays. This was followed by the Neural Network model, which had an accuracy rate of 90.26%. The Decision Tree model had an accuracy rate of 85.26%. The RII values ranged from 68.68% for the Naïve Bayes model to 77.70% for the highest RII model. The research results indicate that contractor financial liquidity and costs significantly impact construction operations, which public agencies must consider. Additionally, the availability of contractor labor is crucial for the continuity of projects. The accuracy and reliability of the data obtained using advanced data mining techniques demonstrate the effectiveness of these results. This can be efficiently utilized by stakeholders involved in construction projects in Thailand to enhance construction project management.

Analisis Faktor Keterlambatan Pekerjaan Konstruksi Drainase dengan Menggunakan Metode Kaiser Mayer Oklin (KMO)

This research aims to identify factors that cause delays in implementing the Urban Drainage project in Kepatihan Village, Bojonegoro Regency, using Regional Revenue and Expenditure Budget (APBD) funds. The research method used a population involved in drainage construction, using a saturated sampling technique with 39 respondents. Data collection used questionnaires for primary data and secondary data obtained from project schedules, cost budget plans and workforce data. Data analysis uses factor analysis, descriptive analysis, and cross tabulation analysis. Factor analysis uses the Kaiser Mayer Olkin Measure of Sampling Adequacy (KMO-MSA) method. The KMO test was carried out with a significance value from the Bartlett Sphericity Test of less than 0.05 to determine the suitability of the variables. The KMO-MSA process is carried out by calculating the Kaiser Mayer Olkin (KMO) value. The KMO value ranges between 0 and 1, where a higher value indicates a better match. Apart from that, Bartlett's Test of Sphericity was also carried out to test the significance of the relationship between variables. If the test results are significant (p < 0.05), then these variables are suitable for proceeding to further factor analysis. The results of the cross-tabulation analysis show that the labor variable (X2) is the main factor influencing delays in drainage construction projects, with a significance value (sig) < 0.05. Based on the results of the descriptive analysis, the labor factor indicator (X2) which is the factor that has the most significant influence on construction project delays, is the variable X2.1 in the form of labor availability with a mean of 5.67 and a percentage value of 5.12%. This suggests that a lack of labor can cause delays in project implementation, potentially affecting overall project progress and quality.
