Abstract:
This research aims to (1) identify factors contributing to delays in road construction projects of Nonthaburi Provincial Administrative Organization and (2) develop preventive strategies for preventing delays in road construction projects. The study was motivated by findings that 66.67% of road construction projects experienced delays during the fiscal years 2022-2024, significantly impacting project management and road users. The research employed a quantitative methodology, collecting data through questionnaires from 40 purposively selected participants, comprising 20 employer representatives (government officials) and 20 contractor representatives (private sector). The 5-point Likert scale questionnaire, demonstrating content validity of 0.74 and reliability with Cronbachs alpha coefficient of 0.982 was used. Data analysis was conducted using descriptive statistics. Results revealed that all six factor exhibited moderate impact levels. Other construction factors demonstrated the highest mean impact (3.08), followed by personnel factors (2.90), machinery factors (2.86), construction method factors (2.84), financial factors (2.77), and materials and equipment factors (2.63). The most critical sub-factors included inappropriate work time planning (3.48), low-skilled workforce (3.47), design modifications during construction (3.40), and obstructions from existing structures and utility infrastructure (3.40). The study proposed comprehensive preventive strategies encompassing workforce skill development, disbursement system improvements, efficient project planning, and enhanced community participation. The research findings provide practical insights for enhancing road construction project management efficiency in road construction.
