Managing multiple construction projects has become a defining challenge in the Philippine construction industry, particularly in Laguna, where contractors face overlapping schedules, shared resources, and diverse stakeholder demands. This study investigates the common problems encountered and the management strategies employed to address them. A mixed-methods design was adopted, combining quantitative surveys and qualitative recommendations from 50 contractors, project managers, and engineers. The instrument measured challenges in resource allocation, prioritization, communication, and scope management, while open-ended responses provided insights into recommended solutions. Weighted mean analysis and thematic coding were used to interpret the data. Findings revealed that contractors frequently encounter issues in specialized skill shortages, equipment delays, miscommunication, and scope changes. Resource allocation and communication barriers were the most pressing concerns, with language and cultural differences exacerbating collaboration difficulties. Scope creep was also identified as a recurring problem. To mitigate these challenges, contractors applied strategies such as centralized project management offices, comprehensive resource assessments, prioritization frameworks, and project management software. Continuous communication and clear objectives were also emphasized as critical to success. The study highlights the importance of structured planning, adaptive leadership, and technological integration in multi-project management. Strategies, such as Lean-Agile approaches, BIM integration, and sustainability-driven practices, were identified as promising solutions to enhance efficiency and reduce risks. Effective management of multiple construction projects requires proactive resource planning, disciplined scope control, and collaborative communication systems. The proposed action plan underscores the need for continuous improvement and digital transformation to strengthen industry practices.
