Government building projects in the National Capital Region (NCR) face persistent quality challenges that affect safety, functionality, and public trust. This study investigates the factors influencing construction-phase quality, focusing on leadership, people, policy and strategy, partnership and resources, and process. A descriptive research design was employed, using a structured survey administered to 45 technical personnel from general contractors managing Department of Public Works and Highways (DPWH) projects. Stratified random sampling ensured representation across roles and experience levels. Data were analyzed using frequency distribution, weighted mean, standard deviation, ranking, and one-way ANOVA to assess perceptions and identify significant differences. Process-related factors received the highest evaluation, particularly coordination among project teams (WM = 4.57), site inspection (WM = 4.55), and quality control (WM = 4.53). People-related factors such as teamwork and training also ranked highly, underscoring workforce competence as vital to quality outcomes. Leadership commitment and proactive change management were influential, while resource constraints and policy gaps contributed to deficiencies. ANOVA results indicated no significant differences in perceptions across age, designation, or experience, suggesting shared recognition of these factors across demographics. Findings highlight the critical role of process integration, workforce development, and leadership support in ensuring construction quality. Addressing resource limitations and policy inconsistencies can further strengthen outcomes. Improving government building project quality requires coordinated processes, skilled personnel, and strong leadership. The study proposes an implementation plan emphasizing inspection, training, and stakeholder collaboration to enhance public service delivery.
