In the year 2019, COVID-19 entered the whole world and challenged every aspect of society, especially construction firms. Pandemic protocols and suspension of work were unavoidable as the government ordered it to prevent the spread of the virus. However, knowing construction projects, following their schedule, and having enough resources were crucial to finish their ongoing projects on time. In this research, a mixture of quantitative and qualitative types of study was used to collect the necessary data by conducting survey questionnaires and a Likert scale to 145 respondent companies in the City of San Fernando, Pampanga. And during the pandemic, it was found that more than half of the respondent companies were handling private projects. Most of them experienced a negative slippage because of the lack of materials, lack of manpower, and lockdown restrictions. The overall effect of the pandemic in terms of resources was moderate but it greatly affected the construction firms financially because of the sudden inflation of construction materials. As well as the effect of lockdown restrictions, health protocols, and requirements brought a huge impact on the deliveries and supply of materials causing the project managers to have difficulties in finishing their projects on time. That is why giving attention to following the schedule is substantial.
