CONCRETE Stone Corp. (CSC) presented its concrete modular construction system to President Ferdinand R. Marcos, Jr. and key government officials, highlighting how factory-built classrooms can be rapidly deployed to help address classroom shortages across the country.
During the visit, officials from CSC guided the President and Education Secretary Sonny Angara through the company’s modular classroom facilities in Bataan. The system features classroom components that are manufactured in a controlled factory environment and later assembled at CSC’s Bataan plant, ensuring consistent quality and faster completion timelines.
The modular classrooms comply with Department of Education (DepEd) standards and have a floor area of 75.6 square meters, accommodating up to 42 learners and one teacher per classroom. Designed to support immediate educational needs, the classrooms demonstrate how modern construction methods can help accelerate the delivery of learning spaces.
Built using factory-produced components—including walls, slabs, beams, stairs, and retaining walls—the concrete modular system enables quicker installation, improved quality control, and reduced on-site labor requirements. The structures are engineered to withstand harsh weather conditions and are resilient enough to endure earthquakes of up to magnitude 8, providing safe, durable, and eco-friendly classrooms adaptable to various educational settings.
President Marcos also visited Mariveles National High School – Cabcaben Annex (Alasasin) in Bataan, where he inspected classrooms currently being used by teachers and students. The school has been utilizing prefabricated classrooms to support its growing student population.
According to Jerry C. Perello, principal of Mariveles National High School – Cabcaben Annex (Alasasin), the prefabricated modular system allowed classrooms to be constructed in a significantly shorter period of time. This enabled the school to make the facilities available to students sooner and immediately address classroom shortages.
CSC president Engr. Alfredo Comendador, Jr. emphasized that concrete modular construction has already been widely adopted in neighboring countries such as Hong Kong and Singapore. He noted that the system helps speed up construction, improve build quality, and provide safer learning environments for students, while also supporting broader infrastructure development through faster and more resilient buildings.
