The Philippines is located on the Pacific Ring of Fire. This is a concern for construction professionals in Metro Manila. A big earthquake, called “The Big One” can happen anytime. Construction project managers and structural engineers in Metro Manila and nearby areas like Cavite, Laguna and Bulacan must use earthquake-proof construction methods.
- Traditional construction methods are not enough to protect buildings from earthquakes.
- The National Structural Code of the Philippines (NSCP) 2015 sets standards for earthquake-proof construction.
NSCP 2015 Standards
The NSCP is like a guidebook for Filipino engineers. The 2015 update emphasizes the importance of buildings being able to bend and sway without collapsing during an earthquake.
- Standard steel bars (rebars) are not strong enough to protect buildings from earthquakes.
- Seismic-grade steel is stronger and more flexible making it essential for earthquake- construction.
Understanding Seismic Grade Steel
Seismic-grade steel is like gum. It can stretch and deform without breaking. This property, called ductility makes it perfect for earthquake-proof construction.
- Seismic-grade steel can withstand the shaking of an earthquake and maintain its integrity.
- Using rebars in critical areas is a huge risk in seismic risk management.
The Financial and Reputational Costs of Ignoring Seismic Risk Management
Ignoring risk management can have severe financial and reputational costs.
- The collapse of a high-rise structure results in loss of life and endless legal battles.
- Non-compliance during inspection can halt a project indefinitely resulting in penalty fees and extended timelines.
Focusing on Highly-Seismic Areas
Metro Manila and nearby areas like Rizal, Laguna and Bulacan are highly prone to earthquakes.
- Developers must prioritize high-tensile steel in areas like Quezon City, Cavite and Bulacan.
- Vertical load-bearing elements, beam-column joints and foundations must be designed to withstand earthquakes.
Simple Steps for Compliance
To ensure compliance with NSCP 2015 standards project managers must:
- Demand Mill Test Certificates (MTCs) for steel.
- Specify PNS and ASTM Grades for high-tensile steel.
- Educate team members on the difference between seismic-grade rebar.
Key Takeaways
- The seismic threat from “The Big One” is real. Demands more than standard construction materials.
- Compliance with NSCP 2015 standards requires the use of tensile highly-ductile seismic-grade steel.
- The higher initial cost of seismic-grade steel is an investment that reduces long-term safety liabilities.
