Purpose: earthquake-resilient building design guidance
- The DPWH issues the advisory to guide engineering professionals, particularly Structural Engineers, undertaking designs for construction of private and public buildings and related structures.
- The advisory aims to mitigate damages due to earthquake through earthquake-resistant design practices.
Minimum design compliance standard
- The design must, as a minimum requirement, conform with the current National Building Code and its referral codes.
- Conformity must include, in particular, the National Structural Code of the Philippines, Volume I, Revised Edition 1991.
- Compliance is required for designs for construction covered by the advisory, including private and public buildings and related structures.
Reference guide for earthquake-resistant design
- The advisory directs that the Association of Structural Engineers of the Philippines (ASEP) Guide to Earthquake-Resistant Design, 1991 should be adopted as a reference.
- The ASEP guide is treated as the adopted reference guide for earthquake-resistant design.
Special advisory: liquefaction-prone areas
- Special advisory is given for areas subjected for liquefaction.
- Design Engineers are advised to address liquefaction in their earthquake-resistant design.
Special advisory: high elevations, slopes, ridge amplification
- Special advisory is given for areas on high elevations and on slopes subjected to landslides.
- Design Engineers are advised to consider the probable occurrence of “ridge amplification” in design.
- Design Engineers must incorporate consideration of ridge amplification as part of their design for such sites.
Implementation and compliance instructions
- The advisory is issued “For information and compliance”.
- Engineering professionals undertaking designs for covered construction must follow the minimum National Building Code-based standard and the adopted reference guide.
- Engineering professionals must apply the special design considerations for liquefaction areas and for high-elevation/slope sites subject to landslides and ridge amplification.
