The Makati City government has ordered owners of high-rise buildings in the city to install seismograms (a.k.a. accelerometers) to monitor ground movement during earthquakes as well as the building's response during typhoons. Makati mayor Jejomar Binay cited the recently issued memorandum by Secretary Rogelio Singson of the Department of Public Works and Highways (DPWH)* to building officials and local engineers as the reason for this necessity. The directive also covers buildings under construction as well as those still in the design stage. City building official and city engineer Nelson Morales issued a memorandum to all developers, contractors, owners, and administrators of high-rise buildings to comply with the said directive. Buildings completed without the device installed will not be granted occupancy permits by the city government, he said.
*DPWH Memorandum Circular no. 03 (March 31, 2011) Section 105(2) of the National Structure Code of the Philippines, requires the installation of accelerometers or seismograms in structures measuring over 50 meters high.
Ummm... I think they meant seismographs. Seismograms are the paper records that seismographs spit out. You don't install paper records! Sheesh, might as well build the high-rises with toilet paper.
Seis-mo-what?
