Three out of the three international references used in the crafting of the DPWH guidelines and implementing rules on earthquake recording instrumentation for buildings use the work written by an expert of Kinemetrics and devices of Kinemetrics. This was revealed after careful examination of the DPWH implementing rules and regulations on accelerometers required to be installed in buildings 50 meters and above under the structural code of the Philippines.  The rules were signed by DPWH Secretary Singson after being crafted by officials of the agency, the Association of Structural Engineers of the Philippines (ASEP), the ASEP committee on building instrumentation, the board of consultants (BoC) composed of Engg. Benito Pacheco, Ph.D., Engr. Ranulfo Feliciano and Engr. Antonio Avila and local building official and staff, Architect Elmor V. Vita of Paranaque City and Engr. Agustin Torres of Quezon City. 

In page 13 and 14 of the DPWH guidelines and implementing rules on earthquake recording instrumentation for buildings, 6 entries were found as references.  These are the following:

1. D.A. Skolnik et al.(2009) A quantitative basis for strong-motion instrumentation specifications. NSF CMMI Research and Innovation Conference (Hawaii)

2. M. Celebi (2002) Seismic instrumentation of buildings: Special GSA/USGS Project

3. Guidelines for ANSS seismic monitoring of engineered civil systems - Version 1.0

4. National Building code of the Philippines

5. National Structural code of the Philippines (NSCP) (2010) 6th edition

6. Industry Code and Standards

a. National Fire Protection Association

NFPA 70 National Electrical Code

NFPA 72 National Fire Alarm Code 

b.  Factory Manual Engineering and Research Corporation

 

The number 1 reference, entitled, "A quantitative basis for strong-motion instrumentation specifications" is now published in the Bulletin of the Seismological Society of America 99(6): 3275-3283 (DOI:10.1785.0120080370). Derek A. Skolnik, who is the lead author of the paper has worked with Kinemetrics since August 2009 and still works with the company as Project Manager for Development, design and implementation of structural monitoring systems. He is a civil engineer who did his postdoc at UCLA.

The number 2 reference is on seismic instrumentation of buildings, which is a special Geological Society of America/USGS Project, authored by Mehmet Celebi.  All of the instruments used in the study are Kinemetrics sensors/instruments and described in detail in Appendix A of the manuscript. A quick search using the word Kinemetrics reveals six matches describing Kinemetrics accelerometers and sensors used in the study of Celebi. 

The number 3 reference, which is the guidelines for ANSS monitoring of engineered civil system describes the history and current status of structural response  and current status of structural response monitoring with a focus on the two largest programs, the California Strong Motion Instrumentation Program (CSMIP) and the U.S. Geological Survey's National Strong Motion Program (NSMP).  In both programs, Kinemetrics plays a dominant role in terms of instruments used in the strong motion instrumentation program.  References in the ANSS guideline also include Celebi (2004), who again describes heavily Kinemetrics instruments, especially in section 3 on Special Arrays - Looking Into The Future, where Celebi describes the Millikan Building at the Caltech campus and the Factor Building at UCLA, both instrumented by Kinemetrics products. Furthermore, Kinemetrics supplied to the USGS in 2009-2010, US$ 8.69 million worth of seismic equipment to the US Geological Survey to modernize the Advanced National Seismic System (ANSS). From 2005-2012, Kinemetrics won the major seismic network projects, which include the USArray seismic network (US$15M), Global Seismographic Network (US$5M) and ANSS ($12M).

In summary, all three international references used in the creation of the DPWH implementing rules and regulations on earthquake recording instrumentation for buildings are based on work that describes Kinemetrics seismic products. It is inevitable. After all, Kinemetrics is the pioneer and innovative world leader in earthquake monitoring.
