Sumometrics Industries Inc. was established by Mr. Richard Albert Y. Lim, the company’s President and CEO, in 2011. The company is regarded as one of the pioneer-providers of earthquake recording instruments in the industry

In its first two years of operations, the company resorted to educating the industry on the usefulness of its seismic monitoring system through business presentations and product demonstrations to building owners, major property developers, building management associations, and building managers, and participation in trade shows.

Since most of the buildings in the country are compliant with the National Structural Code of the Philippines (NSCP) in accordance with the American Society for Testing and Materials (ASTM) standards, Mr. Lim decided to partner with American company Refraction Technology, also known as “Reftek”.

Refraction Technology, now a subsidiary of Trimble Navigation, has been in the seismic and structural monitoring business for the past 35 years. Reftek is one of the suppliers of the United States Advanced National Seismic Systems (ANSS), which is under the United States Geological Survey.

The American company’s extensive knowledge and experience in monitoring structures like building, dams, bridges, ground motion, volcanoes, and other structures were the factors considered by Mr. Lim to introduce Reftek’s products in the Philippine market.

Sumometrics aims to provide useful data recorded by its equipment installed on the top, in the middle, and in the basement floors of a building during an earthquake.

Useful critical information, such as Phivolcs Earthquake Intensity Scale (PEIS), Modified Mercalli Intensity (MMI) Scale, Fast Fourier Transform (FFT) Acceleration, Raw Acceleration, Velocity, etc., can be seen immediately after an earthquake.

The system seems like installing a ‘black box’ inside the building to record all movements and behaviors of the structure during an earthquake. In-depth analyses of the data recorded, such as the Maximum Acceleration, Spectral Intensity, Predominant Period, Mean Period, 2PI*Vmax/ Amax, Maximum Velocity, Maximum Displacement, Cum Abs Velocity, Arias Intensity, Arias Duration (5-75), Arias Duration (5-95), JMA intensity, MMI scale, and PEIS are broken down to three axis movement: vertical, longitudinal, and traverse.

All these information can be seen as raw files waveform or numerical files. These are the important critical results that can be utilized by structural engineers using structural engineering software.

To date, Sumometrics has already installed seismic accelerograph system in almost all types of building structures, from single to multiple buildings sharing a common podium or basement, casinos, banks, residential buildings, and mixed use towers around Metro Manila.

Clients can attest to Sumometrics’ superior standards of installation using only branded intermediate metal conduit (IMC) or conduit pipes approved by clients. Sumometrics is the first company to introduce NEMA enclosures on all its accelerographs to prevent accidental triggering and tampering by anyone.

All wires used are also branded using only the best brands available in the market. The company was even the first to introduce a monitoring station in administration office, or the CCTV room, wherein the client can view the performance of the three accelerographs located at different levels of the building. From this central monitoring station, one can extract and print data from the three accelerographs.

Sumometrics is, likewise, the first company to introduce device tagging. It tags its conduit pipes, NEMA enclosures, pull boxes, and accelerograph boxes as its standards of superior installation, and so their seismic lines and equipment cannot be mistaken by other maintenance crew from other utility providers. The company strictly implements “no exposed wires” regulations to avoid cutting or tampering of the system.

All installations come with an as-built plan duly certified and signed by a professional electrical engineer (PEE). The plan contains the location and orientation of the accelerograph with column reference of which was duly certified by a structural engineer.

Another advantage of using Sumometrics seismic system is due to the internal battery of the accelerograph, which is rated to operate for 36 to 48 hours even without power from the AC source. Upon resumption of the electricity, the battery will then recharge to be ready again for future use.

Now on its expansion phase, the company is looking at remotely monitoring accelerographs, using its own software or the Trimble 4D software, which will entail additional costs. In the future, this will link all buildings where it has installed accelerographs, and they can be monitored in one central monitoring station.

The REFTEK 130-SMHR Seismic Accelerograph exceeds the minimum specification requirements of the 2015 Department of Public Works and Highways (DPWH) regulations on earthquake recording instruments as shown by the certification provided by the company’s supplier Trimble Navigation.

Moreover, Sumometrics’ system specifications is in accordance to the ASTM standards, which results are in units of measurement accepted worldwide, especially the USGS, Philvolcs, and other major global seismic institutes.
