Fault Mapping and Trenching for properties of Ayala Land in Marikina and Laguna: 

As part of their Technical Due Diligence (TDD) process in land development, GEOS was contracted to conduct fault mapping studies to determine general location of faults in several properties. To verify the location of the fault traces, trenching activities were done in key sections of the fault trace. The verified and validated fault trace information can then be used for property and site planning to ensure the safety of the residents and the community.

Vulnerability Assessment of Compostela Valley and Davao Oriental contracted by USAID thru The Louie Berger Group:


After a disastrous event that caught Mindanao off guard, especially the provinces of Davao Oriental and Compostela Valley, USAID thru the Louie Berger Group contracted GEOS Inc. and other experts to conduct a vulnerability assessment over the two aforementioned provinces. GEOS lead the task of simulating flood hazards, validating the flood simulation results and compilation of other hazard maps from respective government agencies.

Provincial Conference on Disaster Risk Management and Climate Change contracted by USAID thru The Louie Berger Group: 


As a follow-on activity for the previous vulnerability assessment, GEOS was contracted to organize a two-day conference for each of the two aforementioned provinces with Mayors, DRRM officers, Governors and Baranggay officials as target audiences. GEOS produced maps, kits and booklets that the participating guests can use to further the enhancement of their disaster preparedness. Small group sessions were also conducted to arm personnel with knowledge on the basic use of GPS, map reading, the government disaster response structure, etc.

Preparer of Engineering Geological and Geohazard Assessment Report (EGGAR) for Ayala Land Incorporated (ALI) and Makati Development Corporation (MDC)


  • Araza Property
  • MBAI Property
  • FTI Property
  • Dionido Property
  • Buntog Propoerty (Nuvali, Calamba)
  • Alcantara Project (Davao City)
  • Lipa Core Project
  • XO Propoerty
  • Lagundingan Project 


 EGGAR is also a form of technical due diligence (TDD) required from land and propoerty developers. Above other technical facts being studied about the property, it also highlights the past and possible hazards that affected the land and might affect the property in the future; which, in response the developer incorporates this study in their plan. GEOS Inc. conducted and is continuously conducting EGGA reports for the Makati Development Corporation and Ayala Land Incorporated.

Building instrumentation (seismometers) for the Zuellig Building (Makati)


According to the Section 105.2.1 of the National Structural Code of the Philippines, "Unless waived by the building official, every building in Seismic Zone 4 over 50 m in height shall be provided with not less than three approved recording accelographs. The accelographs shall be interconnected for common start and common timing". The accelographs/accelerometers or seismographs/seismometers are building instruments used for seismic data recording. One of its primary functions is to store earthquake data acquired from the movement of the building which can be used for post earthquake data interpretation. With it, engineers can conclude if the building is fit for reoccupancy after an earthquake.

GEOS Inc. is the official distributor of Kinemetrix products and have already installed seismometers in several structures such as the Zuellig Building.

Unexploded Bombs and Ordnances detection using the Ground Penetrating Radar (GPR) in the Diosdado Macapagal Airport and Texas Instruments Development Site subcontracted by AGA Development and Construction Corporation:


A GPR survey was performed by GEOS Inc. to detect anomalies or unexploded bombs under the ground.

Way back, Clark used to be a military base of the U.S. Army. During the second World War, Japanese Imperial forces launched aerial attacks in several parts of the Philippines, including Clark, one of the military bases of the Americans. Fortunately or unfortunately, some bombs did not explode. Due to this fact, present land owners in Clark get experts to detect if there are hazardous substances such as bombs under their properties before even constructing.

The GPR sends signals penetrating 3-5 meters from the surface depending on ground conditions. Buried anomalies are detected when signals are sent back; meaning, there is something that reflects the signal back. With this indication, the location of the anomalies are pinpointed and then dug by site personnel.
