Geotechnical Investigation for LRT Extension
Date Completed: January 2021
This was one of the most challenging projects when Teragrail started. The investigation was only limited to four (4) hours to avoid disrupting the daily operations of LRT. So the team had to set-up, drill and dismantle in this time span; not to mention all the safety preparations Teragrail had to go through since the Contractor was a foreign company.

Geotechnical Investigation of 50 Boreholes
MANILA BAY, MANILA
Client: Cargon Mining Corporation
Date Completed: November 2021
The purpose of this investigation was to check for the suitability of the Manila Bay seabed to be used as backfill materials. TGG Mobilized two (2) barges, four (4) drilling teams, and two (2) drilling rigs for this project. The TGG team was able to complete this project in about four (4) months. The boreholes ranged from 10-m deep to 40-m deep. Continuous undisturbed drilling was done from 0.0-m to 15.0-m while SPT Sampling was done from 15.0-m to 40.0-m depth. This was a 24-hr operation.
Construction of Micropiles and Bored Piles for a Four (4) Storey Building
INTANDENCIA, INTRAMUROS, MANILA
Client: M.E. Sicat Construction Corporation
Date Completed: Ongoing
TGG is currently undergoing the construction of 40+ micropiles and 10+ bored piles for a four (4) storey building in Intramuros. TGG is responsible for all the drilling, welding, concrete pouring and jet grout works. Prior to the start of construction, TGG also conducted the Geotechnical Investigation and Evaluation for this project. In addition, TGG also conducted Ground Penetrating Radar works to check for underground utilities. This is for phase 1 works. TGG will also be commissioned to do the micropile and bored pile construction works for phase 2 which entails about 500 micropiles and bored piles in the area.
