01
Engineering Geology Office Building — Geotechnical Foundation Investigation
Completed September–October 2026 for the Department of Mineral Policy and Geohazards Management, with Missionary Works Ltd as head contractor. ESPNG delivered the geotechnical foundation investigation for the Engineering Geology Office Building reconstruction — test pitting, DCP testing, soil logging and sampling, laboratory testing, and foundation design parameters revised following independent design review.
02
Agogo Production Facility & Usano — Groundwater Investigation
Completed August–September 2026 for Santos PNG — groundwater investigation at Agogo Production Facility and Usano to support contingency water-supply planning during El Niño dry conditions. ESPNG undertook desktop review, GIS mapping, a 13-line PQWT geophysical survey, interpretation and prospective drilling-target selection to inform further evaluation of alternative groundwater sources.
03
Offshore Geotechnical Drilling — LNG Plant Site
Offshore geotechnical drilling and drill supervision at the LNG plant site in Caution Bay — subsurface investigation supporting marine and pipeline foundation design for one of PNG’s largest resource projects.
