GEOTECHNICAL ENGINEERING PORTFOLIO

Al Zour Refinery – Kuwait

TWE was retained by the joint venture FDHJV, comprised of Fluor Ltd., Daewoo Engineering and Construction Co. Ltd., and Hyundai Heavy Industries to provide geotechnical engineering services for the Al Zour Refinery (ZOR) in Kuwait.  ZOR is located approximately 80 km south- southeast of Kuwait City and when completed, will cover 16 sq. km and will have a total refining capacity of 615,000 bpd.

TWE’s scope of services included reviewing previous geotechnical studies performed by others and providing field observations during supplemental geotechnical studies including test borings,   downhole seismic surveys, cone penetration testing, test pits, and field electrical resistivity surveys.  We also reviewed laboratory testing performed by the Kuwaiti geotechnical subcontractor, INCO Laboratories.   Our team also conducted energy calibrations for the equipment used to perform SPT.

Belfiore High Rise Condominium – Houston, TX. Inter-Pier, LLC

This project included the construction of a new 26-story condominium tower. TWE performed geotechnical engineering services including field exploration, laboratory testing, and a report documenting our findings and providing geotechnical design and construction recommendations.

Sabine Pass LNG Cameron Parish, Louisiana (Approximately $1.2B)

TWE performed Geotechnical, Instrumentation, and Materials Testing services for this LNG receiving terminal. The project included the construction of a berth/marine terminal, two degasification units, impoundment basins, office and control room facilities, and five (5) LNG Tanks.

Grand Parkway Segment D Proposed Three Overpass Bridges

TWE performed Geotechnical services for the proposed construction of three overpass bridge structures and associated mechanically stabilized earth (MSE) retaining walls, light poles and unmanned toll booth structures.
