Professional experience

Thirty years measured through the work.

Major infrastructure surveying created the field judgement now applied to earthwork takeoff, cut and fill calculations and CAD documentation.

1991-1999

Hydropower

Ertan Hydropower Station

Engineering surveying

Long-duration major-infrastructure work established a practical foundation in control, measurement and field coordination.

1999-2000

Tunnel

TBM tunnel project

Tunnel surveying work

Alignment-led tunnel work reinforced disciplined checks, geometry control and the importance of traceable field records.

2000-2003

Hydropower

Longtan Hydropower Project

Project surveying work

Continued major-project surveying expanded experience across complex structures, terrain and construction interfaces.

2003-2010

Hydropower

Xiluodu Hydropower Station

Project surveying work

Multi-year infrastructure delivery deepened judgement around drawing interpretation, measurement basis and reviewable outputs.

2011-2020

Airport

Luanda airport construction

Construction surveying work

Large site and transport-infrastructure work added international project context and broad earthwork coordination experience.

2020-present

Earthworks

Earthwork quantity and site work

Quantity calculation and technical support

Current work applies decades of field judgement directly to cut/fill, quantity takeoff, sections and CAD deliverables.

Field context

The work was larger than a portrait.

These scenes make the scale and working methods easier to understand. Each is a visual reconstruction based on a verified experience record, not a claim that an archival photograph survived.
