• Manage and work alongside other HSR engineers, oversee work.
• Develop overall program to ensure compliance to government regulations and approved plans for construction of HSR. • Lead meetings to coordinate work and compliance at multiple levels with local staff, Chinese partner firm staff, Construction company leadership and staff, and also with Chinese government officials overseeing HSR train construction. • Meet regularly (at least weekly) with the Chinese partner engineering firm's CSE and staff to strategize on process improvement, coordinated reviews and inspections. • Kept a daily detailed journal, developed a sophisticated Excel-based computerized inspection database complete with photos and video log of each relevant inspection. • Inspect 40 major construction sites (tunnels, bridges, at-grade track, piers, and passenger stations). • Responsible to monitor performance at all levels of inspection and construction, ensuring compliance to all regulations and schedule. • Prepare weekly inspection summary reports to the Chinese Government authorities over high speed rail (HSR) construction. His reports were detailed with graphics and Chinese Mandarin text as well as English text, and contained recommendations to the government on where improvements were necessary. These also documented training sessions, and other meetings to improve effectiveness. • Filed CSE NOTICE and STOP ORDER reports as needed to ensure construction company compliance to government regulations on the site whether it be in the tunnels, at the batching plant, the girder and viaduct yard, foundation construction, or pier assembly, etc. Below are a sampling of some photos and videos of on-site inspections at pier construction, foundation construction, tunnel construction, box culvert construction, rebar assemblies, viaduct construction using viaduct molds, bridge construction. |

Tunnel Team Inspection. Reinforcing Steel Arch inspection. Soil is hard rock. Blasting taking place. Arch starts at upper bench and progresses down to lower bench (pictured) where bottom of arch is installed.
|
TUNNEL FINAL WALL CONSTRUCTION. After Phase 1 shotcrete and steel arch is installed, this second concrete wall is constructed inside of it, adjacent to the shotcrete, to make a rebar reinforced very thick concrete shell inside, strong and smooth surface.

TUNNEL CONSTRUCTION. Tunnel Team Inspection. Tunnel Outer-edge Wall, 1st Phase Shotcrete Containment. Reinforcing Steel Arch inspection. Pace can not exceed safety requirements, and thickness of shotcrete must meet standards. Concrete must not be dry mix.

The very first step to viaduct pier construction: the drilling of eight 1 meter diameter holes at least 10 m deep (depending on soil) to house a rebar cage and be the bottom anchor (usually 8) for a large foundation block, topped by a pier of varying height (at least high enough for regular travel beneath on these farm lands).

Atop the main pier, which will support the future bridge crossing major road. Each of these piers are supported by rebar reinforced concrete foundations connected further to deep rebar reinforced pilings all dependent on soil conditions and/or rock.

|
PIER CONSTRUCTION for VIADUCT BRIDGE. After pouring pier anchors, workers remove concrete to expose rebar cage. This worker is not wearing helmet or eye protection, a common problem that is reported. After all concrete is removed from top, the rebar will be connected to future rebar cage built in the square hole for the main foundation, then after curing, a future pier is constructed above that, then future viaduct above that. A four-step process.
