Tunnel Inspector at Hatch

The Project Involves The Following Construction And Conditions

Serve as an experienced tunnel inspector, meeting the required responsibilities, qualifications and experience, who reports to Hatch’s construction management team of senior, engineers and managers (ie. Engineer’s representative (ER), project engineer (PE), construction manager (CM) or project manager (PM)) on a tunnel construction project.

• Tunnel: The tunnel consists of a 3.5 km long, 3.0 m diameter tunnel in hard rock, located 70 m underground excavated and constructed by drill & blast and tunnel boring machine (TBM) tunnelling methods. Tunnels will be initially supported by rock dowels and steel wire mesh followed by a final lining of shotcrete.
• Shaft: The central shaft consists of a 35 m deep, 4.0 m diameter shaft sunken and constructed by drill & blast methods. Shaft will be initially supported by rock dowels and steel wire mesh followed by a final lining of shotcrete.
• Portals: Tunnel portals will be constructed into adjacent sidehills at both the entry and exit portals and on-line with the tunnel grade. Portal ground support will consist of rock dowels and tensioned rock anchors for the slopes surrounding the portal areas.
• Pipelines: Dual sanitary HDPE pipelines will be constructed in the completed tunnel and shaft.
• Ancillary Structures: Gate/valve vaults and manholes consisting of conventional reinforced concrete.
• Location: East London, South Africa or Greater Area of.
• Typical surface and underground construction site environment with safety hazards including extreme adverse weather conditions, hot and cold temperature (5°C - 30°C) atmospheric conditions, atmospheric dust, wet conditions, high noise levels, animal attack, working at heights, rockfalls, slips, trips and falls.

• Assist to establish and maintain documentation of non-conforming work. Assist in tracking corrective measures to resolve any non-conforming work.
• Assure that contractor's as-built records are monitored for accuracy and completeness, collected at end of the project, and forwarded to engineer’s representative.
• Assist with geological mapping of the tunnel face and sidewalls by the contractor and the Employer’s specialty geotechnical engineering consultant.
• Verify that tests and inspections are performed, witnessed, and documented in accordance with approved procedures. Help prepare and resolve non-compliance notices.
• Assist with the preparation of weekly and monthly construction progress reports for Employer.
• Other duties as assigned.
