Company Objective:

Dr. G. Sauer & Partners Corporation (DSP) has a record of delivering high quality and innovative tunnel design solutions for public and private underground infrastructure. We deliver under tight programme controls by working efficiently with highly qualified and motivated team members.

Purpose of the role:

The Principal Tunnel Engineer will head the SEM supervision team and will be the link between the local Managing Director and the delivery of design and/on-site supervision projects. For on-site projects his role is to set up the project team, implement company and site-specific procedures. The candidate needs to be able to step into the role of the Senior SEM Engineer on site who heads the SEM supervision team on a specific construction site.

The Principal Tunnel Engineer manages the site supervision team, which includes the SEM/Geotechnical Engineers and the Senior SEM Inspectors, to ensure compliance with the design and to provide QA/QC oversight as far as it concerns the excavation and support work of the mined stations. The Principal Tunnel Engineer works closely with the contractor’s construction and engineering team and needs to find agreement with the Contractor’s Tunnel Manager. In the field the Principal Tunnel Engineer will evaluate and assess geologic and hydrologic conditions or ground support categories and approve or if required, direct use of ground support measures. The job holder will also coordinate with the Contractor, track the construction schedule and provide input to improve production, quality, safety and logistics, based on information received from the Senior SEM Inspectors, if required. The Principal Tunnel Engineer will produce a monthly status report and attend all required meetings.

In a design project the Principal Tunnel Engineer will take the lead in the SEM / Tunnel specific design effort. The successful candidate will implement the company and project specific design processes, working closely with the Technical Director and other Senior Staff members for the efficient production of tunnel designs (drawings, analysis, specs, reports).

The Principal Tunnel Engineer will also assist the Managing Director in Business development and procurement activities, representing the company and developing bidding strategies and supporting documentation.
