What You'll DoThe Construction Technical Office (CTO) is a newly established team within CJV, created to bridge the gap between design and construction across our active major civil sites. The Construction Coordinator supports the CTO by coordinating engineering services during construction at station, grade separation, and bridge modification sites, acting as the day-to-day technical interface between the construction team and design consultants.
This is a primarily site-based role. You will be embedded in the construction environment, helping the site team navigate design documents, track technical submissions, and resolve field issues in a timely manner.
Key Responsibilities
Provide day-to-day coordination of engineering services between site teams and design consultants across active station construction sites.
This is a site-based role that will coordinate closely with construction teams to monitor progress, identify emerging technical issues, and support timely resolution.
Facilitate technical discussions and coordination meetings between construction supervisors, designers, and other project stakeholders.
Support constructability reviews of design packages in close collaboration with the construction team, identifying practical issues early.
Prepare basic field sketches and mark-ups using AutoCAD to support field queries, design clarifications, and site communications where required.
Coordinate the review and tracking of Inspection and Test Plans (ITPs), Requests for Information (RFIs), Site Instructions (SIs), and shop drawings between the site and design consultants.
Monitor the status of outstanding submissions, elevate overdue items, and maintain trackers to keep the CTO team and site team informed.
Ensure the construction team has access to the current approved revision of all design documents, and that superseded drawings are promptly removed from circulation.
Support interface management between design packages, construction sequences, utilities, and external stakeholders.
Coordinate across multiple engineering disciplines (civil, structural, architectural, mechanical, electrical) to support integrated delivery of station works.
Ability to read and interpret multi-disciplinary drawings and specifications, identify coordination gaps, and communicate issues clearly to the relevant designers or site supervisors.
Proactively identify, monitor, and escalation risks and issues that may impact construction progress or quality at station sites.
Support the management of design changes, including tracking impacts to scope, cost, schedule, and risk.
Prepare and maintain dashboards, logs, and visual trackers to monitor outstanding RFIs, ITPs, SIs, and other technical submissions.
