Sr. Mechanical Quantity Surveyor

Role Summary

The Mechanical Quantity Surveyor will be the functional lead between traditional cost management practices, field execution and our evolving construction technology and data strategy. Working out of our Vaughan office, this role will combine deep technical and commercial understanding with field-based verification, data integrity, and process improvement.

Why This Role Matters to Modern Niagara

The Mechanical Quantity Surveyor plays a critical role in strengthening the integrity, accuracy, and reliability of project cost controls: an essential foundation for delivering profitable and predictable mechanical construction projects. In an environment where labour productivity, work‑in‑place verification, and cost certainty directly influence both project and organizational performance, this role ensures that financial and operational decisions are based on verified field data rather than assumptions. By combining technical expertise, on‑site inspection, and modern data practices, the Quantity Surveyor identifies risks early, improves forecasting accuracy, and enables project teams to plan and execute with greater confidence. Their influence extends beyond individual projects, helping reestablish best practices, modernize systems, and embed a culture of transparency and continuous improvement across the company. Ultimately, this role safeguards the organization’s financial health while driving operational excellence and long‑term competitiveness.
