What You’ll Do:

As a Senior Mechanical Estimator, you’ll be responsible for owning the estimating process from initial bid through to final submission. You’ll manage complex estimates independently, coordinate cross-functional inputs, and play a lead role in winning work for our business. You will be expected to work closely and collaboratively with the entire estimating and operating teams to effectively develop the best-in-class proposals.

This role supports bid strategy development, mentorship,



and close collaboration with operations and project management teams.

This is an office-based role with occasional site visits as required.

Responsibilities will include, but are not limited to:

- Lead end-to-end estimating efforts on mechanical infrastructure projects.
- Provide mentorship and oversight to junior estimators, reviewing their work and supporting their growth.
- Develop accurate, detailed, and competitive estimates that include labour, materials, equipment, and subcontractor pricing.
- Interpret tender documents, design drawings, and technical specifications to define project scope and cost implications.
- Preparation of quantity take-offs, material costing sheets, and final estimate documentation in estimating software (Accubid or similar).
- Identify risks and opportunities in project scopes and propose strategic pricing approaches.
- Coordinate with internal stakeholders (engineering, operations, procurement) and external subcontractors to ensure accurate and timely inputs.
- Ensure all estimates are aligned with project goals, client requirements, and company standards.
- Attend site visits as needed and lead estimate reviews prior to submission.
- Contribute to the development of estimating tools, templates, and best practices to improve accuracy and efficiency across the department.

What We're Looking For:

We’re excited to meet candidates who have:

- Bachelor’s degree in Mechanical Engineering or Diploma in Mechanical Engineering Technology, or equivalent combination of education and experience.
- Minimum 5+ years of experience in estimating construction projects,



including leadership in developing large-scale bids.
- Proficiency with Microsoft Excel, estimating software, and digital take-off tools; experience with Accubid, Bluebeam, or similar systems is an asset.
- Demonstrated ability to independently manage high-value, multidisciplinary estimates under tight deadlines.
- Solid understanding of construction contracts, risk evaluation, and cost modeling.
- Strong leadership, collaboration, and interpersonal skills.
- High attention to detail and strong analytical thinking.
- Ability to thrive in both independent and team-driven environments.
