If you’re a piping or mechanical estimator wondering what your next move looks like, read on. This could be the career-defining step you’ve been waiting for.

About District Mechanical

Are you a piping estimator who wants to do more than run take-offs and have a real hand in shaping how a company grows in a new market? District Mechanical is looking for a Piping Estimator ready to take the lead on tendering in Calgary, and to grow alongside a company where your work is seen and valued.

District Mechanical is an employee-owned mechanical contractor headquartered in Edmonton, Alberta, and it is growing its team in Calgary. The company delivers complex institutional, commercial, healthcare, industrial and large-scale residential projects across Alberta, and it has significant opportunities for continued growth. This is an prospect to join a hands-on, entrepreneurial environment where initiative is valued, ideas are welcomed, and individual contributions make a meaningful impact.

Reporting to the VP Procurement, you will lead piping estimates and tenders for projects in Calgary and the surrounding area. You will work closely with the estimating, operations, project management and leadership teams, from the first review of a bid package through to a smooth handoff to the operations team once a project is won. This role is based in Calgary, but District Mechanical is open to considering the right candidate in Edmonton.

Who You Are





You are a piping or mechanical estimator with experience on commercial, institutional, multi-family, industrial or similar construction projects. You know that a missed scope gap can sink a job’s margin and a sharp value engineering option can win it, and you take pride in getting both right.

You know piping systems inside and out, including plumbing, hydronics, process piping and equipment connections, and you understand how they fit with the rest of the mechanical scope. You can build a complete estimate from drawings, specs and addenda, read a subcontractor quote for what it leaves out, and think through labour productivity, sequencing and risk with confidence.

You know the Calgary construction market, or want to, and you enjoy building relationships with suppliers, trade partners and clients. Most importantly, you take ownership of your work and are interested in building a long-term career with a company where your growth can align with the growth of the business.

Key Responsibilities

This role will evolve based on your experience, strengths, and career objectives. Reporting to the VP Procurement, you will be accountable for:

Bid Review and Estimating

- Bid Package Review: Lead the review of bid packages, drawings, specifications, addenda and tender requirements to determine scope, inclusions, exclusions, risks, opportunities and required resources.




- Estimate Preparation: Prepare accurate and complete estimates, including material take-offs, labour productivity, equipment, rentals, indirect labour, subcontracted scopes, general requirements, overhead and profit.
- Piping and Mechanical Scopes: Estimate piping and plumbing, hydronics, equipment, insulation, fire stopping and related mechanical scopes, and coordinate pricing for HVAC, sheet metal, controls and other subcontracted work.
- Risk and Value Engineering: Identify drawing conflicts, specification concerns, constructability issues, scope gaps, cost-saving opportunities and value engineering options during tender.

Pricing and Tender Submission

- Supplier and Subcontractor Pricing: Issue detailed bid packages to suppliers, vendors, subcontractors and trade partners, and review their quotations for completeness, exclusions, scope gaps, schedule impacts and alignment with tender documents.
- Site Visits and Pre-Bid Meetings: Attend site visits, pre-bid meetings, project showings and tender walkthroughs in Calgary and the surrounding area.
- Proposal Preparation: Prepare tender proposal requirements, including bid forms, breakdowns, alternates, bonding and insurance requirements, schedules, org charts, resumes, company experience, craft rates and mark-ups.

- Bid Close-Out: Confirm scope coverage, pricing status, addenda acknowledgements, tender forms, exclusions, qualifications and final submission requirements.
