Senior Preconstruction Estimator

ADI Development Group ranks among Canada's most forward‑thinking real estate development, construction management, and investment firms. With more than 4,000 units and $3 billion in built value across the GTHA, we’re on a bold mission to transform the home‑buying experience—delivering better‑quality homes faster and more efficiently than anyone else in the market.
The people who thrive at ADI are passionate about their work, decisive by nature, and genuinely committed to growth. We push each other to think differently through honest, respectful dialogue—and when a decision is made, we align and execute as one team. Shared challenge. Shared learning. Shared wins.
The RoleWe are looking for a seasoned Preconstruction Estimator to join our expanding team. You will take ownership of the full estimating process—from initial feasibility through construction documentation—serving as a key voice in how ADI’s projects are structured, designed, and financially positioned. Working alongside internal development, design, and construction teams as well as outside consultants, you’ll help ensure every project is economically sound, competitively priced, and set up for precise execution.
If you’re an estimator who does your best work in a high‑energy, entrepreneurial setting and wants a real seat at the table on major high‑rise and mixed‑use projects, this is the role for you.

Develop conceptual and order‑of‑magnitude estimates from feasibility stage onward to guide design and proforma development
Conduct due diligence cost analysis for land acquisition, including cost‑per‑suite and cost‑per‑GSF benchmarking
Model multiple design and massing scenarios to advise on cost implications before significant design investment is made
Estimate Development & Quantity Surveying
Prepare detailed quantity surveys, takeoffs, and estimates across all design stages from schematic through IFC
Break down projects into elemental scopes from both complete documentation sets and preliminary designs
Maintain and refine an internal cost database, benchmarking historical data and tracking live market pricing

Project Collaboration & Value Engineering
Facilitate VE workshops with design and construction teams, presenting cost alternatives and trade‑off analyses
Review constructability with design teams to identify cost risks early in the design process
Track budget alignment as design evolves, flagging material variances against proforma assumptions
Assist with Division 1 cost management and cash‑flow oversight
Proforma & Cost Reporting
Maintain hard cost documentation at each major design milestone
Prepare executive‑ready cost reports and estimate summaries for internal leadership
Monitor labour and material escalation trends to keep cost intelligence current and competitive
