Cost Estimator - Construction Projects

Summary: The Cost Estimator will work closely with the Facilities Management Department staff to generate construction cost and schedule estimates for design and construction projects at varying stages of development. Estimate types will range from high level parametric for long term planning, to detailed take-offs for construction cost. Estimate values will range from a few thousand to several million dollars.


  • Using written scopes of work and/or construction documents (drawings) generate timely cost estimates and analyses for design and construction projects at various project stages, including Rough Order of Magnitude and budget assessments during planning and detailed take-off estimates before and during construction. Produce succinct reports for customers with documented assumptions and constraints for the basis of estimates.
  • Develop and maintain a master cost database for estimating and collaborate within the Facilities Management Department to optimize unit cost baselines for design and construction projects. Develop and maintain a cost history tracking system for design and construction projects.
  • Breakdown cost estimates according to appropriate financial guidelines such as overhead, capital, work breakdown structure and/or schedule of values by system or activity. Assist Project Managers and Construction Managers to review and evaluate construction change orders and schedule changes. Review applications for payment on identified projects, calculate and track earned value for these projects.
  • In partnership with the Schedule Analyst, develop, maintain and distribute to management and relevant staff a summary report of project cost estimates with resource analysis for the department's project portfolio. Communicate with various stakeholders to provide appropriate level explanations and conduct follow-up lessons-learned discussions when needed.

Required Qualifications:

  • Bachelor's degree in a related field or equivalent (Associate's degree with 2 years of professional experience or equivalent) with minimum 2-5 years of experience as an estimator for a general contractor or construction management company with general knowledge of estimating for all trades.
  • Proficiency using MSOffice (Word, Excel, and PowerPoint) and estimating software (R.S. Means, Tradeline, Tririga, Tradeline, ProEst, etc.).
  • Background in building design, engineering and construction (new construction and/or renovation).
  • Candidate shall be resourceful with a high level of customer service acumen and ability to work closely with design and construction teams.

Desired Qualifications:

  • Project management, construction management experience.
