* Develop various types of estimates from conceptual class V estimates for proposals and early conceptual studies, to detailed estimates for ongoing projects utilizing estimating tools, databases and spreadsheets.* Responsible for all aspects of the estimate (e.g. establish the estimating scope of work, prepare estimate methodology and basis of estimate), as well as produce the overall estimate schedule identifying all deliverables and interfaces with other disciplines.* Coordinate and monitor input from process engineering, discipline lead engineers, procurement, contracts and construction to ensure a timely completion.* Establish key parameters associated with the overall quality and accuracy of the estimate such as: Equipment and material pricing guidelines, material take-off and other allowances, escalation philosophy, and site labor productivity factors.* Assemble final estimate packages; conduct detailed analysis of completed estimates including benchmarking against similar completed projects and reconciliation of completed estimate to prior estimates
