Quantity Surveyor

Job Description:
Quantity Surveyor

Specific Responsibilities

• Prepares material takeoffs on assigned contracts, projects, or programs from engineering drawings, plans, and specifications.


• Reviews takeoffs prepared by others to check for completeness, appropriate definition, and accuracy.


• Prepares detailed breakdown structures (WBS) for contracts, projects, or elements of a program sufficient to define the scope to be delivered.


• Defines the specific scope intended by the contract documents, project development requirements, and/or the program element components, systems, and subsystems.


• Prepares and summarizes the bases of estimate (BOE) development, including estimate scope, estimate method of development, pricing utilized, labor, material and equipment rates included in the estimate, assumptions and exclusions, escalation, parametric comparisons using previous estimate data from similar projects, estimate quality control (QC) review and results, and estimate conclusion and recommendation.


• Delivers a complete and comprehensive estimate of probable cost based on the proposed contract documents inclusive of contract terms and conditions.


• Defines, details, and estimates the cost of contract general conditions and job cost in compliance with the planned execution to accomplish total contract delivery.


• Utilizes parametric historical estimate data to develop a reasonable estimate of probable cost, based on a high level of scope definition and preliminary intent for a capital asset in relation to an order of magnitude (PM) development.


• Defines the intended scope, function, and output of a specific system, service, or asset using the basic "top-down" WBS development approach.


• Utilizes the "bottoms up" approach in the development of probable contract cost, and compares that cost with data from previous contracts similar in nature when the estimated task required detailed development.


• Develops scope sheets and request for bid or quotation from potential service providers, inclusive of internet, telephone, and/or written provided data.


• Assists the Estimating Leads for historical data and estimate database management with the accumulation, evaluation, and documentation of cost data retrieved from completed discrete design and/or construction contracts, inclusive of work activity, delivery means and methods, productivity, activity durations, supervision and craft man-hour utilization.


• Reviews contract documents to access contract risk and significant exposure to estimated cost if potential risks are experienced. Assigns reasonable maximum cost and schedule exposure resulting from potential risks.


• Provides technical guidance to lower-level Associate Estimators.


• Collaborates with small estimate teams comprised of other Estimators and Associate Estimators with the outcome being a final deliverable that meets Customer and Client requirements and expectations.


• May deliver quality-controlled estimates for the project/program assigned.


• Performs other responsibilities associated with this position as may be appropriate.
