Deciphering Construction Estimating Services: Estimators vs. Quantity Surveyors

 In the realm of construction estimating services, the distinction between estimators and quantity surveyors is pivotal but often misconstrued. Both roles contribute significantly to construction projects, yet they serve distinct purposes. In this blog post, we unravel the nuances that set estimators and quantity surveyors apart, assisting you in determining the most suitable fit for your needs.

What Does an Estimator Do? An estimator is a crucial figure in the construction planning process, specializing in providing initial cost estimations pivotal for winning tenders. With a profound understanding of construction technologies, estimators navigate blueprints, incorporate environmental considerations, and ensure accurate estimates. Their role extends to fostering on-time and on-budget project deliveries.

What Does a Quantity Surveyor Do? A quantity surveyor, a qualified professional and industry advisor, meticulously advises and monitors construction costs throughout a project’s lifecycle. Beyond project completion, they may contribute to tax depreciation schedules and replacement cost estimations for insurance purposes. Attaining membership at the Australian Institute of Quantity Surveyors (AIQS) underscores their compliance with industry standards, maintaining a high-quality standard of surveying.

Similarities: independent cost estimator and quantity surveyors converge on a shared objective — facilitating the seamless execution of projects. Through their respective expertise, both professions craft reliable, accurate estimates that mitigate financial risks and provide enhanced cost control for project managers. This collaborative effort empowers builders to realize their project visions within predefined schedules and budgets.

Differences:

Projects Undertaken:

• Quantity surveyors are frequently involved in larger and more intricate projects, often serving both public and private sectors due to their AIQS accreditation and extensive skillset.
• Estimators, conversely, are more commonly engaged in residential and smaller commercial projects, although exceptions exis

Priorities:

• Estimators prioritize providing accurate and timely cost estimations, with the primary goal of aiding clients in winning tenders.
• Quantity surveyors prioritize furnishing the Bill of Quantities (BOQ), detailing material and labor quantities essential for project completion. The BOQ resolves potential discrepancies in tender documents, facilitating fair and accurate calculations of construction costs.

Roles Played:

• Quantity surveyors offer support before, during, and after a construction project’s lifespan.
• Estimators are predominantly involved in the pre-project phase, specifically during tendering. Subsequently, they may extend ongoing support, offering fresh cost estimates as new circumstances arise.

In essence, while both estimators and quantity surveyors contribute indispensably to project success, their areas of focus, project scopes, and timelines differ. Understanding these distinctions empowers stakeholders to align their construction estimating needs with the specialized expertise each role brings to the table.
