Estimated Quantities in Measurements and Calculations in Resources and Infrastructure Industries
Posted by SkillMaker in Jan, 2025
What is a concise description of estimated quantities in measurements and calculations?

In the context of the resources and infrastructure industries, estimated quantities involve determining approximate values or dimensions for various components of a project. This process is critical in the planning and execution phases, ensuring that materials and resources are allocated efficiently.
Why do people in enterprises need estimated quantities when carrying out measurements and calculations?
Estimates are crucial for budgeting, planning, and resource allocation. By accurately estimating the quantities needed, enterprises can reduce waste, manage costs effectively, and ensure the timely completion of projects. It facilitates informed decision-making and strategic planning for project managers and stakeholders.
“Estimated quantities form the backbone of efficient project management in the RII, enabling precision in planning and execution.”
What are the key components or elements of estimated quantities?
Key components include:
- Data Collection: Gathering necessary data from plans and specifications.
- Unit Conversion: Converting measurements to appropriate units for consistency.
- Calculation Methods: Applying mathematical techniques for accurate estimates.
- Adjustments: Factoring in contingency and wastage allowances.
What key terms, with descriptions, relate to estimated quantities?

Registered Trademark®
- Bill of Quantities (BOQ): A document listing the materials, labour, and other resources required.
- Takeoff: The act of extracting quantities from construction drawings.
- Cost Estimation: Predicting the financial expenditure of a project.
- Allowance: Additions to quantities to accommodate uncertainties.
Who is typically engaged with operating or implementing estimated quantities?
Quantity surveyors, project managers, estimators, and site engineers are the primary professionals involved in estimating quantities. These roles ensure measurements are accurate, relevant data is considered, and estimates reflect realistic expectations for the project lifecycle.
How do estimated quantities align or integrate with other components of Resources and Infrastructure Industries in Australia?

Estimated quantities are critical in aligning with design, procurement, and construction phases. They ensure that all stages function within budget and timeline constraints, facilitating coherent project execution and management within the Australian Resources and Infrastructure Industries.
Where can the student go to find out more information about estimated quantities?
What job roles would be knowledgeable about estimated quantities?
Roles include:
- Quantity Surveyors
- Project Managers
- Estimators
- Site Engineers
- Construction Managers
What is estimating quantities like in relation to sports, family, or schools?

In sports, estimating quantities is similar to a coach preparing strategies based on the team’s strengths and statistics. In a family setting, it equates to organising a budget or weekly shopping, where estimating needs helps maintain balance. Within schools, it mirrors assessing the resources needed for activities or events, ensuring all requirements are met within resource limitations.
