Quantity take-offs (QTO) are a detailed measurement of materials and labor needed to complete a construction project. They are developed by an estimator during the pre-construction phase. This process includes breaking the project down into smaller and more manageable units that are easier to measure or estimate.

2024年1月1日 · This paper introduced a novel BIM-based QTO/QPC system, particularly for the structural and architectural disciplines, to automatically calculate, list, extract, store, and visualize the QTO outputs after improving their precision and consistency.

2017年1月1日 · Building Information Modeling (BIM) software has allowed the industry to begin to move toward BIM-based quantity take-off (QTO) and estimating [1]. Autodesk Revit, Bentley, Vico, Assemble and Autodesk Navisworks are just a few of the programs allowing the industry to shift toward BIM-based QTO and estimates.

What Is A Quantity Takeoff In Construction? A quantity takeoff, also known as a construction takeoff, is the process of analyzing drawings and models to list and measure the materials and labor needed to complete a project. Companies use QTOs to estimate costs and define accurate project budgets.

QTO是工程总价估算中最沉闷和耗时的部分。 需要经过大量的资料搜索来计算出之后阶段各方面需求的数量需要的价格。 工程管理中的quantity takeoff是什么意思Quantity Take-off（工程估算） 是指一种细节化的计算一个工程需要的材料和人力的方式。 工程估算由评估师在施工前阶段完成研发。 这种计算是用来做投标范围评估的。 评估师根据.

2018年9月20日 · Cost estimation in the construction industry is generally done by performing a quantity take-off (QTO) based on the available information within the current project phase. Estimators review blueprints and additional requirements to calculate the quantities of the construction work.

2013年11月1日 · While automatic Building Information Modeling (BIM) based quantity takeoff is one of the potentially most important and profitable applications for BIM, it is still generally underexplored how BIM...

What is Quantity TakeOff? A Quantity Take-Off (QTO) is the process of determining and measuring the quantities of materials required to complete a construction project. It involves extracting detailed quantities from project blueprints, …

BIM-based Quantity Takeoff (QTO) can extract the geometric data and semantic properties of architectural elements to determine a quantity. Efficient data management and rapid decision-making have been attained with the AEC sector’s transition from CAD to BIM .

In construction, quantity takeoff (QTO) is a foundational step that directly impacts project costing and budgeting. By determining the materials, labor, and equipment needed for a project, quantity takeoff provides the basis for accurate estimates and helps prevent unexpected costs or delays.
