Quantity takeoff in construction estimates the quantities for a contract from the drawings and construction plans to forecast the upcoming construction costs. An accurate quantity takeoff helps the team stay on budget while ensuring time management and effective cost tracking.
Quantity takeoff is a complicated process that is prone to errors and reworks. They are made right from the start, i.e., during preconstruction, and are frequently adjusted throughout the estimation process.
This article discusses a few tips to improve the quantity takeoffs during construction cost estimation.
Few leading strategies that can enhance the efficiency and accuracy of the quantity takeoff procedure are mentioned below.
Performing quantity takeoffs manually is extremely time-intensive. In the manual approach, the estimators commonly use spreadsheets and excel templates to calculate quantity takeoff. This process also carries high possibilities of human error and risk while inputting the data.
By using construction software, the quantity takeoff procedure is performed more accurately within a fraction of time. In addition, all takeoff software comes with customization options that can be adjusted by the estimator and used as per requirements.
The use of digital quantity takeoffs helps to perform the following task involved in manual takeoffs within a fraction of time:
BIM for quantity takeoffs is a step beyond the above-mentioned pure digital takeoffs. For example, Assemble, eTakeoff, and Cubit are some examples of BIM quantity takeoff software that follow a model-based quantity takeoff procedure. BIM employs a model-based takeoff procedure to create more accurate quantity takeoffs.
BIM makes an effective planning process by using accurate visual and specification data from the project.
The cost of construction materials keeps on fluctuating. Therefore, a quantity takeoff that does not consider unexpected costs of construction materials accurately would affect the profit and schedule of the undertaking.
By determining the factors, area, and the time when costs increase, the substance cost can be estimated for the worst-case scenario. This would help to achieve more precise quantity takeoffs.
With the increase in the scope of the project, the number of takeoffs also increases. This condition demands every individual to manage the whole procedure.
Workflow can be efficiently optimized using cloud-based instruments to manage the takeoffs.
The use of cloud-based takeoff technology saves and edits the information in real-time. Cloud-based technology saves the time lost for conducting meetings and errors caused due to miscommunication.
These items are common for all takeoffs whose omission can lead to undertaking overruns. A master checklist includes all the potential items included in a usual takeoff. In addition, a master checklist can be updated regularly to account for items missed before. So a master checklist can be used as one-piece advice for any estimator.
Quantity takeoffs can be integrated with the cost estimation process using certain takeoff software. The integration of takeoff software into the estimating program helps to quickly implement material cost adjustments and other changes in the estimate. This process saves time and labor.
Quantity takeoffs are necessary to analyze the overall undertaking scope and undertaking budget. Using the right takeoff strategies and technologies, as mentioned above, are the top ways to enhance the quantity take process.
