A construction takeoff project is estimating quantities of materials, labor, and equipment to complete a construction project. This typically involves accurately measuring the area’s dimensions for a building or structure, including any variations in grade, slope, or elevation. It also considers the material used in the construction and the various elements that must be installed within the space.
While this process may seem cut and dry, a few different types of takeoffs can be done depending on the scope of the construction project, each with its own unique set of considerations.
The Value of Construction Takeoffs
Construction takeoffs directly impact the success of the larger project. By accurately measuring materials, labor, and equipment needed for a particular space, construction takeoffs reduce costs while ensuring all necessary components are accounted for before beginning the project. This helps avoid any costly delays and surprises during the construction process.
Additionally, construction takeoffs allow contractors to provide competitive bids by providing these estimations ahead of time.
Other benefits include:
- Improved accuracy in budgeting;
- Enhanced risk management;
- Increased project planning efficiency;
- Reduced errors and rework costs.
Due to its importance in avoiding costly, many industry professionals suggest that it’s easier and less expensive to do a construction takeoff correctly at the outset than fixing mistakes later on in the project.
Further, those who invest sufficient time and energy into getting their construction takeoff right typically experience much better cost savings and overall satisfaction with the completed project.
Standard Steps for a Construction Takeoff
To complete a construction takeoff, it is important to understand the following standard steps:
- Identify construction procurement methods and contract types: Common contract types include fixed price contracts, cost-plus contracts, unit price contracts, and design/build contracts.
- Source the appropriate software: The use of construction takeoff software has become increasingly common, and it can help improve accuracy by automating calculations and visualizing the project. It also allows for a more efficient exchange of information between stakeholders.
- Outline general conditions vs. general requirements: Before starting the takeoff process, document any general conditions (i.e., safety requirements) that must be met and any specific requirements (i.e., specifications of materials or labor rates).
- Gather project documents: All relevant documents should be gathered before initiating the takeoff process to ensure accuracy within calculations, such as measurements, materials needed, etc.
- Compile calculations and estimate costs: This involves taking accurate measurements within a space and calculating materials needed for a particular job and any associated costs — both labor and equipment — required for completion.
- Finalize takeoff and submit bid: Once all calculations have been completed and reviewed, your final construction takeoff can be submitted with a bid to the client.
It's also wise to periodically review takeoffs to ensure accuracy and take appropriate action if necessary.
In addition to the standard takeoff steps discussed above, other factors should be considered to ensure the successful completion of any construction project. These include:
- Time management: Construction takeoffs require a significant amount of time, so plan accordingly to deliver on time and within budget.
- Scope and budget alignment: Understand the scope of work requested by the client and their overall budget. This will help you make sure all takeoffs take these constraints into account.
- Safety requirements: All safety requirements must be met when completing takeoffs since this will impact labor costs and materials.
- Quality control: Construction takeoffs provide an opportunity to make sure all materials used are up to the required standard.
By following these guidelines, construction professionals can ensure their takeoffs are accurate, efficient, and profitable.
Who Is Responsible for a Construction Takeoff?
The responsibility for construction takeoff is typically divided among various construction professionals, including:
- Quantity surveyors perform the calculations needed to measure the materials, labor, and equipment required for a given space. They’re often aided by cloud-based quantity estimation software, which can make calculation and documentation easier.
- Cost estimators are responsible for assessing any potential costs associated with the project, such as overhead fees or extra charges. Estimation software designed explicitly for surveyors can help streamline this process.
- Contractors are ultimately responsible for ensuring that all components of the project meet the original specifications outlined in the contract and come in at or under budget. There are several AI-based reporting tools and software options specifically developed to assist contractors.
With the help of automated construction takeoff software and strong communication, completing a construction takeoff can be efficient and profitable.
Quantity Takeoff vs. Material Takeoff
Quantity and material takeoffs are two separate but related processes used in construction that are necessary to estimate the costs associated with a particular project accurately.
