Material Takeoff vs Quantity Surveying: Key Differences Every Estimator Should Know
MSB ESTIMATING LLC
In the world of estimating construction, the word material takeoff (MTO) and quantity survey (QS) are often used - but they are not the same. While both play an important role in cost estimate and project plan, they vary in scope, expansion, responsibility and purpose.
If you are an in -estimate, contractor, project manager, or even a student in construction management, understanding the difference between these two can help you improve accuracy, streamline workflows and ensure better cost control.
What is the material takeoff (MTO)?
Material takeoff is the process of determining all physical materials required to create a structure based on architectural and engineering images. This is usually one of the first stages in preparing cost estimate. material takeoff
Main features of MTO:
Only focuses on materials Provides volume, type and units Except for labor, equipment and overhead costs Often done by estimates or engineers Feed directly in purchase and purchase Example: If you are building a wall, then MTO includes: 1,200 bricks 10 bags of mortar 5 ribar rods 2 gallons of waterproof coating But this does not include labor to install them or establish the implications of cost - which comes later. material takeoffWhat is the volume survey (QS)?
Quantity Survey is a broad, more strategic discipline focused on overall financial and contractual management of a construction project. It includes the material takeoff, but also spreads beyond.
Major responsibilities of a volume surveyor:
Preparing detailed cost estimate (material, labor, plant)
Tender and bidding analysis
Cost scheme and budget
value engineering
Contract administration
Change order management
Post -contract cost control and final account preparation
Example:
Using the same wall example, a volume will be the surveyor:
Estimate Total Cost (Material + Labor + Plant)
Prepare the volume bill (BOQ)
Compare quotes from subcontinent
Monitor cost variation during construction
Ensure that the project stays within the budget material takeoff
🆚 MTO vs QS: A side-by-side comparison
Feature content takeoff (MTO) volume survey (QS) Focus material only full project cost and contract management Scope narrow and effort-specific widespread and strategic Responsibility estimate, engineer volume surveyor, cost advisor Output material list or schedule boqs, estimates, evaluation Tools use takeoff software (eg blueem, stack) cost management system (eg costx, candy, humble) Pre-construction pre-construction and post-building Final Use Purchase and Budget Project Cost Control, Reporting, Customer BillingWhen use MTO vs Volume Survey
When use the content takeoff:
Prepare a quick estimate for the material
Purchase teams require order quantity
Specific trades (eg drywall, steel, concrete)
Use volume survey when:
Prepares a detailed budget
Effects on large or complex projects
Management of contract, diversity or customer payment
Running cost control and reporting require
