What Should Be Included in a Material Takeoff Report?
A Material Takeoff (MTO) report is a vital document in construction cost estimating. It provides a detailed list of all the materials required to complete a project, including their quantities, units of measurement, and sometimes specifications. A well-prepared MTO ensures accurate budgeting, efficient procurement, and effective project planning.
Whether you’re a Quantity Surveyor, estimator, or contractor, understanding what to include in a material takeoff report is key to avoiding cost overruns, delays, and waste.
What is a Material Takeoff Report?
A Material Takeoff Report is a document that breaks down all the raw materials needed for a construction project, derived directly from the architectural, structural, mechanical, and electrical drawings. It serves as a foundation for cost estimation, procurement, and project scheduling.
Key Elements to Include in a Material Takeoff Report
1. Item Number or Code
Each material should be assigned a unique identifier or item number, especially in larger projects. This helps with:
• Easy tracking in procurement systems.
• Cross-referencing with specifications and drawings.
2. Material Description
Clearly describe each material item to avoid confusion or misinterpretation. The description should include:
• Type of material (e.g. C30 concrete, 100mm dense blocks).
• Size and grade (e.g. 10mm rebar, 18mm plywood).
• Finish or treatment, if applicable (e.g. galvanised steel, treated timber).
A detailed description ensures suppliers and site teams know exactly what is required.
3. Unit of Measurement (UOM)
Define how the material quantity is measured. Common units include:
• Cubic metres (m³) for concrete, excavation.
• Square metres (m²) for plastering, roofing, tiling.
• Linear metres (m) for pipes, cables, skirting boards.
• Tonnes or kilograms (kg) for steel reinforcement.
• Number or pieces (No.) for doors, fittings, fixtures.
Using standard measurement units in line with SMM7 or NRM2 guidelines ensures consistency.
4. Quantity Required
This is the measured quantity of each material needed to complete the work. It should be based on:
• Scaled drawings or BIM models.
• Project specifications.
• Adjusted for wastage factors, where necessary.
Accurate quantities help avoid material shortages or over-ordering.
5. Wastage Allowance (if applicable)
Some materials require a wastage allowance to account for offcuts, breakages, or installation loss. Typical allowances include:
• 5–10% for tiles and bricks.
• 10–15% for plasterboard and insulation.
• 2–5% for reinforcement steel.
Including this in the report helps plan realistic procurement quantities.
6. Total Quantity (Including Wastage)
After applying the wastage factor, the total quantity is calculated. This figure should be used for:
• Material ordering.
• Cost estimating and budgeting.
7. Reference Drawing or Section
Indicate the drawing number or section from which the quantity was taken. This is useful for:
• Verification during reviews.
• Cross-checking with design changes.
• Quality assurance and audit trails.
8. Comments or Notes
Add any relevant notes that provide context or clarify assumptions, such as:
• “To be installed externally – requires weatherproof finish.”
• “Provisional quantity – to be confirmed after site survey.”
• “Quantity includes allowance for service void.”
This helps all stakeholders understand the reasoning behind each entry.
Optional (But Helpful) Inclusions
9. Unit Rate or Cost (Optional)
While not always required in a basic MTO, including unit rates or cost estimates can help:
• Prepare preliminary budgets.
• Track cost implications of design changes.
• Align with supplier pricing during procurement.
10. Supplier or Specification Reference
If materials are specified by a particular brand or supplier, this can be noted in the report to ensure consistency.
Example:
• Insulation board: Kingspan Kooltherm K5, 50mm.
• Paint: Dulux Trade Diamond Matt, white.
11. Delivery Location or Phase
On larger or phased projects, it may be useful to include:
• Which zone or phase the materials are needed for.
• Expected delivery date or time period.
This assists with logistics planning and on-site coordination.
Typical Format Example (Narrative Style)
• Item No.: 001
• Description: C30/37 ready-mix concrete for ground floor slab.
• Unit: Cubic metre (m³)
• Quantity: 45.00 m³
• Wastage Allowance: 5%
• Total Quantity (Inc. Wastage): 47.25 m³
• Drawing Reference: S-101 Rev A
• Notes: Includes thickenings around column bases.
Frequently Asked Questions
Is a material takeoff the same as a Bill of Quantities (BoQ)?
No. A material takeoff focuses purely on raw materials, while a BoQ includes detailed descriptions of work items, quantities, units, and pricing for tendering and contract purposes.
Should waste be included in a material takeoff?
Yes. Including a realistic wastage allowance ensures that materials are not under-ordered and helps avoid project delays.
Who prepares the material takeoff?
Typically, a Quantity Surveyor, estimator, or takeoff technician prepares the MTO based on project drawings or BIM models.
Can software generate a material takeoff?
Yes. Tools like CostX, Bluebeam Revu, PlanSwift, and Revit can generate takeoffs automatically from digital drawings or models, saving time and improving accuracy.
How often should the material takeoff be updated?
Any time the design changes, the MTO should be reviewed and updated to reflect the new requirements.
Conclusion
A well-structured Material Takeoff Report is critical for accurate cost estimation, procurement, and project planning. It provides clear, detailed, and measurable information that guides Quantity Surveyors, contractors, and suppliers throughout the construction lifecycle.
By including the right information – from material descriptions and units to drawing references and wastage allowances – the MTO becomes a reliable foundation for financial control and site execution.
As construction continues to evolve with digital tools and BIM integration, the importance of precise, transparent material takeoffs is greater than ever.
