Duo Construction Estimators: Your Trusted Cost Estimators

Construction cost estimation is a process that predicts the actual costs of a building project. A cost estimate is calculated using the inputs of labour rates, material costs, and task duration. It provides a financial baseline for a project, which is used to bid on contracts, budget resources, and control costs.

Accurate construction cost estimation is an essential step for the success of any construction project. It helps in:

• Budgeting: A cost estimate facilitates budgeting and securing funding for the project.
• Decision making: It aids in making informed decisions regarding project feasibility and execution.
• Risk management: It helps identify potential financial risks and develop mitigation strategies.

Duo Tax offers a comprehensive suite of construction cost estimating services. Our team is experienced in providing detailed and accurate cost estimates for various building projects.

You need a clear estimate of expected construction costs before committing to plans, contracts, or finance, so you can budget accurately and avoid cost blowouts.

Duo Tax can prepare a Preliminary Cost Report to give you an early high-level construction estimate for budgeting and tax planning. This helps you understand likely costs upfront and make confident decisions before detailed costing begins.

You need to test whether the build cost aligns with your expected outcome, such as profit, resale value, or overall feasibility, before construction starts.

Duo Tax can provide an Initial Cost Report with a detailed breakdown of projected construction costs before work begins. This gives you clearer feasibility insights, supports better decision-making, and helps you adjust scope early if needed.

You need an itemised cost breakdown to support tendering and ensure contractors quote on the same scope, reducing gaps, variations, and disputes later.

Duo Tax can produce a Bill of Quantities that details materials, labour, and costs in a clear, itemised format. This supports more accurate tender pricing, makes quotes easier to compare, and helps keep the project on budget from the start.

You need to confirm the work completed matches what is being claimed, especially when payments are being released in stages through a lender or funding arrangement.

Duo Tax can prepare a Progress Claim Construction Report to verify claimed construction progress before funds are released. This helps reduce the risk of overpayment, supports smoother cash flow, and keeps the build financially controlled throughout the project.

You need a clear cost plan that shows where the budget is allocated, so lenders or investors can assess risk and funding requirements with confidence.

Duo Tax can provide an Elemental Cost Plan that breaks total construction costs into key elements for detailed budgeting. This improves transparency for lenders and investors, supports funding discussions, and helps strengthen project approvals.

Construction Cost Estimation is the process of calculating the expected cost of a construction project, based on the scope of works, materials, labour, and site requirements.

You may need a Construction Cost Estimation report to plan your budget, confirm feasibility, support funding applications, compare quotes, or manage costs during construction.

Duo Tax offers a range of Construction Cost Estimation reports, including a Preliminary Cost Report, Initial Cost Report, Bill of Quantities, Progress Claim Construction Report, and Elemental Cost Plan.

The right report depends on your stage of build and what you need the estimate for, such as early budgeting, tendering, finance approval, or validating progress claims.

Yes. A Construction Cost Estimation report helps identify expected costs early, so you can plan accurately and reduce the risk of unexpected expenses during the project.

Yes. Many lenders require cost documentation to support construction funding, and a Construction Cost Estimation report can provide the clarity they need.

Typically, you’ll need building plans or drawings, project details, site location, scope of works, and any relevant documentation that impacts costs.

No. Construction Cost Estimation is also useful during the build, especially for reviewing progress claims, monitoring costs, and managing variations.

Accuracy depends on the level of detail provided and the project stage. Estimates become more accurate as plans and inclusions are finalised.
