1. Introduction
Cost estimation is the process of estimating the amount of money and other resources required to finish a project within a specific time frame. Cost estimation generates a total sum that establishes a project's budget by taking into account all project-related requirements, including labor and supplies. An early cost estimate can help an organization decide whether to approve a project, and if the project proceeds, it can help define its scope. A company may decide to scale back the project to match what they can afford if the cost estimation is too high (it is also required to begin securing funding for the project). The cost estimate is used to control all associated costs once the project is underway in order to keep it under budget. Should the cost estimation be over the budget, the owner’s specifications must be altered in accordance with the target budget.
2. Objective
This report aims to calculate detailed estimation for a prospective two-story building to be constructed in Toronto. For its cost estimation to report to the owners, we have considered these steps:
✓ Quantity Take-off (QTO)
✓ Pricing
✓ Master Format conversion
✓ Detailed estimation
3.
Project Description
A two-story residential building to be constructed in Toronto, Ontario in 2023 with a Gross Floor Area of roughly 5,500 Square Feet is a significant undertaking that requires careful planning and attention to detail. The preliminary design, which includes a basement, a ground floor, and a second floor, suggests that the building will have ample space for living, entertaining, and storage. The conceptual structural framework is envisioned as being made of steel. Steel's high strength-to-weight ratio and versatility make it an ideal material for use in conceptual structural frameworks. It can support heavy loads without adding unnecessary weight to the structure, and it can be easily fabricated into various shapes and sizes to suit the needs of a particular design. Steel is also resistant to fire and pests, making it a
safe choice for buildings that require high levels of protection. Moreover, steel is an environmentally friendly material, as it can be recycled and repurposed after its initial use, reducing waste and minimizing the environmental impact of construction projects.
The exterior finishes for the building will be covered by masonry bricks. Masonry is a durable and long-lasting building material, that provides great insulation and fire resistance. It also adds an aesthetic appeal to the building, creating a classic and timeless look. Masonry bricks come in a wide range of varieties, each with its own unique characteristics, colors, and textures. The choice of masonry brick will depend on the design aesthetic, budget, and other factors.
4. Detailed Estimation
In order to do the detailed estimation, the following steps should be undertaken:
• Work Breakdown Structure (WBS) use (Uni Format approach)
• Quantity Take-Off (QTO)
• Pricing
4.1.
Work Breakdown Structure (WBS)
Utilizing the work breakdown structure (WBS), which is a project management tool, helps large projects to be completed step-by-step. The WBS allows integrating the scope, cost, and deliverables into a single tool by dividing the project into smaller components. Albeit most WBSs are deliverable-based (Master Format), they can also be phase-based (Uni Format).

Z2030 Construction Contingency
The Quantity Take-Off process is crucial in construction cost estimation, involving the measurement of labor, materials, and resources from project drawings. This data is then used to prepare a detailed cost estimate, providing a comprehensive overview of total project expenses.
4.3.
Pricing
Pricing in construction cost estimation is a critical process that involves calculating all costs associated with a project, including materials, labor, equipment, and other expenses. By breaking the project into components such as excavation, foundation, framing, roofing, electrical, plumbing, and finishing work we can estimate costs more accurately. Utilizing RSMeans provides a comprehensive list of unit prices that account for overhead and profit. Factors like project location, design complexity, and material quality significantly influence these estimates. This approach ensures a comprehensive budget, covering both direct and indirect costs, and helps manage expenses effectively, facilitating timely completion of the project within budget constraints.
Excavation (Cut)

For this section, the sequence of activities was first converted from Uni Format to Master Format, which resulted in a list of activities with their corresponding Master Format code. These activities were then categorized into 5 different categories, which correspond to various phases or aspects of the project.
To calculate the project's cost, we used a one-month trial version of RSMeans. However, the trial version only provided access to the Master Format 2018 and cost data from 2011. Therefore, the cost data from 2011 had to be converted to 2023 to fathom how much it would cost were it to be built in 2023.
Hence, the complete cost estimation for constructing this project in 2023 is just over 1.26 million Canadian Dollars.
8. Conclusion
He estimated project cost in 2011 was $805,000. Adjusted for inflation using the Historical Cost Index from RS Means, the 2023 estimate rises to approximately $1.26 million. This figure is about 13.5% higher than the midterm report's conceptual and elemental cost estimates of $1.09 million and $1.11 million.
