Como Fazer o Estudo de Viabilidade de Obras?

Summary

In this video, Gustavo Martins from the blog 'Engenheiro de Custos' discusses the importance and process of conducting a viability study for construction projects. He explains various methods for estimating costs, including parametric budgeting, using tools like Cube or past project data, and how BIM can help refine estimates. He also touches on the value of historical data and technology in streamlining the process. The video emphasizes the significance of feasibility studies in determining project viability, securing funding, and ultimately ensuring profitable results for construction ventures.

Takeaways

• 😀 The viability study of a construction project helps determine its feasibility, costs, and whether the project should proceed.
• 😀 The study is important for understanding project costs, ensuring profitability, and deciding whether to move forward with the construction or abandon it.
• 😀 Budgeting for a project should use various parameters such as past projects, regional costs, and specific metrics like the Cub (Construction Cost Unit).
• 😀 A parameter-based approach involves using construction cost indexes, either from tools like Cub or from previous projects in the same region and type of work.
• 😀 It's important to consider factors like foundation and other structural components that might not be included in standard cost estimations like Cub.
• 😀 Using BIM (Building Information Modeling) technology can assist in generating more accurate cost estimates even if all the project's designs are not yet finalized.
• 😀 Preliminary budgets can be based on rough estimates, using metrics such as concrete volume or the cost per square meter for various construction materials.
• 😀 Comparing the results from multiple cost estimation methods (e.g., Cub vs. preliminary budget) can provide a more accurate feasibility analysis.
• 😀 Historical data from previous projects is valuable for comparison, helping estimate costs and identify trends or variances that can affect new projects.
• 😀 Technology, such as ERP software, can automate data collection and analysis, streamlining cost estimation and project management.
• 😀 A viability study is crucial early in a project, especially when full designs aren't available, and can guide decisions about financing and project execution.
• 😀 The goal of a viability study is to ensure a project is financially feasible, enabling profitable construction and enabling future scalability and growth.

Q & A

What is the purpose of conducting a feasibility study for a construction project?

The purpose of conducting a feasibility study is to assess whether a construction project is viable. This includes determining the potential costs, whether the project is financially viable, and whether it should proceed or be abandoned based on expected outcomes.

What role does parametric budgeting play in a feasibility study?

Parametric budgeting in a feasibility study involves using parameters, such as cost per square meter, historical project data, or industry standards, to estimate the potential cost of a construction project. This helps to get an initial estimate without having full project details.

Can you rely solely on Cub (Custo Unitário Básico) data for budgeting in a feasibility study?

No, you should not rely solely on Cub data, as it may not account for all the specific details of your project, such as foundation work or other unique factors. Cub data provides a base cost per square meter, but additional parameters must be considered for accurate budgeting.

How can historical data from previous projects be useful in a feasibility study?

Historical data from previous projects can provide valuable insights into costs and trends specific to your region and type of construction. It allows for more tailored estimates based on past performance, helping to refine cost predictions.

What is the difference between a parametric budget and a preliminary budget?

A parametric budget uses general industry data, like cost per square meter or material quantities, for estimation. A preliminary budget, on the other hand, provides a more detailed breakdown, taking into account specific project characteristics, like structural design, materials, and labor costs.

Why is it important to consider different parameters, such as steel or formwork rates, in a preliminary budget?

Considering parameters like steel rates and formwork helps to refine the budget, providing more accurate cost estimations. These parameters account for the quantities of materials required and the complexity of certain tasks, giving a clearer picture of the project's total cost.

How does BIM (Building Information Modeling) contribute to a feasibility study?

BIM allows for the integration of detailed project specifications and data into the feasibility study. It helps in visualizing the project, estimating material quantities, and determining costs more accurately, even if some design elements are not yet finalized.

What is the significance of using software tools for cost control in construction projects?

Using software tools for cost control simplifies data management, streamlines the estimation process, and provides real-time insights into project costs. These tools help monitor budgets, track expenditures, and generate reports for more informed decision-making.

How does a feasibility study help in securing financing for a construction project?

A feasibility study provides a clear understanding of the project's costs, risks, and potential returns, which is crucial when seeking financing from banks or investors. It demonstrates that the project is viable and can be completed within budget, making it more attractive for lenders.

When should the feasibility study be conducted during the project lifecycle?

The feasibility study should be conducted early in the project lifecycle, often before detailed design work begins. This ensures that all key financial and operational considerations are addressed before committing to a full-scale project.
