The bottom-up estimating approach is characterized as detailed and very time-consuming because it involves a thorough breakdown of the project into smaller, manageable components or tasks. Each component is estimated individually regarding resources, time, and costs, which then aggregate to form a comprehensive estimate for the entire project.

This method allows for greater accuracy since it considers the specifics of each task, capturing variations in labor, materials, overhead, and potential risks. However, the trade-off for this level of detail is the considerable time and effort required to gather and analyze data for all elements of the project. Because of its rigorous nature, bottom-up estimating is particularly useful for complex projects where precise budgeting is critical.

In contrast, other estimating methods like top-down estimating, analogous estimating, and parametric estimating typically involve less detail and can be completed more quickly, making bottom-up estimating distinctively time-consuming and thorough.
