A contractor should do all of the following when estimating a project EXCEPT?

When estimating a project, it is crucial for a contractor to avoid assuming ideal conditions. Estimating based on ideal circumstances can lead to inaccurate projections of time, cost, and resource allocation. Real-world conditions are often unpredictable, and factors such as adverse weather, labor availability, and site-specific challenges can significantly affect project outcomes.

By considering weather patterns, accounting for material costs, and analyzing previous projects, a contractor can create a more realistic and informed estimate that reflects potential challenges and variations in the construction process. These practices help ensure that once a project begins, there are fewer surprises regarding costs and scheduling. Therefore, assuming ideal conditions is not a reliable practice in the estimating process and is not advisable for successful project management.
