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

• A. Assume ideal conditions.
• B. Review project constraints.
• C. Consult with subcontractors.
• D. Identify risks.

Answer: (A)

Estimating a project starts with building a realistic plan by considering what could affect cost and schedule. You must review project constraints such as budget, timeline, site access, permits, and environmental factors; consult with subcontractors to obtain current prices and lead times for trades; and identify potential risks to set aside appropriate contingencies. You should not assume ideal conditions because real jobs involve delays, imperfect site conditions, weather, material shortages, and unforeseen issues. Relying on ideal conditions tends to produce optimistic estimates that underrepresent true costs and schedules, leading to overruns. By accounting for constraints, gathering input from subs, and assessing risks, the estimate reflects likely outcomes and provides a sensible contingency.
