How are construction estimates calculated in Level 5?
All estimates are calculated by assumptions and can be susceptible to change when costs are updated. Bid estimates meet the criteria defined in the Level 5 Definitive Estimate in terms of accuracy. The bid combines construction documents, take-offs, and direct costs.
What are the steps in a cost estimate?
The U.S. government has identified a 12-step process that results in reliable and valid cost estimates. Those twelve steps are outlined below. Define Estimate’s Purpose: Determine the purpose of the estimate, the level of detail which is required, who receives the estimate and the overall scope of the estimate.
When do you have to re-estimate the cost of a project?
In subsequent phases, costs are typically (re-)estimated if relevant new information and details become known or if changes to the project scope or timeline occur. One of the common reasons for re-estimating cost is, for instance, when the indicators of the project controlling suggest that the original budget baseline cannot be met.
Why are estimated costs higher at the beginning of a project?
The estimated costs during the earlier stages of a project have less accuracy, and those expected later have higher certainty. The ranges will be higher at the beginning of the project and will narrow down as the project advances. Project cost estimates are characterized by how precisely defined the scope is at the time of estimation.

How does the estimator calculate the total cost of a project?
The estimator or project manager calculates the total costs of the project and level of funding and budget allocations necessary for completion. This calculation leads to creating the budget. The project manager estimates the total cost by using the estimate and includes risk management activities along with reserves (contingency and management).
How to come up with a cost estimate?
Define Estimate’s Purpose: Determine the purpose of the estimate, the level of detail which is required, who receives the estimate and the overall scope of the estimate. Develop Estimating Plan: Assemble a cost-estimating team, and outline their approach. Develop a timeline, and determine who will do the independent cost estimate.
How is a substantive estimate of a project created?
The substantive estimate is based on estimated unit costs. The estimate is created by analyzing reasonably finalized project designs, objectives, and deliverables that are established by the company. Additionally, it used to control project expenditures to stay within the budget.
