Project estimation refers to forecasting the costs, resources, and time required to complete a project. It is critical to project planning and financial management in contracting, serving as the basis for calculating expected costs and profit when submitting a proposal. Estimates can be created directly from the project or by going to Project Costing Project Costing Documents Project Estimates.

This process includes:

To manage estimates in the system:

Project Estimation Method

The calculation method for project estimates is set in Administration → Project Costing → Default Method of Project Estimate Calculation.

There are two budgeting methods:

  1. Independent Calculation of Costs and Revenues

In this method, revenue and cost estimates are entered separately and independently. Revenue figures are manually set and do not depend on cost data. This approach is typically used when revenue is fixed or predetermined, such as in fixed-price contracts, while costs are estimated separately for budgeting and tracking purposes.

       2. Calculation of Revenues Based on Costs

Revenue is automatically calculated by applying a markup percentage to the estimated costs. Costs such as labor, materials, and overhead are entered first, and revenue is derived based on these figures plus the markup. This method is ideal when pricing is closely tied to the actual or expected cost structure and when profitability depends on managing costs effectively.

If time-based planning is enabled, the Estimates by Period tab appears. It splits revenue, cost, and overhead estimates across specific planning periods to help track the budget over time.

Ways to Create Project Estimates

There are two main ways to create a project estimate:

a) From within the project
Open the relevant Project → Click Create/Edit Current Estimate or use Generate → Project Estimate to create an estimate based on the project data.

b) From the document list
Go to Project Costing → Project Costing Documents → Project Estimates → Click Create to start a new estimation document.

Creating a Project Estimate document. The Main tab

On this tab, you can enter general information about the project's estimate: the project, customer, project type, entity, and the employee who is responsible for the project. Also, you can specify whether you need to split estimates by planning period.

Depending on the selected method of estimate calculation, the form has different tabs:

If for any method, the Estimates by Period check box is selected, one more tab, Estimates by Period, appears. 

Creating a Project Estimate document. The Revenue and Costs tab

This tab is used to build the project budget using the Calculation of Revenue Based on Costs method. It includes two main sections:

  1. Revenues (upper pane)
  2. Costs (lower pane)

Both panes work together to calculate the total project cost and the resulting markup and revenue.

Revenues Pane (Upper Pane)

This pane is used to define revenue items (BOQ lines) for the project. Each revenue line can be linked to one or more cost lines in the Costs pane.


Costs Pane (Lower Pane)

This section is used to add and manage the costs associated with the selected revenue item.

To add a new cost, click Add with the relevant revenue line selected.

Creating a Project Estimate document. The Overheads tab

This tab is used to enter the estimates of overhead costs for the project. This tab is available if the estimation method is Independent Calculation of Costs and Revenues.

To allocate the overhead costs, use the Allocate Overhead Costs button on the toolbar of the Revenues and Costs tab.

Click Add to include a new overhead cost for the project, or you can input overhead costs by project tasks.

Choose an Expense Item to classify the overhead cost (e.g., Overheads).

Select the Cost Element, Quantity, and UOM (optional fields).

Enter the Price of the overhead cost.

The VAT, % column automatically displays the VAT percentage for the overhead cost, but you can adjust it if necessary.

The Amount Excl. VAT column shows the total cost of the overhead excluding VAT, and this amount will be included in the project estimates.
