Understanding Model Estimating
Note: You require a license to use Sage Estimating Models.
Model Estimating streamlines the estimating process by providing most of the details needed during takeoff. Because each model includes a complete set of items and assemblies for a structural element, you can take off everything for that element at once. In addition, the model may even include the logic to feed the proper values into its items and assemblies.
During takeoff, input can come from questions, such as 'What is the height of each story?' and 'Is an alarm system required?' Or the input can simply come from existing variables that are part of each item and assembly. You have control over whether those variables appear (for input purposes) or are hidden (with default values which act as assumptions).
The resulting estimate contains all the details (costs, crews, hours, waste factors, and so on) generated from the assemblies and items that make up the model. And because this is an Estimating spreadsheet, you have the power to make changes to the estimate after takeoff.
By using models for takeoff, you gain the ability to:
- Group multiple items and assemblies as a single object
- Set up common, global variables for items and assemblies
- Ask questions to obtain dimensions and specifications
- Pre-load the location, WBS values, and productivity adjustment for items and assemblies
- Take off multiple occurrences of items and assemblies within a model
- Take off multiple passes of items and assemblies within a model
