SCENARIO: Carla, an estimator at Genco Power is developing an estimate for upcoming maintenance work at one of Genco’s power plants. She wants to explore two different options for removing and replacing a feed water system.
In one approach, she assumes that crews will be able to increase access to the work area by cutting a large access way through the wall of the metal building. This would allow for easier access to the feed water system that needs replacing. Parts and materials could be staged nearby outdoors and hoisted into position as they’re needed. Also, crews would be able to access the work area more readily, streamlining operations.
She also uses another approach, in which Engineering won’t approve plans for increased access by cutting through the building’s wall. In this case, the replacement of the feed water system will be more tedious, as workers will need to wind their way through existing plant infrastructure to access the area in which they will be working. This has a pronounced effect on the crews’ productivity and their ability to transport and stage materials to the area where the work will be performed.
Create cost items for both options and use the Suspend feature to toggle between them.
Use the Snapshot feature to create a second version of the estimate with the second option estimated. You can compare the original estimate to the snapshot copy of the estimate containing the alternate option.
Create the second option in the same estimate and assign different alternate scenario records to each option respectively. Control whether the pay item is included using the Alternate Scenario drop-down.

Create cost items for both options and use the Suspend feature to toggle between them.
Suspending cost items removes it from the estimate effectively, but this process is more cumbersome, since you have to suspend each item manually and re- price each time.
Use the Snapshot feature to create a second version of the estimate with the second option estimated. You can compare the original estimate to the snapshot copy of the estimate containing the alternate option.
This gives you nice visibility of the two versions of the estimate side by side but is a bit laborious to develop and manage.
Create the second option in the same estimate and assign different alternate scenario records to each option respectively. Control whether the pay item is included using the Alternate Scenario drop-down.
This is the most efficient approach. The Alternate Scenarios drop-down makes it easy to select and de-select alternates, with a few clicks.
