Co-construct uses a broad definition of the term “selection.” For example, you may want to know if a wall between the kitchen and great room should be a half or full wall. Simply make this a selection item. It may not be cost-impacting or change order-worthy, but it will keep all your decisions, selections, option upgrades, etc… all in one place. Plus, by creating a selection item for this, if there is any future dialog about the wall, you and your clients can easily add comments to that selection item.
If there are no cost implications of a decision, give it a price of $0. Co-construct will track the decision and communication about it, but it will not affect the project’s price.
