Also, we just released a new version of PlusSPec called PlusDesignBuild, you probably guessed it from the name, it is for Design-Build firms and there is a big focus on Advanced estimating and Quantity Takeoffs for Builders and tradespeople yet there is also a lot functionality for Design Firms and Architects.
