The ease of use, functionality for both our clients as well as partners is great! It's easy enough to navigate through all aspects with no training required at least initially within my experience (we've had some initial trainings but that was it).
I can't think about any downsides yet; however if there are issues please let me know so we address them ASAP :) We're using this software across almost every project/phase currently including design-build phases which allows us to measure progress more efficiently than ever before without having additional staff resources dedicated solely towards measuring purposes - also reduces risk by being able to track projects faster thus mitigating potential delays or other risks associated wtih submittals not meeting deadlines etc.. As an owner / principal designer building new structures i'm now better informed when making decisions regarding measurements during construction phase vs preconstruction planning.
