I only know RSMeans from the analog days when they had books. I found their data very lacking and obviously not taking into account actual installation cost. For example, when we replace a boiler, the required piping and equipment around it and labor can cost as much as what the boiler cost, or it can cost 3 times as much. That is a difference between 100% or 200% project cost. Our projects are smaller, so they may have less data for that.
I also question how RS Means actually get their data. When we bid out projects, we get calls from such companies asking questions about cost. The person asking usually has zero knowledge about construction and seems to only fill a checklist. They also never seem to have the plans. I doubt whatever I tell them at that point makes them understand what our project actually includes.
I'm curious to know how to leverage Revit better. But I think it only will be a schematic estimate. Like if you demolish 200ft² of ceiling, you could assign a $-amount to each ft². the problem is, site conditions can change that $-amount a lot. And if you demo twice the amount, your cost per ft² will (hopefully) decrease. Si if you originally say you demo 200 ft² of ceiling and decide it is $2 per ft², and then the project scope changes to demo 4,000 ft², you will end up with a too large demo estimate assuming with that much demo each ft² will be much easier to do.
