"Buy In" like invest in it? Or "Buy In" like subscribe? I have been out of commercial construction for 4 years now so maybe things have changed but when I was in estimating, it was all we used.
I used it in DFW for 3 years at a GC. From a GC standpoint, the opportunities were not the good part, the network of subcontractors was. It made it easy to satisfy MWBE and HUB requirements and find the occasional good sub you hadn't been aware of before. It would definitely be worth it just from that alone. Now if you are a subcontractor, I would think that 1,800 a year would be well worth it even if you just got a few phone calls a year that you wouldn't have before. You will see tons of jobs from GC's that simply see where you are located and what you do, also you can download the plans from there. PM me if you want to go into more details about and I would be glad to walk you through it.
