So (please prove me wrong), all estimating software is fundamentally built around 3 core features: 1. Take-off tools. Every business needs one of these, the two main ones are planswift and Bluebeam. I love Bluebeam but a lot of people hate it. Its just he one I'm used to 2. Managing cost/productivity/quantity databases- ie storing labor, plant, material, subcontractor rates 3. Preparing prices - combining quantities with rates etc. For most contractors, all you need is a quantity take off tool and excel. There are trade specific tools, but they often just have more data and are tailored towards trade specific workflows And AI just adds intelligence to this process. Ie can convert bid documents into requirements, or automatically extract quantities from drawings I did a breakdown in this video. If you like + comment it helps the algorithm!
