At this point, it may be helpful to sketch a functional block layout. I recommend taking your preliminary plan around your plant for input. If your key people don't agree with the design, the project could easily fail. Some important components of our plant's layout came from new hourly employees who had worked elsewhere. Scouting an Existing Building Armed with your size requirements, try very, very hard to find an existing building.
New ones are expensive and a pain to build.
We spent a long time reviewing numerous options at existing buildings. Unfortunately, we could not find a facility that had the space we needed in a decent area. If you're relocating, consider where your employees live. If their commute increases significantly, you'll probably lose people. Consider the viability of the neighborhood.
