Water is piggy backed from my home. Cost in 1991 dollars $40K. High pressure sodium lights 400 watts $800 used, interior walls are steel roof decking 22 gage approx. $900. Plus a lot of other incidentals and toys.
One of your questions concerned hanging shelves and or any thing from the interior walls of a steel build. The roof decking could not have been a better fit for my interior walls. I put down another base angle and the roof decking is screwed between the middle girt and the new bottom base angle, they are 8' and 9' high respectively. I painted it bright white when initially installed but 24 years later it is starting to show it's age. I have done a lot of arcing and sparking inside my building. I use self drilling screws to attach anything to the walls. .31 hex. The green shelving is attached to the walls with the SD screws. The bottom edge of the shelving just catches the 10 block for vertical support. I can sweep under all of the shelving. Non of the shelving is sitting on the floor. Everything else show on the walls is fully supported by the roof decking, the bottom base angle and the middle girt. I have been buying the garden hose brackets from HF cutting them in half and screwing them to the walls the with the SD screws. They make excellent hooks. I have a one block exposure, 10" block, on a separate footer, between the column piers. The concrete floor on the heated side is also pined to that block. Maybe this will give you some ideas. Later.
