From a 75,000 m² automotive park to a single packaging workshop. What changes between them is the crane, the process and the floor — and the frame follows, not the other way round.
A workshop is not a box with a roof. It is a frame that has already agreed with a process — and the process usually wins.
Duty class, hook height, runway length and the wheel loads they produce. Two sheds of the same area with different cranes are not the same building, and the column decides which one you get.
Mezzanines, suspended plant, vibrating equipment, tanks sitting on a steel floor. Every one is a point load that has to be in the model before the frame is sized.
Slab thickness, joints, drainage falls, and the flatness a forklift or a racking system actually needs. The steel frame sets the columns; the floor sets whether the building works.
Most factories we build are one phase of three. A bolted joint that can take another bay later costs nothing now, and saves a rebuild in five years.
Sprinkler mains, ducting, cable trays, compressed air, dust extraction. They hang from the same purlins as the roof, and they are the first thing to collide with a brace.
None of them is about steel. All of them decide how much steel the building needs.
Machines, lines, furnaces, presses. Weight per square metre is the first number that changes everything else.
A suspended conveyor, an air-handling unit or a monorail turns a roof into a loaded structure. It has to be declared, not discovered.
Docks, ramps, door widths, turning circles for a 12 m trailer. The traffic decides the layout before the span does.
One column in the wrong place stops a line. Tell us the aisle and the clearance, and the span follows from it.
Another bay, another crane, another floor. Reserved capacity is cheap; a rebuild is not.
Walkways, fall protection, and a safe route to the plant on the roof. Designed in, it is a detail; added later, it is a cost.
Client names are the clients’ own. Areas are floor area; contract values are not shown.
A layout, a crane duty and the site is enough for a first structural answer — and for telling you which of your assumptions costs the most.
