A machinery move survey is a walkthrough of the route and both sites before a rig job is quoted. Riggers confirm real weight and center of gravity against the OEM manual, measure every door, corridor, and elevator on the route, check floor load capacity, and verify utilities at the destination. Anything skipped surfaces on move day as a delay or a change order instead.
A rigging quote built without a site visit is a guess with a number attached. It might be close. It might also be missing the one door in the building that is four inches narrower than the machine, or the one section of second-floor slab that was never rated for a five-ton press. The survey is the step that turns a guess into a plan — and it is usually a half-day of measuring and photographing that saves a week of improvising later.
None of this is complicated work. It is just work that has to happen before the crew shows up, not while they are standing in the doorway holding a machine that no longer fits.
What is a machinery move survey?
It is a documented walkthrough of the machine, the route out of the old building, and the route into the new one, done before a job is scheduled. A rigger walks both sites with a tape measure, a camera, and the OEM drawings if they exist, and comes away with a real weight, a real path, and a list of anything that will need special handling. That document is what the rigging plan, the crew size, the equipment list, and the schedule all get built from.
It is not the same as a sales walkthrough. A sales visit answers "roughly what will this cost." A survey answers "will this machine actually get out of this building and into that one, and what has to be true for that to happen."
What weight and dimension data does a survey need?
The nameplate is a starting point, not an answer. Surveys pull the actual shipping weight and center of gravity from the OEM manual or drawing whenever one exists, because nameplates round, omit attachments, and — on machines like injection presses — describe something else entirely, like clamp tonnage instead of mass. Where no manual survives, the crew works the weight from material, volume, and comparable machines, and treats that number as an estimate to be confirmed on the scale, not a fact to rig against.
Center of gravity matters as much as total weight. A machine that is heavy on one end — a lathe with the headstock loaded, a press with the clamp end far heavier than the injection end — needs pick points and skate positions chosen around that offset, not the geometric middle. Getting this from a drawing beats guessing it from the outside every time.
What gets measured and recorded on the walk
- Confirmed weight and center of gravity, sourced from the OEM manual where one exists
- Overall length, width, and height in the machine's actual travel configuration, not its brochure dimensions
- Every door, corridor, and turn on the route, with width, height, and swing
- Floor and slab load capacity along the path and at both resting points
- Elevator car dimensions and rated capacity, if the route uses one
- Utilities at the destination — power, water, air, drainage — matched against what the machine needs
- Dock height, load-out clearance, and where a crane or forklift would actually be able to set up
Why do door and corridor measurements matter more than the floor plan suggests?
Because a floor plan shows a door as a rectangle, and a rigger has to know the rectangle that is actually there once the frame, the closer arm, the fire strip, and the trim are accounted for. A door listed at 42 inches on a drawing can be 39 in practice. A machine that clears the opening square will not clear it on the diagonal it has to travel to make a turn into the next corridor, and a machine on skates does not turn on a dime — it needs a swept radius calculated from its actual footprint, not its width.
The survey walks the whole route, not just the two ends, because the tightest point decides whether the machine moves at all. That includes checking for anything overhead — sprinkler heads, conduit, low beams, mezzanine framing — that a machine's actual travel height would clip even though the floor-level clearance looks fine.
How is floor loading checked before a machine crosses it?
The survey compares the load the machine will impose against what the floor was built to carry, at every point along the path — not just where it will finally sit. A machine sitting still spreads its weight over its base or over skates and cribbing. The same machine on machinery skates concentrates that weight onto four small steel wheels, and a machine picked by forklift concentrates it further, onto a smaller footprint at the tire contact points. Each of those is a different loading condition, and each one has to clear the floor's rated capacity, including any safety margin already built into that rating.
Second floors, mezzanines, and loading docks are where this actually bites. A ground slab is usually rated for a lot; an upper floor in an older building was designed for its intended use — office loads, light storage — and was never meant to see a rigged machine at all, let alone one riding on skates. Where the survey turns up a floor that will not carry the load as planned, the fix is route planning: plate to spread the load, a different path, or moving the machine dismantled into smaller pieces — not hoping the floor holds.
How do elevator ratings factor into a machinery move?
An elevator has two separate limits, and a survey checks both: the rated load capacity of the car, and the physical dimensions of the car and its door opening. A machine can be well under the weight rating and still not fit through the door, or fit through the door and still exceed the rating once it is loaded with its skids and rigging hardware. Both numbers come off the elevator's data plate or the building's elevator maintenance records, not off a guess based on how big the lobby looks.
Freight elevators built for exactly this kind of load are the exception, not the rule in most commercial and light-industrial buildings — a lot of buildings only have passenger elevators, which are rated far lower and sized for people, not machines. Where the machine cannot go by elevator, the survey is what surfaces that early enough to plan a crane pick through a window or roof opening instead, rather than discovering it with a crew and a machine already on site.
What utilities does the survey check at the new location?
Whatever the machine needs to run, confirmed as actually present and actually matching before the machine arrives, not assumed because "there's an outlet over there." That means the right voltage and phase for the machine's real electrical draw, compressed air at the pressure and volume the machine specifies, water and drain connections sized correctly, and — for anything that generates heat or fumes — ventilation that matches what the old location had. A machine landing at a spot with the wrong power feed does not run; it sits there until an electrician gets scheduled, which is downtime nobody budgeted for.
This is also where the survey checks the floor itself at the resting point specifically — not just along the route — since that is where the machine will sit under full weight indefinitely rather than passing through for a few minutes on skates.
What turns into a change order when the survey gets skipped?
The same handful of things, almost every time. A door or corridor that measures narrower in person than on the drawing, discovered with the machine already partway down the hall. A floor along the route that was never rated for a rigged load, discovered when skates start to track marks into it. An elevator that is rated heavy enough but built two inches too narrow for the machine's crated width. Utilities at the new site that do not match what the machine actually needs, discovered after it is already set and leveled. Every one of these is a five-minute check on a survey and an expensive, schedule-wrecking problem once a crew and a machine are already committed to a route.
The pattern holds for a single machine and it holds harder for a whole plant relocation, where dozens of machines are each running this same check against the same handful of doors, corridors, and elevators — one bad measurement early in the survey can cascade into a sequencing problem for every machine that was supposed to follow it out the same route.
Who actually does the survey, and what do they bring?
A rigging supervisor familiar with the specific type of machine, ideally the same person or crew who will run the move, walks the site with a tape measure, a laser distance meter, a camera, and — where they exist — the machine's OEM drawings and the building's floor plans and structural information. The output is not a narrative; it is a dimensioned record: measured clearances, photographs of every pinch point, a confirmed or estimated weight and center of gravity, and a marked-up route from the machine's current position to its new one.
That document is what makes the rest of the job predictable. It is what a crew size and equipment list gets built from, what tells whether the machine moves on skates and jacks or under a crane, and what the transport plan — moved between sites through our licensed broker and carrier partners — gets sized around once the machine is out the door.
Bottom line
- A survey confirms real weight and center of gravity from the OEM manual, not the nameplate or a guess.
- Every door, corridor, and turn on the route gets measured as-built, including the diagonal a machine needs to turn.
- Floor loading is checked for every condition the machine will actually create — sitting still, on skates, on forklift tires.
- Elevators are checked on two independent limits: rated capacity and physical opening size.
- Utilities at the new site are confirmed to match the machine's actual requirements before it lands.
- Skipping any of this does not remove the problem — it just moves the discovery to move day, as a delay or a change order.
