Every machine relocation lives or dies on one unglamorous activity: the access and route survey. Before a single bolt is loosened, you need to know exactly how a 12-tonne machine will leave its current foundation, travel through the building, cross the yard, load onto a trailer, and arrive at its new position. Skipping this step is the single most common reason relocation projects blow their budget and schedule.

This guide explains what a proper site survey covers, how to document it, and the decisions it drives — so your move runs without surprises.

Why the Survey Comes First

Machinery doesn't fail to move because it's too heavy. It fails because a doorway is 50 mm too narrow, a mezzanine can't take the point load of a forklift, or a crane can't be positioned close enough to reach the load. These problems are cheap to solve on paper and ruinously expensive to discover on moving day.

A good survey turns unknowns into a method statement. It confirms that every leg of the journey — origin, internal transit, external transit, and destination — is physically and structurally possible with the equipment you intend to use.

Surveying the Origin Point

Start where the machine sits today. Capture:

Exact footprint and extraction direction. Which way can the machine be pulled out? Is there space to attach rollers, skates or a hydraulic gantry?
Surrounding obstacles. Pipework, cable trays, adjacent machines, columns and racking that must be removed or protected.
Headroom. Overhead clearance for lifting, tilting or upending the machine. Note sprinklers, ducting and lighting.
Energy isolation points. Where electrical, pneumatic, hydraulic and process connections terminate, so disconnection can be planned safely.

Measure twice and record dimensions in writing and photos. Assume nothing is standard.

Weight and Center of Gravity

Confirm the machine's mass and center of gravity from the manufacturer's data or by calculation. This feeds directly into rigging choices, floor loading checks and crane capacity. An off-center lift that looks fine on paper can tip or swing dangerously if the center of gravity was guessed.

Mapping the Internal Route

The path from the machine to the loading door is where most surprises hide. Walk it physically, with a tape measure and a camera.

Door and aisle widths and heights. Record the narrowest point of every opening, including frames, rolled-up shutters and protruding hardware.
Floor condition and load capacity. Can the floor carry the combined weight of the machine plus the transport equipment on a small contact area? Expansion joints, drains, trench covers and floor channels are weak points.
Floor level changes. Ramps, thresholds, dock levelers and gradients affect skating and forklift operations.
Turning radii. Long or awkward loads may not negotiate 90-degree corners even if each aisle is wide enough. Plan the swing.
Mezzanines and basements. Point loads from jacks or forklifts can exceed what suspended floors tolerate.

For tight routes, a simple scaled drawing or 3D scan lets you simulate the move and prove clearance before committing.

External Access and Craneage

Once outside, the variables multiply.

Yard surface and ground bearing capacity. Cranes and heavy trailers impose enormous ground pressures through outriggers and axles. Soft ground, buried services, drains and voids must be identified and mats or spreaders planned.
Crane positioning. Confirm the crane can stand where its boom reaches both the load and the trailer, with clearance from the building, power lines and overhead obstructions.
Overhead hazards. Power lines, cables and canopies limit boom and load positions.
Loading area. Space for the trailer, the crane, and safe exclusion zones around the lift.

If an external crane is involved, the survey should capture everything the lift plan needs: lift radius, load weight, and ground conditions.

Transport Route Across Europe

For cross-site or cross-border moves, the public road route needs its own survey, especially for oversized or over-dimensional loads.

Height, width and length restrictions. Bridges, tunnels, low cables and narrow village streets.
Weight limits. Bridge and road axle-load restrictions.
Permits and escorts. Abnormal-load transport requires permits that vary by country and can take weeks to obtain.
Timing windows. Many jurisdictions restrict heavy transport to certain hours or days.

Identifying the transport envelope early tells you whether the machine must be partially dismantled to fit legal limits — a decision that cascades back into the dismantling plan.

Surveying the Destination

The new location deserves the same scrutiny as the origin, in reverse.

Foundation readiness. Is the floor slab, pit or anchor layout prepared and cured? Confirm load-bearing capacity for the operating machine, not just the static weight.
Service availability. Power, compressed air, water, drainage and data must reach the final position in the right ratings and locations.
Final positioning access. Can you get the machine to its exact spot, or will it need to be skated and jacked into place in a confined area?
Clearances for commissioning. Room to level, align, connect and test — and for operators and maintenance access afterward.

Turning the Survey Into a Plan

A survey is only valuable when it produces decisions and documents:

Method statement and risk assessment (RAMS) describing each step, the equipment used, and the controls in place.
Equipment list — crane class, skates, gantries, slings and shackles sized to the verified weight and center of gravity.
Dismantling scope — what must come off the machine to clear routes and meet transport limits.
Protection plan — floor protection, edge padding and barriers for identified pinch points.
Contingencies — alternative routes, backup equipment and clear go/no-go criteria.

Common Oversights to Avoid

Measuring the opening but forgetting the swing of the load into it.
Checking floor capacity but ignoring the concentrated point load of a jack.
Confirming the crane's capacity but not where it can physically stand.
Assuming the destination foundation is ready when curing or anchoring is unfinished.
Leaving abnormal-transport permits to the last week.

The Bottom Line

A disciplined access and route survey is the cheapest insurance in any relocation. A day or two of careful measurement, structural verification and route walking prevents the stalled moves, damaged assets and emergency re-planning that turn a tidy project into a costly one. Whether you move one machine across the floor or an entire line across borders, let the survey — not the moving day — surface the problems. With the physical path proven and documented, the lift, transport and re-installation become a sequence of controlled, predictable steps.
