A route survey should explain how the spa gets from its current position to the vehicle and from the vehicle to the new pad. Record the whole path, including the space around each restriction.
Draw the route in order
Start with the proposed loading position and follow the path to the tub. Mark gates, doors, turns, changes in level and surface transitions. Make the same simple record for delivery.
You do not need a technical drawing. An ordered sketch with measurements and corresponding photographs is more useful than several disconnected close-ups.
Measure clear openings and working space
Record the narrowest usable width through each gate or door and the overhead clearance. Include hinges, latches, eaves and other projections.
Ask the provider about the permitted transport position and the extra dimensions contributed by equipment. Hot Spring notes that dolly height changes overhead clearance.[1] Leave assessment of the handling envelope to the provider rather than comparing only one cabinet measurement.
Check every turn
A tight corner can require space on both sides of an opening. Photograph the approach and exit, note fixed obstacles and show whether the tub could be straightened after passing the gate.
Use the tight-gate guide if the opening is the main concern. Do not assume a successful straight passage proves the rest of the route.
Describe surfaces and level changes
- Record the number and form of steps, thresholds or raised edges.
- Identify slopes and the direction the route follows them.
- Show soft ground, loose gravel and drainage channels.
- Note sections affected by rain, ice or construction.
- Identify where equipment or people would have restricted space.
Do not classify a surface as suitable simply because a person can walk across it. The load and handling equipment need their own assessment.
Record permissions and vehicle access
Identify parking arrangements, locked gates and shared or neighboring property. Ask who can approve any proposed barrier work and who would reinstate it.
For a separate lifting assessment, show overhead obstructions and possible setup areas, but do not prescribe the operation. Manufacturer guidance recognizes that some sites need a crane; feasibility belongs with the operator's site assessment.[1][12]
Finish with the destination's working position
Mark the spa footprint and equipment-panel side, and confirm that the foundation, cover movement and service access have been assessed. An open route to a patio does not prove the installation is ready.
The destination checklist covers that separate decision.
Update the record when something changes
Send current measurements and photographs if weather, fencing, landscaping or another delivery alters the route. Keep the original agreed scope and the revision together.
Use the alternative-route guide when the survey identifies a problem. Include the critical measurements and constraints in the moving inquiry so the assessment is based on the complete path.
