Delivery access should be documented before a buyer requests a final quotation, schedules freight, or confirms a placement plan. A chamber that fits the final room may still be unable to pass through a gate, doorway, corridor, elevator, landing, or turn along the route. This checklist helps buyers create a site record that a supplier, carrier, installer, and local professionals can review against the exact configuration.
This is a procurement and logistics checklist, not an installation design, structural opinion, or code determination. Do not use it to infer a universal minimum doorway, corridor, elevator, stair, floor, or turning dimension. Confirm the selected model's current shipping documents, handling instructions, and site requirements with the supplier and the parties responsible for the building and delivery scope.
1. Start With Supplier Dimensions and Handling Data
Request a dated document set for the exact quoted configuration before measuring the building. Product photographs, a similar model's brochure, and an older quotation are not sufficient for route planning. The O2BAY hard-shell chamber collection can help identify options, but the supplier must confirm the dimensions and handling information that apply to the selected unit.
Record each dimension as supplied
- Model, configuration, options, drawing revision, and quotation date.
- Crated length, width, height, mass, package count, and center-of-gravity information when supplied.
- Uncrated length, width, height, mass, support points, and the orientation required for movement.
- Handling points, lifting restrictions, permitted equipment, and instructions for unpacking.
- Separate dimensions and movement requirements for compressors, controls, oxygen-source equipment, coolers, and other accessories.
Ask the supplier to identify which values are maximum shipping dimensions, which values are assembled dimensions, and which values exclude removable packaging or accessories. The RFQ checklist provides a broader framework for requesting configuration-specific drawings, packing lists, and written exclusions.
2. Confirm Packaging, Unloading, and Exterior Access
Trace the route from the carrier's delivery point to the final placement area. Record whether the vehicle can approach the unloading location, where a crate may be set down, and whether the site has restrictions on vehicle type, delivery hours, loading-dock use, or temporary access. The carrier should confirm its contracted scope; do not assume freight includes unloading, rigging, internal movement, or debris removal.
Document the exterior route
- Delivery address, loading area, curb, driveway, gate, and parking or staging location.
- Vehicle approach restrictions, overhead obstructions, slopes, surface changes, and weather exposure relevant to the planned delivery date.
- Gate opening width and height, including posts, hardware, bollards, and fixed obstructions.
- Path width, surface condition, grade changes, drainage features, and locations where handling equipment must turn or stop.
- Permissions needed for loading areas, elevators, doors, railings, landscaping, or temporary building access changes.
OSHA's materials-handling requirements are a useful prompt to identify safe-clearance and housekeeping questions for a workplace delivery plan. They do not select a handling method or establish that a particular site route is suitable for a chamber.
3. Measure Doors and Corridors at Their Tightest Points
Measure every opening in the actual travel orientation, including exterior doors, vestibules, interior doors, corridor pinch points, and the final room entry. Record the clear opening rather than the nominal door size. Include frames, panic hardware, closers, handrails, trim, sprinkler piping, lighting, and other fixed features that reduce the available path.
Use a repeatable measurement record
- Location identifier and a photograph looking in both travel directions.
- Clear width and clear height at the narrowest usable point.
- Door swing, opening angle, removable parts, and the party authorized to approve any temporary removal.
- Corridor width, ceiling restrictions, wall projections, and openings immediately before or after a turn.
- Measurement date, tool used, person who measured, and any uncertainty that needs confirmation.
Compare the record with the package and uncrated orientation only after the supplier has confirmed the permissible handling method. Do not assume a crate can be opened outdoors, a door can be removed, or equipment can be tilted to reduce the required opening.
4. Survey Elevators, Stairs, Landings, and Turning Clearance
Elevators and stairs introduce different limits from a straight corridor. For an elevator, collect the car interior dimensions, door opening, rated capacity, floor protection requirements, reservation process, and building operator contact. For stairs, record the full flight, rise changes, landings, headroom, handrails, and the proposed handling method. A building owner or qualified local professional should determine whether the structure and access arrangement can support the planned movement.
Map every change in direction
At each corner, landing, vestibule, or room entry, sketch the available footprint and mark the exact obstacles that constrain movement. A single width measurement does not describe whether a rectangular package can rotate through a turn. Send the sketch and photos to the supplier or appointed movement specialist for a configuration-specific review.
OSHA's walking-working surfaces requirements can help frame questions about route condition and obstructions in workplaces. They are not a route approval, a structural review, or a substitute for the manufacturer's handling instructions.
5. Check Thresholds, Floors, and Final Placement
Record thresholds, ramps, floor transitions, uneven surfaces, drainage channels, expansion joints, and any location where wheels, skates, or lifting equipment would cross a change in elevation. Note the proposed unpacking point and whether packaging waste can be removed without blocking circulation. Do not select a floor-protection method, ramp, or load-spreading arrangement from a generic checklist; confirm it with the movement provider and building owner.
Prepare the final placement record
- Scaled room plan showing the chamber, doors, controls, accessory equipment, utility points, and service areas.
- Exact operating mass, footprint, support-point data, and other loads supplied for the selected configuration.
- Floor construction information and the contact for a qualified structural review where one is required.
- Utility and ventilation information to be reviewed under the current model documents.
- Access needed after placement for assembly, commissioning, service, inspection, and routine building circulation.
For related site-readiness questions, use the hyperbaric chamber installation requirements checklist. It separates delivery planning from electrical, ventilation, oxygen, and professional-review questions that depend on the exact site and configuration.
6. Capture Evidence Before Requesting Shipment
Photographs are useful only when paired with measurements. Give each image a location label and include a tape measure, laser reading, or other visible reference where practical. Keep the originals with a route sketch, dimension table, date, and the name of the person who recorded the information. Mark assumptions and unresolved areas instead of treating them as confirmed.
Where a buyer needs more detail about model records, use how O2BAY hyperbaric chambers are built and documented to organize requests for drawings, packing information, manuals, and traceable supporting documents. ASME's PVHO-1 scope page can help a buyer identify documentation topics to discuss with a supplier; it does not verify a model, a delivery plan, or a building condition.
7. Assign a Delivery Responsibility Matrix
| Activity | Evidence to request | Responsible party to confirm |
|---|---|---|
| Configuration and package data | Current drawing, packing list, mass, handling points, and instructions | Supplier |
| Freight and delivery point | Freight terms, carrier contact, delivery appointment, and included scope | Buyer and carrier |
| Unloading and exterior movement | Equipment plan, staging location, route survey, and property permissions | Buyer, carrier, and movement provider |
| Internal route and building access | Door, corridor, elevator, stair, turn, and obstruction record | Buyer and building owner |
| Floor and final placement | Model load data, room plan, floor information, and required reviews | Buyer and qualified local professionals |
| Assembly and handover | Included services, prerequisites, acceptance records, and open-items log | Supplier, installer, and buyer |
Make responsibility explicit in the quotation or project plan. The supplier may provide model data, while a carrier controls transport scope, a building owner controls access permissions, and local professionals review site-specific work. A blank cell in the matrix is an unresolved procurement risk, not an implied obligation.
8. Hand Off a Complete Measurement Package With the RFQ
Send the supplier one controlled package: the selected configuration, supplier document revision, route sketch, dimension table, photographs, delivery address, final room plan, proposed unloading point, and a list of open questions. Ask for a written response identifying assumptions, exclusions, required equipment, permitted handling orientations, and any missing information. The hyperbaric chamber cost buyer's guide can help separate equipment, freight, installation, and owner-provided costs before quotes are compared.
Buyers comparing formats should also review the hard-shell versus portable comparison and the portable chamber collection. Route requirements differ by model, package, and equipment scope, so neither resource replaces current model-specific shipping data.
