Define the transport unit before surveying the route
The verified GOODCASE catalog lists a custom Yamaha QL5 Flight Case with reinforced structure, protective hardware and OEM/ODM B2B customization support. It does not publish an order-specific case size, loaded weight, internal arrangement or opening mechanism. Start with the buyer's actual QL5 configuration and record everything travelling in the same unit, including fitted accessories, separately packed items and cables.
Create a provisional packed-envelope sheet using measured console inputs and the supplier's proposed drawing. Keep measured, proposed and unconfirmed values visibly separate. Do not begin from a generic QL5 name or a previous case: a changed console revision, accessory set or storage requirement can change the transport unit that must pass through the building.
Turn the access route into a pass-or-review record
Map the complete journey from vehicle position to operating area. Record usable width and height at doors, lifts and vehicle openings, plus thresholds, ramps, turns, floor transitions and points where orientation changes. Note the measurement method and add photographs with a scale reference. Handles, door closers or a tight approach can reduce the usable opening below its nominal dimensions.
Compare every constraint with the supplier's proposed packed envelope, external handling points and loaded weight. Leave a constraint marked for review while the proposal is not final; do not invent a clearance or staffing rule. The handling plan should state where direction changes occur, whether the route permits the proposed orientation and which site restrictions require resolution before design approval.
Plan the setup zone and cable changeover
At the venue, draw a setup zone instead of checking only whether the packed case fits. Show the final console position, operator side, cable-source side, temporary location for removed covers or parts, and areas required by people and nearby equipment. If the supplier proposes a moving assembly, request its complete swept envelope and operating steps; the hydraulic-flip site category does not prove that this QL5 product contains a hydraulic mechanism.
Write the changeover sequence from parked case to ready console and back. Identify which cables connect before positioning, which connect afterward, where plugs and service loops sit, and when the route must be clear. Review with representative connectors. This exposes conflicts between cable access, cover storage and operator reach without claiming an unsupported universal clearance.
Accept the first unit against observable evidence
Before approving repeat quantity, agree a first-unit checklist. Verify the QL5 configuration and orientation, fit of listed accessories, intended contact and no-contact areas, access to required controls and connectors, movement of proposed case parts, closure without trapped cables, and passage through the recorded route. Use dated photographs and identify every deviation from the approved drawing.
Send GOODCASE the console record, accessory list, route survey, setup-zone drawing, changeover sequence, quantity and destination as one RFQ pack. Ask the quotation to separate included items, options, exclusions, packing, delivery basis, lead time and change terms. Materials, tests, ratings, mechanism details and commercial promises are valid only with order-specific supplier evidence; changes affecting route or workflow reopen the relevant check.
