AS/RS warehouse: six interfaces between building and machine to lock down before signing the equipment purchase

Investors often receive an AS/RS proposal listing the number of pallet positions, rack height and nominal speed. That is only the machine side. A system can operate only if the warehouse building takes the correct loads, has the correct geometry and meets the safety requirements. If the two parties prepare two independent sets of documents, the overlaps easily turn into construction variations at the point when they are hardest to fix.

1. Geometry and tolerances

Fix pallet and load dimensions, usable storage height, rack modules, maintenance aisles, pallet in/out transfer space and safety clearances for the specific configuration. The warehouse column grid cannot be chosen solely for structural economy in the hope that the racking will adapt. Interface drawings with dimensions confirmed by both the engineering consultant and the equipment supplier are required.

2. Loads and foundations

Rack loads, concentrated loads at column bases, dynamic machine loads and flatness requirements are not covered by a single generic "warehouse floor load" figure. The floor slab, foundations, anchor connections and rails must be checked against the data of the selected equipment; all provisional assumptions must be clearly recorded so they do not accidentally become construction data.

3. Power, data and shutdown modes

The power supply capacity, cabinet locations, cable routes, control network, power for the safe state and the recovery procedure after a power failure must be agreed. The question is not just "how many kW does the machine draw", but which stock remains accessible when one zone stops and in what sequence the system returns to operation.

4. Fire protection and maintenance access

Tall racking, stored goods and aisle layout change the problem of detection, firefighting and incident access. This must be reviewed for the specific project by the designer and the competent review authority; renderings or equipment catalogs cannot confirm that a fire protection solution meets requirements. Provide access routes, maintenance positions and escape routes on the very first layout.

5. Buffer zones and real throughput

The nominal speed of a stacker crane or shuttle is not the outbound throughput of the whole warehouse. Docks, conveyors, buffer zones, counting and the dispatch software can all be bottlenecks. Give suppliers peak-hour order data, the SKU profile and inbound–outbound rules so they can present throughput that accounts for intermediate repositioning and a scenario with one machine down.

6. Responsibility boundaries and handover

Before signing, prepare an interface matrix: which items are designed by the engineering consultant, which data is provided by the supplier, what the installation contractor builds, who commissions the integration and who signs the acceptance. If a rack anchor, sleeve opening or power supply point has no owner, the resulting extra costs are already built into the project.

What deliverables should the project owner require? A set of interface drawings confirmed by both sides, load and tolerance tables, a throughput simulation based on operating data, a list of open assumptions and a total cost table covering the building as well as the equipment. CGD handles the building and the infrastructure around the equipment and does not sell AS/RS; this allows suppliers to be compared on the same basis.
