| Purchasing | Storage configuration | The layout should match pallet dimensions, SKU count, inventory turnover, aisle width, forklift type, and required storage density. | A proposed layout showing bays, levels, clearances, aisles, loading areas, and emergency access routes. | Compare the design with warehouse drawings, pallet specifications, equipment data, and operational requirements. | Critical |
| Purchasing | Rack type selection | Selective pallet racking suits high SKU variety; drive-in supports high-density storage; double-deep, push-back, pallet flow, and mobile systems address specific throughput or density needs. | A written comparison of suitable rack types, capacity, selectivity, throughput, and operating limitations. | Check whether the proposed system supports the warehouse’s actual FIFO, LIFO, or batch-management requirements. | Critical |
| Purchasing | Load capacity | Every upright frame, beam level, connector, wire deck, and accessory must be rated for the intended uniformly distributed load and pallet configuration. | Stamped or signed load tables, design calculations, allowable beam deflection, and maximum bay capacity. | Confirm that capacity values are based on the actual beam spans, frame heights, bracing, pallet weights, and seismic conditions. | Critical |
| Purchasing | Material and finish | Steel grade, coating, paint system, galvanizing, corrosion resistance, and environmental suitability should be specified for the warehouse conditions. | Material certificates, coating specifications, corrosion-resistance details, and finish warranty terms. | Review certificates and inspect representative components before shipment or installation. | High |
| Purchasing | Standards and engineering compliance | The design should comply with applicable local building codes and recognized rack standards, such as ANSI/RMI MH16.1 or EN 15512, where applicable. | Engineering calculations, design basis, compliance statement, and details of the responsible structural engineer. | Obtain approval from the local authority or qualified structural engineer when required. | Critical |
| Purchasing | Seismic and environmental design | Seismic zone, wind exposure, floor slab condition, temperature, humidity, corrosion, and fire-protection requirements must be included in the design. | Site-specific design assumptions and required slab, anchoring, sprinkler, and clearance specifications. | Validate assumptions against site surveys, geotechnical information, building drawings, and local regulations. | Critical |
| Purchasing | Delivery and supply continuity | The supplier should provide a documented production schedule, packaging plan, spare-parts availability, and replacement-component support. | Lead time, shipping terms, quality-control milestones, spare-parts list, and contingency plan for delays. | Include measurable delivery milestones and remedies for non-conforming or delayed goods in the contract. | High |
| Installation | Installation method statement | Installation should be performed from approved drawings by trained personnel using a documented sequence, lifting plan, and temporary-stability controls. | Method statement, risk assessment, work schedule, equipment list, and installer qualification records. | Review documents before work begins and conduct daily site safety inspections. | Critical |
| Installation | Floor and anchorage requirements | The concrete slab must have adequate thickness, strength, levelness, and condition for the specified anchors and rack loads. | Anchor type, embedment depth, torque requirements, slab tolerances, and installation inspection procedure. | Inspect anchor locations, torque, embedment, damaged concrete, rack plumb, and baseplate contact. | Critical |
| Installation | Handover documentation | The completed system should be handed over with as-built drawings, load plaques, inspection records, manuals, and maintenance instructions. | Signed installation checklist, non-conformance log, as-built layout, component schedule, and operating instructions. | Release final payment only after document review and acceptance inspection. | High |
| Safety | Load identification | Capacity plaques must be visible at operating level and state allowable loads, beam levels, bay configuration, and any restrictions. | Plaque format, location plan, and process for updating ratings after any layout or loading change. | Verify plaques against approved engineering calculations and the installed configuration. | Critical |
| Safety | Impact protection | Column guards, end-of-aisle barriers, guardrails, backstops, and bollards should be used where forklift impact or falling-load exposure exists. | Protection layout, impact-rating information, anchoring details, and replacement specifications. | Inspect protection devices for secure anchoring, deformation, and adequate coverage of exposed members. | Critical |
| Safety | Pallet and load compatibility | Pallets must be suitable for the beam, support, wire-deck, pallet-flow, or drive-in arrangement and must not exceed rated dimensions or weight. | Pallet specifications, support conditions, maximum overhang, load stability limits, and approved load-unit examples. | Conduct a physical trial with representative pallets and the intended handling equipment. | Critical |
| Safety | Fire and emergency clearances | Rack layout must preserve required sprinkler clearance, fire exits, fire lanes, pedestrian routes, and access for emergency response. | Fire-protection coordination drawings and confirmation of required clearances under local codes. | Obtain approval from the fire-protection consultant or responsible authority before operation. | Critical |
| Safety | Inspection standard | A documented inspection program should identify damaged, displaced, overloaded, corroded, or unauthorized-modified components. | Inspection checklist based on applicable requirements, including EN 15635 or local equivalent where relevant. | Use trained internal inspectors and arrange periodic expert inspections at an interval defined by risk assessment and local rules. | Critical |
| Maintenance | Routine inspection frequency | Operators should perform visual checks during normal work, with formal documented inspections at a frequency determined by use, risk, and applicable regulations. | Inspection schedule, reporting forms, escalation procedure, and responsible-person training requirements. | Audit completed records and confirm that defects are tracked to closure. | Critical |
| Maintenance | Damage-response procedure | Damaged components should be unloaded, isolated, reported, and repaired or replaced using approved parts; field straightening or welding should not be performed without engineering approval. | Red-tag procedure, repair criteria, replacement-part identification, and engineering approval process. | Review incident records and verify that damaged racks are not returned to service without documented authorization. | Critical |
| Maintenance | Spare-parts and repair support | Common replacement items should remain identifiable and available, including beams, uprights, connectors, anchors, guards, and safety accessories. | Parts catalogue, identification system, minimum stock recommendations, warranty terms, and service response targets. | Test the ordering process and confirm compatibility of replacement components with the installed system. | High |
| Maintenance | Change management | Any change to beam levels, bay configuration, pallet weight, forklift type, aisle width, or building conditions should receive documented review before implementation. | Modification approval workflow, revised calculations, updated drawings, and new capacity plaques. | Audit changes against the approved configuration and maintain a controlled revision history. | Critical |
| Supplier Evaluation | After-sales service | A qualified local or regional service network should support inspections, repairs, training, documentation updates, and urgent damage response. | Service coverage by country or region, response times, technician qualifications, training options, and escalation contacts. | Request service references for comparable warehouse environments and review service-level agreements. | High |
| Supplier Evaluation | Total cost of ownership | The evaluation should include equipment, engineering, freight, installation, anchoring, protection, inspection, repairs, spare parts, downtime, and future expansion. | Itemized quotation, exclusions, warranty coverage, estimated maintenance cost, and expansion pricing. | Compare lifecycle cost rather than purchase price alone, using the same scope and capacity assumptions. | High |
