Warehouse performance depends on decisions made before the shell is designed. Storage layout, truck movements, equipment, power, floor tolerances, and site constraints should be tested together. These questions are especially important when the future tenant or operating process is still changing.

1. Choosing clear height without a storage plan

Clear height affects usable rack levels and building cost, but a universal target is misleading. Ask a racking designer and fire protection engineer to review the commodities, pallet size, lift equipment, aisle layout, and sprinkler approach. Compare the added usable capacity against the cost of each height option.

2. Assuming today’s electrical load will be enough

Conveyors, charging, automation, refrigeration, and future tenants can change demand. Have an electrical engineer prepare a load study and ask the utility about available service and upgrade steps. Reserve capacity or space for expansion when the business case supports it; oversizing every component may waste capital.

3. Drawing docks before testing truck movements

Dock count, trailer size, circulation, staging, grades, and public-road access should be modeled for the actual fleet. A fixed court-depth rule cannot account for every trailer mix and site. Use a vehicle-turning study and review local access requirements before freezing the building footprint.

4. Treating the slab as generic concrete

Floor thickness, joints, reinforcement, flatness, and subgrade depend on rack loads and material-handling equipment. Ask the equipment supplier and structural engineer for a coordinated floor specification, then establish testing and acceptance criteria before the pour.

5. Leaving site investigations until after purchase

Geotechnical conditions, stormwater, wetlands, utilities, zoning, and off-site improvements can alter feasibility. Commission proportionate due diligence and identify approval conditions before the purchase becomes unconditional when the transaction allows it.

6. Reserving expansion space without testing it

An expansion area must still satisfy setbacks, stormwater, fire access, utilities, structure, and circulation. Test a future phase on the site plan rather than assuming an end wall can simply be removed later.

7. Compressing design before operations are defined

Issue a written operating brief: products, storage method, throughput, staffing, equipment, safety needs, future flexibility, and target opening date. Review design milestones with operations, facilities, and the builder. Changes are easier to evaluate when the assumptions are visible.

8. Copying code assumptions from another warehouse

High-piled storage, commodity classification, sprinkler design, truck routes, and local land-use rules need project-specific review. Confirm the adopted code and agency requirements with the design professionals and local authorities.
