Back-of-House Logistics in Major Infrastructure: Avoiding Hidden Costs and Operational Bottlenecks
Major projects live and die in the last hundred metres: the loading dock that can’t take peak volume, the central store that bottlenecks replenishment, the waste system that blocks corridors, the lifts that clash with guest flows, or a supplier roster that piles trucks into a single hour. These are supply-chain problems disguised as building problems. Get BOH wrong and you inherit higher operating costs, safety risks, and reputational damage; get it right and you unlock faster turns, cleaner floors, and calmer frontline teams.
This article provides a supply-chain first approach for Infrastructure Australia and the Department of Infrastructure, Transport, Regional Development, Communications and the Arts to embed BOH excellence into planning, business cases, design briefs, procurement, and commissioning.
What goes wrong when BOH is treated as an afterthought
- Undersized docks and marshalling: trucks queue on public roads; receiving teams work around the clock to clear peaks.
- Fragmented internal logistics: too many micro-stores at wards/offices, high walk time, and misplaced responsibility for replenishment.
- Lift and corridor conflicts: goods share circulation routes with visitors, creating safety and service issues.
- Waste backflows: bins occupy valuable space; collections clash with deliveries; contamination lifts disposal costs.
- Poor vendor choreography: all deliveries arrive at similar times; security checks become a choke point.
- Catalogue sprawl and SKU misuse: no standard packs or kitting; frequent substitutions; high write-offs.
- Data blind spots: no single source of truth for deliveries, inventory, or waste—leaving KPIs to spreadsheets.
A supply-chain framework for BOH design
1) Demand and flow forecasting
- Build hour-by-hour inbound/outbound profiles for each category: F&B, clinical/maintenance consumables, linen, parcels, equipment, waste streams.
- Distinguish steady vs event-driven demand (e.g., match-day spikes, flight banks, theatre lists).
- Translate flow to dock door requirements, staging area size, and MHE (materials handling equipment) needs.
2) Dock and yard design
- Size for 99th percentile peak with time-phased smoothing; allow separate lanes for perishables, high-security items, and waste.
- Provide off-street marshalling and a pre-check zone to reduce dock dwell.
- Integrate driver self-check-in and digital queue management; design for rigid and semi-trailer geometry as relevant.
3) Central stores and internal logistics
- Right-size staging and quarantine zones; ensure temperature-controlled rooms where required.
- Use zone picking and kitting for repeatable orders (theatre packs, event bars, room-turn carts).
- Standardise min/max and cycle rules; choose two-bin/kanban for fast-movers near point-of-use.
- Align freight lifts with goods routes; separate clean vs dirty flows; set turn-back areas for trolleys to avoid corridor deadlocks.
4) Waste, recycling and back-haul
- Map waste streams (general, co-mingled, organics, clinical, cardboard, e-waste, grease traps) with segregation points and container sizes.
- Design back-haul loops: full in, empty out.
- Provide wash-down bays and contamination controls; schedule collections to avoid peak inbound windows.
5) Security and compliance
- Segregate screening and seal-check lanes for higher-risk deliveries; maintain audit trails.
- Design biosecurity and food safety receiving procedures; integrate allergen labelling and temperature checks.
6) Catalogue discipline and kitting
- Rationalise SKUs; use ready-to-use kits for recurring tasks; set pack sizes to match storage and usage cadence.
- Apply the square-root rule to hold shared safety stock centrally while maintaining service for fast-movers.
7) Digital enablement
- Implement a dock booking system with time-stamped slots and vendor SLAs.
- Use barcode/RFID for receiving and internal transfers; track DIFOT, dwell time, and exceptions.
- Connect BOH systems to BMS/BAS for temperature, lift uptime, and energy insights.
- Stand up a control tower view: inbound load, internal replenishment status, waste capacity, exceptions.
Asset-specific BOH considerations
Airports and precinct transport hubs
- Align BOH with flight banks: demand spikes must not collide with security peaks.
- Provide airside vs landside segregation, with controlled cross-over and manifest integrity.
- Ensure cold-chain and high-value store rooms are within efficient lift distance to concession clusters.
- Design night replenishment to protect daytime passenger flows.
Hospitals and health campuses
- Balance central stores vs ward stock rooms; keep clinical corridors clear with scheduled top-ups.
- Theatre kits must align to procedure lists with sterile services capacity matched to lists and tray turns.
- Separate clean vs dirty flows religiously; plan for isolation surges.
Stadiums and large venues
- Build supply plans for ingress/interval/egress waves; pre-stage event-day kegs, cartons and merch near points of sale.
- Provide cage storage for high-value lines; route waste extraction around crowd egress.
- Enable rapid pop-up concessions with standard plug-and-play BOH packs.
Government office precincts & mixed civic assets
- Design parcel lockers and mail rooms sized to modern e-commerce loads; manage courier peaks with booking.
- Coordinate tenant fit-outs to protect core goods routes and lifts.
- Plan consolidated waste and recycling with shared dock governance.
Procurement and supplier choreography
- Move from activity-based input specs to outcome-based KPIs: DIFOT to dock, dock dwell <X minutes, internal replenishment cycle time, waste contamination <Y%.
- Set delivery windows by category; restrict “free-for-all” deliveries.
- Require pre-advice (ASN) and compliance to labelling and packaging standards.
- Use panel + mini-competition for repeat buys; reserve assured alternates for critical categories.
- Bake in continuous improvement clauses linked to queue reduction, route consolidation, packaging light-weighting, and waste diversion.
Commissioning and day-one readiness
- Treat BOH as a workstream in commissioning, not an operational afterthought.
- Run mock receiving days with live vehicles; time the full flow from gate to store to point-of-use to waste.
- Validate catalogues, storage plans, labels, kitting, trolley specs, and lift scheduling.
- Execute a vendor mobilisation plan: slot allocations, badges, induction, ASN/EDI testing, packaging standards.
- Staff and train a BOH control room for the first 90 days of operations.
Sustainability and Scope 3 gains via BOH
- Cut truck kilometres through delivery consolidation and dock slotting.
- Reduce packaging via reusable tote programs and standard carton sizes.
- Lift waste diversion with correct segregation points, signage, and collection cadence.
- Monitor energy loads in cold rooms and lift banks; smooth peaks with better replenishment timing.
Risk and resilience planning
- Map single points of failure: one dock, one lift bank, one compactor—design alternates and bypass routes.
- Hold contingency mobile storage and temporary marshalling plans for special events or outages.
- Maintain surge playbooks for weather, industrial action, or supplier failure; run annual drills.
KPIs that matter
- Inbound: booked vs attended slots, truck dwell time, DIFOT to dock, non-conformance rate.
- Internal moves: pick accuracy, replenishment cycle time, lift utilisation and uptime.
- Stock health: critical stockout rate, expiry/write-off value, kit completeness.
- Waste: contamination % by stream, compactor fullness at pickup, diversion rate.
- Cost & sustainability: cost-per-case handled, energy per pallet through cold room, tCO₂e per delivery.
- Safety: near-miss frequency, corridor block time, manual handling incidents.
Link payment to a subset of these and review monthly, with quarterly improvement gates.
90-day BOH plan for new or refurbished assets
Days 1–15: Diagnose and stabilise
- Validate demand profiles; run a capacity check on dock doors, lifts, staging.
- Clean catalogues; standardise labels, pack sizes, and kit lists for top 100 lines.
- Stand up a dock booking MVP and publish slot rules.
Days 16–45: Redesign flows and contracts
- Re-lay central stores; set min/max and cycle rules; implement two-bin where suitable.
- Re-write vendor guides: ASN format, packaging, slotting, safety, waste segregation.
- Let a consolidation lane for small-parcel and low-volume suppliers.
Days 46–90: Embed and prove
- Run full-dress rehearsals with suppliers; measure dwell, replenishment time, kit completeness.
- Launch control tower dashboards; automate exception alerts.
- Lock in CI projects (queue reduction, waste diversion, packaging redesign) with benefit share.
Common pitfalls and how to avoid them
- Design to average, not peak: always size to critical peak windows and smooth with slotting.
- One lift for all goods: separate dirty/clean flows and dedicate lift time bands.
- Too many point-of-use stores: centralise what you can; automate top-ups to reduce staff time and loss.
- No vendor governance: publish a vendor handbook; enforce slot compliance and labelling standards.
- Data last: define item master, ASN, and KPI schemas before go-live.
- Waste as an afterthought: plan streams, compactor capacity, and routes from day one.

Back-of-house logistics is the operating system of an asset. It determines how calmly and safely the front-of-house performs, and it sets the trajectory of whole-of-life cost. Treat BOH as a supply-chain design challenge from day one—forecast the peaks, size the docks and lifts, standardise catalogues and kits, choreograph suppliers, digitise the flows—and major infrastructure works the way it should: reliably, efficiently, and with fewer surprises.
