Fundamentals of Just‑in‑Time Delivery in Construction
Origin & Principles of JIT
Just-in-time (JIT) logistics originated in manufacturing to eliminate waste by delivering materials only as needed. It emphasizes pull-based ordering, lean inventory, and supplier collaboration.
Adapting JIT from Manufacturing to Stone Supply
Applying JIT to stone requires precise planning, real-time supplier visibility, and reliable transit. The heavy, brittle nature of stone adds complexity compared to parts or assemblies.
Benefits of JIT Stone Delivery for Contractors
Lower Storage & Handling Costs
By scheduling deliveries to match installation, you avoid yard rent, forklift hire, and on-site stacking fees.
Improved Cash Flow & Reduced Waste
Pay only for stone on the dock, not in storage. Less material sits idle, reducing spoilage from weather exposure or breakage.
Enhanced Project Flexibility & Scheduling Accuracy
With on-demand stone delivery, you can adjust quantities based on real-time progress, avoiding over-ordering or last-minute rush shipments.
Choosing a Reliable Stone Supplier for JIT
Inventory Management & Real‑Time Stock Visibility
Select stone suppliers with live inventory dashboards to confirm slab availability before ordering.
Geographic Proximity & Transit Reliability
Partner with quarries or warehouses within a 200‑mile radius to minimize transit risks.
Technology Integration: EDI & Delivery Tracking
Ensure your natural stone supplier supports electronic data interchange (EDI) for orders and GPS-enabled tracking for shipments.
Service Level Agreements & Penalty Clauses
Negotiate SLAs guaranteeing delivery windows and include penalties for missed dates to protect your schedule.
Planning & Coordination for JIT Delivery
Forecasting Consumption Rates & Lead Times
Analyze installation rates (e.g., sq ft per day) and supplier lead times to build accurate delivery schedules.
Communication Protocols Between Contractor & Supplier
Establish daily check-ins and a single point of contact on both sides to confirm orders and resolve issues.
Buffer Stock Strategies & Contingency Planning
Maintain a minimal buffer (5–10% extra) to absorb minor delays without reverting to full on-site storage.
Case Study Example
ABC Builders implemented JIT on a 50,000 sq ft luxury condo project. Initial on-site stock occupied 1,000 sq ft of yard space at £15 per day rent. By shifting to JIT, they reduced storage days by 80%, saving £120,000 in yard fees and handling. Key steps included: real-time order tracking, weekly consumption forecasts, and a penalty clause in their supplier contract.

Outcomes & Insights
Lead time: 8 weeks (quoted 10 weeks)
Budget adherence: 97%
Zero slip incidents and no surface etching through six months of heavy use.
On‑site mock‑up refined grout line widths, preventing trip hazards.

Case Study 3: Miami, FL Oceanfront Hotel Pool Deck
Vetting Focus: Salt‑Air Corrosion & Thermal Comfort
A beachfront hotel in Miami Beach specified travertine pavers for its pool deck, aiming for cool touch and salt‑water resilience.
Salt‑Fog Chamber Verification: Insisted on 1,500‑hour ASTM B117 tests with < 0.1 mm surface etching.
Surface Temperature Monitoring: Vendor data showed deck remains <15 °F hotter than ambient at noon.
Guest Comfort Mock‑Up: Installed a 10 × 10 ft pilot area in peak summer to record barefoot temperature feedback.
Outcomes & Insights
Lead time: 7 weeks (quoted 8 weeks)
Budget adherence: 96%
Guests reported 20% fewer “hot surface” complaints than adjacent concrete decks.
Early temperature testing optimized finish selection for comfort.
Case Study 4: Boston, MA Historic Museum Stair Treads
Vetting Focus: Heritage Match & Slip Safety
The Boston Museum of Science restored its grand staircase using custom‑fabricated marble treads that blend with 19th‑century stone and meet ADA requirements.
Color & Vein Matching: Used spectrophotometry (ΔE < 1.5) on five quarry lots to ensure uniformity.
Slip‑Resistance Testing: Confirmed ASTM C1028 wet CoF ≥ 0.6 on honed treads.
Heritage Mock‑Up: Installed a three‑step prototype in the lobby under varying lighting to secure curator approval.
Outcomes & Insights
Lead time: 9 weeks (quoted 11 weeks)
Budget adherence: 98%
ADA inspections passed first review, and no slip incidents occurred across two seasons.
Early heritage and safety vetting eliminated costly second‑round sampling.
