Warehouse Capacity Analysis - URGENT

🚨 Critical Finding: You’re Out of Space in 2 Months

Current State

Warehouse Metrics:

  • Total: 30,000 sqft | Usable: 24,600 sqft (82%)
  • Current: 2,500 pallets | 20,000 sqft used
  • Utilization: 81.3% (already tight)
  • Storage: Floor stacking (mostly 2-high)
  • Density: 0.102 pallets/sqft
  • Max capacity (current method): 3,075 pallets

The Problem: You’re already at 81% utilization, which means you’re running tight TODAY. With 12%/month growth, you hit critical capacity next month and overflow the month after.


Capacity Forecast (12%/Month Growth)

Month Pallets Space Used Utilization Status
Now 2,500 20,000 sqft 81% ⚠️ Tight
Month 1 2,800 22,400 sqft 91% 🔴 CRITICAL
Month 2 3,136 25,088 sqft 102% 🔴 OVER CAPACITY

Timeline:

  • ⚠️ 85% critical threshold: 1 month from now
  • 🔴 100% capacity exceeded: 2 months from now
  • 📈 12-month need: 9,740 pallets (4× current capacity!)

Solution Analysis

❌ Scenario 1: Do Nothing - Overflow Storage

  • Year 1 cost: ~$192,000 (escalating rapidly)
  • 5-Year cost: $1,200,000+
  • Issues: Split inventory, operational chaos, inefficiency
  • Runway: 0 months (problem immediate)

❌ Scenario 2: Lease Additional 15,000 sqft

  • Investment: $75k setup + $1.17M/year rent
  • Year 1 total: $1,245,000
  • 5-Year total: $5,925,000
  • New capacity: 4,612 pallets total
  • Runway: Only 4 months before you hit 85% again!
  • Verdict: Expensive band-aid that doesn’t solve the growth problem

✅ Scenario 3: Selective Racking (RECOMMENDED)

  • Investment: $378,840 (one-time)
  • Annual cost: $0
  • New capacity: 9,379 pallets (+205% increase)
  • Configuration:
    • 70% racking (3-4 high): 17,220 sqft
    • 30% floor stacking: 7,380 sqft
  • Runway: 11 months before 85% threshold
  • 5-Year cost: $378,840 (vs $5.9M lease)
  • ROI: Pays for itself in 3.9 months vs leasing
  • Year 1 savings: $866,160 vs lease option

🎯 Scenario 4: High-Density Racking (Best Long-Term)

  • Investment: $640,830 (one-time)
  • Annual cost: $0
  • New capacity: 13,838 pallets (+350% increase)
  • Configuration:
    • 65% high-density (push-back/drive-in, 5-6 high)
    • 15% selective racking (FIFO items)
    • 20% floor stacking (flexibility)
  • Runway: 14 months (1.2 years)
  • 5-Year cost: $640,830
  • 5-Year savings: $5.28M vs lease
  • Best for: Sustained high growth, homogeneous SKUs

Recommendation: Scenario 3 (Selective Racking)

Why Scenario 3 over Scenario 4?

Given your urgent 2-month timeline, I recommend Scenario 3 because:

  1. Faster implementation: Selective racking is simpler, 4-6 week install vs 6-8 weeks for high-density
  2. Lower upfront cost: $379k vs $641k (easier to approve quickly)
  3. More flexible: Works with diverse SKUs, easier picking, better for variable inventory
  4. Adequate runway: 11 months gives you breathing room to reassess
  5. Immediate ROI: Saves $866k in Year 1 alone vs leasing

However, if:

  • You have homogeneous SKUs (80%+ similar items)
  • You can secure the $641k investment quickly
  • Your growth will sustain beyond 14 months
  • You want maximum long-term capacity

Then choose Scenario 4 for the superior long-term solution.


Implementation Timeline - URGENT ACTION REQUIRED

Week 1-2 (IMMEDIATE):

  • Day 1-3: Get 3 racking quotes (selective or high-density based on choice)
  • Day 4-7: Finalize layout design with vendor
  • Week 2: Order racking materials (CRITICAL - 4-6 week lead time)
  • Simultaneous: Begin inventory optimization to buy time

Week 3-6 (Lead Time):

  • Prepare installation zones
  • Plan inventory staging areas
  • Coordinate with operations for minimal disruption
  • Train staff on new system

Week 7-10 (Installation):

  • Install racking in phases (3-4 weeks)
  • Migrate inventory section by section
  • Maintain operations during transition

Month 3+:

  • Complete installation
  • Monitor utilization weekly
  • Reassess at Month 9 for next phase

Critical Path Item: ORDER RACKING BY END OF WEEK 2 or you’ll overflow before installation completes.


Risk Assessment

Risk 1: Growth Exceeds 12%/Month

  • Impact: Hit capacity sooner than projected
  • Probability: Medium
  • Mitigation:
    • Monitor weekly, not monthly
    • Set 75% utilization as warning trigger
    • Negotiate emergency overflow agreement NOW as backup
    • If Scenario 3, consider upgrading to Scenario 4

Risk 2: Racking Installation Delays

  • Impact: May overflow during installation
  • Probability: Medium
  • Mitigation:
    • Order materials THIS WEEK
    • Build 2-week buffer in timeline
    • Identify temporary overflow location (negotiate 3-month agreement)
    • Phased installation to maintain operations

Risk 3: Floor Loading Capacity Issues

  • Impact: Can’t install racking as planned
  • Probability: Low
  • Mitigation:
    • Verify floor loading specs NOW (before ordering)
    • Get structural engineer review if uncertain
    • Most modern warehouses handle 3-4 high selective racking

Risk 4: SKU Characteristics Unsuitable for High-Density

  • Impact: If choosing Scenario 4, may have picking inefficiency
  • Probability: Low (only if Scenario 4)
  • Mitigation:
    • Analyze SKU mix before committing to drive-in
    • Use hybrid approach (65% high-density, 15% selective)
    • Reserve selective areas for FIFO/fast-moving items

Bottom Line

Metric Current After Scenario 3
Capacity 3,075 pallets 9,379 pallets
Utilization 81% (tight) 27% (optimal)
Timeline 2 months to overflow 11 months runway
Investment - $378,840 one-time
5-Year Cost - $378,840 total
Savings vs Lease - $5,546,160
Payback - 3.9 months

Next Action: Get racking quotes THIS WEEK. You have ~6 weeks before overflow if you act now.


Success Metrics to Track

Post-implementation, monitor these monthly:

  1. Utilization rate - Target: 65-75% steady state
  2. Pallets stored - Track vs forecast (should match 12% growth)
  3. Picking efficiency - Should maintain or improve vs current
  4. Damage rates - Should not increase with racking
  5. Months runway remaining - Recalculate monthly with actual growth

Review trigger: If utilization hits 70% before Month 9, begin planning Scenario 4 upgrade or additional facility.
