Case study: Mega-Project General Contractors

How a Fortune 500 Contractor Uncovered 20% in Rental Savings Through Logistics Optimization — Without Renegotiating a Single Rate

The Customer

A Fortune 500 mechanical, controls, and infrastructure contractor operating large-scale projects across the U.S., with more than $20 million in annual equipment rental spend.

Their procurement organization was highly sophisticated, featuring:

  • Strong, nationally negotiated rate cards
  • Strict supplier onboarding and compliance processes
  • Regionally assigned preferred vendors
  • A centralized enterprise purchasing workflow
  • Published internal pricing and approved supplier lists
  • Open booking access for operations teams once approvals were complete

On paper, the program was airtight.

 

 

Their Challenges

Despite best-in-class procurement discipline, significant cost inefficiencies remained — not in pricing, but in field execution.

1. Inconsistent Supplier Selection Across Regions

Even with negotiated agreements in place:

  • Different regions used different suppliers for similar scopes of work
  • Preferred vendors were not consistently selected
  • Field teams made booking decisions independently
  • Supplier usage varied widely based on habit or urgency

This created regional cost variability that had nothing to do with rates.

 confirming:

  • What was on rent
  • Who ordered it
  • When it was due off
  • Whether it was still needed

Idle assets quietly cost the company money.

2. Hauling & Logistics Variance Driving Hidden Cost

Transportation decisions were not optimized:

  • Hauling distances varied dramatically from site to site
  • Equipment was sourced from non-closest branches
  • Mobilization costs fluctuated widely
  • No standardized logic existed for distance-based decision-making

Even with strong rate cards, hauling inefficiencies materially inflated total spend.

3. Limited Visibility Across Hundreds of Jobsites

With hundreds of active projects operating simultaneously:

  • Coordination occurred through emails and texts
  • Supplier communication was manual
  • No real-time view existed across regions
  • Procurement-approved vendors did not always match field execution
  • Off-contract behavior went unnoticed until invoicing

The procurement strategy was strong — but jobsite-level compliance and execution were inconsistent.

4. Idle Time & Overlapping Rentals

Without centralized orchestration:

  • Equipment overlapped unnecessarily between phases
  • Assets remained on rent longer than needed
  • Utilization patterns were inconsistent
  • Invoice corrections were frequent

The issue wasn’t negotiated rates — it was execution variance.

The SiteStack Solution

SiteStack evaluated the contractor’s historical rental activity across:

  • jobsite coordinates
  • supplier proximity and response times
  • hauling distances and cost impact
  • utilization and idle patterns
  • consistency of supplier selection
  • off-contract behavior
  • workflow inefficiencies between teams and regions
  • discrepancies between the procurement system’s approved vendors and what actually happened in the field

The analysis made one thing obvious:

The cost problem had nothing to do with rates.

It was caused by inconsistent supplier selection and hauling logistics.

 

 

✓ Intelligent Vendor Optimization

SiteStack applied location-based logic to standardize supplier selection by:

  • Jobsite proximity
  • Hauling/mobilization impact
  • Rate-card alignment
  • Historical performance
  • Availability

This aligned field decisions with procurement strategy automatically.

✓ Logistics-Driven Cost Modeling

By simulating supplier proximity and haul-distance impact across the entire rental portfolio, SiteStack identified:

  • Regions overpaying due to distance
  • Non-preferred vendor usage patterns
  • Overlapping rentals
  • Off-contract charges
  • Execution inconsistencies between teams

✓ Enterprise-Level Visibility Across Programs

Leadership gained a consolidated, data-driven view of:

  • Regional execution variance
  • True delivered cost vs. negotiated rate
  • Logistics inefficiencies
  • Supplier performance
  • Annualized savings opportunity

 

The Impact

Across $20M+ in annual rental spend, SiteStack identified:

➡ 20% Savings Opportunity

Approximately $4M in annual savings, driven by:

  • Consistent preferred vendor usage
  • Reduced hauling and mobilization distance
  • Elimination of overlapping rentals
  • Tighter on/off-rent discipline
  • Fewer invoice corrections and off-contract charges

➡ Standardized Field Execution Across All Regions

SiteStack aligned jobsite behavior with procurement strategy by:

  • Removing supplier guesswork
  • Enforcing proximity-based selection logic
  • Reducing regional variability
  • Ensuring rate-card compliance at the booking level

Every project followed the same cost-optimized workflow — regardless of geography.

➡ Enterprise Visibility Into True Delivered Cost

Leadership gained a unified view of:

  • Regional cost variance
  • Logistics-driven spend drivers
  • Vendor performance trends
  • Idle equipment exposure
  • Program-level savings opportunities

What was previously hidden inside field-level decisions became measurable, controllable, and predictable.
