Collaborative logistics planning between suppliers and contractors is essential in the construction industry—especially when on-time deliveries directly impact project timelines, labor scheduling, and job site safety. To make this collaboration successful, you need more than good intentions—you need data-backed visibility.
Tracking the right key performance indicators (KPIs) helps you measure the effectiveness of your logistics strategy, identify bottlenecks, and continuously improve how you work with contractors.
Here are the most important KPIs to monitor for effective collaborative logistics planning with contractors.
- On-Time Delivery Rate (OTD)
What it Measures:
The percentage of deliveries that arrive within the contractor’s expected time window.
Why It Matters:
Construction sites operate on tight schedules. A late or early delivery can disrupt workflow, cause idle labor, or delay other trades.
How to Use It:
Segment by contractor, job site, and product type
Track trends by week, region, or delivery team
Set shared goals with contractors to improve reliability
- First-Attempt Delivery Success Rate
What it Measures:
The percentage of deliveries successfully completed on the first attempt without rescheduling or rejection.
Why It Matters:
Failed delivery attempts waste time, labor, and increase the risk of return logistics or material damage.
How to Use It:
Analyze failed attempts by cause (site access, timing, documentation)
Create site-specific delivery profiles to improve readiness
Use this KPI in contractor planning meetings
- Delivery Window Accuracy
What it Measures:
The precision with which deliveries meet the agreed delivery window—not just by day, but by hour or shift.
Why It Matters:
Contractors often align material delivery with labor crews and equipment schedules. Tight window accuracy reduces waste and improves job site flow.
How to Use It:
Set delivery windows with each job site
Monitor deviation frequency and causes
Use this KPI to fine-tune dispatch planning
- Contractor Communication Response Time
What it Measures:
Average time taken to respond to contractor delivery updates, questions, or changes.
Why It Matters:
Effective logistics is as much about communication as transportation. Fast, clear coordination reduces last-minute surprises.
How to Use It:
Monitor time to first response for contractor inquiries
Set internal SLAs for contractor communication
Use it to train dispatch and customer service teams
- Delivery Documentation Accuracy (POD Compliance)
What it Measures:
The percentage of deliveries with correct, complete, and verified Proof of Delivery (POD), including signatures, photos, or time stamps.
Why It Matters:
Accurate documentation supports invoicing, reduces disputes, and protects both supplier and contractor in the case of claims.
How to Use It:
Integrate mobile POD capture tools
Require standardized documentation from drivers or 3PLs
Track documentation errors and correct process gaps
- Job Site Feedback Score
What it Measures:
A rating or score collected directly from job site supervisors after each delivery (or periodically during the project).
Why It Matters:
It gives you direct insight into how contractors view your delivery performance—beyond internal logistics KPIs.
How to Use It:
Use short mobile surveys or QR codes for real-time feedback
Monitor trends by job site or delivery crew
Close the loop on negative feedback with process improvements
- Planned vs. Actual Delivery Variance
What it Measures:
The difference between planned delivery date/time and actual execution.
Why It Matters:
This KPI shows how well your planning aligns with reality—and reveals the impact of weather, labor, or supply chain disruptions.
How to Use It:
Calculate variance in hours or days
Identify consistent patterns of drift
Adjust planning models and contractor expectations accordingly
- Logistics Exception Rate
What it Measures:
The percentage of deliveries with exceptions such as reroutes, missed appointments, or incorrect deliveries.
Why It Matters:
A high exception rate indicates process instability, which directly affects contractor satisfaction and job site productivity.
How to Use It:
Classify exceptions by type and source
Develop SOPs for common disruptions
Set benchmarks for improvement
- Material Handling Time at Job Sites
What it Measures:
Average time to unload and stage materials once a delivery reaches the job site.
Why It Matters:
Slow offloading leads to delivery bottlenecks, truck idle time, and inefficient labor use at the site.
How to Use It:
Track by material type or contractor
Provide site-specific offload instructions
Optimize staging procedures in collaboration with site managers
Final Thoughts
Collaborative logistics planning only works when both parties have visibility into performance—and when there’s a shared commitment to continuous improvement. By tracking the KPIs above, you can uncover inefficiencies, build stronger contractor relationships, and create a logistics process that supports—not slows down—construction.
The contractors you serve don’t just want materials delivered—they want delivery that’s predictable, flexible, and aligned with how they work. Monitoring the right KPIs gets you there.
