## Construction & Field Service: Mileage Best Practices

Construction and field service professionals have unique travel patterns requiring specific approach to mileage.

## Sector Characteristics

- Multiple job sites same day
- Transport of heavy equipment and tools (increases consumption)
- Trips to suppliers for materials
- Emergencies and urgent calls outside hours
- Larger vehicles (vans, pickups) with higher cost/km

BEST PRACTICES:

1.[^irs-pub463] CATEGORIZATION:
   - Main trip: home → site → home
   - Secondary trip: site → supplier → site
   - Emergency: additional outside business hours
   Separate for analysis and potentially different rates

2. VEHICLES:
   - Vans/pickups have 40-60% higher real cost than cars
   - Consider differentiated rate by vehicle type
   - Document cargo capacity as justification

3. DOCUMENTATION:
   - Odometer photo start/end of day
   - Invoice of materials purchased as proof of supplier trip
   - Urgent call record to justify extra trip

4. ROUTE OPTIMIZATION:
   - Plan material purchases to consolidate trips
   - Use routing apps to sequence multiple sites
   - Consider central depot vs direct site delivery

5. TOOLS:
   - Industrial GPS resistant to dust/water
   - Apps working offline (remote sites without signal)
   - Integration with work order system

## Real Case

Self-employed electrician drove 300km/day visiting 4-5 sites. Using routing app + Quilometragem, reduced to 220km maintaining same productivity. 25% savings + longer vehicle life.

## Frequently asked questions

### How to handle multi-site days?

Log each between-site leg as a separate trip linked to the contract or work order of the corresponding site.

### Should the rate be higher for vans and pickups?

Yes. Real cost for these vehicles is 40–60% higher than passenger cars and policy should reflect that difference to be fair.

### How to document emergency calls?

Keep the call record (ticket system, client message) attached to the trip to justify after-hours travel.
