Project Overview

BioGeo was engaged by a Queensland Government water utility across three separate projects to optimise the logistical deployment of their sampling and servicing teams — reducing costs, saving time, and mitigating driving-related safety risks for field staff.

What We Did

• Collated and structured operational data including sampling locations, servicing schedules, resource hub locations, and operational constraints as a baseline for identifying logistical inefficiencies

• Applied geospatial network analysis algorithms to solve the travelling salesman problem — identifying optimal multi-stop routes across a large operational network

• Modelled alternative deployment routes conforming to real operational constraints including maximum field time, workday duration, and team configurations

• Produced actionable route recommendations with projected time, distance, and cost savings for each scenario

• Updated and refined the model across subsequent engagements as the network, operational requirements, and resource configurations evolved

Outcome

The optimised routes delivered an annual reduction of tens of thousands of kilometres driven — translating directly into measurable cost savings and a material reduction in driving-related safety risk for field staff. Three repeat engagements over six years reflect the sustained operational value of the approach. The client can be offered as a project reference.
