Overview

Protecting timelines through disruption & pandemic delays.

The Columboola Solar Farm in Queensland spans 410 hectares and powers up to 75,000 homes annually using over 400,000 bifacial solar panels.

But behind the impressive energy stats was a logistical challenge: delivering compliant signage and accessories on time, despite global freight disruption from Covid-19 and unpredictable weather.

Identimark worked closely with the EPC, Sterling & Wilson, to synchronise shipments with key project milestones—ensuring zero downtime and meeting every delivery requirement.

Challenge

What needed to be solved.

The Columboola Solar Farm project required precision delivery of signage and cable accessories during one of the most unpredictable periods for global logistics. Freight issues caused by Covid-19 had the potential to stall the entire project. With contractor crews scheduled and weather delays already putting pressure on the timeline, Sterling & Wilson needed a supplier that could not only deliver under pressure, but adapt in real-time to shifting needs.

Key challenges included:

Freight delays: Covid-19 restrictions severely disrupted global logistics, delaying incoming materials.

Weather setbacks: Heavy weather conditions put pressure on already tight installation timelines.

Complex milestone alignment: Coordinating timely deliveries with contractor schedules required precision and flexibility to avoid downtime.

This project marked the latest in a series of successful collaborations between Identimark and Sterling & Wilson. Our team worked directly with project managers to prioritise urgent shipments, ensuring that critical install phases were never held up. Products were batched and shipped to match specific construction milestones, avoiding excess freight costs while maximising efficiency.

Thanks to smart coordination and field-tested products, the Columboola Solar Farm signage rollout was completed without delay. Sterling & Wilson’s trust in Identimark continues across multiple renewable energy projects - and for good reason.
