PROJECT OUTCOMES

The civil design was incomplete at commencement however due to UGL and Alinta’s delivery schedule BGC Contracting were instructed to mobilise. This provided challenges in keeping the workforce and schedule progressing whilst mitigating delays and down time as much as possible. Inevitably the schedule and scope of works grew as the design matured to completion. Due to BGC Contracting’s collaborative and flexible approach, EOTs were minimised.

Working in a confined facility with SIMOP’s between civil, electrical and mechanical contractors meant that accurate daily and weekly works planning was essential to ensure the safety and continuity of works for all stakeholders.

Irrespective of the challenges of the growing scope and tight program the project was delivered in accordance with the revised budgets and schedule, delivered safely with zero recordable incidents. Specific recognition was given to BGC Contracting from the Alinta Project Management team for the quality of works and the collaborative culture that was demonstrated across the entire project by all of the BGC Contracting site and leadership team.
