Coordinating close collaboration with all stakeholders to deliver this complex facility

The Off-Board Information Systems Centre (OBISC) is the first facility handed to the Commonwealth that supports the deployment of 72 new Joint Strike Fighter F-35A aircraft. Our Project Management team overcame several complexities in the construction to deliver a secure facility that facilitates through-life support for the platform.

Several post-design Defence policy changes led to procurement compression of several key trades. Working closely with the client, our team achieved all project objectives for the Commonwealth to occupy the facility and undertake their stand-up works.

Maintaining a secure facility throughout construction

To ensure that no issues arose, our team worked with the client and Commonwealth security advisors to ensure all aspects of the facility were controlled during construction.

Strict personnel and equipment access controls were implemented throughout the delivery due to the nature of the end use of the facility. The facility was accredited as a secure environment in coordination with the Commonwealth occupation of the facility.

Overcoming shifting objectives

Due to the secure nature of the project, Defence was required to change policy post design, which altered the project’s requirements.

To ensure that all Commonwealth objectives were met, we worked with the managing contractor to review sequencing and maintain progress across affected trades. Despite the changes to the project’s requirements, the facility met the client’s objectives and was occupied on time.
