Callum assisted Clough in closing out the construction of a new naval base in Papua New Guinea on behalf of the Australian Defence Force. As key project personnel transitioned off the project, Clough engaged IAG to provide additional support. Callum quickly established relationships with Clough representatives and external stakeholders to gain institutional knowledge of the project’s history and contractual obligations. He identified outstanding operational and documentation requirements, developed a structured approach to address them, and implemented processes to track and verify completion activities. His ability to navigate complex stakeholder dynamics and resolve outstanding issues was critical in achieving contractual closeout objectives.

Callum supported bp pulse in developing a deployment strategy for public EV chargers across the United States, leading to grant applications in over 20 states under the National Electric Vehicle Infrastructure (NEVI) program. The program imposed complex commercial and contractual requirements for funding eligibility. Callum developed deep expertise in these requirements and translated them into actionable guidance for the client. He engaged with diverse stakeholders—including bp pulse, technical advisors, landowners, charge point manufacturers, energy providers, and maintenance providers—to identify and resolve potential compliance challenges, ensuring all requirements were met ahead of submission deadlines.

Callum supported the development of the Policy and Procedures Manual for Delta Air Lines’ $5.8 billion AUD terminal redevelopment at LaGuardia Airport, New York. His role involved auditing existing project controls to ensure alignment with key commercial terms and industry best practices, enhancing governance and project outcomes. As part of this effort, Callum conducted an internal audit of closeout processes, reviewing contractual obligations for both the general contractor and subcontractors. He engaged extensively with project management personnel to assess how closeout procedures were implemented in practice versus documented requirements. Where discrepancies or inefficiencies were identified—particularly delays in critical closeout steps—he conducted root cause analysis and proposed process improvements to streamline completion.
