Mark Baker: Repositioning BESIX Watpac for a New Era of Complex Construction
Mark Baker’s leadership story is not a founder story in the usual sense, but it has many of the same ingredients: a deep institutional understanding of a company, a period of transition, and the task of rebuilding momentum around a sharper identity. BESIX Watpac identifies Baker as its Chief Executive Officer, noting that he has been with the company for more than 15 years and has more than 25 years’ experience across business operations, strategy, finance and corporate governance.
That background matters because Baker’s current role is inseparable from the transformation of Watpac into BESIX Watpac. He joined the company in 2010 and served for a decade as Chief Financial Officer, before being appointed CEO in late 2021 after the company had moved through its integration with Belgium’s BESIX Group. The company’s own 40-year history materials describe this period as the completion of its transition into a fully merged BESIX Group entity, with Baker appointed to build the next phase around operational excellence, complex projects and people development.
In the current role, Baker’s major impact has been to move BESIX Watpac from transition into renewed competitive strength. The company’s 2024 annual review described 2024 as a pivotal turning point, with strategic groundwork from prior years beginning to show in improved financial performance. The company then reported a record order book of $3.5 billion and described the year as one in which its refreshed strategy and project selection had translated into a stronger market position.
That is an important distinction in construction leadership. Growth in construction can be dangerous if it is driven by volume alone. Baker’s profile is stronger because his public comments and company materials consistently emphasise selected work, complex capability and disciplined delivery. In other words, the achievement is not just that BESIX Watpac won more work; it is that the company appears to have repositioned around projects where its engineering, design and delivery capability can add value.
The market evidence supports that repositioning. BESIX Watpac was reported as leading Australia’s construction sector in new project starts for 2024, with $3.45 billion in new project starts in BCI Central’s Construction League rankings. That is a striking outcome for a business that had spent the preceding years recalibrating its strategy and integrating its identity inside a global construction group.
Baker’s current impact is also visible through the types of projects BESIX Watpac has been winning and delivering. In 2024 and 2025, the company pointed to major work across sectors including health and sciences, secure facilities, complex industrial, stadiums, bridges and precinct development. Its recent pipeline has included the Moore Park Precinct Village project in Sydney, the CSL Seqirus Project Banksia biopharmaceutical facility in Melbourne, the Te Kaha stadium project in Christchurch, and defence-related infrastructure such as the $200 million Defence Maintenance and Modification Facility in South Australia.
Those projects show the strategic logic of Baker’s leadership. BESIX Watpac is not presenting itself as a generic builder. It is leaning into technically demanding work where design, engineering solutions, stakeholder management and construction delivery all matter. In a sector where margins can be fragile and risk allocation can be punishing, that positioning is significant. Baker’s finance and governance background likely matters here; he came into the CEO role with a strong understanding of risk, cost and contract discipline.
His earlier career inside the company helps explain why he was well suited to that challenge. As CFO and Company Secretary from 2011, Baker would have seen the business through multiple phases: Watpac’s life as a listed contractor, BESIX’s increasing ownership, the delisting and acquisition process, and the later rebranding as BESIX Watpac. He was therefore not just inheriting a construction business; he had helped manage the financial and governance architecture behind its transformation.
That past experience is not resume filler. It is central to understanding the kind of CEO Baker has become. Some construction leaders are primarily project leaders. Others are rainmakers. Baker’s differentiator is that he combines construction-sector experience with a strong corporate finance and governance foundation. That has likely helped him lead through the harder work of reshaping the company’s operating model, selecting projects more carefully and stabilising performance after a challenging market cycle.
Recognition has followed. In 2025, BESIX Watpac announced that Baker had won consecutive leadership awards, including Executive of the Year for Construction, Transport and Logistics at The CEO Magazine’s Executive of the Year Awards and The Urban Developer’s Urban Leader Award for Construction. The company framed those awards around his people-first leadership, company growth and focus on smarter delivery, productivity, digital construction, safety and partnerships.
