Relocation project management
We support office relocations by leveraging our specialized expertise, creating environments that enhance productivity.
In addition to brokerage services, we provide comprehensive support for every stage of the relocation process—including efficient office planning, cost-conscious strategies for both initial setup and long-term maintenance, layout design, budget review, construction coordination, and move-in scheduling.
Our solutions are tailored to each client’s vision, helping to create office spaces that empower employees and maximize workplace performance.
Project management services
Achieving efficient and seamless operations through consistent project management.
Construction management（CM）
We oversee the entire project in close collaboration with the client, ensuring a highly transparent and cost-effective construction process.
Each phase of the construction is individually contracted, with our company assuming overall project management. A dedicated Construction Manager (CMr) works alongside the client to oversee the full project lifecycle.
Compared to traditional lump-sum contracting, this approach provides enhanced transparency and greater cost efficiency.
