When does the design phase of a golf course typically conclude?

The design phase of a golf course concludes with the completion of a full set of construction drawings. This stage is critical as it involves not just the initial concepts and layouts devised by the architect, but a comprehensive set of detailed plans that will guide the construction process. These drawings include specifications for the course's features, topography, drainage, irrigation, landscaping, and any required structures, all of which are essential for ensuring that the construction aligns with the designer's vision and meets regulatory requirements.

The other options represent important steps that occur during the planning and development process but do not define the conclusion of the design phase. The completion of the first draft marks only an initial stage of development. Site surveys provide essential data needed for the design but are part of the preparatory work rather than the finalization. Securing project financing, while crucial for moving forward, does not directly pertain to the completion of the design work itself. Thus, the full set of construction drawings signifies the full readiness to proceed with building the golf course, marking the true end of the design phase.
