What is suggested by the phrase "separate contract from architectural services"?

The phrase "separate contract from architectural services" implies that there is a distinction between the architectural services provided and other services, such as engineering design. This suggests that the client retains the option to engage independent firms for engineering design rather than relying solely on the architectural firm. By doing so, the client can ensure that they are getting specialized expertise tailored to their specific needs in engineering, independent from the overarching architectural contract. This separation allows for more flexibility in selecting qualified professionals for different aspects of a project, ultimately aiming for a comprehensive and well-coordinated design and construction process.
