The key requirement in this scenario is certainty of cost and time, particularly because the Employer intends to secure financing from a financial institution. Lenders typically require a high degree of predictability regarding project completion date and final contract price.

The FIDIC Silver Book 2017 (EPC/Turnkey Contract) is specifically designed for such situations. Under this form, the Contractor assumes full responsibility for both design and construction, as well as a significant portion of project risks, including many that would otherwise remain with the Employer under other FIDIC forms. This results in a lump-sum, fixed-price contract with greater certainty in final cost and schedule.

In contrast, the Red Book allocates design responsibility to the Employer and allows for more variability due to remeasurement and variations, making cost less predictable. The Yellow Book, although design-build, still allows more balanced risk sharing and potential adjustments, which can reduce price certainty compared to the Silver Book.

From a contract management perspective, the Silver Book is commonly used for privately financed infrastructure or projects requiring strong lender confidence, as it minimizes Employer risk and enhances bankability.

Therefore, for a hospital project requiring financial backing and maximum certainty in cost and time, the Silver Book is the most appropriate choice.
