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.

Under FIDIC 1999, Sub-Clause 2.5 [Employer's Claims] provides that the Employer is entitled to make claims against the Contractor, which may result in deductions from the Contract Price and from Interim Payment Certificates.
Option C is correct. Delay Damages (Sub-Clause 8.7) are a classic example of Employer's entitlement. If the Contractor fails to complete within the Time for Completion, the Employer is entitled to delay damages, which are typically deducted directly from payments due.
Option A is also correct. Under provisions relating to Nominated Subcontractors (Sub-Clause 5.4), if the Employer pays a nominated subcontractor directly (e.g., due to Contractor default), such payments may be recovered from the Contractor and deducted from the Contract Price via Sub-Clause 2.5.
Option B is incorrect because costs related to reviewing Contractor's Documents are generally part of the Engineer's duties and are not recoverable from the Contractor unless explicitly stated.
Option D is incorrect because the use of Employer's materials is typically accounted for within the contract pricing structure and not treated as a claim under Sub-Clause 2.5.
Thus, Sub-Clause 2.5 serves as a key mechanism for the Employer to recover amounts due through deductions, particularly in cases like delay damages and payments made on behalf of the Contractor.

Option A is correct: The initial programme must include the date for the Contractor's access to the Site.
Option D is correct: Key delivery dates for Plant and Materials are essential elements of the programme.
Option B relates to updated/revised programmes, not the initial programme.
Option C generally relates to remedial work and is part of revised or detailed programmes.

Under FIDIC Red Book 1999, price adjustments after the Time for Completion are based on the indices or prices applicable on the date 49 days before the expiry of the Time for Completion, not the current index. This prevents the Contractor from benefiting from price fluctuations after the contract period.
This clause ensures fairness by locking the price basis as of a fixed reference date, protecting the Employer from increased costs due to delays.

The key issue in this question is the allocation of design responsibility and the treatment of unforeseeable physical conditions (particularly relevant for underground works or inaccessible areas).
The Yellow Book 2017 is specifically designed for projects where the Contractor is responsible for both design and execution, while still maintaining a balanced risk allocation. Importantly, Sub-Clause 4.12
[Unforeseeable Physical Conditions] allows the Contractor to claim additional time and/or cost for conditions that could not reasonably have been foreseen. Therefore, for projects involving underground or uninspectable works, the Yellow Book is highly appropriate. Hence, Option A is correct.
The Silver Book 2017 (EPC/Turnkey) also places full responsibility for design and execution on the Contractor. However, it adopts a much stricter risk allocation: the Contractor generally bears the risk of unforeseen physical conditions. This makes it less suitable for projects with significant uncertainty-unless amendments are made. By modifying Sub-Clause 4.12 in the Particular Conditions to reallocate risk (e.g., allowing relief for unforeseeable conditions), the Silver Book can be adapted for such projects. Therefore, Option C is correct.
Option B (Red Book) is incorrect because design responsibility primarily lies with the Employer, not the Contractor.
Option D is incorrect because using the Silver Book without amendment would place excessive and potentially unmanageable risk on the Contractor in cases involving unknown subsurface conditions.
This reflects a core FIDIC principle: selecting the appropriate form depends heavily on risk allocation and the degree of uncertainty in site conditions.
