Mobile Subscription Services for U.S. Embassy Singapore

RFP 19SN1026R0005 seeks proposals for commercial mobile telephone services for the U.S. Embassy in Singapore. This indefinite-delivery, indefinite-quantity (IDIQ) contract will provide mobile voice, data, SMS, and international roaming/direct dialing services for approximately 300 lines over a one-year base period and one one-year option. Key requirements include continuous service, technical controls for roaming and IDD, direct contractor control over the network, and compliance with Singaporean regulations. Pricing will be in Singapore Dollars, with a 9% Goods and Services Tax (GST) charged separately. The contract has a minimum guarantee of SGD 4,000.00 and a maximum ceiling of SGD 400,000.00. Offerors must submit separate pricing and technical proposals, including a Cybersecurity Supply Chain Risk Management (C-SCRM) Questionnaire, detailed service plans, and proof of local licensing and SAM registration.

The Cybersecurity Supply Chain Risk Management (C-SCRM) Questionnaire is a document designed for vendors to assess and report their cybersecurity supply chain risk management practices. It is divided into three sections: Contact Information, Vendor Risk Management Plan, and Physical and Personnel Security. Vendors are required to provide details such as company name, primary point-of-contact information, and responses to questions concerning their organization's identification of supply chain threats, mapping of key suppliers, SCRM requirements in contracts, and verification of supplier compliance. Additionally, it addresses policies for background checks, literacy training on insider threat recognition, and procedures to prevent tampering of Information and Communications Technology (ICT) equipment. The questionnaire emphasizes compliance with NIST SP 800-53 references and instructs vendors to complete all items in the gray shaded lines, with the government reserving the right to request validating documentation.
