Provision of DDI Hand Held Xray and Tripod

This Request for Information (RFI) is hereby being issued in relation to an upcoming Requirement. The aim is to seek information about where the market stands in order to better refine our requirement.

Approximate Contract Value: £13,000 (inclusive of all non-recoverable VAT) Contract Duration: 3+1+1 This contract is below threshold for Public Contract Regulations (PCR) 2015.

1. OPPORTUNITY DETAILS

1.1 The requirement will be issued by Defence Medical Services (DMS), Ministry of Defence.

1.2 The role of the Defence Dental Identification team is to identify fallen Service personnel through forensic dental examination in the field. Without the use of dental digital radiography post-mortem to compare with ante mortem dental images, a positive identification is much less likely to be established.

1.3 Dental radiography is routinely used in forensic dentistry and considered to be an essential part of the identification process, owing to the visual, comparable nature of the Post-mortem and Ante Mortem images.

2. REQUIREMENT OVERVIEW

2.1 The purchase of 2 x handheld x-ray units and tripods is required to ensure the continuous provision of forensic dental examination for the identification of deceased military personnel.

2.2 The tripods comply with Local Radiation Protection Rules in that they allow the operators to stand a controlled distance of 1.5m away from the x-ray tube and patient, and not in the primary beam.

2.3 The system is to be used for routine intra-oral dental direct radiography, compatible with current digital and conventional film systems. The system must be compatible with the current DEXIS™ sensor and DEXIS™ software on the Toughbook laptop and future Digital Defence Imaging (DDI) digital sensor and image capture software.

2.4 The system must have a rechargeable battery to provide 8-10 hours of use per charge and must have battery charging housing

2.5 The system must have a robust protective case for transportation (including aircraft) and to protect against damage.

3. QUALITY STANDARDS

3.1 The Contractor must ensure the system is CE marked to comply with all EU and UK current safety guidelines.

4. AUTHORITY QUESTIONS TO SUPPLIERS

1. Please describe the type of warranty that comes with the product.

2. Do you offer servicing and repair packages? If so, please outline the options available. What payment structure would you use?

3. Do you think the proposed budget is realistic for the requirement?

4. Please provide any further information, issues or benefits that you could consider relevant in refining the requirement.

Your response is required by 28th March 2022 and will be treated with confidentiality. Answers will not be shared with any of the other supplier.
