About the work

Why the work is being done
Digital Services at the Border (DSAB) requires a inter domain gateway for validation of information across a security boundary. The inter domain gateway has been procured with the first release is due to be delivered on 5th December 2016.

The Home Office has requirement that the inter domain gateway undergo a CESG Tailored Assurance Service (CTAS) Evaluation. This must be completed before the end of February 2017.
Problem to be solved
The Home Office require this level of assurance that the security controls in place for the inter domain gateway mitigate any potential risks.

Without this assurance the new DSAB platform will not Go Live until CTAS accreditation is successfully completed.
Who the users are and what they need to do
A Border Force officer (user) is required to perform detailed checks for incoming and outgoing individuals at the Border.

The CTAS Evaluation needs to perform a detailed assessment of the inter domain gateway so that any risks associated with the new solution have been identified before Go Live.

Questions asked by suppliers

1. .
The dates for the two Q&A workshops have been revised to allow time for suppliers to respond before the first session, which is now Tuesday 29 November.

DSAB will hold two (2) workshops for interested suppliers on;- - Tuesday 29 November at 10 Great George Street, London SW1P 3AE (13.00 to 14.30) and – Thursday 1 December at 10 Great George Street, London, SW1P 3AE (13.00 to 14.30)
Please contact the to confirm attendance - (1 per supplier)
2. What is the schedule for Award, CTASEvaluation workshops and Testing?
It is anticipated that Award notification will take place on Monday 12 December or Tuesday 13 December at the latest and not 5 December as shown in the notice.

CTAS Evaluation workshops will be held between Friday 16th and Monday 19th December.

Testing will commence Monday 19th December and is scheduled to continue up to Friday 23 December 2016
3. Please can we clarify the timeline detailed in the clarification response above? The deadline for expressing interest in the 8 December, and the award notification specified as the 12/13th Dec. Our understanding is suppliers have two weeks to express interest, after which the Buying Authority may need to conduct a shortlisting exercise if too many suppliers register interest, where suppliers provide evidence of their 'essential' and 'nice-to-have' skills and experience. CCS indicate a minimum of 5 days must be given to respond. Then the 3 shortlisted suppliers complete the proposal submission stage, after which the contract is awarded.
Our understanding is that the additional period described following the shortlisting exercise to provide a proposal is an 'optional' step and we are not proposing to use it for this procurement, due to the time constraints around this particular piece of work.

The workshops that are being held on Tuesday 29th November and Thursday 1 November should provide additional details required to inform any proposals that are to be submitted for consideration regarding this requirement.

Confirmation of clearance will be required to attend the Q&A workshops on Tuesday and Thursday and should be brought with all attendees.
4. Given you want to award the contract by the 12th December, what will the next steps be between the 8th December close date and contract award? Given the short timeframe, please can you tell us how many words will you ask for in the shortlisting questionnaire if you get more than 3 suppliers who tick all boxes. Will you be using the 2000 word template for proposal response?
We are proposing to evaluate using the Proposal Template with the 2000 word limit but would suggest that any relevant information not in the proposal is attached.

Please note; - our expectation is that any Proposal documents will be submitted on 8th December along with the shortlisting questionnaire and evaluated at that time. Additional time will not be available to submit a proposal after 8th December. This is due to the time constraints around this particular piece of work.
5. Are there any restrictions on who may attend the Q&A Workshops on Tuesday 29th November and Thursday 1 December?
There is a need for all individuals attending the Q&A Workshops to hold SC clearance due to the nature of the CTAS evaluation. Confirmation of clearance held will need to be provided on the day.
