What is being bought
Published requirement descriptionTate Modern's Turbine Hall is one of London's most iconic artistic spaces, where anyone can come in, look around and encounter art. Since it opened in 2000, over 60 million people have experienced the Turbine Hall. We want visitors to feel that the Hall and Tate Modern are a welcoming space, where they can encounter surprising, exciting and accessible digital experiences that connect them to Tate and spark fun and amazement.
We want visitors walking through the Turbine Hall to encounter an easy, direct, playful way of being transported back in time and seeing some iconic Turbine Hall commissions, experiencing 360 / 180-degree recreations of past Turbine Hall commissions through mixed reality.
For those who remember the commissions this would spark a memory and sense of connection to Tate. For those who don't remember a commission, they would be surprised by what they see.
The experience goes beyond passive viewing by including the option of designing your own commission and seeing the Turbine Hall come alive with your own ideas.
Prototyping and Future Contract
This tender is for the design and delivery of the Tate Time Machine prototype. It is the first phase of this opportunity, and we want to be clear from the outset about how the two are connected.
The prototype is not an end in itself. It is what Tate will use to secure funding from our partners for the full rollout of the experience; this funding bid is currently estimated in the region of £150,000. The successful supplier will play a central role in that effort: the quality and credibility of what you build will directly shape whether the funding bid succeeds, and we will look to you to support it by providing material, technical insight and, where helpful, taking part in conversations with prospective funders.
If that funding is secured, Tate will award the full rollout to the awarded tenderers from this process as an option under this contract, without a further competition, subject to satisfactory completion of the prototype phase and agreement of Phase 2 pricing and terms. This is why the competition is evaluated based on the whole project rather than the prototype alone, and why we are asking you about scalability, extensibility and long-term maintenance: we are appointing a partner for the full experience, not a contractor for a single piece of work.
If the bid to our partners is unsuccessful, the contract will conclude at the end of the prototype phase, the option will not be exercised, and no further work will follow. Tate gives no guarantee or commitment that the rollout will proceed, and Tenderers should plan and price the prototype phase on the basis that it may be the entirety of the work awarded.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
