Tate Galleries - Principal Contractor - Tate Britain Garden
Authority: Tate (Central government)·On behalf of: WARD WILLIAMS ASSOCIATES LLP
What is being bought
Published requirement descriptionTate Britain is creating a bold new garden for London in collaboration with celebrated garden designer Tom Stuart-Smith and the Royal Horticultural Society. Generously funded by the Clore Duffield Foundation, the Clore Garden will transform Tate Britain's exterior and offer beautiful natural spaces for residents, students and visitors to enjoy.
The Clore Garden will:
- transform Tate Britain's landscape, enhancing existing architecture and restoring sightlines
- amplify biodiversity through diverse planting, and improve sustainability
- create space to enjoy art outside the gallery, with works shared from Tate's collection
- feature a new café terrace with room for outdoor programmes, talks and learning events
- include a new classroom for school groups and adult learners to connect art with nature (separate contract).
Complementing Tate Britain's classical architecture, the garden's organic design will invite discovery year-round. From magnolias and blossom in spring, to seed heads and evergreens in autumn and winter, there will be eye-catching plants to delight in across the seasons. The garden will be fully accessible with quiet spaces, seating and interactive water features. The project includes the removal of and creative refabrication of existing landscaping to create new fluid pathways through the garden.
The project includes a separate new purpose-built garden classroom which is subject to an interdependent but separate procurement exercise. The garden includes key features aimed at celebrating the beauty of nature, creating a space of amenity where artwork can be explored in a different context whilst simultaneously allowing areas of public enjoyment and education to take place concurrently. The garden project includes works to elevate and improve existing listed features such as gates and railings, works to improve legibility and access and, additionally, key areas of interaction through a bespoke water feature and pond. New services will be provided including a proposed irrigation borehole, a new irrigation system, pathway lighting and event power. Works subject to a Section 278 Order, include the revised front layby, kerb lines and associated drainage and utilities.
The contract will be let as a traditional contract under a JCT Standard Building Contract, with tenderers acting as the Principal Contractor. The tenderers will act as Principal Contactor as defined in the Construction Design Management Regulations 2015 which will include the role to oversee a directly appointed contractor the Garden Classroom.
