Design and Build Outdoor Learning and Play Experience

The next exciting phase of enhancing the visitor experience at The Sill: National Landscape Discovery Centre is to incorporate an interactive play-based outdoor learning experience in the grounds surrounding The Sill.  Northumberland National Park Authority are seeking a suitably qualified and experienced consultant/specialist to design, manage the planning approval process and build this outdoor learning and play experience.

This project brief outlines our requirements and the considerations for interested parties to submit tenders and proposals for the design, identification of the optimum location within the grounds and to describe the build and installation for this area.

The play-based outdoor learning experience must reflect the aims, ethos, design and interpretation of The Sill. The learning experience must also reflect Northumberland National Park and its special qualities.

Suppliers that would like to take part in this tender process are invited to “Express Interest” at https://in-tendhost.co.uk/nnpa  upon which they will be given access to the full tender documentation delivery through this e-tendering system.

When the tender documents have been made available involved suppliers will receive notification via email and the tender documents can be accessed from the “My Tenders” area of https://in-tendhost.co.uk/nnpa by selecting the “View Details” button of this project.

The deadline for submissions of the tender will be 12noon on the 31st January 2020.
