In plain English
Royal Botanic Gardens, Kew is looking for a principal contractor to conserve, refurbish and improve accessibility at the Grade I listed Palm House, which sits within the UNESCO World Heritage Site at Kew. The work covers the historic building's structure, glazing, ironwork, ventilation, stonework, rainwater goods and building services, all carried out while the gardens stay operational. Separate decarbonisation and landscaping contracts are excluded.
What the buyer wants
• Act as principal contractor to deliver conservation, refurbishment and accessibility works to the Palm House. • Carry out glazing replacement, wrought and cast ironwork conservation, ventilation system overhaul, stonework and dado repairs, rainwater goods restoration, internal alterations, M&E works and related enabling works. • Coordinate all works around site visitors, staff, living collections and ongoing garden operations and maintenance.
Requirements
What could rule a small business out: At an estimated £20 million, with a principal contractor role covering a Grade I listed building inside a UNESCO site and a live operational environment, this is most likely to rule out small businesses, as the scale and the need to lead a multi-discipline package would normally exceed what a small firm can take on alone.
Always check the tender documents.
