A Feasibility Study has just been completed both for base build and fit-out leading to the identification of a set of recommended options for the base build and a set of design principles for the fit-out. The base build works for all the galleries in scope will encompass design and works for (high-level scope, including but not limited to): - Conservation of the gallery spaces - Making good of the fabric of the building - New ventilation and heating / cooling system and associated Building Works in Connection (BWIC) - Mechanical, electrical and public health systems - Creation of new plant rooms to support the increased needs of the spaces - Required structural works Additional works (including but not limited to): - clearance of existing spaces - Dismantling and removal of Dinosaur Gallery walkway - Decant and recant of Botany Library contents - Temporary relocation of Dino Shop - Decant and relocation of offices to make room for the new circulation core - Relocation and enlargement of ground floor café - Conservation of existing fixtures and finishes (e.g. cabinets and bookcases) in Old General Herbarium and Botany Library - Removal of existing Dino shop and dog leg corridor in the Swing Space - Creation of 2 new vertical circulation cores (lifts and staircase) - Decant and relocation of offices to make room for the new circulation core - Creation of new toilets and ancillary spaces - Relocation and enlargement of ground floor café - Creation of new café on the first floor - Fit out of new Dino Shop and the two cafes. The appointed consultants will be asked to act as Lead Architect, developing the base build design for the galleries and ancillary spaces across RIBA stages 2-7, supervising and coordinating the works of the other base build consultants, such as, but not limited to, MEP consultants, circulation consultants, accessibility consultant and fire consultant and coordinating the fit-out consultants to ensure continuity between the projects.
