This project is anticipated to run across 2-3 years, separated into the following phases:

Phase 1 (in FY26/27) - to survey the existing PAVA system with appraisals provided, prepare design and specifications for works tender and programmes in phases from design till commissioning, (RIBA 1 -4).

Phase 2 (in FY27/28 & FY28/29) – to provide expertise support in reviewing Contractor’s deliverables and work done on site, testing and commissioning support, operation readiness till handover to the Estates Operations/ BAU, (RIBA 5-7).

The Museum will soon be undertaking an open tender exercise to procure the services of a Lead Design Consultant for this project. The scope of works for the Lead Design Consultant is as follows:

-The Consultant shall act as the Client’s independent technical advisor, responsible for survey, design, specification, and management of the works throughout the project cycle from design to installation stages. (RIBA 1-5)

-The Consultant shall provide testing, commissioning, and handover support to ensure operational readiness over 2-3 years programme. (RIBA 6-7)

-The Consultant shall take BSA Principal Designer Role which can either be in house or sub-contracted to the Lead Designer, throughout the project cycle.

Other considerations affecting this project include:

-The Museum is undertaking the NHM150 Programme that involved the refurbishment and reopening of spaces to the Public, these works are likely to take longer than the PAVA project and we need to ensure the new system is designed and installed to take on board these changes and should be prioritised in the Phasing.

-The Museum would also like to explore if there is any compliance requirement or best practice in regard to PAVA systems in external areas such as roofs of the buildings and gardens across the SK site.

The approximate budget for the full scope of works is approximately £200k. However, please be aware that only the RIBA 1-4 services for Phase 1 (in FY26/27) is guaranteed while the RIBA 5-7 services are subject to the phase programme to be provided by the design consultant and also the budgets in the following years, but still that required to be costed and evaluated for the purposes of this tender.
