BES completes Weston Park Pharmacy and aseptic suite project

Date published: 11 September 2023

Rochdale-based BES, a specialist in the design and delivery of complex facilities for the pharmaceutical and healthcare sectors, has completed a £2.5m project to create a new pharmacy and aseptic suite at Weston Park Hospital for the Sheffield Teaching Hospitals NHS Foundation Trust.

Designed, engineered, and constructed by BES, the new facilities aim to futureproof the hospital’s drug preparation capabilities on-site, with an ATMP-classified environment that enables the production of regenerative medicine, personalised treatments, and the development of nanomedicines.

Working collaboratively with the client in the role of both principal designer and principal contractor, BES designed the project for delivery in two phases. This enabled the hospital’s existing pharmacy to continue operating on a business-as-usual basis until the new pharmacy was ready for use.

BES refurbished a redundant office area on the 6th floor of the hospital to create the new, high-specification Chemotherapy aseptic dispensing facility in phase 1. Following commissioning and validation of this facility, the hospital’s pharmacy team moved across from the former pharmacy, vacating that area to allow the phase 2 refurbishment of the former pharmacy as the new aseptic suite with sophisticated clinical trial (CT) and ATMP preparation facilities.

Working with the hospital’s user requirement specification (URS) and engaging with the hospital’s estates team and senior pharmacist, BES’s multidisciplinary team took the project concept design from RIBA Stage 2 to stage 4, delivering buildability and value engineering benefits. The company’s integrated design and construction capability meant that the need to maintain business-as-usual conditions and uninterrupted pharmacy services during the programme could be embedded in the design process, resulting in smoother project delivery.

BES designed the new facilities to HTM and cGMP pharmaceutical requirements, carrying out the design qualification validation process before work began on site. Design development for the project also involved consultation with the MHRA (Medicines and Healthcare Regulatory Authority) to ensure the design of the facility is compliant with regulatory requirements and ensure a smooth validation process. This resulted in further design improvements to the aseptic suite design to avoid any cross-contamination risk.

Jonathan Morton, the BES engineering director responsible for leading the project said: “This project leveraged our multidisciplinary approach to coordination of architectural design, building services engineering and construction, along with our collaborative approach to working with the client and end-user stakeholders.

“With responsibility for maintaining business as usual within the live hospital environment and for health and safety as principal designer and principal contractor, we considered the needs of clinicians, service users and patients as an integral part of the design and delivery process.

“The result is a facility that supports the hospital’s reputation for excellence in cancer treatment and creates a template for future gene therapy preparation facilities for other NHS Trusts.”
