Project Overview
To support expanding capabilities at the MedImmune Way campus, Heffron self-performed the mechanical scope on AstraZeneca’s Antibody Drug Conjugate (ADC) Laboratory expansion — a project that more than doubled the size of the existing ADC space and reorganized the layout for maximum operational efficiency.
The defining challenge was keeping the existing lab running uninterrupted for all but a single two-week shutdown, during which the new exhaust systems were tied into the existing exhaust and live operations were relocated into the newly expanded space. Heffron then renovated the original lab in place.
Heffron’s mechanical scope included a fully welded stainless steel exhaust duct system, twelve flow hoods, a self-contained vacuum system, lab gases, casework integration, and airlocks — all delivered with the precise sequencing required to protect active research throughout construction.
