Leo Lynch is the key mechanical contractor at Astellas Dublin, responsible for all small-to-medium mechanical installation projects on campus and managed by PM Group.

Go-to mechanical and process engineering partner for PM Group at Astellas Dublin. 

Leo Lynch has completed several HAZOP utility improvement projects including replacement of waste transfer lines, Ethanol, DMF, Toluene Flow meter Upgrade, P3 NaOH Replacement and N2 Purge system upgrade.  

Our team is currently engaged with PM Group and Astellas on a number of further HAZOP utility improvement projects including P2 HCl Line Replacement, P3 HCl addition project, Centrifuge improvement, Discharge Valve replacement, Tank Farm Outlet Automation, Tank Farm N2 Instrumentation and P3 Vacuum Pump replacement. 

The following projects are also in progress and due for completion in early 2024 - P2 Scrubber Replacement, P3 Glass Lined Vessel replacement, P3 Dryer removal, Air compressor replacement Vessel Bottom Outlet valves replacement, P3 Solvent filter replacement, P2 and P3 HVAC Upgrade, Brine Tank replacement.

Working 24/7 for 12 weeks, Leo Lynch helped Pfizer deliver a new flagship facility for the production of critical COVID-19 vaccination tablets. 

Exceptionally aggressive six-month fast-track project to support Pfizer in the fight against COVID-19

Project Lightspeed was a key project for Pfizer in the fight against COVID-19.  The facility produces COVID vaccination tablets, which can be stored at ambient temperatures for several weeks. Unlike injectable vaccines, they do not require specialist refrigeration.


“Lightspeed” was carried out as a fast-track project, with an exceptionally aggressive 6-month program. Construction ran 24/7 for a 12-week period. Leo Lynch worked with the design team early on to allow for installation of main piping runs. The facility was built as an extension of an existing cleanroom. This required detailed planning with production to ensure existing facility operations were not affected. The new cleanroom includes over 2,500 meters of process pipework in an existing plantroom. An external structure was built to house the dust collection equipment. Leo Lynch designed the project using BIM (LOD 400) with QAQC documentation located to our central EIDA platform.

Leo Lynch provided the coordination, supply, installation, testing and commissioning of all process, mechanical and HVAC services for a new OSD manufacturing suite.

Full services co-ordination for entire construction within a live pharma facility 

This project was carried out within a functioning pharma facility, spanning a clean room and live ATEX rated tank farm. It involved the construction of a Oral Solid Dose (OSD) manufacturing suite for Xeljanz production. It was built over 3 levels in the fallow spaces surrounding operational areas in Building 3C. Existing facilities included an operational cleanroom at ground floor level and plantroom on the top level with a functioning dust collector room. The new ground floor cleanroom includes powder charging and milling, blending, tablet compression, aqueous coating, solvent coating, coating solution prep, tablet drilling and printing rooms. The second floor included dust collection, purified water generation and mechanical plant rooms. Other areas were composed of Building 8, a solvent end of line abatement system and Area B6, an extension to the existing tank farm. Leo Lynch designed the project using BIM (LOD 400) with all of the QAQC documentation uploaded to our EIDA platform.

Leo Lynch delivered engineering solutions for a major secondary pharmaceutical plant expansion on a “live” process facility, including scheduled shutdowns to minimise impact on production and operations.

A large-scale and complex project, delivered in a live process facility.

This project for Pfizer Newbridge (formerly Wyeth Medical) was a major secondary pharmaceutical plant expansion on a live process facility. 

The facility included HVAC, process and Sprinkler Installations, a two-storey office and conference facility to accommodate 200+ personnel, five communication rooms serving full production and product cold storeroom facilities. The system consists of full AC with constant volume with re-heats. 

Leo Lynch took an active role in the overall design process from an early stage through early contractor involvement. The team developed the P&IDs, GAs, specifications and detailed designs including ISOs. This project was designed in 3D.
