Document No: E4502-D002-B50 as noted in Earlier BCP. - Review with Merrick measurement of isolator dP during site visit. (Merrick readings were approximately 15 pa different to that of the isolator.) - Replace HEPA's in Isolator 4 with old HEPA's for wash test. After test re-install the clean HEPA's and recommission - Update of B50's fumigation software and test. (Defect FOC) - Investigate with Merrick and propose resolution of Chiller break-downs. - HAZOP18 Specify and agree with users a quick coupling system and hoses for the Isolator supply and extract connections. Agree with users number and length of hoses and supply these. Modify all flexible extract vent ducts to have male connections. Modify all flexible supply vent ducts to have female connections. Modify connection couplings on isolators to suit. Supply 12 extract hoses and 12 supply hoses. - HAZOP21 update drawing to show differential pressure indication across bag filter downstream of attenuator. - HAZOP33 Provide P&IDs showing all instrumentation and control signals for isolators and AHU/exhaust systems. The concern is that the current diagrams do not show sufficient information. - Update all O&M's and provide electronic copy in approved DEFR Read full description ## CPV classification Engineering works and construction works Source Contracts Finder (UK) [View official notice ](https://www.contractsfinder.service.gov.uk/notice/7a5dbfe8-a69d-44ac-ba60-a5810ae5a9fc) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
