Imperial College and MRC Research LaboratoriesBurlington Danes
We provided inspection and test of new clinical facilities and medical research laboratories. Unfortunately the original installation fell short of the standards required and extensive remedial works resulted.
We also provided scheme design suggestions, planning and assistance for the rebuild of the fuel pumping and delivery systems for the standby diesel generators.
We planned and managed extensive black-site switching tests on the occupied buildings, resulting in significant changes to the SCADA system and proving the capabilities of the UPS and diesel generators. We wrote switching scheduals and trained the ICL and FM team in how to switch the building on their main panels and backup systems, as well as on how to monitor and manage the generators and panels via the SCADA system.
We also installed additional main feeders and automatic changeover switchgear, and provided upgrades to the earthing and bonding of Group 1 and Group 2 medical and imaging locations.
Telford Ice Rink and Soft Play
Following the failure of the original M&E contractor we were engaged to provide 100% third-party inspection and test, prepare a remedial plan and carry out certain remedial works.
We did this with the building live and operational, allowing business to continue as usual, ensuring the safety of the new electrical installation.
Impact Building Services LtdDesign Support
Impact are a high quality electrical contractor – for a number of years we have worked alongside them on Data Centre projects. Impact engage us from time to support their designers on calculations for difficult loads such as MRI scanners and medical imaging.
GlaxoSmithKline (GSK)Clinical Imaging CentreFaraday cage earth faults
GSK had problems with multiple earth paths on the Faraday cages of 2 MRI rooms. They were getting poor image quality from the scanner installed in one of the rooms. The other unoccupied MRI room had been half dismantled to try to find fortuitous earth paths.
We injected test currents into the cages and scanner earthing systems and tracked these currents around the cages using their fields. We were able to find fortuitous earth points to within ~20cm non-invasively. Small easily-repaired holes in the stud walls allowed the shorts to be removed and remedied.
Various barrier joints in the services and quench pipes had been badly insulated. Using large custom made current clamps we were easily able to identify and remedy these faulty insulated joints.
