London Central Build Blog – Week 61 & 62

This next period of work has seen the cooling system reach completion, and final works start on the data hall side of the power commissioning.

London Central Build Blog – Week 56 to 60

Major advancements have been made this week on the generator and UPS systems, which brings us ever closer to having clients online at the new facility.

The past few weeks have been spent finalising the electrical intake room, which has allowed us to commission most of the power-side systems (generators etc), as well as re-energising the facility in its final state, ready for initial occupation. As such, our office has been offline, which has meant no updates to the blog (other administrative jobs took precedent while under limited access).

This post contains a large number of images from works undertaken over the past 3/4 weeks.

From here on out, updates will be less based on weeks, and more on tasks, as we push to get the site ready for initial occupancy.

London Central Build Blog – Week 55

This week has seen works under way in the electrical intake room, as well as other power-related areas throughout the site.

Much progress has been made again this week, with a vast amount of the remaining cable pulls completed ready for extensive commissioning over the next few weeks.

As you can see, we are now very much in the final phase of the project, with primary focus in the coming weeks placed on the electrical intake room, which will allow us to bring the site online.

London Central Build Blog – Week 53

Cabling continues this week, along with completion of final routes around the facility for cable runs. Our Emergency Power Off (EPO) system also took shape this week, which is an added safety feature that will allow the site to be blacked out should there be any major issues requiring a total power off (fire, electric shock etc).
