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.

Internals of the generator-side control units reaching completion

Internals of the generator-side power distribution with earthing in place

Internals of the generator-side power distribution reaching completion

Custom control cable junction boxes for generators reaching completion

UPS battery modules containing their brand new cells fitted and on the data hall floor, ready to fill out to first 3 UPS’s

Legacy electrical systems being removed ahead of total re-distribution and commissioning

Intake room wall being re-clad ahead of fit-out, much alike the opposite wall which contains the generator control and distribution systems

First of our new main distribution panels fitted -which will be the B side – along with our custom monitoring system flanking either side

A look at the monitoring which runs either side of the main power distribution panels

A closer look at our power monitoring system, which will total 24 screens when completed on both A and B sides

New cable containment allows for multiple routes both in and out of the facility distribution cabinets

A look at the earthing bars in the intake room, ahead of completion

Progression as earthing in the facility runs back to the earthing bars here

Facility power distribution having the various breakers fitted

Progress shot as the facility distribution panels are wired

The completed facility power distribution panel (A side), which powers facility-wide systems such as lighting and sockets

The B-side main distribution panel fitted with its breakers, which feed the UPS systems on the data hall and at the core

Distribution panels for the facility-wide systems completed in the centre here, ahead of the A-side primary panel being installed

A-side distribution being installed, along with flanking monitoring columns

Containment basket fitted, ready to take large input power cables between cabinets

A look at additional cable containment and control above the primary distribution panels, and up the wall to reach the mains incomers

A look at cable runs being installed between the power distribution panels and the B-side of the mains fail-over system

Stage one cabling complete for power systems feeding first floor data hall

Mains output feeds on the B-side supply, which feed into the B-side throughout the site

A look at the inlets atop the generator control and distribution cabinets

A look at the internals of the B-side AMF panel, which has its termination in progress here

The completed internals of the B-side AMF panel

A look at the primary breakers for the generator supplies

The AMF panel control unit powered and ready for configuring

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.

Glands being fitted to the top of the main generator breaker cabinet

A look at some of the copper inside of the main generator breaker cabinet

Here we see the generator / backup supply side of the electrical intake room taking shape

London Central Build Blog – Week 54

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.

Meet me room Emergency Power Off (EPO) unit in place

Final assembly completed on our custom cooling control units in the meet me room, with new Honeywell cooling controllers

Delivery of further Suprema BioEntry Plus units arrived this week

Cabling on our custom cooling control units under way

Final cable runs wind their way through the building – this shows an access point inside of the staff lounge

Riser cover fitted to cable containment on first floor data hall, as final commissioning is completed on the primary VESDA unit

Cutting of gland holes in generator power and control termination cabinets in electrical intake room under way

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).
