Vast changes again this time, as the electrical works push on at pace both inside and outside of the new facility.
While visually the site now appears a little less finished than before, with masses of flooring taken up to accommodate the newly installed containment and cabling, from a more wholistic view point, things are pushing forwards in a big way at the moment.
The pace of work and progress on-site has certainly been turned up a gear, as multiple trades now work together on various aspects of the facility’s power systems, alongside work on other related areas to maintain solid progression throughout.
We have a lot of photos to present this time around, so rather than spending too much time on the introduction, we’ll let them do the talking.
Our LV boards have arrived with us, split across two deliveries due to their size
This first batch of boards shown here are destined for LV Room A
We were able to swing the boards right into the loading bay, ready for pre-staging ahead of them being rolled into their final position on their respective plinths
The first couple of sections of the board now coupled together in LV Room A
Here we can see into the gland plate enclosures, where the large armoured cables will soon enter the boards to feed the various breakers seen in the chambers above
Here is another view of LV Room A, with the UPS Boards now also in their final places opposite the main board
The size of these boards makes taking a photo of them tricky – getting them all in view is nearly impossible – a wide angle lens in on our shopping list!
A view from the door of LV Room A, looking towards the boards now full situated, coupled, levelled and locked off
This is the view down one of the risers, as the containment between floors begins to take shape, and specialist containment for fire cable routes is run in
A look at some of the containment in place to hold the ladder work under the floor
Here we see the floor starting to go back down in Data Hall 1, now that the whips are in place – more on that further down in this post
Another view of the floor back in place at the rear of Row A in Pod 1, with only the termination at the PDU end to go
Lots of inter-room pathways have been made for cable routes in the past few weeks
The largest cables will be cleated to the ground, with slotted channel now fixed to the ground along these routes to accommodate this
Here we see the slotted channel in place under the floor in the LV Rooms
The main containment runs out to the generators are also starting to take shape
Further progress has also been made outside the building, with the trenches dug for the ducting that will carry our HV feeds into our demise
The main run of trench to take the ductwork out to the roadside
Here’s a look at the poured transformer base, with the shutter forming fully removed
A look at some of the machinery on-site to undertake the ground work
The trench continues to the road, with steel plates in place to bridge the gap for access while the top remains open
Here we see some of the smaller drums of earth cabling for this phase of the project arriving to site
Here’s one of the larger drums of earth cable, clocking in at around 750kg
Some more of the earth cabling in storage, along with a large quantity of the ladder to be installed around the facility
A sizable delivery of the larger armoured cabling that will run between the LV rooms, and to the Data Halls
Some of these drums are around 2 metres in diameter, with the delivery clocking in at circa eight tonnes
Some more of the drums inside, awaiting their time to land on the large 10 tonne axels we have for pulling them in – each single length of cable can weigh as much as 300kg, and needs to be pulled in using special rollers
A view of the cabling as it is laid under the floor, between the LV Rooms
Much of the floor has come up to allow for the cabling to be routed, along with the temporary removal of the UPS boards
The cabling has been partly stripped here, and installed into the gland plate ready for eventual termination
This view shows the cables starting to be cleated together, which run the width of the building between the two LV Rooms – there are 15 more cables to join this first three
The first set of cables reaching LV Room B, which will interlink the two boards
This view further shows some of the underfloor containment, which is multi-layered in the LV Rooms (top layer removed here)
This is a view of the now completed cabinet-side whip cabling in Data Hall 1, which will feed each of the racks with diverse power
This room alone has eaten up over 2km of cabling, with well over 3,000 ties holding it all down to the tray
Data Hall 1 has been flood cabled with feeds for all eventual rack locations, including the currently vacant spots for Pod 2
Diverse cable routes always take pathways which reduce cross-over, in this instance only happening once, where A and B feeds need to move past each other as each pod is cross-fed – a cable bridge has been installed to handle this
As always, the devil is in the detail, and we’re very pleased with how the underfloor cabling has come together in Data Hall 1
A view down the length of Row B, with all commando sockets in place, and earth bonding for both the racks and the raised floor visible
The A and B feeds to each rack only converge at the rack itself, otherwise maintaining fully separated routes throughout
Keeping routes so strictly diverse in this way requires far more cabling and containment, which comes with a great deal of additional cost and labour, however it is vital for true client-facing A/B redundancy
As you can see, it’s been a busy few weeks on-site here at NLE.
Things are certainly ramping up as we move into the closing stages of the opening phase of the project, which will allow our first clients to install kit into Data Hall 1.
It’s certainly a rather intense time to be a part of the NLE project, as multiple trades push on with various aspects of the build in tandem, ultimately taking us towards the finish line at pace, and in line with expectations on our phase one launch.
For the time being, much of the same. Progress will continue on electrical over the coming weeks, and we will also be pushing ahead with other areas, including the various cooling systems throughout the facility.
