Focus on the Build Blog this time around has been firmly on progress with cabling and containment, which continues to develop across the entire site.
A hefty quantity of the largest internal cabling is now all in place, totalling around 8 tonnes. This will now be terminated, along with a host of smaller internal cabling, while additional large external cabling is run in thereafter, as we head ever closer to energisation at London East.
Weekly overview
We’ll get straight into the photos again this time around, as we take a look at cabling and containment developments on-site at NLE.
Containment has now firmly breached into the exterior areas of the new site, with the runs to the four generators taking shape hereAnother view of the generator containment as it works its way around to the point of entry on each gen setA closer view of the twin ladder runs out to the generators, to account for the large quantity of cabling required to connect these units back to the main switchboards and controllersWhat look to be simple drops across to the generators actually required considerable effort, as solid concrete and brickwork edging had to be excavated to allow for the ladder to pass through to the required locationOn the other side of the front compound, the twin ladder runs to the transformer have started to be installedHere we see the supporting slotted channel being prepared for installation on this solid block wall, which will house the transformer cable runs as they pass into the buildingThe external skin of the building has been modified to allow cabling to enter and pass along this routeHere’s a view of the uncovered cable ladder which sits under the floor in the ground floor access corridorHere we seem a temporary blanking panel in place until the ladder is ready to pass through the building – additional tray is being run in to hold AC pipework for traditional systems that will support supplementary areas of the buildingThe transformer base is now ready for the installation of the GRP enclosure, and the transformer itselfThis is a view inside of LV Room B, as some of the large ~300kg inter-room cables are run in, which will link the LV boards for various functions / reasons – they are simply laid in loose at this point in timeThis is the drum of cabling for connecting out to the generators, which clocks in at 2.2 tonnesOne of the first drums to be emptied – this was a 1.8 tonne spool, which is now all run in under the floor between the LV rooms – this will be modified and become an outside table for clients to useAnother finished drum, slightly smaller this time, equating to around 1.2 tonnesA look into LV Room A, with the cabling being pulled into its trefoil cleats A view into the main LV Room cabling route as they enter LV Room B, showing the cleats as they hold the cables down to the floor mounted channelAnother view into LV Room B as the routes continue to take shape, and the tails are fed all the way into the boardsEarth cable being pulled into the floor, which again will interconnect the LV RoomsA view into LV Room A, as the earth cables are laid into position ahead of cleatingHere we see the earth cabling being pulled into its cleated arrangement, which brings this main route to its full stateA look down the main cable route between LV Rooms, showing the multiple trefoils and earthing bundles and they run between the two main boards
As you can see, the main focus here has been on continued progression with cabling and containment, which will continue into the next instalment of the Build Blog.
As always, other works have of course been underway, both in the development of London East, and elsewhere across our ever-growing operation, however we’re keeping this post concise and on topic.
What’s next?
As with the previous ‘what’s next?’ update, we’re looking at more of the same over the next few weeks. We have a vast amount of cabling and termination to undertake, which we hope to see nearing completion by the time we next post to the Build Blog.
We’ll also be moving onto further work on fire and VESDA systems, and will be moving ahead with commissioning on cooling systems, as well as continued work on power, such as the roll out of ‘small power infrastructure’ (supplementary building-wide power sockets for cleaning equipment etc).
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.
Weekly overview
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.

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.
What’s next?
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.
We have a very exciting instalment of the build blog this time around, as we see masses of containment and cabling begin to roll into position at London East, along with civil works for our HV mains incomers.
This is another major turning point in the development of the new facility, as we head ever closer to energising the site ready for client deployments.
Weekly overview
Massive change has begun in earnest this week, as masses of under floor containment begins to flow into Data Hall 1. This has been flood cabled, and the installation team will then move onto the main containment runs which allow for cabling between the upstairs data halls and the downstairs LV rooms.
We’ve also got major civils happening both on-site and in the local area, as our incomers make their way to us, along with our first dark fibre links.

As you can see, things are changing rapidly now that the main electrical works are underway. Next week, we’re expecting to see completion on the in-room work for Data Hall 1, meaning containment works will begin in the LV rooms, and all of the runs in between.
We’re now eagerly awaiting the arrival of the large LV switchboards, which will be an exciting development for us. It’s a part of the project that we’ve been excited to see take shape, and an area of enormous financial investment.
While the base of the transformer may appear to be a somewhat simple hole in the ground, and a straightforward concrete pour, in reality it’s anything but. The internal rebar structure has been welded on-site, and is bonded directly to very deep earthing rods to ensure safety during operation.
Once Data Hall 1 is phase one complete on commando cabling, our team will move in to complete some additional items, including M&E feeds for cooling, VESDA pipework, ODF installation for network and fibre, and other related containment and cabling pieces.
What else has been happening?
We’ve extended our reach in Telehouse through to North 2.
As part of a private client deployment, we’ve rolled out two new racks in North 2, and as part of this we’ve now got diverse 10Gbps feeds from our network delivered into the building, from our Supernode in North, and our core node in HEX / LD8.
We’re excited to see our network continue to grow, reaching new facilities as our transit proposition helps business grow their presence online.
What’s next?
We’ve really just got lots of the same coming up; containment and cabling for the most part, throughout the facility, as we head towards energisation.
This will include works on the HV and transformer side, and will lead onto various M&E works including cooling power, data, control, and further leading on from that, VESDA air sample pipework.
Another period of exciting change and development on-site at NLE, as we continue to move towards phase one completion and readiness for the first clients to enter Data Hall 1.
We’ve seen the most notable changes in cooling and electrical, with major physical advancements in both of these critical areas.
Weekly overview
This latest period of work most keenly focused on major adjustments to our roof, through the installation of seven custom exhaust cowls which form the atmospheric extraction loop for the evaporative cooling system in Data Hall 1.
Here we see six of the seven extraction roof cowls for Data Hall 1 installed on the roof of the building, over the cold corridorAnother view of the cowls from the roof, which allow for hot air to leave the building when not required as part of the recirculation loopThe view inside one of the cowls, which are the high velocity variant, given the amount of air each fan can move at full speed – visible here are the self-closing lids and the bird meshThis is the view inside the cold corridor, looking directly up at the custom containment frame which holds the fans and custom blanks – more fans will be added as required for each hallA wider view from inside – this view of the fans and frame will soon be hidden, as a sub-ceiling is to be installed here, to keep cold intake and hot extraction separatedA closer look at one of the extraction fans, with the fibre glass lids visible through the blades – we’re using Ziehl Abegg fans throughout, as deployed to great success at London Central (some of which have been spinning without any interruption since 2015!)Although we’ve already shown the newly completed loading dock setup in the warehouse, here is a wider view of the first floor assembly, to match that seen on the ground floorOur new master building fire panel is now in place, ahead of final commissioning – this new system is considerably larger and more feature-rich than the system it’s replacingA closer view of the new building fire panel, which interconnects with all detectors, beacons and sounders, along with the extinguishant panels and VESDA systems in each data hall / plant roomHere we see our custom designed plinths being fitted and levelled in one of the LV electrical rooms, which will soon take our main switchgearA view of the main switchgear plinths in the A-side LV room, now levelled and with the floor refinished to the new edgesThis is a view across the A-side LV room, also showing the smaller plinths in place to house the UPS switchgear for this spaceThis is the same view inside of the B-side LV roomA wider view from the B-side LV room, showing the scale of the main switchboards (the B-side board is ~7 metres long!)We’ve now begun preparing the main risers for cable ladder and other containment, which is set for installation next week ahead of flood cabling and commissioning the site throughout JuneHere we see one of our custom designed cableway enclosures, sat atop one of the newly installed plinths – our custom Mardix transfer boards then sit on top of these enclosures, in each LV room and data hallThis is one of the custom transfer boards being pre-staged ahead of fitment to the plinth and cableway enclosure, as seen aboveThis is the transfer board for the B-side LV room in place and fully tied into the wall, ready for commissioning in due courseA closer view of the transfer board in the B-side LV room – the custom Netwise orange finish really pops against the monochrome technical space colour palette The same board, but reflected in the A-side LV room
We’re very happy with progress over the past few weeks, as we march further into the final stage of deployment for phase one.
Much of the work this time around has been labour intensive and highly physical, resulting in massive adjustments to both the cooling and electrical sides of the project. This all sets up nicely for the building-wide under floor containment to be installed from next week, leading into a four week period of high-activity on-site as the facility is energised.
We’ve reached a relatively pivotal point in the project now, in that the dominoes we’ve been lining up throughout the last few weeks / months are now ready to be pushed, which will lead to massive change in the next four to six weeks. Ultimately, this next phase will take us through to onlining and commissioning, and put us in a position to bring the first client systems online, and launch the site as phase one (aka Data Hall 1) completes.
What else has been happening?
Aside to the usual build works, we’ve also been hard at work implementing wider improvements across our operation.
Our London Central facility enjoyed a deep clean last week, including a full re-coating of the anti-static floor in all technical spaces.
We upgraded our core routing fabric in Telehouse North, as we prepare to deploy additional capacity in Telehouse North 2 next month. This is something we’re very excited about, as we move into the newest building on the Telehouse Docklands campus for the first time. We’ll be upgrading our Harbour Exchange / LD8 and City Lifeline fabrics very soon.
Civil works have now begun on both our grid feeds and our main fibre incomers, with visible roadworks now underway in the area surrounding our new facility. We’re very excited to see these critical services edge ever-closer to the site, ready for connection and use.
What’s next?
In the next week or so, the energisation process begins. This will last around a month, taking us from the current state to having full and final energy pathways deployed within the facility. This includes the work in getting our new feeds from the grid to our building.
A slightly later-than-planned update to the build blog this time around, thanks to time spent on more critical development works, as we head into a period of extended activity on-site at NLE.
The last four weeks have seen excellent progress across a varied range of areas, bringing a number of outstanding side-projects to a close, and solid advancements made on some of the remaining primary tasks.
Weekly overview
We’ll be keeping the update this week brief, so as to retain focus on real-world progress, however this post will serve as a general visual update to our readers, showing advancements across the various areas which have seen the most apparent change.
As seen at NLC, we’re blanking off the gate and turnstile sections of the front compound fencing, for added visuals and security – the turnstile sections are to followThe final outstanding checkerplate has now been installed, seen here in the ground floor level loading bayBoth the ground and first floor level loading bays have had checkerplate and bash protection installed, allowing the forklift to bump into the stops here for accurate, guess-free loadingThe intake louvres are now complete, pending their filter frames being installed in due course – here you can now see both top and bottom runs in placeHere is an external view of the two intake louvre runs for Data Hall 1This is the continuation of the intake louvres beyond the first floor data hall fire escape routeThis is our shipment of soaker sheets for the roof aperture profiles, which will take the extraction cowls A view of some of our newly installed extraction cowls, as fitted to the roof of the cold corridor for Data Hall 1 – these will take warm exhaust air out to atmosphere when not required for recirculation, and are in this position to avoid any possible heat loops with the intake side of the primary cooling systemOur LV rooms have preparations well underway to receive the main switchboards – the first part of this is preparing the open floor apertures for the incoming custom equipment plinthsThis is the main open trench for the primary switchgear in LV Room B – the custom plinths will sit inside this opening, with the floor finished to the front and back side of the framesHere we see our custom PDU expansion boards which will affix to the bottom of our Mardix PDUs in the data halls, allowing for our circuit monitoring to be installed on each rack feedWe’ve now started installing the ceiling tiles, as overhead works on the fire detection and lighting systems reach their conclusion – this has really started to finish off each room, giving a better indication of the finished surfacesHere we see the tiles installed in position above the eventual location of Pod 2, inside Data Hall 1
The most keen focus has been spent on the cooling system, in terms of the handling of air in and out of the building.
Beyond the visible updates as presented above, we’ve also been able to continue with underlying developmental plans for the remaining work phase, including aspects of power and connectivity.
Our fire contractors are now close to completion, which will be another major system milestone checked off very soon, as we march towards client deployment readiness.
What else has been happening?
It’s been a bumper start to Q2 here at Netwise, as we help a wide range of new and existing clients grow and deploy in our London Central facility. We’ve also started showing new prospects around London East as it moves nearer to completion, with a range of racks in the first pod now allocated to incoming clients.
We’re also close to pushing out a press release announcing our first major on-site carrier, so keep an eye out for that in the coming weeks.
What’s next?
Works are continuing on power, fire and connectivity. These are the main focus as we move towards the summer months, and to our forthcoming launch – watch this space for updates on when our first on-site events will be held.
