We breathed life into many of the main power systems for the first time in this instalment, with commissioning actions underway on our primary switchboards and our backup generator systems.
The push towards phase one completion has seen many exciting milestone events reached in a short space of time, which is always great to see. We’ve energised the main switchboards, integrated and tested the generator failover, and removed the temporary site power, amongst a range of other system commissioning tasks.
Weekly overview
Things are sharpening up quickly on-site, as a wide range of systems begin to spin to life for testing and commissioning, ready to begin serving client kit in due course.
We’ve hit a number of milestones this time around, including the testing and commissioning of our cooling systems throughout the building (both critical and comfort), and the same point reached on our fire detection and extinguishant panels, both building-wide and the enhanced systems in critical spaces.
The speedgate area has been carpeted through from the main entrance and reception, to finish off the space ready for client arrivalsThe cooling systems throughout the building have now been commissioned and tested, with cold and warm air now available in all critical spacesOur UPS commissioning is well underway, with the main units now interconnected with the UPS output boardsThe building is now powered through the primary switchgear and distribution boards, with all temporary site power now fully decommissioned and removed A look across Data Hall 1 after it’s had its initial post-work clean, with one of the supplementary AC units open for commissioningA look across Data Hall 1, towards the first pod of racksThe four CREC units have now been brought to life, with cooling, recirculation and extraction now tested and provenBoth the primary CREC and supplementary CRAC systems feed into the shared underfloor plenum, which will distribute closely controlled air to all footprints in DH1The entrance into the cold corridor in Data Hall 1 is the first view of our new signage design language (just visible here!)The view towards the A-side power distribution in Data Hall 1, with ODF A visible on the right hand sideThe primary CREC system has now had all filters installed – here we see the 28x quad-fin air intake filters, this being the first layer of filtration before hitting the multi-stage filtration inside each coolerIt’s been very exciting to see the cooling system spun up for the first time, and fantastic to see the real-world culmination of all our design and simulation workHere we see some of the detail as you enter the cold corridor from Data Hall 1, showing the lighting system and the access hatch for the otherwise-sealed extraction loopOur warehouse and loading bay now has large floor lettering / numbering on each receiving dock door for quick and easy identification while loading and/or unloadingThese large format letters / numbers all form part of our new design language, which has now begun to roll out throughout the facilityWe’ve opted for a more modern approach to our signage at London East, an evolution of the design at London Central – simplicity and clarity is the main order of the day hereAll internal signage is now direct-application vinyl, in our custom font to match all digital and print assets – aside from a few 3D logo and type elementsHere we see one of the larger multi-directional signs to guide visitors around the facilityEach corridor and main customer route has multi-directional signage in place to guide visitors through the buildingThe frosted / etch effect pod door vinyls have returned, as found at NLC as part of our rebrand in 2019Visitors will now see wifi access points and access control beacons in various places throughout the facility – the wifi is an extension of the mesh deployed at London Central, meaning you’ll automatically connect at East if you’ve already done so at Central
As you can imagine, with much of the work on-site now commissioning actions, presenting this visually for the build blog is tricky. We’re hoping to put together another fly-through video soon, to show phase one completion.
Another unseen but extremely critical area which reached completion this time around is our fire stopping, which has now seen all additional wall apertures cut in since initial construction fully sealed and certified. This ensures that the building fully complies with our extremely strict fire design and operation policies.
With all of the broad strokes of the project now complete, we’re able to begin working through the more detailed finishing work, while system commissioning actions continue.
What’s next?
As is to be expected at this point in the project, more of the same.
We’re quickly moving towards welcoming in our first client systems, with the final set of work ahead of this to focus on UPS systems, network integration, and general facility commissioning (things like onlining our NOC for CCTV and systems monitoring).
The pace has certainly picked up now, as we push towards phase one completion at London East.
This acute focus has left little time for the blog, and as broad strokes visual change has slowed down at this point, we’ve put together a four week short summary of the last month on-site at NLE.
Weekly overview
Phase one completion will see the facility ready to take its first clients, which is an enormous milestone for us here at Netwise.
There will still be some ongoing works beyond phase one, which will include things like our customer lounge and some other secondary niceties, as primary focus at this point is getting the technical spaces completed and ready to receive live client systems.
Looking slightly further ahead still, phase two will involve the preparation and roll-out of further technical space, making use of the other data halls, which given the amount of work put in ahead of time for this will certainly come to fruition much more quickly. This is expected in 2022, and will be based on a dynamic roll-out schedule, driven largely by demand.
The largest area of progress in this instalment of the build blog has been centred around air conditioning. This is not our primary cooling source in the technical spaces at NLE, with that role falling to our extremely efficient adiabatic systems, however traditional AC does still play a crucial role in both supplementary cooling in critical spaces, and comfort cooling in customer and staff areas.
This is a view inside the cooling control system unit for Data Hall 1, as the internal termination reaches completion The pipework for both the supplementary CRAC systems and the comfort cooling throughout the building are comprised of some very long pipe runs, depending on the location of the internal equipmentSome of the pipe runs for the AC systems have been fairly complex, because of their routes, and because of how split systems have their pipework distributed between endpoints One of the main convergent runs of AC pipework can be found on our storage mezzanine, as the runs cross towards the exterior condenser areaHere we see one of the main runs coming together, which traverses the storage mezzanine before reaching the exterior skin and turning down towards the point of exitPower cabling also joins the pipework runs, with drainage to followHere’s a snapshot of the complex manifold work happening in one of the ceilings, as the split systems are evenly distributed to ensure even pressureThis is the AC unit in the build room and customer breakout area, as the cabling begins to be terminated internallyAll comfort cooling systems have in-room control panelsThis is the control panel for the system in another customer amenity space, which also allows for remote operation and monitoringHere we see some of the external condensers being worked on by our AC engineersThe external condensers are laid out in a grid which enables plenty of future growth The larger condensers here are for the supplementary downflow units in the data halls, temporarily stood on their rubber feet ahead of permanent fixture Here we see the overhead lighting system installation underway in the cold corridor area for Data Hall 1 – this is where external air is filtered and processed for our primary CRAC systemThe UPSs and UPS switchboards are now in place and terminated in LV B, to match the state in LV AOur main LV switchboards in both LV rooms have now had their line diagram vinyls fitted, taking both boards to completion ahead of energisation for commissioning and setupThe line diagrams are fitted to all switchboards, including the smaller sub-boards for the UPS systemsHere we see one of our custom designed security panels fitted to Pod 1 in Data Hall 1, for the privatisation of racks within said containment systemWe’ve now fitted the razor wire to the top of our compound fencing, which aside from adding electric motor controls to the main gate, takes this area to completionThe razor wire now runs the entire perimeter of the facilityWe designed a custom implementation of the razor wire retention system to allow for the retraction of our large vehicle access gateAs part of the final stage of work, we’ve had any construction marks and / or damage on our metal clad panel walls repaired, which included full panel respraying where necessaryAny panels with damage incurred during the build have been returned to factory conditionThe spray team were able to achieve a truly flawless finishWe’re very pleased with the outcome of the retouch and repair works undertaken throughout the facilityThe VESDA pipework has now been installed in both LV rooms
As you can see, NLE is still an extremely busy site, with lots of finishing stage work underway. Yet so much more of the work being undertaken at this point is not of a visual nature; commissioning of power systems, access control, network setup, CCTV etc, these are all tasks with little to photograph. However progress across all of these areas will be relayed when suitable.
We’re certainly entering into an exciting period of the build, as major systems begin to see energisation for the first time.
What’s next?
More of the same as we head towards phase one end-out. Keep your eyes peeled for the next instalment of the blog, which will show much of the major infrastructure being onlined for the first time!
Now that raised floors have started to go back down, and termination of cabling is essentially complete, impactful visual change has slowed down slightly, however progress is still pushing forwards at great pace.
We’ve been preparing for some of the final trades to land on site to end-out phase one, which will include the CRAC pipework team and the wall fabrication team from earlier in the project, who will be finishing off some of the final cooling system segregation now that the fans are installed.
Weekly overview
Much of the change this time centres around supplementary cooling, VESDA / fire panels, and data cabling for things such as CCTV, access control and monitoring / system control.
We’re now very much in the end-out phase of the project at this point, which means that various elements that until now were operating separately are coming together quickly.
For example, our evaporative cooling units are now connected back to both their power delivery and control systems, meaning that they will soon be ready for their first spin up and test. This is the same for a number of the core systems which make up the infrastructure of the facility.
We now have most of the building-wide comfort cooling in place for client and staff areas, including here in the build room and customer loungeHere we see the ceiling mounted AC unit mirrored on the other side of the building, and the same units are now also present in the NOC / officeWe’ve also got three high performance models installed in each of the LV rooms, with room for a fourth in due course as and when required based on UPS expansionOur VESDA pipework is now installed in Data Hall 1 and pre-emptively in Data Hall 2This is the view of the installation in Data Hall 2, which we are pre-staging for future use, along with all other baseline infrastructure – this will speed up the commissioning process for this hall dramatically once it’s neededThis is the view of the VESDA installation in Data Hall 1This is a slightly wider view of the VESDA installation in Data Hall 1, showing the various sampling pathways as they leave the main unit, and also showing the B-side PDUs for distribution to client racks, and the earthing bar for the hallHere we see the VESDA pipework installed in Data Hall 2, along the blanking system at the rear which will eventually house the CRECs for this hallThe CREC units in Data Hall 1 have now had their power and control system cables installed, which brings them up to readiness for commissioning in due courseThe ODFs in Data Hall 1 are starting to take shape, with containment now run in from both high and low levels – here, one of the newly installed cleaner sockets is also visible, as part of a wider ring installed throughout the building to support such requirementsThis is the B-side ODF, with a range of cabling now run back to it to support various functions in Data Hall 1, such as CCTV, monitoring and system controlsHere we see the entrance to the first committed private pod in Data Hall 1, which after some forthcoming adjustments to access control and visual identity, will be handed over to the client in Q4Another view of the pod entry door systems that we use with our APC racking and containment system, which are operated electronicallyThis floating, conduit-free cleaners socket is achieved by ensuring that it backs onto one of our risers, meaning all containment for the cabling is hidden from view, something we have done wherever possible for a clean installationThis is the cleaners socket as installed alongside ODF B in Data Hall 1, which due to its positioning does require conduit access to under floor containmentThe UPS boards are now landing back in place in both LV rooms, having been removed during the flood cabling processAnother view of the PDUs which distribute B-side power in Data Hall 1, with all internals now completely terminated, and ready to hand-off power to client racksWe now have our new reception desk standing in place, which will be finished with branding and a glass security and visitor flow system in due courseAnother view of the reception desk as placed in an approximation of its final position
We’re getting to the point at which photographing visual change is likely to slow down somewhat, as we move onto more detailed work such as the interconnection of critical systems, and the onlining of various electrical elements including CCTV and door access control.
Excitement is starting to build as the many months of extremely hard work from all those involved begins to show its final fruits, which will become all the more exciting as we start to see systems roar into life.
What’s next?
While build and installation works will continue in a few final areas – such as CRAC pipework, final airflow containment for extraction in Data Hall 1, and the end stages of general system containment – we are now also in a position to begin the early-stage commissioning process.
We are entering an exciting phase of the project, as things finally begin to slot back into place after a good few months of ordered chaos; a necessary evil associated with the extensive electrical work required to take the building from completed shell to functioning data centre.
Over the next few weeks, we expect to see the site visually return to a state of completion (for phase one), at which point the site will be onlined, and commissioning of critical systems will begin in earnest.
We have more exciting progress to share in this instalment of the Build Blog, as cabling continues to run into the facility at pace.
This progress has been seen across the board, from the largest runs out to external connection points, right down to the smallest termination points inside of the Data Hall PDUs.
Weekly overview
In the last two weeks, we’ve doubled the labour force involved in the electrical side of the project, adding a dedicated cable gang to the on-site trades to help push through the final cable runs, most of which are very substantial armoured cables.
This has seen the vast majority of the on-site cable drums emptied and returned to the vendor, as the cables now lay in place, with termination well underway across the board.
We also have a dedicated jointer on-site, who is heading up much of the largest termination activity, such as inside the generator canopies.

This has been a fantastic fortnight for project development, with tremendous progress on the cabling side of things.
We’ve been very excited to see all of the cabling begin to disappear under the floor and into the risers, ready for termination and testing. We’re also very excited to see some additional visual elements installed, such as the bright red VESDA air sampling pipework.
What’s next?
We will continue with progress on all things electrical. As cable pulling nears completion, focus will shift more completely onto termination, along with supplementary power installations, including small scale non-critical power delivery to things like cleaner’s sockets.
Beyond this, the VESDA pipework installations will continue, and with the arrival of additional cabling for things such as the CREC control and monitoring system, this will also begin to take shape.
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).
