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.
