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.
The first set of cables that make use of the external ladder runs out to the transformer, seen in place hereAnother view of the first set of cables on the transformer-to-LV room routeThis run takes cables all the way out to the transformer enclosure – these are again in a trefoil cleat arrangement, as with the LV Room interlink cablesThe GRP enclosure for the transformer now in place atop the previously poured baseThe cables that connect to the transformer take a direct route around the perimeter of the front compound, with rear-mounted security panelling to be installed soonAnother view of this particular containment run in the front compoundThis is the view back towards the building, with the containment and cabling penetrating the skin of the building, pending final capping and fireproofingSome of the newly emptied cable drums, which have since had their contents run into the facilityTermination of the main LV boards is now well underway, with a view here inside one of the main enclosures in LV Room AAnother of the main enclosures in LV Room A, with the termination now completeThis is a view of one of the main enclosures prior to any termination, after glandingHere we see one of the same enclosures mid-way through terminationThe same enclosure as it reaches completionThis view under one of the LV Room floors shows the next layer of containment and cabling going in over the top of the base layerA view of some of the ladder work on the first floor, which now contains the runs which will feed Data Hall 1 with protected, conditioned powerA look inside one of the PDUs in Data Hall 1, as the final termination beginsThis view shows some of the cables as they make use of the riser in LV Room BThis is the view of the external containment which heads to the generators, as the cabling nears completionAnother view of the generator cables as they enter the buildingA look across the rear of the generators, where this cabling will soon enter each unitThe generator cables enter the building here, and then pass into LV Room A for onward handling – these holes will all be fire stopped and finished with tight-fitting decorated panelsThe transformer route shown here now contains all cabling as necessary to liven up the site during commissioningAnother view of the transformer cabling, with the earthing now in placeA view of the transformer cabling as it reaches the enclosure, ready for connection into the transformer once that is installedHere we see one of our custom ODFs, of which there are two in Data Hall 1 for diversity – this angle shows the installed overhead cable ladder bridging across to Pod 1The VESDA pipework installation is now underway in Data Hall 1A look at the pipework as it begins to be installed along air pathways, in this case on the supplementary CRAC unit intakes, which now have their automatic dampers fittedThe pipework is also installed along the main CREC exhaust and recirculation louvres
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.
