Target
In the Dog Leg area, the blinding for the slab for the in-situ retaining wall on the north side was cast last week, and reinforcement is now ongoing. The first part of the base slab is planned for casting next week, after which work will start on building the 8m high, 25m long wall. The very last high bay slab was cast last week, as the screed for part of the Accelerator to Target was poured. Work on alterations to the pillar bases has progressed well and erection of steel for the rest of the Monolith/Utility high bay slab will continue.

The very last installation of waveguides inside the RF stubs was completed by ESS Polish in- kind partner IFJ Pan last week. This covers 21 out of a total of 27 stubs, as the last six stubs are for contingency and future upgrades. The stub installation project started about 2.5 years ago, when the ESS Accelerator Division, together with Skanska Direkt, made a mock-up, with waveguides, of the stub installations. Following a few minor adjustments and improvements later, the completed installation of waveguide components is a great achievement for ESS and another step towards the goal of first science in 2023.
The very first base slab casting of the Waste Treatment Building is now planned for the coming week, after additional reinforcement was added to the scope.
Internal finishing work is ongoing in two of the Lab Buildings, as well as system acceptance tests and other inspections, in preparation for handover. The subsequent period will be used for a Sectional Handover Inspection and closing of any issues found, before the Official handover to ESS in December. At the same time, work on completing the external area is ongoing and is expected to be completed by mid-November.
