Weeks 42-45
In order to realise LAB42, the heads of 332 piles must be trimmed. In Dutch, the construction term for this is koppensnellen. Trimming involves removing excess concrete from the uppermost portion (the head) of each foundation pile, exposing the rebar so it can be connected to the foundation beams or piers. This work is set to begin in week 42.
