News: Pouring concrete for mezzanine floor

The construction of the mezzanine is chugging right along. Its subfloor is laid, all the systems including cabling and sprinklers are now installed - and everything works! This week we can start on the big job: pouring the concrete.

Pouring in four phases

We’ll pour the new concrete floor in four phases. The main reason for this is that the total floor surface is around 900 square metres. This means having to pour a total of more than 160 cubic metres of concrete onto the subfloor. Doing this all at once requires 16 concrete mixers and a concrete pump attached to an almost 100-metre long concrete hose to deliver it to the pouring site. Once poured, we would still have to level it all, but this would take so much time that the concrete would start to set before we could finish. This is why we’ll do the job in four phases of about forty cubic metres per pour.

A tight schedule

The time schedule is tight. We’ll be pouring the concrete at night, with preparations starting at 8:00 p.m. The actual pouring will be done from 9:00 p.m. until 1:00 a.m. The next hour will be spent on clearing things away and cleaning up Departure Hall 1 so that passengers can catch their flights in the morning unaware of our activities.
