ᐅ Severe weather warning level red for our construction area tomorrow!

Created on: 12 May 2018 21:13

Hello everyone,

A severe weather warning has been issued for our building site tomorrow from 2 p.m. to 5 a.m. the following day. It is a red alert with warnings of heavy rain, hail, and hurricane-force winds.

At the moment, our base slab is prepared for the concrete pour scheduled on Monday.

Current status:

- 18 cm (7 inches) of perimeter insulation installed
- plastic sheeting on top
- spacers and one layer of reinforcement steel

Can I leave everything as it is shown in the picture without worry, or should I secure anything or take other precautions?

Could hail cause serious damage to the plastic sheeting or the perimeter insulation?

Foundation construction site with reinforcement steel mesh, gravel, and adjacent house

Thanks in advance,

greetz Jörg

If the concrete is scheduled for Monday, the construction manager should already know how far along things are.

I don’t think so, the construction manager is 300 km (190 miles) away, and I don’t believe he pays attention to severe weather warnings, anyway.

Why does everyone always think the embankment is so vulnerable? The earthworks contractor, structural engineer, and construction manager don’t see any issues with it. The embankment is only 1.30 m (4 feet 3 inches) above ground level in the lowest last sixth; 3 m (10 feet) towards the north it’s down to just 0.80 m (2 feet 7 inches) above ground, and from the middle we’re already cutting into the terrain...

The rebar isn’t twisted together yet, and there’s only a single layer.

How would you secure things now? I mean, with what materials? All stores are closed, do you have a 150m² (1,615 sq ft) tarp at home 🙂

The steel is already in place and tied together. It's unlikely that such a mat would be lifted by wind. At most, a construction fence might fall over if there's a sign on it, or the portable toilet 🙂

So, better not stay in the portable toilet ))

We still don’t have a portable toilet; the general contractor messed that up....

Consider yourselves lucky... in storms with portable toilets tipping over, it’s not pleasant... and no one comes quickly to clean it up 😉

With rainfall up to 45 liters per square meter per hour (1.5 inches per hour) and localized (probably passing) thunderstorms, no pile of stones will wash away there. At most, no more than 10cm (4 inches).

If I were the site manager, I would be interested in the building I’m responsible for, including weather warnings (which still aren’t issued for Ingolstadt). But I guess there are different site managers.

And if I were the site manager and knew that concrete was scheduled for Monday, I could be sitting in Hawaii and still be aware that the preparations are almost complete. However, if the top layer isn't in place yet and nothing is screwed together... then as a site manager, I would know that pouring concrete on Monday is unlikely. Knowledge does not depend on distance, at least not regarding the general construction process.

But there’s probably not much you can change anymore.
