Why does it take 4 months to fix a runway?

[Kharma Police]

why does it take 4 months to replace a runway at JFK while it only took a month to replace one in ATL? I know the JFK runway is considerably longer, maybe a civil engineer could enlighten us on the reasons for the extended time frame?

Because the mafia contractors said so!

Union vs. non-union probably has a lot to do with it.

It can be done in three weeks if you really want to...

"In just 20 days, construction crews laid 100,000 tons of asphalt, the equivalent of 2 miles of I-5...."

I'm sure the first three months are a no show job for several contractors

The pouring of concrete took three weeks, but the whole runway project at SEA took just over four months - the same as JFK.

At ATL they just put down a new layer of asphalt which can be done fairly quickly. Both JFK and SEA projects involved taking it all away down to the dirt and starting fresh. But the results at SEA were worth the wait with the new runway very, very smooth. Hopefully it will be the same at JFK so they'll remove the 'pogo-sitck' effects at the beginning of 31L.

Maybe the same "slept-at-holiday inn express last night" pax that try to tell flight crews how to do their jobs could give the Port some advice.

First, they need to take of 36 inches of asphalt etc. Then they are planning on shoring up the bed of the runway so there is less migration of the controlled surface, then they are going to put down no less than five layers of asphalt and concrete. 13K feet of runway, in the spring time in NYC. That sounds about right given that JFK does not have the weather of ATL.

Like the know-it-all pilots on FlightInfo are doing on this thread?
