The closest analog to what Blue Origin is attempting to do, therefore, concerns the rebuild of Space Launch Complex-40, which was largely destroyed by the AMOS-6 failure.
According to Muratore, SpaceX was not allowed to begin reconstruction work at the launch pad until January 2017. The delay stemmed from the ongoing investigation, which included a grid-by-grid examination of debris, cataloging recovered materials, and launch site remediation. Muratore and other SpaceX engineers spent these four months redesigning the launch pad.

Trip Harriss, who managed the Falcon 9 fleet operations in 2016, said everyone at the company pitched in to support the investigation and then the reconstruction of the SLC-40 pad. The search for debris lasted from shortly after the explosion until early October, when efforts had to be abandoned due to the approach of the powerful Hurricane Matthew.
During this time, SpaceX pulled out all of the stops, deploying drones and aircraft with sensitive equipment. “At one point, I got a submersible to take into the flame trench, where there was an accumulation of water, to see if we could find any rocket debris,” Harriss said. “But it was just large chunks of concrete.”
Going fast
Launch pads are among the most complex pieces of infrastructure involved in sending a rocket into space. They require a lot of braun, as evidenced by the need for tall and strong steel launch towers. Then there’s the large amount of concrete used for the foundation, flame trench, and surrounding areas.
Last Thursday, during the test failure, one of Blue Origin’s massive launch towers toppled, and the other appears to be seriously damaged. The concrete underneath the rocket also appears to have collapsed in some places. From a structural standpoint, there is likely a significant amount of work ahead.
