Lift slab construction

This method of construction simultaneously began development in 1948 by both Philip N. Youtz of New York and Thomas B Slick of Texas.

[2] Northrup Hall was the first full scale building erected using lift slab construction.

In turn, these trusses extend out from two reinforced concrete cores which provide the main structural support for the entirety of the building.

[7] The failure of the structure has been primarily attributed to instability with the steel columns that were meant to support the floors.

Although other factors were involved in the collapse while under construction, it is the insufficient lateral bracing that ultimately caused the structural failure.

[8] Northminster Car Park in Peterborough, England, built using the lift slab technique, was found to be unsafe and beyond economic repair in 2019.
