| Abstract: |
This paper presents a live design of a new fourteen story luxury condominium building in Union City, New Jersey, USA. Because of a misreading of the design drawings, the contractor poured lower grades of concrete than designed for certain crucial columns. This resulted in about 12 columns being built with less than 85% of the design strength. To obtain the necessary in-place compressive strength of the built concrete columns, they were enlarged using a combination of surface doweling and form-and-pump installation techniques. |
