Member Since: 1983

MKA’s passion is creating structural systems for buildings of all shapes, sizes, and complexities and civil site and infrastructure designs for architectural projects. In addition to traditional structural and civil engineering services, they offer enhanced expertise in seismic, wind, vibration, existing building, performance-based, and blast engineering and site strategies for low-impact design, site infrastructure planning, strategic water planning, and excavation shoring.

MKA has been presented with a top national ACEC engineering design award (the most significant recognition by their peers) 26 times in the last 29 years–three times more than any competitor engineering firm in the United States; and the ""Grand Conceptor"" award three times. Collectively, their projects have won 500+ awards from a variety of industry organizations. If it can be done, MKA can do it.

Building Completions Timeline

 

Construction Time Chart

NOTE: Construction start time is not available for all buildings. The average construction time is only displayed if there is three or more buildings with construction start and complete data in that year.

 

Gross-to-Net Height

NOTE: Gross-to-Net Height is defined as architectural height minus height of highest occupied floor. Therefore, the Gross-to-Net Height is only calculated for buildings that have both the architectural height and the highest occupied floor height recorded.
