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.

Buildings

Please note that all heights shown in italics/red are estimated heights. These have been calculated based on known floor counts for the building, then extrapolated through analyzing typically hundreds of buildings of the same function on this database that do have confirmed heights. The user should be aware that non-standard building features, such as significant spires or raised entrances / podiums, may affect the accuracy of these estimations.
