Markosky’s structural designs range from simple to complex structures requiring 2D grid analysis and 3D finite element analysis.


Markosky provides bridge rehabilitation, bridge replacements, culvert designs, sign structures, and retaining wall designs on large-scale highway projects to local municipal stream crossings. We understand that each project or client may require a different approach and we are agile and experienced enough to provide the appropriate level of detail required for each bridge.


Markosky’s engineering professionals have the expertise to provide innovative, cost-effective, sustainable engineering solutions specifically tailored to meet the needs of our clients. Early identification of the optimum structure arrangement and type make the design process more efficient. We have completed projects using conventional design methods, ABC techniques, design-bid-build, and design-build methods.


We are prequalified by the Ohio DOT for Bridge Design Levels 1 and 2 and Bridge Inspection Level 1
