We have been working for city, county and state agencies for over two decades, providing design services for vital transportation and infrastructure projects, including bridges; streetscape and street reconstruction; major utility and drainage upgrades/modifications; waterfront structures; parks, greenways and green infrastructure; and industrial and wastewater facilities. Our core design services encompass structural and civil engineering; architectural and MEP design; structural integrity evaluations; facility condition inspections/assessments; land surveying and mapping; and material testing and special inspections, including disaster recovery and emergency response.

Our portfolio includes bridges over waterways and rail facilities and complex, high-profile pedestrian bridges. Many of our projects involve bridge rehabilitation or replacement in complex urban settings and high-trafficked areas. We also deliver rehabilitation designs for major, stand-alone retaining walls adjacent to high-volume roadways. Over the last decade, we have completed numerous street improvement and reconstruction projects involving safety and traffic improvements, Americans with Disabilities Act accessibility, drainage improvements and major utility work. We also deliver projects that involve site development for commercial, residential and public facilities. HAKS also has an impressive portfolio of parks, green infrastructure, greenway, and recreational projects as well as shoreline restoration work involving improvements to roadways, walkways, stairways and drainage outfalls.
