HGA delivers integrated engineering solutions for critical infrastructure projects, including airports, structured parking, retaining walls, and detention systems. Our airport work demands rigorous coordination, where every detail—from airside structural requirements to landside access and circulation—must support fast-paced schedules and active operations. In structured parking, we optimize layout, durability, and flow to meet high-volume demands while balancing cost and constructability. Our expertise in retaining wall design includes cantilevered, gravity, tie-back, and soil-nailed systems engineered to handle complex grade changes and challenging geotechnical conditions. On the civil side, we design detention systems such as below-grade vaults, cisterns, and open ponds that manage runoff, conserve space, and meet environmental compliance standards. Across all infrastructure types, we deliver functional, efficient designs that respond to site constraints and perform over time.
