Your Source for Excavation Support Designs, Consulting, and Management
At FNA, we pride ourselves on being a multidisciplinary firm with unparalleled knowledge of complicated deep excavations. Based on the unique specifications of your site, we plan and design an excavation support system most beneficial for your structure, budget, and timeframe.
Along with designing deep excavation support systems, FNA is your one-stop shop for temporary sheeting and shoring, top-down construction, and underpinning foundations. Our excavation wall support systems and retaining structures include:
- Pile walls
- Sheet piling
- Soil walls
- Soil nail walls
- Soldier piles and lagging
- Secant piles
Our efficient excavation support methods are an invaluable asset for projects that require the safe construction of shallow or deep foundations, one or more basements, and utilities. And as a value-added component, our solutions save cellar space and eliminate the cost of additional foundation walls.
FNA engineered the deep excavation support systems and designed the deep foundation for 432 Park Avenue, the tallest residential building in the world and the second-tallest structure in New York. A project of this magnitude required superior planning, intricate designs, flawless execution, and innovative solutions to ensure safe and effective completion.
Despite being located in the heart of one of New York’s busiest areas, we are able to successfully maneuver through tight areas and uphold the structural integrity of the adjacent structures while excavating the site of a 1,396-foot skyscraper that is now home to some of the most valuable real estate in the world.
