Look Inside the KOP Mall Expansion Corridor

The King of Prussia Mall expansion project is officially half way through construction. On June 30th the final steel beam was placed and we had the opportunity to tour the 1,100 foot long corridor constructed with 5,000 tons of steel.  Now we want to give you a sneak peek.

In 2012, Simon, a global leader in retail real estate, chose Nave Newell as the civil engineer for their King of Prussia Mall project.  The 170,000 square foot expansion connects the Court and the Plaza creating one building totaling 2.86 million square feet of retail space.  The connector will have 50-60 new retailers, a dining pavilion and state-of-the-art parking garage with 1,100 spaces.

With the expansion situated on 130 columns and parking underneath, the team was challenged with a complex design process.  Nave Newell coordinated closely with the architect, MEP and structural engineers and the construction manager for major utility relocations and construction phasing, which was necessary to accommodate the active shopping mall during two holiday seasons.


One of the many rain gardens designed to collect and manage stormwater on-site.

Our engineers worked closely with both Upper Merion Township and Montgomery County Conservation District officials to achieve stormwater management requirements on a non-infiltrating site. We developed an innovative approach that included rain gardens, a complex drainage network within the building and significant underground basin design. Our landscape architects selected deep-rooted vegetation to quickly uptake the runoff and achieve water quality and rate control. With limited green space on-site, we also worked with the design team to direct runoff from the building’s roof to the areas set aside for stormwater. 

Within 9 months, Nave Newell secured all Township, County and State permitting requirements for the project. Construction is currently on track and scheduled to be completed in August 2016.
