Montgomery County Executive Office Building Plaza Replacement


Executive Office Building and Montgomery County Circuit Court Plaza Renovation


Location: Rockville, MD 

Owner: Montgomery County Maryland

Engineer: Smislova, Kehnemui & Associates, P.A.

Project Duration: 18 months


The Executive Office Building and Montgomery County Circuit Court was constructed in 1974.  The plaza is located between both the Montgomery County Executive Office Building and the Montgomery County Circuit Court Building. In addition, residential condominiums are located directly across the street.  Hence, the local noise ordinance restricted night time work.


Deteriorating finishes and an aging (40+ years), failing waterproofing system that had resulted in numerous leaks to the spaces below required repairs. 


The scope required the following: 

  • Complete removal of the existing overburden to the structural slab
  • Removal of the existing waterproofing
  • Identifying and repairing the structural slab
  • Installation of a corrosion inhibitor on the entire structural slab
  • installation of 215 mils of hot applied waterproofing
  • Installation of new expansion joints
  • Laying out and installing new finishes including an asphalt drive, granite clad planters, installing the associated landscaping, concrete walks that provided a dedicated ADA pathway, relocation of existing storm drains and the installation of new storm structures (15 and 18 inch storm lines), and all necessary signage.  
  • Since, the public accessed the 23,500 square foot plaza daily, temporary, dedicated walkways were constructed and installed during the project duration.
