BTC Completes Balcony and Parapet Wall Project at Groves of Palatine Condominiums

Building Technology Consultants, Inc (BTC) is delighted to announce completion of Balcony and Parapet Wall Repairs project at Groves of Palatine Condominiums in Palatine, Illinois.

The Groves of Palatine Condominiums include four seven-story buildings constructed between 2002 and 2005.  The floors of each building consist of hollow core precast concrete planks supported on steel framing and concrete masonry walls.  The exterior walls of the building are primarily clad in brick and cast stone masonry.  The exterior walls at the first floor of each building consist of exposed cast-in-place concrete.

Each of the 4 condominium buildings includes 56 balconies and two rooftop terraces at each end of the building.  The 2nd floor balconies, which are located over occupied storage space within the parking garages, are comprised of a waterproofing membrane and paver system.  The balconies at floors 3 through 7 consist of uncoated, solid, precast concrete slabs, which are supported by masonry walls and piers.  The rooftop terraces are enclosed by brick masonry parapet walls with cast stone accents and metal coping caps.

BTC had previously been retained to perform an exterior facade evaluation at the balcony columns and parapet walls.  BTC was retained in 2019 to design improvements to these components.  The design included supplemental balcony support columns at all balconies, as well as support brackets within storage spaces, along with rebuilding of the terrace parapet walls at all 4 buildings.  Waterproofing repairs and through-wall flashing replacement were also designed for each of the 2nd floor balconies.

To ensure work was performed in accordance with the design, BTC provided construction contract administration services during the 2-year construction phase of the project.  In addition to the support and parapet wall work completed during this phase, BTC identified areas for repointing of deteriorated mortar joints and replacement of deteriorated brick masonry on a unit-price basis.  Additional work also included removal and replacement of existing deteriorated expansion joint sealant.
