The Retreat at Seven Bridges

Woodridge, IL

Retreat at Seven Bridges apartment complex entrance


Design/build constructor REX Electric and Technologies partnered with GBA for preparation of permit drawings to add new electric vehicle chargers to the suburban Chicago apartment complex.

Electric Vehicle Charger Permit Drawings

The Retreat at Seven Bridges is an apartment community of one-, two-, and three-bedroom residences, as well as multiple amenities such as a health and fitness center, swimming pool, and clubhouse. As part of the owner’s continuing efforts to offer appealing amenities to residents, this project added two new electric vehicle chargers to the complex. GBA worked as a subcontractor to prepare permit drawings for the project, which was performed as a turnkey design/build project by the prime contractor. The installation included concrete foundations, conduit, trenching, and all necessary electrical work.

The chargers involved installation of a new eight-circuit 120/240V NEMA-3R single-phase load center affixed to one of the existing multifamily apartment buildings to provide 240V circuits for the new chargers. The load center is fed from a vacant position in existing meter stacks for the building.

GBA’s responsibilities included a drawing set consisting of:

  • An electrical site plan (including an enlarged power plan showing the charger installation)
  • An electrical single-line diagram
  • Electrical details
