Arlington County Public Schools: Yorktown High School

Project Overview

The Yorktown High School renovation replaced all of the existing structures (except for the 2004 addition and the house portion of the auditorium) encompassing approximately 300,000 square feet total, including a 19,000 square feet aquatic facility.


Renovation areas included:

  • Technology-enhanced classrooms
  • Studios and laboratories
  • Media center
  • Cafeteria and kitchen
  • Administrative offices
  • Theatrical lighting
  • Rehearsal rooms
  • Black box theater
  • Physical education spaces including competition and auxiliary gyms

The Ennis Electric team installed multiple state-of-the-art electrical systems including:

  • Fire alarm
  • Telephone/LAN
  • Intercommunication
  • Master clock
  • Lightning protection and separate auxiliary sound systems for the pool, gym, auditorium, band, vocal, orchestra and dance/wrestling rooms

The project also included the installation of low-voltage relay control panels, motion sensors and daylight photocells to harvest daylight, limit lighting in unoccupied spaces and control for the local HVAC units to conserve energy. A wireless network system was installed that covers the entire campus so students can easily access the internet anywhere on school grounds.

These renovations took place while the school was occupied. The Ennis Electric team and partners had to develop a construction plan that allowed the school to remain operating during renovations.
