Existing Service
For existing electrical systems our engineers thoroughly investigate and document, among other items, the electrical service entrance switchgear design and feeder and breaker sizes so that we know exactly what the service is and its limitations given a buildings existing and proposed electrical demand. 

New Service
For new building electrical design, it is imperative that the type of electrical service available in a neighborhood in which the new construction will be is known before design begins. The design of a new electrical system begins early in the MEP design process and develops in parallel with the mechanical, plumbing and fire protection trades. Our engineers carefully account for all existing and new electrical loads and apply the appropriate demand factors and allow for future expansion. Our engineers always seek opportunities to build in value and save money in their designs. 

  • Normal and Emergency Electrical Power Design
  • Regular and Emergency Lighting Circuiting and Switching
  • New Electric Service Switchgear Design, Main/Sub-distribution panels, Feeder and Conduit Sizing
  • Emergency Backup Power Systems and Generator Design
  • Electrical Load Letters
  • Short Circuit/ Arc Flash Analysis


For each project AEP conducts a thorough review of the applicable building and life safety code to identify elements and requirements that make up an appropriate fire alarm system and how environmental and system conditions trigger various signals such as alarm, trouble, and supervisory signals; which are then used to initiate responses or behavior. AEP also focuses on power supply requirements and circuits that drive and connect the building blocks of fire alarm systems.

A fire alarm system is installed for protection of life and property. A fire alarm system must be able to perform the following functions:

  • Detect the presence of smoke, fire and carbon monoxide
  • Notify the occupants
  • Notify the fire department (usually through a central station connection)
  • Engage safety protocols of life safety systems such as elevators and emergency egress lighting
