Where needed, the assessment may recommend additional testing or specialized electrical studies.

Electrical Load Analysis

Electrical systems are often modified over decades without a complete understanding of the cumulative load being added.

RAS Engineering can perform load evaluations to determine whether existing electrical systems have sufficient capacity for proposed improvements.

Load analysis may be required for:

  • New HVAC equipment

Services may include condition assessment, system planning, load analysis, equipment replacement design, and coordination with existing building infrastructure.

Electrical Engineering for Condominium Buildings

Condominium associations frequently encounter electrical issues during capital improvement projects, building recertification, insurance review, renovation, or equipment replacement.

Common electrical engineering needs include:

  • Main electrical service evaluation

  • Aging panel replacement

  • Generator upgrades

  • Electrical-room restoration

  • Pool equipment electrical upgrades

  • Garage lighting and power

Electrical work should be coordinated with concrete restoration and waterproofing repairs so new equipment is not installed into an environment where leakage remains unresolved.

Electrical Engineering for Building Restoration Projects

Restoration projects often affect existing electrical systems.

Concrete repairs, waterproofing, façade work, garage restoration, roof replacement, and equipment replacement can require relocation, protection, or redesign of electrical components.

RAS Engineering can assist with:

The objective is to determine the probable cause of the observed condition and establish an appropriate repair strategy.

Why Electrical Problems Should Be Evaluated Early

Small electrical deficiencies can become larger operational problems if left unresolved.

Warning signs may include:

  • Repeated breaker trips

  • Overheating

  • Burned insulation
