For traditional plan-spec projects, an architect will hire an engineer to produce drawings for a project’s mechanical, electrical and plumbing work. Subcontractors in each of those areas will then bid the project, and those that are awarded the work will utilize those drawings.

In design/build projects, the subcontractors themselves either have in-house engineering capabilities, or they often are aligned with an outside strategic engineering partner. Collectively, they work with the architect and owner to develop the design and drawings in accordance with that owner’s vision.

We offer complete design-build capabilities with in-house engineers and project managers.  The single-source capability of a design-build structure lends to reduced job costs and fast-track the development of a project.

DOES O'CARROLL ELECTRIC CHARGE FOR ESTIMATES?


ESTIMATES ARE PROVIDED AT NO CHARGE REGARDLESS OF PROJECT SIZE




WHAT SUPPLIES AND EQUIPMENT DO YOU USE FOR A JOB?


We have partnerships with the top electrical suppliers and vendors in area, including Steiner, Amperage, Sunrise Electric, Welch Bros., Connexion, Lift Works. We also have in-house scissor lifts, backhoes, skid steers, trailers, and thousands of electrical supplies SKUs. All installed products.




ARE YOU LICENSED, BONDED, AND INSURED?


Yes! And we are glad you asked…no matter who you end up hiring, make certain the contractor is licensed, bonded, and insured! We carry general liability insurance, bonds, and worker’s compensation insurance. We are licensed throughout the Chicagoland area.





How do you differ from a residential electrician?


A residential system typically includes a 120/208 single-phase service - this includes light transformer, breakerbox, and circuits. Commercial and industrial work requires more skill, experience, and attention to detail. Controllers, contactors, relays, transformers, raceways, and sensors and many other factors that require a well-trained, experienced electrical technician. The work is more powerful and dangerous, and a true reflection of how electricity makes the world work.




What can you tell me about lighting?


In a commercial environment, it's critical to have LED lighting throughout your facility. Within the past decades, it has become a no-brainer to have LEDs. Over the long run, you'll enjoy significant savings.




How long will it take for the work to be done?


Electrical contractors who are well versed with what they do will tell you the average time period it would take them to complete the task at hand. Some electrical assignments can be hard to estimate how long they will take to complete because of issues that arise along the way. If you will be paying the contractor on an hourly rate, it’s good to know how long it will take.




Does O'Carroll Electric charge for estimates?


No, estimates are provided at no charge. Depending on the scope of work, a series of photos may be sufficient, but most projects require an on-site visit, as well as access to blueprints or an understanding of your facility's electrical architecture.




What are your most common services?


Our most common project is a service upgrade - often the replacement of old, potentially unsafe switchgear or perhaps. These require the help of a licensed electrician - anything over 200A can be very dangerous




What's the difference between a union and non-union electrician?


UNION ELECTRICIANS ARE SUBJECT TO RIGOROUS TRAINING AND A 4-YEAR APPRENTICESHIP PROGRAM. THEY ARE TRAINED IN THE LATEST IN SAFETY AND TECHNOLOGY, AND HAVE A LARGE SCOPE OF PROJECT WORK UNDER THEIR RESUME, INCLUDING HIGH-VOLTAGE, HIGH-CAPACITY SCENARIOS
