Our Services

Combining our engineering capabilities with our construction expertise to make your project safe, efficient, and on-time.

Engineering and Construction

At Allison-Smith, we use our engineering capabilities combined with a thorough understanding of the design and construction information flow to overcome challenges typically found in today’s construction environment called design-build or design-assist.

Design Build

We have the ability to develop accurate budgets and precision designs with exacting detail. This comes from decades of experience manifesting itself in a wealth of historical information that you simply cannot get from a less experienced firm. This experience, combined with our expert team of project managers, engineers and proficient estimators, creates a customer experience that is second to none.

Building Information Modeling (BIM)

Allison-Smith’s BIM modeling process keeps project architects and engineers informed with an up-to-date model throughout construction-virtually eliminating the possibility of information loss between the design and construction teams. It also provides a BIM which can be utilized throughout the building lifecycle for future designs and facility maintenance.

Electrical Installation Drawings (EID)

The first to coin the term Electrical Installation Drawings, Allison-Smith Company is a leader in innovation and efficiency in the electrical engineering and construction field. We produce EIDs to clearly demonstrate every aspect of the electrical installation, laying the groundwork for a successful project


Prefabrication is an integral part of our construction process, and our unique approach to the utilization of Electrical Installation Drawings has allowed us to streamline this approach, bringing even more efficiency and productivity to every project.


At Allison-Smith, we have spent the last 10 years installing electrical modules and learning what works and doesn’t, while optimizing modular integration.

Service Department

Allison-Smith Company maintains a fleet of dedicated service vehicles that handle 24/7 service requests and provide continuous electrical maintenance for properties throughout Atlanta and the Southeast.

Our cost-effective design build planning processes allow us to effectively manage complex voice and data projects for the nation’s largest data centers.

Custom Electrical Equipment Manufacturing

We have the capability to design and build custom electrical equipment assemblies.  Clients often need products that are not available in the market for specialized equipment connections or for custom designed cabinets.  Our engineers can work with you to design and manufacture custom components that are UL and/or ETL listed.

Smart Buildings / IoT / BAS / AV

We have expanded our Voice and Data services to cover all aspects of building technologies.  Our implementation process is vendor neutral so solutions are designed to provide maximum value to the building.  The experience we have designing and installing low voltage cabling in buildings over the last 40+  years uniquely positions us in this market.

Lightning Protection Systems

Our lightning protection inspection services provide our clients with quality install and inspection services and verifies that inspected systems comply with national standards. Our UL-certified team has made the process of obtaining a lightning protection system quick and easy.

Building Operations Support

Our full time maintenance technicians can provide 24/7 supplemental maintenance coverage for your facility or we can design and implement a maintenance program to ensure your facility stays up and running.  Allison-Smith maintenance technicians keep facilities up and running.   Our constant commitment to training allows our technicians to stay ahead of the curve on safety, industry trends, and preventative maintenance.


Allison-Smith Testing is a fully certified testing group offering a wide range of testing expertise. Our technicians have achieved three levels of certification by the Snell Group in accordance with the National Electrical Testing Association (NETA) standards.
