What Architectural Engineers Do and When You Need One in South Carolina
Architectural engineers combine building design with structural and systems engineering
An architectural engineer is a licensed professional who works at the intersection of architecture and engineering. Unlike a structural engineer who focuses primarily on a building's frame and load-bearing capacity, an architectural engineer designs and coordinates the building systems that make a structure function—mechanical, electrical, plumbing, fire protection, and sometimes the structural frame itself. In South Carolina, architectural engineers hold a Professional Engineer (PE) license with a focus on architectural engineering, which requires passing the Fundamentals of Engineering (FE) exam, gaining work experience under a licensed engineer, and passing the PE exam in architectural engineering.
You might hire an architectural engineer when you're planning a renovation, new construction, or adaptive reuse project and need someone to integrate all the building systems into a cohesive design. They work closely with architects and contractors to ensure that HVAC systems, electrical distribution, plumbing layouts, and structural elements all fit together efficiently and meet South Carolina building codes. They also prepare construction documents and specifications that contractors use to bid on and execute the work.
Key Takeaways
- Architectural engineers design and coordinate mechanical, electrical, plumbing, and fire protection systems alongside or instead of a structural frame, making them different from structural engineers who focus only on load-bearing capacity.
- South Carolina requires architectural engineers to hold a PE license, which involves passing the FE exam, accumulating work hours under a licensed engineer, and passing the PE exam in architectural engineering.
- You typically hire an architectural engineer during the design phase of a project, before construction begins, so they can integrate all building systems into the plans and specifications.
- Architectural engineers prepare construction documents that contractors use to bid on work and that building inspectors use to verify code compliance during construction.
When to hire an architectural engineer for your project
Hire an architectural engineer early in your project planning, ideally during the conceptual or schematic design phase. At this stage, they can influence how the building layout, structural system, and mechanical systems work together—changes made later cost more money and time. If you're renovating an existing building in South Carolina, an architectural engineer can assess whether the current systems can support your new use or whether upgrades are necessary to meet current code.
You do not need an architectural engineer for every project. A small residential addition or a straightforward commercial tenant improvement might only need a structural engineer and an architect. However, if your project involves complex mechanical systems, significant electrical loads, multiple floors, or adaptive reuse of an older building, an architectural engineer's coordination role becomes valuable. They reduce conflicts between trades and catch design problems before they reach the construction site.
How architectural engineers differ from architects and structural engineers
An architect designs the building's appearance, layout, and user experience. A structural engineer designs the frame and foundation to safely carry loads. An architectural engineer typically designs the systems that run through the building—HVAC ducts, electrical conduit, plumbing risers, fire sprinkler lines—and coordinates those systems with the structure and architectural layout. Some architectural engineers also design the structural frame, but many work alongside a structural engineer rather than replacing one.
In practice, the three professions overlap. On a small project, one person might hold both architect and engineer licenses. On a large project, all three work together, with the architectural engineer often acting as the coordinator who ensures that the architect's vision, the structural engineer's frame, and the mechanical contractor's equipment all fit in the same building without conflicts.
South Carolina licensing and credentials
To practice as an architectural engineer in South Carolina, a person must hold a PE license issued by the South Carolina Department of Labor, Licensing and Regulation (SCDHEC). The path to licensure includes a four-year engineering degree (or equivalent), passing the Fundamentals of Engineering (FE) exam, working under a licensed PE for a set number of years (typically four years for someone with a degree), and passing the Professional Engineer (PE) exam in architectural engineering.
When you hire an architectural engineer, ask to see their PE license and verify it through the South Carolina SCDHEC website. A licensed architectural engineer has met state standards for education, experience, and testing. Some firms employ engineers who are not yet licensed but work under the supervision of a licensed PE; that arrangement is legal, but the licensed PE is responsible for the work's quality and compliance.
What architectural engineers deliver on your project
An architectural engineer produces a set of construction documents that include plans, sections, details, and specifications for all building systems. These documents show contractors where to run ductwork, route electrical circuits, install plumbing, and connect fire protection equipment. The documents also include calculations and notes that explain the design choices and confirm compliance with South Carolina building codes.
During construction, the architectural engineer may visit the site periodically to observe that the work matches the plans and specifications. They answer questions from contractors, issue clarifications or change orders when needed, and prepare a final report confirming that the systems are installed correctly and ready for operation. Some architectural engineers also commission the building systems—running them through a series of tests to ensure they perform as designed before the building opens.
Finding and hiring an architectural engineer in South Carolina
Start by asking your architect or structural engineer for a recommendation. If you don't have either yet, contact the South Carolina Council of Engineering and Surveying Societies (SCCESS) or the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) South Carolina chapter for referrals. You can also search the SCDHEC licensing database to find licensed architectural engineers in your area and review their credentials.
When you contact a firm, describe your project scope and ask whether they have experience with similar work. Request references from recent projects and ask those clients about the engineer's responsiveness, communication, and ability to stay on budget and schedule. Get a written proposal that outlines the scope of work, the fee structure (hourly, fixed fee, or percentage of construction cost), and the timeline. Make sure you understand what is and is not included—for example, whether the fee covers site visits during construction or only the design phase.
Cost and timeline for architectural engineering services
Fees vary widely depending on project size, complexity, and location within South Carolina. A small renovation might cost a few thousand dollars; a large commercial building could cost tens of thousands. Some firms charge an hourly rate (typically $100 to $250 per hour for a licensed PE), others charge a fixed fee for the entire project, and some charge a percentage of the total construction cost (often 2 to 5 percent). Ask multiple firms for proposals so you can compare.
Timeline depends on project scope. A straightforward design might take four to eight weeks from start to finished construction documents. A complex project with multiple systems and code reviews can take three to six months or longer. The architectural engineer's schedule also depends on how quickly you and other team members provide feedback and decisions. Build in time for code review by the local building department before construction begins—this can add two to four weeks to the overall timeline.
Frequently Asked Questions
Do I need both an architect and an architectural engineer?
Not always. For a simple project, an architect alone may be sufficient. For a complex building with many mechanical and electrical systems, both are valuable because they bring different expertise. An architect focuses on design and user experience; an architectural engineer focuses on how systems integrate and function. Your project scope and budget will determine whether you need both.
Can an architectural engineer design the structural frame?
Yes, many architectural engineers are trained and licensed to design structural systems. However, some specialize in building systems only and work alongside a structural engineer. When you hire an architectural engineer, ask specifically whether their scope includes structural design or whether you will need a separate structural engineer.
What happens if the architectural engineer's design doesn't match the building code?
The local building department reviews the plans before construction begins and will reject them if they don't meet code. The architectural engineer then revises the design and resubmits. This is why it's important to hire a licensed, experienced engineer—they know the codes and can design correctly the first time, avoiding delays and extra fees.
How often does the architectural engineer visit the construction site?
This varies by contract. Some contracts include regular site visits (weekly or monthly); others include only occasional visits or none at all. Clarify this in your written agreement before work begins. Regular site visits help catch problems early, but they also add to the fee. Discuss with your engineer what level of site observation makes sense for your project.
Can I use the same architectural engineer for multiple buildings?
Yes. If you own or manage multiple properties in South Carolina, you can develop an ongoing relationship with an architectural engineer who becomes familiar with your standards and preferences. This can speed up future projects and reduce costs because the engineer won't need to learn your requirements from scratch each time.
