Their work typically includes site assessment, structural design, construction administration, and coordination with other trades involved in a project.

Key Takeaways

• Dennis Corporation provides structural design and engineering consultation for new construction and renovation projects throughout South Carolina.
• The firm works across residential, commercial, and industrial building types, collaborating with architects and contractors on each project.
• Structural engineers like Dennis Corporation ensure buildings meet South Carolina building codes and safety standards before construction begins.
• Project timelines and costs depend on the scope of work, building complexity, and whether the project involves new construction or existing structure modifications.

Types of Projects Dennis Corporation Handles

Structural engineering applies to nearly every building project. Dennis Corporation's work may include single-family homes, multi-unit residential buildings, office parks, retail centers, warehouses, manufacturing facilities, and renovation or adaptive reuse projects that require structural assessment and redesign.

For new construction, the structural engineer develops the framework—foundation systems, load-bearing walls, steel or concrete framing, and connections—that holds the building up and distributes weight safely to the ground. For existing buildings, structural engineers assess conditions, identify problems like settling or deterioration, and design repairs or modifications.

How Structural Engineering Fits Into Your Project Timeline

Structural engineering typically begins during the design phase, before construction starts. An architect or owner contacts the structural engineer with project goals and site information. The engineer then produces drawings and calculations that become part of the construction documents contractors bid on and build from.

Once construction begins, the structural engineer may visit the site periodically to confirm that work matches the design and that materials meet specifications. This phase, called construction administration, helps catch problems early and keeps the project aligned with the engineer's intent. The total timeline from initial consultation to final sign-off varies widely depending on project size and complexity.

Working With Dennis Corporation on Your Project

If you are planning a building project in South Carolina, the typical first step is to contact Dennis Corporation with a description of your scope—whether you are building new, renovating, or assessing an existing structure. Provide site information, budget constraints, and timeline expectations so the firm can determine whether they can take on the work and give you a sense of fees and schedule.

Structural engineering fees are usually quoted as a percentage of construction cost, a fixed fee for the project, or an hourly rate, depending on the firm's practice and the project type. Discussing fees upfront helps you budget for this phase of design work. Many projects also require permits from the local building department, and the structural engineer's drawings and calculations form part of the permit application.

South Carolina Building Codes and Structural Requirements

South Carolina follows the International Building Code (IBC), which sets minimum standards for structural design, materials, and construction methods. Structural engineers like Dennis Corporation use these codes to determine how strong a building's frame must be, what materials are acceptable, and how to protect occupants from hazards like wind, earthquakes, and fire.

Coastal South Carolina has additional requirements because of hurricane risk and salt-air corrosion. Engineers working near the coast must account for higher wind speeds and may specify corrosion-resistant materials or special foundation systems. The local building department reviews structural plans before issuing a permit, so compliance with these codes is mandatory before construction can begin.

When You Might Need a Structural Engineer

You need structural engineering for new construction projects of any significant size. You also need it when adding to an existing building, removing walls, installing large openings, or changing how a building is used—for example, converting a warehouse to apartments or adding a second story to a house. Structural assessment is also necessary if you notice cracks, sagging, or water damage that suggests the building frame is failing.

Smaller residential projects like decks, sheds, or minor renovations may not require a structural engineer if they follow standard prescriptive codes, though local building departments vary in their requirements. Checking with your local building department before starting design work tells you whether structural engineering is required for your specific project.

Frequently Asked Questions

How much does structural engineering cost?

Fees vary based on project complexity, size, and the firm's pricing model. Some firms charge a percentage of construction cost (typically 1 to 3 percent), others quote a fixed fee, and some bill hourly. Contact Dennis Corporation with your project details to receive a fee estimate specific to your work.

How long does structural design take?

Timeline depends on project scope and complexity. A simple residential project might take a few weeks; a large commercial building could take several months. Discuss your schedule with the engineer early so they can confirm whether they can meet your timeline.

Do I need a structural engineer if I'm just renovating?

It depends on the scope. If you are removing walls, adding openings, or changing how the building is used, structural engineering is usually required. Minor cosmetic renovations typically do not need it. Your local building department can tell you what is required for your specific project.

What happens if the structural engineer finds a problem with my existing building?

The engineer will document the issue and recommend repairs or modifications. You then decide whether to proceed with those repairs, get a second opinion, or address the problem differently. The engineer's job is to identify the problem and propose solutions, not to force any particular outcome.

Can a structural engineer help with permitting?

Yes. Structural drawings and calculations are required documents for most building permits. The engineer typically submits these as part of the permit package or works with your architect or contractor to do so. Some firms handle the entire permit process; others provide only the structural documents.
