Services
New Construction
Our new construction services encompass comprehensive structural design from schematic phase through construction administration. We specialize in diverse foundation types, including hydrostatic basements and pile-supported systems, and employ multiple structural materials such as steel, concrete, and engineered wood. Our team provides full code compliance documentation and special inspections administration for municipal, commercial, and residential projects ranging from educational facilities to high-end residences.
Structural Investigations
TDEG's structural investigations include comprehensive evaluations of buildings, parking structures, and small bridges for damage assessment, code compliance, and pre-purchase analysis. Our team conducts detailed reviews of structural systems affected by weather events, overloading, or aging, providing remedial design recommendations that balance safety requirements with cost-effective solutions while meeting current building code standards.
Additions & Renovations
We offer complete structural solutions for building modifications, including adaptive reuse projects that repurpose existing structures for new functions. Our services cover existing system verification, structural analysis for new loads, and code compliance assessments for the International Existing Building Code. From minor renovations to full-scale additions, we ensure seamless integration of new and existing structural components across multiple material types.
Specialty Engineering
Our specialty engineering services focus on providing design solutions for temporary and permanent construction elements not addressed by primary design teams. This includes secondary steel systems, monumental stair design, foundation underpinning, and crane rigging plans. We deliver practical, code-compliant solutions for complex construction challenges that require immediate implementation during project execution phases.
Adaptive Reuse
TDEG specializes in adaptive reuse projects that transform existing structures while maintaining their historic integrity. Our work includes structural system upgrades to meet modern code requirements, change-of-use assessments, and FEMA compliance improvements. We provide analysis of existing components and design seamless integration of new structural elements while preserving architectural character in commercial to residential conversions and other reuse scenarios.
