LHC Structural Engineers

Building Facade & Attachment Design

LHC believes in an integrated approach to building design. The structural engineer’s responsibility does not stop at the beam or slab edge. Rather, he must collaborate with the architect to develop simple and elegant solutions to cladding designs and attachments to building frames and foundations

Precast Concrete & GFRC Panels

Precast panels can be hung from the frame or stacked from the foundation, sometimes doubling as structural shear walls. Communication between LHC and the precast engineer can streamline and economize wall system design.

Curtain Wall

Mullion framing is stick built like any structural framing system. Walls can accommodate a variety of framing arrangements, especially when the curtain wall structural engineer collaborates with LHC’s building frame structural engineer.

Stone Veneer

This specialty material requires that the structural engineer understand material properties, wall system components, attachment techniques and construction tolerances.

Metal Panel

Metal panel façades backed up with metal stud or structural steel framing, designed by the metal panel contractor or by the project structural engineer. Both options require input and collaboration on the part of the structural engineer.

Brick Veneer

Besides designing relief angles, the structural engineer can assist with developing expansion and control joint layouts or he can help address special challenges like interfaces with other cladding systems or unique lintel solutions.

Masonry Back-Up

Brick and other cladding materials often rely on masonry walls for vertical and lateral support. The masonry wall must be engineered to carry imposed loads and to improve wall performance in terms of durability and serviceability.

Steel Stud Back-Up

Steel studs are typically engineered by the contractor to support the cladding system. It is crucial that the structural engineer thoroughly communicates assembly details, attachment concepts and design criteria.


Like curtain walls, skylights are designed and fabricated as complete systems by the supplier. The structural engineer must work with the supplier to develop a suitable supporting framework that accommodates the system requirements.
