TEG Engineering provides specialty precast engineering for architectural and structural precast concrete. We have completed designs for primary, intermediate and secondary schools with combined safe rooms (ICC-500/FEMA P-361), emergency communication centers, commercial and industrial buildings, as well as hospitals and parking garages. Design submittals have included architectural cladding, thin brick applications, composite and non-composite structural precast, insulated and non-insulated wall panels, special reinforced concrete shear walls, prestressed double tee beams, columns, spandrels, stairs, shear walls and lite walls.


Precast Structural Systems (Total Precast Systems)

Precast concrete is a structural material that can be used as the primary structural system of a building transferring roof, floor, and lateral loads. Precast enables designers to integrate structural and envelope (architectural) systems reducing the total materials, detailing, costs, construction complexity and more. Sometimes, this is referred to as "Total Precast Systems, or TPS.

The design versatility of precast concrete allows for almost any shape element such as curved and radial sections, with flexibility in connection points and load paths. High strength, prestressed concrete structural members also deliver exceptional load-carrying capacity, which can result in smaller sections, longer spans, or both when compared to other structural systems.

Total Precast concrete offers many benefits

  • Combines architectural and structural concrete into one element
  • Eliminate redundancy of creating separate systems for structural loading and cladding support
  • Can be manufactured and erected more efficiently and quicker than other building systems
  • Quicker occupancy
  • Eliminates the need for cementitious fireproofing and the associated costs and scheduling impact of insulated curing blankets and temporary heat

  • Variety of exterior finishes and wide range of shapes
  • Durability and Sustainability. Precast concrete can contribute significantly toward a green-building rating.

Precast Concrete Wall Systems

Precast concrete wall systems can be comprised of a variety of shapes, and wall types. Typically, precast concrete wall systems fall into three basic categories: solid, sandwich and thin-shell. These can be panelized and erected in either a horizontal or vertical position and used on all types of structures from residential to commercial, institutional to industrial. Wall panels can be designed as nonloadbearing or loadbearing, carrying floor and roof loads, as well as lateral loads.

Types of precast concrete wall systems:

  • Solid Walls
  • Sandwich Walls
  • Thin-Shell and GFRC
  • Lite Walls

Similar to the design-build delivery methodology often used by owners, design-assist procedures offer key benefits which can save a significant amount of time, money and changes on a project. As a design-assist partner, TEG specializes in working with precaster’s at the earliest stages of the design process to help provide the most efficient methods, sizes, aesthetics, etc. to maximize efficiency throughout the project and meet the owner’s goals and financial requirements.

Early involvement in the design process provides an opportunity to value-engineer aspects of the structure and allows us to make recommendations toward a design that may reduce risk, reduce lead times, and ultimately reduce costs. Using BIM to provide 3D project models, TEG can coordinate with precaster’s and use their expertise and efficiencies to conduct constructability reviews and give advice for component design, fabrication, erection, lifting and handling as needed.

Through collaboration with the precaster, TEG will serve as the specialty precast engineer and provide assistance to the owner’s A/E design team in the form of preliminary drawings, connection details, erection logistics and other specific project information, based on the A/E’s building concepts and structural system. TEG will participate in regular communication with the A/E design team during the design development and throughout the completion of 100% Construction Documents. This process improves the flow of information and drawing approval once shop drawings begin.
