LHC Structural Engineers

Building Information Modeling (BIM)

LHC Structural Engineers understands that building design and construction is moving away from fragmented and cumbersome processes to more integrated and streamlined delivery methods. We embrace the production management concepts adopted by the manufacturing industry known as “lean construction” and “integrated project delivery”.

N.C. State University Wolfpack Sculpture

Even before today’s software tools were developed we were working with the concepts of BIM. Most notably was our work for the Wolfpack sculpture at NC State’s Carter Finley Stadium.

The artist’s bronze sculpture was used to build a scaled plaster model that was taken to Whitworth & Associates in Lexington, South Carolina for a series of 3-D laser scans.

The laser scan information was translated into two dimensional topographic contours at 4 inch intervals and provided to LHC in a format that could be imported into Autocad.

The contours allowed us to build a three-dimensional model where we could insert tube steel framing and pedestals to provide permanent structural support to the sculpture. The steel framing design was then prepared in two-dimension drawings for fabrication.

LHC's Approach

Today we are adept at integrating documentation models in AutoCad or Revit with design and analysis models in RAM or RISA. But we know that BIM projects involve much more than the utilization of latest software tools.

Successful projects are a team effort where the structural frame is integrated and coordinated with all design disciplines and building trades. We particularly invest our time early in a project where strategic decisions and design ideas have the most impact on the final product. Through model sharing and team dialog, we encourage coordination and clash detection efforts with designers and we welcome constructive input from building trades in design assist roles.

We provide the final model to all interested parties for use in fabrication and construction and are equipped to conduct paperless submittal review with steel fabricators.

Leading the Way

Rob Stevenson has led three projects where the RAM Structural System Model was maintained and distributed to two parties, the design team model manager for coordination and the structural steel detailer for fabrication.

Mr. Stevenson has been an active participant in the E-Commerce Roundtable, organized by AISC annually at the national convention. He presented at the North Carolina Construction Conference in 2009.
