Considerations for the Future of Consulting Structural Engineering 
What will the consulting engineering and structural engineering profession look like in 10 years?  Have you contemplated the impacts of changes in licensing, technology, contracts, employment trends, and other areas on the profession and business of engineering?  No one has a crystal ball with all of the answers but if we want to survive and thrive in the future, we need to be investing time and energy into considering the answers and directing our own future.  I will share some of my thoughts and observations based on my role as a structural engineer, business leader, professional organization leader, and founding member of the Engineering Change Lab USA which is dedicated to this topic.  Plan to engage in a dialog and share your own thoughts and insights.

Aire Ancient Baths Chicago
Rarely does a project have the entire structure so elegantly exposed and intertwined with the architecture.  Aire was a challenging 20,000 square foot renovation of the first two levels of an existing eight-story, heavy timber, and masonry old factory structure.  The interior work required adding and removing floor framing, installing new stairs with a hanging walkway, and inserting new pools between existing shallow foundations.

Lessons Learned: Delegation of Engineering Design and Communication of Construction Sequencing
Thornton Tomasetti
Delegating the design of structural components is easy to do and saves time and effort for the Engineer of Record, especially in these days of competitive design fees - doesn’t it?

The author will outline the pitfalls to avoid when delegating the design of structural components such as precast concrete, stairs, structural steel connections, pre-engineered buildings, cold formed steel, and similar materials and components, using an actual project as an example.

Certain jurisdictions prescribe minimum amounts of information to be provided by the Engineer of Record to the Delegated Engineer.  Where is the line drawn between the role of the EoR and the role of the Delegated Engineer? What are the consequences to the cost and schedule of the project if this delegation is not properly executed?

On a similar note, when and where does the responsibility lie for the EoR to communicate construction sequence to the building department and contractors? Is it only relevant where design assumptions or the construction are extraordinary? Or does the EoR need to communicate the requirement of one structure bearing on another, for example, which may be obvious from the drawings and would consequently dictate the logical construction sequencing? How about the effects of sheltering from the wind and whether your building can take advantage of such circumstances? Or can all of this be handled through the construction administration process?

In this session, the authors just don’t ask the questions – they answer them too!

Stick Framing - Achieving New Heights
Mid-rise buildings typically default to steel or reinforced concrete structural systems, yet recently, pre-fabricated, light-gauge metal, load-bearing wall systems are becoming a strong contender in the residential and hospitality markets. With proper planning, these systems can be used in buildings up to 12 stories tall. During this presentation, we will review the application of these light-gauge wall systems and discuss their fabrication and installation. We will also explore some of the benefits of these systems, including minimal floor-to-floor height, reduction in fireproofing, and lower overall structural system cost.



Christine Freisinger, SE, PE, Associate Principal
Wiss, Janney, Elstner Associates
Christine Freisinger is an Associate Principal at Wiss, Janney, Elstner Associates, Inc. in the Chicago office where she has worked as a structural engineer since 2004, primarily focusing on the investigation, evaluation and repair of existing structures.

Making New Welds to Existing Steel - Part 1: Assessing the Existing Steel
A tenant renovation project in Chicago included a monumental stair that required removal of four bays of clay tile arch floor slab supported by steel framing, reinforcement of built-up steel columns, and installation of new steel stair framing. The original building was constructed in 1905 and required careful consideration for the connections of the new steel to the historical steel, which was manufactured to an uncertain specification. Steel tensile properties testing and metallurgical examination, including metallography, were required to understand the properties of the historical steel and to assess the propensity for lamellar tearing of the steel where welded. 



Conrad Paulson, Principal

Conrad Paulson is a Principal in the Los Angeles (Pasadena), California office of Wiss, Janney, Elstner Associates, Inc. (WJE). He has worked as a structural engineer at WJE for more than 38 years, having spent more than 25 years in the downtown Chicago office, where he focused on the investigation, evaluation, and repair of historical structures of all types. He has been in the WJE Los Angeles office since 2013, now primarily focusing on seismic-related evaluation and retrofit of existing structures, although still routinely involved with historical buildings. He is a member of numerous technical committees, including AISC Committee on Specifications, Chair of AISC Task Committee 7 - Evaluation and Repair, and ACI 318 B, Structural Concrete Building Code: Subcommittee on Reinforcement and Development.



Making New Welds to Existing Steel - Part 2: Welding Considerations for Existing Steel
A tenant renovation project in Chicago included a monumental stair that required removal of four bays of clay tile arch floor slab supported by steel framing, reinforcement of built-up steel columns, and installation of new steel stair framing. At the time that this building was constructed in 1905, the ASTM Standards were not yet widely accepted, making it difficult to identify the specific standard that was used to produce the steel. For welded connections, the structural engineer is confronted with specifying welding requirements for structural steel that was manufactured to an uncertain specification.

Lighten Up! – Lowering Embodied Carbon in Design and Construction
Today we are at a tipping point where how we design, and the materials we specify, are under increasing pressure to be more climate friendly. Client and public demand for a more responsible and climate friendly built environment is growing, and structural engineers play a significant role in how or if this happens. This presentation will critically look at how Life Cycle thinking can influence how we approach our design challenges to be more climate focused. It will also highlight a number of opportunities where the structural engineer can help drive value to our clients who are now prioritizing lower carbon construction.

Benton’s project experience includes a range of domestic and international projects, from supertall buildings, mixed-use developments, and commercial offices, to convention centers, healthcare facilities, and demonstration buildings.

A Tower and a Bridge - Structure as Architectural Expression
Two recently completed projects are functionally quite different but share many similar characteristics. With these two projects, the structural systems are developed to efficiently respond to the unique aspects of the projects, and this is expressed as part of the architecture. From the overall form to careful attention to detail, these two projects are explored.
