SC2 / geotechnical and structural instrumentation and monitoring during construction
INSTRUCTOR: Malay Ghose-Hajra, Ph.D., P.E., ENV SP, M.ASCE, The University of New Orleans
Depending upon the natural processes of geologic formation, previous stress history at the project site, and activities at adjoining properties, the geotechnical and structural engineers of design are often challenged with a wide variety of naturally occurring heterogeneous materials below ground and several unknown parameters that need to be accounted for in their analysis and design recommendations. Unlike design of concrete or steel structures, where most material properties are specified and manufacturing is controlled, mineralogical composition, particle arrangement, and engineering properties of soil and rock can vary significantly in the vertical and horizontal directions within a short distance. Adequate instrumentation of subsurface soil and superstructures can provide engineers with valuable performance benchmarks during every stage of a project. Strategically placed instruments can be used to characterize initial subsurface site conditions, verify design assumptions, and provide data for use in quality control during construction; as well as give early warning of impending failures, thus saving valuable life and project cost.
This short course will focus on new and emerging instrumentation and monitoring techniques and procedures, case studies, and lessons-learned presentations. Attendees will learn about:
- Soil properties affecting geotechnical and structural instrumentation and field monitoring principles
- Systematic approach to geotechnical and structural instrumentation
- Geotechnical and structural instrumentation hardware
- Field measurement of groundwater pressure, deformation, stresses, load and strain
- Remote monitoring and automatic data acquisition
Upon completion of this course, participants will be able to:
1. Describe and explain the benefits of geotechnical and structural instrumentation and field performance monitoring systems.
2. Identify and design a geotechnical or structural instrumentation program for a specific project.
3. Accumulate, process, interpret, and report field data collected from a geotechnical and/or structural instrumentation system.

INSTRUCTORS: Jon‐Paul Cardin, P.E., M.ASCE, Construction Codes and Standards Engineer, American Iron and Steel Institute; Cristopher D. Moen, Ph.D., P.E., M.ASCE, Virginia Tech
Cold‐Formed Steel (CFS) is one of the most common materials utilized in commercial construction. However, since CFS design is not a subject that is included in most engineering curriculums, most structural engineers are often left with very minimal understanding of basic design concepts. Therefore, a large portion of CFS design for most structural engineers revolves around the product information published by the manufacturer. The course instructors will provide the participant with an exclusive perspective into all aspects of the CFS industry:
- Mr. Cardin managed the engineering department for a large cold-formed steel framing manufacturer up until 2015. As such, he served as the direct contact for structural engineers with respect to technical/design questions regarding CFS.
- Dr. Moen is on the forefront of the cold‐formed steel industry with respect to research, innovation, and code development. As a professor at Virginia Tech University he educates and guides the future engineers in the CFS industry.
Upon completion of this course, participants will have:
1. Developed a working comfort level with CFS design
2. Acquired thorough knowledge of standard CFS framing members and connectors.

INSTRUCTORS: Geoff Chao, Ph.D., P.E., M.ASCE, Vice President, Engineering Analytics, Inc.; Daniel D. Overton, P.E., F.ASCE, Principal Geotechnical Engineer, Engineering Analytics, Inc.
Foundations on expansive soil sites are one of the most challenging problems facing geotechnical and structural engineers, builders, and building owners today. Many of the problems result from failure to identify expansive soils on the sites, inadequate design and construction, use of inappropriate foundation systems, and/or improper construction practices. Increasing basic knowledge of soils engineering is the key to identifying design and construction defects for structures on expansive soils.
An important part of the engineering is the selection of an appropriate foundation type for structures on expansive soils. For sites with highly expansive soils, more robust foundation types are necessary than those used for soils exhibiting lower expansion potential. The most reliable foundation type that is commonly used for sites on moderate to highly expansive soils consists of a drilled pier foundation supporting a grade beam, with a structural floor.
This short course is intended to provide geotechnical, structural, construction engineers, and engineering geologists with the knowledge and tools necessary to design the pier foundation in expansive soils. Computer programs SVHeave and APEX developed by SoilVision Systems Ltd. will be utilized to assist in the design process. This course will include the following topics:
- Nature of expansive soils
- Site investigation
- Laboratory testing for expansive soils
- Water migration in expansive soils
- Heave prediction methods
- Design of pier foundation
Upon completion of this course, participants will:
1. Understand the site investigation and laboratory testing that need to be included when designing the pier foundation in expansive soils
2. Be able to correctly apply heave prediction methods to the design of the pier foundation and avoid pitfalls
3. Have the knowledge and tools necessary to design the pier foundation in expansive soils
4. Understand the utilization of computer programs to assist in the design process
