Our Qualifications


Geotechnical Instrumentation

Our geotechnical engineering team will help you design and execute your project with safety and economy. We will guide you in the selection of the proper instrumentation program to confirm design assumptions, determine initial or background conditions, and monitor the safety of a structure or construction operation.

Foundation Analysis and Design

Foundation type, load-carrying capacity, long-or short-term foundation movement under the expected loading — these are the design issues that Wang’s highly qualified engineers tackle daily. Our goal is to find the budget-conscious foundation system that will perform according to the stipulated critera. Our extensive project experience includes:

  • Building
  • Bridge
  • Drainage
  • Embankment
  • Earth Retaining Structures

Ground Improvement and Treatment

Wang can select and design viable and economic in-situ mitigation solutions for project sites with poor or unstable soil conditions. Our project experience includes:

  • Cut and fill
  • Load balancing
  • dynamic compaction
  • prefabricated vertical drains
  • stone columns
  • geopiers
  • micropiles
  • soil nailing
  • geosysntehics

We can also assist with writing project specifications, performing QA during construction, and monitoring post-construction performance.

Project Experience

In the transportation sector, our geotechnical project experience encompasses interstate, federal, and local highways and streets, rail and rapid transit facilities, and airports. Wang’s geotechnical work also covers foundation design for public, commercial, and industrial buildings, including schools and universities, commercial and recreation centers, and water and wastewater treatment plants. In addition, we provide infrastructure-related geotechnical and testing services to local municipalities. 


We are prequalified to provide complete geotechnical engineering consulting to the state transportation authorities of Illinois, Indiana, Iowa, Kentucky, and Ohio, including geotechnical drilling, laboratory testing, foundation analyses and evaluation, and comprehensive engineering reporting and recommendations. In recognition of our capabilities, Wang has been selected as IDOT District One’s Geotechnical Consultant in 2008, 2006, 2000, and 1994.

We have completed numerous major projects throughout the Chicago area for various public agencies.
