City of Frederick Wastewater Treatment Plant


The City of Frederick Wastewater Treatment Plant project consisted of the expansion of the existing City of Frederick facility which included the construction of two (2) new, large clarifying tanks.


Specialized Engineering was responsible for Subsurface Investigation to determine the conditions of the site prior to excavation, Environment Consulting, and the monitoring Construction Quality Assurance/Quality Control (QA/QC) during the phases of construction.

Specialized Engineering determined that the subsurface material was unsuitable for structural fill as previously anticipated. The unsuitable soil was considered to be environmentally contaminated and required special disposal at a certified location. Specialized Engineering prepared the required environmental documentation, testing, and monitoring to ensure the proper disposal of contaminated soil.

Testing and Inspection Services provided by Specialized Engineering included the following:

  • Structural Backfill/Fill
  • Reinforcing Steel
  • Structural Steel
  • Formwork
  • Concrete Pre-Placement
  • Cast-In-Place Concrete

Specialized Engineering conducted laboratory testing and analysis of proposed fill materials, testing of concrete cylinders, and soil sampling. Wish to learn more about our involvement with this project? Please contact us at 800-773-3808.
