  • WACEL has been tapped by Prince George’s County to help it revamp it's Third Party Inspection Program.  On Friday, December 9, 2018, we were represented at the inaugural meeting of this effort. County officials informed us that the legal department is requiring the Department of Inspections to obtain a signed copy of Attachment 5 of the existing TPIP Program in order to sign off on projects.  We realize that almost no one has ever signed Attachment 5 in the past, but moving forward for the time being you will have to submit Attachment 5Attachment 5 is the final inspections report and Attachment 6 is the Third-Party Inspection Program Certification Form.  Both are now required until the update to the TPIP program has been completed.


  • The WACEL Board of Directors voted on during the April meeting to require the Soils I Field Practical to be submitted prior to taking the written exam.  This is effective August 1, 2018.

WACEL Membership Meetings

Plan now to attend upcoming WACEL Membership Meetings.  The April 25th meeting topic is Five Ways to Improve the Cost and Performance of Ground Improvement for Foundation Support Projects.  The presenter will be Michael Cowell, P.E. - CEO and President of GeoStructures, Inc.

Specifying an aggregate pier or rigid inclusion ground improvement foundation support system can save a significant amount of money versus an over excavation or deep foundation option for building projects.  However, some of this money can be left on the table if the specification is not accompanied by a good baseline geotechnical and structural engineering package, site specific design requirements, specific contractor qualification requirements, a clear scope of work, QC requirements and a measurement and basis of payment requirement.

The talk will discuss some of the common practices that need to be changed that can add cost and risk to a project and highlight areas of best practices which can lower costs, risk and provide clarity to a ground improvement design-build project.

Attendees will receive one-hour Continued Education Credit (CEU) for attending this presentation.
