John Humphrey Complex Renovation - V3 Contract Extension
History
On March 18, 2019, the Village Board approved V3 Construction Group’s (V3) contract for the John Humphrey Complex (JHC) Renovation. The approved contract value was $1,608,377.
Geotechnical samplings of the JHC were discussed between Village staff and V3 in order to identify soil conditions that would assist the team in defining a longer term solution, especially settlement issues at Field 3. The geotechnical sampling and resulting soil improvements were not included in the original contract scope and costs.
Geotechnical Study
Geotechnical samplings were collected and studied in the month of April and the results were reviewed by V3 and Village staff. The following is a summary of the Geotechnical Study:
1. Miscellaneous fill material was identified throughout the sports complex. Some of the soil borings indicate loose, organic fill and buried topsoil that will require removal and replacement and/or disking and drying during the mass grading operation. The majority of these areas can be addressed through typical grading operations and will not require specialty mitigation measures for completion of the proposed improvements.
2. Groundwater was encountered at depths ranging from 5.5 feet to as deep as 17.0 feet below existing ground surface.
3. Field 3 - very soft and wet peat was encountered in the outfield that will require consideration.
4. Field 3 - peat was encountered at depths ranging from approximately 8 feet to 13 feet below existing ground surface and extending to 22 to 27 feet below existing ground surface.
5. The existing conditions of Field 3 show significant grade differential from the outfield to home plate. The timeframe over which this perceived settlement has occurred has not been confirmed. Typically, the majority of settlement occurs shortly after the load is imparted on the soft soils and a decreasing amount of settlement is experienced over time. Peat...
