Summary:
Summary
Change Order No. 1 is to address unforeseen subsurface conditions, underground infrastructure conflicts and deterioration. Highly variable ground conditions, including unsuitable materials (cypress trees/stumps and debris), were discovered during construction. These conditions could result in premature structural pavement failure if not corrected. County staff worked with the contractor and the consultant engineer to conduct extensive field investigations, including twelve (12) additional test holes to validate soil conditions and existing pavement base thickness. The remediation plan consists of utilizing eleven inches (11”) of recycled crushed concrete as roadway base in lieu of the reworking of the variable shell base material. Due to these findings a price increase and additional days are required to be added to the contract.
