In January 2023, during routine geomembrane liner repair work on the south side slope of M4P1, Geosynthetic Clay Liner (GCL) panel separation was observed. GCL panel separation has since been identified in multiple locations, and the County is contracting to repair the areas where GCL separation exists.

The County is repairing the liner system in stages, and as such, has not performed a complete survey of the areas where the GCL separation has occurred. An estimate of the anticipated scope of work (Work), including number of seams and average seam length are included for bidding purposes.

TERM

This Agreement shall be effective and commence as of the date of execution and shall remain in effect until June 30, 2024

Basis for Award

This bid award will be determined by the lowest responsive and responsible bid by a qualified Bidder, as defined in Attachment B, Installer Company and Minimum Qualifications.
