Attached for your review and consideration for approval is the final pay request from Layne Inliner, LLC, in the amount $55,000.00 for stormwater drainage pipe rehabilitation.  The pay requests includes the same conditions and unit pricing as the current Pinellas County ITB#134-0252-CP.  The usage of this contract and pricing is in accordance with the City's purchasing procedures and guidelines. As City Council may recall, this project was approved by City Council at a regularly scheduled meeting held on November 15, 2016.

Subsequent to Stormwater Utility maintenance staff pipe inspections, severe deterioration of existing stormwater drainage pipes were identified in the Woodridge and Tropic Shores subdivisions. The existing stormwater pipe materials were reinforced concrete and corrugated metal material.  The reinforced concrete pipe contained extensive cracking due to subsurface hydraulics.  The corrugated metal pipes were rusted beyond repair.  Each of these conditions resulted in infiltration of water and sand and had the potential to damage streets and right of ways if not corrected.  The pipe lining type of rehabilitation method has a considerable reduction in cost from traditional pipe laying construction because it eliminates the cost of restoration and allows the existing facilities to remain in place with no disruptions to the general public.
