Approve proposal from Shenandoah Construction, Inc. in the amount of $20,900.00 for an emergency drainage repair required for an outfall through a seawall located at 1705 Sunset Isle Road.

The existing 18" RCP drainage pipe which conveys stormwater run-off from Sunset Isle Rd, Bayshore Drive, and Plover Avenue roadways has failed and is in need of emergency drainage repair. Sink holes have developed behind the seawall as a result from joint separation in the drainage outfall pipe.  This section of the drainage system has been televised and inspected by the Engineering Department (attached report and pictures) and it was determined the existing pipe could be lined to prevent further erosion.

The scope of work includes the de-watering, cleaning and installation of an 18” cured in place liner, seawall repair and site restoration.
 

Due to the severity of the erosion behind the seawall, emergency work was authorized prior to City Commission approval.  Staff is requesting after-the-fact approval prior to payment to the contractor in the amount of $20,900.00.

Circumstances warranted emergency repair.
