Deadline: 12/17/2020 2:00 PM   (UTC-05:00) Eastern Time (US & Canada)

Status: Awarded

Solicitation Number: 36319

Description:

Rehabilitate the following culverts by sliplining using a continuous high-density polyethylene (HDPE) pipe culvert sleeve inserted into existing culvert with a low-density cellular grouting application. See attached Map 1 for general locations of each culvert.

S-6A is a gated culvert comprised of one barrel, extending southwest (gated end) to northeast under Levee L-75, which is an earthen levee with limerock capped driving surface on top. The barrel is a CMP, 48 inches diameter by 102 feet long. The southwest end has an access pier comprised of a concrete T-beam superstructure supported by a buried concrete abutment and the concrete gate box. There is a gate at the upstream end. See Map 2 for an aerial view of this culvert.

S-252A is a gated culvert comprised of two barrels, extending south (gated end) to north under Levee L-78, which is an earthen levee with limerock capped driving surface on top. The barrels are CMP, 60 inches diameter by 126’ feet long. The south end has an access pier comprised of timber piles and a timber superstructure. See Map 3 for an aerial view of this culvert.

S-252B is an ungated culvert comprised of two barrels, extending south (open end) to north under Levee L-78, which is an earthen levee with limerock capped driving surface on top. The barrels are CMP, 60 inches diameter by 126’ feet long. The south end has an access pier comprised of steel piles and a metal superstructure. See Map 4 for an aerial view of this culvert.

S-252C is an ungated culvert comprised of one barrel, extending south to north under Levee L-78 and under SR-60. L-78 is an earthen levee with limerock capped driving surface on top and SR-60 is an FDOT 4-lane divided rural section asphalt highway. The barrel is CMP for the southern 120’ and RCP for the northern 168’ (under SR-60), for a total of 288’. The south end has a metal access pier that extends out of the water. The north end has a timber access pier north of the structure. See Map 5 for an aerial view of this culvert.

The engineer's construction estimate for the project is $300,000.00.
