Munilla Construction Management (MCM) has been awarded a $7.9 million bridge rehabilitation contract by the Florida Department of Transportation (FDOT) to improve the SRA1A Peter J. Cobb Memorial Bridge in St. Lucie county.
MCM says it is looking for qualified carpenters, pile drivers, welders, laborers and equipment operators – in the St. Lucie county area to join the MCM team in this rehabilitation project. Those interested can directly contact project manager Yohei Castro at firstname.lastname@example.org.
Slated to commence Oct. 16, the improvements under the contract consist of bridge rehabilitation including scour protection, rubble riprap, gabions, bedding stone, pile repairs, fender system and spalled/delaminated concrete repairs, sidewalk, driveways, fencing, pedestrian/bicycle railing, replacing the existing observation walks, and observation walk lighting along State Road A1A for 0.585 miles over the Intracoastal Waterway.
“Roads and bridges are one of our specialties, we’re confident that we can complete this project on time and on budget while delivering excellent results,” Castro said in a statement.
The project will begin with scour protection; scour is naturally occurring, is the swift flow of water cause by tidal changes. Scour leads to the removal of sediment such as sand and gravel, of the existing channel piers. The new scour protection will be comprised of a combination of a bedding stone layer followed by rubble riprap around the piers at a depth of approximately 25 feet below the water surface. This process will also include the construction of a new fender system containing spalled, delaminated concrete repair to the existing bridge piling system.
New gabion mats will then be installed for protection of non-channel piers, new sidewalks and fencing, giving the project its finished touch. Finally, the existing observation walkway will be replaced with a new piling and deck system installation followed by a concrete pile set and cap installation placed at predetermined spaced intervals, which will contain a double-T beam system on top. This will serve as the walking surface and a rail system to tie the walkway together and allow for safe pedestrian access. The project is expected to be completed by November 2019.
