rehabilitation of a 330 linear foot of seawall at Muss Park. An evaluation of the seawall discovered that
the wall had cracks and structural deficiencies, and even some portions of the wall had fallen off. Atkins
North America, lnc. designed a wall with a traditional steel sheet pile system, incorporating tie-back
anchors, The design was completed in May 2014.
ln June 20'14, Public Works staff members attended an engineering conference where they were
introduced to Truline, a manufacturing company specializing in industrial valves. One oi highlights of the
presentation was a hybrid sheet piling system. Staff took special interest in this product for its potential
usage for seawall construction, including the following benefits:
. lt is a steel-reinforced, concrete filled, polymer U-channel that provides the strength of a traditional
wall;. The installation method is efficient and boasts a 50 year service life (a kaditional seawall service
life lasts approximately 30-a0 years); andr The cost estimate to construct a traditional sheet pile system at Muss Park is approximately
$776,000, The cost estimate to construct a Truline hybrid sheet pile system is $390;000,
representing a \Qo/o cost saving for the City.
The proposed hybrid sheet pile system is manufactured by Truline and installed by MAI Engineering
Services. Their experience with using this product in the past few years in the State of Florida has prorren
to be successful. Public Works staff would like to try out a pilot program for the Muss Park seawall, and
execute a contract agreement with MAI Engineering Services to construct the hybrid seawall.
