Engineer Carlos Luis Hernández Bravo stated that the South Viaduct project requires specific cement types rather than generic concrete due to durability concerns. [^1]

City Administrator Mell Smigielski stated that obtaining the U.S. Army Corps of Engineers permit was the hardest part of the project due to strict state and federal environmental rules protecting nesting sea turtles and shorebirds. [^2]

Construction of the new pier will begin after the two-week funding phase concludes, with work starting at the end of 37th Street and taking approximately one year to complete. [^3]

The city has secured a $10 million FEMA funding package, which is in its final two-week congressional notification phase before funds are released to the state and transferred to the city. [^4]

The new pier will be redesigned to be 230 feet further into the Gulf, allowing anglers to fish in 20 feet of water instead of 6 feet, while maintaining its original 840-foot length. [^5]

For the Coca Codo Sinclair hydroelectric plant, the engineer utilized High Early Strength (HE) cement containing volcanic pozzolana to achieve early resistance. [^6]

Hernández Bravo noted that in 2001, he designed concrete mixes for the Manta Air Base expansion under USACE supervision, using Type I Portland cement with 6% air entrainment for saline environments. [^7]

Hernández Bravo recommended that the South Viaduct project use mobile concrete plants and potentially add pozzolana on-site to optimize designs and costs. [^8]
