Executive Summary
Background and Methodology
Jilk Heavy Construction, Inc. (JHC) conducted a routine inspection of the Redondo Sport Fishing Pier in August 2021 and a follow-up inspection in September 2022, for the City of Redondo Beach, CA.
The scope of this work included visual inspection of both the above water and underwater pier structure, approximately 243’ of pier.
The inspection at the Sport Fishing Pier included an above and below water inspection that focused on visually inspecting the piles, braces, and caps as well as on the soundness of the overall structure to ensure the structure is sound enough to not pose a public hazard while not occupied.
During the inspection in August 2021, multiple structural members showed signs advanced deterioration or wore already compromised placing more stress on the surrounding structure. The follow-up inspection conducted September 2022 found that there was an accelerated rate of further deterioration of many supporting structural members. The area of most concern is bents 3 through bent 6 where, 7 of the 12 piles are 100% deteriorated. Also, bents 9 and 10 are severely structurally compromised. Along with the severe pile deterioration, the majority of bracing from bent 3 to bent 10 is severely damaged or missing. The pier structure at bents 3 through 6 are at a point where they could collapse with very little outside forces. It is recommended that this structure be demolished immediately to avoid hazard to the public and possible environmental contaminations.
The following report is a more detailed summary of the condition of the pier facilities mentioned above including a site plan of the observed damage and pictures of some of the more severe damage. ····· ABCD ABCD 1 2 3 4 5 1 2 3 4 5
