Airport Concrete Wall Repairs & Perimeter Security Fence Installation
The project entails three main objectives:
- To design and effect repairs to the certain sections of the existing concrete wall that recently collapsed due to waves
- To reinforce the concrete wall to prolong its useful life and to withstand wave force
- To design and install a new security fence on the ocean side of the airport
On June 24-25, 2013, Majuro experienced an extreme high tide that coincided with a large southerly swell event. The high tide in combination with wave activity resulted in wave impacts to the seawall/wave barrier along the southern boundary of the Amata Kabua International Airport (AKIA). A number of sections of the concrete wall collapsed as a result. Debris and ocean water covered the runway. The airport was temporarily closed while debris removal and clean up efforts were undertaken by airport staff. The seawater also contaminated the freshwater catchment system of the runway. Fortunately, the airport water pump station is equipped with a discharge system to prevent contaminated water from the runway from reaching the main water reservoirs near the airport. Sand bags were used where the wall sections collapsed as a temporary measure to prevent further debris and ocean water from inundating the runway and causing flight disruptions.
In addition, RMIPA is proceeding with a design-build effort to install a new perimeter security fence along the length of this wall. The security fence design has not yet been finalized, but it will likely entail securing the fence to this wall. The length of the security fence is approximately 8700 ft and will run along the southern boundary of the airport’s runway safety area. The fence project will address security concerns raised by ICAO and TSA inspectors. The lack of a fence system in this area makes the airport susceptible to intrusions or unauthorized access by humans and animals such as dogs.
The fence system to be used is the Guardian 5000-PC Fence system by Betafence USA. It is a welded wire mesh, double powder coated fencing system including framework and barbed wire that is more suitable to the corrosive marine environment experienced at AKIA than a traditional chain link type fence system. It comes with a 25-year performance warranty from the manufacturer. Below is a picture of the Betafence.
