AKIA Wall Repairs and Security Fence Installation Update

Pre-Design Services for the referenced project will soon commence.  This follows the signing of a professional consulting services contract between the RMIPA and AECOM Technical Services Inc. (AECOM). AECOM, which has an office in Honolulu HI, is a global leader and provider of engineering and management services and “has been providing consulting engineering services to the Hawaii and Western Pacific Region for over 50 years.”

A team of AECOM engineers are expected to travel to Majuro the week of July 21, 2014 to commence site investigation and survey works to determine the nature and condition of the existing concrete wall. “The wall at the airport is more than 20 years old and is in poor condition,” says RMIPA Director Jack Chong-Gum. “The existing wall is a crucial and valuable asset of the airport infrastructure as it not only prevents inundation of the runway from ocean water but also protects contamination of the water catchment.” The runway water catchment supplies approximately 223 million gallons (source: MWSC, 2011) of rainwater annually to the island’s main water reservoirs near the airport. “So you can appreciate why the RMIPA is taking a proactive approach by developing necessary design solutions to improve and reinforce the concrete wall in order to prolong its useful life and also to ensure it is able to withstand future wave forces,” Chong-Gum added.

Installation of the new security perimeter fence at the ocean side of the runway should commence shortly after completion of the wall repairs. The fence is to address security concerns raised by civil aviation authorities, as well as to prevent wildlife from accessing the airport operations area. Wildlife such as dogs, cats and birds are a safety risk to aircraft operations.

The RMIPA will provide updates on this project as work progresses.

Construction of RSA Barrier Wall

Earlier this year on three separate occasions, high spring tides and large swells caused erosion along the Lagoon side shoulder of the Runway Safety Area (RSA) project site.  The severe weather identified a weak point in the design which would reduce the lifespan of the revetment and soon to be built new road if not addressed.

The RMIPA successfully got approval to construct a cement treated base course (CTB) and a concrete barrier wall. These improvements, designed by Beca International Consultants, will greatly enhance the protection to the road shoulder and pavement. Below are some photos of the CTB and wall currently under construction.

RMIPA Accepting Proposals for Revetment Project

The RMI Ports Authority is now soliciting bids for the construction of a rock revetment in Majuro lagoon along the northeastern coastline near Amata Kabua International Airport (AKIA).

This section of seabed north of the existing revetment has been dredged to accommodate the Runway Safety Area (RSA) upgrade and the new revetment will protect the existing shoreline from erosion in that area.

RMIPA has worked closely with RMI Environmental Protection Authority (EPA) to ensure that the construction of the RSA is in compliance with all environmental mitigation requirements and the Dredge Site Revetment Project is a big part of those efforts.  RMIPA Director Jack Chong-Gum believes that the project will be essential to public safety and for reducing possible negative environmental impacts.

“We have all experienced the effects of flooding here recently and the new revetment that RMIPA is constructing will go a long way toward protecting us against those types of events,” Chong-Gum said.  “Not only can we prevent erosion, but we will also safeguarding our assets like the road and water supply reservoirs near the airport.”
