The reinforced concrete lock chambers are under high scrutiny from the Panama Canal Authority (ACP). The ACP wanted a design life of 100 years, which is a challenge in an area like Panama that is seismically active. According to Wacker Neuson, approximately 300 Wacker IRFU 45 and IRFU 57 internal vibrators with 26-foot hoses were being used in early 2013 to ensure the concrete is free of any entrapped air and allow it to flow into corners and around rebar for an even pour. In addition to the IRFU vibratos, Wacker BS50-4s rammers, PT6LT pumps and CT36-5A trowels are also on the construction site for use on an as-needed basis.
