This type of cold-formed steel sheet pile cofferdam, MMZ28-1, is susceptible to damage from large seepage (MMZ28-2) and flooding (MMZ28-3). Therefore, this type of cofferdam is suitable for situations with low water heads (approximately 6 meters). Cofferdam materials include wood, concrete, and steel. The MMZ28-1 wood-steel sheet pile cofferdam is suitable for situations with low water heads (e.g., up to 3 meters). The MMZ28-2 steel cofferdam is suitable for situations with water heads up to 6 meters. The MMZ28-3 concrete cofferdam is suitable for situations with limited headroom. Bored and cast-in-place steel sheet piles should be used to minimize noise and vibration.
Cagayan sheet pile recommendations MMZ28-4 focus on projects that may impact underwater cultural heritage (MMZ28-5). MMZ28-6. Examples throughout this document are drawn from the case studies in the appendix. However, it is important to note that port construction projects often straddle land and sea boundaries, and terrestrial and intertidal archaeological considerations may also need to be considered when planning port construction projects. While many of the recommendations presented in MMZ 28-5 may also be relevant to these environments, consideration of specific archaeological issues above the low water mark is beyond the scope of this document.
To assist with construction, MMZ 28-6 will construct a dedicated facility adjacent to the aggregate storage area. This facility will be sized to accommodate up to 60 construction workers and will include temporary offices, a canteen, and restrooms. These facilities are expected to utilize a portakabin-style structure.
