A berth for a multi-purpose disaster response ship includes: a quay at which the multi-purpose disaster response ship is berthed; a building located along the quay, including at least one quay-facing gate, and sharing at least one common purpose with the multi-purpose disaster response ship; a horizontal movement restrainer that restricts and permits horizontal movement of the multi-purpose disaster response ship relative to the quay; and a vertical movement restrainer that adjusts a vertical location of the multi-purpose disaster response ship to a specified level relative to the quay and that restricts and permits vertical movement of the multi-purpose disaster response ship situated at the specified level.

The bridge construction system and method according to the present invention provides a lightweight, efficient, economical, long-lasting, and easily implemented composite steel structure that can be filled with concrete in place for the construction of pedestrian and smaller road bridges, specifically those found in rural areas. The bridge construction system of the present invention is unique in that it is a steel-frame reinforced composite bridge with decking and rebar caging that provides a permanent, non-removable form for poured-in-place concrete. The composite nature of the bridge allows for installation of the bridge to take place in one day, while the entire process from site preparation such as grading and excavation to cleanup takes a week or less. The quick installation of the bridge is designed to have a minimally invasive impact on the surrounding environment.

An adjustable cable support member includes a first track defining first and second channels extending in a longitudinal direction thereof, and a second track at least partially slideably received within the first and second channels of the first track in the longitudinal direction for enabling adjustment of the overall length of the cable support member. The first track and the second track define a cable receiving space extending continuously in the longitudinal direction over the length of the cable support member.
