An apparatus and method for reinforcement of partially submerged structural elements such as piles, posts, pillars, and pipes are disclosed. The apparatus includes an upper unit which may be fixed to the structural element above the waterline and a lower unit which is suspended from the upper unit via cables or other support members. The apparatus enables a reinforcing sleeve structure to be constructed in multiple segmented layers from above the waterline which the sleeve structure is lowered beneath the waterline. The lower unit guides the lower end of the sleeve structure down around the submerged portion of the structural element and supports the weight of the sleeve structure until it is fixed in place and filled with concrete or another reinforcing core filler material.

Bridge systems and methods for constructing bridges having overhang surfaces employing generally rectangular, precast, prestressed concrete panels. One method includes delivering a plurality of generally rectangular, precast, prestressed concrete panels to an installation site, and delivering one or more support beams to the installation site, each support beam having a support and a base. The concrete panels are positioned on the supports of the one or more support beams with an overhang panel section and a traffic panel section. The concrete panels are then connected to the support beams by positioning steel reinforcement in block outs or voids, pouring unsolidified concrete into the voids, and curing the unsolidified concrete to form an overhang traffic surface. Bridges constructed employing the precast, prestressed concrete panels and methods. Other bridge systems employ prestressed concrete L-walls and double-T members, where weight-bearing L-walls have pockets for webs of the double-T members.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

A jacking force transfer method to compress prefabricated deck units and to tension bridge girders. Prefabricated deck units are placed on top of bridge girders. Relative motion between girders and deck units is permitted along the direction of bridge girders while deck units are first installed. Subsequently, an end deck unit is made composite with the girders while jacking brackets are installed on top of the deck unit on the other end of the bridge. Hydraulic jacks react with jacking brackets to introduce a longitudinal compression in prefabricated deck units and, at the same time, a tension in the girders.
