|Publication Date:||1 January 2008|
This work shall consist of the construction and removal of temporary facilities that are generally designed by the Contractor and employed by the Contractor in the execution of the work, and whose failure to perform properly could adversely affect the character of the contract work or endanger the safety of adjacent facilities, property, or the public. Such facilities include but are not limited to falsework, forms and form travelers, cofferdams, shoring, water control systems, and temporary bridges. Appropriate reductions in allowable stresses and decreases in resistance factors or imposed loads shall be used for design when other than new or undamaged materials are to be used. To the extent possible, calculations shall include adjustments to section properties to account for damage or section loss.
Unless otherwise permitted, the design of the temporary works shall be based on AASHTO LRFD Bridge Design Specifications load factors specified in Articles 3.4.1 and 3.4.2, and all applicable load combinations shall be investigated.
