i <br /> component for any improper welding . Perform all required verification and testing at no expense <br /> to the Department and to the satisfaction of the Engineer . <br /> Do not use stay- in-place metal forms until the forming system has been <br /> approved by the Engineer. The Contractor is responsible for the performance of the stay- in-place <br /> forms . <br /> Structures designed, detailed, and dimensioned for the use of removable <br /> forms : Where stay- in-place metal forms are permitted, the Contractor is responsible and shall <br /> obtain the approval of the Engineer for any changes in design, etc . to accommodate the use of <br /> stay- in-place forms . The Engineer will compute pay quantities of the various components of the <br /> structure which are paid on a cubic yard basis from the design dimensions shown on the plans 1 <br /> with no allowance for changes in deflection or dimensions necessary to accommodate the stay- <br /> in-place forms or concrete to fill the form flutes . The Engineer will limit pay quantities of other <br /> Contract items that the Contractor increases to accommodate the use of stay-in-place forms to the <br /> quantityrequired for the original plan design . <br /> Submit all changes in design details of bridge structural members that <br /> support stay-in-place forms , showing all revisions necessary to enable the supporting <br /> components to withstand any additional weight of the forms and the weight of any extra concrete <br /> that may be required to fill the forms . Include with the design calculations a comparative analysis <br /> of the stresses in the supporting components as detailed on the Contract plans and as modified to <br /> support the forms . Use the identical method of analysis in each case , and do not allow the <br /> stresses in the modified components to exceed those of the component as detailed in the Contract <br /> plans . Include with the design the adjusted cambers for any changes in deflection over those <br /> shown on the original plans . Modify the beams to provide additional strength to compensate for <br /> the added dead loads imposed by the use of stay-in-place forms . Obtain the additional strength <br /> by adding strands to the pre- stressed beams or by adding steel material to increase the section <br /> modulus of steel girders . Substantiate the added strength by the comparative calculations . Do not <br /> use stay-in-place forms until the forming system and all necessary design revisions of supporting <br /> members have been approved by the Engineer . <br /> Structures designed, detailed, and dimensioned for the use of stay-in-place <br /> metal forms : <br /> Prior to using stay-in-place metal forms , submit detailed plans for <br /> approval of the forming system (including method of support and attachment) together with <br /> design calculations . Include an analysis of the actual unit weight of the proposed forming system <br /> over the projected plan area of the metal forms . If the weight thus calculated exceeds the weight <br /> allowance for stay-in-place metal forms and concrete required to fill the forms shown on the <br /> plans , then modify the supporting components to support the excess weight as specified by the <br /> Contractor ' s Specialty Engineer. <br /> For all structures utilizing structural steel supporting components , paint <br /> the vertical sides of the top flange prior to installation of the stay-in-place metal forms in <br /> accordance with Section 560 . <br /> For non-polymer sheeting form surfaces , use zinc paint coating in <br /> accordance with Section 562 to all accessories cut from galvanized sheets , which are not <br /> embedded in concrete . <br /> - 135 - <br /> FPID (S ) : 423186 - 1 - 58 - 01 <br />
