Submit design calculations for the forming system, which have been signed and sealed by the Specialty Engineer. Detail stay- in-place metal forms such that they in no way infringe upon the concrete outline of the slab shown on the plans . Use stay- in-place metal forms that provide and maintainIT - the dimensions and configuration of the original slab in regards to thickness and slope , Do not weld stay-in-place metal form supports and connections to the structural steel components . Do not connect polymer coated angles or other hardware that support polymer coated metal forms to the beam attachment straps or clips by welding. Electrical grounding to reinforcing steel is prohibited . Protect structural steel components from damage by using a shield to guard against weld splatter, weld overrun, arc strikes , or other damaging effects of the welding process . Upon completion of welding, rest the metal form support flush on the supporting steel component . Should any weld spatter, weld overrun, arc strike , or other effects of the welding process be evident or occur to the structural steel component, immediately stop in -place welding of the metal form supports for the remainder of the work . In this event, weld all metal form supports off of the structure and erect the forms after prefabrication, or use an alternate approved method of attaching the form supports .
