Article 1 — Description
Adjust and reset steel shoes as shown on the plans .
Article 2 — Construction
Remove the existing welds between the shoes and the girder flanges by arc -air gouging. Loosen or remove anchor bolt nuts as required to allow free vertical movement before raising. Jack the girders up to free the shoes and allow the pin between the top and bottom bolsters to rotate freely. Drive out the pin if it does not rotate freely, then clean and lubricate it before reinstalling. Reset the shoes relatively plumb for a temperature of 70°F. Lower the girders and reweld the shoes in this position. Use the same weld size as the original weld unless directed otherwise. Weld and grind smooth any excess gouges caused by weld removal. Grind any original weld metal not removed by arc -air gouging. Grind all exposed corners to a 1/16- in. radius. Use jacks with a c apacity adequate to raise the girders free of the shoes without exceeding a bearing pressure on the concrete cap of 1,500 psi. Use jacks with a capacity of at least 1.5 times the shoe design load or as shown on the plans. Repair any concrete spalls caused by the Contractor’s operations in accordance with Item 429, “Concrete Structure Repair.” Replace any shoes or parts of shoes as shown on the plans.
