Item#35, titled Revise Truss Retention Slide Plates,and Item #36,titled Repair Floor Joint Seals are added to the Contract in the amount of$17,415.96. Individual items defined & justified as follows: Item No. 33: Purchase and Install a Magnetrol R82-510A-011 Level Indicating Transmitter(LIT) The condition of the of the existing LIT could not be determined due to the collapsed roof. Once the Design-Builder removed the collapsed roof, it was found that the existing LIT was damaged beyond repair. It was necessary to replace the LIT because it is a requirement to know what the water level is in the Clearwell when it is in operation. Item No. 33 compensates the Design-Builder for providing the level indication transmitter. Increases the Contract Amount by$2,600.00. Item No. 34: Provide Cable Tensioning System for Seismic Cable Bracing System The interior columns that help support the roof are braced to resist seismic forces using stainless steel cables. Theses cables require regular maintenance in the form of checking and adjusting the tension in the cables to the design Engineer's required loading. WFP maintenance staff do not have the equipment needed to perform this task. Item No. 34 compensates the Design Builder for providing the cable tensioning equipment. Increases the Contract Amount by$2,988.94. Item No. 35: Revise Truss Retention Slide Plates The roof trusses are held in place using plates that are anchored to the inside face of the clearwell wall. The roof designer and fabricator refer to theses plates as slide plates. During construction, it was discovered that wall repairs had occurred at the locations where the slide plates were to be installed. These repairs occurred in the early 1990s. Up to half the thickness of the wall had been removed and replaced.After consulting with our Engineers, it was decided to not install the new slide plate anchor bolts into the repaired areas on the walls of the clearwell.To avoid installing anchor bolts into the repaired areas the slide plates were redesigned, enlarged and Page 3 of 4
