The repairs for each truss have been designed to the original design criteria set forth in the referenced truss design drawings. Each truss repair drawing relies solely upon information provided by others.We have made no investigation of the specific items requiring repair,job site conditions or factors that may have necessitated the repairs or may affect the truss.Any variance from the information provided will render the affected truss repair drawing inapplicable. Listed below are the truss repair drawing(s)included in this package and covered by this seal: job:21-0371 -1149866 T04 Any location identification is for file reference only. No determination of the appropriateness of original design criteria for any specific project has been made in preparing the truss repair drawings. Please refer to original individual truss design drawings for specific design criteria. 08/04/20 REG/, 39632 AL•• Arturo A.Hernandez(CO, PE-39632) My license renewal date for the state of CO is 10/31/2021.
