Refer to Specification Section XVIII, Measurement and Payment, for <br />measurement and payment of structural repair types detailed on Sheet 5. <br />2. Engineer may direct Contractor to perform repair work that is greater or less than <br />the estimated quantities identified on the bid form. Contractor shall be paid for <br />actual quantity of repairs. <br />Remove existing concrete using hand chipping methods as required. Do not cut <br />or damage existing reinforcing during concrete removal process. <br />Remove all deteriorated concrete to sound concrete. Prepare concrete substrate <br />to obtain a surface profile of 1/8" in depth with a new fractured aggregate <br />surface. <br />Where reinforcing steel is present and with active corrosion encountered, <br />Engineer will review condition of corroded rebar prior to repair. Replacement is <br />required where loss on rebar cross section is over 10%. After repair where <br />reinforcing remains, clean reinforcing steel to remove all contaminants and rust. <br />If reinforcing replacement is required, cut existing corroded reinforcing bar as <br />required and weld new rebar of same size, as shown. If rebar is not present, <br />place new #3 rebar in field drilled hole in concrete with an approved chemical <br />anchor system according to Detail 5. <br />Surface preparation shall comply with repair mortar manufacturer's instructions. <br />Install concrete per Project Specification Section XXVIII. <br />For bid purposes, total depth of repair is equal to member depth. <br />S, (E) and L1 Definitions correspond to ANSI/AWS D1.4 minimum L1 for bidding <br />purposes is 3". <br />1 <br />2 <br />3 <br />4 <br />5 <br />6 <br />7 <br />8 <br />Do not cut reinforcing unless necessary to remove all deteriorated concrete. <br />Remove all deteriorated concrete to sound concrete. Chip concrete substrate to <br />obtain a surface profile of 1/8" in depth with a new fractured aggregate surface. <br />Where reinforcing steel is present and with active corrosion encountered, <br />Engineer will review condition of corroded rebar prior to repair. Replacement is <br />required where loss on rebar cross section is over 10%. After repair where <br />reinforcing remains, clean reinforcing steel to remove all contaminants and rust. <br />Remove concrete to a depth of 1" minimum behind bar as shown. <br />If reinforcing replacement is required, cut existing corroded reinforcing bar as <br />required and weld new rebar of the same size, as shown. If rebar is not present, <br />place new #3 rebar in field drilled hold in concrete with an approved chemical <br />anchor system according to detail 5. <br />Surface preparation shall comply with repair mortar manufacturer's instruction. <br />Install repair mortar per the manufacturer's requirements. <br />For bid purposes, assume total depth of repair is 4". <br />S, (E) and L1 definitions correspond to ANSI/AWS D1.4 minimum L1 for bidding <br />purposes is 3". <br />1 <br />2 <br />3 <br />4 <br />5 <br />6 <br />7 <br />8 <br />6" minimum spacing. If overall concrete section is less than 9", <br />only two rebar required per layer, centered on section. Layers <br />shall be spaced vertically 12" maximum. <br />Field drilled hole in concrete.
