1 1. Install temperature data loggers in each concrete pour. One data logger shall <br /> 2 be installed for every 100 yards of concrete placed. Data loggers shall be <br /> 3 installed at locations directed by the Engineer, and shall be placed 1.5 inches <br /> 4 from the face of concrete. <br /> 5 <br /> 6 2. Immediately after concrete placement, temperature data loggers shall be <br /> 111 <br /> 7 installed on the concrete surface at locations directed by the Engineer. One <br /> 8 data logger shall be installed for every 100 yards of concrete placed. <br /> 9 <br /> 10 The data loggers shall be operated continuously during the Cold Weather Protection <br /> 11 Period. Temperatures shall be measured, recorded and stored a minimum of every 30 <br /> 12 minutes. Temperature date shall be submitted to the Engineer as a Type 1 Working <br /> 13 Drawing within three days following the end of the Cold Weather Protection Period. <br /> 14 <br /> 15 If the concrete temperature falls below 40°F during the first seven days of the Cold <br /> 16 Weather Protection Period, no curing time is awarded for that day and the Cold Weather I <br /> 17 Protection Period is extended for one additional day. If the concrete temperature falls <br /> 18 below 35°F during Cold Weather Protection Period, the concrete may be rejected by the <br /> 19 Engineer. <br /> 20 <br /> 21 6-02.3(17)N Removal of Falsework and Forms <br /> 22 The fifth paragraph is deleted. <br /> 23 <br /> 24 6-02.3(25)J Horizontal Alignment <br /> 25 The last two sentences of the third paragraph are revised to read the following single <br /> 26 sentence: <br /> 27 <br /> 28 Any girder that exceeds on offset of inch for each 10 feet of girder length shall be <br /> 29 corrected at the job site to the 1/8 inch maximum offset per 10 feet of girder length before <br /> 30 concrete is placed into the diaphragms. <br /> 31 <br /> 32 6-02.3(26)D2 Test Block Dimensions <br /> 33 The first sentence is revised to read: <br /> 34 <br /> 35 The dimensions of the test block perpendicular to the tendon in each direction shall be <br /> 36 the smaller of twice the minimum edge distance or the minimum spacing specified by <br /> 37 the special anchorage device manufacturer, with the stipulation that the concrete cover <br /> 38 over any confining reinforcing steel or supplementary skin reinforcement shall be <br /> 39 appropriate for the project-specific application and circumstances. <br /> 40 <br /> 41 6-02.3(26)E2 Ducts for External Exposed Installation <br /> 42 In the first paragraph, "ASTM D3350" is revised to read "ASTM D3035". <br /> 43 <br /> 44 In the fourth paragraph, "ASTM D3505" is revised to read "ASTM D3035". <br /> 45 <br /> 46 6-02.3(26)G Tensioning <br /> 47 Item number 1 of the second paragraph is revised to read: <br /> 48 <br /> 49 1. All concrete has reached a compressive strength of at least 4,000 psi or the <br /> 50 strength specified in the Plans. When tensioning takes place prior to 28-day <br /> 51 compressive strength testing on concrete sampled in accordance with Section 6- <br /> I <br /> AMENDMENTS TO THE 2016 STANDARD SPECIFICATIONS BOOK <br /> Revised: C/1/16 <br />
