Documents. When the Anchor Rods are set in sleeves, the adjust- ment provided may be used to satisfy the required Anchor-Rod set- ting tolerances. 7.5.2. Unless otherwise specified in the Contract Documents, Anchor Rods shall be set with their longitudinal axis perpendicular to the theoretical bearing surface. 7.5.3. Embedded items and Connection materials that are part of the work of other trades, but that will receive Structural Steel, shall be locat- ed and set by the Owner’s Designated Representative for Construction in accordance with an approved Embedment Drawing. The variation in location of these items shall be limited to a magnitude that is consistent with the tolerances that are specified in Section 7.13 for the erection of the Structural Steel. 7.5.4. All work that is performed by the Owner’s Designated Representative for Construction shall be completed so as not to delay or interfere with the work of the Fabricator and the Erector.

APPENDIX PAGE 82 The Owner’s Designated Representative for Construction shall conduct a survey of the as-built locations of Anchor Rods, founda- tion bolts and other embedded items, and shall verify that all items covered in Section 7.5 meet the corresponding tolerances. When corrective action is necessary, the Owner’s Designated Representative for Construction shall obtain the guidance and approval of the Owner’s Designated Representative for Design. Commentary: Few Fabricators or Erectors have the capability to provide this sur- vey. Under standard practice, it is the responsibility of others. 7.6. Installation of Bearing Devices All leveling plates, leveling nuts and washers and loose base and bearing plates that can be handled without a derrick or crane are set to line and grade by the Owner’s Designated Representative for Construction. Loose base and bearing plates that require handling with a derrick or crane shall be set by the Erector to lines and grades established by the Owner’s Designated Representative for Construction. The Fabricator shall clearly scribe loose base and bearing plates with lines or other suitable marks to facilitate prop- er alignment. Promptly after the setting of Bearing Devices, the Owner’s Designated Representative for Construction shall check them for line and grade. The variation in elevation relative to the established grade for all Bearing Devices shall be equal to or less than plus or minus 1/8 in. [3 mm]. The final location of Bearing Devices shall be the responsibility of the Owner’s Designated Representative for Construction. Commentary: The 1/8 in. [3 mm] tolerance on elevation of Bearing Devices rela- tive to established grades is provided to permit some variation in setting Bearing Devices, and to account for the accuracy that is attainable with standard surveying instruments. The use of leveling plates larger than 22 in. by 22 in. [550 mm by 550 mm] is discour- aged and grouting is recommended with larger sizes. For the pur-

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
