The machinery drawings call for replacement of the rack and pinions for the bascules. Based review of the existing drawings and the site visit, it appears access beyond what is provided for in the structural drawings may be required to facilitate the replacement of these components. Were any additional access provisions contemplated during the design phase of the project. Will the contractor be allowed to modify the existing bridge and restore to existing condition as needed to provide access to this work?

Based on field evaluations during design, rack and pinion replacement was not anticipated to require modifications to the existing structure with the exception of removal and replacement of the rack and pinion covers as noted in the Mechanical Work Special Provision. However, modifications may be allowed to provide greater flexibility in rigging and installation during the replacement of these items. The Contractor shall include any modifications deemed necessary to facilitate this work in their removal/installation plans and procedures which shall be submitted for review and approval. Any modifications to the existing structure in the performance of this work shall be restored to the existing condition or better.

The notes on Sheet T5 state, ".Typical long slotted holes for 1" bolts are to be used only the bottom flange of the W14x159 cylinder support beam. After alignment is completed, the slotted holes shall be filled with a high strength, non-shrink grout." The drawing indicates the lower cylinder support beam is a W12 x 120. Please clarify the beam size. Separately, Detail A on Sheet T5 does not appear to detail dimensions for slotted holes on the bottom flange of the lower cylinder support beam. Please clarify. The Notes on Sheet T11 state, "Typical long slotted holes for 1" bolts are only to be used in the 1" masonry plate. After alignment is completed, the slotted holes shall be filled with a high Strength Non-Shrink Grout." Please clarify whether this applies to the bottom flange connection of the lower cylinder support beam and provide dimensions of the slotted holes.

The note in question on T5 should read “Typical long slotted holes for 1” bolts are to be used only on the bottom flange of the W12x120 cylinder support beam”. The W12x120 is the correct cylinder support beam to be used, the W14x159 is not. The actual dimensions of the long slotted holes were not dimensioned since it was specified that they shall be typical long slotted holes for a 1” bolt. The long slot dimensions listed in the AASHTO LRFD Bridge Code (1.125” x 2.50”) shall be used in the shop drawing details. In Detail A on T11, the slotted holes are in the 1” masonry plate, not the bottom flange of the cylinder support beam. The note in question on T11 is referring to the long slotted holes in the 1” masonry plate. The actual dimensions of the long slotted holes were not dimensioned since it was specified that they shall be typical long slotted holes for a 1” bolt. The long slot dimensions listed in the AASTHO LRFD Bridge Code (1.125” x 2.50”) shall be used in the shop drawing details. A plan revision will be forthcoming.

Detail B on Sheet T5 indicates there may be a stud projecting out of the inboard anchor plates for the temporary Hydraulic cylinder support beams. There does not seem to be a note defining what this is or the dimensions, please clarify. Detail B on sheet T12 does not show this stud, please clarify whether or not the inboard anchor plates receive a stud for bolting the Hydraulic Cylinder Support Beam Masonry Plates to the inboard anchor plates. Please also clarify whether these holes are to be grouted after bolt-up to the masonry plate.

The Studs that are being referred to in Detail B on Sheet T5 are the 1” Diameter Anchors that are to be cored through the bascule pier front wall. A total of 8 Anchors per support beam are required as shown for the Westbound Bridges. The Dimensions for these anchors are shown in Detail B on the right side of the detail. Dimensions shown are from the CL of the Support Beam. On Detail B on Sheet T12, the outline of the 1” Anchors are not shown due to the various connections being detailed. A total of 12 Anchors per support beam are required as shown for the Eastbound Bridges. The cored holes for the 1” anchors are not to be grouted during initial installation and when the Temporary Operating System is in use. The cored holes through the bascule pier front wall shall be grouted once the Temporary Operating System is removed and relocated to the next Bascule Leaf.
