Question:
Item 704.9901, RECONSTRUCT CATCH BASIN OR MANHOLE; the Distribution of Quantities note to perform this item of work at Sta 190+90 RT, but the drawing show 'RCB' - Reconstruct Type "D" Catch Basin to Catch Basin with Gutter Inlet. 'RCB' is RIDOT Item # 705.1300 and this item is not included as an item of work in the Job Specific section 704.9901. Also, to produce 'Balanced Bidding', please provide a vertical footage each contractor should carry in their bid for Item Code 704.0300 Reconstruct Catch Basin/Vertical wall. Without a quantity for each bidder to carry in their bid, each bidder will be guessing at the number of vertical feet to carry in their bid proposal, therefore leading to unbalanced bids. |

Answer:
The proposed drainage work at Sta. 190+90 Rt has been revised. A new pay item has been created to reconstruct drainage structure vertical walls. The changes are included in Addendum No.4. |
