  Q:03/29/11
R:04/01/11

Plan Sheet / Specification Reference= Special Provision Section 10-1.11: Maintaining Traffic, Chart No. 5

Question=

Question 1: This Chart is in conflict with the reconstruction work that needs to happen per the Stage Construction Drawings. The reconstruction, in both the Eastbound and Westbound Directions, has 2 stages of work each. Chart No. 5, under the remarks states that this chart is to be used a maximum of (1) time for each direction. Please clarify how stage 2 in both the eastbound and westbound directions is to be completed with one lane closure allowed in each direction.

Question 2: This chart, under the remarks, states that this closure is to be used for a maximum period of 60 continuous days only per direction. Once we clarify question 1 above, Does that work period cover both stages of work in both the eastbound and westbound directions or does it provide for two - 60 day durations per stage of work?

Question 3: This chart, under the remarks, states that each closure direction to be used seperately by the Contractor. Does that mean the Contractor cannot work in the Eastbound and Westbound directions at the same time? If the contractor is precluded from working both Eastbound and Westbound directions at the same time, this statement doesn't get you there. If it is the State's intention to allow the Contractor work in both directions at the same time, what does this remark mean???

  • The intent of the the remarks is as follows:  WB Stage 1 and Stage 2 must be completed within one continuous 60 day closure.   EB Stage 1 and Stage 2 must be completed within one continuous 60 day closure.  The EB and WB closures may be completed simultaneously if the contractor chooses to do so.

  Q:04/04/11
R:04/05/11

Plan Sheet / Specification Reference= Item 28, HMAC, Section 10-1.27,sub section "MATERIALS", sub sub section "Aggregate", second paragraph states: "The aggregate for HMA Type A used as shoulder overlay must complly with 3/8 inch grading."

Question= Previous contracts (11-2M0804)involving an 0.1' cold plane and overlay have allowed, by addendum, the optional use of 1/2" grading aggregate in the shoulder overlay with a high quality finished product. Inasmuch as this is a QC/QA project, as well as an "A + B" project, with great responsibility for performance on the contractor, we request that the supplier be given the option to furnish material with 3/8" or 1/2" grading in order to achieve the best possible finished product at the most competitive cost to the State.

 

  • Please bid per the current contract documents.
