Amendment_27_Q&A_16_May_2017.docx

1. The new Bid Schedule has added CLIN 0004, Removal and replacement cost associated with subgrade that fails the proof roll test. There is no quantity associated with this new item of work. We have no way of knowing at this time what quantity to expect. Please provide a quantity to include in the bid so that all bidders are pricing the same quantity and scope of work. If no quantity is provided by the Government for bidding purposes, are we to just provide a price per cubic yard for this item and then exclude this item from the bid total? The proof roll test is required for the entire Brownie Pad, which there is a quantity (see revised Bid Schedule).

2. Since we do not have a detailed set of plans to use to check and verify quantities of work on this project, will the government consider making this a unit priced contract in lieu of a lump sum contract? Contract will be a lump sum contract

3. The response to question 9 in Amendment 2 states: “All unused soil must be tested and taken to an approved disposal facility.

After testing the soils for contaminates, the results meet all EPA and VDEQ clean fill standards, the soils can be disposed at a permitted facility.
