We have received the following question from our electrician regarding electric duct relocation at Sta. 1+31, signal relocation Sta.

5+27, Sta. 8+60 Sta. 10-+41: In Reference to drawings MS-101 notes 11 & 13 and MS-102 notes 14 & 15 please clarify the existing electrical conditions. It appears there are both Medium Voltage and

Fiber Optic cable. If it is expected to relocate these, We will need a specification to know exactly what the cables are in order to splice/extend, and also need to know where they originate.

The Steam and Condensate Pipeline Profiles are shown on Drawings MS-201 & MS-202. Where conflicts exist between the proposed new pipelines and existing utilities, these existing items are indicated to be relocated. All other known utilities, based on best available information, are indicated on the profiles as well. This is for informational purposes. All excavation should be done in a manner that will not damage existing utilities. Location of all utilities and hand excavation as required to prevent damage is the responsibility of the contractor. The cost for full repairs of known utilities damaged by the contractor shall be borne by the contractor and shall not constitute an acceptable reason for claim of delay.

Refer to Specification 26 05 41 for Electrical Duct

Bank and Buried Conduit requirements. For Bidding

Purposes, Where Fiber Optic Cable is indicated to be relocated, assume Singlemode 9/125, 6-strand, fiber optic cable in conduit, including any required splices, pull boxes, and appurtenances to maintain service.

We are also asking you to revise the Bid Tabulation Page after

Amend. #02 deleted BID ITEM III.

Bid Addendum No. 2 already removed this from the project. For clarity, notes have been added to the Bid

Tab indicating that Bid Item III (Deduct Alternate No

2) is Removed from the Project.

Lastly, please clarify the STATEMENT OF BID ITEMS:

Normally contractors are to provide the overall total ..BID ITEM I.

If adds /deducts were required they would be individual deducts from the total bid. In this instance the STATEMENT OF BID

ITEMS appears to accumulate the deducts. See below example table.

Table Received from Contractor Below:

END OF LOG

This understanding of the Bid Documents is incorrect.

The VA is not required to take Bid Deduct Alternates in Order and are not Cumulative. Provide a Cost for the Base Bid as if No Deducts are Accepted and then provide a Cost for each Bid Deduct Alternate independently of each other. The Bid Tabulation Page specifically denotes all Bid Deducts as Separate items for this reason. After Bid, it is the Government's prerogative to select any combination of Bid Deduct

Alternates.
