If information contained herein is thought to be inaccurate or incorrect, please contact writer at once for resolution.

The following pertains to items discussed at the pre-bid meeting, related to the Repair Steam Tunnel and Water Infiltration project.

• Bids are due Wednesday, March 25.

• An addendum is forthcoming to aid bidders and provide clarifications.

• Questions from bidders are to be received by March 17.

• Bidders can expect to hear back about their bid-status sometime in early May.

• Tunnel is split into sections, with the intent that sections may be removed for budgetary reasons if necessary.

• All noted degradations on the drawings are paired with like photos, for the bidders’ reference.

• Majority of work involves repairing concrete delaminations/spalls present throughout the tunnel and repairing/replacing rusting stanchions.

• There were notable obstructions present at some degradations which need to be accounted for in the bids.

Cable trays may need to be moved if they are in the way of a repair item.

Conduit may need to be moved if it is in the way of a repair item.

Degradation areas may extend into an area behind a major steam pipe, making them partially inaccessible.

• Repair of delaminations and spalls has a required engineering inspection, as stated on the drawings. The intent of the inspections is to get an engineer onsite to inspect the repair work at three different times.

Limits of repair marked Repair areas prepped Repair completed

• Due to the size and likely duration of the project, there will likely be some logistical issues with the timing of these different inspections. Fishbeck plans on coordinating these inspections further with the contractor as the time nears.

• DTMB staff mentioned a planned shutdown (typically in early October) which lasts for about a weekend. This could be used to aid in the project.

• Bidders voiced that the current handling of the work related to dealing with obstructions in the spall/delamination unit price could be better. It was discussed and a general consensus was reached that breaking out the obstructions as separate items was a preferrable option.

• Fishbeck is following up to provide the following information in Addendum 1 Extents of shorter tunnel section, along with a description/cross-section of the tunnel section.

Rework the unit price items. Concrete spall/delamination work is to be a separate item from their related obstructions.

1. INFORMATION ON THIS SHEET SUPPLEMENTS THE PROJECT SPECIFICATIONS. REFER

TO THE PROJECT SPECIFICATIONS FOR ADDITIONAL REQUIREMENTS.

2. THESE DOCUMENTS HAVE BEEN PREPARED BASED ON VISUAL INSPECTIONS AND

SOUNDING OF EXPOSED AREAS OF THE EXISTING STRUCTURE. REPAIR QUANTITIES

HAVE BEEN ESTIMATED AND ARE REFLECTED IN THE BID PRICE SHEET. THE

CONTRACTOR IS RESPONSIBLE FOR INSPECTING REPAIR AREAS. DELAMINATIONS

SHOULD BE VERIFIED USING A SOUNDING TOOL. LIMITS OF ALL DELAMINATIONS AND

SPALLS SHALL BE MARKED FOR ENGINEER'S INSPECTIONS.

3. OBTAIN ENGINEER'S REVIEW PRIOR TO MAKING ALTERATIONS TO A STRUCTURAL ITEM

OR MEMBER NOT INDICATED ON THE DRAWINGS.

CONCRETE REPAIR NOTES

1. FOR UNIT PRICE BID PURPOSES, ASSUME ALL SPALLS AND DELAMINATIONS HAVE A

DEPTH OF 3".

2. QUANTITIY OF REPAIRS IS ESTIMATED BASED ON OBSERVATIONS MADE DURING FIELD

INSPECTIONS. FINAL QUANTITY TO BE DETERMINED ONCE AREAS ARE PREPPED FOR

REPAIR AND VERIFIED BY ENGINEER.

3. UNIT PRICING FOR CONCRETE SPALL AND DELAMINATION REPAIRS IS TO INCLUDE ANY

REQUIRED WORK ASSOCIATED WITH TEMPORARILY MOVING AND RE-ATTACHING

UTILITIES THAT ARE OBSTRUCTING WORK. REFER TO RESTORATION SCHEDULE AND

SHEET S002 FOR A DESCRIPTION OF OBSTRUCTIONS.

1. STRUCTURAL STEEL STANCHIONS MARKED FOR A "CLEAN AND COAT" REPAIR HAVE

BEEN PHYSICALLY MARKED "CC" IN THE FIELD BY FISHBECK. THESE STANCHIONS AND

THEIR BASEPLATES AND FASTENERS ARE TO BE TREATED WITH A STEEL COATING

SYSTEM. STEPS FOR SURACE PREPARATION AND APPLICATION OF THE COATING OF

THE SYSTEM SHALL BE DONE IN ACCORDANCE WITH THE MANUFACTURER'S

RECOMMENDATIONS AND SPECIFICATIONS. APPLY COATING AROUND THE ENTIRE

STANCHION VERTICAL MEMBER AND TERMINATE AT A LOCATION SUCH THAT THE

EXTENTS OF THE DEGRADATION ARE COATED. COAT A MINIMUM OF 1'-0" ABOVE TOP OF

FLOOR.

2. STRUCTURAL STEEL STANCHIONS MARKED FOR A "BASE REPLACEMENT" REPAIR HAVE

BEEN PHYSICALLY MARKED "BR" BY FISHBECK. REFER TO TYPICAL STRUCTURAL STEEL
