Given Information CSXT Owner (Major Maintenance) Low Volume, Minor Collector (Rural) Original Design Load H10 (10T = 20,000 lbs.

GVW) NYSDOT Inspection (Critical Event) Rated for 20T prior to inspection Load Posted to 4T in 2012 Structurally Deficient, Sufficiency Rating 43.3 Numerous Deterioration “Red Flags” Emergency Contract:

Bergmann Associates, Albany Office

First thoughts on the Project

Repair

Rehabilitate

Replace

• Original 20 Ton rating not possible in only repairing minor item(s).

• Repair current inspection “red flags” and also ones predicted for next inspection cycle (“yellow flags”).

• Restore Previous Load Posting (20 Ton) or Greater

• Most expensive option and one that the Owner had not budgeted.

Rehabilitation Scope Remove Asphalt Overlay, Timber Curb, and

Timber Deck Complete Steel Repairs to Trusses,

Floorbeams, and Bottom Lateral Bracing Remove and Replace Timber Stringers (as

needed) Install New Timber Deck & Curb, Pave Asphalt

Wear Crs. Re-open to Traffic Restrictions: No Construction Loads except Personnel; No

Temporary Reduction in Vertical Clearance; Temporary Shoring of Diagonals and Floorbeams required during Gusset Plate Repair/Replacement ; One Gusset Plate Repair at a Time

Moving Toward Bid A couple problems came to light about this

plan …

… IT WASN’T A LONG TERM SOLUTION SO NO ONE WAS REALLY HAPPY WITH

THE SITUATION.

… IT WAS COSTING MORE THAN EXPECTED.

addition) Bid Results

Two Bids: $300k; $677k Only the Low Bidder Submitted an Alternate Bid:

$550k

One last ‘i’ and one last ‘t’ What was it going to cost to

recondition the existing abutments? If a ‘GO’, would the Town of East

Chatham be willing to own the bridge?

So Bergmann prepared schematic TS&L type plans (30%).

They were.
