Bridge No. 0000TUK18 Rehabilitation
A. Proiect Manaaement
Throughout the conduct of these activities, there will be a close
coordination between TranTech Engineering, LLC representative, Kash
Nikzad, PhD, PE and the City of Tukwila's representative, Mr. Robin
Tischmak, PE. Kash Nikzad will manage the activities to ensure submittal
timeliness.
B. Current Load Carrvina Capacity Assessment
In this Task structural analysis is performed to assess the current load
carrying capacity of the Bridge's elements and determine the extent of the
rehabilitation needed.
A 2 -D truss model will be utilized to assess the truss elements. The
elements with deterioration will be subject to cross sectional reduction.
In case all the element capacities are greater than their design demand
then the rehabilitation activities will be composed of only "element
protection measures" for life extension.
In case any of the Bridge's critical elements have load carrying deficiency,
viable strengthening means will be used as part of the next task.
C. Repair/ Strenathenina! Protection PS &E
In this task, PS &E construction documents will be prepared based on the
activities described in Task B.
Our preliminary investigations show that the E. Truss seems to be in
worse condition than the W. Truss. A viable repair needs to address the
large areas of rot and cracking. The top laminations of both bottom and
top chords appear to have lost their load carrying capacity per 2005
inspection report. Top chord has two splice locations while the bottom
chord does not have any splices.
The 2005 inspection report suggests replacing rotted bottom chord
laminations.
8
Floor beams and Stringers are all in State 1, per 2005 Inspection report,
but the stringers are untreated and weathered.
Per client discretion and TranTech's site visit, the deck is in a deteriorated
state and needs to be replaced to provide a viable weather resistant and
non -slip surface.
TranTech will provide Coating and Containment specifications which
includes provisions for initial preparations of the existing timber for coating
purposes. These specifications will be a part of the PS &E Bid Package.
D. Bid Assistance
In this Task TranTech will provide PS &E Bid Package Assistance in the
form of checking all contractor bids for accuracy and providing a reference
check on lowest bidder.
