COMMISSION AGENDA             Item No.      5b 
Date of Meeting   November 3, 2009 
DATE:    October 22, 2009 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    Ralph Graves, Managing Director, Capital Development Division 
SUBJECT:  Change Order #005 for the Duwamish Trail Link  West Marginal Way SW et al 
Project, Contract MC-0315437 
ACTION REQUESTED:
Requests authorization for the Chief Executive Officer to execute Change Order Number 005 for
the Duwamish Trail Link  West Marginal Way SW et al Project to add the additional time
required (196 days) to complete the project. 
SYNOPSIS:
This project constructed approximately 1030' of new trail for pedestrian and bicyclist use along
West Marginal Way in West Seattle. During the original period of performance, BNSF changed
the requirements for Railroad Protective Liability Insurance. The portions of the work that were
within the BNSF right-of-way could not proceed until the new insurance requirements were met
by the Contractor. Work was suspended until the contractor could comply. We are requesting
CO #005 be issued for an additional 196 days needed to complete the project. This is a no-cost
change order. 

CHANGE ORDER DESCRIPTION AND JUSTIFICATION: 
The following information relates to the pending change order scope and cost: 
Change Order No. 005 
Scope of work: The original contract completion date is 10/31/08. CO #005 will add an
additional 196 calendar days to the contract duration due to the suspension of work.
Justification: Although the Contract included provisions requiring the contractor to
procure Railroad Protective Liability insurance for the portions of the work that impinged
on the BNSF right-of-way, this insurance requirement was increased by the Railroad part
way through the contract work. The delay created by this additional insurance
requirement was exacerbated by the requirement that all the contractor's employees
undergo railroad safety training prolonging the duration of the suspension. The direct
costs with the additional insurance and additional required training were covered by CO
#004 issued previously for a total cost of $5000. CO #005 accounts for the time
