Assumptions:
The accompanying budget for the services detailed below is based on the services of one full -time-

time the inspector will be required to work on the project.
A full -time inspector is shown for the duration of the project, with the assumption that the final month
of the project will be at approximately half -time due to the project ramping down. Should construction
activities remain at a uniformly high rate, due to the contractor's schedule, poor production rate, or
other reasons beyond Consultant's control, additional inspection services will be provided as
described in Task 6.1.
A part-time Resident Engineer is shown for construction management, and inspection assistance
during complex installations.
Mileage: For the full -time inspector, assume 253 trips at 30 miles for commuting and on -site mileage.
The Resident Engineer and Project Assistant are anticipated to make 30 site visits during the course
of the project at 40 miles round trip. The survey crew is anticipated to make 5 site visits during the
course of the project at 40 miles round trip.
A job site trailer or space at City Hall will be provided and will be equipped with a copy machine, fax
machine (on a separate line), phone and digital answering machine, desk, layout table for drawings,
file cabinet, and other items necessary to facilitate project management, organize project

3. Tukwila Urban Center(TUCI /TOD Transit Plan There is already an ongoing study of the
TUC /TOD areas by Freedman, Tung and Bottomley as well as ECONorthwest. Now Public
Works has selected a contractor to do the Transit Network study that will be a part of the TUC
/TOD study as well as an update to the Transportation Element of the Comp Plan. Staff used a
consultant list to rate who would be best to do this work and selected Perteet, who has what is
possibly the best transportation planner in the region. They were chosen from a list of three
consultants. Perteet will coordinate with the other two consultants. Pam C asked for the tally
sheet used to rate consultants. When asked how Metro's transit plan would fit into this, Cyndy
said this study will be used to fit Metro's plan into this area. Dennis raised the issue of no
residents being included in the stakeholder meetings, and Cyndy said residents could go to any of
the meetings if they were interested. Recommend Consultant Agreement with Perteet for
