STREET PROJECT, PW-R-152
DRAFT SCOPE OF SERVICES
PROJECT OBJECTIVE
The NE 8th Street project, PW-R-152 will improve area traffic circulation with the addition of a
westbound right-turn lane between 108th Avenue NE and 10th Avenue NE. The Bellevue’s
Downtown Implementation Plan Update determined that the NE 8th Street project was a
cornerstone project necessary for the efficient operation of subsequent circulation projects in the
downtown core. This project removes a major checkpoint on NE 8th Street heading west from I405 through Downtown. It benefits customers, employees, and transit by reducing delay
entering the City. A Major element of the Consultant’s work will be the identification and
evaluation of engineering discipline reports to satisfy federal grant and NEPA environmental
permitting requirements with the creation of a complete set of roadway plans, specifications and
estimate (PSE).
PROJECT DESCRIPTION
The NE 8th Street project includes the addition of a westbound lane on NE 8th Street (between
108th Ave. to 106th Ave.) becoming a right turn lane at 106th Avenue NE with street frontage
improvements on the north side of NE 8th Street. Street frontage improvements will include: 6foot wide concrete sidewalks, street lights, storm drainage facilities, curb and gutter, and
driveway openings. The Design will include:


meetings, and planning work items for the following month. This work element is intended to
help monitor costs and budgets and to propose corrective actions. All communication between
the City of Bellevue and the Consultant shall be through the City of Belleuve Project Manager.
SUBCONSULTANT COORDINATION
Direction of Subconsultants and review of their work over the course of the Project shall be
provided by the Consultant. This work element includes reviewing monthly progress, invoices,
attending meetings, and scheduling and coordinating work items for the following month.
Monthly monitoring of the Subconsultant’s design budget will occur over the course of the
Project. Current status, as well as projections, will be developed. This work element is intended
to help monitor costs and budgets and to propose corrective actions. These actions could include
formal requests for scope modifications and respective budget adjustments.
MODIFIED PROJECT WORK PLAN
Consultant shall develop a work breakdown structure (WBS) to identify tasks necessary to
complete the PS &E and determine assignments, schedule and budget for each task. A schedule
shall be developed from the WBS by the Consultant to track progress of the PS&E deliverables.
The schedule shall establish dates for submittal of PS&E, as well as dates when City action is
required. The schedule shall be developed based on a project advertisement no later than May
2007. This information shall conform to the City’s project template and will be incorporated into
the project’s MS Project critical path schedule. The schedule will be updated monthly.
The schedule timing and sequencing in this contract is subject to adjustment by the City, as
affected by cash flow, mitigation, or other factors that may influence the scheduling of work.
Any adjustment in the schedule shall be coordinated between the City and the Consultant. No
modifications shall be made to the schedule without prior written approval from the City. The

Consultant will develop strategies/recommendations for keeping the project on schedule and
within budget, if changes are required.
QUALITY CONTROL/QUALITY ASSURANCE REVIEW
This task is for QC/QA review of the Consultant’s deliverables by a designated QC/QA staff
member. The review shall cover documents, reports, plans, specifications, cost estimates and
pertinent information on an ongoing basis. The QC/QA program entails the periodic review of
design assumptions, concepts and presentation of product format and assures that the overall
Project objectives are being fulfilled. The consultant will need to use the City’s quality control
checklist and provide a summarized list of all review comments.
The City will provide additional quality review. This will be coordinated with the Consultant
Project Manager and pertinent staff members. Support groups within the City will review and
provide direction of pertinent work items and will coordinate with the Consultant Project
Manager and pertinent staff members.
BASE MAPPING
COMPILE BASEMAPPING
The City of Bellevue will supply an electronic copy of the alignment survey depicting existing
centerline and right-of-way lines for NE 8th Street and an electronic copy of an aerial map of the
project limits.
The base map shall include:

Topographic survey within existing right-of-way. Survey shall include all significant
features including roadway, edge of pavement, utility covers, signs, trees over 6
inches in diameter, driveways, fences, walkways, walls and other significant
topographic features;

Survey within right-of-way at a maximum of 25 foot intervals along existing
centerline;
The topographic survey shall be completed so that 0.5 foot contours can be generated from the
raw data points.
Base maps shall be tied to existing monument control and defined on the plans. The plan
boundaries shall extend from the east side of the intersection of NE 8th Street and 108th Avenue
to the west side of the intersection NE 8th Street and 106th Avenue NE. All elevations shall refer
to the North American vertical datum. (NAVD 1988). Control and reference shall be NAD 8391.Horizontal control shall be referenced to City of Bellevue local project datum as depicted on
the alignment survey. The consultant will have to verify their base mapping and check the
accuracy of their digital terrain model (DTM).

of work and should be accounted for. The Consultant shall notify the City and franchise utility
companies and request utility as-builts. The Consultant shall field verify all as-built information
of existing underground utilities. A topographic survey of surface utilities will be conducted and
all catch basins and manholes will be opened to verify pipes or invert elevations.
ADDITIONAL SURVEY
The Consultant shall perform additional topographic survey as directed by the City, and must be
approved by the City prior to execution. Additional survey needs may include:





Retaining wall locations;

Locate test pits/borings for geotechnical investigators.
ENVIRONMENTAL DOCUMENTATION
ENVIRONMENTAL REVIEW
Preliminary NEPA environmental documentation for the project has been completed by the City
and is represented by the FEIS for the Transportation Facilities Plan. Supplemental site
investigations, reports and mitigation plans may be necessary for the design and permitting of
this new work within the project limits. In order to determine what, if any, additional studies are
necessary the Consultant shall:
