EXHIBIT A
SCOPE OF WORK AND SPECIAL TERMS AND CONDITIONS
CONVEYANCE ENGINEERING SERVICES
FOR THE CEDAR MILL TRUNK JENKINS TO BEAVERTON INTERCEPTOR
PROJECT NO. 6882
I. PROJECT DESCRIPTION
The District’s calibrated sanitary sewer model indicates the Cedar Mill Sanitary Trunk (which is
located within the Cedar Mill Creek corridor) will be capacity-deficient by 2025. However,
flowmeter data has shown significant surcharging during recent storm events suggesting the
improvements may be needed sooner. Additional modeling conducted by the District
demonstrated upgrading approximately 4,900 feet of the trunk to 48-inches (through the Cedar
Mill Creek corridor south of Jenkins) would eliminate the need to upgrade the upstream portion
of the trunk sewer through the Nike campus in the near future. The proposed enhancement
actions associated with Washington County’s Jenkins Road improvement make this the ideal
time to collaboratively upgrade the Cedar Mill Sanitary Trunk as part of the road improvements
project.
An alternatives analysis has identified a preferred alignment to construct a new 48-inch trunk
line. Concurrently, the Project team has identified a suite of enhancement actions within the
Cedar Mill Creek corridor to improve stream and floodplain resilience and improve storage and
attenuation to mitigate the incremental increase in flows from the Washington County Jenkins
Road improvement project. This scope of wok covers project management, design services,
geotechnical engineering, permitting support, bidding and construction support. The scope also
includes detailed survey work, erosion control plans, and coordination for both the sanitary
sewer and enhancement Projects.
II. SCOPE OF WORK
Task 1 – Project Management

2. Coordinate and attend a Project kick-off meeting with District Project management staff to
discuss Project elements, background, scope, schedule, design criteria, operation and
maintenance concerns, and District preferences. District will provide Consultant copies of
as-built or record drawings of the system, as requested by Consultant.
3. Develop a schedule identifying critical tasks to meet the Project completion date. The
schedule shall be updated as necessary and reflect the resources required to meet Project
deadlines.

Task 2 – Topographic Base Map
Consultant shall:
1. Field Survey: Perform a comprehensive field survey of existing conditions within the
Project area shown on the map attached hereto as Exhibit A-1 (Project Area) and develop a
Project topographic base map to District standards. Depict all man-made and natural features
necessary for Project design and provide accurate and representative one-foot ground

Area, including placing survey control, locating structures, and creek cross-sectional data. In
addition to District survey work, Washington County (County) has performed survey work
along Jenkins road and SW 153rd Drive. Consultant shall integrate previous survey efforts
and combine them on the topographic base map to form a single comprehensive map all on
the same horizontal and vertical coordinate system. This may require Consultant to transpose
previous survey efforts.

during field investigations. Seek clarification from the appropriate utility owner and advise
the District Project Manager if omissions or discrepancies are noted in the field.
5. Survey Control Network: Establish a network of horizontal and vertical survey control
throughout the Project Area. This network shall incorporate control from previous survey
efforts to serve as a baseline to transpose previous survey information. Install all control
monumentation to withstand movement and/or deterioration by seasonal weather influences

disturbance by construction activities and allow for easy location and recovery at a later
date. Reference, horizontally and vertically, all field survey information collected to the base
control network. Provide a list of computed XYZ coordinates with descriptions for all
control points, survey points, and property monuments associated with the surveys to
District.

approximately 800- to 1,000-ft increments to obtain information for design and
construction of the gravity sewer. Conduct two additional borings at each
trenchless crossing (TriMet, Reser’s bridge) at both receiving and boring pit
locations. The borings will generally extend to at least 10 feet below the
anticipated invert of the proposed sewer pipe.
19-083 Exhibit A – Scope of Work
Page 9
Place a vibrating wire in four boreholes to permit measurement of the depth to
groundwater. The piezometer cables will be protected at the ground surface with
a metal monument. At least three measurements of ground water shall be made,
one at the initial installation, one during low water summer conditions, and one
during the winter with wet conditions.
b. Drilling and Sampling. Borings shall be made with a track-mounted drill rig, if
possible. If not possible, boring shall be made with a man-power maneuverable
drill rig capable of attaining a bore depth of 25 feet below grade. Borings will be
made with solid-stem or hollow-stem drilling methods. Borings made in
pavement may be made with either mud-rotary or hollow-stem auger drilling
techniques. Disturbed split-spoon samples and undisturbed Shelby tube samples
of soil will be obtained from the borings at about 2.5-feet intervals of depth in the
upper 15 feet and 5-feet intervals of depth below a depth of 15 ft. The Standard
Penetration Test will be conducted while the disturbed split-spoon samples are
being taken. Rock, if encountered, shall be continuously cored, particularly if it is
within the depth of planned excavation.
The drilling spoils from borings will be placed in metal drums and removed from
the site. Bore holes will be backfilled with bentonite chips in natural areas. Where
borings penetrate pavement, the existing pavement section shall be restored and
bore hole backfilled with grout.
The borings will be subcontracted to a drilling contractor experienced in drilling
and sampling soils for engineering purposes. The drilling and sampling will be
accomplished under the direction of a geotechnical engineer or engineering
geologist licensed in the State of Oregon who will maintain a detailed log of the
materials and conditions uncovered during the course of drilling and sampling.
All borings will be constructed, reported to Oregon Water Resources Department
(ORWD), and abandoned per the requirements of OAR 690-240, including
piezometers.
All boring located within regulated wetlands will be properly permitted prior to
commencement of the work. Consultant shall coordinate with and support District
staffs’ efforts in obtaining necessary general authorizations from permitting
agencies to facilitate investigations.
Access. Drilling shall be performed during the drier late spring or summer
months when access can be readily made. Consultant along with the geotechnical
engineer or geologist in charge of the drilling operation shall meet with the
District and Property owners in the field to identify drilling locations prior to
developing an exploration work plan. When required, this work plan shall also be
submitted to Washington County in order to obtain the required permits to work
in the right-of-way prior to the commencement of field work. The exploration
work plan memorandum for the planned work will include a scope of work,
drilling and sampling procedures, access routes, working areas and bore locations,
19-083 Exhibit A – Scope of Work

wetlands/waters, trails, and a site health and safety plan.
Consultant shall obtain any necessary permits from the County for shoulder and
lane closures required for the drilling work along with any necessary flagging or
traffic control. District will manage permitting for regulated wetlands and will
acquire necessary site access permission based upon the approved exploration
work plan.
c. Utility Locates and Notifications. A request to the Utility Notification Center
will be made at least 48 hours prior to the start of drilling. Appropriate timely
notifications will be made to the District, Washington County, and others as
required prior to the start of work. A private utility locator will also be used to
clear the borings.
2. Conduct laboratory tests to provide data on the important physical characteristics of the
subsoils, essential for engineering studies and analyses. The laboratory tests will include
standard classification tests, such as natural water content, washed sieve analyses, and
unit weight determinations, as well as strength and consolidation testing. Perform rock
core strength tests where suitable rock core samples are obtained.
3. Conduct engineering studies and analyses. Prepare conclusions and recommendations
