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

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.

19-083 Exhibit A – Scope of Work

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.

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,

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.
