Amendment No 13 to Brown and Caldwell Agreement, 06 -01
SCOPE OF SERVICES RELATED TO
PHASE 1 DESIGN SERVICES
FOR THE
PORT ANGELES CSO IMPROVEMENT PROGRAM
EXHIBIT A
To Amendment 13
PROFESSIONAL SERVICES AGREEMENT NO. 06 -01
Amendment 13 provides new scope of services and additional budget for work to be performed
under the Phase 1 Design Services for the City of Port Angeles (City) CSO Improvement Program.
This amendment provides for engineering services to allow the City to develop contracting
documents for repair and maintenance of the Port Angeles Industrial Outfall Diffuser in order to
prepare the outfall for City service. Prior underwater inspections determined that 4 diffusers (of 48)
were broken, and at several seafloor sediment had entered and partially blocked the outfall pipeline.
In addition, use of the high capacity diffuser system could allow salt water intrusion at the lower,
normal City flows to such an extent that modifications may be needed to mitigate this effect. The
City intends to award the construction contract for the Port Angeles Industrial Outfall Diffuser Repair
and Maintenance Project to a qualified marine contractor having requisite experience, equipment,
and dive tending capabilities. The construction contract will provide for repair or capping of broken
diffusers, modification of diffuser ports to aid in distribution of flow under flow rates ranging from 2
to 50 mgd and for cleaning and disposal of sediments removed from the diffuser section of the
outfall pipeline. The CSO Phase 1 Joint Aquatic Resources Permit Application (JARPA) provides for
U.S. Army Corps of Engineers Section 404, Washington Department of Ecology (Ecology) 401 Water
Quality Certification, and Washington Department of Fish and Wildlife (WDFW) Hydraulic Project
Approval (HPA) review and approval of the work contemplated for preparing the industrial outfall for
City service.
Subtask 17.1 Diffuser Repair and Modification Development and Evaluation
Brown and Caldwell will develop diffuser repairs, modifications, and cleaning approaches through
diffuser hydraulic modeling, consultation with marine contractors, and knowledge of similar CSO
outfalls in Puget Sound and other locations.
Activities:
1. Discuss marine outfall repair possibilities with two local Pacific Northwest marine
contractors. Discuss limits of work that can be completed by divers, such as entry into
submerged 36-48- inch diameter pipe for sediment removal, access to riser connections on
diffuser pipe, available tools, and for other repair and maintenance activities.
2. Complete hydraulic modeling of diffuser based on repair options developed by Brown and
Caldwell in order to optimize /balance the following:
a. Flow distribution between ports under a range of design flows (2 to 50 mgd).
b. Headloss through the diffuser.

CSO Phase I Project

c. Whether risers require restoration versus "blinding i.e. capping.
3. Evaluate number, size, backpressure and other design criteria of elastomeric duckbill check
valves to be used for diffuser port modification.
4. Evaluate effect of identified repairs and modifications on the overall outfall hydraulic grade
line at the Effluent Diversion Structure under high tide conditions.
5. Identify combined CSO bypass +WWTP flow and tide elevation at which diversions will occur
from the Industrial Outfall to the City Outfall based on the identified Industrial outfall diffuser
repairs and modifications.
Assumptions:
1. Hydrodynamic modeling and water quality reasonable potential analyses will not be
performed. It is assumed that a uniform flow distribution can be achieved through the
Industrial Outfall at peak day and maximum month WWTP flows with the recommended
repairs and modifications under non -CSO flow conditions. Dilution ratios will be assumed to
be equivalent to or increase by virtue of switching the discharge from the City Outfall to the
Industrial Outfall (deeper discharge, greater diffuser length, and stronger ambient currents).
2. Diffuser hydraulic performance will be predicted using one of Brown and Caldwell's
proprietary programs for diffuser hydraulics (DIFF$$ or DIFFZ, developed from the methods
presented in Chapter 10 of Mixing in Inland and Coastal Water Waters, H.B. Fischer, et al,
Academic Press, 1979) using existing diffuser drawings from the former Rayonier Mill and
information gathered from the Cosmopolitan Engineering underwater inspections.
Deliverables:
1. Summary memorandum describing 1) findings of research; 2). hydraulic evaluations; and 3).
proposed repair, modification and cleaning requirements for contracting.
Subtask 17.2 Design Preparation Bidding Documents
The City of Port Angeles intends to prepare bidding documents for the Industrial Outfall Diffuser
Repair and Cleaning Project with Brown and Caldwell support as follows:
Activities and Assumptions:
1. Brown and Caldwell will prepare technical contents to support City development of bidding
documents consisting of:
a. Technical Specifications
b. Project size Plans
2. Technical Specifications will consist of identifying, describing, and specifying the contract
requirements for cleaning, repairing, and modifying the Industrial Outfall and for materials to
be incorporated into the diffuser modifications and repair.
3. Up to three plan sheets consisting of the following:
a. Cover Sheet /Area Map Outfall Coordinates
b. Diffuser Plan and Profile
c. Repair Details /Port Details

4. Brown and Caldwell will prepare and submit for review to the City and Washington State
Department of Ecology preliminary plans and technical specifications at an approximately
80% 90% completion level.
5. Brown and Caldwell will prepare an Engineer's Opinion of Probable Construction Cost
Estimate at an approximately 80 90% completion level. City will deliver a complete
electronic copy of the draft Project Manual to Brown and Caldwell to provide context on the
overall project for which the Opinion of Probable Construction Cost will be prepared.
6. Plans, Technical Specifications, and Opinion of Probable Construction Cost will be finalized
based on City and Ecology review comments. Brown and Caldwell will address comments
related to the technical portions of the work. City will address comments related to the
bidding, contracting, general and supplementary requirements, and special provisions.
7. City will submit final bidding (100 documents to Ecology for final review and approval.
Deliverables:
1. Engineer's Opinion of Probable Construction Cost.
2. Electronic originals of Preliminary and Final Bid Ready Plans (1/2 size) and Technical
Specifications for City's insertion in a Project Manual.
Subtask 18.2.Assistance During Bidding and Construction
