EXHIBIT A
SCOPE OF WORK
Cedar Street Retaining Wall
PROJECT ABSTRACT
This project includes the repair and or replacement of an existing retaining wall and an
additive item for new sidewalk construction located in the 200 Block of Cedar Street in
the City of Port Angeles
TASK 1 - WALL EVALUATION (Completed & Report Available)
The existing wall shall be evaluated to determine the extent of corrosion, condition of
the tie-back anchors and timber retaining structure, at a minimum by:
1) Perform ultrasonic thickness measurements on a sufficient number of fascias to
determine if the product will function as originally specified. A sub-consultant
who specializes in corrosion will perform this work. The local contractor will
provide a means (a lift) to get to the facing panels for the non-destructive testing.
2) Physical examination of exposed components will be performed after hiring a
local contractor to remove the wall panels. The local contractor shall provide
temporary barriers to protect both the lower street and upper areas until a
decision is made on the final design. This may be replacing the fascia after
testing the tiebacks.
3) Determine if the tie back and soldier pile system is sufficient for further use by
examining the steel and possibly stressing one or more tieback members in the
exposed sections. The local contractor will perform this task under our
monitoring.
4) Evaluate the corrosion source: check for stray currents or similar natural systems
that caused the corrosion. Also, obtain data for new design so as to avoid this
problem in future.
The Consultant will prepare a report detailing examination findings and
recommendations for wall repair or replacement. This will include the corrosion
subconsultant's report, a structure evaluation of the existing structure (by a licensed
structural engineer) and cost analysis of possible improvements.
Our report will include;
1. Field report with photos,
2. Corrosion report of existing system and recommendations for protection of new
system,
3. Structural Analysis of existing wall system (including geotechnical loading and
structural calculations),
4. Recommendations for repair with preliminary design sketches,
5. Engineering level cost estimates of the repair options.
TASK 2 - WALL REPAIR/REPLACEMENT & ADDITIVE SIDEWALK
The Consultant shall prepare plans and special provisions for project manual for repair
or replacement of the wall as determined in Task 1, and additive items for new sidewalk.
Based on a meeting with the City Public Works staff, the design will be limited to

decisions for the project improvements based on criteria provided by
the CITY. The preliminary design shall include fifty (50%) percent
plans, typical sections, horizontal and vertical alignment, and other
information required to delineate the project improvements.
1. Preliminary Design - 90%
Prepare ninety percent (90%) plans, specifications and Engineer's
estimate incorporating CITY's fifty percent (50%) comments for further
review and comments.
2. Final PS&E - 100%
Prepare one (1) set of final plans (full size and half size), specifications, and
Engineer's estimate incorporating CITY's 90% comments. Plans shall be on
both reproducible mylar and in AUTOCAD drawing format on a disc or CD.
The CONSULTANT shall also provide an equal number of revised plans if
further review discloses additional revisions are necessary.

TASK 1 - WALL EVALUATION (Completed & Report Available)
Includes Field Work, Travel, Office Analysis and Report Preparation; the total cost,
including the local contractor and our subconsultant Norton Corrosion, is estimated to
be $32,100. This will be a maximum not to exceed fee and we will invoice you for only

3. Structural analysis of wall system,
4. Recommendations for repair with preliminary design sketches,
5. Engineering level cost estimates of the repair options.
TASK 2 (2.3) - WALL REPAIR I REPLACEMENT & ADDITIVE SIDEWALK
The design and preparation of bid documents will be to remove and replace the
corroded facing stringers (reuse the non-corroded members), remove backfill, build
additive sidewalk per City's length and standards, clean up, phase or stage the work so
as not to disrupt traffic, replace backfill or new backfill, add appropriate corrosion
protection to lengthen wall life, and replace or change drainage at top.
Sheet count as follows:
. Cover sheet wI location, abbreviations and table of contents.
. 1 - plan profile sheet of wall area only at 20' scale.
. 1 - plan sheet of whole alignment (showing full walk) at 50' scale.
. 2 to 3 sheets of details of existing conditions and new designs.
. 2 to 3 sheets with title and notes & specifications - (The 11 x17 size requires
more sheets to get enough space.
Package will be between 7 and 9 sheets at 11 by 17 size (D-size).
Based on our meeting with the City, MPA estimates our fee would be $18,500 to
complete the design. This includes preliminary planning, another site visit, the
document preparation and changes after review, and a fee for several days of
consulting by Norton Corrosion as to the details of anode placement etc.
TASK 2.4 - CONSTRUCTION MONITORING
This task is difficult to estimate since we do not know the duration, but our goal
would be to staff the work with a staff engineer where they are on site or traveling
for a maximum of approximately 50 hours per week. In addition, approximately 8
hours per week should be allocated for a senior or principal to visit the site once

during construction and keep track of the work from the office. This labor cost is
approx. $4500/week + per diem & travel costs.
Based on experience, MPA would estimate about 4 weeks of our involvement.
This equates to a fee of approximately $23,000.
Milbor-Pita's 2005 Overhead & labor rates
MPA's overhead rate is 170% and we typically work at a 10% profit.
Our hourly rates per grade level at the above rates are as follows:
. Principal = $135.88
. Senior Engineer = $118.80
. Senior Staff Engineer = $100.98
. Staff Engineer = $74.25
MPA adds a 10% mark up on subconsultant fees.
