responsibility to visit the construction site to become familiar with the
progress or quality of the completed work on the PROJECT or to determine,
in general, if the work on the PROJECT is being performed in a manner
indicating that the PROJECT, when completed, will be in accordance with
the Contract Documents, nor shall anything in the Contract Documents or
the agreement between CITY and ENGINEER be construed as requiring
ENGINEER to make exhaustive or continuous on-site inspections to
discover latent defects in the work or otherwise check the quality or quantity
of the work on the PROJECT. If, for any reason, the ENGINEER should
make an on-site observation(s), on the basis of such on-site observations, if
any, the ENGINEER shall endeavor to keep the CITY informed of any
deviation from the Contract Documents coming to the actual notice of
ENGINEER regarding the PROJECT.
(3) When professional certification of performance or characteristics of
materials, systems or equipment is reasonably required to perform the

to rely upon such certification to establish materials, systems or equipment
and performance criteria to be required in the Contract Documents.
F. Opinions of Probable Cost, Financial Considerations, and Schedules
(1) The ENGINEER shall provide opinions of probable costs based on the
current available information at the time of preparation, in accordance with
Attachment A.

maintenance costs; competitive bidding procedures and market conditions;
time or quality of performance by third parties; quality, type, management,
or direction of operating personnel; and other economic and operational
factors that may materially affect the ultimate PROJECT cost or schedule.
Therefore, the ENGINEER makes no warranty that the CITY's actual
PROJECT costs, financial aspects, economic feasibility, or schedules will
not vary from the ENGINEER's opinions, analyses, projections, or
estimates.
G. Construction Progress Payments
Recommendations by the ENGINEER to the CITY for periodic construction
progress payments to the construction contractor will be based on the
ENGINEER's knowledge, information, and belief from selective sampling and
observation that the work has progressed to the point indicated. Such
recommendations do not represent that continuous or detailed examinations have
been made by the ENGINEER to ascertain that the construction contractor has
completed the work in exact accordance with the Contract Documents; that the
final work will be acceptable in all respects; that the ENGINEER has made an
examination to ascertain how or for what purpose the construction contractor has
used the moneys paid; that title to any of the work, materials, or equipment has
passed to the CITY free and clear of liens, claims, security interests, or
encumbrances; or that there are not other matters at issue between the CITY and
the construction contractor that affect the amount that should be paid.
H. Record Drawings
Record drawings, if required, will be prepared, in part, on the basis of information
compiled and furnished by others, and may not always represent the exact

LOG NAME: 60INTERCEPTOR REFERENCE NO.: **C-20347
SUBJECT:
Engineering Agreement with Malcolm Pirnie, Inc. for the Village Creek Interceptor Pilot Study
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute an engineering agreement
with Malcolm Pirnie, Inc. for the Village Creek Interceptor Pilot Study, for a total fee not to exceed $92,316.
DISCUSSION:
On April 9, 2002 (M&C C-19043), the City Council authorized the execution of an engineering agreement
with Malcolm Pirnie, Inc. for the Village Creek Wastewater Treatment Plant Corrosion Study and Odor
Control Master Plan. This agreement included the evaluation of corrosion at plant influent structures and
the incoming 90/96-inch sewer interceptor lines and the development of an odor control master plan.
The limited inspection of the influent 90/96-inch sewer interceptor lines shows extensive corrosion damage
in the vicinity of the manhole structures. However, as corrosive gases (hydrogen sulfide) are normally more
concentrated at the manhole structures, there was no indication whether the entire sewer line had corrosion
damage. This pilot study will look at several random sections of the 90/96-inch sewer interceptor lines to
determine the areas and limits of corrosion damage.
As part of this pilot study, the engineer will inspect 5 key sections of the influent 90/96-inch sewer
interceptor lines using a proprietary sonar system (Sonex). This system will map the levels of corrosion
within the sewer line sections and correlate it with the previous data to provide an approximate indication of
the level of corrosion on the influent sewer interceptor lines from the old Riverside Wastewater Treatment
Plant (Greenway Park area) to the Village Creek Wastewater Treatment Plant.
This project is located in COUNCIL DISTRICTS 4 and 5.
A waiver of the MIWBE Ordinance requirement was requested by the Water Department for this project and
approved by the M/WBE Office.
FISCAL INFORMATION/CERTIFICATION:
The Finance Director certifies that funds are available in the current capital budget, as appropriated, of the
Commercial Paper Sewer Fund.
