ADDmONAL SERVICES PROPOSAL
NORTHSHORE STREETSCAPE PROJECf
SANITARY SEWER REHABILITATION
The 'following scope outlines the engineering design services required to prepare detailed plans
and specifications for rehabilitation of the sanitary sewer system within the No~ore
Streetscape project in Miami Beach. The plans and specifications will include those portions
of the system recommended for rehabilitation by the report titled "Results of Television
Inspection and Smoke Testing of the Sanitary Sewer Collection System - Northshore
Streetscape Project".
TASK 1 - SURVEY
Using a subconsultant, we will survey sanitary manhole tops and invert elevations of the
portions of that sanitary sewer recommended for rehabilitation and storm sewer grates and
invert elevations of storm pipe shown to cross or contlict with the sanitary sewer. Only storm
sewer elevations not obtained in previous surveys for the North Beach project will be surveyed.
This information is critical to providing contractors with plans that give enough information
to bid any of a number of repair techniques including, replacement or slip lining. The ability
to receive bids on alternate repair methods tends to make the bidding more competitive and is
therefore to the City's advantage.
TASK 2 - REPAIRlRERABILITATION DESIGN - PREPARATION OF PLANS AND
SPECIFICATIONS
Using the aforementioned report as a starting point and by meeting with City staff to disc~s
the recommendations, we will finalize the rehabilitation and repair program, prepare plans and
specification for the repairs and coordinate with the ongoing streetscape design. The scope and
fee associated with preparation of plans and specifications anticipates up to 2S plan and profile
sheets and up to S detail sheets. The plan and profile sheets will include known utilities in
plan view and known utilities that would impact reconstruction at the sanitary sewer shown in
profile. Up to 3 progress meetings with the City will be held during the design process.
Periodic meetings to coordinate the sanitary repairs with the streetscape project will also be
conducted internally. The technical specifications will include several repair and rehabilitative
techniques that are applicable to this specific project. It is anticipated that technical
specifications will be included for replacement, point repairs, slip lining, joint grouting, lateral
grouting, inversion lining and manhole rehabilitation and manhole frame cover replacement.

.
No corrections to defects on private property are proposed to be included. However, if the
City wishes to correct defects on private property, scope to design the COrrectioDS could be
added to this proposal. This proposal assumes that the City will require owners of properties
with sanitary defects to comet them at their own cost.
TASK 3 - PREPARE SPECD'ICATIONS
We will pre.-e specifications 10 that the SlIIIitary rehab work can be bid along with the
streetscape project. Completing the sanitary work under the same general contractor as the
streetscape project will provide the City with better conttol over scheduling and will avoid the
possibility of one contractor C811-'nl delays to another and looldng to the City for restitution.
TASK 4 - QUALITY PROGRAM
An active prosram of quality checks will be conducted by senior team members at several
points during the design process and prior to the documents being released for bid.
TASK 5 - BID PROCESS
We will answer contractor's questions during the bid process, tabulate the sanitary sewer
rehabilitation portion of the bids, evaluate the proposed rehabilitation technique along with the
bid price and provide input for recommendation of award of the construction contract.
TASK 6 - CONSTRUcnON PHASE SERVICES
We will provide construction phase services for the sanitary sewer rehabilitation. A specific
scope and fee associated with the services will be provided at a later date.

Members of the City Commission
DATE: November 17, 1993
FROM:
SUBJECT:
NORTH SHORE STREETSCAPE PROJECT, SANITARY SEWER
SYSTEM REPAIR, KIMLEY.HORN & ASSOCIATES, INC., CONTRACT
AMENDMENT.
ADMINISTRATION RECOMMENDATION:
The Administration recommends the City Commission approve an increase to the Kimley-
Horn & Associates, Inc., contract by an amount not to exceed $83,900. Fees proposed
within the individual tasks cannot be exceeded without prior approval of the City
Commission and in no case exceed the total fee. This is to provide engineering services
for completion of plans, specifications, and contract documents for the remedial work to
the Sanitary ~wer System, located within the North Shore Streetscape Project. The work
will be done in accordance with the recommendation of the report titled "Results of
Television Inspection and Smoke Testing of the Sanitary Sewer Collection System. North
Shore Streetscape Project."
BACKGROUND
On June 16, 1993, the City Commission authorized entering into a contract with Kimley-
Horn & Associates, Inc., to do a sanitary sewer evaluation study for the sanitary sewers
within the limits of the North Shore Streetscape Project. Even though the City is
implementing a City-wide infiltration and inflow study, this segment was authorized in
advance so that remedial improvements to the sanitary system could be made as part of or
in advance of the North Shore Streetscape Project.
REPORT SUMMARY
.
The purpose of the report was to evaluate and determine the conditions of the Sanitary
Sewer System and to present recommendation alternatives and cost estimates to rectify
identified defects. The study area (North Shore Streetscape Project) was estimated to
contain 15,000 ljnear feet of sanitary sewer. As part of the field studies, 147 manholes were
inspected, sewet lines were hydraulically cleaned and inspected internally with closed circuit
television equipment, and sewer lines and laterals were smoke tested to identify inflow
sources.

Data obtained from the studies identified 0.188 million gallons per day (MGD) from
infiltration (seepage into the systems through bad joint, broken sewers, which occurs
continuously) and 0.66 MGD of inflow (illegal connections from clean outer area drains
and manhole defects, which occurs during rain fall events. For the purpose of the analysis,
we have assumed a 25% occurrence).
Based on analysis of each line segment and each manhole, rehabilitation alternatives and
limits of cost effectiveness were developed. The rehabilitation recommendations include
the replacement and relining of select line segments, rehabilitation of all manholes and
disconnection of storm water inflow connections.
The recommended rehabilitation will remove 0.659 MGD (Million Gallons per Day) of
inflows during rain events and 0.152 MGD of infiltration continuously. The combined
removal equates to 1055 new connections based on an average contribution of 300 GPO
per service. DERM has indicated a credit of 1 to 5, which translates to 211 new services
for future construction credits.
FINANCIAL ANALYSIS
It is estimated that the recommended improvements will eliminate 0.811 MGD from the
sanitary system. Based on an average sewage treatment cost (wet and dry season rates) of
$0.9811 per thousand gallons, this equates to a savings of $311 per day or $113,515 per
year.
The total estimated cost of rehabilitation in. the study area is $755,000. This includes
contingencies for unforseen occurrences. Therefore, the estimated pay-back for this project
is approximately seven years without considering the positive environmental benefits and
the impact on the sewer moratorium. Funding will be advanced from water operation and
maintenance funds and reimbursed from a bond issue for this purpose.
CONCLUSION
The attached proposal from Kimley-Hom & Associates, Inc., outlines the scope of services
in five tasks. Fees proposed within the individual tasks cannot be exceeded without prior
approval of the City Commission and in no case exceed the total fee. Task 6: Construction
Phase Services will be carried out by City Engineering staff as proposed in the 1993/94
budget. The consultant will prepare the contract document to provide bids for alternate
methods of construction. This will require appropriate specifications and additional plan
details for each method to insure the most cost effective method of construction used. Staff
has reviewed the proposed fee schedule and determined it to be reasonable.
It is recommended tbat the City Commission authorize proceeding with the work as
reCommended in the Kimley-Horn & Associates, Inc., report and authorize the contract
amendment to provide engineering services as outlined herein.
