Attention: Mr. David Gierach, P.E.
Subject: Budget Estimate for Subsurface Soil Exploration
City of Sanford Westerly Interceptor
Dear Mr. Gierach:
As you requested, we are pleased to present the following budget estimate for
conducting a subsurface soil exploration for your Westerly Interceptor Project.
Based on a preliminary site plan which you have supplied, the proposed gravity
lines (18", 24" and 30") and force main (12" and 14") are approximately 16,000 feet
long. You indicated cover for the force main was approximately 3 feet, and 10 to
15 feet for the gravity lines. In addition, the project includes a lift station 20 feet
in depth.
The scope of our work will include determining if the bearing capacity and other
soil characteristics are suitable to construct the proposed lift station and to
provide pipeline compaction recommendations.
The budget estimate to provide a soils report for the aforementioned project is
approximately $5,000.00. Coordination of boring locations with utility companies
will be necessary and has been included in the above estimate. Soil borings for the
reclaimed water lines were not been included in our cost as you requested.
We appreciate the opportunity to submit this budget estimate and look forward to
working with you on this project. We would be pleased to provide a more detailed
cost breakdown when the project further developes.
Very truly yours,
ARDAMAN & ASSOCIATES, INC. ~.E."'

FOR
PLANNING FOR THE FIRST PHASE
OF THE
WESTERLY INTERCEPTOR SEWER
FOR THE CITY OF SANFORD
This Amendment, dated this 29th day of June, in the year
Nineteen Hundred and Eighty-Eight and between the CITY OF
SANFORD, FLORIDA (hereinafter called the OWNER, and CONKLIN,
PORTER a HOLMES - ENGINEERS, INC. (hereinafter called the
ENGINEER), is ~utually agreed upon and declared an authorized
Amendment to an Agreement dated December 71 1983, between the
parties, herein setting forth the scope, terms and conditions of
the work herein authorized.
I. GENERAL
The City of Sanford has requested a proposal to perform a
preliminary planning analysis of a westerly interceptor sewer,
which would extend westward from the wastewater treatment plant
to the general vicinity of the planned Smith Canal northerly
extension.
II. SERVICES HEREIN TO BE PROVIDED
The engineering services to be provided under this Amendment are
covered in our Agreement with the City for Consulting Services,
dated December 7, 1983, under "Additional Services of the
Engineer"~ Section 3.1.2, and are described as follows:
A. Review with the City the boundaries of the planning area to
the west. Develop and refine a study base map.
B. Divide the study area into topographical major drainage
areas showing basic drainage divides, streams, ditches,
ponds and outlets; further subdivide the major areas into
smaller sub-drainage basins or areas.
C. Review aerials, flood plain maps, soils and vegetative maps,
and determine areas that are not likely to be suitable for
development. Cursory field inspections to verify
conditions. Place areas on the base map.
D. Review the City's latest population and land use projections
for the planning area. Follow up with other agencies,
developers, and industries on additional data needed.
Obtain their plans for future growth, if available. Project
10 and 20 year growth using available sources and
information from A, B, and C above. Analyze maximum
build-out utilizing current land use density projections as
the long-range planning requirement.. Distribute
projections to topographical areas.
E. Examine existing conveyances and the capacities of those
pipelines. Evaluate existing flow rates and estimate
reserve capacity available, consult with City staff to
determine age, type of materials, condition, useful life,
O & M benefits and liabilities, and desirability for
expansion of existing facilities.
F. Project wastewater flows from various subdivisions of the
westerly planning area. Develop estimates of wastewater
flows on average and peak bases for the subdivided areas of
the planning area.
G. Sketch alternative locations for the westerly interceptor
line, i.e. whether it should be along the Narcissus Road
right-of-way, or along S.R. 46. Establish points of sewage
flow entry to estimate line sizes for planning purposes.
Local sewer service will not be planned.
identify advantages and disadvantages of the two alternative
locations for the westerly interceptor.
I. Identify locations and costs of area lift stations to pump
to. the higher elevation alternative if the interceptor were
to be located along S.R. 46.
J. Identify planning type probable costs of the alternative
westerly interceptor locations and types, i.e. whether they
would be gravity sewers or force mains.
K. Consider and evaluate implementation requirements, including
right-of-way acquisition, permitting, funding,
jurisdictional matters, etc. Select a recommended plan
along with Owner and consider phased implementation of the
long range plan.
L. Consider and evaluate construction of the reclaimed water
line within the same trench as the selected alternative.
Estimate the line size of the reclaimed water system and
estimate the installation date after discussion with City
staff.
M. Prepare a preliminary report in draft form with text, maps,
and estimates summarizing the Study, its results, and
recommendations, and submit to the City.
N. Make revisions and refinements to report after Owner's
review, and furnish 15 copies to Owner.
O. Present summary of report to City Commission at work session
and discuss and answer questions.
AUTHORIZATION OF SERVICES AND PAYMENTS TO THE ENGINEER
It is the intent of this Agreement that upon execution of the
same, all services herein are authorized to be performed.
For the performance of the Scope of Work described herein,
payment to the ENGINEER by the Owner shall be on the basis of
cost times a multiplier, in accordance with Section 5 entitled
"METHOD OF PAYMENT TO THE ENGINEER" of the Agreement dated
Lecember 7, 1983, except that the current fringe benefit factor
is 1.4487. The payroll cost multiplier shall be 2.10.
The estimated not-to-exceed fee for the work herein authorized
is $20,400.00, including those services listed in the attached
Plan of Study.
IN WITNESS WHEREOF, the 1parties have caused this Amendment
to be executed as of the day and year hereinabove set forth.
