Reference: Sandy Lake Road Design Revisions
Dear Mr. Griffin:
Jacobs is pleased to present you with our proposed fee estimate and scope of work description for additional
design work on Sandy Lake Rd. We have revised the fee estimate and scope of work to reflect the items
that were discussed back in March as well as the additional items that were added to the scope during a
meeting at the City offices on June 19' 2003.
We have broken the design fee into multiple parts. The first part includes the basic or miscellaneous design
changes. The second part includes the work to generate record drawings. The third section includes the
work to redesign the roadway width to 27' back to back of curb. The fourth section includes the work to
lower the profile of the roadway to meet ONCOR's elevation requirements. Additionally, a separate breakout
is shown for the administrative time that will need to be added to whichever design option(s) is/are agreed
upon.
In reference to the 27' vs. 28' design change, our records show that the roadway immediately to the west of
our section (the eastern half of the MacArthur/Sandy Lake intersection) was designed as 28' back to back of
curb. If it was built at 28' back to back, then perhaps our section should remain as currently designed, 28'
back to back of curb. The amount of time and money (see attached fee schedule, Option 2) that is needed
to revise all the drawings which are affected by this 1' design change are extremely high. Our suggestion is
that The City reevaluate this design revision request and leave the typical section at 28' as currently
designed.
This fee estimate is based on our recent discussions and evaluation of the detailed scope of work. Our fees
will be billed out to the City as time & material not to exceed the total values shown on the "Fee Estimate for
Sandy Lake Rd Revisions". We will forward a copy of Jacobs' standard contract agreement for your review
as well.
We look forward to your response as to which of the design options the City would like to pursue with Jacobs
Civil Inc. Please do not hesitate to contact me at 214-424-7579.
Sincerely,
Debbie Kiger, P.E.

DESIGN SCOPE OF WORK
Revised July 7, 2003
Sidewalk
· Jacobs will show the proposed sidewalk, located 5' from the back of curb, on the
entire south side of the project.
· Jacobs will revise the grading (cross sections) at the right turn lane onto Riverchase,
as there isn't enough flat grade there for the sidewalk.
Drainage at Riverchase
· The drainage area map and hydraulic computations will not be revised.
· The cross sections will not be revised.
· Jacobs will take the existing drainage pipe to the south as well as a newly constructed
pipe from the east and tie them into the Sandy Lake Rd system.
· Jacobs will provide new field survey to locate the two new pipes that will be tied into
the Sandy Lake Rd storm sewer system.
Storm line - vs - Utility Encasement
Pot Holes for Utilities
· These issues will be handled as added specification items and bid items on the
quantity list, but not called out on the plan set. Jacobs will provide an estimated
quantity for each of these items and list it on the quantity summary sheet.
· The City will provide a description in the specifications so that the work included in
each bid item is defined.
Sprinkler Conduit/Pipes
· The City will provide to Jacobs a marked up set or other information from the City's
Park Department as to the location, size, type, and taps necessary for the sprinkler
conduit (irrigation).
· Jacobs will (1) add symbology and notes on the plan & profile sheets, (2) revise the
quantity and call outs of conduit lines shown on the typical roadway sections, based
on the information provided by the Parks Department.
· Jacobs will indicate the location of the power supply for the irrigation, interconnect
wiring and street lights. This includes a site visit to determine locations of existing
items as well as coordination phone calls with TXU. Jacobs will not be responsible
for the lighting design, just the median conduits and general location of the TXU
lighting foundations.
· Jacobs will not show the irrigation design, just the basic piping in the median.
HC Ramps
· Jacobs will include the City of Dallas Detail 9006, 251D in the plan set, which does
meet the newest ADA standards. The details to be shown include cross slopes,
running slopes, color barrier between ramp/crosswalk and pedestrian pads at the
signal lights.
,, Jacobs will modify the plan set HC ramps if they do not meet the newest ADA
standards/locations.
· Jacobs will modify the crosswalks and median noses to meet the new ramp locations
if necessary.
· Jacobs will submit the plans for the TAS review to an approved independent agency.
The fee involved for the independent review is included in the direct costs portion of
the fee estimate.
Lower the Profile of Sandy Lake Rd.
· After coordinating with Jon Scarborough on behalf of ONCOR, Jacobs will lower
part of the profile of Sandy Lake Rd. to accommodate the necessary clearance under
the transmission lines (located approximately sta 45+00 to sta 50+00, just west of
Riverchase Dr). ONCOR has stated that they estimate the proposed clearance to be
21.5'; they requested a minimum clearance of 22'; they would prefer to have a
clearance of 23'. Therefore, lowering of the profile 1.5' maximum is proposed.
If the lowering of the roadway interferes with the existing floodplain elevations,
Jacobs will not perform any tasks to request a revision to the floodplain maps.
The drainage area map and hydraulic computations will not be revised.
Jacobs will relocate the drainage structures to the new low points in the roadway.
Miscellaneous Revisions
· The City will modify the specification document and tailor the pay item descriptions
to meet the City's requirements. Jacobs will only provide accurate quantities for the
pay items. Jacobs' engineers will not sign & seal the specification document.
· Jacobs will verify that the Dallas County information (COUNTY OFFICIALS) is
correct, as shown on the cover sheet of the plan set.
· Jacobs will provide to the City 30 sets of full size plans (bond) for bidding purposes.
Jacobs will then provide to the City 9 sets of full size plans (bond) for the
construction phase.
Jacobs will not develop the complete NOI or SW3P. The selected contractor will
prepare the NOI and SW3P.
The City will provide to Jacobs a complete set of red lined drawings at the conclusion
of the construction. Jacobs will incorporate the red-lined revisions into the
documents as the final record drawing plan set and provide them to The City. Jacobs'
engineers will not sign & seal the record drawings.
The City wants the proposed roadway width to be revised from 28' to 27' wide.
Jacobs will survey the adjoining section immediately to the west of the start of this
section to verify widths and locations of curbs, etc. Jacobs will revise all the plans
which are affected by this change. These include the quantities, traffic control plans,
typical sections, paving plan & profile sheets, striping plan, storm drain plan &
profile sheets, hydraulic computations, storm drain laterals, traffic signal plans,
culvert and retaining wall plans and all cross sections to reflect the change in roadway
width.
· Jacobs will have a surveyor subcontractor set eight (8) new and permanent horizontal
and vertical control points. Jacobs will then revise the horizontal/vertical control plan
sheet. The points need to be set outside of the construction limits and needs to be
done prior to the utility relocations beginning.
,, Jacobs will coordinate with Oncor to obtain the correct streettight foundation detail,
which will be included in the plan set. Note 3 on the paving plan & profile sheets
will be revised to show that Oncor's foundation detail will be used.
· Jacobs will have the surveyor subcontractor update the parcel ownership call outs as
follows: parcel 8 - St Josephs, parcel 14 - King, parcel 19 - TXU, parcel 20 - Terra
Corp, JV, parcel 27 - Thompson, Kimbrel, Moore.
· Jacobs will show a note that reads "Remove fire hydrant and Replace with new
hydrant behind proposed curb" at sta. 37+40 and sta. 42+40. Jacobs will show the
extended piping, valves, sleeves, associated with this work.
· Jacobs will identify on the plan set and provide a quantity for the manhole
adjustments, water valve adjustments, etc.

included on this project. Jacobs will add hydromuleh callout/limits on the plans.
· Jacobs will increase the radii for the driveways at the plant nursery on the west end of
the project to accommodate larger sized trucks.
· The City will coordinate with the Parks Department as to the required brick pavers,
stamped concrete or crushed rock that is to be called out in the median noses. Jacobs
will revise the call outs as necessary on the paving plan sheets.
· Jacobs will reverify, to the best of the information currently available, the elevations
at new storm drain & water line crossings, as well as other new underground utility
crossings.
· Jacobs will add the following note at the "DWU manholes" located at approximately
sra. 44+00: "After staking of roadway and prior to construction, please contact Erling
Holey at 214-671-9524 with DWU. The location of the manholes with respect to the
proposed roadway needs to be verified".
· Jacobs will revise 'as' to 'at' on sheet 5A, phase I, item 11.
· Jacobs will revise 'should' to 'shall' on sheet 5A, general notes, note 11.
· The City will provide to Jacobs the plans for three new streets or entrances. They are
Starleaf St, St Joseph's entrance and Riverview Office Development entrance. Jacobs
will address the traffic control access of these streets/entrances in the phasing plans as

the plan set.
· At sta. 65+00, Jacobs will callout a meter relocation if necessary and callout a new
tie-in for the water line to the "agriculture building" on the north side of Sandy Lake
to the existing 12" water line on the south side of the road.
· Jacobs will callout and show four new 8" water line stubouts with new fire hydrants
on the north side of the road, from the existing 12" water line on the south side.
There will be three taps to the Peter Park property - at Riverview, at Riverchase and
at the east end of the parcel. There will be one stub out to the Holmes property.
Jacobs will show the piping, valves, sleeves, associated with this work.
· Jacobs will provide The City a set of plans at 90% complete for their review. The
City will provide comprehensive comments at that point. Jacobs will then
