Dear Mr. Zohne:
JAN 2, 6 2008
January 237 2008
Gorrondona and Associates, Inc. (GA), is pleased to submit a cost proposal for Subsurface Utility
Engineering (SUE) required for the above referenced project. This proposal is based on information
depicted on the maps that you provided and our phone conversation.
Introduction
GA will perform the SUE work required for this project in general accordance with the recommended
practices and procedures described in ASCE Publication CUASCE 38-02 (Standard Guideline for the
Collection and Depiction of Existing Subsurface Utility Data). As described in the mentioned ASCE
publication, four levels have been established to describe the quality of utility location and attribute
information used on plans. The four quality levels are as follows:
• Quality Level D (QL"D") —Information derived from existing records;
• Quality Level C (QL"C") to, QL"D" information supplemented with information obtained by
surveying visible above -ground utility features such as valves, hydrants, meters, manhole
covers, etc.
• Quality Level B (QL"B") — Two-dimensional (x,y) information obtained through the
application and interpretation of non-destructive surface geophysical methods. Also known as
"designating" this quality level provides the approximate horizontal position of subsurface
utilities within approximately one foot.
• Quality Level A (QL"A") — Also known as "locating", this quality level provides precise three
dimensional (x,y,z) information at critical locations by exposing specific utilities. Non-
destructive vacuum excavation equipment is used to expose the utilities at specific points
which are then tied down by survey.
It is the responsibility of the SUE provider to perform due -diligence with regard to records research
(QL "D") and acquisition of available utility records. The due -diligence provided for this project will
consist of reviewing the "As -Built" documents previously compiled by others. Utilities that are not
identified through these efforts will be here forth referred to as "unknown" utilities. GA personnel
will scan the defined work area using electronic prospecting equipment to search for "unknown"
utilities. However, GA is not responsible for designating and locating these "unknown" utilities.

Scope of Work
Based on information provided by TCB, Inc., GA has developed a preliminary scope for the SUE
work required for this project. The scope of work may be modified, with prior approval, during the
performance of the SUE fieldwork if warranted by actual field findings.
The scope of this proposal includes Quality Levels "A" and "B" along several drainage projects
discussed in detail below.
o Wilbarger-Hughes: A proposed 30-inch storm drain is proposed to be installed in
Wilbarger Street from Hillside Avenue to South Hughes Avenue with a length of
approximately 220-feet. Additionally, two inlets will be installed; a 10-foot and 20-foot
extending into Hughes Avenue and Wilbarger Street respectively. Since the alignment of the
proposed 304nch storm is inside the curb line of Wilbarger Street we propose to use $2.50 per
foot of proposed storm to designate utilities inside the curbs which includes the two inlet
locations.
o Ederville: A 30-inch storm drain is proposed from the existing 72-inch line in Eastchase
Parkway running east approximately 820-feet towards Meadowbrook Lane. In addition 4-
inlets are proposed, two on each side of the street. Since the alignment of the proposed 30-
inch storm is inside the curb line of Ederville we propose to use $2.50 per foot of proposed
storm to designate utilities inside the curbs which includes the four new inlet locations.
A 244nch storm drain is proposed just west of the Ederville and Meadowbrook Drive
intersection along with ditches on each side Ederville running 300-feet west for the
intersection of Ederville and Meadowbrook Drive. Since ditches are proposed on both sides of
Ederville we propose to use $2.00 per foot of proposed ditch to designate utilities which
includes the 244nch storm drain crossing.
o Meadowbrook East: A 30-inch and 244nch storm pipes are proposed to cross
Meadowbrook as well as 1,000 feet of proposed drainage ditch. The drainage ditch is
proposed only on the west side of Meadowbrook we propose to use $2.00 per foot of proposed
ditch to designate utilities which includes the 24 and 304nch storm drain crossings.
o Meadowbrook South: A 274nch storm pipe is proposed to cross Meadowbrook as well as
750 feet of proposed drainage ditch. The drainage ditch is proposed only on the north side of
Meadowbrook we propose to use $2.00 per foot of proposed ditch to designate utilities which
includes the 27-inch storm drain crossing.
All surveying that is required for collection of SUE field data will be performed by Gorrondona &
Associates. Upon receipt of the processed survey data, we will perform a preliminary review of the
data to check for completeness and accuracy. Once this preliminary review is complete we will
prepare a utility.
Designating Procedures
Prior to beginning field designating activities, GA's field manager will review the project scope of
work and available utility records. Once these initial reviews are complete, the field manager and
technicians will begin designating the approximate horizontal position of known subsurface utilities
within the specified project limits. A suite of geophysical equipment (electromagnetic induction,
magnetic) will be used to designate metallic/conductive utilities (e.g. steel pipe, electrical cable,
PAPr[jects\I'C&B\Utilities\CFPW - 00482\propDmI.doc
N1;. R ck Zi)hile.
YU3 1
telephone cable). Non-metallic/non-conductive utilities will be designated using other proven
methods, such as rodding and probing. Where access is available, a sonde will be inserted into the
utility line (e.g. PVC gravity sewer pipe) to provide a medium for signal transmission, which can then
he designated using geophysical equipment.
Accurate collection and recording of designated utilities is a critical component of the SUE process.
GA has developed a proven method of collecting and recording survey information once the utilities
have been designated in the field. GA's field manager will produce detailed sketches depicting each
utility as well as relevant surface features such as roadways, buildings, manholes, fire hydrants, utility
pedestals, valves, meters, etc. Each utility will be labeled with a unique ID code. For example, if two
buried electric cables exist on the project, one will be labeled E1 and the other E2. Paint and pin flags
will be used to designate the utilities in the field. A labeled pin flag or paint mark will be used to mark
each location where a survey shot is required. Shot points will typically be placed at W040ot
intervals on utilities running parallel to the alignment and at 50400t intervals on utility crossings. The
locations will be numbered sequentially for each individual utility line. For example, if there are 50
shots required on buried electric line El, the points will be numbered E1-1 through E1-50.
Preliminary field sketches depicting the designated utilities will be prepared for use during subsequent
surveying activities. These sketches will also be used to check the survey information for
completeness and accuracy.
Locating Procedures
GA will utilize its utility designating marks to layout the test -hole locations. When test holes are
required under pavement, GA will use a 10" core drill to prevent spatting. The test hole will be
backfilled with clean, dry backfill and finished with like material, concrete or asphalt.
GA will utilize non-destructive vacuum excavation equipment to excavate test holes at the required
locations. Once each utility is located, GA will record the utility type, size, material, depth to top, and
general direction. Each test hole will be assigned a unique ID number and will be marked with
rebar/cap, nail/disk, or chiseled X, as appropriate. The test -hole ID number and other pertinent utility
information will be placed at each test -hole location. Test -hole excavations will be backfilled with
appropriate material and the original surface will be restored. The backfill will be compacted in lifts
by mechanical means to prevent future settlement.
Test -hole locations will be added to the previously mentioned field sketches for use during surveying
activities.
Deliverables
GA will produce an electronic SUE file depicting the type and horizontal location of the designated
utilities. The size of each utility will also be presented in the SUE file where test -holes have been
completed. Where no test -holes have been completed, the size and material type will be provided only
if the information is indicated on available record drawings. TCB will provide Gorrondona &
Associates with base map/topographic files in Microstation V8 or ACAD format for use in preparing
the SUE deliverable.
GA will produce a summary sheet containing test hole field notes. The SUE file depicting designated
utility information will inc°tui� test hole locations.

Estimated Fees
The cost to perform the Quality Level `B" SUE work is as follows.
Wilbarger-Hughes - $550.00 (220 LF Street x $2.50/LF)
Ederville - $3,250.00 (820 LF of Street x $2.50/lf + 600 LF of Ditch x $2.00/LF)
Meadowbrook East - $27000.00 (1,000 LF of Ditch x $2.00/LF)
Meadowbrook South - $1,500.00 (750 LF of Ditch x $2.00/LF)
This proposal is based on the assumption that a total of 1 Z test holes will be excavated to collect any
vertical utility data that may be required. We have assumed that 8 holes will be in the 0,00 to 4.00
foot depth range and that 4 holes will be in the 4.01 to 8.00 foot depth range. The cost for test•holes is
as follows:
Depth Cost
0.00 to
4.00 ft.
$800.00
4.01 to
8.00 ft.
$15000.00
8.01 to
12.00 ft.
$11300.00
12,01 to
15.00 ft.
$1,550.00
Over 15.01 ft
$2,000.00
Based on the anticipated utilities the cost for designating (QL"B"} is $7,300.00 and the cost for
locating kxmz$107400.00. The total cost for SUE and applicable survey is seventeen thousand,
four hundred dollars and 00/100 cents ($17,700.00). This price is contingent upon receiving notice -
to -proceed for all streets simultaneously.
We look forward to working with you on this very important project. If you have any questions or
require additional information, please contact me.
