Content: An Ayres Associates inspection team has recently inspected the above referenced bridge
and observed the following deficiencies noted below.
Summary: During the June 27, 2023 Interim Inspection, the inspectors observed the following:
The cold joint between the apron and floor slab (horizontal joint) at the east end of the culvert has
signs of soil loss in front of Cells 1, 2 and 3 and the seam could be probed intermittently along the
joint in front of all three cells with up to 15 feet of penetration. The approximate size of undermined
area is 40 ft. long (full length of the east toe) x up to 3ft. high x up to 15ft. back under and
encroaches into the northbound travel lane. Due to limited access, the full extent of the
undermining could not be determined. At present, there are no signs of settlement of the culvert or
roadway above and no signs of significant structural deficiencies such as cracking or spalling of the
concrete. Refer to Photos 1, 2 and attached Sketch 1. REPAIR
The cold joint between the apron and floor slab beneath the northeast wingwall has a void 24in. x
4in. x 18in. back under. REPAIR
East toe wall (apron) is exposed up to 9in. along the length with maximum exposure occurring in
front of Cell 3. Rubble is along the east toe wall. Refer to Photo 3. REPAIR
Recommendations: Investigate the full extent of undermining and repair.

Mr. Eliason:
Tierra, Inc. (Tierra) has performed geotechnical engineering services for the above referenced
project. This report presents the findings of our field exploration and geotechnical engineering
recommendations.
Project Information
Based on information provided to us, we understand that the City of Winter Springs recently
received an inspection letter titled “Significant Deficiency Advisory - Toe Slab Undermining,
Interim Bridge Inspection - June 27, 2023, Bridge No. 775704 - Murphy Road over Gee Creek”
prepared by Ayres as part of the FDOT District 5 Local Government Bridge Inspection program.
The inspection indicated that the east end of the culvert had significant soil loss and undermining
of the toe slab and recommended further investigation and repair. The approximate limits of the
undermining as provided in the letter are depicted below.

Review of Existing Plans
The original plans titled “Construction Plans, Paving and Drainage, North Orlando Terrace Box
Culverts, Village of North Orlando, Florida”, dated January 1973 prepared by Kuhrt and
Associates, Inc. were provided to us prior to the start of our study. The plans indicate the culvert
is 36 feet in length with three 4 ft. x 12 ft. reinforced concrete chambers with 8 inch thick walls
separating each chamber. The toe slab at the entry and exit points of the culvert is indicated to
be 8 inches thick and extend 2 feet below the bottom slab of the culvert. The original construction
plans are included in the attachments as a reference.
Soil Borings
To evaluate the subsurface conditions adjacent to the existing culvert, Tierra performed two (2)
Standard Penetration Test (SPT) borings to depths of approximately 25 feet below existing grade.
The boring locations were located in the field by Tierra and recorded using hand-held GPS units
with a reported accuracy of + 10 feet. The approximate boring locations are presented on the
Boring Location Plan in the Appendix.
In general, the subsurface conditions consisted of alternating deposits of sands with variable silt
content (SP, SP-SM and SM materials) from the ground surface to the termination depths of the
borings (25 ft.). The SPT N-values indicate the sands to be in a very loose to loose condition in
the upper approximate 16 feet followed by medium dense conditions to the termination depths of
the borings.
Groundwater Conditions
At the time of our field investigation (August 11th, 2023), the groundwater table was encountered
at a depth of 4 to 5 feet below existing site grades and generally matched or was slightly above
the water levels observed in the canal.
Engineering Evaluations and Recommendations
Based on the results of our subsurface explorations and the findings presented in the Inspection
Report dated June 27, 2023, the noted soil loss is most likely the result of high flow events within
the creek that undermined and washed out soils from beneath the toe slab on the downstream
exit of the culvert. In order to remediate the noted deficiencies, Tierra recommends a program of
polyurethane injection be completed in combination with the installation of rubble riprap or gabion
mattresses within the creek on the east side (downstream exit) of the culvert.
The intent of the polyurethane injection program is to fill any voids below the toe slab, stabilize
the subsurface soils, seal potential raveling avenues, and improve overall foundation support.
The installation of rubble riprap materials or gabion mattresses will help to reduce the exit
velocities of concentrated flows during high flow events and reduce the potential for any future
scour or undermining.

Polyurethane Injection Program
Polyurethane injection should be performed in accordance with FDOT Specification Section 173
“SHALLOW SUBSURFACE POLYURETHANE INJECTION”. A copy of Specification Section 173
along with a recommended Polyurethane Injection Point Location Plan are attached. Based
on the attached plan, a total of 84 injection points are anticipated. The polyurethane injection
points should extend to a minimum depth of 5 foot below the base of the culvert (this depth could
potentially be reduced to 3 feet on the upstream half of the culvert if no undermining is
noted/observed during installation of the injection points). It is expected that the polyurethane
injection will occur in three phases while the flow of the creek is diverted to the adjacent culvert cells.
We anticipate that 8 to 12 gallons of single component (65 to 100 lbs. of two-component)
polyurethane will be required at each injection point to fill voids, densify the soils, seal potential
raveling avenues, and improve overall foundation support of the existing culvert structure.
Rubble Riprap (Bank and Shore Protection)
The rubble riprap materials (bank and shore protection), if utilized, are recommended to be placed
beginning at the edge of the culvert on the downstream exit for a minimum distance of
approximately 30 feet to the east. The material used for this application should meet the
requirements of Section 530-2.1.3.1 Rubble (Bank and Shore Protection) of the FDOT
Specifications for Road and Bridge Construction (2023).
Gabion Mattress
Gabion mattresses, if utilized, should be installed beginning at the edge of the culvert on the
downstream exit for a minimum distance of approximately 30 feet to the east. Gabion mattresses
are recommended to be a minimum of one foot thick and constructed using rock and wire mesh
baskets in accordance with Section 530 of the FDOT Specifications for Road and Bridge
Construction (2023).
Report Limitations
Our services have been performed, our findings obtained and our recommendations prepared in
accordance with generally accepted geotechnical engineering principles and practices at the time
of this report. Tierra is not responsible for the conclusions, opinions or recommendations made
by others based on this data.
The scope of the exploration was intended to evaluate soil conditions within the limits of the noted
culvert. The analyses and recommendations submitted in this report are based upon the data
obtained from the Inspection Report and the results of our field investigations. If any subsoil
variations become evident during the course of this project, a re-evaluation of the
recommendations contained in this report will be necessary after we have had an opportunity to
observe the characteristics of the condition encountered.

heaters, hoses, containers, valves and gauges to efficiently conduct and control the work. Do Not Use Without CO Specs Authorization29
173-5 Construction Requirements.
173-5.1 Pre-Construction Submittals: Upon approval of the Contractor’s qualifications,
submit the following information to the Engineer for review and approval prior to performing
any work:
1. The proposed start date and duration of the project sequence.
2. The type and size of all equipment to be used. Describe the methods to be used
to achieve the requirements of this Specification.
3. The materials to be used and anticipated injection rate.
4. A description of construction methods to be used for site preparation, including
the methods for measurement concerning slab lifting requirements, clearing of debris and a pre-
construction survey documenting existing cracks/damage to concrete curb and gutters or adjacent
structures.
5. A description of construction methods to be used to perform the injection of the
polyurethane with a detailed sequence of injection operations.
6. Manufacturer’s technical data sheet verifying that the polyurethane materials
meet all requirements this Specification, including the densities (in pounds per gallon) of each
individual component (resin and activator) of any two part polyurethane materials.
7. Certification for the metering device or the Contractor’s plan for measuring the
material.
8. Proposed plan to monitor inside subsurface drainage structures during injection
and to prevent excessive polyurethane migration into any existing drainage structures.
173-5.2 Pavement Profile: Prepare a pavement and structure profile from laser level
measurements of each area to document pre-existing conditions to ensure movement does not
exceed 1/16 inch of the final planned elevation during the injection operations. Prior to
beginning any work, submit a report documenting this inspection and the recorded elevations to
the Engineer for approval. Include photographs of the area documenting the location and length
of existing cracks. Prior approval of this report will not be required for emergency response
work.
173-5.3 Quality Control: For polyurethane solutions which require mixing or blending
of multiple components, perform a daily quality check in the presence of the Engineer, using the
flow meters and/or measurement devices, on the ratio of the parts provided by the injection
system. Perform a test shot of material from one component source at a time with a minimum of
5 gallons of each material, comparing the output in gallons of resin to the gallons of activator, if
applicable (resin material only for one component foam system). Determine the injection ratio
for two component systems. If this ratio differs from the approved solution ratio used at the test
point locations, check the system for problems, make any necessary adjustments until a proper
ratio is achieved. Following these checks and adjustments, and prior to performing the work each
day, reset the measurement devices on the pumping units to zero.
The Engineer reserves the right to perform compressive strength testing on polyurethane
samples.
173-5.4 Testing.
173-5.4.1 Pre-Production: When pre-production test injection points are shown
in the Plans, complete a pre-production polyurethane injection performance testing program.
Prior to the injection at production point locations indicated in the Plans, determine the rate and
amount to be injected to obtain the required improvement. Assess the cure rate for the proposed
process by the initial completion of pre-production polyurethane injection performance testing at Do Not Use Without CO Specs Authorization30
pre-production test injection points shown in the Plans. Inject at the pre-production test point
locations using the proposed materials, injection rates, and processes anticipated for production.
To verify adequate subsurface improvement has been achieved, perform a
minimum of two standard penetration test (SPT) soil borings in accordance with ASTM D1586,
using safety or automatic hammer) or dynamic cone penetrometer (DCP) soundings in
accordance with ASTM D6951, at locations approved by the Engineer. After injection of the test
points, locate at least one SPT boring or DCP sounding just outside the injected area and at least
one SPT boring or DCP sounding centrally within the test point grid, unless shown otherwise in
the Plans. Use the same equipment for all tests. Submit the results of the SPT borings and DCP
soundings, the recommended injection rate and injection cut-off criteria to the Engineer for
review and approval prior to proceeding with the production point locations. The Engineer may
require additional SPT borings or DCP soundings.
Do not adjust the polyurethane components, ratios or injection processes during
production point injection without the approval of the Engineer.
173-5.4.2 Post-Production: Additional subsurface testing, performed using SPT
soil borings or DCP soundings, may be required as directed by the Engineer on each project lane
to confirm existing subgrade soil conditions based upon available subsurface information. The
Engineer may require access holes to be drilled to allow the insertion of video equipment to
assess the size of existing voids.
173-5.5 Injection Placement: Inject the polyurethane to the depth shown in the Plans. If
not shown in the Plans, select the exact location, spacing, hole size and depth of the injection
tubes with the approval of the Engineer. All one component polyurethane material must be
injected at least one foot below the existing water table. When direct access to voids is available,
provide a means to confine the placement and inject the polyurethane directly into the void.
When direct access to voids is not available, drill a series of holes sized no larger than required
for the injection tube placement, at approximately 3 to 4 foot intervals or as determined by the
Engineer When drilling through reinforced concrete, determine the location of existing
reinforcing prior to drilling injection holes. Do not drill into or cut existing reinforcing. If
existing reinforcing is encountered during drilling, shift the hole to clear reinforcing.
Install and operate a level control system during the injection operation. Monitor
the elevation of the pavement or structure profile to detect any movement within a 10 to 15 foot
radius from the point of injection during injection operations, or as directed by the Engineer.
Continuously monitor laser level or dial indicator micrometer readings during injection
operations to determine sufficient material usage as indicated by pavement movement of
1/16 inch or less. Additionally, monitor all directly adjoining structures, such as adjacent bridge
spans, road surfaces, curb and gutter to detect and prevent unintended movement.
Inject the material gradually to avoid excessive force build up. If the movements
exceed 1/16 inch beyond the desired profile, take corrective actions to stop the movement and
perform repairs. Immediately notify the Engineer if signs of damage are observed, such as new
cracks in the pavement, increased size of existing cracks, or separation of joints in paved and
unpaved surfaces. Repair any damage to the concrete slab/pavement, adjacent structures, gutters,
and shoulders resulting from the injection operations to the satisfaction of the Engineer, and at no
cost to the Department.
Remove any excess polyurethane material extruding from cracks or the drilled
holes. Seal the drilled holes to the full depth of the slab section with cement grout. Do Not Use Without CO Specs Authorization31
Allow the polyurethane material to cure before allowing traffic on to approach
slabs adjusted by polyurethane injection.
173-5.6 Faulted Joints. For undersealing and leveling of faulted joints of concrete
pavement, inject to fill any void in the sub-base. When the void is filled and the area is
stabilized, begin lifting and realigning panels to proper grade for ride improvement.
173-5.7 Drainable Bases: Ensure the material does not enter the drainable base. For
stabilization of pavement with a drainable base, place injection tubes approximately 24 inches
below the bottom of the drainable base. Inject the material to stabilize the subgrade and then
move the subbase and base material up, compressing it against the bottom of the pavement,
returning the pavement to near its original grade.
173-5.8 Lifting: In some situations for lifting, the subgrade will need to be stabilized.
When stabilization is required, an injection depth will be determined by the Contractor and
approved by the Engineer, but will not be at a depth greater than 3 feet below the pavement base.
Inject the material until the dip in the pavement is removed and the pavement or structure is
brought to the desired grade.
If stabilization is not necessary, the injection depth will be 12 or more inches
below the pavement base to fill the void and lift the pavement or structure to the desired grade.
173-5.9 Sleeper Slabs: For bridge approach slabs that have sleeper support slabs, drill all
holes, fully sleeved by tubes, into the base soils to prevent any injection of polyurethane between
the sleeper slab and the pavement. Insert injection tubes to a minimum depth of 4 to 5 feet and a
minimum depth of 1 to 2 feet below the bottom of the sleeper slab. Inject the material through
each tube until the soils are stabilized as evident when movement of the pavement is detected.
Continue to inject material beneath the sleeper slab to lift the sleeper slab and pavement together
to the desired grade.
173-5.10 Edgedrains: If edgedrains are present, keep all injections within 4 feet of the
edgedrain and at least 18 inches below the bottom of the edgedrain.
173-5.11 Punch Outs: Prior to replacement of short sections of concrete or asphalt
(punch-outs) where base and subbase are suspected as contributing to the pavement failure,
perform injections to stabilize the base and subbase to avoid cutout and removal of base and
subbase. Ensure removal of the existing pavement does not disturb the tubes or the newly
stabilized base and subbase. After removal of the pavement, cut the tubes off at the top of the
base material.
173-5.12 Blowouts: Take responsibility for any pavement blowouts, excessive pavement
lifting, pavement damage or exacerbation of misalignment that may occur as a result of the work.
If movement exceeds 1/16 inch beyond the desired movement, take corrective actions to stop the
movement. Repair the area to the satisfaction of the Engineer and at no cost to the Department.
173-5.13 Storm Drains: For lifting, sealing and filling of voids around storm drains
including pipe, manholes and other built structures, submit a plan of action to the Engineer for
approval. Prior to performing work, evaluate the integrity of the pipe and storm drain system
through inspection, either visual or by remote camera, to determine the correct placement of
polyurethane. Perform post installation evaluation of the work by similar means. Ensure that any
injected material entering the storm drain system during the installation work is removed and
disposed of accordingly.
173-5.14 Water Control Structures: For void filling and sealing of water control
structures, culverts and sea walls, submit a plan of action to the Engineer for approval. Base the Do Not Use Without CO Specs Authorization32
plan of action on the specific situation and propose the injection spacing, elevations, quantities
and desired result.
173-6 Report.
Submit a report to the Engineer documenting the polyurethane material injection and
instrumentation. Provide before and after photos of the project, a diagram of injection ports,
injection volumes per port, problems encountered during construction, resolutions made, and
certification testing results in the report. Include pavement profiles before and after injection,
document whether the transition at joints are smooth, and whether there are additional cracks in
the pavement. Submit the report prior to final acceptance of the project. In addition, supply as-
built injection drawings and grade readings within 5 days of completing the project.

WHEREAS, the Principal has executed a contract with the OWNER, dated ______________, for
the construction of the ___________________________________ project in the City of Winter
Springs, Seminole County, Florida (the “Project”); and
WHEREAS, the OWNER has required the Principal to furnish a performance bond in accordance
with law and as a condition of executing the Contract with Principal; and
WHEREAS, this bond is being entered into to satisfy the requirements of Section 255.05(1),
Florida Statutes and the Contract referenced above, as the same may be amended, and additionally,
to provide common law rights more expansive than as required by statute.
NOW THEREFORE, the Surety and the Principal, both joint and severally, and for themselves,
their heirs, administrators, executors, successors and assigns agree as follows:
1. CONTRACT INCORPORATED; SURETY AND PRINCIPAL BOUND FOR FULL
PERFORMANCE. The Contract is incorporated by reference and made a part of this bond.
The Surety and the Principal are bound for the full performance of the Contract including
without exception all of the Contract Documents (as defined in the Contract) and all of their
terms and conditions, both express and implied. Without limiting the Principal’s and Surety’s
obligations under the Contract and this bond, the Principal and Surety agree:
A. Promptly and faithfully perform their duties and all the covenants, terms, conditions, and
obligations under the Contract including, but not limited to the insurance provisions,
guaranty period and the warranty provisions, in the time and manner prescribed in the
Agreement, and
B. Pay OWNER all losses, damages, delay damages (liquidated or actual), expenses, costs
and attorneys’ fees under section 627.756, Florida Statutes, including costs and attorney’s
fees on appeal that OWNER sustains resulting directly or indirectly from any breach or
default by Principal under the Contract, and
45
C. Satisfy all claims and demands incurred under the Contract, and fully indemnify and hold
harmless the OWNER from all costs and damages which it may suffer by reason or failure
to do so.
2. OWNER’S AFFIDAVIT OF CONTRACTOR BREACH OR DEFAULT. If the OWNER
shall provide to Surety the written affidavit of the OWNER stating that the Principal is in
breach or default of the Contract, and that such breach or default remains uncured by the
Principal, then upon delivery of such affidavit to the Surety in the method for providing notices
as set forth in Paragraph 7 below, Surety must promptly notify the OWNER in writing which
action it will take as permitted in Paragraph 3.
3. SURETY’S OBLIGATION UPON DELIVERY OF OWNER’S AFFIDAVIT OF
CONTRACTOR’S BREACH OR DEFAULT. Upon the delivery of the OWNER’s
affidavit of breach or default by the Principal as provided in Paragraph 2 above, the Surety
may promptly remedy the breach or default or must, within ten (10) days, proceed to take one
of the following courses of action:
A. Proceed Itself. Complete performance of the Contract including correction of defective
and nonconforming Work through its own CONTRACTORs or employees, approved as
being acceptable to the OWNER, in the OWNER’s sole discretion, provided, however, that
OWNER’s discretion in approving the Surety’s CONTRACTOR will not be unreasonably
withheld as to any CONTRACTOR who would have qualified to offer a proposal on the
Contract and is not affiliated in any way with the Principal. During this performance by
the Surety, the OWNER will pay the Surety from its own funds only those sums as would
have been due and payable to the Principal under the Contract as and when they would
have been due and payable to the Principal in the absence of the breach or default not to
exceed the amount of the remaining Contract balance less any sums due the OWNER under
the Contract. During this performance by Surety, any payment bond required under the
Contract must remain in full force and effect; or
B. Tender a completing CONTRACTOR acceptable to OWNER. Tender a
CONTRACTOR, together with a contact for fulfillment and completion of the Contract
executed by the completing CONTRACTOR, to the OWNER for the OWNER’s execution.
OWNER’s discretion to approve Surety’s completing CONTRACTOR will not be
unreasonably withheld as to any CONTRACTOR who would have qualified to offer a
proposal on the contract and is not affiliated with the Principal. OWNER’s discretion to
approve CONTRACTOR as the completing CONTRACTOR and to approve the tendered
contract shall be in OWNER’s sole and absolute discretion. Upon execution by the
OWNER of the contract for fulfillment and completion of the Contract, the completing
CONTRACTOR must furnish to the OWNER a performance bond and a separate payment
bond, each in the form of those bonds previously furnished to the OWNER for the Project
by the Principal. Each such bond must be in the Penal Sum of the full cost to complete the
Contract. The OWNER will pay the completing CONTRACTOR from its own funds only
those sums as would have been due and payable to the Principal under the Contract as and
when they would have been due and payable to the Principal in the absence of the breach
or default not to exceed the amount of the remaining Contract balance less any sums due
46
the OWNER under the Contract. To the extent that the OWNER is obligated to pay the
completing CONTRACTOR sums which would not have been due and payable to
CONTRACTOR under the Contract (any sums in excess of the then remaining Contract
balance less any sums due the OWNER under the Contract), the Surety must pay the
OWNER the full amount of those sums at the time the completing CONTRACTOR tenders
an invoice to the OWNER so that the OWNER can utilize those sums in making timely
payment to the completing CONTRACTOR; or
C. Tender the Full Penal Sum. Tender to the OWNER the full Penal Sum of the performance
bond. The OWNER will refund to the Surety without interest any unused portion not spent
by the OWNER procuring and paying a completing CONTRACTOR or completing the
Contract itself, plus the cost allowed under Section 4, after completion of the contract for
fulfillment and completion of the Contract and the expiration of any applicable warranties;
or
D. Other Acts. Take any other acts mutually agreed upon in writing by the OWNER and the
Surety.
E. IT SHALL BE NO DEFENSE TO SURETY’S OBLIGATION TO UNDERTAKE
ONE OF THE PRECEDING COURSES OF ACTION THAT THE PRINCIPAL
CONTENDS THAT IT IS NOT IN BREACH OR DEFAULT OF THE CONTRACT,
OR THAT THE NOTICE OF BREACH OR DEFAULT WAS DEFECTIVE, OR
THAT THE PRINCIPAL HAS RAISED ANY OTHER CLAIM OF DEFENSE OR
OFFSET, PROVIDED ONLY THAT THE SURETY HAS RECEIVED THE
AFFIDAVIT OF THE OWNER AS SPECIFIED IN PARAGRAPH 2.
4. SURETY’S ADDITIONAL OBLIGATIONS. In addition to those duties set forth herein
above, the Surety must promptly pay the OWNER (i) all losses, costs and expenses resulting
from the Principal’s breach(es) or default(s), including, without limitation, fees (including
attorney’s fees pursuant to section 627.756, Florida Statutes and related costs), expenses and
costs for architects, ENGINEERs, consultants, testing, surveying and attorneys, plus (ii)
liquidated or actual damages, whichever may be provided for in the Contract, for lost use of
the Project, plus (iii) re-procurement costs and fees and expenses, plus (iv) costs incurred at
the direction, request, or as a result of the acts or omissions of the Surety; provided that in no
event shall Surety’s liability exceed the Penal Sum of this Bond.

Contract, including changes in the Contract Time, the Contract Sum, the amount of liquidated
damages, or the work to be performed under the Contract.
