SECTION 1
INTRODUCTION
This report presents the results of our geotechnical evaluations and recommendations for
proposed bridges associated with improvements to I-264 in the City of Virginia Beach,
Virginia. These bridges will form parts of a new Collector-Distributor (CD) Road along
the south (eastbound) side of I-264, a widening of I-264, a new flyover crossing the
interstate, and a low-profile “wharf” structure where the flyover road will connect to
existing Greenwich Road. A general description of the subsurface conditions and
geotechnical recommendations for the design of the foundations for these structures are
included in this report.
The borings and laboratory testing considered in our evaluations were completed by HDR
Engineering, Inc. under their contract with VDOT. In addition to completing a
comprehensive boring program, HDR’s scope included evaluation of the subsurface
conditions with respect to embankments and roadway construction, with emphasis on
settlement and global stability. The scope included in the current design effort is limited
to the proposed structures, such as bridges, retaining walls, and larger drainage
conveyances. HDR completed Geotechnical Engineering Reports (GERs) for the
interchange improvement program, divided into seven Project Study Areas (PSAs). Of
those, the following four, all dated September 20, 2013, are pertinent to this contract:
GER No. 1: Greenwich Road Overpass
GER No. 4: I-264 CD
GER No. 5: Newtown
GER No. 6: Witchduck

This report is intended to support the bridge design, and provide the design team and
VDOT with information regarding the approach to the foundation selection and detailing
for the four bridges. The site location map, extracted from GER No. 4, is depicted in
Appendix A1.
Also, separate geotechnical reports were submitted which address the associated retaining
walls and culverts.
PROPOSED CONSTRUCTION
The site lies near the western limits of the City of Virginia Beach; however, the recently-
designed associated contract immediately west of this section lies in the City of Norfolk.
This project, located in the southeast quadrant of the I-64/I-264 interchange, includes
three new bridges and one bridge widening, as listed in the following table:

The proposed bridges and associated roadway improvements are intended to improve
traffic flow, increase capacity, and enhance safety for the traveling public. The existing
elevations throughout the site, primarily the result of earlier highway projects, will
generally provide sufficient grade separation for clearance under the bridges without the
need for extensive grading; however, widening and/or approach fills will be needed at
some of the abutments. The exception is the new flyover bridge, where significant fill
embankments are proposed.
The anticipated design is for the bridge abutments and piers to be mostly supported by
pile-supported foundations; however, there are several locations where pier columns will
be directly supported by drilled shaft foundations, including the flyover pier in the
median of I-264, and the piers of the widened bridge over the former Norfolk Southern
Railway ROW. Anticipated factored loads are discussed later in this report.
SITE CONDITIONS
As the area is fully developed and most of the planned improvements are upgrades to the
existing infrastructure, the site generally consists of the rights of way for the existing
highways and local roads. The notable exception is the flyover bridge, which will cross
the corners of two existing ponds as well as an adjacent woods. These ponds are
believed to be the result of borrow pits excavated during the original highway
construction; they are not a part of the local water or storm water infrastructure.
Surface features include the existing I-264 highway and ramps, and the bridges over
Newtown Road and the former right-of-way of the Norfolk Southern Railroad. The
proposed construction generally runs parallel and south of the existing highway, with the
exception of the flyover, which crosses I-264 and parallels the north side in an easterly
direction, connecting to the existing western terminus of Cleveland Street. Approximate

existing ground elevations range from 8, to 40, with the higher elevations the result of fill
placed for the existing approaches and abutments.
SITE GEOLOGY
The following paragraphs comprise a brief overview of the geologic setting at the site.
Detailed discussions of the local geology are provided in the previously referenced
Geotechnical Engineering Reports prepared by HDR.
The site lies in the Coastal Plain which encompasses the eastern portion of the state,
beginning at the “Fall Line,” roughly approximated by Interstate I-95, where, moving in a
westward direction, the coastal sediments transition to bedrock-derived Piedmont
materials.
The geologic information covering the Virginia Coastal Plain indicates that the site is
underlain by the geologically recent Tabb Formation, and the more ancient Yorktown
Formation, a subunit of the Chesapeake Group, at greater depths.
The Quaternary age Tabb Formation is present throughout the upper portion of the
subsurface profile. Earlier publications referred to this formation or its subunits, as the
Norfolk, Sand Bridge, and Kempsville formations. The Norfolk Formation primarily
consists of soft to medium stiff clays, typically exhibiting high plasticity. The Sand
Bridge and Kempsville Formations generally consist of silty and clayey sands, which are
very loose to loose nearer the surface, transitioning to medium dense nearer the base.
Occurring alternately with the sands are very soft to medium stiff clays, generally
exhibiting high plasticity.
Below these geologically recent strata lies the Tertiary age Yorktown Formation, a
subunit of the Chesapeake Group, which consists of gray silty sand interbedded with
sandy silt. The Yorktown contains marine shell fragments, which are typical with most
Chesapeake Group formations. These strata are preconsolidated, and as a result are
medium dense to dense in situ.

It must also be anticipated that very recent Holocene age Alluvium is present, particularly
along the present and the former banks of local streams. Note that many of the stream
channels were likely relocated during earlier construction projects, so alluvium could be
present in former stream channels, in addition to the ones presently observable. Alluvial
materials of this type consist of gravel, sand, silt, and clay of highly variable composition
and sorting. Artificial fill placed to form the highway embankments is also present along
the right of way. Considering the age of the roadway, the old fill strata should be
expected to be highly variable, and may not meet current standards for compacted
highway embankment fill.
SUBSURFACE EXPLORATION
As discussed above, VDOT engaged HDR Engineering, Inc. (HDR) to perform
subsurface explorations, laboratory soil testing, and prepare geotechnical reports. HDR’s
scope was to use the subsurface and laboratory data to complete engineering analyses
addressing roadways and embankments; specifically design considerations such as global
stability and settlement. Their reports were also to present and transmit the data for use
in the present design effort for major structures such as bridges, retaining walls and large
culverts. Since these voluminous documents have already been submitted and accepted
by VDOT, they are not reproduced herein; however, they should be considered
incorporated into this report by reference.
Standard Penetration Test (SPT) Borings
The explorations considered for the bridges were generally limited to those drilled to
the Yorktown bearing stratum, which begins in the vicinity of elevation -80 to -100.
These subject borings were drilled to elevations ranging from -100 to about -130.

Bridges B601, B602, B603 and B621 Virginia Beach, Virginia

Cone Penetrometer Test (CPT) Probes
A series of (Cone Penetrometer Test) CPT probes were performed to supplement the
SPT borings These explorations, which included tip resistance, sleeve friction and
selected pore pressure dissipation measurements, extended to approximate depths of
105 to 140 feet below the ground surface.
Laboratory Testing
The laboratory testing program, generally performed by S&ME or GET Solutions,
included extensive index property tests (gradation analyses, Atterberg limits
determinations (liquid and plastic), and natural moisture contents). The laboratory
program also included compaction testing (moisture versus compacted density),
California bearing ratio, chemical tests (pH, resistivity, sulfides, chlorides, organics),
one-dimensional consolidation, and U-U triaxial tests.
The results of these tests are included in the Appendices of the HDR geotechnical
reports
SUBSURFACE CONDITIONS
The conditions indicated by the borings are consistent with those described in the
geologic discussion, and are discussed in considerable detail in the HDR Reports.
Specifically, much of the near-surface zones consist of highly variable artificially placed
fill. At the higher elevations, this probably represents embankment fill placed during
earlier highway construction. At lower elevations, the fill could be the result of either
earlier roadway construction, or the myriad development projects which have occurred
over the years.
Below the fill, interbedded layers of clays and sands are present down to the Yorktown
Formation. These layers can be divided in the upper sand and clay layers, characterized
by very soft and loose consistencies, and the lower sand and clay layers, which are
Geotechnical Report - Final I-264, Project 0264-134-102

typically loose to medium dense, or soft to medium stiff, with sporadic stronger and
weaker outliers. All of these natural strata represent the younger Quaternary geologic
units described above, and are considered subject to settlement under loading.
The deepest borings penetrated into the Yorktown Formation. These strata are mostly
medium dense to dense silty or clayey sands or sandy silty clays, with sporadic shell
fragments. Blow counts range between about 6 to 30, and average in the teens. The
significant presence of fines coupled with the known preconsolidation stress history of
these soils make these materials somewhat unusual, in that their strength is typically
greater than the SPT blow counts would suggest. Similarly, despite their sometimes
sandy and shelly composition, they tend to be somewhat to highly impermeable.

SECTION 2
GEOTECHNICAL RECOMMENDATIONS
SITE PREPARATION AND GRADING
The bridge sites should be maintained in conditions that will assure proper drainage and
comply with applicable environmental regulations throughout construction. Based on the
design using drilled shafts and driven piles, we expect that excavation and grading will
generally be limited to the approaches and abutments, and are not expected to be deep.
To assure safety, all excavations must be shored or appropriately laid back to prevent
sloughing or lateral displacement and to maintain safe working conditions. Site work
must comply with OSHA regulations, specifically 29 CFR Part 1926, which requires that
the soil be classified in the field by a “competent person.” Because a competent person,
as defined by the regulations, must have the authority to take prompt corrective action,
personnel filling such a role should be employed or retained by the contractor and be on-
site on a regular basis during performance of the work.
Design of temporary support measures are generally the responsibility of the construction
contractor. Any required excavation support, both temporary and permanent, shall be
designed in accordance with applicable AASHTO, VDOT and industry standards.
Contractor-designed temporary support may be accomplished using sheet piles, timber
sheeting, or soldier piles and lagging, or other feasible means. Sheeting may need to be
braced or tied back, depending on construction sequence, the soil heights to be retained,
and adjacent surcharges such as traffic or existing structures.
After clearing and grubbing the limited areas to receive new fill, the stripped surfaces
should be examined by a geotechnical engineer to assure the exposed grade is suitable to
begin placement of new fill. Any highly organic or debris-laden soils should be undercut
to reasonably clean materials. It must be anticipated that even with removal of organic
and other heterogeneous materials, the surface will be very moist to wet, and in many

locations, very weak. As such, establishing a base acceptable to begin filling will most
likely require use of special procedures, such as end-dumping a “bridge lift” and
displacing the muck or mud, the use of geotextile reinforcement, or perhaps other
methods. Whichever method is used, the base of the embankment should consist of
freely draining granular materials to provide strength, prevent wicking of moisture up
through the fill, and to provide a conveyance for groundwater escaping the underlying
soils as they are compressed.
Depending on availability, construction schedules, and prevailing weather conditions at
the time of construction, it may prove beneficial to use alternative fill materials that are
not susceptible to moisture, and can stabilize soft subgrades. Such materials include a
number of aggregates mixtures, fly-ash-based flowable fill, and proprietary lightweight
products (geo-foam, foamed concrete, etc.); however, use of such products must consider
their potential buoyancy during high-water flood conditions.
Standard earthwork procedures require fill placement to be controlled, and its degree of
compaction tested, to assure minimum standards are met. Specifically, each lift of fill
must be compacted to at least 95 percent of the theoretical maximum dry density, as
determined by VTM-1 or VTM-12 (~standard Proctor), at a moisture within 20 percent of
the optimum moisture content. The subgrade, as well as all base and subbase layers, shall
be compacted as required by VDOT’s Road and Bridge Specifications. Materials shall be
placed in approximately level layers not exceeding 8-inches, loose thickness, with the
density and moisture after compaction verified by a qualified soils technician prior to
placement of successive lifts.
BRIDGE FOUNDATIONS
Materials competent to support the anticipated loads are generally deep, typically starting
from about 40 to 70 feet below grade, and as such deep foundations are required. In
consideration of the subsurface conditions, we recommend that the bridge substructures
be founded on driven piles (Precast Prestressed Concrete - PPC), or drilled shafts. While

the foundations will in most cases bear in the pre-consolidated Yorktown Formation, the
conditions at the bridge over the former NS Railway (B602) are more favorable, and
light to moderately loaded piles are expected to develop the required resistance above the
Yorktown.
The factored loads provided by the structural engineers include reactions for both piers
and abutments. These values were increased, where applicable, to include the predicted
drag loads (“downdrag”) as discussed later in this report. The final design is based upon
PPC piles, although as the design was being developed, both steel HP sections and PPC
piles were considered. Final selection of PPC piles was based on simplifying the project
by using one pile type, as well as the economy usually associated with concrete over
steel.
There are several locations where space and constructability concerns strongly favor use
of drilled shaft foundations. These include the piers of the bridges along I-264 (B601 and
B602), as well as Pier 1 of the flyover bridge (B603) which is located in the median of I-
264.
Drilled Shafts
As indicated, limited space and constructability concerns favor drilled shaft
foundations for certain piers of three of the bridges. The structural engineers
indicated desired shaft sizes of 4’-6”, 4’-0” and 6’-0” for B601, B-602, and B603,
respectively, to accommodate the columns they will support, as well as to develop
the axial, shear and moment capacities required by the structural design.
Evaluation of factored resistances for axial loading was performed in
conformance with “LRFD Bridge Design Specifications, 2014,” including interim
revisions, published by AASHTO. The code adopts the methodology described in
the 2010 FHWA Publication covering the design and construction of drilled
shafts, by Brown, Turner and Castelli;1 however, the method and resistance
factors used in our analysis are those specified in the current Code.
Geotechnical Report - Final I-264, Project 0264-134-102
Bridges B601, B602, B603 and B621 Virginia Beach, Virginia

The code requires the following resistance factors when calculating the
geotechnical axial resistance of a drilled shaft, as listed in Table 10.8.3.6.3-1:
Skin Resistance, Cohesive Soil: 0.45
Skin Resistance, Non-Cohesive Soil: 0.55
Tip Resistance, Cohesive Soil: 0.40
Tip Resistance, Non-Cohesive Soil: 0.50
The shafts will need to be extended into the Yorktown soils to develop sufficient
skin friction, and combined with moderate end bearing, develop the necessary
factored resistance. Spreadsheets showing example calculations are provided in
the Appendix. Recommended depths, sizes and factored resistances are as
provided in Table 2, below. The sizes and depths were selected based on the
desired shaft sizes and ranges of resistances indicated by the structural engineers.
Other combinations of diameters, depths, and factored resistances can be
evaluated, as needed.

The lateral response of the shafts to the shear and moment reactions indicate
anticipated horizontal deflections of less than 0.5 inch, which are considered
acceptable from a geotechnical standpoint.
The potential unbalanced hydrostatic pressures in holes of the depths
recommended will be quite high, which introduces a risk of side collapse, blow-
in, or boils. Accordingly, we would expect that the “wet method,” in which a
slurry is used to maintain the holes during drilling, reinforcement placement and
concreting will be proposed by the drilled shaft contractor. However, other
methods, particularly ones which combine use of casing and slurry, may be
feasible. If slurry is used, its selection should consider the anticipated timing of
drilling, rebar cage installation, and concreting, as well as subsurface conditions
such as soils types and strengths, water salinity, etc. The time it will likely take to
construct each shaft favors polymer type slurries, as these products generally do
not “cake” on excavated shaft walls, nor do they require periodic agitation.
All shaft excavations should be maintained by casing and/or slurry, as
appropriate, during construction. Even so, it is essential that reinforcing steel and
concrete be placed as soon as practicable after drilling to prevent degradation of
the shaft excavations. We anticipate that, as is typical with this method, a short
length of casing will be placed at the top of the excavation after commencing
drilling to maintain the size and shape of the hole, with slurry used deeper in the
shaft excavations. Slurry is pumped from a nearby tank or reservoir as the hole
progresses, which is recovered for reuse during the concreting process.
With the sensitive subsoils, and the loss of integrity and capacity that can occur
during foundation construction, the specifications should require the contractor to
have demonstrated experience installing deep drilled shafts in the Hampton Roads
area. Additionally, the on-site inspection personnel should be experienced in
identifying local soils, in particular the Yorktown Formation, which will have to
be identified from the spoils. Careless installation procedures and inexperienced

- 13 -
personnel could result in soil inclusions and shafts bearing on disturbed materials,
poor rebar-concrete bonding, as well as other defects.
We understand that the upper 25 feet of the shafts for the B602 piers will be
constructed with permanent casing, due to the close proximity of the light rail
infrastructure to be constructed in the near future. The capacity calculations for
this structure conservatively omitted any skin friction contribution within this
range. There may be other locations where more extensive shaft casing, either
temporary or permanent, will be warranted to protect nearby utilities, existing
structures, etc. If permanent casings are required at locations other than B602, the
Engineer should review the situation and determine if design revisions are
warranted.
Driven Piles
The abutments of all four structures, piers 2 and 3 of the flyover bridge, as well as
all of the bent-type substructures of the wharf bridge, will be supported by driven
piles. The foundation designs use battered piles to resist lateral and transverse
loading; all piles will provide varying degrees of axial support. We understand
that the resulting lateral and transverse reactions per pile to be inconsequential
with respect to geotechnical response. Factored loads were provided by the
structural engineers, and combined with factored drag loads, as applicable, were
used to evaluate pile sizes and anticipated driven depths to achieve the required
per-pile nominal resistances.
The calculations used Φ=0.65 as the resistance factor, in accordance typical local
practice and AASHTO LRFD Table 10.5.5.2.3-1. This factor requires dynamic
testing during test pile installation, coupled with signal matching of the data to
verify pile capacity. As noted in the AASHTO table, dynamic testing and signal
matching must be performed on two piles for every site condition, and for at least
2 percent of the total production piles, whichever is greater. Excepting the wharf
Geotechnical Report - Final I-264, Project 0264-134-102
Bridges B601, B602, B603 and B621 Virginia Beach, Virginia
- 14 -
bridge, we would envision dynamic testing of one (1) or two (2) piles from each
substructure, which should meet or exceed the minimum requirements.
Considering the large number of closely spaced bents for the wharf bridge, we
recommend selecting a test pile quantity meeting the 2 percent requirement,
located at representative locations across the foundation plan area.
Note that the AASHTO code allows use of higher resistance factors for higher
quality control levels of production piles. A factor of Φ=0.75 may be used if
dynamic testing is performed on all production piles, or if one successful static
load test is completed for each site condition. A resistance factor of Φ=0.80 may
be used if both a successful static load test, and at least (2) dynamic tests, are
completed for each site condition. While static load tests are often not cost
effective, in some cases the additional dynamic testing to allow a factor of Φ=0.75
may be.
The design process has gone through several iterations with respect to pile drag
loads (sometimes called downdrag or negative skin friction). Initially, the pile
loads considered relatively minor amounts of drag load, based upon the
presumption that the upper regions of the piles would be coated with bitumen or a
similar friction-reducing material. VDOT subsequently requested that the design
be modified to forego coatings, and the pile resistances were increased to resist
the full anticipated drag loads. While this approach was generally acceptable, the
loads and resulting embedment lengths were quite large, especially for the flyover
bridge, so the decision was made to employ stand-by or “quarantine” times, on
the order of 3 to 6 months or more, to allow all of the ~1 to ~2 feet of primary
settlement to occur prior to driving the affected piles. Although secondary
settlement will still occur over the course of several decades after construction, its
magnitude is quite small, and is not considered problematic. Accordingly, the
anticipated drag loads were removed from the abutment piles for bridge B603.
Geotechnical Report - Final I-264, Project 0264-134-102
Bridges B601, B602, B603 and B621 Virginia Beach, Virginia
- 15 -
Per AASHTO, where drag loads are considered, they must be increased by a
factor of 1.4 (AASHTO Table 3.4.1-2) and added to the factored axial (structural)
load. This combined load is then divided by the resistance factor appropriate for
the level of quality control, in this case 0.65; the resulting value is the Nominal
Axial Resistance which must be attained in the field. Expressed as an equation:
Structural + Drag Loads (Factored) ÷ Φ = Nominal Resistance (construction)
The computer program “APILE,” developed by Ensoft. Inc, was used to predict
pile penetration depths needed to attain the required nominal resistances. The
loads, resistances, and estimated embedments are summarized in Table 3, located
immediately behind the text of this report. APILE output sheets showing
representative calculations are provided in the Appendix.
The surface elevations across each bridge location vary from the average values
considered in the analyses. The elevations range from about elevation 17, to as
low as about -10 in the ponds. As most of the capacity develops at greater depths,
the tip elevations are a more reliable reference point for predicting pile lengths.
Surface elevation irregularities are expected to have little effect on pile capacities.
The soft to moderately consolidated soil conditions throughout the profile do not
suggest unusual or difficult driving; however, should there be any unusual
observations during pile installation, such as unexpected soft or hard zones, lateral
drift or “kick,” etc., they must be evaluated by VDOT and the geotechnical
engineer to determine if corrective procedures or additional evaluations are
warranted. The PDA data should be examined by experienced personnel to
determine pile integrity, and to evaluate the possibility of pile driving damage.
As a precursor to test pile installation, the contractor shall propose equipment for
driving, substantiated by wave equation analysis. During driving and re-striking
the test piles, the entire procedure shall be monitored by dynamic testing, to verify
Geotechnical Report - Final I-264, Project 0264-134-102

- 16 -
pile stresses and capacities, as well as hammer efficiency and performance. The
estimated depths/elevations indicate the depths at which the nominal axial
resistance values are predicted to develop for the recommended pile sizes. Pile
order lengths are typically established by the Engineer subsequent to the
contractor’s analyses and the pre-production wave equation report. Test piles are
typically ordered at least 10 to 15 feet longer than predicted embedment to assure
sufficient lengths to attain capacity.
After the minimum wait time and pile re-striking, the nominal capacity shall be
refined by signal matching analysis of the dynamic data. As set-up or “freeze” is
expected to contribute significantly to the nominal resistances, the time interval
for re-striking test piles should be at least 5 full days (120 hours) after the end of
initial drive, as required by VDOT standard specifications, unless a longer period
is directed by the Engineer. Upon review of the driving records, dynamic data,
and signal matching analyses, the Engineer will set pile order lengths and the
criteria for installing production piles.
Subsequent to the first submittal of this report, VDOT requested that we evaluate
whether some pile depths could be shortened due to the set-up tendencies of the
local soils. The Department provided historical records of dynamic pile test
results, both after initial drive and at the beginning of restrike. Of particular value
were borings showing the subsurface data at the test locations. Our analysis
suggests that, other parameters remaining consistent, capacities after set-up
varied, but were on the order of 128% to 185% of predicted values using a
traditional analysis with APILE. We conservatively increased the predicted skin
friction in the bearing zones by 25%, i.e., skin friction values of 125% of the
traditionally derived values. These increases were only applied to the Yorktown
bearing strata.
