11.0 Fee Development
The scope of geotechnical services is determined after consultation with the project team to
determine the size, type and loading of the proposed construction combined with the anticipated
site grading measures necessary (e.g., depth of cut and fill). In addition, any special
considerations or concerns associated with a specific project that may require special exploration
measures are discussed (e.g., the presence of sinkhole, mine spoil, or shallow rock). Once the
necessary information is obtained and reviewed, and exploration plan with the appropriate
number, depth, and type of borings (or other appropriate exploration means) is developed. Once
the exploration plan is established, the cost of each component of the exploration is determined.
The scope for special inspections is determined after consultation with the project team to
determine the schedule, type of construction, scope, and frequency of testing of the proposed
schedule. Once the information is obtained, a man power estimate is developed based on
schedule and percentage of overall construction price.
12.0 Field Reports
All field generated inspection reports are hand written by the assigned inspector with a copy
retained on site. Reports are turned into the office daily. Once in the office, reports are typed,
reviewed by project managers, and electronically mailed to the respective individuals on the
distribution list within two days of the written inspection report date.
GEM strives to maintain a two day turnaround for providing typed field reports and a one day
turnaround on compressive strength test results for concrete, mortar, and grout.

Project Description
The planned construction included both new south and north additions. The south addition consisted of
a new gallery entrance and lobby leading to a main gallery with a temporary exhibit gallery, a sunken
court (open air), and mechanical space on the lower level. The north addition consisted of two above
grade levels and a below grade level. The above grade levels included a lobby/entry area, auditorium,
museum shop, kitchen, dining area, and a café on the first level and a gallery and sculpture terrace and
offices on the second level. The below grade level included educational uses, art store, meeting room,
storage, and mechanical space.
The new construction included many design challenges, including: large cantilevered loads; heavy
concentrated loads necessary to create large open spaces; existing spread foundation systems bearing
on loose sands; new loading adjacent to existing sensitive structures; existing fill (including old basement
fill associated with historical structures); numerous active utilities where disruption in service was not
acceptable; deep new fill in existing basement areas; and retention systems to protect nearby adjacent
construction. Fieldwork had to be completed in a manner that did not disrupt museum functions while
also maintaining access to one of the most highly travelled areas on the University of Louisville campus.
Special location measures and coordination with public utilities and museum maintenance personnel
was necessary to identify and field locate the numerous underground utilizes that surrounded the existing
building.

Project Description
The condominium complex was located on the banks of Harrods Creek in an area where the slopes are sensitive to
changes and prone to failures. Frequently, the slope failures are precipitated by man-made changes, such as crest or
slope fills, toe cuts, or altering groundwater seepage patterns. For this project, the main contributors to the failure were
an unusual period of prolonged wet weather, high creek levels, repeated changes in creek levels (i.e., rising and falling
water levels), and the loss of a very large tree (and a couple of medium trees) that appeared to be anchoring the
naturally steep slope. Our exploration included obtaining subsurface information for use in the slope stability analysis
and installing slope inclinometers to better define the shape of the actual slope failure and to allow real-time
measurements of slope movements. The purpose of our exploration was to assess the likelihood slope movements
would imperil the condominium building at the crest of the slope and to develop subsurface and design information
that would be critical to a specialty contractor designing an appropriate remediation option. After defining the limits
and shape of the slope failure, subsurface conditions, soil design parameters, and likely remediation tactics that
would be successful for the project conditions, GEM solicited and evaluated bids from specialty contractors for
design and construction of a remediation system that would protect the building at the crest of the slope from future
movement.

Project Description
The project included a new 80,000 square feet, three-story hospital on Route 245 in Bardstown, Kentucky. The building
was a structure steel frame system supported on approximately 250 caissons socketed into the limestone bedrock
formation. To save the owner and construction manager time and money due to the late winter start, GEM value
engineered the caisson foundations and was able to significantly reduce the originally specified rock socket depths.
In addition, GEM recommended stabilization of the building subgrade clay soils prior to the start of the foundation
construction with hydrated lime. This not only provided a firm working surface for heavy caisson construction
equipment during the winter and spring months but also reduced the swell potential of the on-site, high-plasticity
clays. During the course of the project GEM provided full-time inspection services for a period of 4 months during the
site development and foundation installation. Other special inspection and testing services included masonry
monitoring, structural steel inspection and testing and fireproofing inspection.

Project Description
The Hardin County Landfill is located in terrain characterized by deep hollows formed primarily by surface water runoff.
The remnant ridge tops are capped with a thin layer of plastic clays and limestone. Progressing down the slopes, the
rock transitions to siltstone, then to shale. Most of the existing slopes are steep (on the order of 1.5H:1V) with minimal soil
cover, making access difficult. The shale weathers to form weak fissile, highly jointed, low durability shale and silty clay
soils that commonly experience landslides if exposed on slopes. The slopes on this unit are covered by narrow
landslide blocks, as indicated by fresh scarps and/or tilted trees. Slope failures are common. Landslides in the shale
member occur naturally as colluvium moves down the slope or as toe areas are undercut by erosion. Frequently, the
slope failures are precipitated by man-made changes, such as crest or slope fills, toe cuts, or altering groundwater
seepage patterns, all which occur during construction. The purpose of our geotechnical exploration was to obtain
and evaluate subsurface information in order to assess slope stability, identify geotechnical concerns that may affect
the proposed construction, and develop design and construction recommendations for site preparation and fill
construction. GEM designed the soil and rock cuts for the landfill to minimize disturbance and construction costs.
GEM also conducted construction material testing during construction of the landfill. These services included
subgrade evaluation, density testing, visual observation of shot-rock/soil fill, geosynthetic liner observation and
testing, and laboratory testing.

Project Description
The project consisted of a large, multi-faceted expansion to the existing church and school facilities of St. Mary of the
Knobs Catholic Church that included a new sanctuary, classroom/office space, and a gymnasium, as well as
baseball fields and a track and field area. Site development was significantly impacted by the existing topography,
based on over 100 feet of relief. In addition, new embankments would be constructed in the athletic field area and
a new access roadway requiring nearly 30 feet of fill would be constructed over an existing creek area. Cuts as
deep as ~30 feet would be necessary for the new gymnasium.
The slopes presented challenges in the field work, many areas made very soft near the surface due to heavy rain
storms around the time of exploration. Topsoil depths varied widely, with up to 4 feet encountered in a drainage
swale. Low plasticity clays transitioned into highly to completely weathered siltstone which was penetrated to a
maximum depth of approximately 13 feet below the surface with a hollow stem auger. The siltstone was cored to a
depth of 30 feet in the gymnasium area to investigate the hardness of the rock and ascertain possible rock removal
techniques.
Slope stability was the primary concern of the project along with concerns associated with blasting and overshot
rock. New soil embankment slopes were recommended to be no steeper than 3H:1V, with shot rock slopes to be no
steeper than 2H:1V. Cut slopes in competent siltstone could be as steep as 30 degrees off vertical, with minimum 5foot benches to be provided due to the likelihood of occasional future spalling. The architect was requiring a 4-foot
thick layer of soil beneath all new structures to more easily facilitate installation of utilities, making concerns
associated with variable bearing conditions not applicable.

Project Description
The project consisted of a welcome center and a new entry to the campus as part of the Seminary’s celebration of
150 years. The welcome center was a 2-story building with a partially below grade lower level. The new entry
included landscape walls, a gatehouse, and tower.
A few of the challenges for this project included: highly variable rock conditions due to the presence of karstsusceptible limestone; nearby adjacent buildings; existing utilities that traversed the planned construction and could
not be relocated; and deep existing fill at the new campus entry.
To address the highly variable rock conditions, additional rock soundings were added to supplement the soil test
borings. Both rock pinnacles and slots were detected. Because drilled piers were considerably more expensive than
conventionally-excavated rock-bearing foundations, a foundation design that accommodated either foundation
type was provided. Depending on the actual conditions encountered at the time of construction (i.e., deep or
shallow rock), the appropriate foundation type was selected. The presence of two adjacent buildings with shallow,
soil-bearing foundations and deep rock conditions required that drilled piers be used next to these buildings (i.e.,
potential to undermine existing foundations with conventional excavations). Foundation locations had to be
modified in the field to accommodate existing utilities that could not be relocated, and careful observation of the
subgrade support conditions was implemented to reduce the concerns associated with the existing utilities. The
presence of deep, poorly compacted uncontrolled fill in the new entry area required the use of rock-bearing
foundations for the planned tower because of the tall, slender, settlement-sensitive nature of the tower.
The following services were provided during construction: evaluation of drilled pier and rock-bearing foundations;
subgrade evaluations for slabs and new pavements; concrete testing and reinforced steel observations of
foundations, basement walls, and floor slabs; floor flatness testing; and structural steel observations.

Project Description
A mid-rise condominium building currently was designed and constructed in Louisville Kentucky. The building has 12
above ground levels and three underground garage levels. An attached open terrace with a swimming pool faces
the interior of the property. Maximum column loads exceed 1000 kips. Deep fill was required along one site of the
building over an existing stream and valley area. GEM provided an extensive subsurface exploration including: soil
borings, core drilling, air track drilling, test pits and hand auger borings. The site was underlain by limestone with a
number of sinkholes, springs & other karst features. The rock surface was found to be highly weathered and irregular.
A stream also ran across the site. Recommendations were developed for high capacity rock-bearing footings & for
the basement wall/backfill system. After the start of construction, the design was changed to add several additional
floors. GEM was able to assist in redesign of the existing foundations to accommodate the increased loads. GEM also
designed a special temporary foundation for support of the tower crane erected adjacent to the basement backfill
zone. Special inspection and testing services during construction included: grade raise fill, foundations, conventional
concrete, post-tensioned concrete, and structural steel.

Project Description
A new conference center was designed and constructed at E. P. "Tom" Sawyer State Park in Louisville, Kentucky. The
Sawyer Hayes Community Center adds a new dimension to the park and offers an outlet for passive enjoyment of
the scenery and wildlife. The center was a $2 million project with $1 million donated by Mrs. Jean Sawyer Hayes
and $1 million contributed by the Commonwealth of Kentucky. The center includes a reception hall that can seat
up to 250 guests. Attached to the reception hall is a spacious trellised outdoor terrace that overlooks the natural
forested landscape of the park. Additionally, there is a smaller meeting room that seats 30 and opens up to a small
terrace for outdoor activities or meetings. The community center has a catering kitchen and front lodge area for
relaxing near a large fireplace.
The site formerly was occupied by the old Central State Hospital which included several multi-story buildings that
were demolished in the 1990’s. The old construction materials (primarily concrete and brick) were left at the
site creating a layer of uncontrolled fill over the planned new building area. GEM conducted a multi-phase
subsurface exploration including: test borings, test pits, ground penetrating radar surveys, and air track drilling to
evaluate the condition of the existing fill and remnant structures. Based on these findings, the building location was
moved to a new area with less prior disturbance. Recommendations were developed to improve the subsurface
bearing characteristics by undercutting of the old fill material and replacement with new engineered fill.
Monitoring, testing and special inspection services were provided by GEM during construction. The center was
opened in the Spring of 2009.

Project Description
The project consisted of improvements to the existing terminal apron and central access taxiway at Owensboro
Daviess County Regional Airport. Due to the airport recently securing an arrangement with Allegiant Airlines, an
evaluation was needed to determine the condition of the existing pavement and its suitability for the increased
airplane traffic. This new traffic consisted of 2 departures/arrivals of an MD-83 aircraft (weighing 161,000 pounds) per
week. In addition to the need for a stronger pavement section, a new area of pavement was needed to give the
MD-83 a larger turning radius between existing taxiways for easier access to the terminal apron.
A total of 15 borings were drilled throughout the existing apron to evaluate soil conditions. Firm to stiff, silty clays were
encountered. An additional 8 locations selected for concrete cores to ascertain the strength and thickness of the
existing concrete. The oldest concrete from original construction was placed in the 1940’s, was generally in good
condition, and exhibited compressive strengths of over 10,000 psi. Surprisingly, no granular base was observed to be
in place underneath any of the concrete pavement. Later expansions of the original apron and taxiway actually
showed concrete in generally poorer condition with lesser strength. A visual evaluation was conducted of all
individual slabs and joints. All data and observations were then evaluated with the current Federal Aviation
Administration’s current Advisory Circular on airport pavement design to examine rehabilitation options including an
overlay or full-depth replacement of the existing pavement.
Design recommendations on rehabilitation options were given in the final report. Flexible pavements were not
recommended for the project due to the nature of the heavy aircraft loading. Rigid pavement sections included
recommendations for new pavement/full depth replacement and rigid overlay of the existing pavement. Joint
spacing, steel requirements, and rehabilitation of existing joints were also addressed.
Original pavement in generally good condition.

Project Description
Project consisted of a new 30,000 SF three story medical office building with partial basement in the Old Brownsboro
Crossing development in Louisville, Kentucky. The building had a steel frame structural system supported on
approximately 80 caissons installed into the karst limestone bedrock formation. GEM was able to value engineer the
caisson foundations to significantly reduce the rock removal depths originally assumed by the structural engineer. In
addition, GEM recommended a 2 feet upper layer of low-plasticity clay below the ground floor slab to reduced the
swell potential of the underlying high-plasticity clay soils. During the course of the project GEM provided full-time
inspection services for a period of 6 months during the site development and foundation installation. Other special
inspection and testing services included masonry monitoring, structural steel inspection and testing and fireproofing
inspection.

Project Description
A regional division of a national corporation moved their headquarters into an existing building off North Hurstbourne
Parkway on the eastern side of Louisville, Kentucky. Stormwater runoff from the large watershed surrounding the
building area flows into a series of detention basins that discharge into a sinkhole. Past flooding of adjacent paved
areas has been attributed to inflow exceeding the sinkhole capacity.
GEM Engineering, Inc. conducted a study to evaluate the existing drainage characteristics of the sinkhole, designed
an improved inlet system, supervised its construction, and monitored its performance. Our services included:
•
•
•
•
•
•
A review of available geologic and hydrogeologic information for characteristics of the rock formations
below the site and groundwater movement through the area.
A visual reconnaissance to provide information about specific site and area surface drainage conditions.
A physical exploration of the subsurface conditions to evaluate the upper rock surface, stability of active
throats, potential for collateral subsidence, and evidence of past development of the feature.
A dye test to evaluate primary sinkhole discharge locations.
Estimates of the short-term flow capacity of the sinkhole under varying improved conditions.
A design for an improved sinkhole inlet structure to reduce the potential for clogging, improve sidewall and
base stability, reduce internal erosion, and increase flow rates.
Following construction of the new drainage structures, water drains from the basins within hours instead of days and
no flooding of surrounding areas has taken place.

Project Description
GEM provided geotechnical exploration and construction quality monitoring services. Project consisted of a new
240,000 SF expansion to the existing South Wing of the Kentucky Fair and Exposition Center (KFEC) with associated site
improvements. Fast track project dictated the project staffing of up to three (3) GEM Technicians over a 3-month
period during the fill placement and installation of 350 caisson foundations. Fill placement for support of the new
Exhibit Hall floor slab utilized on-site clay soil-rock fill material. Special inspection techniques were required to verify the
adequacy and stability of the fill placed since the material was non-homogeneous in nature and precluded the use
of conventional in-place density testing. Over 20,000 cys of structural concrete was placed including 6000 psi for the
new Exhibit Hall Floor slabs. GEM performed floor flatness profiling of each slab placed using our in-house Floor IV
Profiler to verify compliance with the project specifications. Other special inspection and testing services included
masonry construction monitoring, in-place field density testing and sitework inspection and testing.

Project Description
The project consisted of a 6-story concrete reinforced, post-tensioned parking garage with compression and lateral
column loads in the range of 1,500 kips and 40 kips, respectively. The site had been developed and redeveloped
numerous times over the last 100 plus years. Many remnant structures, including cisterns and basements, were
present. Due to the high structural loads and the need for minimal vibrations, augercast piles were the
recommended foundation system.
Three existing buildings were located within 15 feet of the proposed structure, including a printing facility that was
very sensitive to vibrations from construction. Vibration monitoring was conducted at the printing facility to establish
background vibrations and to identify construction activities that could impact printing operations. A shoring system
was required to protect one building from the excavations necessary to construct the parking garage foundation
system. Special precautions were taken during augercast pile installation to ensure the existing buildings were not
damaged, including monitoring grout factors and spoil return during drilling.

Project Description
The Healing Place offers alcohol and drug addiction recovery services to Louisville’s homeless. Their current women’s
facility is substandard and overpopulated, thus creating the need for a new facility. A 73,000 square foot masonry
and steel structure with housing for over 175 women, a dining hall, several classrooms, a clinic, and an divisible
meeting room has been designed and constructed. The main building consisted of three, two-story wings connected
by hallway corridors. Challenges for this project included: loose sand deposits at or near foundation bearing
elevations, the presence of old fill, and buried structures from past land usage.
The project site had been previously developed as observed in aerial photos. Prior to construction the property was
being utilized as a truck parking lot. Subsurface borings indicated the presence of old fill and very loose sand layers
at or near foundation bearing elevations. Initial site development recommendations included: undercutting each
building pad below the bottom of foundations, compacting the loose sands at that elevations, and backfilling the
building pads with the undercut material placed in compacted controlled lifts. Due to budget constraints, an
alternative method was utilized. Since there where vast amounts of crushed asphalt stockpiled throughout the site,
this material was utilized to bridge over the loose sand layer. The old fill was removed, but the extensive undercutting
of the loose sand layers was avoided except in localized foundation locations.
The following services were provided during construction: evaluation of backfill materials; subgrade evaluations for
slabs and new pavements; concrete testing and reinforced steel observations of foundations, basement walls, and
floor slabs; masonry evaluations; floor flatness testing; and structural steel observations.

course and Inverted Rope Descent course. At the second and third sites, Thunderbolt Tower & Victory Tower ROTC,
load testing was performed on safety nets (Thunderbolt only) as well as selected hand railing members and platform
anchors. These towers are utilized for rappel training exercises and the platform anchors are tie-off pull points for
rappelling. All load testing utilized a sand bag of established weight ranging from 200 to 500 lbs. and either hung from
a specific item tested or dropped from a specific height into a net. At completion of testing, observations were made
and reported of any obvious modes of failure or permanent deflection detected. This testing program disclosed
several failed or weakened members that were immediately replaced or repaired to ensure the safety of the soldiers
using the training equipment.

Project Description
Four historic buildings were renovated and combined to house a museum. Roughly 50 percent of the upper interior
masonry party walls were removed to create exhibit spaces. An additional floor was added bringing the total
building height to 5 stories. New columns were added at the basement level in cutout sections of the existing party
walls. Maximum new column loads were on the order of 250 kips. Special subsurface exploration techniques
including low clearance drilling equipment and hand auger borings were necessary to gather soil information inside
the structure for design of new foundations. An extensive sampling and testing program was undertaken to evaluate
the condition of the existing masonry walls and wood floor beams, some of which had been damaged by a past fire.
Based on the test results, much of the existing structure was found to be structurally sound; resulting in significant cost
savings by eliminating planned supplementary structural supports. New columns were supported on auger cast piles
that were installed inside the existing basement using low overhead clearance drilling equipment. During the course
of construction, GEM provided inspection services for approximately 2 years. Inspection and testing services included
foundations, masonry, concrete, structural steel inspection and fireproofing.

Project Description
GEM conducted a design phase geotechnical exploration and provided construction phase monitoring and testing
for the E. ON Data Center in the Kingbrook Business Park in Simpsonville, Kentucky. The project included a single-story
data center constructed of concrete tilt-wall panels. Pavements included an employee parking lot, driving lanes,
and truck loading areas.
The geotechnical exploration identified shallow rock, potential karst activity, and spring activity on the site.
Foundations were designed to accommodate the shallow rock and to provide adequate means to provide
drainage for springs that may be present under the building. Pavements were designed to incorporate a geotextile
fabric and “surge” stone in lieu of KYTC No. 3 stone for cost savings. GEM provided on-site recommendations as
conditions arose regarding possible karst features and addressing the drainage of groundwater from springs as they
were discovered.

Project Description
The old Crestwood Elementary School was demolished and replaced with a modern facility that was completed in
2008. The project consisted of a new 85,415 total sq. ft. L-shaped 2-story building with associated parking and
recreation areas. The buildings’ structural system consisted of shallow spread footings, exterior insulated concrete
formed (ICF) walls, interior masonry walls along with light gage metal roof trusses. GEM conducted a geotechnical
study for the ~22-acre site. The subsurface exploration included borings, soundings and rock cores at more than 60
locations. Engineering recommendations were provided for support of new foundations, floor slabs, and pavements.
Key geotechnical issues that were addressed by GEM included: remediation of old below grade walls, foundations
and other structures; stabilization of soft surface soils; shallow bedrock’ shallow groundwater; high plasticity clays; and
poor surface drainage.
During the course of construction, GEM provided full-time inspection services that started in July 2007 with the
monitoring of site development. Special inspection and materials testing services were performed to comply with the
requirements of the 2006 Kentucky Building Code. These services consisted of foundation installation monitoring,
resteel and concrete inspection, masonry observation and testing, and structural steel inspection. Other site
development inspection services included pavement subgrade evaluations, stone subbase and asphalt pavement
testing as well as site concrete inspections.

Project Description
GEM Engineering, Inc. was retained by Patrick Engineering, Inc., the project design engineer, to provide construction
testing and monitoring services for the first Costco Warehouse to be built in Kentucky. Construction extended over
period of approximately 1 year and included placement of 20+ feet of fill to form the building pad and rear parking
lot embankment. Earthwork began during January. At this time the ground surface was wet and compactable clay
borrow was not readily available due to wet weather conditions. Accordingly, GEM worked with the construction
team to utilize limestone shot rock as the primary embankment fill material. GEM monitored the composition, particle
size, lift thickness, and compaction of the shot rock to assure that a suitable base was achieved for the overlying new
structures. This process worked extremely well and allowed construction to stay ahead of schedule and to proceed
without significant weather-related during the rest of the winter and early spring months. Other services provided by
GEM for this project included: subgrade evaluation prior to shot-rock placement; foundation bearing evaluations;
concrete reinforcement monitoring; concrete quality control testing; weld inspection; masonry mortar/grout
sampling and testing; floor slab and pavement subgrade evaluations; asphalt density, extraction and gradation
testing; and fireproofing inspection.

Project Description
Low concrete compressive strength test results were reported on a project using a concrete mix design that had
previously produced consistently good results. Review of concrete slump, air content and temperatures all indicated
values within specification tolerances. The only difference detected from concrete batches achieving the specified
compressive strength was that the low strength concrete was placed by chute discharge, while most of the concrete
on the project had been placed by pumping. Specimens of concrete placed by both methods were obtained for
forensic analysis. Petrographic examination of the concrete indicated total air content of both specimens to be
within acceptable limits. However, the concrete place by chute displayed consistently smaller air voids that were
clustered around coarse aggregate particles reducing bonding to the cement-sand matrix and resulting in lower
compressive strength. Pumped concrete displayed similar total air content, but larger, better distributed air voids
producing increased strength. GEM’s analysis indicated that the air initially contained in the entrained voids of the
plastic concrete was redistributed by the high pressures of pumping allowing the design compressive strength to be
achieved. The client and concrete supplier were advised of the findings to enable review of admixture or coarse
aggregate interaction effects on entrained air dispersion.

Project Description
GEM conducted a design phase geotechnical exploration and environmental assessment, developed the
construction Site Safety and Health Plan, and provided construction phase monitoring and testing of drilled pier
foundations for this facility at the Louisville International Airport. The project included an approximately 460 feet x 120
feet, steel-frame, three bay, aircraft maintenance hanger with an attached administration/storage/parts “lean-to”
building. Pavements included: an employee parking lot, truck access, aircraft apron, east-west taxiway, widening of
existing Airport Security Road and conversion into a temporary taxiway, and a temporary taxiway tie-in to existing
permanent taxiway. The geotechnical exploration disclosed soft soil conditions and the need for significant
improvement in pavement & slab subgrade areas. Recommendations were developed and successfully
implemented for subgrade stabilization with a layered geotextile/limestone shot rock bridging system. Based on the
weak soil conditions and high column loads, GEM developed recommendations for supporting the hangar structure
on end bearing foundations (drilled piers/caissons) bearing on shale bedrock. Conditions related to past site use that
were delineated by the environmental assessment resulted in special precautions being exercised during drilled pier
construction to provide safe working conditions. GEM provided construction technicians with OHSA 40 hour
Hazardous Waste Operations Training for this phase of the work. GEM also monitored and tested the impacted areas
when they were exposed.

Project Description
The Boy Scouts of America developed a new 20,000 square foot (approximate) single story office building on an
approximate 3-acre parcel of land in eastern Jefferson County, Kentucky. Our geotechnical study disclosed that the
site was underlain by Osgood Shale and soils derived from Osgood Shale. For this project, the primary concern was
the shrink/swell characteristics of these materials. This behavior was confirmed by swell testing conducted as part of
the geotechnical study. In addition, the near surface soils were found to be soft in many areas of the site.
Improvement of these poor, near-surface conditions was also an important consideration. Design parameters and
construction recommendations were developed by GEM to address these conditions. A key recommendation was
that all foundations, floor slabs and other sensitive structures be underlain by a 2 feet (minimum) layer of nonexpansive soil and/or controlled fill. GEM was retained by the owner to monitor the construction process to confirm
that the problematic conditions were properly addressed as well as to confirm that other important elements of
construction were installed in accordance with the project specifications. Key elements that were monitored and
tested by GEM included: foundation bearing soils, foundation reinforcement, foundation and floor slab concrete,
structural fill compaction; parking lot and floor slab subgrades; and masonry wall mortar and grout.

Project Description
An apartment / commercial building was developed by Louisville Metro Housing Authority. The building was
designed by Kersey and Kersey of Louisville. The three-story building contains 22 apartment units and 3,500 square
feet of retail space on the first floor. After completion in 2009, the building won a New Landmark Award for
architectural design. GEM conducted a geotechnical engineering study for the project which included a
subsurface exploration and a determination of seismic site classification based on correlations between Standard
Penetration Test N-values and average shear wave velocity. Geologic conditions at the site consisted of unsaturated
and saturated soils overlying limestone bedrock. The saturated zone and bedrock were at depths of 7.5m (24ft) and
20m (65ft) at this site, respectively. The initial results indicated that the site was borderline class C and D.
Considerable cost savings could be realized if the lower classification could be confirmed with in-situ testing.
At many sites the Spectral Analysis of Surface Wave (SASW) technique with the utilization of portable energy sources,
such as hammers and weight drops, is sufficient to obtain 30m/100ft S-wave velocity soundings. At sites with high
ambient noise levels and/or very soft soils, these energy sources may not be sufficient to image to 30m and a larger
energy source such as a bulldozer is necessary. Alternatively, passive (no source) surface wave techniques such as
the refraction microtremor method can be used to extend depth of investigation at sites that have adequate noise
levels. After confirming that both of these methods were appropriate for the subject site, GEM worked with a
geophysical consultant to conduct in-situ seismic measurements. SASW data were collected along a single array in
the vacant lot at the northeast corner of Broadway and Shelby. Refraction microtremor data was acquired along
the sidewalk adjacent to Shelby. The refraction microtremor array started at Broadway and extended an entire city
block. Rock hammers, 3lb hammers and 12- and 20-lb sledgehammers and a Case 850G bulldozer moving forward 3
ft and backward 3ft were used as energy sources.
The average shear wave velocity to a depth of 100ft, VS100, was found to be 1,144 ft/s (349m/s) at the site.
Therefore, according to the 2000 IBC and 2002 KBC, the site is classified as D, stiff soil. VS100 is relatively insensitive to
the assumed VS of 2,000 m/s (6,561 ft/s) for bedrock. A 25% increase or decrease in the velocity of the bedrock layer
leads to a maximum 4% change in VS100 and does not change site classification. The very soft, near-surface, fill soils
at the site have the largest impact on VS100. Accordingly, it was found that if the soils in the upper 3.5m (11.5 ft)
were compacted to the point where the velocity of these units increased to 200 m/s (656 ft/s), VS100 would be 1230
ft/s (375 m/s) making the site Class C, very dense soil and soft rock.

Project Description
An apartment / commercial building was developed by Louisville Metro Housing Authority. The three-story building
contains 22 apartment units and 3,500 square feet of retail space on the first floor. After completion in 2009, the
building won a New Landmark Award for architectural design. Sanborn Maps indicated that the site formerly was
occupied by several buildings, several of which had basements and other below grade components. In 2003, GEM
worked with the Housing Authority to remove and re-fill the below grade remnant structures from the western portion
of the site. In 2004, GEM conducted a geotechnical engineering study for the project which included a
determination of seismic site classification based on correlations with Standard Penetration Test N-values. The initial
results indicated that the site was borderline class C and D. Considerable cost savings could be realized if the lower
classification could be confirmed with in-situ testing. GEM worked with a geophysical consultant to conduct in-situ
seismic measurements. Spectral Analysis of Surface Wave (SASW) techniques demonstrated that Class C would apply
if the soils in the upper 11.5 ft were compacted to the point where the velocity of these units increased to 656 ft/s.
Construction began in 2007. GEM provided field engineering services to confirm proper removal and backfilling of
remaining remnant structures, as well as construction material testing, and special inspections.

Project Description
GEM conducted a design phase geotechnical exploration and provided construction phase monitoring and testing
for the Middletown Target Shopping Center in Louisville, Kentucky. The project included a 128,000 square foot
shopping center of CMU and structural steel construction. Pavements included an customer parking lot, driving lanes,
and truck loading areas.
The geotechnical exploration identified shallow rock and deep uncontrolled fills from the previous shopping center
that occupied the site. Extensive testing was conducted to explore the extents of the fill and its potential impact to
the new store. The foundations were designed to address the uncontrolled fill and the shallow rock present on site to
provide an economical solution for the particular site conditions.
GEM provided experienced engineers, project managers, welding inspectors, floor flatness technicians, as well as
concrete and soils technicians to observe, report, and provide solutions to meet the needs of the project schedule
while reducing the overall costs.
