SC-3
shall not be considered sufficient basis for claims for
additional compensation for extra work or for increasing the
pay quantities in any manner whatsoever, unless the
obstruction encountered is such as to necessitate
substantial changes in the lines or grades, or requires the
building of special work, provisions for which are not made
in the plans and proposal , in which case the provisions in
these specifications for extra work shall apply.

PROPOSED 1.5 MILLION GALLONS PER DAY EXPANSION
EAST DISTRICT SEWAGE TREATMENT PLANT
IBAYTOWN, TEXAS
This report presents the results of a geotechnical investigation performed at the
proposed site of the expansion of the existing City of Baytown East District Sewage
ITreatment Plant (EDSTP) . The existing EDSTP site is located about 1.000 feet south-
east of the intersection of State Highway 146 and Ferry Road in Baytown. Texas.
I The proposed expansion facilities are described below. The proposed expansion
facilities dimensions/elevations provided below are approximate only and are based
upon preliminary design drawings. The facility preliminary designs addressed in
Ithis
report are subject to revision based upon final design considerations.
s Treatment Module
A 60 foot to 120 foot wide. 130 foot to 220 foot long, 18 foot high reinforced
I concrete Treatment Module is to be constructed at the northwest side of the exist-
ing site. The elevation of the existing ground surface at the proposed Treatment
Module site varies between about elevation +6 feet MSL and elevation +10 feet MSL.
I An existing asphalt paved parking area exists at the northwest side of the pro-
posed Treatment Module site. The Treatment Module will be constructed immediately
adjacent to the west side of an existing Clarifier/Aerator. The Treatment Module
is to be founded on a slab foundation bearing at about elevation -1 foot MSL
I i .e. , sidewall top elevation of about +17 feet MSL) . Construction of the Treat-
ment Module slab foundation at elevation -1 foot MSL will require the excavation
of seven to 11 feet of existing overburden soil . The embedment depth of the
I Treatment Module slab will be about nine feet below the existing average site
grade elevation of approximately +8 feet MSL.
I
Digester
A 55 foot wide. 75 foot long. 18 foot high reinforced concrete Digester is to be
constructed at the east central side of the proposed EDSTP expansion site. The
proposed Digester site is located in an open area with low maintained grass. The
I surface elevation of the existing site ground surface at the proposed Digester
site is about elevation +7 feet MSL. The Digester is to be founded on a slab
foundation bearing at about elevation -4 feet MSL (i .e. . sidewall top elevation of
I about +14 feet MSL) , with about 11 feet of embedment below the existing site grade
elevation of +7 feet MSL.
I
a Entrance Works
A 20 to 48 foot wide. 20 foot to 60 foot long. 12 to 21 foot high reinforced
concrete Entrance Works is to be constructed at the southwestern portion of the
proposed EDSTP expansion site. The Entrance Works is to consist of an Entrance
I Works Basin and two Entrance Works Grit Chambers. The Entrance Works is to be
constructed in an open area with low maintained grass. The existing ground sur-
face elevation at the proposed Entrance Works site is about elevation +8 feet MSL.
IThe Entrance Works Basin is to be about 12 feet high and founded on a combination
of slab and strip/spread footing foundations . The Entrance Works Basin slab
foundation is to bear at about elevation +8 feet MSL with about two feet of embed-
ment' below the final site grade elevation of about +10 feet MSL. The Entrance
Works Basin footing foundations are to bear near elevation +2 feet MSL with about
eight feet of embedment below the final site grade elevation of about +10 feet 1

EXECUTIVE SUMMARY (Continued)
MSL. Construction of the Entrance Works Basin slab will require the removal of
existing fill to a depth of about seven feet (near elevation +1 foot MSL) and the
placement/compaction of select fill to about elevation +8 feet MSL. Construction
of the Entrance Works Basin footings will require the removal of existing fill
material down to natural in situ soil at a depth of about seven feet (near eleva-
tion +1 foot MSL) and the placement/compaction of select fill to about elevation
2 feet MSL.
The Grit Chambers are to be about 21 feet high and founded on footing foundations
which are to bear near elevation -1 foot MSL with about 11 feet of embedment below
the final site grade elevation of approximately +10 feet MSL. Construction of the
Entrance Works Grit Chambers will require the removal of about nine feet of exist-
ing overburden soil .
Office Building
A 35 foot wide. 55 foot long, single story Office Building is to be constructed at
the southwest side of the proposed EDSTP expansion site. The ground surface
elevation at the proposed Office Building site lies near elevation +8 feet MSL. A
three to four foot deep ditch is located at a portion of the proposed Office
Building site. The Office Building site is located at an area where refuse/fill
has been placed. The Office Building is to consist of a steel frame structure
with a floor elevation near the final site grade elevation of about +10 feet MSL.
The primary findings, conclusions and recommendations of this investigation are sum-
marized below.
Subsurface Soil and Ground Water Conditions
The site subsurface soils generally consist of:
Fill consisting of stiff to hard fat clay, lean clay with sand and sandy lean
clay and loose to very dense silty sand, clayey sand and silt with sand between
the ground surface and a depth of about ten feet,
very soft to hard fat clay and fat clay with sand between depths of about ten
feet and 53 feet.
stiff to very stiff sandy fat clay between depths of about 53 feet and 58 feet,
and
medium dense to very dense poorly graded sand with silt and silty sand between
depths of about 58 feet and the maximum boring depth of 70 feet,
The surficial fill layer described above contains gravel , shells, brick fragments,
concrete fragments, rubber tires, glass fragments. asphalt pieces, lumber, plastic
bags. tin cans, electrical wiring, plastic sheeting, paper and textiles.
The surficial site soils have a very high shrink/swell potential . The maximum
potential vertical rise of the upper eight feet of the site soils is about four
inches under a 1.0 psi restraining load.
Ground water was not encountered during drilling to a depth of about 40 feet below
the existing ground surface.
Excavation Dewaterinq
The static ground water table should be lowered to a depth of at least five feet
below the working surface during construction. It is expected that sumps and sump
pumps should be effective in removing ground water entering site excavations which
are 40 feet or less in depth.

EXECUTIVE SUMMARY (Continued)
Site Preparation - Treatment Module Area
It is recommended that the subgrade soils within the area of the proposed Treat-
ment Module slab foundation be prepared by:
removing the existing pavement and chain link fence from the proposed Treatment
Module area and stripping vegetation and organic top soil to a depth of at least
six inches.
establishing site drainage and installing storm water drainage structures if
required,
excavating the site soils as necessary to obtain the desired slab foundation
grade elevation of about -1 foot MSL for the Treatment Module and removing the
site fill (site fill at the Treatment Module may extend to an elevation of -4
feet MSL at some locations) .
providing temporary shoring and bracing in accordance with design requirements
for Type C soil as defined by OSHA.
establishing drainage ditches and sumps around the perimeter of the bottom of
the Treatment Module excavation and using sump pumps to remove water entering
the excavation.
proofrolling the exposed in situ soils with a 15 ton roller, observing the soils
during proofrolling to detect any wet, soft or pumping soils and treating wet.
soft or pumping soils with suitable drying or stabilizing agents or removing the
unsuitable soils and placing/compacting suitable earth fill or select fill .
compacting the exposed in situ soils to an in-place dry density equal to at
least 95 percent of the maximum standard dry density (ASTM D 698) at a moisture
content within ± 2 percent of the optimum moisture content.
placing/compacting select fill as necessary to achieve the final slab foundation
grade, and
constructing a four inch thick concrete mud mat over the slab foundation sub-
grade soil in order to serve as a working surface during slab foundation con-
struction and to protect the subgrade soils from drying/disturbance.
Care should be taken to assure that the excavation for the proposed Treatment
Module is not carried to significant depths below the existing adjacent
Clarifier/Aerator foundation unless adequate bracing/underpinning is provided.
If the exposed clay becomes unstable ("pumps" or "weaves") during site prepara-
tion, the construction contractor should be prepared to:
dry the exposed clays by discing these materials and compact these soils as
described above.
dry the exposed clays by blending a stabilizing agent (hydrated lime) with the
unsuitably wet soil and compact these soils as described above, or
remove any unsuitably wet clays and replace the wet clays with compacted select
fill having an acceptable moisture content.

EXECUTIVE SUMMARY (Continued)
Backfill around the Treatment Module walls should consist of suitable earth fill
or select fill compacted to an in-place dry density equal to at least 90 percent
of the maximum standard dry density (ASTM D 698) at a moisture content within ± 5
percent of the optimum moisture content.
Suitable earth fill should consist of on-site clays and sands which are free from
debris. Select fill should consist of a clayey sand or inactive lean clay with a
maximum liquid limit of 35 percent and a plasticity index range of eight to 20
percent. Suitable earth fill and select fill should be placed in eight inch thick
loose lifts and compacted to an in-place dry density equal to at least 95 percent
of the maximum standard dry density (ASTM D 698) at a moisture content within ± 2
percent of the optimum moisture content.
Site Preparation - Digester
It is recommended that the subgrade soils within the area of the proposed Digester
foundation slab be prepared as described above for the proposed Treatment Module.
Site Preparation - Entrance Works
It is recommended that the subgrade soils within the area of the Entrance Works
slab and footing foundations be prepared as described above for the Treatment
Module with the exceptions that:
the overburden soils should be excavated to depths of about seven feet in order
to provide for the removal of an approximately six to seven foot thick fill
layer, and
the overburden soils should be excavated as necessary to achieve the desired
foundation slab grade elevation (Entrance Works Basin slab foundation elevation
of about +8 feet MSL, strip/spread footing foundation base elevation of about +2
feet MSL and Entrance Works Grit Chambers footing foundation base elevation of
about -1 foot MSL) .
Site Preparation - Office Building
The shrink/swell potential of -the site surfi ci al active clays may be mitigated by
the use of site preparation techniques as described below, or alternatively, a
structural floor slab (suspended floor slab) may be used. Mitigation of the
shrink/swell potential of the active clays by using site preparation techniques
will require the placement/compaction of inactive select fill to a minimum 4.5
foot thickness at the floor slab areas of the proposed Office Building.
If the designer chooses to mitigate the high shrink/swell potential of the site
soils by excavation/fill placement. it is recommended that site preparation be
performed by:
removing the chain link fence and removing the site fill at the proposed Office
Building site (the site fill at the proposed Office Building site is expected to
extend to a depth of about ten feet) .
excavating the overburden soils to depths as necessary to achieve final grade.
proofrolling the exposed in situ soils with a 15 ton roller, observing the soils
during proofrolling to detect any wet, soft or pumping soils and treating wet.
soft or pumping soils with suitable drying or stabilizing agents or removing the
unsuitable soils and placing/compacting select fill or suitable earth fill ,
compacting the exposed in situ soils to an in-place dry density equal to at

least 95 percent of the maximum standard dry density (ASTM D 698) at a moisture
content within ± 2 percent of the optimum moisture content.
placing/compacting suitable earth fill or select fill as necessary to an eleva-
tion about 4.5 feet below the bottom elevation of the slab-on-grade floor, and
placing/compacting imported select fill to a minimum thickness of 4.5 feet below
the slab-on-grade floor base elevation.
Suitable earth fill or select fill properties and select fill placement/compaction
should be as described above for the Treatment Module.
Use of the site preparation technique as described above, should limit the maximum
PVR of the soils beneath slab-on-grade floors to about one inch.
1
As an alternate, a structural floor slab (suspended floor slab) may be used to
mitigate the site soil shrink/swell potential . If a structural floor slab is
used, site preparation at the Office Building site should be performed by:
removing the upper six inches of site fill material , and
establishing site drainage and installing storm drainage structures if required.
The surficial clay excavated at the site will not be suitable for use as select
fill at the proposed Office Building area.
The construction contractor may encounter difficulty in densifying/preparing the
surficial clays depending upon weather conditions and should be prepared to ade-
quately dry/stabilize any unstable surficial soils as described above for the
Treatment Module.
Backfill around the building walls should consist of materials placed/compacted as
described above for the Treatment Module walls.
Foundation Design - Treatment Module
The proposed Treatment Module will be constructed immediately adjacent to an
existing Clarifier/Aerator. Care should be taken to assure that the excavation
for the proposed Treatment Module is not carried to significant depths below the
existing Clarifier/Aerator foundation unless adequate bracing/underpinning is
provided. The Treatment Module may be supported on a reinforced concrete slab
founded at about elevation -1 foot MSL. The slab should be designed using a maxi -
mum allowable gross bearing pressure of 1,400 psf for axial compression dead loads
plus sustained live loads and 2,100 psf for axial compression dead loads plus
sustained and transient live loads.
With the above-recommended maximum allowable gross bearing pressures being used
for design:
the factor of safety against an Treatment Module slab foundation bearing failure
is at least 3.0 for axial compression dead loads plus sustained live loads, and
at least 2.0 for axial compression dead loads plus sustained and transient live
loads.
the Treatment Module slab foundation maximum total settlements should be about
1.3 inches at the center point of the slab and 0.5 inches at the corner of the
slab, and

EXECUTIVE SUMMARY (Continued)
the Treatment Module slab foundation maximum angular distortion (differential
settlement between two points on the slab divided by the distance between the
two points on the slab) should be about 1/1.184 (0.08 percent) .
The estimated maximum angular distortion of 1/1.184 (0.08 percent) compares fa-
vorably with a suggested maximum angular distortion of 1/200 (0.5 percent) .
About 30 percent of the total settlement of the Treatment Module slab foundation
is expected to be immediate (elastic) settlement and the remaining 70 percent of
the settlement is expected to be long term (consolidation) settlement. It is
expected that the long term settlement of the Treatment Module slab foundation
will occur over a period of about 14 months with the Treatment Module fully load-
ed. The accuracy of the time rate of settlement estimate is approximate only
because the number and sequencing of sand/silt partings, seams or layers and the
continuity of the partings, seams or layers will significantly influence the time
over which long term settlements occur.
Treatment Module piping connections should be designed to accommodate the expected
Treatment Module settlements . Treatment Module piping hookups should be made
I
subsequent to the dissipation of the elastic settlement.
If the estimated settlements and angular distortions provided above are deemed to
be excessive by the designer, the Treatment Module settlements may be reduced by
preloading the slab foundation area with a soil preload or by using an alternative
foundation system.
Foundation Design - Digester
The Digester may be supported on a reinforced concrete slab founded at elevation
4 feet MSL (depth of about 11 feet below the existing ground surface) . The
foundation slab should be designed using a maximum allowable gross bearing pres-
sure of 1.400 psf for axial compression dead loads plus sustained live loads and
2, 100 psf for axial compression dead loads plus sustained and transient live
loads.
With the above-recommended maximum allowable gross bearing pressures being used
for design:
the factor of safety against a Digester slab foundation bearing failure is at
least 3.0 for axial compression dead loads plus sustained live loads, and at
least 2.0 for axial compression dead loads plus sustained and transient live
loads,
the Digester slab foundation maximum total settlements should be about 0.2
inches at the center point of the slab and 0.1 inches at the corner of the slab.
and
the Digester slab foundation maximum angular distortion (differential settlement
between two points on the slab divided by the distance between the two points on
the slab) should be about 1/3.985 (0.03 percent) .
The estimated maximum angular distortion of 1/3,985 (0.03 percent) compares fa-
vorably with a suggested maximum angular distortion of 1/200 (0.5 percent) .
t It is expected that the ratio of the elastic and consolidation settlement of the
Digester slab foundation and the rate of settlement of the Digester slab founda-
tion will be as described above for the Treatment Module.
vi
HTS, INC.
EXECUTIVE SUMMARY (Continued)
Digester piping connections should be designed to accommodate the expected Diges-
ter settlements. Digester piping hookups should be made subsequent to the dissipa-
tion of the elastic settlement.
Foundation Design - Entrance Works
The Entrance Works Basin and Grit Chambers may be founded on a combination of
reinforced concrete slab and footing foundations as described below.
The Entrance Works Basin slab foundation may be founded at elevation +8 feet MSL.
The slab foundation should be designed by using a maximum allowable gross bearing
pressure of 800 psf for axial compression dead loads plus sustained live loads and
1,200 psf for axial compression dead loads plus sustained and transient live
loads. The Entrance Works Basin strip/spread footings may be founded at elevation
2 feet MSL (depth of about eight feet below the final grade surface of approxi -
mately elevation +10 feet MSL) . The Entrance Works Basin strip/spread footing
foundations should be designed by using a maximum allowable gross bearing pressure
of 1.600 psf for axial compression dead loads plus sustained live loads and 2.400
psf for axial compression dead loads plus sustained and transient live loads.
The Entrance Works Grit Chambers may be founded on strip/spread footings bearing
at elevation -1 foot MSL (depth of about 11 feet below the final grade elevation
of +10 feet MSL) . The footings should be designed by using a maximum allowable
gross bearing pressure of 1.600 psf for axial compression dead loads plus sus-
tained live loads and 2,400 psf for axial compression dead loads plus sustained
and transient live loads.
With the above-recommended maximum allowable gross bearing pressures being used
for design:
the factor of safety against an Entrance Works slab and strip/spread footing
foundation bearing failure is at least 3.0 for axial compression dead loads plus
sustained live loads.
the factor of safety against an Entrance Works slab and strip/spread footing
foundation bearing failure is at least 2.0 for axial compression dead loads plus
sustained and transient live loads.
the maximum total settlement of the Entrance Works Basin slab foundation should
be about 1.3 inches,
the maximum total settlement of the Entrance Works Basin strip/spread footings
should be 1.4 inches,
11 the maximum total settlement of the Entrance Works Grit Chamber strip/spread
footing foundations should be about 1.6 inches. and
the Entrance Works maximum angular distortion (differential settlement between
two points on the slab/footing foundations divided by the distance between the
two points on the slab/footing foundations) should be 1/510 (0.20 percent) .
It is expected that the ratio of elastic and consolidation settlement and the rate
of settlement of the Entrance Works slab/footing foundations will be as described
above for the Treatment Module.
Foundation Design - Office Building
Belled drilled piers and grade beams may be used to support the proposed Office
vii
4xc.
onsultonts
EXECUTIVE SUMMARY (Continued)
Building columns and walls. Shallow spread footing and continuous footing
foundations should not be used for support of the proposed Office Building because
of the presence of miscellaneous fill at the site and the high to very high
shrink/swell potential of the site surficial clays. The Office Building floor
should consist of a slab-on-grade floor with site preparation completed as de-
scribed above, or alternatively, a structural floor slab (suspended floor slab)
may be used. Foundation recommendations pertaining to the proposed Office Build-
ing columns, grade beams and floor are provided below:
Columns
Columns may be founded on belled drilled piers which bear at a depth of 20 feet
below the existing ground surface at the time of this investigation . The
drilled piers should be designed for maximum allowable net bearing pressures of
3,000 psf for axial compression dead loads plus sustained live loads and 4.500
psf for axial compression dead loads plus sustained and transient live loads.
The center to center spacing of the drilled piers should be equal to a minimum
of three times the drilled pier bell diameter. The maximum bell -to-shaft diame-
ter ratio for drilled piers should be three.
Allowable shaft friction in compression and tension for the portions of the
drilled pier shafts below a depth of ten feet beneath the ground surface is 150
psf. The ultimate shaft friction which could be exerted against the drilled
pier shafts as a result of swelling soils is 300 psf.
Use of the above recommended allowable maximum net foundation bearing pressures
provides for:
o a factor of safety against a drilled pier bearing failure of at least 3 .0
under axial compression dead loads plus sustained live loads, and at least 2.0
under axial compression dead loads plus sustained and transient live loads,
and
o drilled pier maximum total settlements of about one inch.
Because of the presence of miscellaneous fill to a depth of at least ten feet at
the proposed Office Building site, it is likely that it will be necessary to
case the drilled pier shaft excavations during drilled pier construction.
Drilled piers should be belled in order to provide resistance against pullout
forces which may be exerted on the drilled pier shafts by swelling soils .
Because of the presence of low strength clays in the upper 15 feet of overbur-
den, caving of pier bells may occur during construction. The adverse effects of
pier bell caving can be limited by:
o the designer using a maximum bell -to-shaft diameter ratio of three,
o the designer minimizing pier bell diameters, and
o the construction contractor minimizing the time between the completion of bell
underreaming and concrete placement.
Grade Beams
Grade beams should be founded on drilled piers and extend at least 1.5 feet
below finished grade. Minimum four inch high carton forms (void boxes) should
be provided beneath the grade beams.

EXECUTIVE SUMMARY (Continued)
IIGround Level Floor Slab
The floor for the proposed Office Building may consist of a slab-on-grade floor
II with site preparation performed as described above, or alternatively, a struc-
tural floor slab (suspended floor slab) may be used. Cushion sand (leveling
sand) should not be placed at areas of the slab-on-grade floor. If a slab-on
II
grade floor is used, it is suggested that cushion sand (leveling sand) not be
placed at areas of the slab-on-grade floor. If cushion sand becomes wet, ero-
sion and/or settling of the sand may occur which can result in the formation of
voids beneath the floor and associated structural distress.
IAs an alternate, a structural floor slab (suspended floor slab) may be used.
If a structural floor slab is used, a minimum four inch high void space should
IIbe provided beneath the structural floor slab.
Earth Pressure Design Parameters for Design of Below Ground Structures
I
Below ground structures may be designed by using equivalent fluid pressures, earth
pressure coefficients and soil strength properties. Below ground structures at
the EDSTP expansion site may be designed by using the following values of weight
of equivalent fluid in pounds per cubic foot (pcf) , active earth pressure coeffi -
II cient (Ka) . passive earth pressure coefficient (Kp) . angle of internal friction in
degrees, cohesion in psf and average soil wet unit weight in pcf:

The weights of equivalent fluid shown above include hydrostatic forces but Co not
I include surcharge forces imposed by construction equipment or vehicular loadings.
Surcharge forces must be considered in order to compute maximum stresses for use
in the design of below ground structures.
IIThe weights of equivalent fluid for the passive case and the passive earth pres-
sure coefficients shown above do not include a safety factor. It is recommended
that for design purposes, a factor of safety of 2.0 be applied to the weights of
II equivalent fluid for the passive case and the passive earth pressure coefficients
provided above. With the use of a safety factor of 2.0, the weights of equivalent
fluid for the passive case will be 140 pcf for the site fill , 141 pcf for the site
I
clays and 176 pcf for the site sands, and the passive earth pressure coefficients
will be 1.1 for the site fill . 1.4 for the site clays and 1.8 for the site sands.
Temporary Shoring and Bracing Requirements for Excavations
II It is recommended that excavations with vertical faces be limited to depths of
four feet or less. If Title 29, Part 1926. Section 1, Subpart P of the July 31,
1991 Code of Federal Regulations is used for temporary excavation shoring/bracing
I design, the overburden soils should be categorized as Type C soil . The definition
of Type C soil is provided in Appendix A of the above-referenced July 31, 1991
Code of Federal Regulations.

1.2 Description of Existing Conditions and Proposed Facilities
1.2.1 Existing Conditions
The existing EDSTP site facilities are shown in Figure 2 and consist
primarily of a treatment unit, a digester, a blower building, a lift
station, two sludge drying beds, one story buildings, access drives and
associated facilities. The ground surface elevation at the proposed
expansion site predominantly lies between about elevations +5 feet Mean
Sea Level (MSL) and +10 feet MSL. The land surface at the proposed
expansion site is covered with low maintained grasses. An existing
chain link fence is located at the proposed Treatment Module and Office
Building sites. A ditch varying in depth from about three feet to four
feet (flow line elevation of about +4 feet MSL to +5 feet MSL) is locat-
ed at the proposed Office Building site.
1.2.2 Proposed Facilities
The proposed expansion facilities are shown in Figure 2 and are de-
scribed below. The proposed expansion facilities dimensions/elevations
provided below are approximate only and are based upon preliminary
design drawings. The facility preliminary designs addressed in this
report are subject to revision based upon final design considerations.
Treatment Module
A 60 foot to 120 foot wide. 130 foot to 220 foot long, 18 foot high
reinforced concrete Treatment Module is to be constructed at the
northwest side of the existing site. The elevation of the existing
ground surface at the proposed Treatment Module site varies between
about elevation +6 feet MSL and elevation +10 feet MSL. An existing
asphalt paved parking area exists at the northwest side of the pro-
posed Treatment Module site as shown in Figure 2 . The Treatment
Module will be constructed immediately adjacent to the west side of
HTS, INC.

II the existing Clarifier/Aerator as shown in Figure 2.
The Treatment Module is to be founded on a slab foundation bearing at
about elevation -1 foot MSL (i .e. , sidewall top elevation of about +17
feet MSL) . Construction of the Treatment Module slab foundation at
elevation -1 foot MSL will require the excavation of seven to 11 feet
of existing overburden soil . The embedment depth of the Treatment
Module slab will be about nine feet below the existing average site
grade elevation of approximately +8 feet MSL. Construction of the
Treatment Module is to require the removal of the existing chain link
fence and asphalt paved parking area at the Treatment Module site.
Digester
A 55 foot wide. 75 foot long, 18 foot high reinforced concrete Diges-
ter is to be constructed at the east central side of the proposed
EDSTP expansion site. The proposed Digester site is located in an
1 open area with low maintained grass. The surface elevation of the
existing site ground surface at the proposed Digester site is about
elevation +7 feet MSL. The Digester is to be founded on a slab foun-
dation bearing at about elevation -4 feet MSL (i .e. , sidewall top
elevation of about +14 feet MSL) , with about 11 feet of embedment
below the existing site grade elevation of +7 feet MSL.
Entrance Works
A 20 to 48 foot wide. 20 foot to 60 foot long. 12 to 21 foot high
reinforced concrete Entrance Works is to be constructed at the south-
western portion of the proposed EDSTP expansion site. The Entrance
Works is to consist of an Entrance Works Basin and two Entrance Works
Grit Chambers as shown in Figure 2 . The Entrance Works is to be
constructed in an open area with low maintained grass. The existing
ground surface elevation at the proposed Entrance Works site is about
elevation +8 feet MSL.
The Entrance Works Basin is to be about 12 feet high and founded on a
combination of slab and strip/spread footing foundations. The Entrance
Works Basin slab foundation is to bear at about elevation +8 feet MSL
with about two feet of embedment below the final grade elevation of
about +10 feet MSL. The Entrance Works Basin footing foundations are
to bear near elevation +2 feet MSL with about eight feet of embedment
below the final grade elevation of about +10 feet MSL. Construction
of the Entrance Works Basin slab will require the removal of existing
fill to a depth of about seven feet (near elevation +1 foot MSL) and
the placement/compaction of select fill to about elevation +8 feet
MSL. Construction of the Entrance Works Basin footings will require
the removal of existing fill material down to natural in situ soil at
a depth of about seven feet (near elevation +1 foot MSL) and the
placement/compaction of select fill to about elevation +2 feet MSL.
The Grit Chambers are to be about 21 feet high and founded on footing
foundations which are to bear near elevation -1 foot MSL with about 11
feet of embedment below the final site grade elevation of approximate-
ly +10 feet MSL. Construction of the Entrance Works Grit Chambers
will require the removal of about nine feet of existing overburden
soil .
Office Building
A 35 foot wide. 55 foot long, single story Office Building is to be
HTS, isc.
Consultants
constructed at the southwest side of the proposed EDSTP expansion
site. The ground surface elevation at the proposed Office Building
site lies near elevation +8 feet MSL. A three to four foot deep ditch
is located at a portion of the proposed Office Building site as shown
in Figure 2. The flow line elevation of the existing ditch is about
elevation +4 to +5 feet MSL. The Office Building site is located at
an area where refuse/fill has been placed. Construction of the Office
Building will require the removal of a portion of the existing chain
link fence. The Office Building is to consist of a steel frame struc-
ture with a floor elevation near the final site grade elevation of
about +10 feet MSL.
The following foundation loadings were assumed for the proposed
expansion facilities for foundation design purposes:
Treatment Module slab and Digester slab gross bearing pressures were
assumed to be 1,400 pounds per square foot (psf) for axial compression
dead loads plus sustained live loads and 2. 100 psf for axial compres-
sion dead loads plus sustained and transient live loads.
Entrance Works slab foundation and footing foundation gross bearing
pressures were assumed to be:
800 psf for axial compression dead loads plus sustained live loads
and 1.200 psf for axial compression lead loads plus sustained and
transient live loads for the Entrance Works Basin slab foundation.
and
1,600 psf for axial compression dead loads plus sustained live loads
and 2,400 psf for axial compression dead loads plus sustained and
transient live loads for the Entrance Works Basin and Entrance Works
Grit Chamber footing foundations.
i Office Building loadings were assumed to be:
80 kips per column for axial compression dead loads plus sustained
live loads and 120 kips per column for axial compression dead loads
plus sustained and transient live loads.
approximately 1,000 pounds per linear foot for wall loadings, and
approximately 50 psf for floor loadings.
Gross foundation bearing pressure as referenced above is defined as the
contact pressure at the base of the slab foundation or footing founda-
tion due to the dead weight of the structure and sustained and transient
live loads associated with the structure.

establishing site drainage and installing storm water drain-
age structures if required,
excavating the overburden soils to depths of about seven feet
in order to provide for the removal of an approximately six
to seven foot thick fill layer as shown in Figure 3 and as
necessary to achieve the desired foundation slab grade eleva-

is placing/compacting select fill as described for the Treatment
Module in Section 1.4.1.1 above and as necessary to achieve
the desired slab or footing foundation elevations, and
constructing a four inch thick concrete mud mat over the
foundation subgrade soil in order to serve as a working
surface during foundation slab construction and to protect
the subgrade soils from drying/disturbance.
Backfill around the Entrance Works walls should consist of
materials placed/compacted as described for the Treatment
Module walls in Section 1.4.1.1 above.
1.4.1.4 Site Preparation - Office Building
These recommendations pertain to the area of the proposed
Office Building. The shrink/swell potential of the site surfi -
cial active clays may be mitigated by the use of site prepara-
tion techniques as described below, or alternatively, a struc-
tural floor slab (suspended floor slab) may be used. Mitiga-
tion of the shrink/swell potential of the active clays by using
site preparation techniques will require the placement/compac-
tion of inactive select fill to a minimum 4.5 foot thickness at
the floor slab areas of the proposed Office Building.
If the designer chooses to mitigate the high shrink/swell
potential of the site soils by excavation/fill placement, it is
recommended that site preparation be performed by:
e removing the chain link fence and removing the Layer I fill
at the site (Layer I fill at the proposed Office Building
site is expected to extend to a depth of about ten feet) .
t excavating the overburden soils to depths as necessary to
achieve final grade.
proofrolling the exposed in situ soils with a 15 ton roller.
observing the soils during proofrolling to detect any wet.
soft or pumping soils and treating wet, soft or pumping soils
with suitable drying or stabilizing agents or removing the
unsuitable soils and placing/compacting select fill or suit-
able earth fill .
compacting the exposed in situ soils to an in-place dry
density equal to at least 95 percent of the maximum standard
dry density (ASTM D 698) at a moisture content within ± 2
percent of the optimum moisture content.
placing/compacting suitable earth fill or select fill as
necessary to an elevation about 4.5 feet below the bottom
elevation of the slab-on-grade floor, and
placing/compacting imported select fill to a minimum thick-
ness of 4.5 feet below the slab-on-grade floor base eleva-
tion.
Suitable earth fill or select fill properties and select fill
placement/compaction should be as described for the Treatment
Module above in Section 1.4.1.1.
HTS,Ice
ronsutramsJ
11-
Use of the site preparation technique as described above.
should limit the maximum PVR of the soils beneath slab-on-grade
floors to about one inch.
As an alternate, a structural floor slab (suspended floor slab)
may be used to mitigate the site soil shrink/swell potential .
If a structural floor slab is used, site preparation at the
Office Building site should be performed by:
removing the upper six inches of site fill material , and
establishing site drainage and installing storm drainage
structures if required.
The surficial clay excavated at the site will not be suitable
for use as select fill at the proposed Office Building area.
The construction contractor may encounter difficulty in densi -
fying/preparing the surficial clays depending upon weather
conditions and should be prepared to adequately dry/stabilize
any unstable surficial soils as described for the Treatment
Module in Section 1.4.1.1 above.
Backfill around the building walls should consist of materials
placed/compacted as described for the Treatment Module walls in
Section 1.4.1.1 above.
1.4.2 Recommended Foundation Types and Allowable Loadings
Recommended foundation types and loadings for the proposed structures
are provided below.
1.4.2.1 Foundation Design - Treatment Module
The proposed Treatment Module will be constructed immediately
adjacent to the existing Clarifier/Aerator . Care should be
taken to assure that the excavation for the proposed Treatment
Module is not carried to significant depths below the existing
Clarifier/Aerator foundation unless adequate bracing/underpin-
ning is provided. The Treatment Module may be supported on a
reinforced concrete slab founded at about elevation -1 foot
MSL. The slab should be designed using a maximum allowable
gross bearing pressure of 1,400 psf for axial compression dead
loads plus sustained live loads and 2.100 psf for axial corn-
pression dead loads plus sustained and transient live loads.
With the above-recommended maximum allowable gross bearing
pressures being used for design:
the factor of safety against an Treatment Module slab founda-
tion bearing failure is at least 3.0 for axial compression
dead loads plus sustained live loads, and at least 2.0 for
axial compression dead loads plus sustained and transient
live loads,
the Treatment Module slab foundation maximum total settle-
ments should be about 1.3 inches at the center point of the
slab and 0.5 inches at the corner of the slab as shown in

tion (differential settlement between two points on the slab
divided by the distance between the two points on the slab)
Ishould be about 1/1,184 (0.08 percent) as shown in Table 2.
The estimated maximum angular distortion of 1/1. 184 (0 .08
percent) compares favorably with a suggested maximum angular
I distortion of 1/200 (0.5 percent) as shown in Table 2.
About 30 percent of the total settlement of the Treatment
Module slab foundation is expected to be immediate (elastic)
settlement and the remaining 70 percent of the settlement is
expected to be long term (consolidation) settlement. It is
expected that the long term settlement of the Treatment Module
slab foundation will occur over a period of about 14 monthsI
with the Treatment Module fully loaded. The accuracy of the
time rate of settlement estimate is approximate only because
the number and sequencing of sand/silt partings , seams or
layers and the continuity of the partings, seams or layers will
significantly influence the time over which long term settle-
Iments occur.
Treatment Module piping connections should be designed to
I
accommodate the expected Treatment Module settlements. Treat-
ment Module piping hookups should be made subsequent to the
dissipation of the elastic settlement.
I If the estimated settlements and angular distortions provided
above are deemed to be excessive by the designer, the Treatment
Module settlements may be reduced by preloading the slab foun-
I dation area with a soil preload or by using an alternative
foundation system.
I
Site preparation of the subgrade soils and backfill placement
for the Treatment Module slab should be performed as described
in Section 1.4.1.1 above.
I 1.4.2.2 Foundation Design - Digester
The Digester may be supported on a reinforced concrete slab
founded at elevation -4 feet MSL (depth of about 11 feet below
I the existing ground surface) . The foundation slab should be
designed using a maximum allowable gross bearing pressure of
1.400 psf for axial compression dead loads plus sustained live
I
loads and 2. 100 psf for axial compression dead loads plus
sustained and transient live loads.
With the above-recommended maximum allowable gross bearing
Ipressures being used for design:
the factor of safety against a Digester slab foundation
I bearing failure is at least 3.0 for axial compression dead
loads plus sustained live loads, and at least 2.0 for axial
compression dead loads plus sustained and transient live
Iloads.

be about 0.2 inches at the center point of the slab and 0.1
inches at the corner of the slab as shown in Table 2. and
e the Digester slab foundation maximum angular distortion
differential settlement between two points on the slab
divided by the distance between the two points on the slab)
should be about 1/3.985 (0.03 percent) as shown in Table 2.
The estimated maximum angular distortion of 1/3 .985 (0 .03
percent) compares favorably with a suggested maximum angular
distortion of 1/200 (0.5 percent) as shown in Table 2.
About 30 percent of the total settlement of the Digester slab
foundation is expected to be immediate (elastic) settlement and
the remaining 70 percent of the settlement is expected to be
long term (consolidation) settlement. It is expected that the
long term settlement of the Digester slab foundation will be as
described above for the Treatment Module in Section 1.4.2.1.
Digester piping connections should be designed to accommodate
the expected Digester settlements . Digester piping hookups
should be made subsequent to the dissipation of the elastic
settlement.
Site preparation of the subgrade soils and backfill placement
for the Digester slab should be performed as described in
Section 1.4.1.2 above.
1.4.2.3 Foundation Design - Entrance Works
The Entrance Works may be supported on a combination of
reinforced concrete slab and footing foundations as described
below.
The Entrance Works Basin may be founded on a reinforced con-
crete slab or strip/spread footings. The Entrance Works Basin
slab foundation may be founded at elevation +8 feet MSL. The
slab foundation should be designed by using a maximum allowable
gross bearing pressure of 800 psf for axial compression dead
loads plus sustained live loads and 1,200 psf for axial com-
pression dead loads plus sustained and transient live loads.
The Entrance Works Basin strip/spread footings may be founded
at elevation +2 feet MSL (depth of about eight feet below the
final grade surface of approximately elevation +10 feet MSL) .
The Entrance Works Basin strip/spread footing foundations
should be designed by using a maximum allowable gross bearing
pressure of 1.600 psf for axial compression dead loads plus
sustained live loads and 2.400 psf for axial compression dead
loads plus sustained and transient live loads.
The Entrance Works Grit Chambers may be founded on strip/spread
footings bearing at elevation -1 foot MSL (depth of about 11
feet below the final grade elevation of +10 feet MSL) . The
footings should be designed by using a maximum allowable gross
bearing pressure of 1.600 psf for axial compression dead loads
t
plus sustained live loads and 2.400 psf for axial compression
dead loads plus sustained and transient live loads.

1.4.2.4 Foundation Design - Office Building
Belled drilled piers and grade beams may be used to support the
proposed Office Building columns and walls. Shallow spread
footing and continuous footing foundations should not be used
for support of the proposed Office Building because of the
presence of miscellaneous fill at the site and the high to very
high shrink/swell potential of the site surficial clays. The
Office Building floor should consist of a slab-on-grade floor
