SCOPE OF SERVICES
The following scope of services for these projects is based on 1) frequencies and test type
specified in the project specifications, and 2) our recommendations for alternate frequency and
test types. These recommendations may or may not reflect specific City of Redding interests or
desires.
Our plan to developing an appropriate level of testing is based on our understanding of the
construction, information presented in the plans and specifications, and our perception of the
City's needs. Kleinfelder is committed to providing quality service to it's clients, commensurate
with their wants, needs and desired level of risk. If a portion of this proposal does not meet your
specific needs, or if those needs have changed, Kleinfelder stands ready to consider appropriate
modifications, subject to the standards of care to which we adhere as professionals.
OFF-SITE STREET AND UTILITIES
The project will involve construction of approximately 1.8 miles of new asphalt concrete roadway
at Abernathy Lane, Viking Way, and overlay existing asphalt concrete on Tarmac Road.
Appurtenant construction will include storm drainage, water, sewer, and associated utilities.
Based on our review of the project plans prepared by Sharrah, Dunlap, Sawyer, Civil Engineers;
verbal schedules provided by the general contractor and subcontractors; and discussions with Mr.
Eugene Law of Harris Associates, and Mr. Rick Pizzi, Construction Manager for City of
Redding, we anticipate providing the following services:
EARTHWORK
As required by the project specifications, testing and inspection of excavations, backfilling, filling,
and compacting shall be performed as follows:
Mass Grading
Foundation embankment under structures and pipelines, top two feet of road
subgrade, and 10-foot wide backfill zone around structures for each one foot of
vertical embankment or backfill height, conduct one test every 300 square feet.
Other embankment same as above except substitute 600 for 300.
As indicated by the contractor, Jaxon Baker, mass grading will require approximately 5 working
days to complete. Approximately 14,000 cubic yards of material will be placed. We anticipate a
maximum of approximately 3,500 cubic yards of fill will be placed on a daily basis. During this
time we would provide a technician to perform a minimum of one nuclear density test for every
11 cubic yards of fill placed as required by the project specifications. Based on these production
estimates we estimate approximately 30 man hours per day will be required to adequately
determine fill composition as required by the project specifications.
We feel this frequency of testing as described in the project specifications is excessive. Based on
our experience we feel that a minimum of one test for every 100 cubic yards of fill placed would
be adequate to determine the composition of fill compaction. Based on this frequency we would
provide a technician to perform a minimum of one density test for every 100 cubic yards of fill
placed.
For this production rate we estimate approximately 4 man hours per day will be required to
adequately determine fill composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during mass grading as follows:
AASHTO T-180 - we anticipate performing approximately 2 moisture density
curves and 1 to 2 check points during the course of mass grading.
Off-Site Subgrade
The project specifications indicated test frequency as described under mass grading. Since in our
opinion this requirement is excessive, we have prepared alternate test type and frequency
recommendations.
• e
As indicated by the contractor, Jaxon Baker, off-site subgrade preparation will require
approximately 4 working days to complete. During this time we would provide a technician to
perform a minimum of one nuclear density test for every 2,700 square feet of subgrade area.
We propose approximately 2 man hours per day will be required to adequately test subgrade
composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during site subgrade construction as follows:
AASHTO T-180 - we anticipate performing approximately 1 to 2 moisture density
curves and 1 to 2 check points during the course of site subgrade construction.
Testing of subgrade soils for R-value is not listed as a requirement by the City. We would
recommend R-value testing be performed to assure a proper structural section is achieved. We
would provide a qualified soils engineer to visually classify and assess subgrade soils and
recommend the number of R-value tests required.
We estimate approximately 1 to 2 R-value tests would be performed.
Underground Utilities
It is our understanding that a portion of this work has already been given to MTI Testing. We
have prepared estimates for this work assuming the remainder of work is to be awarded in this
proposal. If this work will not be awarded in this proposal, please disregard this section.
As indicated by the contractor, Jaxon Baker, underground utility backfill will require
approximately 20 working days to complete. During this time we would provide a technician to
perform a minimum of one nuclear density test for every 300 square feet and one foot of vertical
backfill as required by the project specifications.
We anticipate approximately 2 man hours each day that utilities are backfilled will be required to
adequately determine backfill composition.
0 •
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during underground utility backfill as follows:
AASHTO T-180 - we anticipate performing approximately 2 to 3 moisture density
curves during the course of underground utility backfill.
CONCRETE
Cast-In-Place Concrete
It is our understanding that a portion of this work has already been given to MTI Testing. We
have prepared estimates for this work assuming the remainder of work is to be awarded in this
proposal. If this work will not be awarded in this proposal, please disregard this section.
Concrete mix designs will be reviewed for compliance with applicable UBC requirements and
project specifications. Concrete tests and inspections will be performed in accordance with the
project specifications as follows:
Slump tests shall be performed for every mixer at the beginning and near the end
of the load to calibrate the mixing capabilities
A set of 4 (minimum) compressive strength test specimens shall be prepared for
each location (slab, wall, column, beam, etc.) for each days pour or every 50 cubic
yards whichever is greater;
Air content shall be determined once for each mix design;
As indicated by the contractor, Jaxon Baker, cast-in-place concrete will require approximately 10
more working days to complete. Approximately 30 yards of concrete will be placed per day.
During this time we would provide a technician to sample and test concrete.
In accordance with the above schedule and project specifications we would provide an ICBO
Certified Special Inspector for approximately 1 hour for each day concrete is poured. We
anticipate sampling concrete and preparing and testing 1 set of 4 compressive strength cylinders
(4 test specimens) each day concrete is poured.
0 •
Concrete cylinder samples will be stored on-site in a temperature controlled environment for the
initial 24 hour cure, and then picked up the following day at no additional cost if we are on-site.
Project specifications require a certificate indicating composition, quality, size and weight of
each aggregate, amount of cement, water, and other constituents is required for each load of
concrete. This information is usually supplied by the ready mix supplier, not the testing agency.
We will collect batch weight tickets for each load of concrete delivered to the site. If full-time
batch plant inspection is required, we can provide this service.
In accordance with the above schedule we would provide an ICBO Certified Special Inspector
for approximately 3 hours each day concrete is poured to perform batch inspection should it be
required.
ASPHALT CONCRETE PAVING/AGGREGATE BASEROCK
Aggregate Baserock
Aggregate baserock will be tested in accordance with the project specifications as follows:
Comply with the requirements of State of California, Business and Transportation
Agency, Department of Transportation's Standard Specifications.
These requirements include:
Grading (sieve analysis); and
Compaction;
As indicated by the contractor, Jaxon Baker, aggregate base placement and compaction will
begin approximately May 1 and will continue for approximately 20 working days. During this
time we would provide a qualified technician to sample and test as described above.
In accordance with the above schedule and project specifications we anticipate providing the
technician to perform density tests approximately 2 hours per day for approximately 6 days.
• •
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate materials during construction as follows:
AASHTO T-180 or Cal 216 - we anticipate performing 2 laboratory curves during
construction;
Cal 202 and 217 - we anticipate performing one sieve analysis and one sand
equivalent unless aggregate base material changes.
Asphalt Concrete Paving
Asphalt Concrete Paving will be tested and inspected in accordance with the project
specifications as follows:
Comply with the requirements of State of California, Business and Transportation
Agency, Department of Transportation's Standard Specifications.
These requirements include:
Grading (sieve analysis);
Aggregate quality (S.E., L.A. rattler, etc);
Asphalt concrete mixture quality (marshall stability);
Temperature;
Thickness; and,
Spreading and compacting;
As indicated by the contractor, Jaxon Baker, asphalt concrete paving will begin approximately
June 1 and will continue for approximately 10 working days. According to the California
Standard Specifications placement of asphalt concrete paving shall be performed in accordance
with their method(s). Density testing is not required as placement and compaction is to be
completed by method. Control of temperature and thickness is required, however. During this
•
time we would provide a qualified technician to observe placing and compacting operations, and
monitor mix temperatures as described above.
In accordance with the above schedule and project specifications, we anticipate providing the
technician to measure thickness, perform temperature tests and monitor the contractors
operations approximately 8 hour per day for approximately 8 days.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate materials during construction as follows:
Marshall Maximum Density - we anticipate performing 2 Marshall Max Densities
during construction;
Cal 216 and 202 - we anticipate performing two each sieve analysis and sand
equivalent during construction.
Note: This function may be performed by City staff or Harris & Associates.
As an alternate to the that specified above we propose the following tests and inspections be
performed:
Extractions and sieve analysis on asphalt mix during placement to assure mix
quality - we recommend 2 sets of these tests.
Laboratory and field testing to assure proper materials and density - we
recommend that the Marshall maximum density be performed. Field testing
consisting of nuclear density testing at a frequency of approximately one test per
8,000 square feet each lift.
We anticipate providing a technician to perform field density tests, sample, and observe
approximately 2 to 4 hours per day for approximately 8 days.

CORPORATION YARD
The project will involve construction of a single-story metal building with a concrete slab-on-
grade floor. The proposed building will encompass approximately 128,500 square feet in plan
area; total site area will encompass approximately 17.9 acres. Appurtenant construction will
include asphalt concrete paving, concrete masonry partitioning, concrete slabs, underground
utilities, and landscaping.
Based on our review of the project plans prepared by Dreyfuss & Blackford Architects in
conjunction with Nichols, Melberg, & Rossetto, Architects and Sharrah, Dunlap, Sawyer Civil
Engineers; verbal schedules provided by the general contractor and subcontractors; and
discussions with Mr. Eugene Law of Harris Associates, and Mr. Rick Pizzi, Construction
Manager for City of Redding, we anticipate providing the following services:
EARTHWORK
Mass Grading/Building Pads/Site Grading and Subgrade/Underground Utilities Backfill
As required by the project specifications, testing and inspection of excavations, backfilling, filling,
and compacting shall be under the direction of a soils engineer. No frequency of testing is
specified for this item; therefore, we propose testing be performed at the following frequencies:
Mass Grading
As indicated by the subcontractor, Northstate Constructors, mass grading will require
approximately 18 working days to complete. Approximately 86,000 cubicyards of material will
be placed. We anticipate a maximum of approximately 4,500 cubic yards of fill will be placed on
a daily basis.
During this time we would provide a technician to perform a minimum of one nuclear density
test for every 100 cubic yards of fill placed. Based on these production estimates we estimate
approximately 8 man hours per day will be required to adequately determine fill composition.
e •
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during mass grading as follows:
AASHTO T-180 - we anticipate performing approximately 3 moisture density
curves and 1 to 2 check points during the course of mass grading.
Building Pads
As indicated by the subcontractor, Northstate Constructors, building pad fills and subgrade
preparation will require approximately 15 working days to complete. During this time we would
provide a technician to perform a minimum of one nuclear density test for every 100 cubic yards
of fill placed and one density test for every 2,700 square feet of subgrade area.
We anticipate approximately 4 man hours per day will be required to adequately determine fill
composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during building pad construction as follows:
AASHTO T-180 - We anticipate performing approximately 1 to 2 moisture density
curves and 1 to 2 check points during the course of building pad construction.
Site Grading and Subgrade
As indicated by the subcontractor, Northstate Constructors, site grading and subgrade
preparation will require approximately 10 working days to complete. During this time we would
provide a technician to perform a minimum of one nuclear density test for every 100 cubic yards
of fill placed and one density test for every 2,700 square feet of subgrade area.
We anticipate approximately 4 man hours per day will be required to adequately determine fill
composition.
• •
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during site grading as follows:
AASHTO T-180 - We anticipate performing approximately 1 to 2 moisture density
curves and 1 to 2 check points during the course of site grading construction.
Testing of subgrade soils for R-value is not listed as a requirement by the City. We would
recommend R-value testing be performed to assure a proper structural section is achieved. We
would provide a qualified engineer to classify and evaluate subgrade soils to determine the
number of R-value tests required.
We estimate approximately 1 to 2 hours of engineering time to assess the soil subgrade, and 1 to
2 R-value tests may be performed.
Underground Utilities
As indicated by the subcontractor, Northstate Constructors, underground utility backfill will
require approximately 24 working days to complete. During this time we would provide a
technician to perform a minimum of one nuclear density test for every 50 cubic yards of backfill
placed.
Since we anticipate this to occur concurrently with site grading activities, we anticipate
approximately 1 hour per day will be required to adequately determine fill composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during earthwork construction as follows:
AASHTO T-180 We anticipate performing approximately 4 moisture density
curves during the course of earthwork construction.
FOUNDATIONS
As required by the project specifications testing and inspections of drilled pier foundations is
required. Determination by the Soils Engineer of elevations, drill lengths, and bearing will be
required during excavations. Assessment of the bearing conditions for perimeter and/or spread
footing excavations were not mentioned in the project specifications. We feel, however that
observation of the perimeter/spread footings should be included.
Drilled Piers
As required by the project specifications, testing for bearing capacity shall be made at drilled
pier locations at the frequency requested. Undisturbed soil samples will be taken 8'-0" below the
bottom of piers bearing on hardpan for the first 3 piers and then as directed by the Architect.
For piers bearing on rock the required frequency is the first 3 piers then every 6 thereafter.
Undisturbed samples shall be tested for:
Unconfined compression;
Moisture content; and,
Density;
To accomplish what has been specified will require use of a drill rig equipped for soil sampling.
To facilitate this process we would attempt to obtain samples from a grid system based on the
actual pier foundation locations. These borings would be made prior to construction to avoid
delaying the contractor's schedule.
We estimate a cost of approximately $400 to $450 per location to drill and test as requested in
the specifications.
As an alternate we propose the drilled pier excavations be observed by the Soils Engineer after
drilling but prior to placing reinforcing steel. Based on the number of pier excavations and the
schedule provided by Sacramento Drilling, the subcontractor, we estimate approximately 5 site
visits of 2 hour duration by the Soils Engineer. We estimate our fee for this would be $850.00.
Perimeter/Spread Footings
Observation of spread/perimeter footing excavations was not addressed in the project
specifications. We feel, however, that in order to assure compliance with recommendations
presented in our Geotechnical Investigation Report, these excavations should be observed.
We recommend a qualified engineer observe the excavations prior to placement of forms or
reinforcement. At this time, based on available information, we have assumed that this
operation may occur concurrently with the excavation of drilled piers. We estimate 5 site visits of
2 hour duration by the Soils Engineer. We estimate our fee for this would be $850.00.
CONCRETE
Drilled Cast-In-Place Concrete Piers
Concrete tests and inspections will be performed in accordance with the project specifications as
follows:
Review concrete mix design;
Slump tests shall be performed for every load of concrete at the point of discharge;
Air content shall be determined for each set of compressive strength specimens;
Ambient air temperature will be measured each time a set of compressive strength
specimens is made; and,
Compressive strength tests shall be performed for every 50 cubic yards or fraction
thereof except when the total volume of any one grade of concrete exceeds 150
cubic yards per day then one test for every 150 cubic yards or fraction thereof shall
be performed.
Test data shall be provided to the Architect and Contractor on the same day the
tests were performed.
As indicated by the General Contractor, Clark and Sullivan and their subcontractor, Sacramento
Drilling, drilled piers will require approximately 5 working days to complete. In accordance with
the project specifications concrete for drilled cast-in-place piers shall be placed immediately
after approval of the excavations. During this time we would provide a technician to sample and
test concrete.
In accordance with the above schedule and project specifications we would review 1 mix design,
and provide an ICBO certified technician for approximately 2 hours for each day concrete is
poured. We estimate the technician would sample approximately 3 to 4 sets of 4 each
compressive strength cylinders each day.
Cast-In-Place Concrete
Prior to the placement of concrete, formwork, reinforcing steel, and embedded items will be
inspected. Concrete mix designs will be reviewed for compliance with applicable UBC
requirements and project specifications. Concrete tests and inspections will be performed in
accordance with the project specifications as follows:
Slump tests shall be performed for every load of concrete at the point of discharge
(first discharge from each truck will be slumped at beginning and end of load);
Air content shall be determined for each days pour on each type of air entrained
concrete;
Ambient temperature will be measured every hour when air temperature is below
40-deg. F. and above 80-deg. F., and each time a set of compressive strength
specimens is made; and
Compressive strength tests shall be performed for every 50 cubic yards or fraction
thereof or every 2000 square foot of surface area for slabs or walls or fraction

MATERIALS RECOVERY FACILITY
The project will involve construction of 5 single-story masonry and metal buildings with concrete
slab-on-grade floors. The proposed buildings will encompass approximately 74,300 square feet
in plan area; total site area will encompass approximately 24.1 acres. Appurtenant construction
will include, asphalt concrete paving, concrete slabs, underground utilities, and landscaping.
Metal building systems for this site will be contracted separately.
Based on our review of the project plans prepared by URS Consultants, project design firm, and
Sharrah, Dunlap, Sawyer, Civil Engineers; verbal schedules provided by the general contractor
and subcontractors; and discussions with Mr. Eugene Law of Harris Associates, and Mr. Rick
Pizzi, Construction Manager for City of Redding, we anticipate providing the following services:
EARTHWORK
Mass Grading/Building Pads/Site Grading and Subgrade/Underground Utilities
Backfill/Structure Backfill
As required by the project specifications, testing and inspection of excavations, backfilling, filling,
and compacting shall be performed as follows:
Mass Grading;
Foundation embankment under structures and pipelines, top two feet of road
subgrade, and 10 foot wide backfill zone around structures for each one foot of
vertical embankment or backfill height, conduct one test every 300 square feet.
Other embankment same as above except substitute 600 for 300.
As indicated by the subcontractor, N. & T. Digmore, mass grading will require approximately 25
working days to complete. Approximately 110,000 cubic yards of material will be placed. We
anticipate a maximum of approximately 4,500 to 5,000 cubic yards of fill will be placed on a daily
basis.
During this time we would provide a technician to perform a minimum of one nuclear density
test for every 11 cubic yards of fill placed as required by the project specifications. Based on
these production estimates we estimate approximately 64 man hours per day will be required to
adequately determine fill composition (as required by the project specifications).
We feel this frequency of testing as described in the project specifications is excessive. Based on
our experience we feel that a minimum of one test for every 100 cubic yards of fill placed would
be adequate to determine the composition of fill compaction. Based on this frequency we would
provide a technician to perform a minimum of one density test for every 100 cubic yards of fill
placed.
Based on the production rates given we estimate approximately 6 to 8 man hours per day during
mass grading will be required to adequately determine fill composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during mass grading as follows:
AASHTO T-180 - we anticipate performing approximately 3 moisture density
curves and 3 check points during the course of mass grading.
Building Pads
The project specifications indicated test frequency as described under mass grading. Since in our
opinion this requirement is excessive, we have prepared alternate test type and frequency
recommendations.
As indicated by the subcontractor, N. & T. Digmore, building pad fills and subgrade preparation
will require approximately 6 to 7 working days to complete. During this time we would provide a
technician to perform a minimum of one nuclear density test for every 100 cubic yards of fill
placed or for every 2,700 square feet of subgrade area.
We anticipate approximately 2 man hours per day will be required during building pad
construction to adequately determine fill composition.
® s
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during building pad construction as follows:
AASHTO T-180 - We anticipate performing approximately 1 to 2 moisture density
curves and 1 to 2 check points during the course of building pad construction.
Site Grading and Subgrade
The project specifications indicated test frequency as described under mass grading. Since in our
opinion this requirement is excessive, we have prepared alternate test type and frequency
recommendations.
As indicated by the subcontractor, N. & T. Digmore, site grading and subgrade preparation will
require approximately 10 working days to complete. During this time we would provide a
technician to perform a minimum of one nuclear density test for every 100 cubic feet of fill
placed and one density test for every 2,700 square feet of subgrade area.
We anticipate approximately 2 to 3 man hours per day will be required each day of site grading
and subgrade to adequately determine fill composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during site grading as follows:
AASHTO T-180 - We anticipate performing approximately 1 to 2 moisture density
curves and/or check points during the course of site grading construction.
Testing of subgrade soils for R-value is not listed as a requirement by the City. We would
recommend R-value testing be performed to assure a proper structural section is achieved. We
recommend that a qualified soils engineer classify and assess subgrade soils to determine the
number of R-value tests necessary.
We estimate approximately 1 to 2 hours of engineer time on-site to review the soil subgrade; we
estimate that 1 to 2 R-value tests would be performed.
Underground Utilities
As indicated by the subcontractor, N. & T. Digmore, underground utility backfill will require
approximately 30 working days to complete. During this time we would provide a technician to
perform a minimum of one nuclear density test for every 300 square feet and one foot of vertical
backfill placed. Additional man hours for this service would be minimal as utility backfill will be
performed concurrently with building pad fills and subgrade preparation as well as site grading.
For this service we estimate approximately 1 to 2 man hours per day will be required during
backfill operations.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during underground utility backfill as follows:
AASHTO T-180 - We anticipate performing approximately 1 to 2 moisture density
curves and possibly 1 to 2 check points during the course of utility backfill
construction.
Structure Backfill
We were unable to determine the contractors schedule for this activity as the general contractor
was unsure who would be performing this work. We estimate approximately 15 working days will
be required to complete the structure backfill. During this time we would provide a technician
to perform a minimum of one nuclear density test for every 300 square feet and one foot of
vertical backfill placed as required by the project specifications.
We anticipate approximately 2 man hours per day will be required to adequately determine fill
composition.
We anticipate a moderate program of laboratory testing would be required to adequately
evaluate soil materials during structure backfill construction as follows:
AASHTO T-180 - We anticipate performing approximately 5 moisture density
curves during the course of structure backfill construction.
FOUNDATIONS
Assessment of the bearing conditions for perimeter and/or spread footing excavations were not
mentioned in the project specifications. We feel, however that observation of the
perimeter/spread footings should be included.
Perimeter/Spread Footings
Observation of spread/perimeter footing excavations was not addressed in the project
specifications. We feel, however, that in order to assure compliance with recommendations
presented in our Geotechnical Investigation Report, these excavations should be observed.
We recommend a qualified engineer observe the excavations prior to placement of forms or
reinforcement. We estimate 8 site visits of 2 hour duration by the Soils Engineer. We estimate
our fee for this would be $1,360.00.
CONCRETE
Cast-In-Place Concrete
Concrete mix designs will be reviewed for compliance with applicable UBC requirements and
project specifications. Concrete tests and inspections will be performed in accordance with the
project specifications as follows:
Slump tests shall be performed for every mixer at the beginning and near the end
of the load to calibrate the mixing capabilities
A set of 4 (minimum) compressive strength test specimens shall be prepared for
each location (slab, wall, column, beam, etc.) for each days pour or every 50 cubic
yards whichever is greater;
Air content shall be determined once for each mix design;
As indicated by the subcontractor, Muse Concrete, cast-in-place concrete will require
approximately 60 to 70 working days to place. Approximately 150 to 200 cubic yards of concrete
0 0
will be placed per day. During this time we would provide a technician to sample and test
concrete.
In accordance with the above schedule and project specifications we would provide an ICBO
Certified Special Inspector for approximately 6 hours each day concrete is poured. The
technician would sample approximately 3 to 4 sets of compressive strength cylinders (4
specimens per set) each day.
We feel the frequency of testing for concrete as described in the project specifications is
incomplete. Therefore, we propose the following tests and inspections be performed during
concrete placement:
Slump tests will be performed for every load at the point of discharge;
Air content shall be determined for each days pour on each type of air entrained
concrete;
Ambient temperature will be measured every hour when air temperature is below
40-deg. F. and above 80-deg. F., and each time a set of compressive strength
specimens is made; and,
Compressive strength tests shall be performed for every 50 cubic yards or fraction
thereof for each days placement;
Test data shall be provided to the Architect and Contractor in writing within 24
hours of testing.
As indicated by the subcontractor, Muse Concrete, cast-in-place concrete will require
approximately 60 to 70 working days to place. Approximately 150 to 200 cubic yards of concrete
will be placed per day. During this time we would provide a technician to sample and test
concrete. In accordance with the above schedule and project specifications we would provide an
ICBO Certified Special Inspector for approximately 6 to 8 hours for each day concrete is poured.
Based on the above schedule and quantity of concrete, the technician would sample
approximately 3 to 4 sets of 4 each compressive strength cylinders each day.
Concrete cylinder samples will be stored on-site in a temperature controlled environment for the
initial 24 hour cure, and then picked up the following day at no additional cost if we are on-site.
Project specifications require a certificate indicating composition, quality, size and weight of
each aggregate, amount of cement, water, and other constituents is required for each load of
concrete. This information is usually supplied by the ready mix supplier, not the testing agency.
We will collect batch weight tickets for each load of concrete delivered to the site. If full-time
batch plant inspection is required, we can provide this service.
In accordance with the above schedule we would provide an ICBO Certified Special Inspector
for approximately 6 to 8 hours each day concrete is poured to perform batch plant inspection
should it be required.

approximately May 30 and will continue for approximately 25 working days. During this time we
would provide an ICBO Certified Special Inspector to sample and test as described above.
In accordance with the above schedule and project specifications we anticipate providing the
technician for approximately 1 to 2 hours each day that composite masonry prisms are prepared.
We anticipate sampling approximately 2 to 3 sets of 3 each masonry prisms during construction.
The testing and inspection requirements listed above and in the project specification indicate
that the City of Redding intends to perform their own inspection during masonry lay up. If it is
determined that special inspection is required, Kleinfelder could perform this task. During this
time we would provide an ICBO Certified Special Inspector to sample and test as described
above as well as inspect masonry construction as follows:

Pizzi, Construction Manager for City of Redding, we anticipate providing the following services:
STRUCTURAL STEEL
Shop Fabrication Inspection
Fabrication inspection is indicated in the project specifications to be performed for visual
welding, high strength bolting, mill certification review, and non-destructive testing of full
penetration welds greater than 3/8 inch. It is our understanding that the fabrication will be
performed in an ICBO approved fabricators shop. According to the UBC welding performed in
an approved shop does not require special inspection. If the City chooses to require this service
Kleinfelder would be able to perform the tests and inspections mobilizing from our Reno office.
We anticipate fabrication will be completed within the 35 working day schedule as supplied to us
from American Building Manufacturer located in Carson City, Nevada. During fabrication we
would provide an AWS Certified Welding Inspector as requested.
