Subject: Proposal — Geotechnical and Structural Design Services — George Brett
Field Scoreboard Foundation, City of El Segundo, California
Dear Mr. Sassoon:
GMU Geotechnical, Inc (GMU) is pleased to submit this proposal to provide geotechnical and
structural design services for confirmation of existing scoreboard foundation dimensions and
embedment and additional structural design services related to the connection of a proposed new
scoreboard to the existing scoreboard foundations at George Brett Field.
Connection to and utilization of existing scoreboard foundations will be possible provided the
footings meet minimum foundation requirements per our analysis. Foundation internal strength with
respect to amount and size of reinforcement, (if any) and strength of concrete will not be inspected
or reported in any way per our scope of work outlined below.
We proposed to perform the following scope of work:
Task 1— Geotechnical Investigation
Geotechnical Site ]nvesti gatioii
• Perform a site visit to mark the location of our planned subsurface exploration. As
required by law, we will notify Underground Service Alert (USA) of the proposed
exploration location prior to exploratory excavation.
• Explore the site by performing one (1) hand -excavated test -pit to a maximum depth
of 8-feet below the existing grade at the proposed location of the scoreboard.
• Confirm scoreboard footing diameter and embedment in relation to the lowest
adjacent grade. Confirm connection type between the existing steel W-Section
columns and concrete footings. Confirm surface grading at foundation location.
• Collect bulk and relatively undisturbed soil samples for geotechnical laboratory
testing.

PROPOSAL: Geotechnical and Structural Design Services, George Brett Field Scoreboard Foundation, City of El
Segundo, CA
Task 2 — Geotechnical Laboratory Testing
l�alaor'ator° "1"csti.n
• Perform laboratory testing to evaluate various engineering properties of the sub-
surface materials. Laboratory testing will likely consist of in -place moisture and
density, soil classification, direct shear testing, and corrosion testing.
Task 3 — Geotechnical Engineering Analysis and Structural Design Services
Geotechnical Engincerimmrm7 Anal scs / Desi" ii Letter Preoaratioji
• Analyze laboratory testing results to determine the sites deep foundation design
parameters such as axial capacity, (end bearing and skin -friction), lateral capacity,
and minimum required CIDH caisson diameter and embedment.
• Provide a geotechnical design parameters letter with laboratory testing results and
drill hole logs to be attached to the structural calculations packet for submission to
the City of El Segundo.
Str-aactural Plans and Structural Calculations
• Complete structural analysis to determine if the existing foundation meets minimum
requirements per the referenced geotechnical design letter and code requirements for
overturning, embedment, and bearing capacity. The structural packet will be
supported by the geotechnical design parameters letter from Task 1.
• Complete structural analysis for the connection of the new scoreboard steel columns /
posts to the existing foundation provided they meet the minimum requirements
explained above.
• Provide structural details for the scoreboard column connection to the existing
foundation for submission to the City of El Segundo, and the contractor for use
during construction/installation.
City Plan Check
• GMU understands that City plan check comments will be limited. Response to a
single round of plan check comments will be provided under our scope if required.
Note:
Task 2 will be performed for the type of scoreboard which the city desires to have installed.
The construction plans will also include detailed assembly based on the manufacturer's
recommendations. Further, construction plans must include a note that the contractor must
obtain an electrical permit and a building permit. It must also have a note that the contractor
must provide the electrical connection to the scoreboard and must make sure that the
amperage/voltage is compatible with the manufacturer's requirements.

Agreement No. 6209A
Mr. Elias Sassoon, CITY OF EL SEGUNDO
PROPOSAL: Geotechnical and Structural Design Services, George Brett Field Scoreboard Foundation, City of El
Segundo, CA
Schedule — We anticipate that we can mark the site for dig -alert within 1-week from notice to
proceed. Investigation can be completed within 2-weeks from notice to proceed. Upon
completion of investigation, we anticipate an additional week for lab testing followed by an
additional 2-weeks for design parameters letter, structural design, and plans. Total of up to 5
weeks for completion of all deliverables.
ESTIMATED FEE
We will provide the above outline scope of work on a time -and -materials basis in accordance with
the attached 2021 Schedule of Charges. The estimated cost for each task is as follows:
Task 1 — Geotechnical Investigation... .............. ........ .................. . ..........$ 7,500
Task 2 — Geotechnical Laboratory Testing................................................................$ 2,750
Task 2 — Geotechnical Engineering Analysis and Structural Design Services,..........$ 5,500
➢ Total Estimated Cost (Tasks 1 through 3)......................................S 15,750
Please notify us immediately if the proposed scope of services does not meet your current needs, or
if any significant changes are made to the proposed development so that we can revise our scope of
services. Revision of the scope of services may affect the estimated fee.
LIMITATIONS
The proposed budget is dependent on the following items:
The above costs include a single round of response to plan check comments.
Analysis of existing scoreboard foundations are limited to external stability based on size
and embedment only. Concrete strength, amount and size of reinforcement, flexural and
shear strength of existing footings will not be analyzed or discussed in our final report.
If it is found that the existing foundation is insufficient based on external stability an
additional / modified proposal may be provided for a complete design of new scoreboard
foundations
