Subject: Proposal — Additional Investigation and Structural Analysis Services —
George Brett Field Scoreboard Foundation, City of El Segundo,
California
Dear Mr. Sassoon:
GMU Structural Engineering is pleased to submit this proposal to provide additional investigation
and structural design services with the hope of confirming existing scoreboard foundation structural
properties, specifically amount and size of reinforcement and compression strength of concrete.
We propose to perform the following scope of work:
Existing Pier Footings - Additional Investigation Scope
Explore the site by performing one additional hand -excavated test -pit to a maximum
depth of 7-feet below existing grade, (pier that was not investigated to full depth
previously).
Determine the amount and size of existing pier foundation reinforcement. We will
work with a subcontractor on site the day of our investigation to scan and map
existing pier footings from the near surface to determine rebar size and spacing.
Although not guaranteed, GPR methods have been proven to be reliable in locating
steel reinforcement in concrete masses.
Determine concrete compressive strength of existing pier footings. We will work
with a subcontractor on site the day of our investigation to core and remove a
representative section of the existing pier footing for testing. A core approximately
2.5-inch-diameter by 6-inch-tall will be removed from each footing. Compression
testing will be completed by an accredited materials lab. We will core an area that
will have a negligible effect on the footing's overall strength, and we will patch back
the void with high strength concrete.
Take numerous Schmidt Hammer readings on both scoreboard pier footings and
correlate with compression test results.

Mr. Elias Sassoon, CITY OF EL SEGUNDO
PROPOSAL: Additional Investigation and Structural Analysis Services —George Brett Field Scoreboard Foundation,
City of El Segundo, CA
Existing Pier Footings - Additional Structural Analysis Scope
Determine minimum amount of steel reinforcement required for the pier footings
based on the determined concrete compression strength and design loadings.
Determine if existing pier footings are structurally sound with respect to material
strengths, and material volumes based on the design loadings from the proposed new
scoreboard sign.
Revise soils report based on new findings.
Schedule — We anticipate that we can complete the investigation specified above by mid to end
of next week. Obtaining reports from our subcontractors and completing our analysis should be
available within a week after completion of our field investigation.
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:
Additional Investigation... ....... ............... .,,,.,,,............ ... .., —$ 3,565
