CHANGE ORDER MEMORANDUM
TO: RAMZI AWWAD, DIRECTOR OF PUBLIC WORKS
FROM: ALAN BRAATVEDT, SUNBEAM CONSULTING
DATE: MARCH 12, 2024
SUBJECT: RESTROOM IMPROVEMENTS AT THE POINT VICENTE
INTERPRETIVE CENTER
CONSTRUCTION CHANGE ORDER NUMBER: 3
Description of Construction Change Order
Demolish the interfering unforeseen concrete masonry unit (CMU) wall located between
the existing IT Room and Men’s Restroom and patch associated floor base to allow for
buildout of improvements per the contract plans.
Justification
During demolition and site prep for the interior restrooms, an unforeseen CMU wall was
discovered when demolishing what was expected (per original contract) to be drywall
between the IT room and men’s restroom.
The change resulted in an additional work (labor, materials) not accounted for in the
original contract documents and associated contractor’s bid due to the additional level
of effort, compared with drywall, required to demolish & haul away the CMU wall and
repair the connected floor base. Therefore a change order needs to be issued to
account for the changes to the contract documents and the associated additional costs.
As compared with drywall:
-CMU is significantly heavier, wider, and stronger, requiring significantly more time/labor
to demolish and costs more to haul off-site for disposal.
-Since the CMU wall is installed directly to the floor base, it’s not possible to demo the
CMU wall without requiring minor restoration to the floor base to make sure the surface
is even & level before the contract-specified tile floor is installed.
Cost Analysis
An independent estimation of the effort required to demolish and dispose of the CMU wall
and repair the floor base was made. The estimate was based on the actual time taken for
the work performed and applied to the going labor rates for the respective craft. Labor
hours were reduced to reflect the labor that would have been otherwise needed to
demolition a drywall as originally anticipated per the contract plans. The proposal received

ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, City of Rancho Palos Verdes (we, us or Company) may be required by law to
provide to you certain written notices or disclosures. Described below are the terms and
conditions for providing to you such notices and disclosures electronicall y through the DocuSign
system. Please read the information below carefully and thoroughly, and if you can access this
information electronically to your satisfaction and agree to this Electronic Record and Signature
Disclosure (ERSD), please confirm your agreement by selecting the check-box next to ‘I agree to
use electronic records and signatures’ before clicking ‘CONTINUE’ within the DocuSign

Getting paper copies
At any time, you may request from us a paper copy of any record provided or made av ailable
electronically to you by us. You will have the ability to download and print documents we send
to you through the DocuSign system during and immediately after the signing session and, if you
elect to create a DocuSign account, you may access the documents for a limited period of time
(usually 30 days) after such documents are first sent to you. After such time, if you wish for us to
send you paper copies of any such documents from our office to you, you will be charged a
$0.00 per-page fee. You may request delivery of such paper copies from us by following the
procedure described below.
Withdrawing your consent

change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. Further, you will no longer be able to use the DocuSign system to
receive required notices and consents electronically from us or to sign electronically documents
from us.
