Description:
Change Order #2 is being issued to allocate contingency funds for new line items due to PCMs 9, 10, and 11.
PCM 9 was issued to allow for the installation of epoxy liner on one sanitary sewer manhole. The original
design anticipated the installation of cast-in-place manholes or pre-cast manholes. Epoxy lining is only
required for pre-cast manholes per City standard construction specifications. However, this requirement was
not clearly indicated in the Contract Documents. The Contractor is not able to install cast-in-place manholes
and has requested a contract modification to permit the installation of epoxy liner on the proposed pre-cast
sanitary sewer manhole.
PCM 10 was issued due to unreliable record information regarding the proposed connection location for the
30-inch pump station supply line, as well as several unidentified fiber conduits runs. To accommodate
unforeseen conditions, the proposed 30-inch supply line connection was revised to include tapping of an
existing 42-inch water line as well as an additional 30-inch gate valve and vault. Additionally, the proposed 36-
inch discharge line alignment was also revised to include additional footage of line to be installed by tunneling
to accommodate unknown fiber duct banks.
PCM 11 was issued to include revisions to fiber conduit requested by City IT department which were not
required during design review.

SCOPE OF SERVICES
Updated 5/18/2022
Description of prior Amendment(s)/Change Order(s):
PCM-01 Slab and Wall Control Joints In response to RFI No. 2 structural engineering team determined that it was
preferable to control cracking in basement mat slab and walls. Total Cost: $8,799.93
PCM-02 Electrical Room Conductor Revisions In response to RFIs No. 7, 9, and 12, several electrical room components
were rearranged to accommodate larger VFD cabinets. The only cost component was to provide conductor wiring from
the DME Transformer to the Utility Disconnect. DME reviewed and provided comments 5 times which had us moving the
meter to and from the transformer leading to confusion as to whether DME would be providing conductor cabling up to
their building mounted meter which they requested. Total Cost: $24,648.77
PCM-03 Roof Joist Design In response to RFI No. 6 truss designer requested more data regarding requirements for truss
design. Vendor has indicated that design changes resulted in approximately 1.5 tons of additional materials. Total Cost:
$11,055.07
PCM-04 Steel Pipe Outlets In response to RFI No. 13 Kimley-Horn requested Contractor to provide 4” flanged outlets
with blind flanges for all small connections. This was previously shown just for air release valves but will provide a
maintenance benefit if also provided for 2-water taps, and 6 – pressure switch/transducer taps in lieu of threaded
outlets. Total Cost: $6,549.14
PCM-06 Foundation Subgrade Revisions In response to RFI No. 21 Kimley-Horn revised mat foundation requirements as
limestone elevation on-site was found to vary by several feet across the basement. Initial design intended for mat
foundation to be cast against undisturbed limestone (unformed). However, due actual elevation and loose soil, design
was required to be modified to permit additional excavation and to form mat foundation. Total Cost: $112,165.34

ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, City of Denton (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 electronically through your DocuSign, Inc.
(DocuSign) Express user account. Please read the information below carefully and thoroughly,
and if you can access this information electronically to your satisfaction and agree to these terms
and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of
this document.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. For such copies, as long as you are an authorized user of the
DocuSign system you will have the ability to download and print any documents we send to you
through your DocuSign user account 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
If you decide to receive notices and disclosures from us electronically, you may at any time
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. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your
DocuSign account. This will indicate to us that you have withdrawn your consent to receive
required notices and disclosures electronically from us and you will no longer be able to use your
DocuSign Express user account to receive required notices and consents electronically from us
or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through your DocuSign user account all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or
made available to you during the course of our relationship with you. To reduce the chance of
you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
