Cost & Time Change Summary
Pearlandtx.gov/projects
Description of Work
6/10/2026
In the early stages of the project, the design engineer introduced design alternatives for the project to assess possible
savings if the scope were to change. The alternatives were reviewed, discussed and approved by the City project
team and City Engineer in a meeting held 4/3/24 . Savings were established in a document titled "Veterans Drainage
Improvements Detention Pond Alternatives Analysis" dated 4/29/24. Overall cost savings were estimated to be
$2.1M if a new detention pond was installed along Veterans Drive as opposed to the original scope that involved
more piping. The initial contract scope did not include the newly proposed detention pond hence the cost proposal.

Re: Revised Supplemental Geotechnical Investigation Proposal
City of Pearland Veterans Drive Improvements
From W. Walnut Street to Mary’s Creek
Pearland, Texas
AEC Proposal No. G2023-05-06S1R1
Dear Mr. Qaddo,
Aviles Engineering Corporation (AEC) is pleased to present this revised supplemental geotechnical
investigation proposal for the City of Pearland’s proposed Veterans Drive Improvements project, from W.
Walnut Street to Mary’s Creek, in Pearland, Texas. Based on the schematic drawing provided, the
additional scope includes construction of a detention basin southeast of the intersection of Veterans Drive
and Summer Lane. According to the information provided by you, the proposed detention basin will have
a maximum depth of approximately 10 feet. Based on the schematic drawing provided, the proposed
detention basin area will be approximately 1.2 acres. AEC assumes that the services in this supplemental
proposal will be performed at the same time as AEC’s proposal for the roadway drainage improvements,
AEC Proposal G2023-05-06, dated May 11, 2023.
To cover the proposed detention basin, AEC proposes to drill a total of one soil boring (Boring B-6) to 20
feet deep. The total drilling footage is 20 feet. A Proposed Boring Location Plan (showing the
supplemental proposed boring location as well as the proposed roadway drainage boring locations) is
presented on Plate 1, in the Attachments. We will perform a site reconnaissance prior to drilling and
mark the boring location. We will also contact the Texas 811 System to confirm utility locations;
however, Texas 811 does not locate water, sanitary, or storm sewer lines. We request that any existing
underground utility drawings of the project alignment be provided to AEC prior to mobilization of the
drill rig.
Based on aerial photographs, AEC assumes that the access to the boring in the proposed basin area will
require a buggy-mounted drilling rig. AEC anticipates that tree clearing will be required to access the
boring location in the proposed basin area. For the boring, we will collect samples continuously at 2-foot
intervals from the ground surface to a depth of 20 feet. Undisturbed samples will be obtained of cohesive
soils by pushing a Shelby tube (ASTM D-1587). Standard Penetration Test samples will be obtained of
granular soils (ASTM D-1586). Representative portions of all soil samples will be sealed, packaged, and
transported to our laboratory. We will note any visual evidence or odor indicating hazardous materials if
encountered in the samples. Water level readings will be noted during drilling and obtained upon
completion of drilling. Upon completion of drilling, the borehole will be backfilled with bentonite chips.
AEC requests that Gauge Engineering arrange right of entry access to the detention pond property before
mobilization of the drill rig.
Laboratory testing may consist of moisture contents, Atterberg limits, percentage passing No. 200 sieve,
sieve analysis, unconfined compression (UC), and unconsolidated-undrained (UU) triaxial tests
depending on the soil types encountered. A consolidated-undrained (CU) triaxial test and crumb tests will
be performed for the detention basin boring depending on the soil types encountered.

Page 2 of 3
We will analyze the field and laboratory data to develop geotechnical engineering recommendations for:
(i) sieve analysis and double hydrometer test results for detention basin, evaluation if the soils at the site
are erodible or dispersive, and liner requirements if necessary; (ii) slope stability analyses on a selected
cross-section for the detention basin, and recommendations for the stable slope inclination; and (iii)
construction and groundwater control recommendations for the proposed improvements. We will present
our findings and recommendations as a supplement to the geotechnical engineering report for the roadway
drainage improvements.
The estimated lump sum fee for our services is $18,359.50 as presented on the Itemized Fee Estimate in
the Attachments. The fees are based on the following assumptions: (1) the field personnel will use Level
D protection during the field exploration; (2) no standby time (weather-related or incurred due to reasons
beyond our control) is included; and (3) surveying, environmental testing and evaluation, and
construction document review are not included.
AEC understands that the notice to proceed for the roadway alignment and the detention basin will be
provided at the same time, and all the field work for the roadway drainage and the detention pond will be
performed at the same time. After receiving notice to proceed and right of entry to private properties
along the alignment, AEC will perform a site reconnaissance within 3 days and contact Texas 811 to clear
utilities at the boring locations. Weather permitting, and assuming no field delays, we plan to start the
field exploration about 1 to 2 weeks after all utilities are cleared. The field exploration for the additional
detention pond scope will take approximately one day. Laboratory soil testing for the additional detention
pond scope will require three to four weeks (due to CU triaxial test) to complete after completion of the
drilling, and the draft geotechnical report (for the original roadway drainage scope as well as the
additional detention pond scope) will take 2 to 3 weeks after laboratory testing is completed. We will
submit the final geotechnical report two weeks after we receive review comments on the draft report. The
provided time frame is an estimate based on AEC’s current schedule at the time this proposal was written
and will remain valid for 60 days from the date of the proposal. If project authorization is received after
60 days, then the schedule estimated herein may be subject to change.
If any of the project details described in this proposal are incorrect or the scope described or the
assumptions listed need to be revised, please inform us immediately so we can revise the proposal as
necessary. Please sign and return this proposal (including terms and conditions) or issue AEC a
Professional Services Agreement (referencing this proposal) to authorize AEC to proceed with the
services. We appreciate the opportunity to present this proposal and look forward to working with you.

GEOTECHNICAL INVESTIGATION
TERMS AND CONDITIONS
STANDARD OF CARE
The CLIENT recognizes that actual subsurface conditions can vary from those observed and/or encountered at
locations where borings, surveys, or explorations are made, and that site conditions may change with time. Data
interpretations and recommendations by AVILES ENGINEERING will be based solely on information available to the
AVILES ENGINEERING during the investigation. AVILES ENGINEERING is responsible for those data,
interpretations, and recommendations, but will not be responsible for other parties’ interpretations or use of the
information developed.
The CLIENT should expect AVILES ENGINEERING to perform Services under this PROPOSAL/AGREEMENT in
a manner consistent with the level of care and skill ordinarily exercised by members of the engineering profession
practicing contemporaneously under similar conditions in the locality of the project. No other warranty, expressed or
implied, is made.
SCOPE OF SERVICES
AVILES ENGINEERING will develop a scope of services based on the project information provided by the CLIENT.
AVILES ENGINEERING shall not be responsible for problems arising due to inadequate number of borings and/or
depths dictated or required by others or inadequate engineering analyses, if the CLIENT reduces the scope of services
and/or provides insufficient or invalid project or other relevant information to AVILES ENGINEERING. In the event
the CLIENT or his representative orders work described in this PROPOSAL/AGREEMENT, that action shall
constitute the CLIENT’s acceptance of this PROPOSAL/AGREEMENT and its terms and conditions
SITE ACCESS AND SITE CONDITIONS
The CLIENT will grant or obtain free access to the site for all equipment and personnel necessary for AVILES
ENGINEERING to perform the services described in this PROPOSAL/AGREEMENT, as well as provide location
data for all below and above ground structures, pipelines, and utilities. For such items encountered, not called to the
attention of AVILES ENGINEERING, the CLIENT shall assume responsibility for any resultant damages. AVILES
ENGINEERING will take reasonable precautions to minimize damage to the site, but it is understood by the CLIENT
that, in the normal course of work, some damage may occur, and the correction of such damage is not part of this
AGREEMENT. The CLIENT will notify AVILES ENGINEERING of any known toxic and/or hazardous materials
on site and shall assume responsibility for the cost of occurrences due to unknown toxic and/or hazardous materials on
site.
BILLING AND PAYMENT
The CLIENT will pay AVILES ENGINEERING the lump sum amount(s) shown in the PROPOSAL/AGREEMENT.
Invoices will be submitted to the CLIENT by AVILES ENGINEERING and will be due and payable within thirty (30)
days of the invoice date. CLIENT will pay an additional charge of 1.5 percent per month on any delinquent amount
and agrees to pay attorney’s fees and/or other costs involved in any required collection activity.
LIMITATION OF LIABILITY / INDEMNIFICATION
If at any time, there shall be or arise any liability on the part of AVILES ENGINEERING by virtue of this Agreement
or because of the relation hereby established, whether due to the negligence of AVILES ENGINEERING (including
gross negligence) or otherwise, such liability is and shall be limited to a sum equal in amount to the fee charged by
AVILES ENGINEERING. AVILES ENGINEERING and CLIENT agree to indemnify each other from any claims,
etc., including attorney’s fees and litigation costs, to the proportionate extent caused by each party’s own negligence.
If AVILES ENGINEERING is found to be prevalent in any third party lawsuits relating to this AGREEMENT, the
CLIENT shall pay all AVILES ENGINEERING costs, including legal fees, that were incurred as a result thereof.
