TITLE: Amendment No. 1 to Professional Services Agreement with GMU Geotechnical,
Inc. for Marina Park Specialty Inspection and Material Testing Services (CAP09-
0070)
ABSTRACT:
GMU Geotechnical, Inc. (GMU) has been retained to provide specialty inspection and material testing
services for the Marina Park Project. Staff recommends approval of Professional Services Agreement No.
1 with GMU to allow for such services for the balance of the project construction duration.
RECOMMENDATION:
Approve Amendment No. 1 with GMU Geotechnical, Inc. of Rancho Santa Margarita, California, for
additional specialty inspection and material testing services for the Marina Park Project at a not -to- exceed
price of $158,758.00, and authorize the Mayor and City Clerk to execute Amendment No. 1.
FUNDING REQUIREMENTS:
Contract costs will be expensed to the Marina Park Project Account No. 7411- C4002002 as follows:
Vendor Purpose Amount
GMU Geotechnical, Inc. PSA Amendment No. 1 $ 158,758.00
Total: $ 158,758.00
DISCUSSION:
On November 13, 2013, the City entered into a professional services agreement (PSA) with GMU for a
contract amount of $206,487.00 to provide geotechnical, specialty and registered special inspection
services for the Marina Park Project.
During the course of the Package 2 (Marina Basin) construction, installation difficulties and unknown sub-
surface challenges with the stone column, concrete sheet pile and tieback installations were encountered,
which resulted in added and unanticipated oversight and testing efforts by GMU in orderto provide
6 -1
necessary quality control and oversight to overcome the issues.
It is expected that nearly all the allocated GMU inspection funds will be exhausted by the end of Package
2 (Marina Basin) construction. As a result, the scope of work and cost detailed in GMU's PSA needs to be
amended to cover the necessary oversight, inspection and testing work required to complete the Package
3 (Buildings and Site Work) and 4 (Docks) construction effort.
Staff has been pleased with GMU's work to date, and is comfortable making this recommendation.
Overall, the Marina Park project remains on budget and on schedule.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this action is not subject to the California Environmental Quality
Act ( "CEQA ") pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably
foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as
defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3.
The Final Environmental Impact Report for the Marina Park Project was adopted by City Council on May
11, 2010.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at
which the City Council considers the item).

In addition to the above described "revised cost estimate ", two new additional tasks need to be

1. RFI Consultants
At the request of the City, coating inspection tasks to be performed by RFI Consultants, Inc. were
added to our scope. The costs for these tasks will be incurred by RFI only and will be billed to the
City on a pass through basis with no market.
Fee Estimate: $11,620
2. Void Detection and Evaluation
At the conclusion of tie -back drilling two soil settlement areas (aka collapsed voids) were observed
in the field. To evaluate this occurrence as well as develop a procedure to verify within a reasonable
certainty that no additional voids exist, the following scope of work was performed over a 3 -4 week
period.
• Scope
o Equipment
GPR
Direct Push Rig
• Field Observations and oversight
o Footing probing
o GPR operations
• Footing bottom compaction operation
• Direct Push observations
• Field Meetings
• Professional
o Numerous meetings and teleconferences
o Data evaluation and analyses
o Interaction with GE of record
The costs for this scope as well as the cost for outside contractors (i.e. GPR testing and a Direct Push drill
rig and crew) are summarized below.
Equipment Costs: $20,125
Professional and Field Observation Costs: $13,500
Total Costs: $33,125
RED]
SUMMARY
Consequently, we respectfully request an increase in budget in the amount of $114,013 +$11,620
+ $33,125 = $158,758
All work is proposed to be billed on a time - and - material basis in accordance with the Marina Park fee
schedule contained in Appendix A. As always costs may vary depending on construction schedule,
quality of the work performed by the contractor, etc. (i.e., costs may be below or above the total cost).
However, we have done everything possible to estimate the remaining budget required to complete the
tasks (i.e. re- evaluated inspection man hours based on current schedules, met with overall project
manager and construction superintendent for phase 3 construction, etc.). Please do not hesitate to call
if you have any questions regarding this information or if you would like to discuss our qualifications in
further detail.
