Proposal for Additional Work Request
Dear Mr. Wimmer,
Bengal Engineering is submitting our request for additional services and fee associated with the above
referenced project.
As documented in the PDT Meeting Minutes #8 dated February 10, 2015, the CVWD 54" Mid -Valley
Pipeline was not able to be located during the original potholing investigation conducted in October
2014. This is due to insufficient location data provided by CVWD at that time. Subsequently, CVWD had
been unable to provide the location of the pipeline with certainty, therefore the location of this key
pipeline remains unknown.
In addition, as discussed at the last two PDT Meetings, this project is a Type I project due to the changes
in the roadway profile. If there are noise sensitive receivers within the project area, a Type I project
requires a Noise Technical Report that includes a model for existing, no build, and build conditions. The
mobile homes and residences adjacent to the project location are considered sensitive receivers.
According to the PES, the project proposes to relocate the mobile homes to an area within the same
location, and they will still have to be addressed in the Noise Study. In the event that the mobile homes
cannot be relocated in the same location, due to the lots being unusable for this purpose, the next line
of mobile homes will constitute the new sensitive receivers.
Attached are our Scope of Services and proposed fee.
The format for this additional work request is "Time and Materials" with a not to exceed price as shown.
Because of inability to predict the effort required at each individual requested location the cost estimate
shown herein are "budget figures, not to exceed".
Sincerely,

Proposal for Additional Services
Submitted to City of La Quinta

Scope of Services, "Exhibit A":
Task 1.0 Utility Potholing
Our subcontractor, "C Below", working under the direction of Bengal Engineering, shall perform the
potholing investigation detailed below.
r
Utility Potholing and Data Collection. Bengal plans to locate the 54" Mid -Valley Pipeline and the 33"
lateral connection. First, we will coordinate with CVWD locate the pipeline, along with having our
surveyor stake out the "Record Alignment" as provided to us by CVWD. Next, we will pothole the Mid -
Valley pipeline and the lateral, coordinating both with our subcontractor, and with CVWD to oversee our
operations. Our project survey team will also be on site to provide data collection of the pipe locations.
Finally, we will compile the completed utility base map which will be used throughout the project.
At this time Bengal anticipates up to five new potholes to locate these features for the project.
However, this potholing is an uncertain undertaking because CVWD has not be able to find surveying
records for the construction, and the locations CVWD provided for previous potholing proved to be
offset from the location where they now believe the pipeline to be located. In addition, the pipeline is
deeply -buried.
Therefore we have requested a fee for additional potholes, should we need to continue potholing to
find the line. Each pothole in addition to the five included in the base budget, would be undertaken at a
unit cost per pothole with no additional mobilization. Subconsultant ("C Below") estimate is provided as
part of this request.
Task 2.0 Utility Survey
Section 37 under the direction of Bengal Engineering shall locate horizontally and vertically the exposed
utilities as indicated in Task 1 for use throughout the project. The survey data will be plotted within the
utility plan and field notes and digital data will be made available for the City's and CVWD use.
Task 3.0 Project Management
Bengal Engineering will manage the additional work by tracking the schedule, budget, QA/QC and
coordination with CVWD to be sure the timing of the utility location services coincides with the
potholing and survey services.
Task 4.0 Noise Modeling
Parsons Brinckerhoff under the direction of Bengal Engineering will perform noise modeling for the
existing, no build and build conditions for the project on the mobile home park site. The results of the

modeling will be summarized in the final Noise Report and any noise attenuation measures will be noted
and identified.
For the below noted fee, we propose to shift fee amounts set aside for an originally scoped Biological
Assessment and Section 7 Consultation/Coordination, which at this time we do not believe we will need
on this project. The proposed request will not increase the overall project fee, rather it will shift monies
around to accommodate the required services and activities.
Task 1.0 Utility Potholing (5 potholes) $6,900 (1)
Task 2.0 Utility Survey $2,000
Task 3.0 Project Management (Anticipated 8 hours) $1,200
Task 4.0 Noise Modeling $6,800 (2)
ContinLrency for 3 Additional Potholes 1000 1 location up to depth of 25' 3 000 1
Total Not to Exceed Fee: $19,900
We propose
Bengal Engineering Hourly Rate $150/hr
Reimbursable Expenses will be billed at cost +15%.
(1) Potholes will be invoiced on a per each basis, based on the number and depth range
required to locate the facility.
(2) Fee breaks down into the following hours per classification:
Project Manager — 6 hours @ $205
Sr. Engineer/Planner — 20 hours @ $188
Technical Specialist — 6 hours @ $204
