Subject: Project Scope Changes No. 3
Landfill Regrading and Landfill Gas System Installation Project
Phase III - Lowerdeck Closure Design and Development Consulting
City of Burlingame Landfill, Burlingame, California
City Project No. 9117
WCC Project No. 941074NA
Dear Mr. Erbacher:
As we have discussed, the scope of work agreed upon with my April 7, 1998 memo is not the
scope of work currently needed for closure of the lowerdeck area of the landfill. At the time of
the April memo, it was assumed that we would utilize the foundation layer and final ballfield
surface drawings generated during the landfill regrading project.
Since then there have been a number of changes to the design to meet the City's Bayside Park
Master Plan. It was decided in August in a meeting with the City Public Works and Parks
Departments that these changes would be incorporated into the closure work as well as the
development work. In addition, it was requested that closure and geotechnical work in support
of the Park development be added as a task on this project.
This letter is to document these scope changes and to provide support for an increase in the
overall project budget.
SCOPE CHANGES
In general, the scope changes fall into the following categories:
Task 2100 (Grading and Cover Design)
• change in ballfield surface required several redesigns of clay surface
• increased complexity and area of the cap design
• three additional progress drawings required

Task 3100 (Meetings and Consultation)
• more meetings and conference calls to coordinate design
Task 3200 (Engineering Control Reports)
• additional progress reports due to additional project length
Task Group 5 (Development Assistance) - NEW TASKS
Task 5100 (Consulting)
• input to and review of development design plans and specifications relative to closure
Task 520E (Geotechnical Services)
• geotechnical investigation for development structures
• geotechnical review of development drawings
Task 5300 (Regulatory Interface)
• documentation required to change land use
• updating the Post -Closure Care Plan to incorporate all development changes
Task 2100
Change in Ballfield Surface In our April scoping memo (Attachment 1), it was agreed that our
design work would be to: re-establish the design grades, add clay, add Callander's drainage pipes
in the ballfietd and place two different cover soils (one for the ballfield, one for the west road).
When we began to re-establish the design grades, it was apparent that a large volume of soil
would have to be added and that the final ballfield would be both too high and slope the wrong
direction. It was decided for Callander to redesign the ballfield surface and Woodward -Clyde to
redesign the underlying clay surface.
These redesigns were made more difficult by the fact that there was not one topographic map
that showed the existing conditions at the landfill lowerdeck, the Wastewater Treatment Plant
and Bayside Park (all needed to tie final to existing surfaces). The necessary information was on
three separate topographies which posed a complex overlaying problem to obtain the information
in a usable 3-13 computer format. The 3-13 information was then used in generating the seven
different clay surface configurations necessary to optimize the ballfield surface. Quite a bit of
additional communication with Callander Associates staff was necessary to make these changes
and various cost estimates were developed to aid in analyzing the various clay surface to
minimize the costs. None of this redesign was in our original scope.
Increased Complexity and Area of Design. The original work was only for the landfill (ballfield
and west road). The area covered by the project new includes the ballfield area, the dog nm
(west road) area up to Airport Blvd and the new parking/tot lot area. Work along Airport Blvd. is
not in this new work area

Six sheets were assumed for the original drawing set. The sheets currently envisioned are:
• 1 cover sheet
• 1 notes and legend sheet
• 1 plan sheet existing topo with all existing pipes (using combined topo generated earlier)
• 1 plan sheet showing top of clay surface with existing topo as background
• 1 plan sheet shaving new sub -drainage piping (draining clay surface) and existing piping
with top of clay as background - new sheet
• 1 plan sheet showing surface extent of various cap types with coordinates (including
specialty capping for the wall)- new sheet
• i pian sheet showing nnai surface coniours with top of clay as backgrouna
3 detail sheets for cap type details, for transitions between cap types, for drainage piping and
"tie to existing structures" details (one sheet originally assumed)
10 sheets total
Assumptions in these plans are:
• no profile sheets will be needed for the subdrains;
• surface water drainage will be added during development;
• material types will be similar to those used in Phase R;
• foundation details for the wall, light poles, etc. will be in the development drawings.
Additional Progress Drawings. In our April work scope, the work was fairly straightforward,
therefore only a 30%, 901/o and 100% (for bid) drawing set was assumed. However, after the
need for a new design was noted in reviewing the 30% submittal, a 60% submittal was made to
show the new site topography, the new surface design and the new top of clay contours. Because
of the increased complexity of the cap and piping coordination, it is assumed that 75% and 95%
submittals will also be necessary in addition to the original 90% and 100% (for bid) sets.
Technical specifications will come with the 90% submittal and Project specifications (including
City special provisions) will come with the 95% and 100% submittals. The 90% submittal will
also be sent to the BCDC, in accordance with the City's permit.
Task 2100 Totals - Performing two rounds of submittals plus the out -of -scope work described
above utilized $42,500 of our $28,500 budget for this portion of the design task. Performing the
additional design work, developing the additional design drawing sheets, preparing the additional
submittals and responding to City and Callander comments is anticipated to cost $65,000. This
results in a requested increase of $79,000.

Task 3100
Additional Coordination Meetings/Calls. To accomplish the work for the tasks noted above,
quite a bit of communication will be necessary between Woodward -Clyde, Callander Associates
and the various City departments. An additional 40 project manager hours and 40 staff
engineer/designer hours are anticipated to finish the project. $9,200.
Task 3200
Additional Progress Reports. With the project lasting longer than anticipated, there will be
additional progress reports needed. While this budget has not yet been fully expended, it is
anticipated that an additional 20 project management hours will be needed for these reports,
$2,800.
TASK GROUP 5 - DEVELOPMENT ASSISTANCE
The City has requested that work in support of the development work being performed by
Callander be performed under this contract. The work is similar to that currently being done
under City contract 9117(3) and Woodward -Clyde contract 941074ND. The three subtasks
assumed for this work are: Consulting, Geotechnical Services and Regulatory Interface.
Additional subtasks can be added at the City's request. Specific work in those subtasks are
described below.
Task 5100
This is an on-call task. As the development design progresses, we will provide to the design
team information on design details, materials, procedures, etc. which meet the requirements of
the regulatory agencies. We will review plans and specifications prepared by the development
team.
For budgeting purposes, we have assumed 30 hours/month of the project manager's time and 10
hours/month engineering staff time for the 5 months of the development project for $25,500.
Task 5200
The work currently known for this task includes performing a geotechnical investigation for the
wall, the lighting foundations, the parking lot and the maintenance building. It is assumed that
the investigation will be with a cone penetrometer rig to minimize disturbance to the landfill. A
permit application/workplan will also be prepared for approval by the San Mateo County Health
Department prior to the investigation. The results of the investigation will be written up in a
technical memorandum with foundation recommendations.
Woodward -Clyde
Mr. Frank Erbacher, P.E.
October 13, 1998
Page 5
We will also review the development drawings for incorporation of the geotechnical
recommendations.
It is assumed that the geotechnical investigation work will be about $8000 for the field work and
$3000 for the preparation, results interpretation and recommendations. Assuming 4
development submittals, 24 senior geotechnical engineer hours are assumed ($3400). Total for
Task 5200 - $14,400.
Task 5300
For the topdeck, the regulatory agencies have accepted development plans and specifications
with a cover letter showing how it meets the regulatory requirements. It is anticipated that this
will be the case for the lowerdeck work. If that is the case, it is assumed that coordinating with
the regulators, preparing the submittal for City and Callander review, and finalizing and
submitting the plans to the regulators will cost $10,000. Assuming 10% to respond to agency
comments, the total cost should be $11,000.
The LEA has noted that postclosure development will require an update of the Postclosure
Maintenance Plan portion of the Landfill Closure Plan. It is assumed that this can be done as a
revision to the existing Closure Plan document (sending a revised Chapter 4). If that is the case, it
is assumed that coordinating with the regulators, preparing the submittal for City review, and
finalizing and submitting the document to the regulators will cost $5,000. Assuming 10% to
respond to agency comments, the total cost should be $5,500.
Total Task 5300 budget - $16,500
REQUESTED ADDMONAL BUDGET
As you can see from the many changes original scope noted above, the anticipated hours to
perform this work were not adequate for the scope of work currently anticipated. While this
involves many changes to the closure design, we feel that the decision to better coordinate the
closure and the development will minimize the long-term costs to the City.
Attached is a spreadsheet with the requested additional funding. This spreadsheet is an extension
of the spreadsheet attached to our second request for additional budget on this project and
includes all prior authorizations.

IN CLOSING
This letter documents the additional costs estimated to complete this project. The additional
costs are based on the additional work performed to date and the design work currently
anticipated and described above. As always, we will only have personnel working on the project
as needed to provide the level of design necessary to minimize construction costs and meet the
City and park development needs. All work will be on a time and materials basis, therefore we
will only charge for actual time spent on these tasks, to a maximum amount approved by the
City. In addition, we continue to perform this work under our rate schedule from 1994, when
this project began. This represents a 15% decrease from our 1998 rates.
We thank you for the opportunity ity to work with the City on this project and for your
understanding of the changes in project scope and budget. If there is further documentation we
can provide, please don't hesitate to ask.
Sincerely,
Linda J. Locke, P.E.
