Globaltech, Inc.
Task Order No. U04-08-10 - Amendment 1
Preliminary Design Report
To Increase the Capacity ofthe East Water Treatment Plant
Design Build Services
to Evaluate Filter and Replace Filter Media in Filter#l
A. Background
The City of Boynton Beach (CITY) will be making improvements to the East Water Treatment
Plant (WTP) to increase its capacity. Currently, a Preliminary Design Report (PDR) is being
prepared by Globaltech, Inc. to identify improvements to be made to increase the plant capacity.
Filter tests conducted under the PDR project has identified that the west filter bank (Filters #1
through #4) are not currently able to perform to their original design capacity of 3 gpm per foot.
The reason for the reduction in filter capacity is unknown at this point and will require additional
investigation which is beyond the scope of the PDR. The reason for the reduced capacity could
range from clogged underdrain or gravel, undersized underdrain, debris in filter, faulty
hydraulics, or calcification of media which will require the media in the filter to be removed.
In order to determine the reason for the lower capacity in Filters # I through #4, the filter media
will need to be removed to check the condition of the gravel and underdrains. The CITY desires
to inspect and rehabilitate Filter #1 to assess the general condition of Filters # I through #4. The
filter media for Filter # I shall be removed and replaced and the filter shall be inspected. The
media will be replaced as it is estimated to be 20 years old. Plant staff cannot recall the filter
media ever being replaced or the underdrain inspected since the filters were modified in 1989.
After Filter # I has been inspected and rehabilitated, it can then be tested to determine if it can
operate at a higher capacity. This would indicate if the remaining filters could be operated at
higher capacity if they were also rehabilitated.
The CITY has requested that Globaltech, Inc (DESIGN-BUILDER) provide engineering and
construction services to remove and replace the media (gravel, sand, and anthracite) in Filter # 1.
In addition, the DESIGN-BUILDER will also inspect the condition of the existing gravel and
underdrain in Filter #1. It is currently assumed that the underdrain orifices will be slightly
plugged with calcium carbonate and are to be drilled out during the media replacement.
However, if the underdrains are determined to be in worse condition, the existing underdrains
could be replaced by the DESIGN-BUILDER with a similar style underdrain constructed of
plastic if replacement is approved by the CITY as accessed through an allowance. The
replacement underdrains shall be manufactured by Leopold, Roberts, or Tetra.
This Amendment I to Task Order No. U04-08-1O provides authorization for Globaltech, Inc., to
perform the requested evaluation and replacement services. The original Task Order was
approved by the City Commission on December 10,2008.
TASK ORDER No U04-0S-10 - Amendment I
B. Scope of Services
Task 1 - Filter Evaluation
The filter inspection and evaluation shall consist of the following:
. During filter media removal, the DESIGN-BUILDER shall visually inspect the condition
of the media for calcification and debris that may reduce the capacity of the media.
. After the filter media is removed, the DESIGN-BUILDER shall evaluate the condition of
the underdrains to determine if the orifice hole size has been reduced. A series of short
filter backwashes will be required to evaluate the underdrain without media.
. The DESIGN-BUILDER shall probe the orifice holes for signs of debris. If the
extremely small size of the orifice hole will allow a camera inserted, the DESIGN-
BUILDER shall also televise the underdrain if possible.
. With the assistance of the CITY and their pipeline camera, DESIGN-BUILDER shall
remove the 16" x 10" tee connecting the backwash supply line to the underdrain channel
of one filter section to inspect for accumulation of calcium or debris inside the channel.
The second section will be assumed to be in a similar condition and its piping shall not be
disassembled for televising.
. After the media has been replaced, the CITY shall operate the rehabilitated filter at the
original loading rate and at higher loading rates to be determined by the DESIGN-
BUILDER. Data from the filter loading tests provided from the CITY shall be evaluated
by the DESIGN-BUILDER.
Observations collected from the evaluation of the underdrains will be presented to the CITY in a
conditional assessment. The summary will make recommendations regarding repair or
replacement of the filter underdrains and the cost associated with the proposed alternatives.
CITY staff will then provide direction and authorization for DESIGN-BUILDER to move
forward with the repair or replacement of the underdrains and provide a separate authorization to
access all or a portion of the funding associated with the allowances included in the Section C -
Assumptions.
Task 2 - Media Replacement
The DESIGN BUILDER shall provide the following services to remove and replace the filter
media in the two sections of Filter #1.
. Prepare specification for new filter media for CITY's review
. Remove the existing gravel, sand, and anthracite by vacuuming the media out with a Vac
Truck. Removed media will be transferred on site to the existing sludge storage area for
ultimate disposal by the CITY.
. Pressure wash the two filter sections.
. Drill out the filter underdrain holes as required.
20f6
TASK ORDER No. U04.OS-10 -Amendment 1
. Furnish and install new replacement media in layers consistent with proper media
installation techniques.
. Disinfect filter media as required to place back in service.
C. Assumptions
In addition to the work items discussed above, the following assumptions were made in
establishing the scope of work and associated fee. Changes and/or modifications in the above
work items, or these assumptions, are considered an Additional Service Item under the terms of
the contract.
. Should the underdrain be damaged and need repair a $10,000 allowance has been set
aside to be used as approved by the CITY. The existing clay underdrain is no longer
manufactured; therefore, a repair may involve fabrication of new material to be used.
. Should the underdrain be determined to be in need of replacement, an $88,200 allowance
has been set aside to be used if needed as approved by the CITY. This allowance
assumes $50,000 for underdrains, $10,000 for underdrain hardware and accessories, and
a 2 week installation period from receiving the underdrains.
. The DESIGN-BUILDER will provide an on-site sanitary facility for the duration of the
project.
. The DESIGN-BUILDER will coordinate deliveries and unload media with their
equipment.
. The CITY will televise the underdrain with the DESIGN-BUILDER assistance and
provide video for the DESIGN-BUILDER to evaluate.
. The CITY will provide operation staff to assist the draining/filling and backwashing of
the filter with water as necessary for the removal and installation of media.
. The CITY will provide lay down area for storage of media and equipment on the East
WTP site as required for the work.
. The CITY will operate equipment as necessary for the operational testing and gather test
parameters as requested.
. The CITY will provide for the ultimate disposal of the removed filter media.
. The CITY will conduct bacteriological testing to determine when the filters are cleared
for service after media has been replaced.
. Project does not require bonding.
