CUDJOE KEY LANDFILL EXPANSION
CHANGE ORDER #2
ATTACHMENT B
The following provides a detail explanation for each item listed on Attachment A.
GENERAL (ITEMS 1 THRU 4)
Lined landfill cells are typically designed with two
(2) feet of porous sand covering
the plastic liner. This sand protects the
liner from damage during the
landfill operation and is designed to facilitate the drainage of leachate thru
the landfill to the collection system. The
design of the Cudjoe Expansion
utilizes screened incinerator ash in lieu of this sand. Initial tests of the raw
incinerator ash indicated that 50% to 60%
of the material volume would be
available after screening out all material greater
than 1/4". Utilization of this
screened ash in lieu of silica sand resulted
in an estimated $440,000 material
cost savings for the construction of the six (6) acre expansion area. (It
should be noted that due to the solubility
of the locally manufactured sand
in leachate it is not suitable for this
application). Consequently, the
construction contract was bid and issued on
the basis of the County supplying
the raw incinerator ash material which was
to be subsequently screened and
placed by the contractor.
The majority of the estimated required raw ash volume was stockpiled prior to
issuing the contractors notice to proceed. The balance of the amount
required would be supplied during construction.
As the contractor proceeded with the ash screening operation it became evident
that only 30% to 40% of the raw ash volume was suitable for use as liner
cover material. This reduced yield prohibited the County from providing the
total quantity required to complete the project as planned and resulted in the
following specific changes to the contract:
1. Additional Demobilization and Remobilization Costs of $7386.64
When the contractor depleted the ash supply (7/26/90), he was directed to
demobilize his ash screening and handling equipment while the County
continued to stockpile raw ash material. The contractor remained
demobilized until 10/17/90 during which time some 6250 cy. of raw ash were
stockpiled. This equated to approximately 2450 cy. of screened ash. This
amount of screened ash resulted in a savings of approximately $51,000 in
potential sand costs which more than off -set the additional demobilization/
remobilization cost of $7386.64.
2. Additional Geotextile Costs of $18,150
This material covers the plastic liner prior to the installation of the liner
cover sand. This fabric is subject to degradation when exposed to ultraviolet
rays for more than 30 days. Consequently the geotextile that was installed
prior to the contractor's demobilization and not covered by ash had to be
replaced. However, this cost was again off -set by the sand material cost
savings realized by utilizing the screened ash stockpiled during the
demobilization period rather than purchasing silica sand.
3. Silica Sand Liner Cover Material Additional Estimated Cost of $258,500
As previously stated with the reduced yield of screened ash material the
project would have to be completed utilizing silica sand as a liner cover
material. Quotations for supplying and delivery were solicited thru the
contractor with prices ranging from $17.66/T. to $26.75/T. as follows:
(including tax):
a. Conrad Yelvington $17.66/T.
b. Tarmac 23.00/T.
C. Florida Rock 26.75/T.
d. Davis Gravel & Sand 23.50/T.
A total installation price to include all labor, material, overhead and profit
of $23.50 per ton was subsequently negotiated with the contractor. Pay
quantities are to be determined by actual weight delivered to the site as
weighed at the landfill scales. It is estimated that approximately 11,000
tons will be required to complete the project.
Although this is an additional cost to it should be noted that utilizing the
screened ash to the extent that it was resulted in an approximate savings of
$208,300 in sand material costs.
4. Decrease Ash Quantity Contract Cost of $19,277
In that the total estimated contract amount of 16,190 cy. of ash was not
available the contract amount will be decreased to the actual amount
installed currently estimated at 10,980 cys.
The following items incurred during construction of the project and are not related
to the sand/ash issues discussed above.
5. Ball/Check Valve Material Change Credit of $3000
The engineer approved utilization of polypropolene material in lieu of the
polyvinylidene fluoride material originally specified resulting in a $3000
savings on these items.
6. Replace Ground Water Monitoring Well Credit of $1200
During construction the contractor damaged an existing monitoring well. The
$1200 cost to the County for replacing this well is deducted from the
contract amount.
