CONTRACT 2009-9, LANDFILL SCALE REPLACEMENT
ADDENDUM NO. 1
The following changes, modifications and additions shall be made to the contract as follows:
1.) Section 11.2, Scale Abandonment
The last sentence of paragraph 3 shall be revised as follows:
Note the new approach on the entrance side is 10 feet wide x 14 feet long and the
approach on the exit side of new scale is 10 feet wide x 25 feet long. These dimensions
apply to the Base Bid. An Alternate Bid has been added for an 11-foot wide scale. The
length dimensions are the same as noted, but the width dimension is increased to 11 feet
for the Alternate Bid.
Plan Sheet 1 of 1 shows the depth of the existing scale pit as 4 feet. The actual depth is
6 feet. Please note this change and allow for an additional 2 feet of compacted backfill
material for the pit which will be compacted in 6-inch lifts to 95% Modified Proctor
Density.
2.) Section 11.4, New Scale Installation
Paragraph 5 of this section shall be changed with the following language:
The minimum dimensions of the scale shall be 70 feet in length x 10 feet in width for the
Base Bid and 70 feet in length and 11 feet in width for the Alternate Bid and include a
poured-in-place concrete deck of minimum 8-inch thickness.
Modify paragraph 3 on page 6 of 8 of the specifications which notes the entrance
approach length of 10 feet, which should be modified to 14 feet, and the length on the
exit approach of 20 feet should be modified to 25 feet. The 10-foot width of the entrance
and exit slabs is for the Base Bid. The Alternate Bid, which is added as part of this
Addendum, shall include the extra cost for an 11-foot wide entrance and exit slab.

ADDENDUM NO. 1
3.) Section 11.3, New Scale Installation
Paragraph 2 on page 7 of 8 shall be modified to read as follows:
The City is recommending side access for service and maintenance of the scale
equipment. Some scale manufacturers provide top access only. The City will allow top
access panels over load cells only on select equipment models. The top access panels
must be of stainless steel construction to be allowed.
Add the following paragraph:
The Contract did not specify any platform and/or railing over the side service area for the
pitless type scales with side access for maintenance. Any required platforms or railings
will be installed by others after completion of this Contract. This work is not part of either
the Base Bid or the Alternate Bid proposals.
4.) Revised Bid Proposal
The Contractor shall use the revised Bid Proposal attached to this Addendum.
The changes will include a Base Bid, which will be for a 10-foot wide new scale system.
Added to the Bid Proposal is an Alternate Bid item for the same scale description in Bid
Item No. 2 but for an 11-foot wide scale versus the 10-foot in the Base Bid.
The Alternate Bid for 11-foot width scale shall include the extra width for support slab,
extra base preparation, and extra width on approach of entrance and exit slabs to the
scale. The extra width scale will result in a minor modification of the cross-section on the
plan. The extra one-foot width will be added to the south side of the section, away from
the scale house.
