RE: Grapevine Creek Sewer Branch I & II
Dear Mr. Griffin:
Bids were received on September 29, 1992 for the above referenced project.
KENKO, Inc. was the apparent low bidder with a bid of $2,561,212.50 for both
Branches I & II. Attachment "A" lists the bidders and their bids. Attachment "B"
shows the complete bid tabulation with unit prices.
Alternative Consideration. We requested the low bidder, KENKO, Inc. to
re-evaluate their bid with consideration for Microtunneling East Bethel Road.
Attachment "C" provides their alternative costs. The bottom line is: KENKO, Inc. is
willing to give a lump sum deduction of $65,000.00 from the unit prices bid.
Therefore, the net additional cost to the City would be $210,366.00 for
Microtunnelling East Bethel Road.
Attachment "D" is information obtained from KENKO, Inc. regarding their
experience, financial statement, and bonding. Also included is information regarding
