FROM: J. MICHAEL WALFORD, PUBLIC WORKS DIRECTOR
DATE: April 20, 1993
SUBJECT: Approve Addendum No. 1 for the Assessment District 1992-1 Project.
Project No. 4500-6X5181-92
Specific Request(s) or Recommendations) & Background & Justification
I. RECOMMENDED ACTION:
APPROVE prior issuance of Addendum No. 1 for the project, advertised by the Board on
February 23, 1992.
II. FINANCIAL IMPACT:
Approval of this Addendum will result in no change to the original estimated contract cost,
$987,000, funded by Assessment District 1992-1 (100%).
III. REASONS FOR RECOMMENDATION/BACKGROUND:
The Addendum is needed to allow bidding contractors to substitute plastic pipe for reinforced
concrete pipe in some of the pay items for this contract, possibly resulting in lower bid prices.
Plastic pipe, as specified in the Addendum, is an acceptable alternative to reinforced concrete
pipe for use in State and County projects.
IV. CONSEQUENCES OF NEGATIVE ACTION:
Failure to allow bidding contractors the choice of an acceptable substitute in pipe selection
could result in higher bid prices for some of the pay items in this contract.
