INFORMATIONAL MEMORANDUM

FROM: Bob Giberson, Public Works Director

DATE: July 6, 2012
SUBJECT: Tukwila Communitv Center Sorav Park Sewer Connection
Project No. 91030101
Bid Award
ISSUE
Award bid to Goodfellow Bros., Inc., for the installation of an outside drop connection on the existing King
County sewer manhole that serves the Tukwila Community Center (TCC).
BACKGROUND
In 2008 the City installed a water spray park at the northwest corner of TCC. At that time it was decided to
install a temporary inside drop connection to the King County Metro sewer manhole and, at a later date,
install the outside drop connection required by King County. A sewer drop connection is required when
the elevation change from the building to the sewer main is too extreme to gradually connect to the sewer
main (which can be 14 feet deep). An outside drop for a sewer manhole connection is preferred as the
pipe is then not in the manhole structure and will not interfere with maintenance.
DISCUSSION
The City advertised the project on May 24 and 31, 2012. Four bids were received and opened on June
14, 2012. The bids were checked and tabulated and one minor math error was found in the bids.
The low bid was from Gary Harper Construction in the amount of $41,500.50 including sales tax. Mr.
Harper was contacted and asked if he thought his bid numbers were correct. He returned a letter to the
City stating that he had an error in Bid Item 10 and was requesting to withdrawal his bid (see attached
letter from Gary Harper Construction). The City has accepted Gary Harper's bid withdrawal based on
standard specifications.
The second lowest bidder, Goodfellow Bros., Inc., submitted their bid with one minor math error in their
grand total by $0.50. The bid tab reflects the corrected total. References were checked on similar projects
and it was reported that Goodfellow Bros., Inc. performed quality work.
FINANCIAL IMPACT
Funds for this project are in the 301 Parks Fund:

Re: Tukwila Community Center (TCC) spray park manhole connection
Dear Mike,
After reviewing my bid, I discovered a mathematical error in bid Item #10. When
I was adding it up I missed the 9 in the 9,500.00 figure. I have attached a copy
of my tabulation sheet as evidence. Therefore, I am requesting relief from the
responsibilities of Award.
Under penalty of perjury, 1 declare the above statement to be true and I certify
that the attached work sheets are the ones used to prepare the bid.
