Design Fee Amendment No. 3
Dear Ms. Johnson,
This letter is to provide information regarding the change in scope on the Water Department work
on the above referenced project.
The water department has requested that Dannenbaum Engineering add the design and
construction of sanitary sewer lateral L-1661 from existing Station 2+37 to Station 4+80 to our
contract. For your use, the Supplemental Fee Summary and the Engineer's Opinion of
Construction Cost are attached. Our opinion of construction cost is $18,507.00 with additional
surveying and engineering costs of$1,718.17. Since the design is the replacement of an existing
lateral in place, the necessity of utility easements are not anticipated and such costs are not
included.
Please inform us of the City's approval of the contract changes. If you have any questions in the
meantime, please do not hesitate to call.
Sincerely,
i�

MEMORANDUM
TO: A. Douglas Rademaker, Director, DOE and
Mike Groomer, Assistant City Manager
FROM: Dena Johnson, DOE
DATE: June 6, 2000
RE: AMENDMENT NO. 3 TO PAVEMENT RECONSTRUCTION AND WATER AND
SANITARY SEWER REPLACEMENTS ON SANBORN AVENUE (SCOTT TO
EAST LANCASTER); CAMILLA STREET (CONNER TO SOUTH BEACH);
KOCH STREET (CONNER TO SOUTH BEACH); PARKDALE STREET (KOCH
TO NORTH DEAD END) AND SARGENT AVENUE (EAST LANCASTER TO
MEADOWBROOK). SEWER PROJECT NO. PS46-070460134010
This amendment will reimburse Dannenbaum Engineering Corporation for the additional engi-
neering services they provided on the Water Department portion of the design contract.
It has been determined that it is necessary to replace a severely deteriorated 250 feet section of
sewer lateral L-1661 which is located within close proximity to this project. The poor condition of
the identified lateral was unknown prior to award of contract.
Dannenbaum Engineering Corporation, has requested reimbursement in the amount of$1,718.17
(Water Department cost) for the additional services that were provided thereby increasing the con-
tract fee from $140,544.78 (TPW; $77,970.44, Water; $31,297.88, Sewer; $31,276.46) to
$142,262.95 (TPW; $77,970.44, Water; $31,297.88, Sewer; $32,994.63). I believe this fee is fair
and reasonable for the additional services that were provided.
