Re: D.O.E.#2217 Wimberly Street—Merrimac to Wingate
City Secretary Contract#24711
Engineering Change Order No.2
Mr.Ehia:
Based on our meeting last week with the Water Department and the consultant performing the White
Settlement Road sewer replacement,it appears we have finally reached a viable solution for the siphon
problem at the intersection of Wimberly Street and Wingate Drive. Over the past two years,Graham
Associates has spent a considerable amount of time evaluating sewer options and I was glad to see the
solution being implemented,as part of the White Settlement Road project, was our preferred alternative
proposed in 2002. I believe we are now in a position to revise the Wimberly Street paving and utility plans
one last time and proceed with construction.
In accordance with your previous direction,I have tracked time devoted to evaluating sewer options and
revising previously approved plans related to the siphon issue. These charges fall into five categories,
itemized below.
1) Field survey of existing offsite sewer system downstream of the existing siphon: i)Currie
Street from Wingate to White Settlement Road and ii)Wimberly Street from St. Juliet to
White Settlement Road. Meet on-site with operations crews for vacuuming of manholes and
field survey of siphon inverts.
Senior Engineer 6 @ 110 660.00
Tech III 12 @ 65 780.00
Survey Crew 30 @ 100 3,000.00
Subtotal 4,440.00
2) Analysis of options for off-site sewer routes and siphon modifications. Present results in
letter report format and meet with Water Department on three occasions to discuss options.

3) Revise approved Wimberly Street paving, drainage and utility plans for shorter paving length.
This was to allow bidding and construction of the street without including the area where the
existing siphon is located. Revise contract documents and bid quantities accordingly.

Tech Ill 28 @ 65 1,820.00

Subtotal 6,535.00
4) Revise contract documents and bid quantities for new Special Conditions and MWBE
requirements implemented during the time period the project was waiting to bid.
Design Engineer 8 @ 75 600.00
Clerical 6 @ 35 210.00
Subtotal 810.00
5) Based on our meeting of last week,revise Wimberly plans once again to reflect installation of
21 inch dry line, leave existing 15 inch sewer line in place until White Settlement Road
project is constructed, and extend pavement limits to include the siphon area. Revise contract
documents and bid quantities accordingly.
Estimate Cost:
Senior Engineer 6 @ 110 660.00
Design Engineer 25 @ 75 1,875.00
Tech III 18 @ 65 1,170.00
Clerical 8@ 35 280.00
Subtotal 3,985.00
Since neither the work associated with sewer line replacement alternatives downstream of Wimberly Street,
the revisions necessary to coordinate with the White Settlement Road project,nor the pavement revisions to
approved plans were anticipated in the original design contract, I believe these services constitute
legitimate "additional services". We respectfully request our contract be amended in the amount of
$24,815.00 to reflect this additional work.
Sincerely,
GRAHAM ASSOI TES,INC.
