Change Order
BACKGROUND: On October 26, 1999 the contractor on the 1999 Water Systems
Improvements Project, Mr. Gordon Gruhn, advised the City Inspector and Director of Public
Works, Messrs. Ernie Beadle and Robert Kosoy, that he encountered very unusual groundwater
conditions on East Coast Drive, from 12`h to 15`h Street. These conditions were very unusual to
Mr. Gruhn, who has been performing point repairs for the City since 1991 and has been the
City's annual point repair contractor since 1996, and is very familiar with most subsurface
conditions in the City. He was directed verbally to discontinue work in this area, proceed to
another area to avoid any delay in the total project time, and was advised to to submit a letter
outlining his request for additional payment.
On October 28, 1999 we received a letter from Gordon Gruhn outlining his request, discussed his
request with the design engineer, Smith and Gillespie, and on November 2, 1999 received a letter
from Gordon Gruhn further substantiating his request. On November 3, 1999 we received a
letter from Mr. Doug Layton, P.E. supporting Mr. Gruhn's request for additional payment.
BUDGET: Funds are available in the contingency for this project in the amount of $58,118
under Account No. 400-4001-533-6300.
RECOMMENDATION: Approve the proposed Change Order in the amount of $14,375.00.

RE: 1999 Water System Improvements, Cit<~ Bid No. 9899-26
Dear Mr. Kosov:
This letter is a follow up of our phone conversation on Oct. 26, 1999, regarding thc; need to install
wellpoints to allow fot th.e ins±alIation of the new h~elz~e inch water line on East Coast Dr. and Fourteenth
Street. The following cost breakdown is based on the assumption that we will have to wellpoint the
portion along East Coast Drive from Twelfth St. to Fifteenth St. and from East Coast Dr. down Fourteenth
St. to just east of Ocean Blvd. This assumption is based on our field obsen~ation from the test holes eve
dug on Oct. 26, 1999. From these observations I feel this would be the worst case scenario. The cost for
the wellpointing is inclusive of the additior_al asphalt and other right of wav restoration such as, grassing
and landscaping needed to restore the site to original condition. The folio«zng estimate is based on
w~ellpointing the entire length discussed above, however if conditions allow the installation of the pipe
without the need for wellpoints, our final invoice will reflect the actual quantity installed.
Estimated QuantitS~ 1250 lineal feet ~! $11.16 per lineal foot =51-1,37.00
We have installed all the services for this portion of the work and have cut the asphalt for the installation
of the main. Therefore, we need to proceed `pith this work as soon as possible to avoid any complaints
from the residents. Please notify us at your earliest com~enieuce.
Best Regards,

RE: Atlantic Beach Water Line Improvements
Dear Mr. Kosoy:
This letter is intended to serve as further justification for the change order regarding the need for
wellpointing the twelve inch water main on East Coast Drive. Gruhn May, Inc. has been the point
repair contractor for the City of Atlantic Beach for the past several years and as a result we have a
great deal of experience regarding the need for wellpointing in and around the area. We have also
been in underground utility business for the past 27 years. Our contention regarding the need for
wellpoints is that the area in questions differs substantially from the surrounding areas. We are
currently laying pipe on Beach Ave. and we are excavating in excess of five feet deep and are not
encountering ground water elevations as we are on East Coast Drive. Furthermore, we installed
the new pipe at 15`'' & Seminole Road without the need for wellpoints. These two areas are at
relatively the same elevation as East Coast Drive, however the groundwater on East Coast Drive
is only 18" below the surface. It is our contention that this area on East Coast Drive has
substantially differing site conditions from the other surrounding areas. In respect to differing site
conditions, it would be no different to request a change order for the removal of rock or clay or
any other unsuitable material that is not found in the immediate surrounding areas. We feel that
the need to wellpoint the entire line section along East Coast Drive is not something any
contractor should have or could have anticipated given the information and experience we
compiled over the past several years. My previous letter explained that we have included the cost
of wellpointing at other locations on this job, more specifically, tie-in locations, crossing under
existing utilities and other areas shown on the plans that will require a increased depth of bury. If
you have any further questions or I can be of further assistance I can be reached at 262-9544.
Best Regards,
Gordon Gruhn

Dear Mr. K~~soy:
At your request, we reviewed the Gotitracto~'s letters dated October 27, 1999 and November 2,
1999. The Contractor has asked for additional compensation due l~~ unli~r~cen uttdergrout~d l,i,gh
wale;r table nn Last C,'oast J7rive;. It is our opinion that the Contractor's request for additional
campensaticm is valid and reaSc~nahle and should be accepted by the City. "S"he fact that the water
table is signiticantly hit,;her than surraundinb areas and the Cuntra~;tor's cot~siderablc familiarity
with the subsurface conditions in Allanlic I~cach during preparation of his bid contributed strc~nLiy
to this gpinicm. I1't.his high water table nn East Coast drive had been known during the bidding
period the initial hies cast to the City would have been higher,
If we can answer any farther clucstions in this matter, dc~ not hesitate to contact us.
