Design of Northern Human Services Center to Include Work on Septic System

Proposal from Coulter Jewel Thames Paul Thames., 919-245-2303
Pam Jones, 919-245-2650
PURPOSE: To consider authorizing a change order for the design work associated with the
Northern Park to include completion of the design of the septic system that will support the Park
and the adjacent Northern Human Services Center.
BACKGROUND: The septic system project at the Northern Human Services Center has been
in process for several years, pending property acquisition to expand the system, regulatory
approvals from the State and County and completion of the design. Although the County
Engineer has prepared a conceptual and process design for the Northern Human Services
Center septic system, oversight of the construction of the recently completed Buckhorn sewer
and the work toward planning construction of the system that will serve the downtown Efland
area have prevented the completion of the specifications and drawings for the Northern Human
Services Center system in a timely manner. Since the septic system will support both the
Northern Park (the beginning of construction is imminent), as well as expanded usages of the
Northern Human Services Center, the need to complete the design construction documents,
final permitting and construction of the septic system is critical.
Coulter Jewell Thames (no relation to the County Engineer Paul Thames) is designer for the
Northern Park Project. The.design work being proposed is consistent with work the firm would
normally perform on the park project and it is therefore recommended that the design of the
septic system be added as a change order to the existing contract for park design.
The specific work that would be included in the change order, as detailed on the attached
proposal, is summarized as follows:
• Design of Grinder Lift Station
• Design of the Effluent Lift Station
• Drafting assistance to support the County's design efforts for the remaining portions of
the project.
a
® Prepare final site plan
Assist in the preparation of the project operation & Maintenance manual for the system
Coulter Jewell Thames estimated completion time needed for the drafting/design work and
submittal for final permit approval is four months, for permit approval is two months, and for
bidding and construction is six months. The County will require Coulter Jewell Thames to
provide bi-monthly updates regarding the status of this project in order to stay abreast of the
progress and to place the County in a position to provide assistance should the project be
delayed during the permitting process.
FINANCIAL IMPACT: The Board is asked to approve a change order for this work not to
exceed $74,500. Approximately $27,000 of that amount is attributable to work on the site plan
and the project Operation & Maintenance manual, both of which may be accommodated through
the County Engineer's office with assistance from the Environmental Health Division of the
Orange County Health Department. The consultant will provide an updated construction cost
as part of the work. Project funds from the County's 2004 Net Debt Reduction Bonds fund the
construction of the system. Although the work would be accomplished via a change order to the
Northern Park Project design contract with Coulter Jewell Thames, the design and construction
costs for the system would be charged to the septic system project account.
RECOMMENDATION(S): The Manager recommends that the Board approve a change order
for additional services in the amount not to exceed $74,500 for the Northern Park design project
to include the drafting/design of the new wastewater treatment system as outlined above; and
authorize the Chair to sign on behalf of the Board.

For Cir•il Engineering Consulting Serrices
To assist Orange County with the design of an on-site sanitary seta-er treatment system to sense die Northern
Human Services Center located north of Nilisborou~h nn 1\:C SCi.
Ucscription
This praposal is fir Civil Engineering sen~ices related to the design and drafting of various components a!''a
sanitary server treatment system to serve the Narthern 1-luman Services Ce.nter.yOran~e County has
developed a conceptual and process design for the septic system. The major components of the new sewer
s}•ste+n includes a grinder sewage lift station and force main to pump sewage co the new treatment. Iacility to
be located on the east. side of NC 4h, a sewer treatment facility, an effluent lift statian, and riitrificatian. fields
This proposal is for Coulter Jewel( Thames to design specific pumping and piping components of the overall
s_ystean and to provide drafting and other assistance for other portions of the project performed by Orange
County. Design work performed by Coulter Jewell Thames P.A. will include engineering drawings and
technical specifiratians for assembly by Orange County into the Contract Documents. Coulter Jewell
Thames will assemble or assist with assembly of the. b'td package and contract documen s as directed by
Oran~~e County. tt is understood that this "Agreement" holds harmless Coultec Jewell Thames, P.,a. of any
responsibility relative to the process and treatment of water-water being performed by the on-sste sanitary
sewer treatment faciiit;~ that ta~ill serve the l~torthern Husnan Services Center. Process design and associated
kinetics and the quality oftreatment of the tt~astewater for the Northe+-n Hutrian Services Center will he the
sole responsibility of Orange County.
