construction phase services for the recommended improvements to the City of Paris Wastewater
Treatment Plant (WWTP) as detailed in the design documents as prepared by Garver under Amendment
1.
The designs developed underAmendment 1 were developed with the intention of being constructed under
two construction contracts: Construction Package 1 and Construction Package 2. The scope of services
for Amendment 2 includes only the construction phase services for Construction Package 1.
The planned improvements in Construction Package 1 include the modification and refurbishment of
existing facilities as well as construction of new facilities atthe existing WWTP to meet the targeted
capacity and treatment criteria for baseline improvements to the existing WWTP and to prepare for
Construction Package 2.
The improvements in Construction Package 1 include the rehabilitation, modification, or construction
of the following:
• Influent splitter box
• Primary clarifiers
• Primary sludge pump station
• Aeration basins, aeration basin blowers, and electrical building
• Mixed liquor splitter box
• Final clarifiers
• RASNVAS pump station
• Sludge dewatering building and equipment
• Recycle flow pump station
• Non -potable water pump station
• Sludge holding tanks and blowers
The project includes an associated array of piping enhancements and civil/yard enhancements,
together with electrical, instrumentation, and control enhancements to develop a complete and
functional facility capable of treating 7.25 MGD permitted design flow.
1. Construction Phase Services for Construction Package 1
1.1. Construction Administration
During the construction phase of work, Garver will accomplish the following:
• Issue a Notice to Proceed letter to the Contractor and attend preconstruction meeting.
• Prepare for and attend utilities coordination meeting.
• Attend progress/coordination meetings with the Owner/Contractor.
• Evaluate and respond to construction material submittals and shop drawings. Corrections or
comments made by Consultant on the shop drawings during this review will not relieve Contractor
from compliance with requirements of the drawings and specifications. The check will only be for
review of general conformance with the design concept of the project and general compliance with
the information given in the contract documents. The Contractor will be responsible for confirming
and correlating all quantities and dimensions, selecting fabrication processes and techniques of
construction, coordinating his work with that of all other trades, and performing his work in a safe
and satisfactory manner. Consultant's review shall not constitute approval of safety precautions
Appendix A - Scope of Services
Amendment 2 1 of 6 Version 3
City of Paris WWTP Improvements
or constitute approval of construction means, methods, techniques, sequences, procedures, or
assembly of various components. When certification of performance characteristics of materials,
systems or equipment is required by the Contract Documents, either directly or implied for a
complete and workable system, Consultant shall be entitled to rely upon such submittal or implied
certification to establish that the materials, systems or equipment will meet the performance
criteria required by the Contract Documents. Consultant will review up to 550 submittals.
• Issue instructions to the Contractor on behalf of the Owner and issue necessary clarifications
(respond to Request for Information (RFIs)) regarding the construction contract documents.
Consultant will respond to up to 300 RFIs.
• Review the Contractor's progress payment requests based on the actual quantities of contract
items completed and will make a recommendation to the Owner regarding making a monthly
partial payment. Consultant's recommendation for payment shall not be a representation that
Consultant has made exhaustive or continuous inspections to (1) check the quality or exact
quantities of the Work; (2) to review billings from Subcontractors and material suppliers to
substantiate the Contractor's right to payment; or (3) to ascertain how the Contractor has used
money previously paid to the Contractor.
• When authorized by the Owner, prepare up to ten (10) change orders for approved changes in
the work from that originally provided for in the construction contract documents. If redesign or
substantial engineering or surveying is required in the preparation of these change order
documents, the Owner will pay Consultant an additional fee to be agreed upon by the Owner and
Consultant.
• Conduct a classroom training session for operations staff for the new processes. This training will
provide operations staff normal operational strategies for the aeration basins and the belt filter
presses. This training will be up to 8 total hours in duration conducted across two consecutive
days and will be conducted by up to two Garver members. One digital (PDF) and one hard copy
of the classroom materials will be provided.
• Prepare and furnish record drawings.
• Participate in final project inspection, prepare punch list, review final project closing documents,
and submit final pay request.
1.2. Construction Observation
Resident construction observation services will be provided by Consultant's Resident Project
Representative(s) for the twenty-four (24) month (720 day) construction contract performance time. The
proposed fee is based on one (1) full time observer working approximately eight (8) hours per day, five
(5) days per week.
Construction observation services will be provided by Consultant's Resident Project Representative(s),
who will provide or accomplish the following:
• Consult with and advise the Owner during the construction period with significant changes/issues
during the construction period.
• Coordinate with the Owner's contracted firm that is providing construction materials quality
assurance testing under separate contract with the Owner.
• Maintain a file of quantities incorporated into the work, test reports, certifications, shop drawings
and submittals, and other appropriate information.
• Maintain a project diary which will contain information pertinent to each site visit.
In performing construction observation services, Consultant will endeavor to protect the Owner against
defects and deficiencies in the work of the Contractor(s); but Consultant cannot guarantee the
performance of the Contractor(s), nor be responsible for the actual supervision of construction operations
or for the safety measures that the Contractor(s) takes or should take. However, if at any time during
construction Consultant observes that the Contractor's work does not comply with the construction
Appendix A - Scope of Services
Amendment 2 2 of 6 Version 3
City of Paris WWTP Improvements
contract documents, Consultant will notify the Contractor of such non-compliance and instruct him to
correct the deficiency and/or stop work, as appropriate for the situation. Consultant will also record the
observance, the discussion, and the actions taken. If the Contractor continues without satisfactory
corrective action, Consultant will notify the Owner immediately, so that appropriate action under the
Owner's contract with the Contractor can be taken.
The proposed fee for construction services is based on a 720 -calendar -day construction contract
performance time. If the construction time to substantial completion extends beyond the time established
in this agreement, and the Owner wants Consultant to continue the applicable Construction Phase
Services, the Owner will pay Consultant an additional fee agreed to by the Owner and Consultant.
