Dear Ms. Fauteux:
Hayner/Swanson, Inc. (HSI) is pleased to submit this proposal to provide professional services
in our continuing support of the City of Nashua’s rehabilitation program of existing sewerage
pipe and structures. The work shall focus on planning, investigation, engineering and
construction administration related to the completion of the 2020-21 Program; and design
services for the 2022 Sewer Rehabilitation Program. We understand that the services we
provide will effectively be performed as an extension of the City Engineering Department.
HSI will work with City staff in a highly integrated effort. This effort will be similar to services
we are presently providing in support of the City’s on-going sewer rehabilitation program.
We are proud that this unique arrangement has proven to be successful on the 2019, 2020 and
the 2021 programs. This work has been performed with significant savings for the City and with
the burden of administration by City staff minimized.
We understand that the services to be provided on this program will be varied and will include
management, administration, sewer line video assessment, design and construction
observation. At times, we will be the lead for tasks. At other times, we will work in direct
support of City staff. Our commitment to flexibility and to consistent and clear communication
with the City will be the key to success on this program, as it was key on past projects.
We understand that our responsibilities may be adjusted by the City based upon the specific
needs and workload of the City staff. We anticipate that tasks which we will undertake include:
e Coordinate with City Staff regarding known sewer issues.
Review record information including videos, record plans, permits, and resident
complaints.
e Provide sewer line video review in support of the City’s on-going CIPP Sewer Lining
Program.
e Provide recommendations for the 2022 Program to line, repair or replace sewers and
structures.
e Identify and coordinate efforts to obtain additional information needed including survey
of inverts, condition assessments, and video investigation.
Provide utility coordination.
e Assist the City in prioritizing remedial efforts.
e Prepare plans, specifications and Opinion of Probable Cost (OPC) for the 2022 Sewer
Replacement Project.
e Provide assistance and coordination during the bid period, and prepare addenda, if
required.
e Provide support to the City in updating the City’s GIS data to reflect on-going progress.
