1
Are you anticipating storm sewer invert survey to be
included in the Task 3 (Existing Storm Sewer Capacity Analysis) scope?
Yes. The City expects to acquire invert data for storm sewer network
components. The City does not plan to collect invert data for the entire storm sewer network and will primarily focus on strategic assets and high-priority
areas. Various data collection methods may be used, including field surveys,
records review, and standard assumptions. The City will decide on the scale
of the data collection effort during the scope and budget stage of the Project.
2 Can you provide the most recent stormwater system
geodatabase?
Yes. The City has compiled a geodatabase comprised of storm sewer network
components. Please contact Kayla Mehrens at kmehrens@bozeman.net to
receive a data use waiver and a link for download.
3 In what format is the storm sewer NASSCO PACP data?
The City's CCTV equipment utilizes a proprietary software owned by CUES,
Inc. called GraniteNet. GraniteNet has two primary components: (1) A front-
end that provides a user interface for crews to input information, record
video, and complete scoring, and (2) a back-end comprised of a Microsoft SQL Server Database. The CCTV videos are stored as MPEG files.
4 Can you share the XP SWMM models that were completed
for the 2008 Facility Plan?
Yes. The City has compiled the 2008 Stormwater Facilities Plan model data.
This information has not been used or updated since its development. Please
email Kayla Mehrens at kmehrens@bozeman.net to receive a link for
download.

Was there any modeling completed for the storm sewer
rehab project in the W Mendenhall alley? If so, can you share those models?
Yes. The City is aware of two projects where a model exists: (1) Montana
Department of Transportation's (MDT) Rouse Reconstruction Project, which
replaced storm sewer infrastructure serving the roadway and upstream drainage basins. Respondents are encouraged to contact MDT for more
information regarding this project and available data. (2) The City's Storm
Sewer Rehabilitation Project, which is ongoing and seeks to rehabilitate
approximately 1,000 feet of historical storm main. A Consultant is under contract to complete Hydrologic and Hydraulic Analysis for a portion of the
storm sewer network upstream of the Project's location to determine the
rehabilitated pipe's hydraulic performance post-rehabilitation. Further, the
City has tasked the Consultant with completing an alternatives analysis to
identify opportunities to offset capacity shortfalls. The Rehabilitation Project's
model and associated deliverables are not available since the Project is
ongoing; however, a Stormwater Main Rehabilitation Alternatives Evaluation
specific to the Project is complete and now located in the document center
linked in the RFP. The City will make more information about this Project publicly available once complete; however, it expects the date to be after the
RFP submittal deadline.
6 Is the City firm on using Innovyze InfoSWMM to develop
an updated storm sewer model?
No. The RFP allows flexibility for alternate modeling approaches, so
respondents have the latitude to explain the advantages of using preferred
modeling platforms. The City will decide on the model's type and scale during the scope and budget stage of the Project.
7 Name change note. Should we use Kyle in our proposal or
Kayla?
The Project Manager listed on the RFP will be using the name Kayla Mehrens
on a go-forward basis, not Kyle Mehrens, as listed. The City apologizes for the
confusion and wants to assure respondents they are not required to change
or update any of their prepared documents. Inconsistencies will not impact the review of proposals in any way. Kayla Mehrens' email and phone numbers
will remain the same as listed.
