Exhibit A
Oak Street Improvements
Scope of Work – Front Street Pathway
Revised 8/9/16
Sanderson Stewart is pleased to provide this scope of work for the Front Street Pathway as an amendment to
the existing Oak Street Improvements contract. We understand the project generally includes survey, design,
permitting, and construction administration for an asphalt pathway extending east from the Oak Street/Rouse
Avenue intersection along Birch Street and the Front Street right-of-way and ending at Wallace Avenue for a
total length of approximately 1250 lineal feet. The project includes a bridge across Bozeman Creek and
sidewalk along Wallace Avenue will be extended to connect to the existing Story Mill Spur trail. A detailed list
of assumptions and scope of services for the project are outlined below.
Assumptions:
1. KLJ is currently working on the Wallace Avenue improvements, which will overlap with the improvements
on the east end of this project. We will coordinate with them as needed throughout the design process,
but we understand that KLJ will design the realignment of the Kenyon Noble approach to Wallace as well
as the ADA accessibility ramps and crosswalk for the trail crossing on the north side of the approach. They
will also design the railroad crossing and Sanderson Stewart will design the additional sidewalk/trail to
make the connection between the north side of the railroad crossing and the Story Mill Spur Trail.
2. The bridge across Bozeman Creek will be prefabricated by Contech (or an approved equal) and it will be
acceptable to work with Contech engineers during the design phase. As sub-consultants to Sanderson
Stewart, STE Engineering will complete the structural design of the bridge foundation and Terracon will
complete the required geotechnical analysis.
3. Based on correspondence with Brian Heaston from the City of Bozeman, we understand that the proposed
Front Street pedestrian bridge will need to be permitted based on the draft new floodplain maps for
Bozeman Creek. The draft floodplain maps are currently under QA/QC review by FEMA and are
expected to be available within the next couple of months to be used as “Best Available Data”. The new
floodway width at the proposed bridge crossing is approximately 65 feet wide based on the draft mapping.
If a floodway encroachment analysis determines that the new bridge crossing does not encroach upon the
floodway, a conditional letter of map amendment (CLOMR) is not required prior to construction; however,
a letter of map revision (LOMR) will likely be required after construction. We have assumed that the
floodway encroachment analysis determines that the bridge crossing will not encroach upon the floodway
in order to avoid the CLOMR process and simplify the floodplain permitting prior to construction.
4. After construction, a LOMR will be required. Based on correspondence with Brian Heaston, we
understand the LOMR would be based on the draft new floodplain maps for Bozeman Creek (not the
current effective floodplain maps).
Scope of Work:
Sanderson Stewart will provide the following services as part of its basic services:
Phase 1 - Project Initiation
This phase of the project will include project initiation and planning tasks, including scoping, contract
preparation, meetings with the City of Bozeman and coordination with sub-consultants. All project
management tasks, client meetings and sub-consultant coordination for tasks beyond project initiation will be
allocated to the remaining project phases.
Phase 2 - Topographic Survey and Base Mapping
A detailed topographic survey of the pathway alignment will be conducted, including pre-survey research of
the property boundary and control information, setting control as needed, and a corner search to establish
right-of-way. Base drawings will be prepared/updated in Autocad format following the completion of the
topographic survey, and additional pick-up topo will be conducted as needed throughout the duration of the
project. Public and private utilities will be located prior to the survey via one-call for inclusion in base drawings.
The topographic survey phase will also include up to eight (8) cross sections across Bozeman Creek for the
bridge design and hydraulic modeling for the LOMR. This assumes we can tie -in to cross section L (4766)
upstream and cross section 4023 downstream on the draft new floodplain map. We will prepare a survey base
map to be used for the floodplain permitting, hydraulic modeling, floodway encroachment analysis and LOMR.
We will also survey the as-built location of the bridge after construction to be used for the LOMR.
Phase 3 - Floodplain Permitting and LOMR
This phase consists of preparing the necessary floodplain permit documents for submittal to the City of
Bozeman and preparation of the hydraulic models that are required by FEMA for their review of the LOMR.
We will utilize the draft study data flow information provided by FEMA for the 10-year, 50-year, 100-year, and
500-year peak discharges. The LOMR will be based on the draft new floodplain maps and not the current
effective floodplain maps. This phase also consists of preparing the LOMR application (MT-2 application) for
review and approval by FEMA for the new bridge. This phase of the project includes the following tasks:
Preliminary hydraulic modeling of bridge crossing to verify bridge span width and deck height based
on the new draft floodplain maps. We understand that an encroachment analysis will be required to
show that the bridge crossing does not encroach upon the floodway.
Prepare Joint Application for Permitting in Montana Streams.
Prepare Floodplain Exhibit showing floodplain fringe and floodway boundary and location of new
bridge.
Provide details of bridge and abutment and abutment scour protection. STE Engineering will be the
structural engineering sub-consultant for design of the bridge foundation and we have assumed that
Contech would provide details for the bridge deck.
Prepare City of Bozeman Stormwater Management Permit Application.
Submit permit information to the City of Bozeman for review.
We will also submit the Joint Application to the appropriate agencies for the 404 permit and 318
authorization to determine if these permits are required as well and will obtain these permits if deemed
required by the jurisdictional agency.
Review draft new floodplain mapping and modeling.
Prepare Duplicate Effective Model by importing the cross sections from the draft hydraulic model
from FEMA into the Hec-RAS Version 4.1 hydraulic model.
Prepare Corrected Effective Model/Pre-Project Conditions model.
Prepare Post-Project Conditions Model to include the new bridge. This model will need to tie-in to
the draft new floodplain at a published FEMA cross section within the tolerances allowed by FEMA.
We have assumed that we can tie-in to cross section L (4766) upstream and cross section 4023
downstream on the draft new FIRM map.
Prepare output tables and figures from hydraulic modeling in spreadsheet format to compare changes
from the draft model to the new model.
Prepare certified topographic map with floodplain and floodway delineations including transitions back
to the draft floodplain boundary.
Prepare annotated FIRM map showing changes in the floodplain.
Prepare project narrative summarizing the work done on the project.
Prepare MT-2 application form.
Submit MT-2 (LOMR) application to City of Bozeman and FEMA.
Once the LOMR application has been submitted to the City of Bozeman and FEMA, we will be available to
answer questions they have about the project and the LOMR application. We have assumed up to five separate
teleconference calls with the City of Bozeman or FEMA to discuss the project.
Assuming there will be review comments from FEMA, we have included one re-submittal of the revised LOMR
application materials to address their comments.
Phase 4 – Preliminary Wetland Review
A preliminary wetland assessment will be conducted by Hyalite Environmental to determine whether impacts
to wetlands would occur as a result of the proposed bridge design across Bozeman Creek. The remainder of
this scope is based on the assumption that a full wetland delineation and associated permitting will not be
required. If it is determined that a wetland delineation is needed, Sanderson Stewart can provide these services
as additional services.
Phase 5 - Geotechnical Analysis
Soils and pavement design evaluations will be conducted and recommendations for the pathway surfacing
section and bridge abutment design will be prepared by Terracon. Three soil borings will be drilled for this
project: one on either side of Bozeman Creek for the bridge design and a third near the Kenyon Noble lumber
yard to determine the asphalt pavement section. Terracon will prepare a geotechnical report summarizing their
findings that will be submitted with the preliminary plans.
Phase 6 – Pathway Design
Pathway design tasks for this phase of the project will include setting the horizontal and vertical alignment of
the pathway and preparation of plan/profile sheets and cross-sections. It will also include design of the sidewalk
extension along Wallace Avenue north of the railroad crossing for connection to the Story Mill Spur Trail. The
pathway design phase will also include coordination with the Wallace Avenue improvements project currently
underway by KLJ. As needed, the pathway design will include preparation of signing and striping plans,
sidewalk, crosswalks and ADA accessibility ramp design, and design details. Public and private utilities will be
shown for coordination and identification of conflicts.
Phase 7 –Preliminary PS&E Submittal
All of the above information will be compiled into a preliminary set of plans, specifications and opinion of
probable cost for review by the City of Bozeman and GVLT. Plans will include plan/profile sheets, cross-
sections, typical sections, signing and striping plans, an erosion control plan and details. Sanderson Stewart will
prepare special provisions and a specifications manual including the templates for bid documents. The
engineer’s opinion of probable cost including a 15% contingency will also be provided with this review
submittal. Landscape and irrigation plans are not included in this scope of work.
Phase 8 – Final PS&E Submittal
Sanderson Stewart will address all review comments received from the City of Bozeman and prepare final plans,
specifications and engineer’s opinion of probable cost. The final deliverable will include electronic copies of
all submittal documents, as well as six hard copies.
Phase 9 – Construction Bidding
Sanderson Stewart will provide assistance throughout the construction bidding process. Anticipated tasks
include the following:
Prepare bid advertisement
Prepare bid sets of plans and project manual for contractor pick up
Facilitate pre-bid meeting and distribute meeting minutes
Answer contractor questions and prepare bid addenda, as required
Attend bid opening, prepare bid tabulation and recommendation of award letter
Prepare six copies of contract documents, obtain bonding and insurance certificates, and route
contracts for execution by all parties
Phase 10 – Construction Administration and Observation
Sanderson Stewart will provide construction administration and observation services throughout the duration
of construction. Anticipated tasks include:
Facilitate pre-construction meeting and distribute meeting minutes
Shop drawing review
Construction observation (anticipated to be part-time for a 30-day construction contract focused
primarily on milestone tasks)
Construction testing coordination and review. Testing will be completed by a qualified sub-consultant
and is anticipated to include: concrete strength, air content and slump; embankment, trench backfill,
and gravel and pavement densities; aggregate gradations; plant mix strength, flow and asphalt content.
Process pay applications and change orders
Substantial completion walkthrough and punch list, verify completion
Prepare as-built drawings
Two-year warranty inspection and punch list
The Scope of Work for this project does not include:
Landscape and irrigation plans.
SWPPP permit application/administration.
LOMR based on the current effective floodplain maps.
Additional cross sections or hydraulic modeling that may be required to tie-in to the draft floodplain
maps upstream of cross section L (4766) upstream and cross section 4023 downstream.
Individual permit from the Army Corps for the 404 permit if disturbance of wetlands is greater 0.1
acres.
Cash fees for review and applications (by Client direct to agencies). The estimated LOMR
application fee to FEMA is $8,250.
