and plan sheets must be independently checked and reconciled prior to submittal to State.
Review comments from State on Contractor's various plan review submittals does not relieve
Contractor of liability for an inaccurate or incomplete bridge plan. With each plan submittal,
Contractor must supply an electronic copy of plan and calculation check prints, along with a
comment log documenting resolution of all State plan review comments.
2.2 SOFTWARE PROGRAMS
Software programs and/or spreadsheets utilized by Contractor must be verified by Contractor's
in-house Quality Assurance Program.

3.7.1 30% Plan Review
The 30% Plan provides State an early review of the final plan preparation for conformance
with the signed Preliminary Plan, aesthetic guidelines, and key design specifications. The
intent of this review is to identify design discrepancies at an early stage and avoid major
plan modifications resulting from future reviews. At a minimum, the 30% Plan will include:
a) GP&E
For this submittal, the GP&E sheet(s) need to be completed only to the extent
necessary to show general dimensions, elevations, cross section, architectural
features, stage construction information, and basic design data. The sheet(s) will
3

MNDOT CONTRACT NO. 1063376 - 1063379
EXHIBIT A: SPECIFICATIONS, DUTIES, AND SCOPE OF WORK
be based on the approved Preliminary Plan.
b) Framing Plan
Include a preliminary beam run with computations.
c) Bridge Layout Sheet(s)
For this submittal, the Bridge Layout Sheet(s) must show a line diagram that
indicates the control point, work line, reference lines, and proposed working point
locations. The tabulations required do not need to be completely filled in;
however, the sheet(s) will indicate the diagonal and other dimensions that will be
included in the Final Plan. It will also contain any corner views sections, and
notations (i.e. expansion joint details at gutters, sidewalks, barriers, etc.) needed to
clarify the working point locations. Corner details may be detailed on a separate
sheet for clarity.
d) Abutment Layout Sheet(s)
For this submittal, the abutment layout sheet(s) need to be completed only to the
extent necessary to show footing size and the top/bottom elevations for
coordination with Final Road Design. It will also contain any tie-in points to adjacent
bridges, retaining walls, or both. Contractor will promptly coordinate any changes
in footing size, elevation, or both that occur between the 30% Plan and the 60%
Plan that would impact Final Road Design plans.
e) Architectural or Special Detail Sheet(s)
Architectural or special detail sheet(s) showing any standardized shapes proposed
to maximize repeatability of pier forms and other special details that require early
coordination between Contractor and State prior to final plan preparation.
f) Bridge Survey Sheet(s)
Survey sheets from the signed Preliminary Plan are to be included in this submittal;
however, they are not required to be completed.
g) Any supporting design computations used to develop the aforementioned items.
Contractor will submit two sets of the 30% Plan to State for review, along with an electronic
copy of the plan and calculation check prints. State will return 30% Plan comments to
Contractor within 20 working days. Contractor may proceed with further design during this
review period.
3.7.2 60% PLAN REVIEW
The intent of the 60% Plan Review is to verify Contractor's progress toward plan completion
and evaluate against project and contract timelines. The 60% Plan submittal will include two
full sets of in-progress plan sheets, working copies of electronic design files (MicroStation,
Geopak), and Draft Special Provisions. Include PC beam design, abutment details, and pier
design and details. State's Bridge Office will return 60% Plan review comments within 20
working days. Include an electronic copy of plan and calculation check prints, along with the
comment log documenting resolution of State plan review comments from the 30% review.

EXHIBIT A: SPECIFICATIONS, DUTIES, AND SCOPE OF WORK
Contractor may continue with design during this submittal.
3.7.3 95% PLAN REVIEW
The intent of the 95% Plan Review is for State to verify that the plan is acceptable for the
State Bridge Engineer's signature. The 95% Plan should be complete to the extent that it can
be certified by Contractor, although a certification signature is not required until after this
review has been completed. Contractor will submit the 95% Plan to State with the plan and
calculation check prints and comment log or other process documenting resolution of State
plan review comments from the 60% review. State's Bridge Office will return 95% Plan
review comments within 20 working days. Contractor will also submit finalized Special
Provisions (one electronic copy) with the 95% Plan submittal.

construction elevations for the bridge. Regardless of the software used, the output format
for construction elevations must be consistent with State's construction elevation program.
State will provide instructions and an example of construction elevations output upon
request. The construction elevations output must be submitted to State with the Final
Certified Bridge Plan.
3.7.5 FINAL CERTIFIED BRIDGE PLAN
Upon incorporation of State's 95% Plan comments, Contractor will submit the Certified Final
Bridge Plan to State for each bridge included in this contract.
4.0 LOAD RATINGS (SOURCE TYPE: 2850)
Contractor will provide a load rating analysis for each bridge and provide a Bridge Rating and Load
Posting report. Load rating work will be done in accordance with the AASHTO Manual for Bridge
Evaluation, current edition with interims.
Contractor will provide the load rating using AASHTOWare BrR software. Guidelines for
AASHTOWare BrR input requirements will be provided by State upon request. If the bridge cannot
be rated with AASHTOWare BrR, Contractor must use another commercially available structural
analysis software with the approval of State. The software must be capable of running overweight
vehicles as described below.
Contractor will load rate the bridge carrying vehicular traffic for Load and Resistance Factor Rating
(LRFR) using the following:
a) HL-93 loading
b) Minnesota Standard Permit Trucks G-80
c) Minnesota Standard Permit Trucks G-07, when a non-BrR (VIRTIS) software is used
5

MNDOT CONTRACT NO. 1063376 - 1063379
EXHIBIT A: SPECIFICATIONS, DUTIES, AND SCOPE OF WORK
The LRFR rating factor for new bridges must be a minimum of 1.0 at the Inventory level for HL-93
loading and 1.15 at the Operating level for permit loading. Contractor must demonstrate that the
minimum rating factors are being provided during the design of the bridge. For bridges with a
minimum of one span over 200 feet long, the permit vehicle loading must consist of a combination
of the permit vehicle and lane load. The lane load must be in accordance with Article 3.6.1.2.4 of the
AASHTO LRFD Bridge Design Specifications, except that the load will be 0.20 klf.
Contractor will rate the deck for any design that deviates from MnDOT standard design tables. Rate
and report each separate superstructure component, segment, or type within the overall bridge; at
a minimum, rate for moment and shear at the tenth points of each span. The overall rating must be
the lowest rating of any individual component, segment, or type. The final rating and each
component rating must be accompanied by the location of the rating, the limit state, and the impact
factor. Where ramps extend onto a bridge, rate the ramp as a separate member. For culverts,
complete MnDOT Form 90.
4.1 CONTRACTOR DELIVERABLES
a) Bridge Rating and Load Posting Report. The AASHTOWare BrR software file or the file from
another commercially available software must be submitted with the Bridge Rating and Load
Posting Report. The ratings must be based on the final configuration of the bridge.
b) Contractor will submit a preliminary rating with the 60% bridge plans.
c) Contractor will submit the final load rating and load posting report with the final certified bridge
plans.
5.0 APPROACH PANEL DESIGN AND DETAILING (SOURCE TYPE: 1250)
For bridge approach panels, Contractor will:
a) Choose and modify the appropriate standard plan sheets necessary for the
bridge approach panels (http://standardplans.dot.state.mn.us/StdPlan.aspx)
