RED FLAG CHECKLIST
Complete this checklist for projects that do not go through the MnDOT scoping process or were scoped
prior to March 2015. For projects currently being scoped, complete the TMP Scoping Worksheet,
which includes the Red Flag Checklist, Work Zone Impact Assessment Worksheet, and TMP Scoping
Conclusions).

1. Is the existing shoulder in
good enough condition to
support traffic during
construction?
2. Could temporary structures
and/or additional width be
needed on culverts, bridges or
shoulders to maintain traffic
on the existing route or a
detour route?
3. Is there a pedestrian/bicycle
path, trail, or access that
needs to be maintained
during construction?
4. Will a Temporary Pedestrian
Access Route (TPAR) be
required (route meets ADA
and PROWAG standards)?
5. Are there critical features or
services on the route that
need to be considered (e.g.
hospital, emergency services,
transit, school buses)?
6. Could crossovers be needed?
7. Are there any issues
regarding construction
timeframes (e.g. time of day,
time of year limits, major
events, permits, bird nesting,
fish spawning, high water)?

8. Could there be a need to
maintain railroad traffic?
9.
Might temporary traffic signals be
required?
10. Does it appear that
maintenance of traffic will
require additional right-ofway?
11. Will/Can the traffic be
detoured?
If yes, list proposed
routes and answer the
following:
a. Is the local alternate detour
route in good condition?
b.
c.
d.
e.
Will the detour route have
a detrimental impact on
emergency vehicles, school
buses, or other sensitive
traffic?
Are there bridge/culvert
width or height restrictions
on the detour?
Are there issues regarding
the suitability of the detour
route (load limit
restrictions, length, speed
limit, travel time, etc)?
Are modifications needed at
intersections on
detour/alternate routes?
12. Could construction have
business impacts that could
affect project staging and/or
require mitigation?
13. Could Intelligent Work Zone
(IWZ) devices be needed to
mitigate traffic impacts?

14. Could moveable barrier be
needed/desirable to mitigate
traffic impacts or for
constructibility?
15. Are there other projects in the
area that should be
coordinated or avoided?
16. Are there geotechnical issues
(poor soils, contaminated
material, etc) that may affect
construction?
17. Are there utility issues that
may affect construction
staging?
18. Is the delay to traffic
anticipated to be greater than
10 minutes?
19. Could the project benefit from
innovative contracting (if Yes,
contact OCIC to schedule a
procurement method selection
meeting)?

Consideration of Accelerated Bridge Construction (ABC) Techniques

if multiple bridges with different staging complexity are included in project).

20. Is it likely that this project will
include complex traffic control
schemes, long detours, or
significant user impacts due to
bridge construction?
21. Is it likely that this project will
have an extended duration (more
than one construction season, or
extend into late fall) due to bridge
construction?
22. Is bridge construction on the
critical path of this project?
23. Does the existing bridge have
features that make it difficult to
accommodate staging (truss
bridge, slab span, beam spacing
issues, etc)?
24. Are there significant risks or other
factors (site complexity) that
could be mitigated by accelerating
bridge construction?
ABC Consideration Conclusion**:
Based on the findings & comments above, further consideration of accelerated bridge construction is warranted:
YES
NO
Project Manager Name: ___________________________ Date: ___________
If further consideration is warranted the Project Manager should contact the Bridge Office Preliminary Plans Unit
and the Regional Bridge Construction Engineer for assistance in selecting appropriate ABC alternatives and
techniques.
