About this file
This is a project control log and construction plan document for the Michigan Department of Transportation (MDOT) detailing roadway improvements on US-12 in the Village of Edwardsburg, Cass County, Michigan. The project encompasses Control Section 14041, which begins approximately 1,100 feet east of the US-12 and M-62 intersection. The scope of work includes traffic maintenance according to standard specifications, shoulder placement (Class II), guardrail installation (Type MGS-8 with 108-inch posts), guardrail approach terminals (Type 2M), and installation of reflectors and delineators. Work items include 5 cubic yards of Class II shoulder material, 350 feet of Type MGS-8 guardrail, 2 guardrail approach terminals, 16 guardrail reflectors, 2 green delineator reflectors, 2 rigid delineator posts, 40 channelizing devices (42-inch fluorescent), 4 lighted arrow panels (Type C), 480 square feet of temporary prismatic signage, and traffic regulation control services. The contractor must maintain access to all commercial, residential, and intersection areas throughout construction and is prohibited from disturbing existing wetlands; earth disturbance is limited to 10 feet beyond slope stake lines except in wetland-adjacent areas where disturbance is restricted to the slope stake line.
The document specifies detailed construction standards referencing MDOT Standard Specifications for Construction, Standard Plans, and Special Details. A comprehensive utilities contact list is provided identifying thirty utility companies and agencies with facilities in the project area, including ANR Pipeline, AT&T Communications, Consumers Energy, Enbridge Energy Partners, SEMCO Energy Gas Company, and municipal water, sanitary, and electrical providers; contractors must notify MISS DIG System, Inc. at least 3 working days prior to excavation per Michigan law. The plans include standard guardrail details (Types A, B, BD, T, TD, MGS-8, and MGS-8D) with specific post spacing, beam element configurations, and reflector placement requirements. Traffic control follows the Maintaining Traffic Typical 110-TR-NFW-2L standard, with channelizing device spacing, sign placement, and roll-ahead distances determined by posted speed limits. Restoration measures for approved disturbance areas are included in the plans, with costs for any work beyond approved areas and associated restoration becoming the contractor's responsibility upon submission and approval of an earth change plan.

GENERAL NOTES
UTILITIES
MISS DIG/UNDERGROUND UTILITY NOTIFICATION
Contact MISS DIG System, Inc. for the protection of underground utilities and in conformance with MCL 460.721 et seq, by phone at 811 or 800-482-7171 or via the web at http://www.missdig811.org/, a minimum of 3 working days prior to excavating, excluding weekends and holidays.
SURVEY
STATIONING
Stationing on this project was taken from old plans and is not necessarily accurate.
EARTH DISTURBANCE LIMITS
Limit earth disturbance to 10’ beyond the slope stake line or to the ROW line whichever is less except areas adjacent to wetlands where the limits of earth disturbance are at the slope stake line. The plans include restoration measures for the approved areas of disturbance. Submit an earth change plan to the Engineer to review and approve for any work beyond the approved areas of disturbance. Costs for obtaining and executing an approved earth change plan, including restoration are the Contractor’s responsibility.
GUARDRAIL
When the plans specify guardrail to be placed at the shoulder hinge point, rather than as specified on Standard Plan R-60 series, 8’ (type B or T) or 9’ (type MGS-8) posts shall be provided, with the additional length embedded for added stability. The additional post length will not be paid for separately but shall be included in the appropriate guardrail pay item.
