Location Length = 1.155 miles

DESCRIPTION OF WORK

The work shall consist of a 1.5” uniform cold mill and single course HMA overlay for the right lane and shoulder from the POB to the POE. At cross streets, the milling and resurfacing limits shall be defined as a straight line from curb face to curb face

Drainage structures and monument boxes within the resurfacing limits shall be plated or coated with a bond breaking agent prior to the placement of HMA, 5EMH.

Traffic will be maintained as described in the Maintaining Traffic section contained in this proposal.

ESTIMATED QUANTITIES

The quantities included in the summations below are approximate and for reference only. Contractor will be responsible for verifying quantities before bidding by site inspection and plan review. If any major discrepancies are noted, contractor must contact Scott Badger at (989) 280-4057.

This project is a Maintenance funded project, which means that there will be

C.S. 37011 J.N. 22-37003 absolutely no overpayment or extras. All material, labor and mobilization shall be included in the bid.

MDOT will have the low bid reviewed and approved for funding. MDOT reserves the right to reject any bid that appears to be unqualified. Before award, MDOT may request a site and plan review meeting with the low bid contractor.

MAINTAINING TRAFFIC

Traffic Restrictions

Maintaining traffic will be accomplished with traffic shifts and traffic regulators utilizing the following Maintaining Traffic Typicals

101-GEN-SPACING-CHARTS

102-GEN-NOTES

103-GEN-SIGN

104-GEN-AB

106-GEN-SPEED-NFW

123-NFW-1LC-(R)

Additionally, traffic shall be maintained according to Sections 104.07, 104.11, and 812 of the 2020 Standard Specifications for Construction, including any Supplemental Specifications, and as specified herein.

Access on side streets may need to be restricted, prohibiting turning movements during stages of construction on Mission Street to ensure the safety of workers and the motoring public. This will be allowed at the approval of the engineer. Additional quantities have been included to cover this work.

Sign covers shall be placed over any regulatory, warning, or construction signs that are not applicable during construction.

The Contractor shall not create any unsafe conditions within the Construction Influence Area (CIA) that form a hazard for motorists. The CIA shall extend as far as the required advanced construction signing, or any other signs pertaining to this location. Extra caution should be used when delineating the work zone overnight to protect the roadway users.

No work shall be performed, or lane closures allowed during the Labor Day holiday period. The Labor Day holiday period shall be defined as beginning on Friday, September 2nd through Tuesday, September 6th.

The Contractor shall maintain traffic on all intersecting driveways at all times.

Crossroads shall remain open to traffic at all times. Additional traffic regulators shall be used at unsignalized intersections and driveways, as directed by the Engineer. Payment for these items shall be included in the lump sum price for the project.

All lanes shall be flush with each other at the end of each workday.

C.S. 37011 J.N. 22-37003

Traffic will not be allowed on any cold milled surface other than for crossing.

Maintenance of the cold milled surface is the responsibility of the Contractor, and any costs associated with such maintenance shall be included in the lump sum price for the project.

No weekend work unless approved by the Engineer. Weekend work is defined as Friday through Sunday. All lanes and shoulders shall be open to traffic unless work is in progress which prohibits opening of lanes due to safety or other reasons approved by the Engineer.

Once work is initiated that includes any lane restrictions, that work shall be continuous until completed.

The storage restrictions in section 812.03.G.5 of the 2020 Standard Specifications for Construction will be strictly adhered to. The Contractor shall not park any vehicle or store any material on public recreational property.

Daily maintenance of traffic control items will not be paid for separately but will be included in the lump sum price for the project.

C.S. 37011 J.N. 22-37003

GENERAL NOTES

SPECIFICATIONS FOR CONSTRUCTION

The improvements covered by these plans shall be done in accordance with the MDOT 2020 Standard Specifications for Construction.

RECREATIONAL PROPERTIES

The Contractor shall not park any vehicles or store any equipment on public recreational property. Access to the recreational properties must also be maintained at all times.

Noncompliance, even without the knowledge and approval of MDOT personnel, can result in penalties up to and including termination of the construction contractor and loss of federal funding for the project. Should there be any questions regarding this requirement, contact the MDOT Environmental Section at (517) 373-8350.

MISS DIG/UNDERGROUND UTILITY NOTIFICATION

For the protection of underground utilities and in conformance with Public Act 174 of 2013, the Contractor shall contact MISS DIG System, Inc. by phone at 811 or 800-482- 7171 or via the web at either elocate.missdig.org for single address or rte.missdig.org, a minimum of 3 business days prior to excavating, excluding weekends and holidays.

ADJUSTING MONUMENT BOXES

All government corners on this project shall be preserved, whether shown or not. It may be necessary to place or adjust monument boxes, as required.

NOTES APPLYING TO STANDARD PLANS

Where the following items are called for on the plans, they are to be constructed according to the Standard Plan or Special Detail given below opposite each item unless otherwise indicated.
