The Michigan Department of Transportation - Construction Manual (CM) contains MDOT clarification on policy, procedure and guidance for the construction of road and bridge infrastructfure and other related facilities. It also includes specific technical topics related to the divisions of the 2012 Standard Specifications for Construction (2012 SSFC). The information is presented in numerous articles having as simple a layout as possible. These articles are numbered to reflect as closely as possible the pay items and divisions from the 2012 SSFC.
The CM is not a contract document and CM articles are not referenced as "sections" but as CM XXX.XX.XX or "articles" to avoid confusion with MDOT specifications. Where a conflict exists between the CM and a contract, the contract document rules. References and links to the Michigan Standard Specifications are given as "Sec XXX.XX" or "Section XXX.XX of the 2012 Standard Specifications for Construction." References and links to the Michigan Standard Plans or Special Details are "Standard Plan R-##-A" or "Special Detail ##".
The CM articles are grouped into divisions and sections similar to the 2012 SSFC. The sections are then broken down into four (4) smaller sub-divisions similar to the 2012 SSFC. These are:
- General (Description)
- Measurement and Payment
The bulk of the information will typically be under the construction sub-division for each section.
To make revisions to the content a User (must be registered) can make a suggestion to the Content Manager for a particular division:
The Content Managers for the various divisions are:
The Content Managers will then assign to technical subject matter expert staff to discuss the merits of the suggested revision, make any supportive changes to the recommendation and update the content if deemed appropriate. Just because a user suggests a change does not mean that it will happen automatically, it will be vetted through appropriate review teams per the process appropriate for the type of change.
Type 1: Editorial changes only, Content Manager can make the change without review from technical experts.
Type 2: Slight technical change or impacts more than one division of the CM. This will be distributed by the Content Manager to an Ad Hoc team of technical area experts for review, discussion, approval and editing.
Type 3: Complex technical change, policy revision, or high cost. The Content Manager, will assemble an Ad Hoc team of technical area experts for review, discussion and drafting of a proposal to the Engineering Operation Committee (EOC). The EOC will then make a decision regarding implementation of the change in to the CM.
