STRUCTURES MANUAL

Volume I — Administration and Procedures PREFACE

The Montana Structures Manual has been developed to provide uniform structural design practices for Department and consultant personnel preparing contract plans for Department projects. The bridge designer should attempt to meet all criteria presented in the Manual. However, the Manual should not be considered a "standard" which must be met regardless of impacts.

The Manual presents much of the information normally required for a structural project; however, it is impossible to address every situation which the bridge designer will encounter. Therefore, designers must exercise good judgment on individual projects and, frequently, they must be innovative in their approach to structural design. This may require, for example, additional research into the structural design literature.

The Montana Structures Manual was developed by the MDT Bridge Design Section. The Manual Review Committee consisted of:

Bob Modrow (Project Coordinator) Bryan Miller Jeff Olsen Kevin McCray Devin Roberts Dave Johnson Nigel Mends

i MONTANA STRUCTURES MANUAL (Revision Process)

All revisions to the Montana Structures Manual will be submitted and reviewed according to the following process:

Revision and Review

1. All proposed revisions should be submitted to the Bridge Design Engineer. The Revision Request Form (next page) should be used for the submittal.

2. A four-person Review Committee, selected by the Bridge Design Engineer, will meet every three months, or as necessary, to review the proposed changes.

3. The Committee will submit their recommendations and will meet with the Bridge Design Engineer to determine if the proposed revisions should be incorporated into the Manual.

4. If the revisions represent a policy change, the revisions will be presented to the District Administrators for comment.

5. If the Manual will be revised as recommended, a memo describing the revision will be distributed by the Bridge Design Engineer. The revised pages of the Manual will be attached to the memo and will be sent to all Manual holders.

Review Committee

The Review Committee will consist of four members. One member will be replaced each year; therefore, no one will serve on the Committee for more than four consecutive years. Individuals may serve on the Committee more than once.

In addition to the review of proposed revisions, the Committee will be responsible for the following:

1. providing all updates for the Structures Manual, 2. maintaining a comprehensive list of all Manual holders, and

3. maintaining a library of all revisions to the Manual in chronological order.

The basic objective of the PMS is to schedule, monitor and coordinate project development and manpower needs within the multiple-project environment of preconstruction. The PMS is a mainframe system which is augmented by several Oracle-based systems. These systems interface with other Departmental systems and provide data pertinent to projects in the preconstruction phases.

2. Construction Management System (CMS). The CMS is designed to plan and schedule the Department’s construction engineering manpower to effectively fulfill Department responsibilities for its program of construction projects. The CMS is a PC- based system which interfaces with other Departmental systems and provides data pertinent to projects in the construction phase.

The following describes the coordination between the Bridge Bureau and local governments:

1. Design. The Bridge Bureau solicits input from the local government on bridge design projects in that locality and, in general, keeps the local governments up-to-date on any current or planned activities.

2. Coordination. The Bridge Bureau typically invites the local government to any field reviews and provides the local government with copies of major project reports (e.g., Scope of Work Report).

3. Assistance. The Bridge Bureau provides technical assistance to the city and county governments, upon request. The Bridge Bureau responds to any verbal or written inquiries from local governments on bridge design issues. April 2004 ADMINISTRATIVE POLICIES AND PROCEDURES 4.1(61)

Bridge Replacement with no added capacity

Type Description 210 New Bridge Construction of a new bridge, which does not replace or relocate an existing bridge. 220 Bridge Replacement with added capacity The total replacement of a structurally deficient, or functionally obsolete bridge with a new bridge in the same general traffic corridor. The replacement bridge is designed for an increased traffic flow by accommodation additional through lanes. Construction of a dual structure to alleviate a capacity deficiency is also included. The new bridge carries all of the through traffic with the old bridge retained for local service only, removed, closed or converted to a purpose other than carrying through traffic. 221 The total replacement of a structurally deficient or functionally obsolete bridge with a new bridge in the same general traffic corridor. The replacement bridge is not designed for capacity over the previous facility. The new bridge carries all of the through traffic with the old bridge retained for local service only, removed, closed or converted to a purpose other than carrying through traffic. 222 Bridge Replacement with a culvert with no added capacity The structurally deficient or functionally obsolete bridge is replaced by a culvert that accommodates the same number of lanes as the replaced bridge. The old bridge is retained for local service only, removed, closed or converted to a purpose other than carrying through traffic. 223 Bridge Replacement with a culvert while adding capacity The structurally deficient, or functionally obsolete bridge, is replaced by a culvert with adequate length to accommodate additional through lanes. The old bridge is retained for local service only, removed, closed or converted to a purpose other than carrying through traffic. 230 Bridge Rehabilitation with added capacity Major bridge rehabilitation to restore the structural integrity of a bridge as well as work necessary to correct major safety defects. Bridge deck replacement (both partial and complete) and the widening of bridges by widening lanes or adding lanes are included. Construction of a dual structure to alleviate a capacity deficiency is also included when the old structure is included in the dual structure. 231 Major Bridge Rehabilitation without added capacity The major work required to restore the structural integrity, do a seismic retrofit, or correct major safety defects. Bridge deck replacement (both partial and complete) is included 232 Minor Bridge Rehabilitation Work required to correct minor structure and safety defect of deficiencies, such as deck patching, deck resurfacing, deck protective systems, upgrading railings, curbs and gutters, and other minor bridge work.

PROJECT WORK TYPES Figure 4.1B 1. Proposed Scope of Work. This section should provide a very brief description of the proposed scope of work for the project. For example, "The proposed project has been nominated to replace the existing 24 ft (7.2 m) wide bridge over the Madison River on US Highway 287 in Ennis. The new bridge will be constructed on a new alignment." The scope should indicate whether the project is a new structure, replacement structure or rehabilitated structure. The scope of work section should also include a brief discussion explaining the reason why the proposed scope of work was selected. If it is determined that an outside consultant should be considered for the design of the project, indicate the division of expected responsibilities between MDT and the consultant.
