5.3 BIM Management

The BIM teams shall maximize BIM capability to meet project goals. BIM managers will attend project kick‐off meetings to understand MDOT MAA project goals and the scope of work. BIM Managers will then interpret these into BIM requirements and uses for the project to define the necessary members of the project BIM team. The BIM team will manage model development, submissions of the models, and documentation throughout the project phases. The Design BIM Manager has the responsibility for the design BIM Execution Plan (BxP).

The consultant and contractor shall designate a BIM Manager responsible for BIM execution per the project scope of work (SOW). Team member roles are shown visually in Figure 5.3-1 and described in Table 5.3-1. Additional team members shall be assigned accordingly per the SOW, BIM Uses, and project complexity.

TABLE 5.3-1: BIM ROLES and RESPONSIBILITIES
MDOT MAA PM	MDOT MAA PROJECT MANAGER – is the MDOT MAA representative with project management and oversight responsibilities on behalf of the MDOT MAA.

QA-QC – Model Management A separate team member may be designated as QA/QC task coordinator supporting the As-built model, data checking, model integration, and other multi-disciplinary activities. Reports to the Construction BIM Manager.

The BIM Manager shall have an in-depth technical knowledge of Revit modeling and structure, project delivery, and BIM processes. They can manage teams and convey instructions to designers and other modelers. BIM Managers shall have experience interpreting what BIM uses to meet project goals for the BxP creation and updates for the project. BIM Managers:

C. Manage model creation and review across discipline teams or trades during construction

K. Develop submission packages for design or construction handover to MDOT MAA and other parties

BIM teams require multiple areas of expertise. Discipline modelers are trained professionals in the discipline combined with BIM expertise. BIM Use modelers have additional software expertise that makes use of the Revit model.

F. Fabrication modelers can utilize design intent models for fabrication through Revit or other fabrication software

G. BIM Use modelers use the model for analysis, rendering, animation, or other required uses beyond Revit capabilities

The MDOT MAA BIM Manager will work with the design team to define project BIM Uses and the model development strategy based upon MDOT MAA standards to achieve project goals. The BIM team must be aware of the downstream contractor, and MDOT MAA BIM uses to develop their model/s accordingly.

A. The MDOT MAA BIM Manager shall attend regular project review meetings and facilitate model uses to support MDOT MAA decision processes.

B. Regular BIM team meetings will be held to maintain the modeling schedule, model coordination, and quality control.

Projects have different characteristics based upon scope, contract type, project type, assets, and type of construction, which illustrates why a common BIM package for all MDOT MAA projects is not possible. The BxP identifies and documents the model uses on the project, its structure, and responsible parties. It details the schedule for BIM development, LOD progression, model coordination activities, model structure, and required asset data. The BxP is a deliverable per Section 5.4, Table 5.4-1. The BxP provides the following information:

F. BIM data requirements including additions to the MDOT MAA data naming conventions for new instances

A. MDOT MAA BxP_Template 1 – can be used for all size projects; composed of 2 separate files as follows:

Consultants shall confirm with the MDOT MAA BIM Manager, which template to use based on the complexity of the project.

The BxP documents the technical coordination of the model across teams. BxP development has two stages: the Design BxP and the Construction Phase BxP. Consultants and contractors must submit a BxP for their phase of the project for approval. The Design BxP is a contract deliverable as per Section 5.4, Table 5.4-1. As a contract deliverable, it provides documentation about the project BIM use and is a tool supporting post-project model use.

On DBB projects, the Design BxP is provided to the contractor. The contractor builds upon the Design BxP by adding additional information for the construction phase, which becomes the Construction Phase BxP.

On CMAR projects, the consultant and CM team jointly prepare the BxP. This combined plan is also called a Project Execution Plan (PxP).

BIM Uses identify modeling tasks for the project, responsible parties, LOD, referenced standards, and the desired outcomes. BIM Uses are defined in the BxP for the design and construction phases. Below is a table of MDOT MAA recognized BIM Uses. Others may be added to the BxP.
