Model as Legal Document (MALD) Bridge Support

MnDOT Contract No. 1064034
Exhibit C: Specifications, Duties, and Scope of Work
1 Project Overview
The State is developing a pilot project utilizing Model as the Legal Document (MALD) for the delivery of a
bridge project. The State will produce the preliminary and final contract deliverables for the project. The
State's intent is to utilize Industry Foundation Classes (IFC) file format for the contract deliverable of modeled
portions of the bridge. The anticipated letting date for the project is September 27, 2028.
The bridge type is anticipated to be a multi-span, prestressed concrete I-girder bridge over water supported
on multi-column or pile bent piers and integral abutments.
The State anticipates using Bentley OpenBridge Modeler along with ProStructures/ProConcrete for
developing the IFC file(s). The State also anticipates using Bentley Infrastructure Cloud for assembling
contractual documents and creating Saved Views. Additional software may be used for modifying IFC files as
necessary.
The State anticipates contractual documents created for the project will be a combination of the IFC file(s)
and standard 2D plan details for items and details not shown in the 3D model.
The State requests a Contractor to provide modeling support and guidance for the first Bridge MALD in the
State of Minnesota.
2 Personnel Requirements
The Contractor's key personnel required to work on this contract include:
* Project Manager

delivering at least one project using the IFC format of MALD. At a minimum, the IFC model must have been
fully developed with QC/QA complete and ready for signature.
[Title] 1

MnDOT Contract No. 1064034
Exhibit C: Specifications, Duties, and Scope of Work
No substitutions of key personnel may be made without the prior written approval of the State Project
Manager. The State will notify the Contractor immediately if there are changes to the State's assigned project
management personnel.
3 Project Management
The point of contact for the State for technical aspects of the project will be the State's Project Manager or
his/her designee. All questions, submissions, and other correspondence must be directed to the State's
Project Manager. The Contractor and the State will exchange contact information for local coordination.
3.1 Project Management Team
The State has established a Project Management Team (PMT) that consists of both Bridge Office and District
staff representing different stages of the bridge process.
The Contractor will be responsible for the effective communication and coordination of the project to ensure
all the project tasks are completed on time, within budget, and in accordance with State and Federal laws,
rules and regulations.
A smaller Bridge Design Team (BDT) will consist of the Bridge Office members of the above PMT.
3.2 Project Meetings
This task includes a kick-off meeting at the Bridge Office in Oakdale, MN. Assume 2.5 hour duration.
The Contractor will attend virtual meetings with the State on an as-needed basis to answer modeling or BIM-
related questions during the Preliminary and Final Design phase of the project. For the work as defined in this
portion of the Contract, assume 6 meetings, 1.5 hours each.
The Contractor will meet with the BDT for a Model Review Meeting to discuss comments to the bridge model
after each model review deliverable as described in the scope below. Assume 2 hours per meeting to be
attended by the Contractor's Project Manager and Model Development Lead.
4 Technology Report
The Contractor will help evaluate software and hardware tools required for the State to produce the IFC
model deliverable and to consume it during construction/inspection. Initial conversation will happen at the
project kick-off meeting. After completion of the meeting, the Contractor will assemble a report
demonstrating software and hardware options and recommendations for software and hardware to be used
in development of contract deliverables and consumption of the contract deliverables by inspection/field
staff during construction. It is expected that the modeling will be completed in OpenBridge Modeler and
ProStructures/ProConcrete and assembled using Bentley Infrastructure Cloud, therefore the report should
focus on any supplemental software requirements and the value they provide to the project. The report must
consider State requirements for contracting with software vendors. Additionally, the report must consider
hardware needs for the recommended software and what, if any, additional hardware procurement will be
necessary by the State. Consider the technology needs for both the design and construction phase of the
project. Include connectivity needs for construction/field staff.
[Title] 2

MnDOT Contract No. 1064034
Exhibit C: Specifications, Duties, and Scope of Work

* Construction field staff support
The Training must be completed within 8 weeks of Notice to Proceed. It is assumed the training will consist of
12 hours of training, which will be split into 2 days, and may be held either virtually or in a hybrid
environment.
The Contractor will also assist with providing training to the State's construction staff on use of the model
during construction. This training will be performed upon completion of the model deliverables and prior to
beginning of construction. It is assumed the training will consist of 12 hours of training, which will be split
into 2 days and may be held either virtually or in a hybrid environment.
6 Level of Development (LOD) Workshop
The Contractor will participate in a workshop discussing LOD. The goal of the workshop is to develop a plan
for the level of detail to model each element of the bridge at both Preliminary and Final stages of the project.
The workshop will be scheduled within 6 weeks of Notice to Proceed to ensure Preliminary Design starts with
the appropriate LOD. The workshop is anticipated to be virtual for 4 hours. The State will supply a draft LOD
recommendation to the Contractor prior to the workshop. The Contractor will develop a final
recommendation of LOD for each state of the project as a result of this meeting. The LOD Recommendations
are due one week after the workshop.
7 Software Support
The Contractor will provide technical support answering questions from the State throughout development of
the construction deliverables. The support will be focused on modeling and MALD-related issues as they arise
in the project development. Assume 80 hours of technical support related activities.
