BIM Standard Form of Contract:
Internationally, several standard contract forms have been developed to address BIM projects. Here are a few notable examples:
CIC BIM Special Conditions of Contract: Developed by the Construction Industry Council (CIC) in Hong Kong, this contract aligns with ISO 19650 and includes detailed provisions for BIM management, responsibilities, and model uses. AIA Document E202 - BIM Protocol Exhibit: Published by The American Institute of Architects (AIA), this document provides a BIM protocol exhibit that can be included in construction contracts to address legal issues related to BIM. ConsensusDOCS 301 - BIM Addendum: Created by ConsensusDOCS, this addendum is designed to be added to existing contracts to cover BIM-specific requirements and responsibilities. CIC BIM Protocol: Used in the United Kingdom, this protocol outlines the legal and contractual framework for BIM projects, ensuring clear definitions and responsibilities for all parties involved. In Malaysia, CIDB Standard Form of Contract for Building Works.
This form has been updating to include provisions specific to BIM projects, ensuring that all parties involved understand their responsibilities related to digital data management, model sharing, and collaboration

The BIM forms of contract:
The most common forms of contracts used for BIM projects are:
Design-Bid-Build (DBB): This traditional contract type involves separate contracts for design and construction. The design is completed first, followed by a bidding process for construction. While this method is widely used, it may not fully leverage the collaborative potential of BIM. Design-Build (DB): In this approach, a single entity is responsible for both design and construction. This can enhance collaboration and efficiency, as BIM models are used throughout the entire project lifecycle. Integrated Project Delivery (IPD): This contract type fosters a high level of collaboration among all project participants from the early stages of the project. It encourages the use of BIM for better coordination and integration of all project aspects. Public-Private Partnerships (PPP): These contracts involve collaboration between public and private sectors for infrastructure projects. BIM can be used to enhance communication and project management in these partnerships. Each of these contract types can be adapted to incorporate BIM methodologies, but the level of integration and collaboration may vary depending on the contract type chosen.
BIM Contract Documents
Building Information Modeling (BIM) contract documents are essential for managing and executing construction projects using BIM technology. These documents typically include:
BIM Execution Plan: This outlines how BIM will be used throughout the project, including model sharing protocols, software requirements, data security measures, and modeling standards. Model Element Table: This document details the Levels of Development (LOD) for different model elements, helping project participants understand the reliability and detail of each element. Exhibits: These are agreements on critical aspects such as model sharing, permitted uses, confidentiality, and intellectual property issues. These documents help ensure that all project participants are on the same page regarding the use and management of BIM, leading to more efficient and effective project execution

A. BIM Execution Plan (BEP)
Establishing BIM Goals: “BEP is used to outline the goals of the BIM process.” Benefits of BEP for Project Teams: BEP enables the project team to: Produce the required work and Understand why that work is critical to the project’s success," Data Sharing and Process Understanding: “BEP enables team members that need to share data to understand the process by which that data will be shared and why.” Example of BEP contents:
Note: most firms will start with a template for a BEP and then fill in the information based on the requirements for the project.
BEP depth/length are dependent on the detail and complexity of the project, as well as local regulations. The importance of the plan is less about the length of the document, and more about how it coordinates all the project team members toward achieving their goals for a successful project. BEP enables and dictates the digital project management across the life cycle of a project. BIM goals for the project:
Common goals are:
BIM for team collaboration BIM model uses throughout the project:
BIM for team collaboration
The important of the goals to be clearly indicate is to determine these for team collobration:
how we'll use our modeling to model existing conditions and go through the design process, how this information will be leverage at construction stages: Documentation: in construction through our design documentation Construction Process: the actual construction process itself by our general contractors and subcontractors. Facilities Management: the BIM model be used by facilities management during the design process, as well as after construction is completed?
B. Model Element Table:
Model Element Table is a tool for organizing and managing the various elements of the model.

The key uses of MET are:
Defining Levels of Development (LODs): The table helps project participants select and define the LODs for each model element. LODs indicate the level of detail and accuracy of the model elements at different stages of the project. Assigning Responsibilities: It assigns responsibilities to Model Element Authors (MEAs), who are responsible for developing specific elements to the required LOD. This ensures clarity on who is accountable for each part of the model. Tracking Progress: The table tracks the development of model elements across various project milestones, such as Schematic Design, Design Development, and Construction Documents. This helps in monitoring progress and ensuring that all elements are developed as planned. Enhancing Collaboration: By detailing LODs and assigning responsibilities, the table enhances collaboration among project participants. Everyone involved can see what needs to be done and who is responsible for it, reducing misunderstandings and improving efficiency. Customization: The table can be customized to fit the specific needs of the project, including project phases, abbreviations, and notes. This flexibility allows it to be adapted to different project requirements. Additional Document Refers:
COBie: A digital format used in BIM to collect and organize important project data, like equipment lists, maintenance schedules, and warranties. It replaces traditional paper-based handover documents with a structured digital format. AMS: A system for managing and maintaining facility assets throughout their lifecycle. It tracks performance, maintenance, and costs to ensure assets operate efficiently and last longer. AMS uses data from COBie to manage facility maintenance effectively. C. Exhibits
Exhibits are documents that outline agreements about how BIM data will be used and shared among project participants. They cover things like:
Model sharing: How and when models are shared. Model uses: What the models can be used for. Confidentiality: Rules about data ownership and protection. Insurance: Coverage for risks related to BIM data. They are supplementary materials or appendices that provide detailed information supporting the main contract. The name "exhibit" is derived from the legal and business practice of presenting additional documents or evidence to clarify, elaborate, or support the terms of an agreement.
Differences between Exhibits and the Model Element Table in BIM:
In summary, the main difference between Exhibits and the Model Element Table in BIM is their focus and purpose:
Exhibits are about agreements and protocols. They define how BIM data will be used, shared, and managed among project participants, ensuring everyone understands their responsibilities and the rules for handling BIM data. The Model Element Table is about organizing and defining model elements. It provides a structured way to list and manage the various components of the BIM model, including their details, levels of development, and responsibilities for model authors.
