BIM-Driven Change Orders - Model-Based Cost and Time Assessment in Construction Administration

Course Description

This course introduces licensed professional engineers to practical methods for using BIM platforms and model-based data to evaluate, price, and document construction changes with greater consistency. Through real-world scenarios involving coordination clashes, design evolution, and owner-initiated changes, participants are introduced to frameworks for distinguishing routine field fixes from more significant change events and potential claim situations based on timing, contractual context, and commercial impact. Learners are guided in translating geometric clashes into clear technical scope definitions using systems, extents, trades, and interfaces, applying element-based thinking, comparing before and after model states, and outlining in-scope and out-of-scope work inside digital issue and markup workflows.

The course further introduces a model driven cost workflow that uses delta quantities, appropriate unit or assembly rates, and structured allowances for non-modeled items to create independent checks against contractor pricing and to support more evidence-based negotiation of change orders. Participants are also exposed to basic techniques for relating model changes to schedule activities and milestones at a conceptual critical path level so they can better recognize when changes may be schedule neutral or may warrant time discussions. By the end of the course, learners will have seen how to assemble a concise BIM supported evidence set linking scope, cost, and time considerations and how that information can underpin professional recommendations to accept, negotiate, or question change order proposals.

Learning Objectives

1. Analyze a coordination issue or clash in BIM platforms and define the precise scope of the resulting change.

2. Quantify affected quantities from model views or takeoffs in BIM platforms to estimate the magnitude of a change.

3. Evaluate the cost impact of a change using simple unit-rate or assembly-based calculations linked to model quantities.

4. Analyze how a change affects key schedule activities at a conceptual critical-path level.

5. Design a minimal BIM–based documentation package (issues, markups, attachments) to support a change-order proposal or review.

6. Justify a recommended course of action (accept, negotiate, or reject) for a change order using model-backed evidence from a BIM platform.
