Playback Profiles for 3D Construction Schedule Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction schedule simulation tools fail to effectively highlight critical path activities, making it difficult for schedulers to visualize and manage complex construction schedules due to the equal treatment of all model objects, which is not representative of real-life scenarios.
Innovation Solution
The introduction of 'Playback Profiles' allows users to easily select and highlight key schedule elements, associate static and dynamic appearances with them, and package these profiles for reuse across different models and schedules, enabling a more focused analysis of construction schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all model objects are treated equally in schedule simulation, then the simulation process is simple, but the ability to highlight critical path activities is lost
Solution Approach 1:
The patent applies local quality by differentiating the treatment of model objects based on their schedule importance. Critical path activities are highlighted with distinct visual appearances (such as different colors or highlighting) while non-critical activities maintain standard appearance. This allows the simulation to maintain simplicity for the overall process while providing enhanced visual information for critical elements that require special attention.
2Loss of information
If custom task types are manually created and assigned to each schedule activity, then specific schedule elements can be highlighted, but the process becomes untenable for schedules with hundreds or thousands of activities
Solution Approach 1:
The system implements self-service by automatically identifying and categorizing schedule activities based on their properties and relationships. Rather than requiring manual assignment of custom task types to each activity, the system automatically determines which activities are critical path activities and applies appropriate highlighting. This automation eliminates the burden of manual configuration while still achieving the goal of highlighting important schedule elements.
Solution Approach 2:
The patent utilizes parameter changes by detecting and responding to schedule activity parameters such as critical path status, float values, and dependency relationships. The system dynamically adjusts the visual appearance of model objects based on these parameters, automatically highlighting activities that meet specific criteria without requiring manual intervention. This parameter-driven approach allows the system to adapt to different schedule scenarios automatically.
3Adaptability or versatility
If Task Type assignments are specific to each model/schedule pair, then customization is possible, but the assignments cannot be reused on other model/schedule pairs
Solution Approach 1:
The patent implements universality by creating playback profiles that are independent of specific models or schedules. These profiles contain the logic and rules for identifying and highlighting critical path activities, and can be applied to any model/schedule pair. The profiles are designed to work universally across different construction projects and schedule formats, eliminating the need to recreate customization settings for each new project while maintaining adaptability to different scenarios.

AI summary
A method, apparatus, system, and computer program product provide the ability to simulate a construction schedule. A first three-dimensional (3D) model and a schedule are acquired. The schedule includes activities for building the 3D model. Each of the activities is associated with model object(s) of the 3D model. A subset of the activities is selected based on properties of the activities. A first simulation appearance (of the model objects attached to the selected subset of activities) is defined. A second simulation appearance is defined for remaining/non-selected activities. The selected subset, the first simulation appearance, and the second simulation appearance are packaged into a playback profile that is capable of being applied to a second 3D model. A simulation of construction of the first 3D model (that is based on the playback profile) is played back.
