Synopsis: Builders sometimes receive models as part of bid submission and have very tight time-frames for using them to quantify for scheduling and costing.
Techniques will be presented and investigated to extract information quickly from models and test their quality.
Navisworks, ASTA Powerproject, RhinoGrasshopper and Solibri Model Checker will be used.Learning Objectives: 1. ‘- Learn what information that can be quickly extracted from models for 4D construction scheduling and 5D costing.
2. ‘- Learn a range of model checking techniques for construction models
3. ‘- Learn how to link and update 4D & 5D information during the construction phaseBody: Case studies from current projects will be used to demonstrate:
– How to quickly deal with models you get from someone else that you have little or no influence upon. Quantities take-off techniques from Revit schedules for different project phases and level of detail.
– Workflows for testing quality of quantities and reporting objects by level, for detailed trade sub-contracts.
– Common modelling issues to watch for? Which Revit Categories are likely to create problems.
– Differences of Design vs. Construction models. Adding parameters for construction scheduling: Task_ID, Status, LocationZone, to enable cashflow predications and model updates reporting actual cashflow.
– Linking models to construction scheduling using Navisworks and ASTA Powerproject, based on Task-ID sets.
– Solibri Rulesets for project phases, and model visualization will be controlled by Task-ID or by date, for site verification of work progress.
– Creating semi-automated construction schedules using RhinoGrasshopper from RevitIFC models
