BIM (CAD in 3 D) is a great collaboration tool for large project involving many professionals engineers of various trade and architects. It avoid many error at the design phase, less costly then on construction site.
Adding the 4 dimension with time (schedule) can bring new improvement. Such as changing the sequence of work.
I was involve in a project using BIM, but we didn't try to link with the schedule.
Anyone here was involve in a 4 D BIM
We are interested in 4D, 5D BIM but would like to further to 7D BIM in Ops environment. Our challenge is to decide on the best suited software. We do design work as well as shutdown; quick-paced assistance to our clients. Using successful 4D, 5D BIM will be a strong advantage, however we have not been able to get the right partner for this. Seems software companies want to sell their product only and do not seem interested in developing the right solution for us PM professionals. Anyone have the same challenge?
I am keenly following this discussion. in the last month I have taken every chance to consume information on BIM and how progressive organisations are adopting it in 2018. I have to say I have learnt a lot.
In the last one year I have been involved in a project where though i couldnt have pin pointed it earlier has so many integration similarities with a BIM setup.
We were doing a mineral Separation plant upgrade and we had only a 30 day window of shutdown. We had to make sure we use every capability possible to make this happen and this required advanced planning on our side.
Meet the use of:
1. Navisworks freedom 2017, The whole upgrade was modeled in 3D to ensure a rather sleek visualization of objects in the plant i.e. pumps, pipelines, motors, valves and hoppers.
2. We had a single depository of documentations, drawings and designs so that you have only one source of information for the whole team. You create versions as you go and update so that the next person can access the latest version. Used Sharepoint to make this possible.
3. We build up the Schedule as a direct product of the model. Such that we deconstructed every part of the plant into a single piece, a steel bar, a bolt, a pump, a pipe, a valve, a platform. This enabled us to estimate timeline inform of time to rig from laydown to site, rig it to place, install and bolt it down.
As you can tell it is extreme precision but after weeks of making this possible the implementation and time tracking and progress reporting was a easy part.
This also helped with Material take off and thus procurement was also precise and predictable.
I could go on but the comment is becoming an article in itself.
Bottomline; an Integrated system is the way to go.
Visualizing a project and linking it to schedule is possible and worth the trouble.
To add on to my comment.
All above integration tools and more we used to ensure:
1. Clash Detection - installing different disciplines of materials and equipment means you have to get rid of geometrical inconsistencies earlier before construction starts. Using BIM you bring the plan together in visual to detect clashes and overlaps. you can also modify aesthetic and improve safety in terms of setting up maintenance platforms and work spaces.
2. Mitigate Risks. The best way to avoid rigging issues I found is trying to rig a machine into a plant after building. If it doesn't fit it presents a bigger risk to the project. You can do this with a model and upgrade rigging studies accordingly and in time before construction. This is an easy way to decide the construct-ability and Request for Improvements/Information beforehand.
3. Analysis. What better way would you ask to make discussions on project consumption, machine positions, lay-down areas for different materials and the like? BIM makes this possible.
4. Time and Cost Estimation.$D & 5D)
You get a clear understanding of project phases, budget requirements and formulate alternatives early in the project. This is an effective way to predict consequences into the executive decisions and improve their reliability.
All these measures are to ensure integration. Communication and decision making is so integral that the team is almost always in the same page as to the chages or progress.
6. Quantity Take off
Simply stated; with a model I can count how much material I need and make informed decisions on procurement. If I already have material in the yard, It is an easier way to confirm quantities and quality.
That is a major problem, software company believe they don't need the user's input and that all software can be used out of the box.
A few years ago I was involved in a project to bring 3D parts to one of the 3D design tools. This was financed by a large corporation for its internal use. The 3D design software didn't get involved, not in their business!
but I worked with one person who has done it and he was very upbeat about it, only we got that time disadvantage, and the fact that most others were skeptical been the first time..
