In this episode, the fifth of the series detailing Building Information Modelling (BIM), Ian takes a look at the fifth area of data collated or the ‘5th Dimension’ of BIM. Ian explains how all the other dimensions are utilised to create the 5th, the project cost estimations and its processes, modelling, software, benefits and challenges.
KEY TAKEAWAYS
- 5D is about real-time cost scheduling with in-process notifications about changes in cost.
- It minimises overspend due to cost reporting and budgeting and informs all areas of the project teams of cost implications and changes.
- Data gathering should be implemented at the very beginning and exhaustive information storage will increase the efficiency of budgeting and cash flow crisis data later on.
- Every single object or asset within the 3D model is cost estimated at the 5D level and is accessible in all the necessary forms from full project cost to individual items and areas.
BEST MOMENTS
‘As per 4D scheduling, you’re integrating your cost data into the model. You can have a library of cost data so you can run from an early stage what you think the project’s going to cost.’
‘By automating the quantification of the building elements with unit price, quantity surveyors or cost engineers can input information into the 3D model so they’ve got a fully interactive process.’
‘If you want to go down the whole online bidding process you can do it online off the basis of this system.’
