Asking “What If” With The 4D BIM Sequencing Project Model

Posted by Patrick Krzyzosiak on Thu, Feb 25, 2016 @ 16:02 PM

“What if?” This tends to be the reoccurring question each project team faces when working with a 4D BIM construction-sequencing model. Model-based sequencing links model elements to schedule activities to develop a construction-sequencing plan. 5D model-based estimating adds in the element of cost to the 3D BIM model. The construction sequencing method is an invaluable resource for developing the project plan for the activity sequence and logistical requirements on an active construction site, or phased occupancy of a renovation, retrofit, addition.

Reaching Target Project Costs with 5D BIM Estimating

Posted by Patrick Krzyzosiak on Thu, Mar 05, 2015 @ 14:03 PM

Reaching project target costs is a whole lot easier with 5D model-based cost estimating. 5D model-based cost estimating links and maps model elements and associated construction quantities to develop a project cost plan. 4D construction sequencing brings the element of time or schedule to the 3D BIM model; 5D brings the element of cost. This cost estimating method is an effective way to work together with the owner and project stakeholders, leveraging a wealth of information and experience from the model to the project in a visually communicative way. Use of 5D model-based cost estimating may still be a fairly new practice for some people. However, I am pleased to report that we’ve had great success using model-based estimating over the past 10 years. This article aims to illustrate how 5D model-based cost estimating can be successfully applied on your next project.
