VDC Quality Control
Each project presents unique challenges. From design to contracting method, no two projects are completely identical, which requires particular attention to quality control. In short, virtual construction allows us to simulate the construction of a unique building and find issues that would have an impact on quality, schedule and budget.
Before we excavate a site to install underground utilities and form for foundation work, major structural elements such as concrete slabs, foundations, steel, reinforcing and embeds are coordinated in the 3D model. Since several subcontractors typically work on structural elements within a single project, structural coordination helps us to review each sub?s work prior to install and find areas where we may have made differing assumptions.
Absher self-performs much of our own concrete work. Since the structural elements are developed and coordinated in the model, we have an accurate tool to set points for layout on site.? Wall faces, slab edges, penetrations, embeds and grid intersections are a few of the structural components that are typically generated from the coordinated model.? We have seen an increase in our accuracy of layout from this method.
Bid Package Management
As the model is constructed and detailed, a clear picture of the project begins to develop.? This gives our project management team a better understanding of how the project should be broken down into subcontract bid packages.? All elements within the model are given attributes that assign them to an appropriate scope of work.? Any elements not assigned can now be easily tracked and accounted for throughout design development.? With the model separated this way, the model serves as a tool to track subcontractor progress during construction.
