BIM: Now making construction more efficient

ADG have been working hands-on with BIM technology to streamline construction in ways you may not be aware, so we thought we’d take the time to share it with you this month.

Our team are using BIM in three different ways to improve accuracy and time-efficiency in construction:

  1. Providing construction companies with detailed models to guide accurate, efficient construction at every step of the process.
  2. Delivering construction teams detailed 3D sequencing diagrams to assist in complex construction of components within buildings and facilities.
  3. Modeling construction logistics to assist construction companies in achieving the most efficient staging of scaffold, formwork and site access.

We’ve provided a detailed insight into each of these areas below.

1. Modelling for construction

Very complex details can sometimes be misinterpreted, so our modeling teams have taken construction drawings to a whole new level to assist contractors and subcontractors onsite. Our team now provides detailed 3D diagrams of complex construction details, like modeling a complex steel connection or reinforcement detail so that a contractor can visualise the as-constructed outcome before they build it.

This is a valuable process for structural construction, but also very helpful in mechanical and electrical installation, where the services in a building are tightly connected. Our process shows the contractor how the installation should be done, and shows them a 3 dimensional visual detail to avoid misinterpretation of designs during construction.

2. Detailed sequencing diagrams in supplemental construction documents

The availability of 3D diagrams during construction has been shown to increase accuracy on complex detailing. But we have taken this to a whole new level for instances where sequences of action are required to get construction right.

Our team now provides 3D staging and sequencing drawings that capture very detailed, step-by-step approaches to assembly of a series of elements that need to be installed in a certain order.

Our drawings present the time elements in a sequential format for a complex design such as prefabrication installation on a typical floor layout where it has been designed to have components fitted in a specific order. We find sequential 3D diagrams work better onsite than animation, and supplement animation well for finer detail presentation.

3. Construction logistics models

Our team has been modelling all the scaffold and formwork for whole buildings, offering a new level of planned occupational health and safety (OHS), edge protection and equipment fall protection to contractors prior to site commencement.

These services are being sought out by contractors to validate site planning for council, suggest most efficient site egresses and guide internal safety management processes. It also assists in quantity planning for scaffold and formwork requirements on both small and large projects.

For years, builders have planned their sites laboriously using 2D diagrams to manually map their requirements. This brings a whole new level of sophistication, safety and planning to staged construction.

Our intelligent systems, based on kwikstage Scaffolding, Cuplock, GASS and MevaDec are more advanced than most, and allow us to model all scaffolding systems very quickly and to a high level of detail.

This process has seen a number of clients reposition their cranes for better site layout. They have arranged their scaffold to conform to safety requirements, and to allow for the most appropriate site access and egress based on different stages of the project, as the site moves through working stages of construction in the 3D model.
