Quarterly Update: BIM News
At Walbridge, we’ve created an innovations team to focus on the development and use of Building Information Modeling tools. The Walbridge Innovations Group researches current software, hardware, methods and tools to reduce project cost and schedule and improve the overall quality of the resulting product. All services shown are available utilizing Walbridge in-house staff, ensuring confidentiality and low project costs.
The construction industry has only begun to tap the potential of Building Information Modeling. Project teams are increasingly using 3D models created by the Architect/Engineering team to coordinate design and identify clashes between building systems. Using BIM, interference or clashes can be fixed within the model, eliminating expensive and time-consuming rework in the field.
For years, laser scanning has been used to create models of existing conditions in completed buildings. When used with proper planning and expectations, scanning can be a valuable tool in the creation of 3D models. These models can become the basis for design renovations, filling in the gaps of missing or inadequate as-built documents.
Using Primavera P6, the 3D model can be linked to the planned project schedule (4D), helping the project team visualize major trade work coordination including site work, concrete, steel, siding and roofing. Walbridge then integrates site logistics into the plan and studies alternate sequences, means and methods in modeled form.
The 3D model also assists the team in the logistical planning of the project. The Walbridge Innovations Group has developed techniques to identify the best solutions to solve site logistical issues using BIM tools (XD).
Many of the models created today only meet the needs of the design team. Walbridge’s innovative models can be useful during construction and beyond. Creating modeling specifications and protocols prior to the design’s start, we can significantly increase team productivity. Identifying user needs early, we reduce the need for and frequency of project element remodeling. Rebuilding the model allows us to break out the elements that can be used to generate more accurate budgets (5D) and quickly resolve what-if questions.
Walbridge is working with a software developer to support what-if scenarios to help our customers quickly visualize their options and the associated impact to cost and performance. This valuable pre-construction tool continues to evolve. With a few hours notice, the Walbridge Innovations Group can develop a base model for brainstorming discussions with you, developing budgetary pricing within +/- 10% accuracy.
The power of Building Information Modeling continues to evolve at jobsites. Opportunities exist to capture as-builts in real-time by projecting a hologram or providing laser-guided placement of systems to match the model. Additional opportunities to increase productivity will result from tradesmen seeing the day’s work prior to entering the field.
An up-to-date progress model can be useful in differentiating percent complete, monitoring start-up, communicating progress and identifying available areas of work.
The BIM model could be utilized to calculate and record the carbon footprint associated with the construction process.
Finally, a true BIM model is one where the information gathered during the design and construction phases can be directly uploaded to a facilities management software package for use throughout the life of the new facility.
As software technology advances, construction professionals and BIM technicians expand the use of BIM in ways that will change our industry for the next generation of builders.
