Hensel Phelps takes BIM to the site - real time access on the fly
Easy coordination and communication tool
Hensel Phelps – a General Contractor based in Colorado with districts all around the United States – is currently constructing a design-build data center. The project involves a great deal of coordination between all divisions of construction, specifically MEP and structural elements of the building.
Project requirements stipulate all designers and subcontractors provide accurate, current Revit models throughout design and construction.
With access to highly detailed models, the project team is using Tekla BIMsight extensively as a coordination and a communication tool. The company has constructed a mobile jobsite kiosk which allows easy access to digital drawings and the Tekla BIMsight models. Any worker on-site can go to the kiosk to work out field issues, check RFIs, navigate the models, and come to resolutions - all without having to come back to the job trailers.
Office Engineer Andrew Martin is pleased: "Tekla BIMsight has been an awesome, easy to use tool which our project is using every day. It is such a well-developed tool that all levels of jobsite workers use it; from carpenter to architect. The value of Tekla BIMsight has been demonstrated by enabling real time access to design information 'on the fly' in the field."
Superintendents, Field Engineers, Quality Control – everyone is using it
About 15 members of the Hensel Phelps project team are currently using Tekla BIMsight on a daily basis. The team explained, their Superintendents utilize Tekla BIMsight as a communication and coordination tool between trades. The project is very mechanically and electrically involved, so Tekla BIMsight allows sequences of work to be visualized in order to efficiently construct complex MEP elements of the building.
As a general contractor, Hensel Phelps self-performs cast-in-place concrete and backfill operations. Field engineers provide layout and control for the craft putting the work into place, using Tekla BIMsight as a tool when creating foundation lift drawings, in order to identify any design conflicts before work begins. Also, the engineers and carpenter foreman have had great success when collaboratively reviewing the models to better understand what needs to be constructed.
Due to the extensive MEP coordination efforts needed during the design/build process, quality control personnel have implemented the use of Tekla BIMsight as a clash detection tool. Additionally, Tekla BIMsight is used by quality control members in the field during inspections. Using a DELL XPS 12 hybrid PC, the model can be referenced to ensure correct as-built conditions compared to the design intent.
Working on site with 3D
The model-based workflow has been a success. The team explained how seeing the building in 3D is much easier to understand than looking at paper drawings. "With Tekla BIMsight being so fast, our field craft (foreman and carpenters) are able to go to our mobile, tablet-based kiosk, and look at the model. The program is very simple and takes only a few minutes to teach someone how to use the program. We had a foreman reviewing the drawings and could not visualize what he was supposed to build. He went and pulled up the 3D model in Tekla BIMsight and he immediately understood what he was supposed to build," they continued.
Hensel Phelps has found the Clip Plane function a very useful feature of Tekla BIMsight. "We often use it during subcontractor meetings. During this time, the project schedule and upcoming scopes of work can be visually compared, in order to facilitate better communication between trades, and sequences of work," stated the Hensel Phelps staff.
Tekla BIMsight as part of project management
Hensel Phelps also explained how they plan on using Tekla BIMsight in the future: "Tekla BIMsight has been a great, easy-to-use tool, which we have used extensively on this jobsite. The continued use of this software plays into Hensel Phelps' real-time, cloud-based, integrated building and management technology solution, affectionately known as MEO, which stands for Modular Electronic Office. MEO is a suite of innovative tools and best practices that enhance project management, and ensure real-time communication and collaboration — so obstacles are eliminated, and opportunities are quickly seized."
