RW Allen’s Virtual Construction Team utilizes hardware and software to digitally construct buildings before physical construction begins. RW Allen uses Autodesk Revit to render 3D versions of buildings, or in construction terminology, Building Information Modeling (BIM).
RW ALLEN IS FULLY BIM CAPABLE WITH STAFF TO MODEL YOUR PROJECTS.
The purpose of building facilities digitally is that all “clashes,” or design issues that are not constructible, can be determined and rectified before construction. Examples of clashes include ceiling height that does not account for the necessary duct work. If a clash is found in the field, it can delay construction while the architect and contractor work to determine a solution. Implementing BIM allows greater schedule management and a final project that meets your vision and expectation.
Murphey Middle School
One of the major contributions of RW Allen was the extensive use of building information modeling (BIM). Through the use of RW Allen’s in-house BIM Coordinator, the project team was able to rectify the following:
- Missing structural columns at roof locations.
- Columns designed in the middle of window openings.
- Straight beams specified in radius locations.
- Relocation of ductwork to avoid high ceilings and roof slopes.
- Specifications for glass behind sloped roofs.
- Removal of some exterior windows and the addition of seats to bar joists to eliminate the potential for trapping water around the roof feature and elevator roof.
Through dedication, countless overtime hours, and extensive BIM coordination, the RW Allen team was proud to present a modern facility that includes large storefront windows installed on a radius wall, bright tall open common area with Fabric Drum Style LED Lighting Fixtures, Monumental Stairs with Concrete Monolith Feature, terrazzo flooring, acoustical sound panels, and state of the art STEM equipment, right on time for the first class bell.
During the construction of Whitehead Elementary, the BIM team modeled the entire project, beginning with the structure and mechanical systems. During modeling, we discovered that the ductwork was too large to fit within the ceilings. The system called for one return air duct and one supply duct from the 3rd floor to the mezzanine to each hallway on the first and second floor of the school. Because of the size requirements as drawn, the ductwork was too large to fit within the ceiling, causing the system to be installed below the ceiling. The other option would be for the architect and engineer to reconfigure the steel structure of the entire facility, causing major delays in project completion. Not wanting a construction delay, our BIM team got to work, looking at alternative duct options to work within the current ceiling system. Digitally experimenting with different size ducts and split airflows, the BIM team successfully redesigned the entire duct design to fit within the existing ceiling design without having to raise steel. Because of BIM, the Owner experienced significant cost and time savings.
Merial’s existing location included interstitial space above the first floor which housed its mechanical units that serviced the entire facility. The interstitial space had low eave heights in addition to housing the support structure for the mechanical units. But Merial needed more space and wanted to use a portion of the interstitial space for additional offices. Through the use of BIM, RW Allen was able to determine the usable space and the relocation methods to convert the interstitial space into a second floor. Through this solution, RW Allen was able to provide significant cost savings because Merial did not have to build another facility in order to expand.
