Building Information Modeling (BIM)

SIL employs Building Information Modeling (BIM) software as part of our continued commitment to design excellence. BIM replaces traditional two dimensional drawings with a complete three dimensional, data-driven model of the structure. Using this technology, we are able to streamline and improve the design and construction process for our clients, project owners, and end users. Successful project experience includes parking garages, fire stations, visitor centers, office buildings, school additions, and multi-story housing.

Our in-house team of trained and certified structural, mechanical, electrical, and fire protection engineers employs an approach to creating BIM design that fosters communication between technical staff and our clients and streamlines the design process. This collaboration leads to successful, responsive and efficient project completion.

These models, developed using various AutoDesk and Bentley MicroStation products, can be used to provide 3-D representations to clients and owners for a clearer approval process. This improved visualization of design has provided the owners a dynamic deliverable. Additionally, the data-driven elements of the model lead to reduced error and risk in design drawings using smart system elements to drive automatic equipment scheduling and labeling.

Using BIM’s conflict identification capabilities, SIL can deliver an exceptionally high quality design resulting in reduced change orders and schedule delays during construction. Design conflicts are identified and remedied long before the project reaches final submittal, resulting in significant cost savings and an expedited construction.

BIM also allows our team to perform detailed design analyses including circuitry checks, light levels, and thermal comfort. SIL can also calculate LEED points, projected cost of energy and carbon footprint for a building, which provides documentation for high performance buildings.
