Computer modeling allows Spectrum Engineers’ clients to envision and experience their building and ensure that specifications are realized at the onset of a project. For example, building information models (BIM) allows mechanical/electrical/plumbing systems to be designed, viewed, altered and updated as they interact with each other, the architecture and the structural elements. BIM uses this knowledge to model the way these systems would interact in real situations. Other computer modeling services offered include computer modeling for energy, sound and lighting analyses to test effects of acoustical and lighting specifications. Computer modeling is especially important to maintaining budgets and schedules on today’s complex facilities.
