What BES does
BES (Building Engineering Solutions) is a privately held, electrical-only Building Information Modeling (BIM) and Virtual Design and Construction (VDC) services firm headquartered in Sacramento, California. The company serves US electrical contractors and general contractors across California, Washington, North Carolina, and Texas, with a team of 800 that includes more than 60 dedicated BIM specialists — nearly half of whom hold electrical engineering degrees — and an accumulated 15 years of BIM and 17 years of engineering experience. Its core technology stack is built on Autodesk Revit augmented by 60 internally developed Revit add-ins (including Conduit Offset, 360 Rule, Conduit Kick, and Multi Trim tools) and Navisworks for clash-free coordination. BES delivers the full electrical BIM lifecycle through four service lines: Pre-Construction Redlines (feeder and branch analysis with voltage drop, conduit fill, and derating checks), BIM Modeling and Coordination (LOD 400-500 families with constructability validation), Prefab and Shop Drawings (busway, skid, conduit, support, penetration, and electrical room layouts), and Design-Assistance (floor plans, single-line diagrams, panel schedules to NFPA, ADA, and FHA standards). Beyond the core electrical scope, the firm models Telecommunications, Instrumentation and Control, Fire Alarm, Security and AV, and Building Management Systems (BMS). Its go-to-market is enterprise field sales engaging contractors directly via website inquiries and outbound outreach, with contracts structured as Lump Sum or Time and Materials (with ROM cost estimates and weekly hours reporting on T&M). The firm reports 300 completed projects, 85 current projects, and 50 active clients, and publicly names Tesla, Microsoft, Google, Meta, and AWS among its customer base — pointing to a heavy concentration in hyperscaler and mission-critical data center work, which the company designates as its primary vertical alongside healthcare, industrial, commercial, education, and high-rise residential.
