Low Voltage and Communications Estimating
Device counts, cable lengths and pathway quantities for data, fire alarm, security and audiovisual systems.
Low Voltage and Communications Estimating Overview
Low voltage systems are priced by device count and cable footage, plus the pathways, terminations and testing that make them work. We count devices from the technology, security and fire alarm plans, estimate home-run cable lengths, and list head-end equipment from the riser diagrams.
Power wiring, lighting and distribution are covered on our electrical estimating page; low voltage can be estimated on its own or combined with it.

Construction Estimating FAQ
Low Voltage Estimating Questions
Yes. Each system is a separate section in the estimate, so you can bid them independently or as one package.
We measure home runs from each device to its telecom room along the likely corridor route and add a stated slack allowance. The method is listed in the estimate so you can adjust it.
