Fire safety consultants help developers comply with fire safety requirements for new and refurbished constructions. They create comprehensive fire safety documents detailing how a building meets requirements related to compartments, exits, materials, alarms, sprinklers and more. Previously, these documents used paper sketches but have now switched to digital sketches in Revu for advantages like easier sharing, annotation and updating and to support a paperless office. Revu provides tools like measurements, standard symbols and text boxes to annotate digital sketches and ensure buildings meet all necessary fire safety standards.
