Lindley Fire is experienced in every facet of underground/overhead fire sprinkler design. We can meet any type of design challenge -- from normal to special hazards -- affording protection for buildings millions of square feet in size. Our designers work closely with all project principals -- architects, developers, municipal agents and insurers -- to provide maximum quality and cost-effectiveness. The use of computer-aided design (CAD) contributes to the accuracy of a system's design and helps expedite the project, which translates into cost savings for our clients.
